Authors: Arunthanachaikul Thunyawarin , Osothsinlp Sornwit , Nivatwongs Saisuree , Narongroeknawin Pongthorn
Published: December 2024

Introduction

Sudden sensorineural hearing loss (SSNHL) is idiopathic in 70–90% of cases with 10–30% linked to vascular injuries, viral infections, or autoimmune inner ear disease (AIED). AIED contributes to less than 1% of all hearing losses, categorized into primary, affecting only the inner ear, and secondary, associated with systemic autoimmune diseases (SAID). This study examines the prevalence and features of AIED in SSNHL in a tertiary referral center.

Materials and Methods

We conducted a prospective study from November 2021 to December 2022 including SSNHL patients who exhibited symptoms like hearing loss or tinnitus. Evaluations included tympanometry, pure tone audiometry, and blood tests, with suspected AIED cases further assessed by rheumatologists using Lobo's diagnostic criteria. Treatment responses were monitored through regular audiometry updates.

Results

Out of 694 SSNHL patients, 43 (6.2%) were diagnosed with AIED, of which 36 (83.7%) had primary AIED and 7 (16.3%) had secondary AIED linked to conditions like Sjögren's syndrome and systemic lupus erythematosus. Treatment response was seen in 19.4% of primary and 42.9% of secondary AIED cases.

Conclusion

The prevalence of AIED in SSNHL patients was found to be 6.2%, with a notable fraction also suffering from SAID. Responses to treatment were positive in about a third of these cases, highlighting the importance of interdisciplinary management for this rare yet significant cause of SSNHL.

Published: December 2024

Objective

To compare the feasibility and outcomes of vestibular rehabilitation (VR) for persistent postural-perceptual dizziness (PPPD) with those for chronic unilateral vestibular hypofunction (UVH).

Study Design

Prospective study.

Setting

Tertiary referral center.

Patients

Nineteen consecutive patients with chronic UVH lasting for >3 months and 15 with PPPD.

Interventions

The VR program consisted of gaze stabilization exercises, static or dynamic balance exercises and gait training, and habituation exercises that exposed patients to a provocative stimulus. Patients were asked to perform VR for at least 20 min a day.

Main Outcome Measures

Status of VR (i.e., continuation/discontinuation) and outcomes were assessed 1 month after the introduction of VR using the Dizziness Handicap Inventory for handicaps in daily life due to dizziness, the Niigata PPPD Questionnaire (NPQ) for symptom exacerbations of PPPD, and the Hospital Anxiety and Depression Scale for anxiety and depression.

Results

No patients in the chronic UVH group discontinued VR, whereas six patients in the PPPD group discontinued VR owing to symptom exacerbations, showing a significant difference. VR did not decrease any symptom scale, except for the NPQ-motion subscore, in patients with PPPD who continued VR, whereas it decreased all clinical symptom scales, except for the NPQ-motion subscore, in patients with chronic UVH.

Conclusions

Patients with PPPD had a higher rate of VR discontinuation than those with chronic UVH, and VR was less effective in patients with PPPD who even continued treatment than in those with chronic UVH. Therefore, VR on PPPD should be optimized.

Dr Saul Hertz (1905–1950) conceived and brought from bench to bedside the medical uses of radioiodine. The early history of radioiodine has been compromised with inaccuracies. This article uses primary-source verification to put forth an evidence-based history of the origin of nuclear medicine. Hertz’s paradigm-changing work is a seminal medical discovery of the 20th century. Dr Hertz’s legacy continues to evolve.
Spinal Anatomy Ultrasound in Young Infants With Implications for Lumbar Puncture
Authors: Rinaldi Margaret B. , Lipton Matthew , Kidd Rebecca , Arnold Donald H. , Levine Marla C.
Published: December 2024

Background:

Lumbar puncture (LP) in young infants may challenge clinicians due to the infrequency of the procedure and anatomic variability. The use of ultrasound (US) to characterize young infant spinal anatomy prior to performing an LP may help determine the most favorable site for intervention.

Objectives:

1) Evaluate potential sites for LP in young infants with US at L2/L3 through L5/S1 to determine differences in needle insertion depth (NID), spinal canal width (SCW), and subarachnoid fluid width (SAW).

2) Describe the location of the conus medullaris.

3) Predict NID of L2/L3 through L5/S1 based on variables including age, gestational age, height, and weight.

Methods:

We studied a convenience sample of participants aged 0–6 months in a tertiary children's emergency department. We recorded characteristic data and used a Sonosite PX US with a linear 15-MHz transducer to image each participant's spine. We used the paired t-test to examine univariate differences in NID, SCW, and SAW and multiple linear regression models to derive predictive equations for NID.

