Data-driven wall modeling for LES involving non-equilibrium boundary layer effects
Authors: Radhakrishnan Sarath , Calafell Joan , Miró Arnau , Font Bernat , Lehmkuhl Oriol 
Published: August 2024

Purpose
Wall-modeled large eddy simulation (LES) is a practical tool for solving wall-bounded flows with less computational cost by avoiding the explicit resolution of the near-wall region. However, its use is limited in flows that have high non-equilibrium effects like separation or transition. This study aims to present a novel methodology of using high-fidelity data and machine learning (ML) techniques to capture these non-equilibrium effects.

Design/methodology/approach
A precursor to this methodology has already been tested in Radhakrishnan et al. (2021) for equilibrium flows using LES of channel flow data. In the current methodology, the high-fidelity data chosen for training includes direct numerical simulation of a double diffuser that has strong non-equilibrium flow regions, and LES of a channel flow. The ultimate purpose of the model is to distinguish between equilibrium and non-equilibrium regions, and to provide the appropriate wall shear stress. The ML system used for this study is gradient-boosted regression trees.

Findings
The authors show that the model can be trained to make accurate predictions for both equilibrium and non-equilibrium boundary layers. In example, the authors find that the model is very effective for corner flows and flows that involve relaminarization, while performing rather ineffectively at recirculation regions.

Originality/value
Data from relaminarization regions help the model to better understand such phenomenon and to provide an appropriate boundary condition based on that. This motivates the authors to continue the research in this direction by adding more non-equilibrium phenomena to the training data to capture recirculation as well.
Is return on investment the appropriate tool for healthcare quality improvement governance?
Authors: Thusini S'thembile , Soukup Tayana , Henderson Claire 
Published: August 2024

PurposeIn this article, we outline our views on the appropriateness and utility of Return on Investment (ROI) for the evaluation of the value of healthcare quality improvement (QI) programmes.Design/methodology/approachOur recent research explored the ROI concept and became the genesis of our viewpoint. We reflect on our findings from an extensive research project on the concept of ROI, involving a multidisciplinary global systematic literature review, a qualitative and Delphi study with mental healthcare leaders from the United Kingdom National Health Service. Research participants included board members, clinical directors and QI leaders. Our findings led to our conclusions and interpretation of ROI against the broad QI governance. We discuss our views against the predominant governance frameworks and wider literature.FindingsROI is in-line with top-down control governance frameworks based in politics and economics. However, there is evidence that to be of better utility, a tool for the assessment of the value of QI benefits must include comprehensive benefits that reflect broad monetary and non-monetary benefits. This is in-line with bottom-up and collaborative governance approaches. ROI has several challenges that may limit it as a QI governance tool. This is supported by wider literature on ROI, QI as well as modern governance theories and models. As such, we question whether ROI is the appropriate tool for QI governance. A more pragmatic governance framework that accommodates various healthcare objectives is advised.Practical implicationsThis article highlights some of the challenges in adopting ROI as a QI governance tool. We signal a need for the exploration of a suitable QI governance approach. Particularly, are healthcare leaders to be perceived as “agents”, “stewards” or both. The evidence from our research and wider literature indicates that both are crucial. Better QI governance through an appropriate value assessment tool could improve clarity on QI value, and thus investment allocation decision-making. Constructive discussion about the utility and appropriateness of ROI in the evaluation of healthcare QI programmes may help safeguard investment in effective and efficient health systems.Originality/valueThe article raises awareness of QI governance and encourages discussions about the challenges of using ROI as a tool for healthcare QI governance.
Identifying the success factors for TQM implementation among automotive spare parts companies using analytic hierarchy process (AHP): evidence from Palestine
Authors: Zaid Ahmed Adnan , Saleh Yahya , Tomeh Alaa Jawdat 
Published: August 2024

