Abstract
Purpose
The aim of this paper is to assess the ability of a stress-blended eddy simulation (SBES) turbulence model to predict the performance of a three-straight-bladed vertical axis wind turbine (VAWT). The grid sensitivity study is conducted to evaluate the simulation accuracy.
Design/methodology/approach
The unsteady Reynolds-averaged Navier–Stokes equations are solved using the computational fluid dynamics (CFD) technique. Two types of grid topology around the blades, namely, O-grid (OG) and C-grid (CG) types, are considered for grid sensitivity studies.
Findings
With regard to the power coefficient (Cp), simulation results have shown significant improvements of predictions using compared to other turbulence models such as the k-e model. The Cp distributions predicted by applying the CG mesh are in good agreement with the experimental data than that by the OG mesh.
Research limitations/implications
The current study provides some new insights of the use of SBES turbulence model in VAWT CFD simulations.
Practical implications
The SBES turbulence model can significantly improve the numerical accuracy on predicting the VAWT performance at a lower tip speed ratio (TSR), which other turbulence models cannot achieve. Furthermore, it has less computational demand for the finer grid resolution used in the RANS-Large Eddy Simulation (LES) “transition” zone compared to other hybrid RANS-LES models.
Originality/value
To authors’ knowledge, this is the first attempt to apply SBES turbulence model to predict VAWT performance resulting for accurate CFD results. The better prediction can increase the credibility of computational evaluation of a new or an improved configuration of VAWT.

The purpose of this study is to develop an ecosystem-based DRR concept and explore how far the concept can be applied in a disaster-management context.
Abstract
Purpose
The purpose of this study is to develop an ecosystem-based DRR concept and explore how far the concept can be applied in a disaster-management context.
Design/methodology/approach
The authors used the ecosystem concept established by Tsujimoto et al. (2018) as the foundation of this study. They then conducted a literature search to adapt the ecosystem concept to fit the context of disaster management. Thus, they developed an ecosystem-based DRR concept. They used a case study method to test whether the adapted ecosystem concept can be applied to examine a real-life case of disaster management. For data collection, they used qualitative methods; a semi-structured interview with practitioners and other actors involved in disaster-management practice as well as document review. For data analysis, they used thematic analysis to find themes within the data.
Findings
By using this concept, the authors found some actors fulfil their role in the ecosystem toward the DRR effort, some actors are ill-equipped, and some actors are actively working against DRR effort. There are also implementation challenges, as numerous programs are only halfway done due to a lack of resources. However, the main problems of this disaster can be summarized into three categories: technical problems, socio-economic problems and law-enforcement problems. All three problems need to be addressed altogether because even neglecting only one problem would lead to a flawed solution.
Research limitations/implications
One of the limitations is the respondents' bias. This research aims to find out their part, or more accurately what they are representative of, regarding disaster management for forest and land fire case. As some of the questions may reveal unflattering action or may even hurting their credibility, respondents might not have provided an entirely honest answer. Another limitation is the differing respondents' roles within the disaster. As each of the respondents is a representative of an actor in disaster management, they all have different traits. Thus, this situation makes it challenging to produce similar quality and quantity data for each of them.
Practical implications
As concluded, the ecosystem-based DRR concept can be used as a framework to examine a real-life case of disaster management. It can be utilized to explain roles, relationships and the whole network of disaster-management actors. The authors hope that this concept could help decision-makers in designing their policies.
Social implications
The main problems of this disaster can be summarized into three categories: technical problems, socio-economic problems and law-enforcement problems. All three problems need to be addressed altogether for even neglecting only one problem would lead to a flawed solution. However, the yearly reoccurrences of fires and the widespread of illegal and dangerous practice, slash and burn agriculture, are evidence that the government mishandles the other two problems. There is a need for reform within legal institutions and government's treatment regarding local farmers. There is a need for trust, cooperation and synergy between disaster-management actors.
Originality/value
The ecosystem concept has been used widely in the field of management of technology and innovation. However, while ecosystem concept is commonly used in the management of technology and innovation, it is rarely used in a disaster-management context.

Abstract
Purpose
This study aims to examine the effect of entrepreneurial intention and attitude towards knowledge sharing on new business creation by comparing two generations, Y generation (millennials) and Z generation (post-millennial). In addition, the current study uses a social cognitive theory as a point of departure to test the research hypotheses.
Design/methodology/approach
This study deploys a quantitative approach (hypothetic-deductive approach) by surveying 300 respondents representing the two Indonesian generations. The questionnaire consisting of demographic items (age, education, etc.) and variables was the primary research instrument. This study used regression analysis, a Wald test for examining the proposed hypotheses and a t-test to provide a deeper analysis of the findings.
Findings
Findings from the current study show that Gen Y is still seeking a balance for their learning sources by involving in their social environments as well as exploring the digital world. In contrast, Gen Z is much more dominant in the independence to learn things that interest them. They have less dependency on social patrons but prioritise themselves as the leading model.
Practical implications
The findings of this study provide practical implications for higher education institutions in the development of entrepreneurship education to achieve learning effectiveness.
Originality/value
This study aims to contribute by providing empirical evidence in the effect of entrepreneurial orientation and attitude towards knowledge sharing on new venture creation with particular reference to Gen Y and Gen Z, suggested by previous studies. Although Gen Y and Gen Z are digital natives, this study provides insight into a shift in the characteristic of two generations, as also found in comparison to previous generations, such as Baby-Boomer vs Gen X and Gen X vs Gen Y. This study proclaims the need to adjust organisational theories to enable them to explain the shifting phenomena at the micro and macro level for every generation. Exploratory research to better understand the characteristics of a generation in other settings is a crucial proposal proposed by this study.