Results:

Among 50 participants, the mean NID for sites L2/L3 through L5/S1 did not differ significantly; however, at sites L2/L3 through L5/S1, there were statistically significant differences in the mean SCW and mean SAW, which were both consistently measured to be larger the more cephalad the site. Weight was the only statistically significant variable associated with NID after adjusting for other covariates.

Conclusions:

Spinal canal width and SAW were consistently measured to be larger at more cephalad sites, suggesting there is a larger target fluid volume available at higher interspaces. Subarachnoid fluid width was measured to be small, highlighting the importance of precise movements. Location of the needle site did not change expected needle depth (approximately 1 cm across all sites). The conus medullaris was not often visualized while scanning the L2/L3–L5/S1 interspaces. Weight can be used to estimate optimal NID; although, it is unclear such small differences would have clinical significance.

Published: December 2024

Objective:

Among children transported by ambulance across the United States, we used machine learning models to develop a risk prediction tool for firearm injury using basic demographic information and home ZIP code matched to publicly available data sources.

Methods:

We included children and adolescents 0–17 years transported by ambulance to acute care hospitals in 47 states from January 1, 2014 through December 31, 2022. We used 96 predictors, including basic demographic information and neighborhood measures matched to home ZIP code from 5 data sources: EMS records, American Community Survey, Child Opportunity Index, County Health Rankings, and Social Vulnerability Index. We separated children into 0–10 years (preadolescent) and 11–17 years (adolescent) cohorts and used machine learning to develop high-specificity risk prediction models for each age group to minimize false positives.

Results:

There were 6,191,909 children transported by ambulance, including 21,625 (0.35%) with firearm injuries. Among children 0–10 years (n = 3,149,430 children, 2,840 [0.09%] with firearm injuries), the model had 95.1% specificity, 22.4% sensitivity, area under the curve 0.761, and positive predictive value 0.41% for identifying children with firearm injuries. Among adolescents 11–17 years (n = 3,042,479 children, 18,785 [0.62%] with firearm injuries), the model had 94.8% specificity, 39.0% sensitivity, area under the curve 0.818, and positive predictive value 4.47% for identifying patients with firearm injury. There were 7 high-yield predictors among children and 3 predictors among adolescents, with little overlap.

Conclusions:

Among pediatric patients transported by ambulance, basic demographic information and neighborhood measures can identify children and adolescents at elevated risk of firearm injuries, which may guide focused injury prevention resources and interventions.
The T﻿urkish Version of the Revised Nottingham Sensory Assessment: Validity and Reliability in Chronic Stroke Survivors
Authors: Bilgin Nurten , Akyurek Gokcen
Published: December 2024

Background:

Evaluation of sensory functions in chronic stroke survivors is essential to plan and implement effective treatment and rehabilitation.

Objective:

To investigate the validity and reliability of the Turkish version of the Revised Nottingham Sensory Assessment (rNSA-T) in chronic stroke survivors.

Methods:

We applied the World Health Organization’s translation protocols to develop the rNAS-T. We then tested its validity and reliability in 85 chronic stroke survivors using criterion validity and consistency for demographic variables, as well as﻿ test-retest and inter-rater reliability analyses﻿.

Results:

The criterion validity of the rNSA-T was supported by significant correlation between participants’ scores on the rNSA-T, the Katz Index of Independence in Activities of Daily Living (Katz-AD) (r = 0.430–0.674, P < 0.05), and the Rivermead Motor Assessment (RMA) (r = 0.528–0.773, P < 0.05). rNSA-T results remained consistent across variables of sex and side affected by stroke (P > 0.05). The test-retest reliability of the rNSA-T was excellent in all subdimensions (ICC = 0.865–1.000), as was the inter-rater reliability (κ = 0.875–1.000).

Conclusion:

The rNSA-T is a valid and reliable tool for evaluation of sensory functions in chronic stroke survivors.
Stress internalization associated with cognitive decline among older U.S. Chinese
Authors: Chen Michelle H , Ma Yiming , Verma Charu , Bergren Stephanie , Dong XinQi , Hu William T
Published: December 2024

INTRODUCTION

Behavioral and sociocultural factors in minority populations in the U.S. are commonly examined as independent contributors or buffers to health disparities in cognitive decline, but can demonstrate significant inter-relatedness due to broader contextual factors (e.g., acculturation). Analyzing influence of correlated behavioral and sociocultural traits can better identify targets for future intervention. The current study aimed to account for interdependent risk and resilience factors associated with cognitive decline in non-demented older U.S.-dwelling Chinese adults.

