Authors: Tabassum Mimma , Parvej Md Iftakhar , Ahmed Firoz , Zafreen Farzana , Sultana Samina 
Published: February 2021

Purpose
COVID-19 pandemic has caused serious threat to peoples’ physical and mental health because of its high death toll all over the world within a very short period. As a result, people may be psychologically stressed, which can affect their quality of life. The main purpose of this study is to quantify the level of stress among the adults (age 18 and above) including all gender, religions and races of Bangladesh during this devastating pandemic.

Design/methodology/approach
This online survey-based study collected demographic data and the Perceived Stress Scale (PSS-10) to determine stress levels over past one month. The total numbers of respondents are 1,148 from May 29, 2020 to June 12, 2020; using the PSS to assess stress levels and to identify the potential variables having association with level of psychological stress, multinomial logistic regression analysis was performed.

Findings
A scary proportion (81%) of respondents suffered from substantial amount psychological stress during this COVID-19 pandemic. It is an undeniable signal for us that, every 4 out of 5 respondents in our study is suffering from different level of psychological stress during this time. Comparing the level of stress, this study finds that elderly (60 and above), women, front-line workers (doctor and other health-care professionals) and second-line workers (public service holders, police and defense and banks or financial institutes) have high psychological stress compared to the other respondents.

Originality/value
This study will help policymakers to provide relevant mental health intervention strategies to cope with this challenge efficiently.

An investigation of physical properties and photovoltaic performance of methylammonium lead-tin iodide (CH3NH3Sn1-xPbxI3) solar cells
Authors: Malekan Omid , Adelifard Mehdi , Mohagheghi Mohamad Mehdi Bagheri 
Published: February 2021

Purpose
In the past several years, CH3NH3PbI3 perovskite material has been extensively evaluated as an absorber layer of perovskite solar cells due to its excellent structural and optical properties, and greater than 22% conversion efficiency. However, improvement and future commercialization of solar cells based on CH3NH3PbI3 encountered restrictions due to toxicity and instability of the lead element. Recently, studies on properties of lead-free and mixture of lead with other cations perovskite thin films as light absorber materials have been reported. The purpose of this paper was the fabrication of CH3NH3Sn1-xPbxI3 thin films with different SnI2 concentrations in ambient condition, and study on the structural, morphological, optical, and photovoltaic performance of the studied solar cells. The X-ray diffraction studies revealed the formation of both CH3NH3PbI3 and CH3NH3SnI3 phases with increasing the Sn concentration, and improvement in crystallinity and morphology was also observed. All perovskite layers had a relatively high absorption coefficient >104 cm−1 in the visible wavelengths, and the bandgap values varied in the range from 1.46 to 1.63 eV. Perovskite solar cells based on these thin films have been fabricated, and device performance was investigated. Results showed that photo-conversion efficiency (PCE) for the pure CH3NH3PbI3sample was 1.20%. With adding SnI2, PCE was increased to 4.48%.

Design/methodology/approach
In this work, the author mixed tin and lead with different percentages in the perovskite thin film. Also, the preparation of these layers and also other layers to fabricate solar cells based on them were conducted in an open and non-glove box environment. Finally, the effect of [Sn/Pb] ratio in the CH3NH3Sn1-xPbxI3 layers on the structural, morphological, optical, electrical and photovoltaic performance have been investigated.

Findings
CH3NH3Sn1-xPbxI3 (x = 0.0, 0.25, 0.50, 0.75, 1.0) perovskite thin films have been grown by a spin-coating technique. It was found that as tin concentration increases, the X-ray diffraction and FESEM images studies revealed the formation of both CH3NH3PbI3 and CH3NH3SnI3 phases, and improvement in crystallinity, and morphology; all thin films had high absorption coefficient values close to 104 cm−1 in the visible region, and the direct optical bandgap in the layers decreases from 1.63 eV in pure CH3NH3SnI3 to 1.46 eV for CH3NH3Sn0.0.25Pb0.75I3 samples; all thin films had p-type conductivity, and mobility and carrier density increased; perovskite solar cells based on these thin films have been fabricated, and device performance was investigated. Results showed that photo-conversion efficiency (PCE) for the pure CH3NH3PbI3sample was 1.20%. With adding SnI2, PCE was increased to 4.48%.

