Authors: Al Shaer Aisha Saif , Jabeen Fauzia , Jose Saju , Farouk Sherine 
Published: May 2023

PurposeDrawing on cultural intelligence and social exchange theories, this study examines cultural intelligence and its effects on proactive service performance and the mediating role of leader's collaborative nature and the moderating role of cultural training and emotional labor, particularly deep acting and surface acting, in the relationship between cultural intelligence and proactive service performance.Design/methodology/approachThe study sample comprised 510 healthcare practitioners. Structural equation modeling was used to examine the hypotheses.FindingsThe results show that cultural intelligence positively influences proactive service performance. Additionally, leadership's collaborative nature influences proactive service performance. The moderating effect of cultural training and deep acting positively influences the relationship between cultural intelligence and proactive service performance. In contrast, surface acting reveals a reverse effect, thus exhibiting a positive effect on this relationship.Research limitations/implicationsThese findings suggest that public healthcare organizations should pay more attention in improving deep acting, cultural training and leadership's collaborative nature for optimal service performance.Originality/valueThe novelty of this study lies in its presentation of an integrated framework based on cultural intelligence and social exchange theories that can solve the contemporary challenges facing healthcare firms operating in emerging markets in integrating cultural intelligence and service performance.

Published: May 2023

PurposeThe basic purpose of this study is to increase the installation rate of mobile games and their life cycle. Little research has been conducted into the competitive market of mobile games and word-of-mouth (WOM), advertisement and quality simultaneously. In this paper, the authors aim to assist developers with a better understanding of how to invest in the game industry.Design/methodology/approachThe primitive modeling has been made based on the Bass diffusion model and its extensions using features related to the game industry. Modeling and simulation have been performed using the system dynamics method.FindingsThe results show that if game developers only focus on advertising at the introduction of the game to the market, and neglect quality features, uninstall rate of adopters increases and the game life cycle decreases. And if developers only focus on the quality improvement of the game, and ignore advertisement, they couldn't create enough WOM and thus game installation wouldn't grow enough to create revenue. Furthermore, as long as the pleasure of the game is high for its adopters, developers shouldn't give up on investing in advertising to create even higher WOM. And also in communities with higher levels of variety-seeking among game players, quality is important at the start and advertisement is vital in the following steps of the game life cycle. And if the contact rate among people is high, developers could focus on quality more than the advertisement.Originality/valueEven though WOM in mobile game installation is crucial, fewer studies have been done in this area and they only address the problem using qualitative or statistical methods. The quantitative system dynamics approach based on the Bass diffusion model, used in this research, fixes the shortcomings of the previous studies. Moreover, due to serious competition in the mobile game industry, only those developers can remain in the market who can predict the future trend of the game market. Furthermore, game development is a creative process and its key factors include engaging the gamers and monetizing.

Purpose
This study aims to develop a hierarchical model that uncovers the relationships between challenges confronting Africa's organ transplant supply chain systems.

Design/methodology/approach
Eleven challenges (variables) were identified after a comprehensive review of the existing literature. The contextual interactions among these variables were analysed from the perspectives of health-care stakeholders in two sub-Saharan Africa (SSA) countries (Nigeria and Uganda), using Delphi-interpretive structural modelling-cross-impact matrix multiplication applied to classification (MICMAC) techniques.

Findings
The findings reveal that weak regulatory frameworks, insufficient information systems and a lack of necessary skills make it challenging for critical actors to perform the tasks effectively. The interaction effects of these challenges weaken organ supply chains and make it less efficient, giving rise to negative externalities such as black markets for donated organs and organ tourism/trafficking.

Research limitations/implications
This paper establishes a solid foundation for a critical topic that could significantly impact human health and life once the government or non-profit ecosystem matures. The MICMAC analysis in this paper provides a methodological approach for future studies wishing to further develop the organ supply chain structural models.

Practical implications
The study provides valuable insights for experts and policymakers on where to prioritise efforts in designing interventions to strengthen organ transplantation supply chains in developing countries.

