CSR disclosure as a legitimation strategy: evidence from the football industry
Authors: Raimo Nicola , Vitolla Filippo , Nicolò Giuseppe , Tartaglia Polcini Paolo 
Published: April 2021

PurposeThe latest developments in the football industry, the commodification of sport, the excessive focus on profitability and the limited attention to social and environmental aspects have caused a legitimation crisis for football clubs. According to the legitimacy theory, the corporate social responsibility (CSR) disclosure represents a tool capable of allowing the construction or repair of legitimacy. This study, in line with this theory, aims to analyse the amount of CSR disclosure provided by football clubs and the determinants, related to visibility, of the level of information provided.Design/methodology/approachThis study uses a manual content analysis on the corporate websites of the 80 football clubs that qualified for the UEFA Champions League and UEFA Europa League group stages for the 2019–2020 year to measure the level of CSR disclosure and subsequently a regression analysis to examine the impact of visibility on the amount of information provided.FindingsResults reveal that football clubs still disclose relatively little information about sustainability issues, and that sports performance visibility, human capital visibility and social media visibility positively affect the amount of information that football clubs disclose.Originality/valueThis study extends the horizons of CSR disclosure to the football industry which is still little explored in the academic literature. Furthermore, it extends the scope of legitimacy theory, showing how CSR disclosure can be a means for football clubs to obtain or repair legitimacy. Furthermore, this study extends the list of determinants of the level of CSR disclosure, showing that visibility can influence the amount of CSR information.
“Stepping out of the ordinary”: exploring cross-cultural challenges of expatriates in the Kingdom of Saudi Arabia
Authors: Dousin Oscar , Sulong Rini Suryati 
Published: April 2021

Purpose
In the study of expatriation and expatriate adaptation, there are limited studies that focus on issues faced by expatriates working in foreign countries with very distinct cultures. This study aims to explore this idea through the experiences of western expatriates working in the Kingdom of Saudi Arabia (KSA). Two research questions were posed to examine the cross-cultural issues and challenges faced by expatriates in the KSA, as well as the role of cross-cultural training in expatriate adjustment.

Design/methodology/approach
The study was guided by an interpretivism paradigm through a qualitative method by using a semi-structured in-depth interview approach. Interviews were conducted among 12 expatriates from the USA and UK who are currently working in KSA.

Findings
A coding technique and theoretical thematic analysis was conducted to analyze the data. The results of this study highlighted three key themes that had a considerable influence on expatriates’ adjustment, in particular: culture shock, lack of pre-departure training and the demand for an extensive cross-cultural training.

Research limitations/implications
It is acknowledged that the existence of sub-cultures within the KSA would expose the respondents to varying cultural values within the community. Thus, future studies within a similar context should consider the influence of intra-cultural variations.

Originality/value
The findings of the study emphasized on the importance understanding the cultural gap between home and host country and the individual cultural awareness of the expatriate. It calls attention to the need for a tailored and extensive pre-departure, cross-cultural training and a collaborative effort between employees’ and managers to improve expatriates’ motivation and retention.
Mix design of high performance concrete with different mineral additions
Authors: Hadji Tarek , Guettala Salim , Quéneudec Michèle 
Published: April 2021

Purpose
The purpose of this paper is to present the modeling of statistical variation of experimental data using the design of experiments method to optimize the formulation of a high performance concrete (HPC) using materials that are locally available in Algeria. For this, two mineral additions (natural pozzolana and limestone filler [LF]) were used. Both additions are added by substitution of cement up to 25%. To better appreciate the effect of replacing a part of cement by natural pozzolana and LF and to optimize their combined effect on the characteristics of HPC, an effective analytical method is therefore needed to reach the required objective.

Design/methodology/approach
The experimental part of the study consisted of substituting a portion of cement by various proportions of these additions to assess their effects on the physico-mechanical characteristics of HPC. A mixture design with three factors and five levels was carried out. The JMP7 software was used to provide mathematical models for the statistical variation of measured values and to perform a statistical analysis. These models made it possible to show the contribution of the three factors and their interactions in the variation of the response.