PurposeThis paper aims to identify the success factors (SFs) for total quality management (TQM) implementation in automotive spare parts companies to improve their business performance. It also intends to rank these factors in a hierarchical structure in descending order of their criticality.Design/methodology/approachIn this study, a significant number of automotive spare parts companies were extensively surveyed to ascertain the contributions made by various factors toward the successful deployment of TQM practices. The collective and individual evaluation and ranking of the SFs were determined using the analytical hierarchy process (AHP) approach to develop the framework based on the prioritisation of the identified SFs.FindingsThe findings of the study show that five success factors, namely, internal environment, top management involvement, process management, supplier management and external environment, were ranked as critical factors with a total weight of 49.2%. Nine success factors, namely, employee training, teamwork, customer satisfaction, continuous improvement, communications, using new technologies, zero-defect processes, employee empowerment and benchmarking, were ranked as important with a total weight of 39.1%. The last five success factors, namely, strategic planning, quality policy, employee satisfaction, self-assessment and cost of quality, were ranked as minor factors with a total weight of 11.7%.Originality/valueThe current study adds to the existing body of knowledge for scholars and practitioners of TQM by specifically focusing on identifying and categorising the critical SFs for TQM implementation. The 19 categorised critical SFs have been used to construct a framework for TQM implementation in the Palestinian automotive spare parts companies. Such a framework would offer a comprehensive overview of the SFs, their categories, significance and priorities within a TQM environment in the automotive spare parts companies.
Assessing the role of consumer innovativeness and government incentives in enhancing the intention to install solar photovoltaic panels in Vietnam
Authors: Tran Khoa Tien , Le Nga , Nguyen Phuong V. 
Published: August 2024

Purpose
In response to increasing concerns about climate change and evolving public policies, consumer behaviour and attitudes are shifting towards the adoption of renewable energy solutions like photovoltaic (PV) panel systems. This study aims to address this shift by developing a conceptual framework grounded in the Unified Theory of Acceptance and Use of Technology and Diffusion of Innovation theory. The framework identifies and analyses the factors influencing Vietnamese consumers’ decisions to install PV panels, focusing on the roles of consumer innovativeness, government incentives and social influence. By examining these dynamics, this study offers insights to inform policy in promoting renewable energy adoption.

Design/methodology/approach
Data from 339 Vietnamese households were analysed using SmartPLS 3.0 to test the proposed hypotheses. A structured questionnaire survey focused on consumer innovativeness, government incentives and social influence. The partial least squares structural equation modelling approach was used to evaluate the relationships between constructs.

Findings
The findings indicate that consumer innovativeness significantly predicts knowledge, sustainable lifestyles and attitudes towards solar PV panels. Moreover, household attitudes are influenced by government incentives and knowledge, but not by sustainable lifestyles. Crucially, the intention to install solar PV panels among Vietnamese households is positively affected by facilitating conditions, government incentives and social influence.

Originality/value
The results can assist government officials and policymakers in emerging markets in devising strategies to alleviate environmental burdens and facilitate a shift towards sustainability. Furthermore, by understanding the factors impacting the residents’ intention, public communication can be improved to raise awareness of environmental concerns and sustainable lifestyles, which results in the encouragement of the purchase and installation intention of solar panels.
Institutionalisation of CSR stakeholders: an analysis of the Indian corporate sector in the mandatory regime
Authors: Bhatia Aparna , Dhawan Amandeep 
Published: August 2024

Purpose
This study aims to analyse the deployment of mandatory corporate social responsibility (CSR) expenditure incurred by Indian corporate sector, under various development heads as specified by CSR statutes in India.

Design/methodology/approach
The thematic distribution of mandatory CSR expenditure is calculated on a large sample of top 500 Bombay Stock Exchange-listed companies in India over a time span of seven years from 2014 to 2015 till 2020–2021. The money spent on each of the specified stakeholders is extracted from the annual reports of the sampled companies to calculate the average expenditure under each of the development heads.

Findings
The findings indicate that the distribution of CSR expenditure by Indian companies into various development heads is unbalanced. Some of the heads such as “Education”, “Healthcare”, “Development Projects”, “Employment” and “Environment” attract more CSR contributions, whereas some other equally important heads such as “Art & Culture”, “Sports”, “Armed Forces” and “Technology Incubators” have comparatively received much less contributions in all the years of assessment. However, during the times of COVID, Indian companies proactively contributed to combat the virus so much so that “COVID-19 Relief” received all-time high contributions among all the development indicators.

Practical implications
The institutionalised back up has replaced the randomness in stakeholders’ approach followed by Indian companies. To ensure the balanced development of the country, the disproportionate contribution into various development heads in all the years of mandatory CSR era calls for further assessment of CSR guidelines issued by the Ministry of Corporate Affairs (MOCA).

