Authors: Trichilli Yousra , Gaadane Sahbi , Boujelbène Abbes Mouna , Masmoudi Afif 
Published: July 2022

PurposeIn this paper, the authors investigate the impact of the confirmation bias on returns, expectations and hedging of optimistic and pessimistic traders in the cryptocurrencies, commodities and stock markets before and during COVID-19 periods.Design/methodology/approachThe authors investigate the impact of the confirmation bias on the estimated returns and the expectations of optimistic and pessimistic traders by employing the financial stochastic model with confirmation bias. Indeed, the authors compute the optimal portfolio weights, the optimal hedge ratios and the hedging effectiveness.FindingsThe authors find that without confirmation bias, during the two sub periods, the expectations of optimistic and pessimistic trader’s seem to convergence toward zero. However, when confirmation bias is particularly strong, the average distance between these two expectations are farer. The authors further show that, with and without confirmation bias, the optimal weights (the optimal hedge ratios) are found to be lower (higher) for all pairs of financial market during the COVID-19 period as compared to the pre-COVID-19 period. The authors also document that the stronger the confirmation bias is, the lower the optimal weight and the higher the optimal hedge ratio. Moreover, results reveal that the values of the optimal hedge ratio for optimistic and pessimistic traders affected or not by the confirmation bias are higher during the COVID-19 period compared to the estimates for the pre-COVID period and inversely for the optimal hedge ratios and the hedging effectiveness index. Indeed, either for optimists or pessimists, the presence of confirmation bias leads to higher optimal hedge ratio, higher optimal weights and higher hedging effectiveness index.Practical implicationsThe findings of the study provided additional evidence for investors, portfolio managers and financial analysts to exploit confirmation bias to make an optimal portfolio allocation especially during COVID-19 and non-COVID-19 periods. Moreover, the findings of this study might be useful for investors as they help them to make successful investment decision in potential hedging strategies.Originality/valueFirst, this is the first scientific work that conducts a stochastic analysis about the impact of emotional biases on the estimated returns and the expectations of optimists and pessimists in cryptocurrency and commodity markets. Second, the originality of this study stems from the fact that the authors make a comparative analysis of hedging behavior across different markets and different periods with and without the impact of confirmation bias. Third, this paper pays attention to the impact of confirmation bias on the expectations and hedging behavior in cryptocurrencies and commodities markets in extremely stressful periods such as the recent COVID-19 pandemic.

Published: July 2022

PurposeThe aim of this study was to conduct a comprehensive investigation into declining and emerging occupations and job titles and to develop a national career progression pathway for the tourism and hospitality (T&H) sector.Design/methodology/approachAnchored on the Social Cognitive Career Theory, this study used face to face in-depth interviews of 33 industry stakeholders: policymakers, trade association, training providers and beneficiaries (T&H).FindingsThe finding reveals that only the “watchman” occupation was identified as the declining job while majority of the emerging jobs were more related to information technology and environmental occupations (website designers, digital marketers, data analysts, hygienists, and safety and hazard experts).Practical implicationsThe findings provide a valuable signal for the growing number of jobs in security services, hygiene and information technology-oriented occupations, which the Ministry of Tourism, Arts and Culture including practitioners including HR directors and general managers should respond timely to and to these growing needs in order to remain competitive in the sector.Originality/valueThis is the first study in context that responded to a call by industry players to fill in a practical knowledge gap in examining declining and emerging jobs and job titles in the T&H sector. The study provides vocational insights into mapping the entry level requirements for the jobs allied with occupations in the national technical and vocational educational training qualifications framework of Ghana at the national level.
The strategic role of firm agility in the relationship between IT capability and firm performance under the COVID-19 outbreak
Authors: Bai Bingfeng , Um Ki-Hyun , Lee Hanna 
Published: July 2022

Purpose
Leveraging theory from the dynamic capability literature, this study aims to explore how information technology (IT) capability influences firm agility and subsequently translates into firm performance.

Design/methodology/approach
This study examines the proposed relationships by using survey data from a sample of 296 Chinese retail firms. Structural equation modeling is used to test this study’s hypotheses.

Findings
The following results are produced: the direct effect of IT capability on firm agility is confirmed; firm agility has a direct impact on firm performance; and the indirect effect of IT capability on firm performance via firm agility is demonstrated (i.e. partial mediation).