Findings
The mixture design approach made it possible to visualize the influence of LF and pozzolanic filler (PF) on the physico-mechanical characteristics of HPC, the developed models present good correlation coefficients (R2 = 0.82) for all studied responses. The obtained results indicated that it is quite possible to substitute a part of cement with LF and PF in the formulation of a HPC. Thanks to the complementary effect between the two additions, the workability could be improved and the strengths drop could be avoided in the short, medium and long term. The optimization of mixture design factors based on the mathematical models was carried out to select the appropriate factors combinations; a good agreement between the experimental results and the predicted results was obtained.

Originality/value
The coefficient of PF in Cs28 model is closer to that of LF than in Cs7 model, thanks to the complementary effect between LF and PF at the age of 28 days. It was found that the optimal HPC14 concrete (10%LF–5%PF) provides the best compromise between the three responses. It is also worth noting that the use of these two local materials can reduce the manufacturing costs of HPC and reduce carbon dioxide emissions into the atmosphere. This can be an important economic and environmental alternative.
The interaction between gender and informal social networks: An East Asian perspective
Authors: Georgiadou Andri , Syed Jawad 
Published: April 2021

AbstractDespite the increasing attention to gender diversity management in recent decades, there is a dearth of studies that provide an East Asian perspective on this topic. We argue that informal social networks have a crucial role in macrosocial and organisational approaches to diversity, such as social attitudes and laws, which in turn may affect organisational routines and practices of diversity management. In this article, we develop a research framework that connects gender diversity approach across macrosocial and organisational levels of analysis. Responding to the call for contextual research, our focus in this article is on how gender diversity management in East Asia is affected by informal social networks at the macrosocial level, namely guanxi in China, yongo in South Korea, and jinmyaku in Japan. Our review posits informal social networks as salient in mediating the shape and effect of institutional mechanisms at the macrosocial level on diversity practices at the organisational level.

Published: April 2021

AbstractIntroductionIn 2016, low‐and‐middle income countries (LMICs) accounted for 79% of the global suicide deaths. In LMICs, vulnerable groups—women, sexual minorities and refugees, and internally displaced persons (IDPs)—are at high risk of suicidal ideation, attempts and deaths by suicide, but information for designing targeted interventions for them is fragmented and missing, making it difficult to address gaps in the existing system. This review highlights these gaps by mapping: (a) risk factors associated with suicides and suicidal behavior including challenges in implementing targeted programmes for vulnerable groups; and (b) recommendations for effective suicide prevention interventions and strategies in LMICs as documented in the literature.MethodsA descriptive mapping review of literature was conducted. Three electronic databases—PubMed, Google Scholar, and Refworld—were searched for specific keywords. The researchers mapped and reviewed 34 studies on suicide and suicide prevention across three main vulnerable groups.ResultsThis review highlighted the need for gender‐specific interventions for women and sexual minorities, addressing gender‐based discrimination, access to healthcare, abuse and violence, while for refugees and IDPs, critical concerns are monitoring and understanding suicidal behaviors and to address psychological and emotional responses to resettlement.ConclusionIn LMICs, specific and unique socio‐cultural and environmental factors may increase the risk of vulnerable groups to suicidal behaviors. In order to develop effective and comprehensive suicide prevention strategies, it is crucial to evaluate these differential risk factors and develop culturally appropriate and sensitive interventions and strategies.
‘It's not fair’: Custodial grandparents' access to services and supports in Australia
Authors: Fernandes Christina , Blundell Barbara , Moran Rebecca J. , Gilbert Jessica M. , Liddiard Mark 
Published: April 2021

