Abstract
Purpose
An S-curve is an essential project-management tool. However, it is difficult to adjust S-curve to deal with a force majeure event. The present study develops four valuable adjustment approaches, designed to achieve a compromise between the views of the client and contractor. These can be used to control projects after a force majeure event.
Design/methodology/approach
The present study develops four adjustment approaches, which can be used to achieve a compromise between the views of the client and those of the contractor when controlling projects after a force majeure. To determine the S-curves during a force majeure event, two approaches can be selected: BCWS (budgeted cost of scheduled work)-base approach, or BCWP (budgeted cost of work performed)-base approach. To determine the rest of S-curves after a force majeure event, two approaches can be considered: maintaining the original curve of the remaining BCWS, or allocating the original curve of the remaining BCWS. Based on the validation of three empirical cases, drawn from a professional project-management website, this study confirms the feasibility of four proposed empirical approaches and a selection procedure for S-curve adjustment.
Findings
The S-curve-adjustment approaches presented here can be used to deal with cases that are ahead of, on and behind schedule. Using the proposed approaches and selection procedure, contractors can easily revise S-curves and control projects more effectively. To deal with a force majeure event, such as COVID-19, they are strongly advised to adopt the approaches labeled SA-A1 (to adjust the S-curve based on the extension ratio multiplied by the difference in progress during the force majeure) and SA-B1 (to maintain the original curve of the remaining BCWS) for the A/E and E/F curves, respectively.
Research limitations/implications
The proposed approaches can be used in cases of continuous construction during force majeure events. If construction work is totally suspended during such an event, it will be necessary to fine-tune the proposed approaches.
Originality/value
Previous studies have used case-oriented or mathematical-simulation approaches to forecast S-curves. The present study proposes simple approaches that allow the client and contractor to adjust the S-curve easily after a force majeure event. These approaches can be used to adjust work and project-completion targets within an extended duration. Selecting the right S-curve adjustment approach can help to control the remainder of the project, reducing the possibility of delay claims.

Abstract
Purpose
Micro, small and medium-sized enterprises (MSMEs) are vital for economic growth in developing countries. Yet, little research has explored the link between Islamic principles and MSME performance, especially in Uganda. This study aims to investigate the relationship between Islamic financial principles and MSMEs’ performance in Makindye Division Kampala – Uganda.
Design/methodology/approach
This study used a correlational research design involving 86 respondents from 30 MSMEs between January and May 2023. Data collected through questionnaires was analyzed with Statistical Package for Social Sciences, examining three independent variables: ethicality, Halal investment and prohibition of riba, in relation to MSME performance.
Findings
The results revealed significant relationships between these variables and MSME performance. Prohibition of riba (r = 0.296, n = 86, p = 0.006), Halal investments (r = 0.308, n = 86, p = 0.004) and ethical principles (r = 0.283, n = 86, p = 0.008) all exhibited a statistically significant relationship. Regression analysis with R = 0.405, R2 = 0.164 and adjusted R2 = 0.134 indicated that all hypothesized variables were significant predictors of MSME performance. Based on findings, this study rejected the null hypothesis, confirming a moderately positive and significant relationship between Islamic financial principles and MSME performance.
Originality/value
This study underscores the importance of active involvement from key stakeholders such as the Uganda Halal Bureau, Uganda Muslim Supreme Council, Islamic financial institutions and government agencies in integrating robust support mechanisms for MSMEs into their strategic frameworks. Such efforts could enhance Uganda’s economic landscape, aligning with the experiences of Malaysia and Indonesia in leveraging Islamic principles for economic growth.

Abstract
Purpose
The purpose of this study is to explain predictors that discriminate users’ preferences for online health services, focusing on a downtown area in a developing country.
Design/methodology/approach
Drawing on rational choice theory (RCT), the authors test a model that links the frequency of online health service usage to access-activators and access-inhibitors. Multivariate analysis of variance (MANOVA) and the discriminant analysis model were used to analyze data from a sample of 215 internet users.
Findings
Results confirm the significance of responsiveness, user’s attitude, accessibility and perceived ease of use, indicating their discriminating role in the usage of online health services.
Research limitations/implications
The study demonstrates the relevance of RCT in measuring perceived online health service quality in an emerging context. Future research should consider the influence of electronic health (eHealth) literacy, norms and trustworthiness to increase the generalizability of the findings.
Practical implications
The findings of this study can help enhance the eHealth service quality by encouraging service providers to improve the interactivity and ease of use of their platforms, thus delivering value to both consumers and firms and improving the well-being of the society at large.
Originality/value
Few existing studies draw attention to access-activators and access-inhibitors to predict users’ preferences for online health services. This study shows the applicability of RCT in preparing the instrumental dimensions of online health service quality.