Originality/value
The preparation method seems to be interesting as it is in an ambient environment without the protection of nitrogen or argon gas.
Sense of virtual community, commitment and knowledge contribution: an empirical research based on MI community
Authors: Yao Shanji , Zheng Xinnuo , Liu Dewen 
Published: February 2021

Purpose
The purpose of this paper is to find a way to encourage community members to actively create content and contribute knowledge through the study of the relationship between virtual community awareness, commitment and knowledge contribution, so as to make virtual community revitalize and provide a better platform for enterprises to carry out network marketing.

Design/methodology/approach
This study establishes a theoretical model that member knowledge contribution’s prepositive impact in virtual community. SOVC is an independent variable, commitment is a mediating variable and knowledge contribution is a dependent variable. Through 139 valid questionnaires from MI community, relationships among sense of virtual community (SOVC), commitment and knowledge contribution are deeply discussed.

Findings
Empirical results show that, as three dimensions of SOVC, membership, influence and immersion can all drive commitment and knowledge contribution in different degrees. In the two-dimensional division of commitment, only affective commitment can drive knowledge contribution. Affective commitment and calculative commitment can play a mediating role in the impact of SOVC on knowledge contribution.

Originality/value
Empirical research that the academia has done on important issues such as the impact of SOVC and commitment on knowledge contribution is deficient. Furthermore, those researches which have explored the mediating effect of commitment in the impact of SOVC on knowledge contribution remain merely on theoretical deduction level, and empirical studies based on Chinese background are also rare. In China, MI community is the typical representative of virtual community that runs successfully, and choosing it to conduct research can not only provide representatives on sample but also duplicate on the result popularity. Thus, this paper chooses MI community as the empirical object to explore the relationships among SOVC, commitment and knowledge contribution.

Authors: Wanyoike Caroline Njeri , Maseno Matilda 
Published: February 2021

PurposeThis paper aims to investigate the motivations of social entrepreneurs in East Africa to create a social enterprise and their identified links to successful social entrepreneurship in East Africa.Design/methodology/approachThe authors employed a qualitative method by performing thematic analysis on a set of interviews on social entrepreneurs from East Africa who are Ashoka fellows.FindingsThe findings suggest that intense personal experiences linked to past-life events as well as a high achievement orientation towards improving livelihoods and creating impact serve as key triggers for social entrepreneurship. Successful entrepreneurship focusses on system change at national and local levels. Their success is also seen when the social entrepreneurs have achieved their mission and are no longer needed; thus, they become irrelevant. The paper discusses the implications of these findings on the model used for sustainable social entrepreneurship in East Africa.Practical implicationsBased on an exploratory research on Ashoka fellows, the study adds insight to their motivations and success which can be used in a wider scale study of the same.Originality/valueThe authors advance the scarce empirical research on East African social entrepreneurs, link success factors of social entrepreneurship to a recent framework on motivation to engage in social entrepreneurship and stimulate further research in the area. The study contributes to the literature on social entrepreneurship by linking success factors of social entrepreneurship to a recent framework on motivation to engage in social entrepreneurship.
The effect of implicit (vs explicit) rejection on the behavioral intentions of online daters
Authors: Alba George 
Published: February 2021

PurposeOnline dating facilitates both dater interactions and rejections. Given the vast offer of potential mates and daters' limited time, several rejections may occur. On online dating platforms, most of these rejections are simply the absence of a reply (ignoring). The purpose of this paper is to compare the impact of implicit rejection (ignoring) vs explicit rejection (declining) on the behavioral intentions of daters, considering self-esteem as a moderator.Design/methodology/approachExperiment 1 investigated the effect of the extent of rejection (implicit vs explicit vs control) on the behavioral intentions of online daters. Experiment 2 assessed observers' recommended actions to a male (vs female) online dater following rejection (implicit vs explicit vs control).FindingsImplicit rejections generate greater behavioral intentions than explicit rejections. Both daters (study 1) and observers of the dating scenario (study 2) indicated greater intent to revise their profiles (study 1) or recommend a profile revision (study 2) when implicitly (vs explicitly) rejected by interaction partners. Self-esteem moderated the effect of the extent of rejection. Higher levels of self-esteem eliminate and lower levels of self-esteem intensify the effect of the extent of rejection on behavioral intentions. Additionally, observers' recommendations based on the extent of rejection depend on the rejected dater's gender.Originality/valueIgnoring is a frequent practice among dating platform users, and this paper provides an original contribution to better understand the differences stemming from implicit or explicit rejection of online daters.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-06-2020-0207
Board demographic diversity and human rights reporting in Western Europe
Authors: Branco Ana Paula Castelo , Bianchi Maria Teresa , Castelo Branco Manuel 
Published: February 2021