Originality/value
The catastrophic outbreak of the COVID-19 pandemic has heightened the importance of firm agility more than ever. Although the traumatic event is painful, however, there is nothing like a crisis to offer a tremendous business opportunity. In response to the pandemic circumstance, firms are required to operate their business by reacting to unpredictable and dynamic market changes quickly and efficiently. This study sheds light on why firms should develop their IT capability and how it affects firm performance via firm agility during the COVID-19 outbreak.
Compliance risks for crowdfunding. A neglected aspect of money laundering, terrorist financing and fraud
Authors: Teichmann Fabian , Boticiu Sonia Ruxandra , Sergi Bruno S. 
Published: July 2022

Purpose
This study aims to highlight the risks and threats posed by crowdfunding. It also looks at the new European Union regulation on crowdfunding, which is intended to give participants confidence that there will be specific minimum regulatory standards to protect parties against mis-selling issues affecting some platforms.

Design/methodology/approach
This paper is based upon a thorough literature review.

Findings
Crowdfunding is an essential alternative for financing commercial and non-commercial projects. Although it is a fast-growing digital financial tool, it can also be considered extremely risky. It can be an ideal platform for money laundering and can facilitate the financing of terrorism and fraud.

Originality/value
Crowdfunding is still in its infancy, so the literature has not yet sufficiently addressed the compliance risks of crowdfunding. As a result, there is a significant research gap. Thus, this study aims to analyse and propose suggestions to mitigate the risks that all crowdfunding stakeholders may face when deciding to participate in a crowdfunding activity or when they want to set one up.

Authors: Mawardi Imron , Widiastuti Tika , Al Mustofa Muhammad Ubaidillah , Hakimi Fifi 
Published: July 2022

Purpose
This study aims to investigate the effects of zakat and business assistance on the growth and well-being of mustahiqs (zakat recipients). This study also investigates the impact of macroeconomic variables on the welfare of mutahiqs.

Design/methodology/approach
The partial least squares-structural equation modelling method is used in this quantitative study, examining data from 137 mustahiqs. The data was collected from seven zakat institutions, which run effective zakat programmes to empower mustahiqs.

Findings
Zakat empowerment programmes and business assistantships positively impact the growth of mustahiqs’ businesses, beneficial to their well-being. Nevertheless, their well-being is unaffected by the proxy of the macroeconomy.

Originality/value
This study adds to the zakat literature by identifying the relationship between zakat, business growth, macroeconomic conditions and mustahiq welfare. Accordingly, this approach was made by combining primary and secondary data. This research offers a unique measure of welfare based on the concept of the Islamic objectives (Maqasid al-Shariah).

Authors: McKeon Grace , Fitzgerald Caroline , Furzer Bonnie , Rosenbaum Simon , Stanton Robert , Lederman Oscar , Harvey Samuel B. , Wright Kemi 
Published: July 2022

Purpose
Physical activity is an important component of treatment for people living with mental illness, and exercise practitioners are well placed to deliver these interventions. In response to the COVID-19 pandemic and associated lock-down regulations, exercise professionals have rapidly adapted to the online delivery of services to continue care for their clients. To date, the research surrounding the delivery of exercise sessions via telehealth for this population has been scarce. Therefore, this study aims to explore how exercise professionals working in mental health have adapted to telehealth, the barriers and facilitators they have experienced and the implications for the future.

Design/methodology/approach
A qualitative study using semi-structure interviews was conducted. Interviews were audio recorded, transcribed and analysed using reflexive thematic analysis.

Findings
Nine exercise physiologists working in mental health settings in Australia participated in the interviews. Two main themes were explored. The first related to the implementation of telehealth and was divided into four sub-themes: service delivery, accessibility and suitability, technology barriers and facilitators, adaptations to exercise prescription. The second theme related to attitudes and was categorised into two sub-themes: attitudes towards telehealth and future recommendations.

Practical implications
Telehealth appears to be a feasible and well accepted platform to deliver exercise sessions for people with mental illness, and this study provides guidance for clinicians including service and training recommendations.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine the experiences of exercise physiologists working in mental health and using telehealth.
An empirical study to prioritize the determinants of corporate sustainability performance using analytic hierarchy process
Authors: Mal Hoshiar , Varma Manishkumar , Vishvakarma Niraj Kumar 
Published: July 2022

Purpose
The use of natural resources by organizations has a significant impact on society, resulting in business firms playing a vital role in developing sustainable development. As a result, corporate sustainability has become an integral aspect of a company’s vision and policy in the modern days. Companies issue sustainability reports based on various criteria and metrics, thereby attempting to gain a competitive edge. This study aims to assess and prioritize the numerous factors that influence corporate sustainability performance.