Originality/value
This study gives significantly novel insights into the CSR literature by comprehensively analysing the deployment of mandatory CSR funds into various development heads as specified by MOCA in India.

Tribological performance of di-n-octyl sebacate synthesized with carboxylated nano-MoS2/sericite as catalyst
Authors: Gong Junjie , Li Zhixiang , Lin Qingqing , Hu Kunhong 
Published: August 2024

Purpose
This study aims to explore the synthesis and tribological performances of di-n-octyl sebacate (DOS) synthesized with spherical nano-MoS2/sericite (SMS) and carboxylated SMS (CSMS) as catalysts.

Design/methodology/approach
SMS and CSMS were used as esterification catalysts to synthesize DOS from sebacic acid and n-octanol. The two catalysts were in situ dispersed in the synthesized DOS after the reaction to form suspensions. The tribological performances of the two suspensions after 20 days of storage were studied.

Findings
CSMS was more stably dispersed in DOS than SMS, and they reduced friction by 55.6% and 22.2% and wear by 51.3% and 56.5%, respectively. Such results were mainly caused by the COOH on CSMS, which was more conducive to improving the dispersion and friction reduction of CSMS than wear resistance. Another possible reason was the difference between the dispersion amounts of CSMS and SMS in DOS. The sericite of SMS was converted into SiO2 to enhance wear resistance, while that of CSMS only partially generated SiO2, and the rest still remained on the surface to reduce friction.

Originality/value
This work provides a more effective SMS catalytical way for DOS synthesis than the traditional inorganic acid catalytical method. SMS does not need to be separated after reaction and can be dispersed directly in DOS as a lubricant additive. Replacing SMS with CSMS can produce a more stable suspension and reduce friction significantly. This work combined the advantages of surface carboxylation modification and in situ catalytic dispersion and provided alternatives for the synthesis of DOS and the dispersion of MoS2-based lubricant additives.
The possibility of establishing an endowment (Waqf) from the Islamic financial institutions’ provisioned funds in the United Arab Emirates
Authors: Bessais Sofien , Zakariyah Habeebullah , Mohd Noor Azman 
Published: August 2024

Purpose
Islamic financial institutions (IFIs) can gather provisioned funds from various sources, but they are prohibited from incorporating these funds into their profits or using them for personal gain as they are considered illegitimate income. Instead, IFIs are required to allocate these funds to charitable purposes. This study aims to examine the potential establishment of a Waqf (an Islamic alternative for endowment) using the provisioned funds of IFIs in the United Arab Emirates (UAE) by analyzing its Shariah perspective, utility and viability.

Design/methodology/approach
This research uses an information-gathering approach, gathering data from books, articles, journals and websites to illuminate the Shariah perspective of endowing provisioned funds. Additionally, it draws upon interviews with experts in Waqf and Islamic banking and finance to grasp the potential and viability of establishing a Waqf from provisioned funds in the UAE.

Findings
Establishing a Waqf using provisioned funds is permissible. Although Waqf is always advantageous, in the current situation, endowing Islamic financial institutions' provisioned funds will not adequately address societal needs in the UAE. This is because the majority of annual returns on UAE Waqf investments are low compared to the amount invested, and there is an urgency to disburse these funds to those in need. If these needs are identified and met using Zakat and other charitable funds, a Waqf can be created from provisioned funds and prove beneficial. However, the authors have suggested some proposals to establish a relevant Waqf from provisioned funds that satisfy the required conditions and address the societal needs of the UAE. They concluded that creating a Waqf school would be the best suggestion.

Research limitations/implications
The scope of this study is limited to examining the use of IFIs' provisioned funds to establish a Waqf in the UAE. Furthermore, the findings and conclusions of this study may be applicable only to the UAE and may not be universally applicable to other countries.

Practical implications
Proposed initiatives to create a “Cash Waqf” fund and a “Waqf School” using provisioned funds are anticipated to bring about immediate positive changes for the underprivileged and the wider UAE community. Furthermore, the sustainable establishment of any Waqf could greatly benefit society by addressing all societal needs through Zakat and charitable contributions.