PurposeThis paper aims to examine the relationship between board demographic diversity and human rights reporting for a sample of large Western European companies.Design/methodology/approachGrounded on resource dependence theory, the authors hypothesize that greater gender, age and nationality diversities will translate into enhanced levels of human rights reporting. The authors use ordinal logistic regression analysis to analyze the association between these types of board diversity and such reporting.FindingsThe findings suggest that the companies in the sample attribute little importance to the reporting of information pertaining to the issue of human rights. They also suggest that only the diversity of nations represented in the board of directors is significant in explaining this type of reporting.Research limitations/implicationsThe sample includes only large companies from Western Europe and the analysis covers only one year.Originality/valueTo the best of the authors’ knowledge, this study provides the first empirical analysis of factors influencing human rights reporting conducted on a multiple-country setting. It is also the first investigating the association between boards of directors’ demographic diversity and such reporting.

Authors: Ephrem Ben George , Appaadurai Samuel Giftson , Dhanasekaran Balaji R. 
Published: February 2021

Purpose
The world has faced various epidemic situations caused by different viruses such as SARS-Cov, MERS-Cov, Ebola and many more during the past few decades, SARS-Cov-2 (COVID-19) is the genetic variant of newly the discovered Coronavirus, which has been believed to spread from China during December 2019, which has created a catastrophic effect for the whole world. In the first quarter of 2020, the virus started to spread to different countries, in addition, the severity of cases, the mortality rate and the recovery rate varied between countries. In the Sultanate of Oman and different parts of the world, the COVID started to spike during the end of March 2020. In this research paper, COVID data for Gulf Cooperation Council (GCC) countries are extracted and analysis has been made based on different parameters. The analysis has been divided into two categories – the first part focuses on the total number of cases, the total number of recoveries and the total number of deaths and comparison has been made for different GCC countries, from these analyses, it gives a clear picture of the days of a particular month, which contributes to the increase of COVID cases. The second part focuses on finding out the indicators that are correlating with the COIVD-19 cases and deaths; it has been found that there is a very strong correlation between the total population and labour force of every GCC country with the corresponding COVID cases and deaths.

Design/methodology/approach
The entire research steps involved starts with data collection, data pre-processing and data analysis. The analysis has been divided into two categories – the first part focuses on the total number of cases, the total number of recoveries and the total number of deaths and comparisons has been made for different GCC countries. The second part focuses on finding out the indicators that are correlating with COIVD-19 cases and deaths.

Findings
It has been found that there is a very strong correlation between the total population and labour force of every GCC country with the corresponding COVID cases and deaths.

Research limitations/implications
The data set considered is limited and can be extended further.

Social implications
This research paper definitely provides a road map for practice, as this research provides details about the total number of active cases, death based on the days in different GCC countries. It has been observed that during the end of each month and during weekends, the total number of cases increases drastically, so by taking into consideration the governing bodies can impose a lockdown during these spike durations. In addition to it, the citizens and residents should make a practice to avoid or limit their movement during the spike durations, which was analysed by this research work.

Financial battle against climate change – assessing effectiveness using a scorecard
Authors: Saliya Candauda Arachchige , Pandey Suesh Kumar 
Published: February 2021

Purpose
This paper aims to investigate how and to what extent the Fijian sustainable banking regulations or guidelines are designed, communicated, implemented and monitored within the financial system in Fiji. A scorecard is introduced for this purpose to assess the effectiveness of Fiji’s financial battle against climate change (FBACC).