Originality/value
This study is one of the first to empirically examine the challenges of organ transplant supply chains from an SSA perspective, including theoretically grounded explanations from data collected in two developing countries.
How integrated store-service quality promotes omnichannel shoppers’ word-of-mouth behaviors: the moderating role of perceived relationship investment and the shopper’s perceived value
Authors: Natarajan Thamaraiselvan , Veera Raghavan Deepak Ramanan 
Published: May 2023

PurposeThe post-purchase behavioral responses of omnichannel shoppers, who mainly rely on physical stores (acknowledged as a crucial channel in providing a seamless shopping experience and fulfilling the dynamic needs of the shoppers), are still understudied. The purpose of this paper is to examine how integrated store service quality (ISSQ) can contribute to a more optimal shopping experience (cognitive, affective and relational) and have a subsequent impact on shoppers’ psychological ownership toward the store, resulting in the generation of (face-to-face, online and social media) word of mouth (WOM).Design/methodology/approachThe research is descriptive, quantitative and cross-sectional investigation. A purposive sampling technique was used for selecting the study respondents. The data were collected from 786 Indian omnichannel shoppers using a validated self-administered questionnaire. The proposed conceptual model was tested using partial least squares structural equation modeling.FindingsThe results indicate that all three dimensions of omnichannel customer experience (cognitive, affective and relational) positively mediate the relationship between ISSQ and psychological ownership, subsequently impacting all three WOM behaviors of omnichannel shoppers (face-to-face, online store and social media). The customer’s perceived value with the store and their perceived retailer relationship investment significantly moderated the relationship between ISSQ and different WOM behaviors (face-to-face, online store and social media). This research also demonstrated the direct impact of ISSQ on WOM and the indirect impact through different customer experience dimensions and psychological ownership.Research limitations/implicationsThe sample used in the study was not probabilistic and, therefore, presents limitations for the possibility of generalizing the results. The study was performed in a cross-sectional methodology in the Indian context; there is a need for longitudinal investigation.Originality/valueThis study addresses the need to investigate different dimensions of omnichannel customer experience that might influence various post-purchase behavioral responses. This study is the first to show that ISSQ might affect omnichannel shoppers' online, offline and social media word-of-mouth behaviors through different customer experience dimensions and the customer’s sense of belongingness to the store. The moderating effect of customer perceived value with the retailer and their perception of retailers’ investment in a relationship on proposed hypotheses was also tested to give managerial recommendations.

Published: May 2023

AbstractTechnological change co‐determines agri‐environmental performance and farm structural transformation. Meaningful impact assessment of related policies can be derived from farm‐level models that are rich in technology details and environmental indicators, integrated with agent‐based models capturing dynamic farm interaction. However, such integration faces considerable challenges affecting model development, debugging and computational demands in application. Surrogate modelling using deep learning techniques can facilitate such integration for simulations with broad regional coverage. We develop surrogates of the farm model FarmDyn using different architectures of neural networks. Our specifically designed evaluation metrics allow practitioners to assess trade‐offs among model fit, inference time and data requirements. All tested neural networks achieve a high fit but differ substantially in inference time. The Multilayer Perceptron shows almost top performance in all criteria but saves strongly on inference time compared to a Bi‐directional Long Short Term Memory.

Published: May 2023

AbstractHepatocellular carcinoma (HCC) is a common cancer and is frequently diagnosed at a late and unresectable stage with limited effective treatment options. Here, we present the fifth reported case of a 77 year‐old male with metastatic HCC presenting as a symptomatic superior sulcus lung tumor and discuss the genomic profile of this rare presentation of HCC for the first time, which included multiple classic mutations in HCC such as TERT, TP53, and WNT/β‐catenin signaling as well as in the DNA repair gene ATM. The patient was treated with palliative radiotherapy to the Pancoast tumor followed by atezolizumab plus bevacizumab and passed away 6 months after diagnosis. This rare case highlights the need for effective treatment in aggressive and unresectable HCC and the utility of early genomic studies to allow for targeted therapy such as poly (ADP‐ribose) polymerase (PARP)‐inhibitors.
The contribution of epidemiology to the understanding of neurodevelopmental disabilities
Authors: Paneth Nigel 
Published: May 2023