AbstractGrandparents become custodial carers of their grandchildren for a variety of reasons, including love, fear of losing the children to the system, efforts to protect children while managing relationships with the adult child (parent), policy impetus, and even for the convenience of child protection systems. As obvious candidates for care provision, grandparents report feeling pressured to take on care, and yet many grandcarers are poorly supported and feel taken for granted. Drawing on a mixed method study of grandparent carers and service providers located in Western Australia, we argue that there are important issues of inequity and injustice associated with being a grandcarer, in particular due to systemic and discursive failures to recognize the complexity and challenges of care provision. Misrecognition and epistemic injustice result in further marginalization and disempowerment, compounding barriers to accessing services and supports, which in turn impact upon child and family wellbeing. The aim of this article is to analyse the complex circumstances described by grandcarers and service providers in interview and survey data, highlighting issues of inequity and injustice and therefore areas for improving policy and services to support grandfamilies.
Shark conservation and blanket bans in the eastern Pacific Ocean
Authors: Castellanos‐Galindo Gustavo A. , Herrón Pilar , Navia Andrés F. , Booth Hollie 
Published: April 2021

AbstractSharks are one of the most threatened marine animals, with fishing identified as the prime human activity responsible for population declines. The tropical eastern Pacific, a biogeographic region spanning the coastal areas from Mexico to Peru including the Colombian Pacific coast and the Galapagos archipelago, forms critical habitat and migratory routes for sharks and other marine megafauna. The Colombian government recently announced a total (blanket) ban on all forms of shark fishing in the country, including artisanal and industrial. Prohibiting shark fisheries in Colombia could drive fishing and trade under‐ground, fueling criminality, and marginalization. This will not only undermine recent efforts of local communities and researchers to manage small‐scale fisheries, but will criminalize a key source of income for a historically marginalized part of Colombian society. To be effective and ethical, this government decision needs to be rethought incorporating a more holistic management strategy consented among different stakeholder groups.
Structural analysis of behavioral freedom in free‐ranging and captive chimpanzees
Authors: Morimura Naruki 
Published: April 2021

AbstractBehavioral freedom is becoming an increasingly important issue bridging animal welfare and conservation biology. This study focused on range size and spatiotemporal variation in Western chimpanzees, creating a novel index for behavioral freedom. Direct observations were conducted on a group of seven free‐ranging chimpanzees in Bossou, Guinea, during 10‐hr observation periods over 10 days, and on a group of five captive individuals at the Kumamoto Sanctuary during 7‐hr observation periods over 7 days. Bossou chimpanzees showed dynamic ranging patterns; their range size was larger, and their day and time‐of‐day ranges did not generally overlap. Additionally, the average time‐of‐day range was 5.2 times greater than the day range. In contrast, sanctuary chimpanzees showed a static ranging pattern, with a smaller range size and a time‐of‐day range to day range ratio of 1.0. Therefore, the time‐of‐day range to day range ratio is a suitable quantitative index of behavioral freedom in chimpanzees.

Published: April 2021

AbstractBackgroundThe efficacy of anti‐interleukin‐1 (IL‐1) drugs in kidney transplant patients with FMF‐AA who developed colchicine resistance has not been clearly demonstrated.MethodThirty nine kidney transplant recipients with FMF‐AA were evaluated. Group 1 consisted of patients who were in remission after transplantation with colchine and Group 2 included those who developed colchicine resistance.ResultsThe mean follow‐up of the patients was 88.5 ± 61.9 months. Following the treatment with IL‐1 antagonists; serum Amyloid A (SAA) averages (79.4 ± 35.3 mg/L) as well as the average number of hospitalizations per month due to FMF episodes (1.4 ± 0.5 times/month) decreased significantly (26.6 ± 25.9 mg/L and 0.1 ± 0.3 times/month) (p < .001). Rates of death with a functional graft were 30% and 0% in group 1 and 2 (p = .086). Biopsy‐proven AA amyloidosis recurrence in the allograft was observed in 11 of 19 (58%) and seven of nine (78%) patients in group 1 and 2, respectively. Interestingly, glomerular amyloid deposition was not present in the vast majority of biopsies. De novo vasculer amyloid deposition was observed during treatment.ConclusionIL‐1 antagonist drug and colchicine combination almost completely prevented acute FMF attacks in kidney transplant patients with colchicine resistance. However, amyloid accumulation did not cease during IL‐1 antagonist drug treatment.