Design/methodology/approach
The analytic hierarchy process (AHP) is used to prioritize the identified determinants of corporate sustainability performance based on the literature. Several experts from business and academia were engaged to build a comparison matrix for assessing the various aspects of corporate sustainability performance. As a result, various corporate sustainability determinants were determined and prioritized following an extensive literature review using the AHP.

Findings
The most critical component for companies is an economic indicator. Developing environmentally and socially responsible suggestions must be a priority for the organization’s economic performance. Economic performance is believed to be most heavily influenced by innovation and in the other category like environmental and social performance are highly influenced by environment management policies and shareholder responsibility, respectively. Researchers’ findings suggest that to promote sustainability, top executives should devote all of their attention to innovation, environment management policies and shareholder responsibility.

Research limitations/implications
These studies are primarily concerned with developed countries. And, the other fundamental constraint of the AHP study is that the rating scale adopted in the analysis is conceptual. Therefore, pairwise comparisons with a variety of indicators have the potential to introduce bias into the results.

Practical implications
This paper proposes a methodical and operational technique for selecting the ultimate priority of sustainability indicators when it comes to exploiting competitive information on business performance. The paper also recommended sustainability rating technique might be carried out once every six months to improve the overall quality and performance of the organization.

Originality/value
The advantages of adopting and executing corporate sustainability are enormous, and managers must determine whether sustainability is profitable or not. This question prompts further inquiries. For example, what are the numerous critical determinants of corporate sustainability performance? Several scholars throughout the world are looking at it for this reason. As a result, it is essential to comprehend and prioritize the various determinants of corporate sustainability performance.
Influences of political connections on entrepreneurs' subjective well-being: a multilevel investigation
Authors: Xu Feng , Yang Xueru , He Xiaogang 
Published: July 2022

PurposePolitical connections are widely acknowledged as an effective political strategy for achieving firm value. However, surprisingly little is known about the association between political connections and individual-level outcomes (e.g. subjective well-being) and the underlying mechanism for this link.Design/methodology/approachDrawing on the schematic model of social capital and entrepreneurship and utilizing a sample of rural Chinese entrepreneurs, the authors developed and tested a multilevel model delineating the impact of political connections on entrepreneur well-being (job and life satisfaction) via the mediating roles of bribing behavior and institutional trust at individual and provincial levels.FindingsMultilevel analyses revealed that at the individual level, political connections were positively associated with job and life satisfaction; bribing behavior and institutional trust served as partial mediators of these associations. These effects were deviated when examining them at the provincial level.Research limitations/implicationsThe theoretical implications concerning the political connections and subjective well-being effects as well as comparative entrepreneurship were discussed.Practical implicationsFurther, the authors provide guidance for both entrepreneurs and policymakers.Originality/valueThe study linked political connections to entrepreneurs' subjective well-being which is increasingly seen as an important ingredient of personal success via distinguishing the individual-level effects from the provincial-level effects. Thus, the study further contributes to the contextualized understanding of the entrepreneurship literature.

AbstractWe investigated whether a set of phylogeographical tracked emergent events of Orthocoronavirinae were related to developed, urban and polluted environments worldwide. We explored coronavirus records in response to climate (rainfall parameters), population density, CO2 emission, Human Developmental Index (HDI) and deforestation. We contrasted environmental characteristics from regions with spillovers or encounters of wild Orthocoronavirinae against adjacent areas having best‐preserved conditions. We used all complete sequenced CoVs genomes deposited in NCBI and GISAID databases until January 2021. Except for Deltacoronavirus, concentrated in Hong Kong and in birds, the other three genera were scattered all over the planet, beyond the original distribution of the subfamily, and found in humans, mammals, fishes and birds, wild or domestic. Spillovers and presence in wild animals were only reported in developed/densely populated places. We found significantly more occurrences reported in places with higher HDI, CO2 emission, or population density, along with more rainfall and more accentuated seasonality. Orthocoronavirinae occurred in areas with significantly higher human populations, CO2 emissions and deforestation rates than in adjacent locations. Intermediately disturbed ecosystems seemed more vulnerable for Orthocoronavirinae emergence than forested regions in frontiers of deforestation. Sadly, people experiencing poverty in an intensely consumerist society are the most vulnerable.
Transcendent pluralism: A middle‐range theory of nonviolent social transformation through human and ecological dignity: Analysis and evaluation
Authors: Bryant April 
Published: July 2022