Design/methodology/approach
This study uses a mixed-method methodology. Data were collected mainly from a survey and supplemented by interviews, observations and documents. The scorecard was developed by building on existing two theoretical frameworks, namely, the Sustainable Banking Assessment and Climate Change Governance Index, to make them more appropriate and practically applicable to less developed financial systems in emerging economies such as Fiji. This FBACC scorecard consists of four perspectives, eight critical factors and 24 criteria.

Findings
The results show that the overall FBACC score averages 40.75%, and all the perspectives scored below 50%, the benchmark. Only the CF “policy” scored 54.25% because of a high positive response of 82.3% for the “political leadership” criterion. The relative contributions of each perspective in constructing the overall score are distributed as 28%, 25%, 24% and 23% among planning, action, accountability and control, respectively.

Research limitations/implications
These results were complemented by the information shared during the interviews and confirmed that the existing political initiatives need to be effectively communicated and/or implemented in the financial system by the regulatory agencies.

Practical implications
This FBACC scorecard can be applied to other underdeveloped systems in emerging countries to assess the effectiveness of the sustainable banking regulations and/or guidelines in those countries in relation to the FBACC. It can also be applied to individual firms to assess their contribution to the FBACC.

Originality/value
To the authors’ best knowledge, this might be the first study in Fiji that considers the impact of climate-related financial risk on the Fijian financial system.
Resilience and stress management amongst corporate security managers: a hybrid approach to thematic analysis
Authors: Rahman Sami , Cachia Moira 
Published: February 2021

PurposeThe purpose of this study is to examine the experience of stress by national corporate security managers in the United Kingdom and how they manage it.Design/methodology/approachA qualitative approach was adopted where in-depth semi-structured one-to-one interviews with 22 male participants were conducted as the method of data collection. This was analysed using hybrid thematic analysis.FindingsThree overarching themes were elicited, namely: “Resilience”, “Synergy” and “Work/life balance”. The outcome showed that stress management by security managers is moulded by an interaction of various facets, with an emphasis on “resilience” having 66% of content occurrence, a factor which complements and enriches the job demand–control-support (JDCS) theoretical framework (Johnson and Hall, 1988).Practical implicationsThe paper argues the importance of the interaction between resilience and the dimensions of the JDCS. The research indicates the interaction is important in how practitioners can develop interventions in reducing stress in the workplace.Social implicationsThis research outcome implies that employees in managerial positions should be provided with resilience assessment and training to enhance their job effectiveness and well-being. Resilience needs to be recognised as an important trainable skill and stress management training should emphasise the enhancement of resilience.Originality/valueThis type of qualitative investigation on the lived experiences of stress management and how this affected one's resilience's in a high-stress industry is innovative as past research is mostly quantitative.
Influence of 3D printing process parameters on the mechanical properties and mass of PLA parts and predictive models
Authors: Afonso João Araújo , Alves Jorge Lino , Caldas Gabriela , Gouveia Barbara Perry , Santana Leonardo , Belinha Jorge 
Published: February 2021

Purpose
This paper aims to evaluate the influence of the parameters of the Fused Filament Fabrication (FFF) process on the mechanical properties and on the mass of parts printed in Polylactic Acid (PLA). In addition, the authors developed predictive models for the analysed responses.

Design/methodology/approach
A full Factorial type of experimental planning method was used to define the conditions for manufacturing parts according to the variation of the construction parameters, extrusion temperature and print speed. Samples were printed for tensile, flexion and compression tests. Their mass was measured. Multiple regression methods, based on power equations, were used to build the forecasting models.

Findings
It was found that the extrusion temperature was the parameter of greatest influence in the variation of the analysed responses, mainly because it generates behaviour patterns and indirectly demonstrates thermal/rheological characteristics of the material used. Print speed affects responses, however, with variations dependent on part geometry and printer hardware/software. It was possible to establish prediction models with low error rates in relation to the experimental values.

Originality/value
The study demonstrates a good relation between the use of a structured experimental planning method as the basis for the development of predictive models based on mathematical equations, the same structure of which can be used to describe different responses.