METHODS

The sample consisted of 1,528 older U.S. Chinese (60 and older) with normal cognition and function at baseline who attended three waves of the Population Study of ChINese Elderly (PINE). We used principal component analysis to generate memory and executive functioning outcomes; factor analysis to reduce behavioral and sociocultural variables into latent constructs; and linear mixed-effects models to evaluate the impact of these constructs, as well as of demographic and medical factors (e.g., cardiovascular disease), on longitudinal rates of cognitive decline.

RESULTS

Factor analysis identified three main behavioral/sociocultural constructs: stress internalization, neighborhood/community cohesion, and external social support. Among these, only stress internalization – consisting of greater perceived stress, greater hopelessness, and lower conscientiousness – was associated with longitudinal decline in memory, while none with decline in executive functioning. Neither acculturation nor social engagement was related to decline in memory or executive function, even though participants with greater acculturation or social engagement had better baseline cognitive performance.

DISCUSSION

Using a psychometrically and statistically robust model, we found that only the factor underlying stress processing, hopelessness, and conscientiousness was associated with rates of memory decline in this older non-demented U.S. Chinese cohort. These maladaptive traits have been linked to the Asian model minority stereotype but all the same potentially modifiable. Future studies examining disparate health outcomes must account for inter-relatedness among behavioral and sociocultural factors to identify root causes.
The intersection of inflammation and DNA damage as a novel axis underlying the pathogenesis of autism spectrum disorders
Authors: Jhanji Megha , Krall Colleen L. , Guevara Alexis , Yoon Brian , Sajish Mathew , Boccuto Luigi , Lizarraga Sofia B.
Published: December 2024

Autism spectrum disorders (ASD) affects 1 in 36 children and is characterized by repetitive behaviors and difficulties in social interactions and social communication. The etiology of ASD is extremely heterogeneous, with a large number of ASD cases that are of unknown or complex etiology, which suggests the potential contribution of epigenetic risk factors. In particular, epidemiological and animal model studies suggest that inflammation during pregnancy could lead to an increased risk of ASD in the offspring. However, the molecular mechanisms that contribute to ASD pathogenesis in relation to maternal inflammation during pregnancy in humans are underexplored. Several pro-inflammatory cytokines have been associated with increased autistic-like behaviors in animal models of maternal immune activation, including IL-17A. Using a combination of ASD patient lymphocytes and stem cell-derived human neurons exposed to IL-17A we discovered a shared molecular signature that highlights a metabolic and translational node that could lead to altered neuronal excitability. Further, our work on human neurons brings forward the possibility that defects in the DNA damage response could be underlying the effect of IL-17A on human excitatory neurons, linking exacerbated unrepaired DNA damage to the pathogenicity of maternal inflammation in connection to ASD.
Global analysis of fragmentation functions to charged hadrons with high-precision data from the LHC
Authors: Gao Jun , Liu ChongYang , Shen XiaoMin , Xing Hongxi , Zhao Yuxiang
Published: December 2024

Fragmentation functions (FFs) are essential nonperturbative QCD inputs for predicting hadron production cross sections in high energy scatterings. In this study, we present a joint determination of FFs for light charged hadrons through a global analysis at next-to-leading order (NLO) in QCD. Our analysis incorporates a wide range of precision measurements from the LHC, as well as data from electron-positron collisions and semi-inclusive deep inelastic scatterings. By including measurements of jet fragmentation at the LHC in our global analysis, we are able to impose strong constraints on the gluon FFs. A careful selection of hadron kinematics is applied to ensure the validity of factorization and perturbative calculations of QCD. In addition, we introduce several methodological advances in fitting, resulting in a flexible parametrization form and the inclusion of theoretical uncertainties from perturbative calculations. Our best-fit predictions show very good agreement with the global data, with χ2/Npt∼0.90. We also generate a large number of Hessian error sets to estimate uncertainties and correlations of the extracted FFs. FFs to charged pions (kaons and protons) are well constrained for momentum fractions down to 0.01 (0.1). Total momentum of partons carried by light charged hadrons are determined precisely. Their values for u, d quarks and gluon saturate at about 50% for a lower cut of the momentum fraction of 0.01. Comparing our determinations to results from other groups, we find significant discrepancies, particularly for the proton fragmentation functions, as well as for gluon and unfavored quarks to pions and kaons. Pulls from individual datasets and impact of various choices of the analysis are also studied in details. Our analysis raises questions concerning existing and future experimental measurements, including the need for clarifications on the definitions of various hadron final states and the necessity of further measurements on fragmentation from heavy quarks. Additionally, we present an update of the program used for calculating hadron production cross sections. We demonstrate the broad applications of the program combined with our new FFs, including NLO predictions on jet charges in proton collisions and reference cross sections for heavy-ion collisions, which show good agreement with LHC data. Our FFs, including the error sets (denoted as NPC23), are publicly available in the form of LHAPDF6 grids.