AbstractEpidemiological approaches have played an important role in creating better understanding of developmental disabilities by delineating their frequency in populations and changes in their frequency over time, by identifying etiological factors, and by documenting pathways to prevention. Both cerebral palsy (CP) and mild intellectual disability are declining in frequency in high‐income countries. The diagnosis of autism spectrum disorder has increased in recent decades, but much of this increase is a result of changing approaches to ascertainment and recording. Epidemiological studies have found that most CP is not of birth‐asphyxial origin, that most febrile seizures do not pose a major risk for epilepsy, and that folic acid deficiency may contribute to developmental disabilities apart from its effect on neural tube defects. Epidemiological research has shown that an important fraction of neural tube defects and virtually all cases of Reye syndrome are preventable, and recent trials have shown ways to prevent CP. Early psychoeducational interventions in children at risk for mild intellectual disability are an effective and valuable societal investment. Very large population‐based studies starting in pregnancy have been launched in Norway, Denmark, and Japan in recent years and these and other population studies promise to continue the epidemiological contribution to a better understanding of developmental disabilities.
Right ventricular hypertrophy in apical hypertrophic cardiomyopathy
Authors: Mihos Christos G. , Escolar Esteban , Fernandez Rafle 
Published: May 2023

AbstractBackgroundRight ventricular hypertrophy (RVH+) in hypertrophic cardiomyopathy occurs in one third of patients, however, outcomes in apical hypertrophic cardiomyopathy (ApHCM) have not been described. We hypothesized that RVH+ in ApHCM is associated with more ventricular remodeling and dysfunction, and increased adverse events when compared with those without RVH (RVH−).MethodsNinety‐one ApHCM patients were retrospectively analyzed using 2D and speckle‐tracking echocardiography (64 ± 16 years old, 43% female). RVH+ was defined as wall thickness >5 mm and was present in 23 (25%). Ventricular mechanics were characterized by global longitudinal strain (GLS), RV free wall strain, and myocardial work.ResultsNew York Heart Association functional class > II, atrial fibrillation, and prior stroke were more prevalent in RVH+. Left ventricular (LV) size and ejection fraction were similar between groups, with greater septal (17 vs. 14 mm, p = .001) and apical (20 vs. 18 mm, p = .04) wall thickness in RVH+. When compared with RVH− patients, RVH+ had worse LV GLS (−8.6 vs. −12.8%), global work index (820 vs. 1172 mmHg%) (both p < .001), and work efficiency (76 vs. 83%, p = .001), as well as RV GLS (−14 vs. −17.5%) and free wall strain (−17.3 vs. −21.3%) (both p = .02). At 3‐year follow‐up RVH+ had greater incidence of heart failure hospitalization compared with RVH− (35 vs. 7%, p = .003). RVH+ was associated with RV GLS (β = .2, p = .03), independent of clinical and echocardiographic variables.ConclusionsRVH+ patients with ApHCM have worse biventricular mechanics and myocardial work, and more heart failure hospitalization, as RVH− at mid‐term follow‐up.
Demographic disparities in dental school selection: An analysis of current UK practices

Published: May 2023

AbstractIntroductionSpecific social groups remain under‐represented within dentistry. While the University Clinical Aptitude Test (UCAT) aims to widen participation in under‐represented social groups, there is no evidence in dental education that this aim is being met.Materials and MethodsData over two admission cycles (2012 and 2013), including 3246 applicants to 10 UK dental schools, were analysed. Applicant and selected pools were compared to the UK population. Multiple logistic regression was used to investigate the association between demographic variables and UCAT and receiving an offer of a place at dental school.ResultsOver‐representation of Female, Asian, least deprived and grammar school groups were found in applicant and selected pools compared with the UK population. White ethnic applicants were significantly more selected than Black (OR 0.25), Asian (OR 0.57) and Mixed (OR 0.80) ethnicities, while least deprived applicants were significantly more selected than most deprived (OR 0.59). Grammar school education increased odds of selection by 1.8 when compared to state school. The addition of UCAT to the model for applicants reduced ethnic disparities but led to disparities between other groups.ConclusionCurrent widening participation practices focus on attracting applicants from lower socio‐economic groups. However, this study showed that ethnicity, sex and educational background biases also affect demographic diversity in dentistry.The UCAT shows promise in levelling the playing field; however, widening access measures will only succeed if selection committees radically change selection processes to address the systemic biases, enabling the dentists of tomorrow to represent the society they serve.

