Revisiting consumer loyalty: luxury brand extension into restaurants and cafés
Authors: Kim Sanghee , Cuevas Leslie , Chang Hyo Jung (Julie) 
Published: December 2024

PurposeWith luxury brands extending into restaurants and cafés, the definition of luxury consumption no longer refers to tangible products alone but to intangible and authentic experiences as well. Drawing on the Stimulus–Organism–Response framework (SOR) and the costly signalling theory, this study explores the sequential mechanisms of experiences in luxury brands’ restaurants and cafés among Korean and US consumers.Design/methodology/approachThis study distributed online surveys in South Korea and the US and recruited 419 participants (South Korea = 210; US = 209). PLS-SEM and multigroup analysis were used to test the hypotheses.FindingsPerceived quality influenced perceived luxury values positively and led to consumers’ loyalty to both the parent brand (i.e. luxury fashion brand) and extended brand (i.e. luxury restaurants and cafés).Originality/valueLuxury brands seek to offer their consumers authentic and extraordinary experiences. By merging luxury fashion with gastronomy, these brands can foster synergistic long-term relationships with consumers and enhance their brand equity in the global luxury market. Our results also demonstrated that such expansion contributes to competitive advantages in luxury fashion retailing by increasing their intangible values in addition to their parent luxury fashion brands. Further, in the context of globalisation, this research provides insights into how luxury retailers’ novel approach to the F&B sector can enhance consumers’ loyalty across different cultures and strengthen their global luxury retail strategy.
Mini-programs as substitution or promotion? Deciphering the cross-channel impact on e-marketplace purchases
Authors: Wang Juan , Fang Jie , Wang Yuting 
Published: December 2024

PurposeThis study disentangles the impact of consumers’ adoption of mini-program channels on social media on their purchase behavior in e-marketplaces from a multichannel retailer’s perspective and examines the moderating roles of two types of brand messages (informational and transformational messages).Design/methodology/approachBased on 2,204 transaction records from a Chinese multichannel retailer, this study used a Poisson regression model with fixed effects for empirical testing. The case of the WeChat mini-program in China was employed.FindingsAdopting mini-program channels on social media reduces consumers’ purchase frequency but increases their purchase breadth in e-marketplaces. Moreover, informational messages worsen the negative effect of mini-program channel use on purchase frequency. In contrast, transformational messages reduce the negative effect of mini-program channel use on purchase frequency and amplify its positive effect on purchase breadth.Practical implicationsManagers can effectively leverage mini-programs to widen the range of consumers’ product purchases in e-marketplaces and the intensity of transformation messages posted within mini-programs to alleviate their negative impact on purchase frequency in e-marketplaces.Originality/valuePrevious studies only focus on the intrachannel impact of mini-program channels; however, this study highlights their cross-channel impact. Its findings underscore the dual role of mini-program channel use in e-marketplaces. Additionally, the nuanced moderating effects of informational and transformational messages enrich our understanding of mini-program channels on social media. Moreover, a substitution framework is utilized to understand the cross-channel effects generated by mini-program channels, demonstrating the applicability and generalizability of the framework in a new context.
Self-service technologies in retail stores: how phygital retailing creates customer value and drives choice confidence
Authors: Stan Valentina , Baltas George , Pourot-Feenstra Florence 
Published: December 2024

PurposeThe purpose of this empirical study is to consider the interaction of self-service technologies (SSTs) with retail customers, exploring how retail customers perceive SST value and how this value affects their choice confidence when shopping.Design/methodology/approachWe carried out a large shopper survey in collaboration with six French mass retailers. Digital kiosks and interactive tablets were the focal SSTs. Partial least squares-path modelling (PLS-PM) was used to test our cost‒benefit conceptual framework and the corresponding research hypotheses. Furthermore, through multigroup comparison analysis, we tested the moderating effect of customers’ subjective knowledge of the product category.FindingsFunctional and interactive benefits/costs arising from SST usage determine customer perceived value. The key notion of perceived SST value implies that people make favourable cost‒benefit tradeoffs. Customer choice confidence is positively affected by perceived SST value. Customer product category knowledge plays a key role as a moderator of human–SST interactions in phygital retail settings.Originality/valueThis paper is concerned with the role of SST in creating phygital experiences and delivering value to retail customers. This is a first attempt at examining how perceived SST value affects customer choice confidence and what role customer product category knowledge plays.