Abstract
Purpose
This paper focuses on COVID-19 and human rights in the Global South. Controlling COVID-19 has become very challenging to the courtiers in the Global South and the Global North. Various restrictive measures, mainly lockdown, home quarantine, travel restrictions and social distancing have been taken in both Global North and South to control COVID-19. However, the lower-middle and poor class people of the Global South have suffered from these restrictive measures. Thus, this paper aims to explore the human rights issues of the Global South during COVID-19.
Design/methodology/approach
This study is a qualitative research based on secondary materials. It includes relevant scholarly articles, news reports and various reports from different national and international organizations. It critically reviews the current literature related to the topic to develop a theoretical understanding of human rights and public health in general and human rights challenges in COVID-19 in the Global South in particular. Existing international human rights principles in the case of public health were reviewed and discussed to identify the links between human rights laws in public health perspectives. Contents analysis was carried out to identify the relevant themes on the issues of human rights in response to the COVID-19 pandemic.
Findings
This paper finds that universal guidelines to control COVID-19 challenged the human rights norms, which impacts the enjoyment of human rights in the Global South. The human rights of the people in the Global South were undermined in the response to the control of COVID-19.
Originality/value
This paper is a significant study on the issues of human rights in public health emergencies. It addresses how the human rights of the vulnerable people in the Global South are undermined in the global pandemic response, which can be useful for the countries in the Global South for ensuring better human rights-based responses in the future.

Abstract
Purpose
This study aims to analyse the impact of love of money, personality traits and peer influence on the ethical behaviour of graduate accounting students at the University of Ghana Business School.
Design/methodology/approach
This study used a quantitative research approach to sample postgraduate accounting students who completed a self-administered questionnaire on the variables of interest. Using partial least square–structural equation modelling, the hypothesized relationships were examined based on 328 appropriate responses received for the questionnaire.
Findings
The empirical findings suggest that peer influence and personality trait, extraversion positively and significantly influence unethical behaviour, whereas the personality traits, agreeableness and openness to experience have a negative and significant relationship with unethical behaviour. The study, however, does not find support for the hypothesized relationships between the love of money, personality traits (conscientiousness, neuroticism) and unethical behaviour.
Originality/value
The study contributes to the literature on unethical behaviour, highlighting how decision-making factors such as love of money, peer influence and personality traits, respectively, influence unethical behaviour explained by the self-justification concept under the social cognitive and moral reasoning theory. This could aid these potential managers in seeking higher reviews on ethical dilemmas. It could also aid the professional body and academics in Ghana particularly to intensify ethical education for students of the profession.

Abstract
Purpose
This research is about embedding service-based supply chain management (SCM) concepts in the education sector. Due to Canada's competitive education sector, the authors focus on Canadian universities.
Design/methodology/approach
The authors develop a framework for evaluating and forecasting university performance using data envelopment analysis (DEA) and artificial neural networks (ANNs) to assist education policymakers. The application of the proposed framework is illustrated based on information from 16 Canadian universities and by investigating their teaching and research performance.
Findings
The major findings are (1) applying the service SCM concept to develop a performance evaluation and prediction framework, (2) demonstrating the application of DEA-ANN for computing and predicting the efficiency of service SCM in Canadian universities, and (3) generating insights to enable universities to improve their research and teaching performances considering critical inputs and outputs.
Research limitations/implications
This paper presents a new framework for universities' performance assessment and performance prediction. DEA and ANN are integrated to aid decision-makers in evaluating the performances of universities.
Practical implications
The findings suggest that higher education policymakers should monitor attrition rates at graduate and undergraduate levels and provide financial support to facilitate research and concentrate on Ph.D. programs. Additionally, the sensitivity analysis indicates that selecting inputs and outputs is critical in determining university rankings.
Originality/value
This research proposes a new integrated DEA and ANN framework to assess and forecast future teaching and research efficiencies applying the service supply chain concept. The findings offer policymakers insights such as paying close attention to the attrition rates of undergraduate and postgraduate programs. In addition, prioritizing internal research support and concentrating on Ph.D. programs is recommended.