AbstractBackgroundIssues such as group bias, poverty, disempowerment, and violence contribute to poor health outcomes among at‐risk populations. In all countries, there exist disparities among health status with worse health outcomes in individuals categorized as having less access to resources. Systemic forces perpetuate health inequities among at‐risk populations furthering the divide between those in resource‐rich environments and those afflicted by a lack of resources. The social devaluing of individuals and their environment contributes to this ongoing global suffering.MethodIn this article, I critically appraised the theory of transcendent pluralism: a middle‐range theory of nonviolent social transformation through human and ecological dignity based on the criteria outlined by Fawcett.ConclusionThe concepts identified in this theory offer nursing the tools to facilitate social change. Despite the theory lacking significant real‐world nursing practice application, it has the potential to bridge nursing's ability to influence social change through research and practice.

Published: July 2022

AbstractThis study aimed to develop a predictive model to screen for undetected vertical root fractures (VRFs) in root canal treated teeth. We included 95 root canal treated teeth with suspected VRFs; 77 for training and 18 for validation. Following clinical and cone‐beam CT parameters were recorded: sex, tooth type, coronal restoration, time interval from completion of endodontic treatment to definitive diagnosis (TI), type of bone loss (BL), apical extent of root filling (AR) and the ratio of root filling diameter to the actual diameter in the coronal (1/3TA) and middle (2/3TA) root thirds. A predictive model p = 1/(1 – e−x) was generated, where x = −7.433 + 1.977BL + 1.479 (2/3TA) + 1.102 AR; the sensitivity and specificity were 0.852 and 0.875 for training and 0.917 and 0.833 for validation. VRF teeth were more likely to have vertical bone loss and overfilled root canals. This model had a high diagnostic efficacy for VRFs.

Published: July 2022

AbstractInformation on breeding habits of grey crowned crane (Balearica regulorum) in Kenya is currently lacking. Investigations were therefore carried out between 2017 and 2020 to determine its nesting habits in Lake Ol’ Bolossat basin including nest‐site features, number and distribution of territorial pairs, clutch size, eggs, and duration of breeding cycle. While 103 pairs were observed in the lake marshlands (mean density 5.00 pairs/km2), only 20 were found in upland wetlands. The number of pairs and densities (pairs/km2) in each of the lake's sections were as follows: north (24; 3.23), middle (47; 5.42), and south (32; 6.24). During this study, 61% (n = 63) of the lake marshland pairs attempted to breed compared to 80% (n = 16) in the upland wetlands. A mean of 2.23 eggs/clutch and a modal clutch of three eggs was recorded in 33 accessible nests. The range of influential factors in nest‐site selection were as follows: water depth (50–100 cm), vegetation height around the nest (60–90 cm), and an offshore distance of >100 m. Breeding cycle showed phenotypic plasticity in response to variations in local weather conditions. The number and density of cranes in this study area show its importance in the recovery and survival of the species, and which should subsequently be accorded effective protection.
Quantile Regression for Nonignorable Missing Data with Its Application of Analyzing Electronic Medical Records
Authors: Yu Aiai , Zhong Yujie , Feng Xingdong , Wei Ying 
Published: July 2022

Abstract
Over the past decade, there has been growing enthusiasm for using electronic medical records (EMRs) for biomedical research. Quantile regression estimates distributional associations, providing unique insights into the intricacies and heterogeneity of the EMR data. However, the widespread nonignorable missing observations in EMR often obscure the true associations and challenge its potential for robust biomedical discoveries. We propose a novel method to estimate the covariate effects in the presence of nonignorable missing responses under quantile regression. This method imposes no parametric specifications on response distributions, which subtly uses implicit distributions induced by the corresponding quantile regression models. We show that the proposed estimator is consistent and asymptotically normal. We also provide an efficient algorithm to obtain the proposed estimate and a randomly weighted bootstrap approach for statistical inferences. Numerical studies, including an empirical analysis of real-world EMR data, are used to assess the proposed method's finite-sample performance compared to existing literature.