AbstractTo determine the impact of initial vancomycin trough concentration (VTC) on mortality in adult patients in the intensive care unit (ICU) undergoing vancomycin therapy. During their first ICU stay, patients with initial VTC records after vancomycin treatment were recruited from the eICU Collaborative Research Database to this multicenter retrospective cohort study, and classified into four groups according to VTC: less than 10, 10–15, 15–20, and greater than 20 mg/L. Multivariable logistic regression and sensitivity analyses were performed to explore the association of VTC, as a continuous and categorical variable, with mortality. This study enrolled 7220 patients from 335 different ICUs at 208 hospitals. Multivariable logistic regression models indicated that VTC was positively correlated with ICU (odds ratio [OR], 1.028, 95% confidence interval [CI], 1.019–1.037) and hospital (OR 1.028, 95% CI, 1.020–1.036) mortalities. Moreover, compared with VTC less than 10 mg/L, VTCs of 10–15, 15–20, and greater than 20 mg/L were associated with a higher risk of ICU mortality (OR, 1.330, 95% CI, 1.070–1.653; OR, 1.596, 95% CI, 1.265–2.015; abd OR, 1.875, 95% CI, 1.491–2.357, respectively), and VTCs of 15–20 and greater than 20 mg/L were also correlated with increased hospital mortality (OR, 1.482, 95% CI, 1.225–1.793; and OR, 1.831, 95% CI, 1.517–2.210, respectively). Similar results persisted in patients with different Acute Physiology and Chronic Health Evaluation Ⅳ scores, creatinine clearance levels, ages, and body mass indexes. Our findings indicated a potential relationship of initial VTC with ICU and hospital mortalities in patients in the ICU. However, due to the retrospective nature of this study, future prospective studies or randomized controlled trials are needed to validate those results.

AbstractAimsTo examine heart failure (HF) and chronic kidney disease (CKD) risks reduction associated with sodium‐glucose cotransporter‐2 inhibitors (SGLT‐2i) compared to other glucose‐lowering drugs (oGLD) in the early stage of type 2 diabetes patients without established cardiovascular or renal diseases (CVRD‐free T2D).Materials and MethodsWe performed an observational cohort study using a Japanese hospital claims registry, Medical Data Vision. CVRD‐free T2D patients were identified between 1 April 2014 and 30 September 2018. SGLT‐2i and oGLD new users (and dipeptidyl peptidase 4 inhibitors [DPP‐4i] separately) were subjected to 1:1 propensity‐score matching analysis. Hazard ratios (HRs) of cardiorenal disease (HF and/or CKD), HF, CKD, stroke, myocardial infarction (MI), and all‐cause mortality, were estimated using unadjusted Cox regression.ResultsA total of 108 362 CVRD‐free patients including 54 181 SGLT‐2i and 54 181 oGLD users were matched. Baseline characteristics were well balanced (mean age 59.1 years, 63% male, and follow‐up 1.50 years [162 970 patient‐years]). Compared to oGLD group, SGLT‐2i group had lower risk of cardiorenal disease, HF, CKD, stroke, and all‐cause mortality with HRs (95% confidence intervals) 0.55 (0.49‐0.61), 0.73 (0.61‐0.87), 0.45 (0.39‐0.52), 0.69 (0.59‐0.81), and 0.52 (0.46‐0.58), respectively, while no difference in MI. These were consistent in 1:1 propensity‐score matching analysis between SGLT‐2i and DPP‐4i users (n = 17 232 in each group).ConclusionsIn Japanese CVRD‐free T2D patients, SGLT‐2i initiation was associated with lower risk of cardiorenal diseases, stroke, and all‐cause mortality compared to oGLD, suggesting preventive effect of SGLT‐2i treatment in the early stage of T2D patients without CVRD manifestation.

