Epidemics and Chinese firms' stock returns: is COVID-19 different?
Authors: Nguyen Quang Thi Thieu , Anh Dao Le Trang , Gan Christopher 
Published: July 2021

PurposeThis study investigates the Chinese stocks' returns during different epidemic periods to assess their effects on firms' market performance.Design/methodology/approachThe study employs an event study method on more than 3,000 firms listed on Shanghai and Shenzhen stock exchanges during periods of SARS, H5N1, H7N9 and COVID-19FindingsEpidemics' effect on firms' stock returns is persistent up to 10 days after the event dates. Although the impact varies with types and development of the disease, most firms experience a negative impact of the epidemics. Among the epidemics, COVID-19 has the greatest impact, especially when it grows into a pandemic. The epidemics' impact is uneven across industries. In addition, B-shares and stocks listed on Shanghai Stock Exchange are more negatively influenced by the epidemic than A-shares and those listed on Shenzhen Stock Exchange.Research limitations/implicationsThe results of the study contribute to the limited literature on the effects of disease outbreaks as an economic shock on firm market performance. Given the possibility of other epidemics in the future, the study provides guidance for investors in designing an appropriate investing strategy to cope with the epidemic shocks to the market.Originality/valueThe research is novel in the way it compares and assesses the economic impact of different epidemics on firms and considers their impact at different development stages.
The Covid-19 pandemic and technical efficiency of Russian firms: a stochastic frontier production function approach
Authors: Singh Parul , Arora Kashika , Siddiqui Areej Aftab 
Published: July 2021

Purpose
This paper aims to undertake the efficiency analysis in the form of stochastic frontier to estimate a Cobb–Douglas production function by controlling for the heterogeneity across Russian firms by including firm size, ownership, age, innovation activity and market competition.

Design/methodology/approach
During the peak period of Covid-19, certain firms witnessed either a decrease or increase in sales. Using this segregation of firms from World Bank’s Covid-19 impact surveys follow-up to the Enterprise Survey for Russia, this study empirically investigates the determinants of technical efficiency of these firms focusing on the role of government assistance.

Findings
The findings suggest that by segregating firms in terms of sales, different internal factors can enable in steering through pandemic situation besides just depending on external assistance.

Originality/value
One of the few papers to analyse the impact of the pandemic on Russian firms by considering World Bank Covid Survey.
Key factors of entrepreneurial university transformation: a model development using ISM method and MICMAC analysis
Authors: Novela Selly , Syarief Rizal , Fahmi Idqan , Arkeman Yandra 
Published: July 2021

PurposeThis study aims to develop a new entrepreneurial university model that will provide a comprehensive picture and explain how universities can become entrepreneurial by considering several factors, both internal and external.Design/methodology/approachThis research collected data by conducting a survey and elaborates on the judgments of informants who are experts in their fields. The gathered data were analyzed with the ISM method and MICMAC analysis.FindingsThis study identifies key factors of entrepreneurial university transformation, specifically, five key success factors and one constraint factor.Research limitations/implicationsThis study has limitations in terms of its in conducting interview techniques. Data collection, which should be maximized in producing agreement through focus group discussions, can more acutely identify factors through consensus.Practical implicationsThis study provides an overview of how universities may transform, following a path to become entrepreneurial by paying attention to the factors driving this transformation. The model demonstrates that while the university plays a central role, the participation of other parties within the ecosystem is also important.Originality/valueThis modeling technique deconstructs a complex system into several sub-systems, so that it can be studied in greater depth. Using ISM and MICMAC, a hard system methodology, this study advances a different and more comprehensive model.
Leader moral disengagement and follower knowledge hiding. A moderated mediation model of follower Machiavellianism and trust in the leader
Authors: Erkutlu Hakan , Chafra Jamel 
Published: July 2021