Influence of brand community social responsibility on consumer citizenship behaviors: mediating role of collective self esteem
Authors: Guo Xiaoxuan , He Yuan , Wang Yucheng , Zhou Zhimin 
Published: December 2024

Purpose
Drawing from social contagion theory, this study aims to clarify whether consumers become motivated to help a brand and its community when observing other members contributing to society. The authors also analyzed the boundary conditions and mechanisms of this process.

Design/methodology/approach
A mixed-method approach was used to test hypotheses. Study 1 collected survey data from Chinese automobile brand communities, which were analyzed by using partial least squares structural equation modeling. Study 2 conducted an experiment with a fictional Chinese smartphone brand community.

Findings
Results showed that brand community social responsibility influenced brand community citizenship behavior but did not directly influence brand citizenship behavior. Collective self-esteem respectively mediated the relationships between brand community social responsibility and both brand community citizenship behavior and brand citizenship behavior. Additionally, a sequential mediation mechanism was identified, where collective self-esteem and brand community citizenship behavior functioned as the first and second mediators. Furthermore, membership duration positively moderated the relationship between brand community social responsibility and collective self-esteem and moderated the mediation effects.

Practical implications
Brand community managers should conduct various social responsibility activities to elicit community and brand citizenship behaviors by cultivating ethical awareness. These activities should be tailored to the membership duration.

Originality/value
To the best of the authors’ knowledge, this study is the first to explore how brand community social responsibility cultivates community and brand citizenship behavior. It is also based on social contagion theory to demonstrate the sequential mediation mechanism.

Published: December 2024

AbstractComprehensive studies of the genetic profiles of cutaneous squamous cell carcinoma (cSCC) in Japanese patients have been lacking, although an understanding of these profiles is crucial for improving treatment outcomes. Since 2019, comprehensive genomic profiling (CGP) has been covered by Japan's health insurance, and the resulting data have been compiled into a comprehensive database by the country's Center for Cancer Genomics and Advanced Therapeutics (C‐CAT). In this retrospective study, we used CGP data from the C‐CAT database to analyze genomic characteristics of cSCC in Japanese patients. The patients' clinical and genomic data, including the chemotherapy regimens, tumor mutational burden (TMB), and survival status, were obtained. We analyzed the cases of 152 patients, with only those evaluated by the FoundationOne® CDx included for accuracy. Among the 152 patients, the most common gene oncogenic alterations were observed in TP53 (67%), CDKN2A (54%), TERT (49%), CDKN2B (33%), and NOTCH1 (18%). TMB‐high (≥10 mut/Mb) was observed in 27% (n = 41) of the patients, with a median age of 75 years for this group. TMB‐low (<10 mut/Mb) was observed in 73% (n = 111) of the patients; their median age was 67 years.
Sense and Action: Organizational Reactions in Extreme Crisis: A Survey With Brazilian Executives
Authors: Milagres Rosileia , Bernardes Maria Elisa Brandão , de Carvalho Rodrigo Baroni 
Published: December 2024

ABSTRACTThe objective of the paper is to analyse the actors' perception regarding how organizational actors lead the reaction of their companies to crises, changing or not their routines accordingly. The paper contributes to enlarging the understanding of crisis management by an original perspective of phenomenon evaluation based on the junction of two literature fields: sensemaking and routines, considering the organizational context that impacts crisis management. A survey of 128 company executives from different industries in Brazil was developed to identify how their companies dealt with the COVID‐19 crisis, considering sensemaking, routines and the organizational context. The results unveiled a significant and positive influence of sensemaking and organizational context on the crisis reaction, but not on the deliberated mobilization of the routines, emphasizing improvisation and trial‐and‐error. The results reinforce fast sensemaking attitudes yielding direct implementation to test the new routines, correcting course of action promptly.