Published: April 2021

AbstractWith the widespread use of electronic medical records and administrative claims databases, analytic results from so‐called real‐world data have become increasingly important in healthcare decision‐making. Diabetes mellitus is a heterogeneous condition that involves a broad spectrum of patients. Real‐world database studies have been recognised as a powerful tool to understand the impact of current practices on clinical courses and outcomes, such as long‐term glucose control, development of microvascular or macro‐vascular diseases, and mortality. Diabetes is also a major global health issue and poses a significant social and economic burden worldwide. Therefore, it is critical to understand the epidemiology, clinical course, treatment reality, and long‐term outcomes of diabetes to determine realistic solutions to a variety of disease‐related issues that we are facing. In the present review, we summarise the healthcare system and large‐scale databases currently available in Japan, introduce the results from recent database studies involving Japanese patients with diabetes, and discuss future opportunities and challenges for the use of databases in the management of diabetes.

Published: April 2021

AbstractBackgroundAt the patient level, the prognostic value of several features that are known to be associated with an increased risk of converting from relapsing−remitting (RR) to secondary phase (SP) multiple sclerosis (MS) remains limited.MethodsAmong 262 RRMS patients followed up for 10 years, we assessed the probability of developing the SP course based on clinical and conventional and non‐conventional magnetic resonance imaging (MRI) parameters at diagnosis and after 2 years. We used a machine learning method, the random survival forests, to identify, according to their minimal depth (MD), the most predictive factors associated with the risk of SP conversion, which were then combined to compute the secondary progressive risk score (SP‐RiSc).ResultsDuring the observation period, 69 (26%) patients converted to SPMS. The number of cortical lesions (MD = 2.47) and age (MD = 3.30) at diagnosis, the global cortical thinning (MD = 1.65), the cerebellar cortical volume loss (MD = 2.15) and the cortical lesion load increase (MD = 3.15) over the first 2 years exerted the greatest predictive effect. Three patients’ risk groups were identified; in the high‐risk group, 85% (46/55) of patients entered the SP phase in 7 median years. The SP‐RiSc optimal cut‐off estimated was 17.7 showing specificity and sensitivity of 87% and 92%, respectively, and overall accuracy of 88%.ConclusionsThe SP‐RiSc yielded a high performance in identifying MS patients with high probability to develop SPMS, which can help improve management strategies. These findings are the premise of further larger prospective studies to assess its use in clinical settings.
Fog‐assisted virtual reality‐based learning framework to control panic
Authors: Sood Sandeep Kumar , Rawat Keshav Singh 
Published: April 2021

AbstractThe biggest challenges for several universities and educational institutions throughout the COVID‐19 pandemic are online and e‐learning infrastructure availability. The incorporation of Information and Communication Technologies in the domain of disaster management is one such dimension, which focuses on the sustainability of human beings regarding the handling of unexpected pandemics. Therefore, it is important to evaluate the panic well‐being of the student in this situation. Moreover, virtual reality technology provides a virtual classroom environment that improves the skill and knowledge of the students at remote sites. In this paper, a fog‐assisted cyber physical system is proposed that deals with the various aspects of the panic well‐being of the student, including the virtual reality platform for remote learning. The proposed system utilizes the concepts of physical and cyberspace. The physical space facilitates real‐time data acquisition, and cyberspace determines and predicts the panic well‐being of the student. The performance assessment of the proposed model acknowledges the efficiency of the virtual learning system and panic well‐being determination and prediction. The proposed system also discussed a virtual learning system that provides a virtual classroom environment to the students at remote sites and reduces the panic due to stressful times during the COVID‐19 pandemic.