PurposeThis study aims to build a moderated mediation model to investigate the roles that trust in the leader and follower Machiavellianism can play in the relationship between moral disengagement of the leader and hiding of knowledge of the followers.Design/methodology/approachData were gathered from eight universities in Turkey using a set of 72 matched leader (dean)–follower (faculty member) questionnaires. The hypotheses were tested with multiple regression, moderated regression and bootstrapping analyses.FindingsThe findings reveal that leader moral disengagement positively influences follower knowledge hiding, while trust in the leader mediates this influence and follower Machiavellianism not only moderates the relationship between leader moral disengagement and trust in the leader but also reduces the indirect relationship between leader moral disengagement and follower knowledge hiding through trust in the leader.Research limitations/implicationsEven though measurements of research variables were collected from different sources and with time separation, common method bias might have existed. Also, this research is carried out in a single cultural context posing the issue of the generalizability of our findings to other cultural contexts.Originality/valueThe main contribution of this study is to construct and investigate a conceptual model that focuses on the possible effect of moral disengagement of the leader on knowledge hiding by the followers. Also, by supporting the mediating role of trust in the leader, this research reveals that followers of leaders with high moral disengagement are more prone to indulge in the hiding of knowledge. Moreover, the moderating role of follower Machiavellianism, found in this study, provides an additional understanding that followers may vary in the degree to which they are sensitive to the leader's influence.
Role of religiosity and the mediating effect of luxury value perception in luxury purchase intention: a cross-cultural examination
Authors: Rehman Anis Ur , Al Shammari Serhan , Al-Mamary Yaser Hasan 
Published: July 2021

Purpose
This study aims to explore the relationship between consumers’ religiosity, their perceived functional, individual and social value of luxury and their luxury purchase intention.

Design/methodology/approach
The proposed relationships were explored in an intercultural setting by using samples from two considerably different cultures, Saudi Arabia and India. The identified constructs were measured by adapting the established scales. Statistical tests including exploratory factor analysis, multi-group confirmatory factor analysis and covariance-based structural equation modeling were applied to test the conceptual model and research hypotheses.

Findings
The results show that religiosity is not found to be negatively related to luxury purchase intention in both samples. Moreover, it was found that the functional and social values produce positive mediating effects, whereas the individual values (materialism, hedonism) of luxury products negatively mediate the relationship between religiosity and consumer purchase intention.

Practical implications
This research suggests that a non-traditional strategy may be effective to market luxury goods to religious consumers such as suppressing the materialistic aspect to focus on the quality and functionality aspects of the products.

Originality/value
The role of luxury value perception as a mediator between religiosity and luxury purchase intentions has not been studied in the previous researches to the best of authors’ knowledge, and is therefore, the unique contribution of this study. This research addresses the gap in the existing body of knowledge by probing how religiosity effects perceptions of luxury value and resultant luxury purchase intention.
National risk assessment – the Croatian features
Authors: Cindori Sonja 
Published: July 2021

Purpose
The purpose of this paper is to present the risk of the non-financial sector in Croatia concerning the threats of money laundering through the prism of national and supranational risk assessment. In addition to a brief overview of the financial sector, the specifics of the non-financial sector have been highlighted. This paper aims to emphasize the peculiarities of the non-financial sector, focusing on the consequences of arbitrary application on the right to professional secrecy and independence.

Design/methodology/approach
Specifics of the national risk assessment in Croatia have been analyzed using deductive and inductive methods. To provide an overview of the non-financial sector, the risk assessment at the supranational level has been discussed and compared with the national one. Particular attention has been paid to the areas of increased risk.

Findings
The effectiveness of risk assessment depends on several factors such as the characteristic of the sector being observed, the specifics of each profession or business, changes at the level of awareness-raising and efficient and coherent supervision. Most deficiencies were observed in the area of beneficial ownership identification, conducting due diligence, awareness of the risk exposure and permanent education.

Originality/value
By recognizing the risk profile faced by the non-financial sector, this paper seeks to point out their role as “Gatekeepers” that is far from being negligible. By analyzing the risk of money laundering in Croatia, the tendencies of harmonization with international standards are pointed out along with the occurrences indicated by the practice.
Entrepreneurial orientation, externalities and social entrepreneurship
Authors: Gauthier Jeffrey , Cohen David , Meyer Christopher R. 
Published: July 2021