Optical quantum sensing for agnostic environments via deep learning
Authors: Zhou Zeqiao , Du Yuxuan , Yin Xu-Fei , Zhao Shanshan , Tian Xinmei , Tao Dacheng
Published: December 2024

Optical quantum sensing promises measurement precision beyond classical sensors termed the Heisenberg limit (HL). However, conventional methodologies often rely on prior knowledge of the target system to achieve HL, presenting challenges in practical applications. Addressing this limitation, we introduce an innovative deep-learning-based quantum sensing scheme (DQS), enabling optical quantum sensors to attain HL in agnostic environments. DQS incorporates two essential components: a graph neural network (GNN) predictor and a trigonometric interpolation algorithm. Operating within a data-driven paradigm, DQS utilizes the GNN predictor, trained on offline data, to unveil the intrinsic relationships between the optical setups employed in preparing the probe state and the resulting quantum Fisher information (QFI) after interaction with the agnostic environment. This distilled knowledge facilitates the identification of optimal optical setups associated with maximal QFI. Subsequently, DQS employs a trigonometric interpolation algorithm to recover the unknown parameter estimates for the identified optical setups. Extensive experiments are conducted to investigate the performance of DQS under different settings up to eight photons. Our findings not only offer a different lens through which to accelerate optical quantum sensing tasks but also catalyze future research integrating deep learning and quantum mechanics.

Optically dressed three-level coherence in neutral bosonic alkaline-earth-like species
Authors: Robert P. , Sabulsky D. O.
Published: December 2024

Addressing the optical clock transition of alkaline-earth-like atoms has garnered increasing interest in the context of a future redefinition of the second, as well as for fundamental physics based on inertial sensors. To be accessible in bosonic alkaline-earth-like atoms, this transition necessitates external coupling. Here we propose a scheme utilizing midinfrared to deep-infrared optical dressing to drive a three-level coherence that mixes into and therefore addresses the optical clock transition of bosonic alkaline-earth-like atoms.

Published: December 2024

We study a slender filament beating in a viscous fluid with novel curvature-dependent bending stiffness. Our numerical and experimental investigations reveal that such differential stiffness can sustain planar bending waves far along flexible filaments, in stark contrast to the uniform-stiffness case which requires more sophisticated control. In particular, we establish basal actuation as a viable, parsimonious mechanism for generating high-amplitude planar bending waves. Moreover, the resulting beat patterns closely resemble the power-and-recovery strokes of propulsive biological filaments such as cilia, suggesting extensive applications in robotic and engineered systems.

Essential knowledge, values and pedagogies for teaching global citizenship education in Hong Kong
Authors: Chong King Man Eric , Cheng Chi-Keung Eric
Published: December 2024

Purpose

This study aims to explore various conceptions of global citizenship education (GCE) and pedagogies among frontline Chinese Hong Kong secondary school teachers under the onset of a new political climate of conservative nationalism.

Design/methodology/approach

It utilised interview findings with a purposive sample of about 22 experienced secondary school teachers in 2019, which was shortly before the city was caught in huge waves of protests. Interviewees come from different demographics, such as subsidy types of schools and school sponsoring bodies and admit students of different socio-economic status and academic capabilities.

Findings

The findings reveal both liberal and nationalistic orientations on knowledge and values of GCE, including sustainability, in recent school education, and the use of discussion and experiential learning for teaching GCE.

Research limitations/implications

A conceptual framework is developed for further research on teaching GCE in different cultural contexts. Developing pedagogies to instil in learners the values, attitudes and behaviours that support responsible global citizenship should become an international research agenda.

Originality/value

The analysis offers insightful views on what, why and how these teachers teach GCE. The authors also construct a framework of teachers' values and teaching beliefs that cultivate global citizens based on the research findings. This framework can inform school leaders, curriculum planners and teacher trainers in developing a more substantial pedagogical framework for GCE.
Local suppliers’ power and its effects on buyers’ reaction
Authors: Liu Feng Hsu
Published: December 2024

Purpose

The selection of capable suppliers in emerging markets raises an interesting dilemma. It might be risky if capable partners grow and behave opportunistically; on the other hand, it might be beneficial to form a relationship with a capable local supplier in an emerging market. To select capable local suppliers with expected increasing power, there is potential for more research on how foreign buyers govern their relationships with various governance modes to influence their capable suppliers’ behavior.

Design/methodology/approach

The partial least squares method was used to analyze and find direct support for the authors’ hypotheses based on cross-sectional data from a sample of 134 Taiwanese manufacturers.

Findings

The empirical results of this study indicate that local suppliers with greater supply chain integration and better supply chain agility directly increase power relative to that of buyers and indirectly have a positive impact on two relational development models adopted by buyers (relationship learning and codevelopment) through collaborative communication.