Published: December 2024

AbstractIndigenous fruits and vegetables can improve food security and biodiversity. However, their use is hindered by perishability, seasonal availability, cooking losses, lack of nutritional composition data, and connections to low socioeconomic status. This study aimed to process cowpea leaves into powder and determine the effect of five home‐cooking methods on their protein, functional, physicochemical, and heavy metal profiles. Cowpea leaves were boiled, blanched, steamed, sous‐vide cooked, and stir‐fried, at 5, 10, and 15 min before dehydration at 60°C. Cowpea leaves contain protein up to 20 g/100 g. The leaves are rich in calcium, potassium, and zinc, providing up to 70% of the adult recommended dietary allowance for calcium and potassium per 100 g of powder. Cowpea leaf powder exhibited good water/oil absorption and rehydration capacities. Sous‐vide and steamed cowpea leaves provided an overall superior nutritional profile (p ≤ 0.05). Heavy metals in the cowpea leaf powders were below the WHO permissible limits except for aluminum and high arsenic levels. This study demonstrated that cowpea leaf powders could be potentially incorporated into foods to improve functional properties and nutrient intake.

Published: December 2024

AbstractThe critical role of some RAB family members in oocyte meiosis has been extensively studied, but their role in oocyte aging remains poorly understood. Here, we report that the vesicle trafficking regulator, RAB9 GTPase, is essential for oocyte meiosis and aging in humans and mice. RAB9 was mainly located at the meiotic spindle periphery and cortex during oocyte meiosis. In humans and mice, we found that the RAB9 protein level were significantly increased in old oocytes. Age‐related accumulation of RAB9 inhibits first polar body extrusion and reduces the developmental potential of oocytes. Further studies showed that increased Rab9 disrupts spindle formation and chromosome alignment. In addition, Rab9 overexpression disrupts the actin cap formation and reduces the cortical actin levels. Mechanically, Rab9‐OE increases ROS levels, decreases mitochondrial membrane potential, ATP content and the mtDNA/nDNA ratio. Further studies showed that Rab9‐OE activates the PINK1‐PARKIN mitophagy pathway. Importantly, we found that reducing RAB9 protein expression in old oocytes could partially improve the rate of old oocyte maturation, ameliorate the accumulation of age‐related ROS levels and spindle abnormalities, and partially rescue ATP levels, mtDNA/nDNA ratio, and PINK1 and PARKIN expression. In conclusion, our results suggest that RAB9 is required to maintain the balance between mitochondrial function and meiosis, and that reducing RAB9 expression is a potential strategy to ameliorate age‐related deterioration of oocyte quality.

Published: December 2024

SummaryIntroductionRetrospective studies suggest that inhalational volatile anaesthetic agents may contribute to an increased risk of metastasis and reduction in survival rates when used during cancer surgery. This relationship may vary between cancer types due to different tumour biology and differences in surgical procedures. This study aimed to investigate the relationship between the type of anaesthetic used for maintenance of anaesthesia (propofol or inhalational volatile anaesthetic agent) and survival in patients with stage 1–3 colorectal cancer who underwent resection surgery under general anaesthesia in Sweden between 2014 and 2019.MethodsWe identified patients from the Swedish Colorectal Cancer Registry. Their data, including cancer characteristics and adjuvant treatment, were then merged with information from the Swedish Peri‐operative Registry. The primary outcome was overall survival, with disease‐free survival as a secondary outcome.ResultsOf the 11,598 patients included, 8161 had colon cancer and 3437 had rectal cancer. General anaesthesia was maintained with propofol in 2346 (20%) patients, while 9252 (80%) received an inhalational volatile anaesthetic agent. In the unmatched cohort, patients who had general anaesthesia maintained with propofol for colon cancer surgery showed improved survival compared with those receiving an inhalational volatile anaesthetic agent (hazard ratio 0.83, 95%CI 0.72–0.95, p = 0.008). After 1:2 propensity score matching, we observed no significant difference in survival rates in this group (hazard ratio 0.89, 95%CI 0.76–1.04, p = 0.127). In the rectal cancer group, there was no difference in survival in either the unmatched cohort (hazard ratio 0.83, 95%CI 0.65–1.08, p = 0.166) or after propensity score matching (hazard ratio 0.95, 95%CI 0.71–1.25, p = 0.702). There was no significant difference in disease‐free survival in either type of cancer.DiscussionWe found no association between the choice of agent for maintenance of anaesthesia and long‐term survival outcomes in patients with colorectal cancer.