Originality/value
To the best of the authors’ knowledge, this is the first study to explore the potential and practicality of creating a Waqf using provisioned funds from IFIs in the UAE.
Impact of exchange rate volatility on export of small economies
Authors: Rojid Tasneem , Rojid Sawkut 
Published: August 2024

PurposeThis paper examines the extent to which exchange rate volatility (ERV) is crucial for small island economies. These economies by their very nature and size tend to be net importers and highly dependent on trade for their economic survival. The island of Mauritius is used as a case study.Design/methodology/approachA GARCH model has been utilized using yearly data for the period 1993–2022. The ARDL bounds cointegration approach has been used to determine the long run relationship between exchange rate volatility and the performance of exports. The ECM-ARDL model has been used to estimate the short-run relationships, that is the speed of adjustments between the variables under consideration.FindingsThe findings reveal that exchange rate volatility has a positive and significant effect on exports in the short run as well as in the long run. The study also finds out that export has a long-term relationship with world GDP per capita. Both the presence and degree of exchange rate volatility are important aspects for consideration in policy making.Originality/valueThe literature gap that this study attempts to close is one related to global impacts within the recent time horizon. Recently, numerous important events shaped the financial and economic landscape globally, including but not limited to the financial crisis of 2008 and the COVID-19 pandemic in 2019. Both these events stressed the global volume of trade and the exchange rate markets, and these events affects small islands comparatively more given their heavy dependence on international trade for economic development, albeit economic survival.
The aspects of behavioral finance with new insights: an analysis of individual investors at Pakistan Stock Exchange (PSX)
Authors: Munir Sara , Chishti Mazhar Farid , Bashir Rizwana 
Published: August 2024

PurposeThe cognitive biases exhibited by investors could hinder their capacity for logical reasoning and impact their perception and reaction to information when making financial choices. So, this study was done to identify the behavioral biases that hinder investors' sound decision-making at the Pakistan Stock Exchange (PSX).Design/methodology/approachA cross-sectional study was undertaken employing a causal research design approach. Questionnaires were administered to individual investors of the PSX as the data collection methodology. The data were subsequently analyzed through the utilization of the Smart PLS Structural Equation Modeling (SEM) technique.FindingsThe results suggest that information factors and cognitive biases, namely home bias, geographical bias, investor sentiment, salience, and over/under reaction have a positive association with the investors' choices at PSX.Research limitations/implicationsThe study’s emphasis is on the impact of behavioral biases on individual investors only, even though such biases also influence the investment decisions of institutional investors.Practical implicationsThe study holds implications for scholars engaged in the field of behavioral finance as well as professionals involved in the stock market, particularly those interacting with individual investors and personal finance. Additionally, the current study will take into account investors, financial advisors, practitioners, policymakers, investment experts, stakeholders or target groups, etc. to support various groups in their professional activity and to help them overcome such biases that influence their sound decision-making power.Originality/valueThe innovative aspect of this research is its ability to advance the understanding of the conceptual underpinnings and social structure of behavioral biases by critically analyzing the body of prior research and adding value to the existing body of literature on behavioral finance in Pakistan by investigating the combined impact of never-studied variables, i.e. geographical bias and information variables, understudied behavioral variables, i.e. home bias and salience and studied variables, i.e. investor sentiment and over/under reaction on individual investor investment decisions at PSX.
Teaching and learning in business schools post-pandemic: a digital future
Authors: Zizka Laura , Probst Gaby 
Published: August 2024

Purpose
In 2018, a group of higher education institutions (HEIs) in Switzerland started discussing the future of education. With the COVID-19 pandemic, many of their initial ideas and solutions were tested in the unpredictable, emergency online setting. This study aims to use student and faculty member perceptions to outline the future of higher education.

Design/methodology/approach
This research is based on eight surveys from students and faculty members at one Swiss HEI in business studies. While many previous studies focus on one group or one moment in time, this study examines the future of business education from both perspectives and traces the responses throughout the pandemic.

Findings
Teaching and learning strategies and perceptions evolved during the COVID-19 pandemic. Nonetheless, despite the potential, many HEIs simply reverted to normal instead of adapting to the “new normal”. Conversely, some HEIs have continued using the same exercises and tools that were used in the emergency remote pandemic-mode, without adapting or reflecting on the current learning environment. Based on the findings, both students and faculty members have increased their interest and proficiency in using digital tools although the students remained more open toward the opportunities of digital teaching and learning.

Originality/value
Based on the results, this study offers a model for the future of education that HEIs could implement when moving forward, whether on campus or online.