Originality/value

While selecting capable suppliers can enhance a buyer’s competitive edge, it is important to carefully consider and manage potential negative effects, such as increased dependency and power imbalances. This research demonstrates that two capabilities of local suppliers, i.e. local supply chain agility and local supply chain integration, influence the power of local suppliers.
Financial statement comparability and cash holding: moderated by ESG performance in Indonesia
Authors: Soetanto Tessa Vanina , Agustia Dian
Published: December 2024

Purpose

The paper examines the impact of financial statement comparability on cash holding moderated by Environmental Social Governance (ESG) performance.

Design/methodology/approach

A panel dataset of all publicly listed Indonesian firms from 2009 to 2022, evaluated with panel data regressions controlled by year and clustered by firms was the method of study. Then, a robustness test using alternative measurements, lagged variables and additional analyses are performed.

Findings

The result shows that there is no moderating role of ESG performance on financial statement comparability toward cash holding among Indonesian firms; nonetheless, ESG performance strengthened the capacity of financial statement comparability to lower cash holding significantly for firms with high ESG performance scores and not significant otherwise. This interplay of variables is developed following the Financial Services Authority imposed ESG regulation for publicly listed firms in Indonesia. Further, the analyses reveal that higher ESG performance can help firms achieve high market-based performance and make it easier to obtain external financing, thus lowering the need to hold more cash.

Originality/value

The study highlights the effect of financial statement comparability on cash holding, particularly moderated by ESG performance in a developing country where the agency cost is high and still very rare to be scrutinized. Additionally, the study helps to know the impacts prior and post-ESG regulation imposed in Indonesia.
A mechanistic study of the influence of quantum leadership on employees’ constructive deviance
Authors: Zhang Yuqi , Chen Xue , Tan Chunping
Published: December 2024

Purpose

This paper aims to understand how quantum leaders influence employee work behavior through effective tasks.

Design/methodology/approach

In this study, 516 questionnaires were collected using the interval data method to explore the triggering mechanisms and paths of emerging quantum leadership on constructive deviance.

Findings

The findings indicate that quantum leadership promotes constructive deviance through facilitating recovery experience (affective path), job crafting (task path) and the chained mediation path between the two. Additionally, the moderating effect of openness to experience strengthens the pathways between quantum leadership and recovery experience, and between quantum leadership and job crafting.

Research limitations/implications

This study focuses closely on the mechanism of leadership behavior on employees, neglecting the psychological state and behavior of the leader as a key resource element in the work environment. Quantum leadership emphasizes value-bound characteristics, so the role played by quantum leaders may vary in different cultures and values.

Practical implications

First, this study calls for the organizational management focusing on the advantages of quantum leadership thinking and its positive effects in practice. Second, the mediating mechanisms of recovery experience and job crafting provide insights into how quantum leadership can be used to enhance constructive deviance. Third, this study elucidates how individual responses to organizational environment and leadership style vary in management practices. Our study helps managers better understand how individual characteristics, such as openness to experience, influence managerial behavior.

Social implications

This study enriches the qualitative research on emerging “quantum” perspectives of leadership, expands the mechanism of employee constructive deviance and highlights the need for organizations to take measures that encourage constructive deviance by their employees, as this can lead to high-quality and long-term growth.

Originality/value

Based on conservation of resources theory, authors revealed the mechanisms by which quantum leadership influences employees’ constructive deviance, confirming the mediating role of recovery experience and job crafting as well as the moderating role of openness to employee experience. We explored the moderating mechanisms of the individual trait of openness to experience in the quantum leadership-to-job crafting and the recovery experience-to-job crafting.
Institutions, the entrepreneurial orientation and innovative capabilities of countries: the moderating effect of technological development
Authors: Ferreira João J.M. , Fernandes Cristina I. , Veiga Pedro Mota
Published: December 2024

Purpose

The impacts of institutions on entrepreneurship and innovation, as well as the effects of technological development, have been subject to various research studies. While this theme inherently remains a focus for political decision-makers, there is very little knowledge on the combined role of institutions, entrepreneurial orientations and innovation capabilities on the technological development of countries. In this study, we examine the impacts of entrepreneurial orientation and the innovative capacity of countries through considering the moderating effect of technological development.

Design/methodology/approach

The data used in this study has been collected from various sources, including the World Economic Forum United Nations (UN), World Bank (WB), Organization for Economic Cooperation and Development (OECD), World Intellectual Property Organization (WIPO), National Consortium for the Study of Terrorism and Responses to Terrorism (START) and Scimago. The study focuses on 86 countries that are either at stage 2 or stage 3 of development or in the transition from stage 2 to stage 3.