AimsThe potential of mechanistic biomarkers to improve prediction of drug‐induced liver injury (DILI) and hepatic regeneration is widely acknowledged. We sought to determine reference intervals for new biomarkers of DILI and regeneration, as well as to characterize their natural variability and impact of diurnal variation.MethodsSerum samples from 227 healthy volunteers were recruited as part of a cross‐sectional study; of these, 25 subjects had weekly serial sampling over 3 weeks, while 23 had intensive blood sampling over a 24h period. Alanine aminotransferase (ALT), MicroRNA‐122 (miR‐122), High Mobility Group Box‐1 (HMGB1), total Keratin‐18 (K18), caspase‐cleaved Keratin‐18 (ccK18), Glutamate Dehydrogenase (GLDH) and Macrophage Colony‐Stimulating Factor‐1 (CSF‐1) were assayed.ResultsReference intervals were established for each biomarker based on the 97.5% quantile (90% CI) following the assessment of fixed effects in univariate and multivariable models. Intra‐individual variability was found to be non‐significant, and there was no significant impact of diurnal variation.ConclusionReference intervals for novel DILI biomarkers have been described. An upper limit of a reference range might represent the most appropriate mechanism to utilize these data. These data can now be used to interpret data from exploratory clinical DILI studies and to assist their further qualification as required by regulatory authorities.
A ranking forced choice diagnostic classification model for psychological assessment using forced choice questionnaires

Published: December 2024

AbstractThe diagnostic classification model (DCM) has been widely utilized in non‐cognitive tests, offering diagnostic information on latent attributes. However, the model's reliance on single‐stimulus (SS) items may lead to response biases (e.g., social desirability), jeopardizing the psychometric properties. As an alternative to SS scales, forced choice questionnaires (FCQ) can effectively control response biases. The combination of FCQs and the DCM not only circumvents response bias but also yields fine‐grained diagnostic information on latent attributes. To the best of our knowledge, only one study (Huang, Educ. Psychol. Meas., 83, 2022, 146) has explored this topic and developed a DCM for forced choice (FC) items. However, the existing model has limitations in terms of its modelling assumption, the FC format and the number of attributes measured by statement. To address these limitations, this study proposes a ranking FC‐DCM that (1) adopts a generalized assumption, (2) covers all FC formats and (3) eases the limitation on the number of attributes measured by each statement. The simulation study demonstrated that the proposed model exhibited satisfactory person and item parameter recovery under all conditions. This study provided an illustrative example by developing an FC version questionnaire to further explore the applications and advantages of the proposed model in real‐world settings.
Labor Outcomes After Employer‐Provided Training: Evidence from the Understanding Society Survey
Authors: Ullah Akbar 
Published: December 2024

ABSTRACTA simple two‐period model is developed to show that employer‐provided training might increase workers' wages and incentives to work more paid and unpaid hours. These predictions are then tested using the United Kingdom Understanding Society Survey data. The empirical analysis suggests that individuals with at least one employer‐provided training incident work more paid and unpaid overtime compared with individuals without employer‐provided training. Training has significant positive and permanent effects on wages and the odds of workers being in a managerial role after training. Additionally, those with employer‐provided training have higher odds of job satisfaction. The unpaid working hours and job satisfaction effects of job training are not long‐lasting.

Published: December 2024

ABSTRACTChildren are the builders of the future, and their education is crucial for societal development. This study aims to identify and analyse the barriers that prevent marginalised communities from participating in educational activities and explore strategies for overcoming these obstacles. Focused on Pakistan, which has the second highest number of out‐of‐school (OOS) children globally according to UNICEF, this research utilises data from the Multiple Indicator Cluster Survey (MICS) Wave 6. Employing logistic regression and generalised structural equation modelling (GSEM), we investigate the impact of foundational skills, child disabilities, socioeconomic factors and regional differences on school attendance. The study particularly examines the role of financial assistance, including tuition fees and social transfers, in addressing the issue of out‐of‐school (OOS) children. The findings highlight the need for inclusive policies, adequate funding and enhanced foundational skills to improve school attendance and academic outcomes.