PurposeThe purpose of this paper is to consider how the dimensions of entrepreneurial orientation (EO) may support or diminish the creation of social value.Design/methodology/approachThe approach applies Lumpkin and Dess’s multidimensional conceptualization of EO to the growing body of literature on social entrepreneurship.FindingsPropositions on the effects of autonomy, competitive aggressiveness, innovativeness, proactiveness and risk-taking on social value creation are developed.Research limitations/implicationsThe propositions offered in the paper suggest avenues for future empirical studies that seek to examine the impact of EO on social, rather than financial, performance.Originality/valueA significant body of research has examined the relationship between EO and financial performance, but potential implications for social value creation remain unclear. This paper seeks to address this gap in understanding of EO and social entrepreneurship and argues that two components of EO may adversely impact the creation of social value.
From critical pedagogy to critical digital pedagogy: a prospective model for the EFL classrooms
Authors: Masood Marwa Mohammad , Haque Md. Mahmudul 
Published: July 2021

PurposeCritical digital pedagogy (CDP) is an emerging field in education. The basic tenet of CDP involves taking learners' experiences into account and engaging them in critical thinking about social oppression. With the outbreak of the unprecedented COVID-19 pandemic, CDP has got more currency and appropriacy in the current paradigm shift in learning and teaching.Design/methodology/approachThis paper scrutinizes different aspects of CDP including its origins, theoretical underpinnings and its implementation in different contexts. It also critically reviews Freire's (1972) problem-posing education and Morris and Stommel's (2017) model of CDP.FindingsThe article proposes a CDP model based on the previous ones, which includes the core concepts and criteria of CDP and focuses on EFL classrooms.Research limitations/implicationsOne of the limitations of CDP is gaining the learners' approval in creating an environment of co-constructing knowledge moving away from traditional practices. In addition to that, the use of new media in the classroom can be intimidating for students and stakeholders alike. The lack of logistic support in many rural, remote and underdeveloped contexts cannot be ignored eitherPractical implicationsThe paper provides recommendations for future research in CDP.Originality/valueCritical pedagogy (CP) is a teaching approach in which the oppressed are basically focused and teachers and learners construct knowledge together. Recently, with the outbreak of the COVID-19 pandemic, global education had to go online. Consequently, traditional teaching and learning had to undergo a paradigm shift. Along with other changes in traditional teaching and learning practices, there has been a significant change in teaching philosophy. This is how the CDP finds its currency in this emerging unprecedented teaching and learning situation.
The transition to adulthood for autistic young people with additional learning needs: the views and experiences of education professionals in special schools
Authors: Crane Laura , Davies Jade , Fritz Anne , O’Brien Sarah , Worsley Alison , Ashworth Maria , Remington Anna 
Published: July 2021

Education professionals (n = 41) in special schools were interviewed about supporting their autistic pupils transitioning to adulthood following the introduction of the Children and Families Act 2014. Our participants explained how they lacked the time to fully implement knowledge gained from training, leading to growing reliance on experiential expertise. While our participants reported employing a variety of methods to elicit the voices of pupils, they were uncertain how effective and ethical these were. Further, a lack of available opportunities meant that participants felt they could not always support young people in achieving their goals. Based on these findings, we recommend greater investment in the implementation of staff training, more flexibility for schools to be able to meaningfully elicit and act on pupils' voices, and better vocational opportunities for autistic young people with additional learning needs. This would enable the principles of the Act, which have been widely lauded, to become a closer reality.
Sabre‐sheath trachea: An underused diagnostic weapon in the thoracic armoury
Authors: Brassil Colm , Srigandan Shrivuthsun , Murray Conor P 
Published: July 2021

AbstractIntroductionA sabre‐sheath trachea is a highly specific sign for chronic obstructive pulmonary disease. It also correlates well with the degree of disease. We hypothesized that the term is vastly under‐utilized in radiologic reporting, despite its high diagnostic value.MethodsWe interrogated our multisite metropolitan‐wide radiology information system to find the number of CT reports containing the phrase ‘sabre‐sheath trachea’ and conceivable variants thereof, over the 10 years to present. We compared this with the entire number of CT chest reports in the same time period in order to estimate the utilization of the sign.ResultsThe results confirmed our hypothesis that the sign is rarely invoked, likely around 1 in 41 times relative to opportunity.ConclusionsThis highly specific sign of chronic obstructive small airway disease should be reinforced in training and utilized by radiologists.
The need for improved patient reported outcome measures in patients with extremity sarcoma: a narrative review
Authors: Blight Thomas J. , Choong Peter F.M. 
Published: July 2021