Findings

We have found that corporate governance, property rights and security institutions have a positive influence on a country’s entrepreneurial mindset and its ability to innovate. Additionally, we have noted that technological advancements also play a role in moderating this relationship. These findings have important implications for the theory, practice and public policies in this area.

Originality/value

This study emphasizes the substantial impact of institutional quality on the entrepreneurial mindset and innovation capabilities of businesses. It shows that perceiving institutions as more stable can have a positive effect on both entrepreneurial orientation and innovative capabilities, ultimately improving companies' competitiveness.
Can understanding self-congruency help educators in deterring students from using ChatGPT?
Authors: Gorkhali Anjee , Shrestha Asim
Published: December 2024

Purpose

Educators are raising ethical concerns over the use of ChatGPT in schools. They have implemented various strategies to minimize its use, particularly by labeling ChatGPT-produced work as plagiarism. However, the use of ChatGPT among students is still on the rise. Our study aims to find the behavioral motivation behind students’ increased use of ChatGPT.

Design/methodology/approach

We use PLS-SEM to analyze survey responses from 250 participants in a liberal arts university in the USA.

Findings

Students’ self-congruency influences their attitude and behavioral intention toward ChatGPT. Students use ChatGPT because they find a higher similarity between their personality and the persona depicted by ChatGPT. So, educators must consider creative assignments that cannot be solved using ChatGPT because any other deterrence will not minimize students’ use of ChatGPT.

Originality/value

To the best of our knowledge, this is the first research to incorporate students’ behavioral motivation and integrate self-congruency to find the antecedents of increased use of ChatGPT in the education sector.
Building didactic knowledge from reflection in lesson studies
Authors: Fonseca Gorete , da Ponte João Pedro
Published: December 2024

Purpose

The study aims to understand what learning is evidenced regarding knowledge about the teaching of mathematics by five primary teachers when they reflect on research lessons. To do so, we used situations from the formal and informal reflection sessions that took place after teaching four research lessons.

Design/methodology/approach

It is a qualitative and interpretative research. Data collection was done by participant observation with elaboration of a research journal, audio recording of sessions and a whole-group interview. Data analysis was made by content analysis based on the conceptual framework.

Findings

The study shows the relevance of carrying out successive research lessons, followed by moments of formal and informal reflection, leading to improvements in relation to the way the task is proposed to the pupils, the representations used and the monitoring and questioning carried out by the teacher in the various phases of the lesson.

Originality/value

In lesson study, very often, only one research lesson is held. This case shows the potential of successive research lessons, each of which is followed by moments of reflection, in promoting the development of teachers’ didactic knowledge, namely regarding teaching practice, providing a more in-depth look at the way pupils work on mathematical tasks and the role of the teacher in promoting learning. Reteaching proved to be a valuable strategy to support teachers’ reflections in order to improve the leading of pupils’ work.
Implementation of regenerative business models in transitioning companies – are middle managers ready for action?
Authors: Gervais Florence , Coulombel Philippe , Okeke Okeoma John-Paul
Published: December 2024

Purpose

This study aims to address a substantial research gap regarding the implementation of regenerative business models (RBMs). Drawing on complementary organizational behaviour theories, it explores the role of middle managers in this process and how to move them to action.

Design/methodology/approach

A sample of 14 French companies, whose CEOs have publicly announced a transition to RBM, was identified. In each company, a middle manager involved in implementing RBM changes was interviewed using a qualitative expert interview methodology.

Findings

The findings confirm the pivotal role of middle managers in achieving business model changes. Three major influencing factors combine to form a typology of middle managers’ action-readiness profiles.

Research limitations/implications

This study has limitations that suggest directions for future research. Firstly, while qualitative methods offer valuable insights, they lack the generalizability of quantitative approaches. Secondly, as this study is limited to France, there is a need for similar research in other regions to understand cultural variations in middle managers’ interactions with RBMs.

Practical implications

The study identifies three levers to accelerate RBM implementation: introducing collaborative instances, developing strategies to enhance middle managers’ action readiness and ensuring an appropriate alignment between middle managers’ profiles and the demands of RBM transitions.

Originality/value

The study contributes novel insights into the challenges faced by companies in innovating their business model by taking a regenerative approach.
From regrets to returns: how interaction quality and store image shape store revisit intentions
Authors: Waqas Muhammad , Khan Muhammad Ali , Waseem Muhammad Adnan , Wajid Nauman
Published: December 2024

Purpose

Given the lack of understanding surrounding search regret, this study aims to draw on the regret regulatory theory to investigate the outcomes of search regret and effective strategies to reduce its adverse effects.

Design/methodology/approach

Using time-lagged data from 331 salespeople-customers dyads, this study investigates the connection between search regret, store image, interaction quality, and store revisit intentions.