Published: May 2023

AbstractBackground and purposeMeasuring health‐related quality of life (QOL) is vital for understanding the disease impact, but the complex relationship between clinical parameters and QOL remains unclear. The objective was to determine the demographic and clinical factors that influence the QOL in adults with inherited and acquired myopathies.MethodsThe study was of cross‐sectional design. Detailed demographic and clinical details were collected. Patients answered Neuro‐QOL and Patient‐Reported Outcomes Measurement Information System short‐form questionnaires.ResultsData was collected from 100 consecutive in‐person patient visits. Mean age of the cohort was 49.5 ± 20.1 (18–85) years, and the majority were male (53, 53%). Bivariate analysis between the various demographic and clinical features with the QOL scales revealed single simple question (SSQ), handgrip strength, Medical Research Council (MRC) sum score, female gender, and age to be nonuniformly associated with the QOL scales. There was no difference between inherited and acquired myopathies for any of the QOL scores, except for the poorer lower limb function domain in inherited myopathies (36.7 ± 7.3 vs. 40.9 ± 11.2, p = 0.049). Linear regression models revealed lower SSQ, lower handgrip strength, and lower MRC sum score to independently predict poor QOL.ConclusionsHandgrip strength and SSQ serve as novel predictors of QOL in myopathies. Handgrip strength has a significant impact on physical, mental, and social domains and deserves special attention with respect to rehabilitation. SSQ correlates well with QOL and can be employed as a quick and global assessment of a patient's well‐being. Differences in QOL scores between patients with inherited and acquired myopathies were minimal.
Policy diffusion, policy transfer, and policy mobilities revisited: A call for more interdisciplinary approaches in human geography
Authors: Haupt Wolfgang 
Published: May 2023

AbstractGeographers and urban studies scholars tend to rely on policy mobilities approaches to explain processes of policy spread, whereas political scientists and public policy scholars usually draw on either policy diffusion or policy transfer. I challenge this widespread scholarly practice of selecting approaches based on the association with a certain discipline. Instead, first and foremost, the specific research aim(s) and question(s) should shape the choice of theoretical lens. Analytical or policy outcome‐oriented studies should rely on policy diffusion and policy transfer, while a policy mobilities approach is best suited for more (policy) critical analysis. The approaches can also complement each other to a certain degree. Analytical and policy outcome‐oriented approaches need a stronger critical perspective while policy mobilities scholars need to underpin their critique with constructive suggestions on how to improve established practices.

ObjectiveTo identify biomarkers associated with the effectiveness of ipilimumab plus nivolumab against advanced metastatic renal cell carcinoma.MethodsWe retrospectively analyzed the data of 75 patients treated with ipilimumab plus nivolumab at seven hospitals between August 2018 and April 2021. Prognostic biomarkers were assessed prior to initiating treatment with ipilimumab plus nivolumab. Median overall survival and progression‐free survival were examined using the Kaplan–Meier method. Univariate and multivariate analyses were performed to identify predictors of disease progression. The International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk factors most important for predicting disease progression were determined using classification and regression tree analysis.ResultsMedian overall survival and progression‐free survival were longer in the intermediate IMDC risk group than in the poor IMDC risk group (overall: not reached vs. 18.3 months; progression‐free: not reached vs. 13.5 months). The multivariate analysis identified poor IMDC risk as a risk factor for disease progression (hazard ratio 2.61, 95% confidence interval: 1.05–6.51). Based on the results of the classification and regression tree analysis, the cohort was divided into non‐anemia, anemia + neutro‐Low, and anemia + neutro‐High groups. Median overall survival and progression‐free survival were longer in the non‐anemia and anemia + neutro‐Low groups than in the anemia + neutro‐High group (overall: not reached vs. 29.3 months vs. 4.3 months: progression‐free: not reached vs. 29.0 months vs. 3.9 months).ConclusionHemoglobin and neutrophil levels may represent crucial biomarkers for predicting the effectiveness of ipilimumab plus nivolumab therapy in patients with renal cell carcinoma.