AbstractBackgroundExtremity sarcoma causes impairments to functionality and quality of life. Patient‐reported outcome measures (PROMS) assess patient perspectives relating to domains of health and quality of life.MethodsTo describe PROMs utilised in extremity sarcoma, the available literature was screened for studies that utilised PROMs to evaluate outcomes in extremity sarcoma following surgery.ResultsSeventy articles met eligibility criteria; six PROMs were identified. The Toronto Extremity Salvage Score, The Short‐Form 36, The EORTC QLQ‐C30, The Disabilities of the Arm, Shoulder and Hand questionnaire, the Reintegration to Normal Living index and the Patient‐Reported Outcomes Measurement Information System. Most sarcoma patients score well in these tools, with bone sarcoma, and extent of resection being predictors of poor outcomes.ConclusionTESS is the only sarcoma‐specific PROM, and though a valid assessment of functionality, it has difficulty differentiating patients with minor functional impairments. The absence of a disease‐specific measure of health is concerning, as generic tools do not account for the unique experiences sarcoma patients face and may impair their accuracy in analysing intervention effectiveness.

SummaryBackgroundTegoprazan is a novel, fast‐ and long‐acting potassium‐competitive acid blocker that suppresses gastric acid secretion, which could benefit patients with non‐erosive reflux disease (NERD), a type of gastroesophageal reflux disease.AimTo evaluate the efficacy and safety profiles of tegoprazan compared with those of a placebo in Korean patients with NERD.MethodsIn this phase 3, double‐blind, placebo‐controlled, multicentre study, 324 Korean patients with NERD were randomised into three treatment groups: tegoprazan 50 mg, tegoprazan 100 mg and placebo. These drugs were provided once daily for 4 weeks. The primary endpoint was the proportion of patients with complete resolution of major symptoms (both heartburn and regurgitation) for the last 7 days of the 4‐week treatment period. Other outcomes related to efficacy, safety and tolerability were also evaluated.ResultsAmong all, 42.5% (45/106), 48.5% (48/99) and 24.2% (24/99) of patients showed complete resolution of major symptoms at week 4 after receiving tegoprazan 50 mg, tegoprazan 100 mg, and placebo, respectively. Both doses of tegoprazan showed superior efficacy than the placebo (P = 0.0058 and P = 0.0004, respectively). The complete resolution rates of heartburn and proportions of heartburn‐free days (as other efficacy outcomes) were significantly higher in both tegoprazan groups than in the placebo group (P < 0.05 for all). No significant difference in the incidence of treatment‐emergent adverse events were noted.ConclusionsTegoprazan 50 and 100 mg showed superior therapeutic efficacy compared with the placebo, as well as a favourable safety profile in patients with NERD.Registration number: ClinicalTrials.gov identifier NCT02556021.

AbstractObjectivesWe retrospectively investigated if robot‐assisted laparoscopic partial nephrectomy (RAPN) contributes to a decrease in resected parenchymal volume (RPV), an increase in postoperative parenchymal volume (PPV), and an improvement of postoperative renal function when compared with conventional laparoscopic partial nephrectomy (LPN) using a three‐dimensional image analysis system.MethodsPatients who underwent LPN (n = 37) and RAPN (n = 66) from November 2013 to November 2018 were included in this study. All patients had a tumor diameter of 4 cm or less. Patients with an anatomical or functional single kidney were excluded. RPV and PPV were measured using SYNAPSE VINCENT®. The surgical outcomes were compared between the two groups.ResultsWarm ischemic time in the RAPN group was significantly shorter than that in the LPN group (p < 0.001). The ratio of RPV to tumor volume (RPV/TV) in the RAPN group was significantly lower than that in the LPN group (p = 0.016). PPV in the RAPN group was significantly higher than that in the LPN group (p = 0.049). The decreased estimated glomerular filtration rate in the RAPN group was significantly lower than that in the LPN group on days 1, 7, 30, 90, and 180 after surgery.ConclusionsPostoperative renal function in the RAPN group was significantly better than that in the LPN group in both the short and long term. In addition to a short warm ischemia time, the decreased RPV/TV and increased PPV may have contributed to the improvement of postoperative renal function.