Findings

Customers develop negative perceptions of the store, subsequently reducing their intentions to revisit. Salespeople’s interaction quality can reduce the negative impact of search regret on store image and revisit intentions. Furthermore, store image serves as a mediator between search regret and revisit intentions.

Originality/value

This study marks the first attempt to investigate the store image and revisit intentions as outcomes of search regret and examines the moderating role of salespeople’s interaction quality in reducing the negative consequences of search regret.
How expanded servicescape shapes fitness center members' decision-making processes: a stimulus-organism-response (SOR) model perspective
Authors: Özgen Caner , Kim Euisoo , Köse Hüseyin , Balcı Velittin , Çevik Hüseyin
Published: December 2024

Purpose

The purpose of this research is to examine the holistic impact of expanded servicescape stimuli (physical, social, socio-symbolic, natural) on the decision-making processes (emotional, attitudinal, normative, and control) of fitness center members and consequently, the indirect effects on behavioral intentions (response) within the Stimulus-Organism-Response (SOR) model.

Design/methodology/approach

A total of 336 fitness center members were reached using the convenience sampling method. The fundamental methodological principles of structural equation modeling (SEM) were followed to validate the proposed theoretical model and test the hypotheses.

Findings

The results revealed that the holistic servicescape stimuli of fitness centers affect the emotional, normative, attitudinal, and control variables in the psychological decision-making processes of members, thereby influencing their intentions to maintain their fitness center memberships.

Originality/value

This study significantly advances the literature by empirically demonstrating the combined effects of expanded servicescape stimuli on the decision-making processes of fitness center customers. Thus, providing valuable insights for both academics and practitioners in environmental psychology and sports marketing.
How ethnic congruence affects authenticity and perceived taste of traditional foods
Authors: Kuo Yahui , Helm Sabrina
Published: December 2024

Purpose

Food taste is essential for customer satisfaction and loyalty with food products and services. This study examines how ethnic cues influence taste perceptions in the growing traditional food sector.

Design/methodology/approach

Two experiments were conducted among students, faculty and staff members of two Taiwanese universities. The first experiment manipulated congruence of three ethnic cues (chef, wait staff and atmosphere) in an ethnic food setting, the second manipulated local identity salience and cue congruence for chefs in a local traditional food setting.

Findings

Ethnic congruities between food and chefs, wait staff and atmospherics increase perceived taste of traditional dishes, mediated by perceptions of authenticity and enhanced by consumer cosmopolitanism. In local traditional food settings, the indirect effect of ethnic congruence was found only when subjects perceived strong local identity. Cosmopolitanism played a negative role in the local traditional food setting.

Practical implications

The findings of this research provide insights into the potential taste management for both ethnic and local traditional food products and services and aid in the development of marketing strategies based on ethnic cues.

Originality/value

This research extends understanding of accessibility-diagnosticity theory to food judgments, empirically testing the implicit theory that ethnic food presented with ethnically congruent cues tastes better. To our knowledge, this is the first investigation distinguishing the different effects of ethnic cues on actual perceived taste for unfamiliar ethnic food and familiar local traditional food.
Understanding the reader demographics of an emerging online reading platform, Webtoon

Purpose

The current study investigates the reader demographics, appeals and reading motivations of Webtoon, a born-digital emerging multimedia reading platform that is widely available via mobile applications. This study aims to contribute to existing reader studies by exploring a novel reading platform in order to create future recommendation services.

Design/methodology/approach

An online survey was distributed, targeting Webtoon readers 18 years old or older. Descriptive and exploratory statistical analyses based on 1,117 valid survey responses were conducted to better understand the readers of Webtoon.

Findings

Seventy-six percent of Webtoon readers fall into the 18–33 age range, indicating the medium’s popularity among young adult readers. Among 14 appeal elements identified, Webtoon-specific appeals include visual/artistic style, sound and interactivity, time commitment, user-friendliness, and cost and price. Frequently selected Webtoon reading motivations include relaxation, changing one’s emotional state, escapism and achieving new experiences. Lastly, a cluster analysis yielded six distinctive Webtoon reader profiles: Habitual readers, emotionally-responsive readers, occasional readers, convenience-seeking readers, socially aware readers and Webtoon expert readers.

Originality/value

The current study adopts a persona concept from user experience research to suggest a way to understand Webtoon readers and improve recommendation services, a unique approach in reader studies. It aims to understand Webtoon readers from readers’ advisory and media studies perspectives, bridging two areas.
Corporate governance and liquidity creation in a duality banking system
Authors: Wardhani Nurhastuty , Faff Robert , Liu Lewis
Published: December 2024

Purpose

This study aims to investigate the factors influencing liquidity creation in banks, particularly focusing on the role of bank governance. Using a unique panel data set, it compares Islamic and conventional banks to discern governance’s impact on liquidity creation, offering insights for policymakers and bank managers.