Abstract
Purpose
According to the previous research, bioconvection has been recognized as an important mechanism in current engineering and environmental systems. For example, researchers exploit this mechanism in modern green bioengineering to develop environmentally friendly fuels, fuel cells and photosynthetic microorganisms. This study aims to analyse how this type of convection affects the flow behaviour and heat transfer performance of mixed convection stagnation point flow in alumina-copper/water hybrid nanofluid. Also, the impact of a modified magnetic field on the boundary layer flow is considered.
Design/methodology/approach
By applying appropriate transformations, the multivariable differential equations are transformed into a specific sort of ordinary differential equations. Using the bvp4c procedure, the adjusted mathematical model is revealed. Once sufficient assumptions are provided, multiple solutions are able to be produced.
Findings
The skin friction coefficient is declined when the nanoparticle concentration is increased in the opposing flow. In contrast, the inclusion of aligned angles displays an upward trend in heat transfer performance. The presence of several solutions is established, which simply leads to a stability analysis, hence verifies the viability of the initial solution.
Originality/value
The current findings are unique and novel for the investigation of mixed bioconvection flow towards a vertical flat plate in a base fluid with the presence of hybrid nanoparticles.

Abstract
Purpose
This study aims to examine the determinants of ethical decision-making (EDM) of professional accountants in Sri Lanka, drawing on Rest’s (1986) four-component EDM model. The level of corporate collapses and fraud, coupled with the high level of corruption in Sri Lanka, has highlighted the importance and the timely nature of this research in the EDM processes of Sri Lankan accountants.
Design/methodology/approach
Data was collected from a sample of 315 accountants through a questionnaire survey that included four written ethical vignettes and was analysed using partial least square-structural equation modelling techniques.
Findings
The findings revealed a significant relationship between ethical awareness and ethical judgement, providing support for Rest’s model. However, the study does not support Rest’s model on the direct relationship between ethical judgement and ethical intention. Intrinsic religiosity and moral intensity significantly influenced the ethical awareness of accountants. Several determinants including accountants’ age, education, intrinsic religiosity, organisational ethical culture, familiarity with the professional ethical code and moral intensity influenced ethical judgement. However, the findings did not report any significant relationships between the study’s variables and ethical intention.
Originality/value
The study adds to the existing literature by providing a bigger picture of how various determinants work together in one EDM model and demonstrating that the EDM of accountants is multifaceted. The new finding on an insignificant relationship between ethical judgement and ethical intention implies that the Rest’s EDM process may be mediated and moderated by other constraints blocking accountants’ intention to act due to various pressures in a corrupt society, Sri Lanka, where accountants operate.

Abstract
Purpose
In this study, the authors analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.
Design/methodology/approach
The study used a mix of wavelet-based approaches, including continuous wavelet transformation and discrete wavelet transformation. The analysis used data from the Geopolitical Risk index (GP{R), Dow Jones Sukuk index (SUKUK), Dow Jones Islamic index (DJII), Dow Jones composite index (DJCI), one of the top crude oil benchmarks which is based on the Europe (BRENT) (oil fields in the North Sea between the Shetland Island and Norway), and Global Gold Price Index (gold) from May 31, 2012, to June 13, 2022.
Findings
The results of the study indicate that during the COVID-19 and Russia–Ukraine conflict period geopolitical risk (GPR) was in the leading position, where BRENT confirmed the lagging relationship. On the other hand, during the COVID-19 pandemic period, SUKUK, DJII and DJCI are in the leading position, where GPR confirms the lagging position.
Originality/value
The present study is unique in three respects. First, the authors revisit the influence of GPR on global asset markets such as Islamic stocks, Islamic bonds, conventional stocks, oil and gold. Second, the authors use the wavelet power spectrum and coherence analysis to determine the level of reliance based on time and frequency features. Third, the authors conduct an empirical study that includes recent endogenous shocks generated by health crises such as the COVID-19 epidemic, as well as shocks caused by the geopolitical danger of a war between Russia and Ukraine.
Highlights
We analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.
The results of the wavelet-based approach show that Dow Jones composite and Islamic indexes have observed the highest mean return during the study period.
GPR and BRENT are estimated to have the highest amount of risk throughout the observation period.
Dow Jones Sukuk, Islamic and composite stock show similar trend of volatility during the COVID-19 pandemic period and comparatively gold observes lower variance during the COVID-19 pandemic and Russia–Ukraine conflict.