Design/methodology/approach

Quantitative analysis is used on a panel data set to assess liquidity creation determinants in banks. A governance index is constructed, analyzing metrics such as risk management, audit committee effectiveness and Shariah board presence. Regression models identify significant relationships between governance factors and liquidity creation.

Findings

This study reveals a positive relationship between governance index and liquidity creation, especially in banks with better performance, higher credit risk, smaller size and lower equity, particularly in low-inflation environments. Specific governance practices significantly impact liquidity creation, alongside a positive relationship with Tier1 ratio, supporting the risk absorption hypothesis.

Originality/value

This research offers empirical evidence on the relationship between bank governance and liquidity creation, highlighting its significance for both Islamic and conventional banks. It provides valuable insights for policymakers and bank managers aiming to enhance banking sector stability and efficiency.
Narrative review on talent management: evaluating two decades and exploring future research directions
Authors: Abid Kousay , Polo Federica
Published: December 2024

Purpose

This article provides a comprehensive, critical examination of talent management (TM) literature through a narrative review spanning the past two decades. It explores the evolving TM landscape, offering a holistic view of its development and insights on global TM, global mobility and related theories. The goal is to enhance understanding of TM’s evolution and recommend future research directions grounded in contemporary theoretical frameworks.

Design/methodology/approach

A rigorous screening process produced a sample of 95 peer-reviewed articles (2004–2024) from Q1 and Q2 journals, selected for their theoretical and empirical contributions. Strict inclusion criteria ensured relevance, focusing on academic discourse. A thematic analysis traced key themes and TM’s evolution.

Findings

The synthesis identified six historical contexts and three narrative questions, addressing the standardization versus contextualization debate to frame TM’s evolution. Findings reveal a progression from early concepts to a mature, theory-driven field. Three research perspectives are proposed to guide TM toward balanced, contemporary approaches. Global mobility highlights the need for context-specific strategies, while integrating global and critical perspectives underscores contextualizing TM practices to diverse organizational and national contexts. This ensures inclusivity, equity and actionable insights for practitioners.

Originality/value

This narrative review provides a fresh perspective by tracing TM’s evolution through a historical lens, revealing trends and dynamics often missed in systematic reviews. It integrates the standardization vs. contextualization debate with dynamic capabilities and institutional theory, positioning TM as an agile, context-specific process adaptable in rapidly changing global environments.
Balancing act: exploring the mediating role of work–life balance on improving work engagement through organisational support
Authors: Andrlić Berislav , Ali Thasni , Ramanathan Hareesh N.
Published: December 2024

Purpose

The purpose of this paper is to investigate the mediating effect of work–life balance on the relationship between organisational support and work engagement. This research is based on the JD-R theory.

Design/methodology/approach

This study used a cross-sectional research design wherein both descriptive and explanatory approaches were used. This study uses a survey method and a structured questionnaire to collect data from IT women employees in Kerala. A regression analysis is used to measure the direct effects of the hypothesised relationships. Sobel’s test was used to measure the indirect effects of the hypothesised relationship.

Findings

Organisational support is found to foster work–life balance and work engagement. Work–life balance fully mediates the relationship between organisational support and work engagement.

Originality/value

This study attempts to integrate two streams of research (work–life balance and work engagement), which, despite being similar in focus, have been developed independently. This is one of the first studies to incorporate access to, utilisation and perceived future use of these practices in a single study. It also adds to the literature by investigating antecedents of work engagement and analysing it as a mediator between organisational support and work engagement, which has been highlighted as a gap in the literature.
Research on leakage characteristics of labyrinth seal based on air-oil two-phase flow
Authors: Li Yunfeng , Li Ruoxuan , Tian Ao , Xu Xinming , Zhang Hang
Published: December 2024

Purpose

This paper aims to study the influence of different seal structure parameters and working conditions on the air-oil two-phase flow characteristics and leakage characteristics of the seal cavity in the bearing cavity of the aero-engine spindle bearing tester.

Design/methodology/approach

In this paper, the VOF method and RNG k-ε turbulence model are used to explore the flow characteristics and leakage characteristics of the labyrinth seal cavity of an aero-engine spindle bearing tester under the condition of air-oil two-phase flow.

Findings

The distribution of the lubricating oil is related to the sealing clearance and the air-oil ratio. The amount of oil leakage increases with increasing of sealing chamber clearance, air-oil ratio and inlet velocity and decreases with increasing curvature and speed. The amount of air leakage increases with sealing clearance and inlet velocity.

Originality/value

In comparison to the pure air-phase flow field, the air-oil two-phase flow field can more accurately simulate the lubricating oil flow in the sealing chamber.