Abstract
Purpose
The high rate of ship casualties demands serious attention. Earlier studies have yet to integrate several scenarios in an experiment. This research aims to determine damage to a ship's hull that is assumed to have been stranded due to being hit by a rock under the sea.
Design/methodology/approach
This scenario was analyzed by conducting a penetration test simulation using the ANSYS LS DYNA. Modeling was carried out with core, speed, indenter shape and indenter angle variations. The test is carried out by moving the indenter against the plate until the plate is damaged.
Findings
The results of this research show that the round indenter gave the best results in testing, while changes in speed below 1.5 m/s did not significantly affect the results. The contact angle of the indenter to the panel is directly proportional to the damage to the panel, and core X has the best results in the test.
Originality/value
This work presented several proposed eccentric sandwich panels to calculate their performance against impact loading. The detailed geometry for future reference is presented, while the indenter-panel interactions are validated based on experimental work.

Abstract
Purpose
The purpose of this paper is to investigate the influence of trust and perceived risk on investment willingness considering the bidirectional relationship between trust and perceived risk in peer-to-peer (P2P) lending.
Design/methodology/approach
Data were collected from a leading Chinese P2P platform, PPDAI.com. In total, 328 valid responses were received and analyzed using structural equation modeling (SEM).
Findings
The results show that the influence of trust on investment willingness is significant, whereas that of perceived risk is insignificant. The results also indicate that platform reputation has a positive effect on trust, and the quality of alternatives is positively associated with perceived risk. In addition, the bidirectional perspective should be preferred to cope with the bidirectional relationship between trust and perceived risk in P2P lending.
Originality/value
This study extends existing research on the influence of trust and perceived risk on investment willingness from a bidirectional perspective, which has not been addressed in the P2P lending context. In addition, this research enriches the current literature about trust and perceived risk by providing more evidence that the relationship between trust and perceived risk is bidirectional and thus the bidirectional model should be preferred. For practice, the study suggests that managers can earn trust and reduce the perceived risk of lenders by continuously providing high-quality products, services and enhancing platform reputation, ultimately improving their investment willingness.

Abstract
Purpose
FinTech offers numerous prospects for significant enhancements and fundamental changes in financial services. However, along with the myriad of benefits, it also has the potential to induce risks to individuals, organisations and society. This study focuses on understanding FinTech developers’ perspective of the dark side of FinTech.
Design/methodology/approach
This study conducted semi-structured interviews with 23 Nigerian FinTech developers using an exploratory, inductive methodology The data were transcribed and then thematically analysed using NVivo.
Findings
Three themes – customer vulnerability, technical inability and regulatory irresponsibility – arose from the thematic analysis. The poor existing technological infrastructure, data management challenges, limited access to data and smartphone adoption pose challenges to a speedy integration of FinTech in the country, making customers vulnerable. The lack of privacy control leads to ethical issues. The lack of skilled developers and the brain drain of good developers present additional obstacles to the development of FinTech in Nigeria.
Research limitations/implications
FinTech operation in a developing country differs from that in developed countries with better technological infrastructure and institutional acceptance. This study recognises that basic banking operations through FinTech are still not well adopted, necessitating the need to be more open-minded about the global practicalities of FinTech.
Practical implications
FinTech managers, banks and policymakers can ethically collect consumer data that can help influence customer credit decisions, product development and recommendations using the mobile app and transaction history. There should be strict penalties on FinTech for selling customers’ data, sending unsolicited messages or gaining unnecessary access to the customer’s contact list. FinTech can offer to educate consumers about their financial management skills.
Originality/value
Whereas other studies have focused on the positive aspects of FinTech to understand client perceptions, this study offers new insights into the dark side of FinTech by analysing the viewpoints of FinTech developers. Furthermore, the study is based in Nigeria, an emerging economy adopting FinTech, adding a new dimension to the body of knowledge.

Abstract
Purpose
The main value in a culture of tolerance is wasatiyyah. The fragility of relationships and misunderstanding between Muslim and non-Muslim communities occurs when attention to values of tolerance which need more attention on moderation was not practiced especially in the life of a new Muslim convert community. Thus, the practice of moderation is one mechanism proposed by the government to ensure a harmonious continuation of life in a religious community can be achieved. For that, a qualitative study design was used to describe the current status of a phenomenon that occurs among new Muslim converts. The purposive sampling method is used to determine the applications of wasatiyyah in new Muslims’ life tolerance at Kota Kinabalu (East Malaysia) and Kuala Terengganu (West Malaysia). Although the study was conducted at two different locations, there is a relationship between religious phenomena that occur in the new Muslims community in Malaysia. The purpose of this study is to see the practical concept of moderation in the life of new Muslims and their relation with Muslims and non-Muslims. The results showed that the value of moderation was applied in the aspect of tolerance. The application of Wasatiyyah in practice of tolerance had helped non-Muslims family members to change their attitudes and perception towards Islam. This study suggests the values of wasatiyyah in the life of religious tolerance, need to be nourished especially in multiethnic society when sharing a living places, education and employment for better social development as well as a well-being pluralistic society.
Design/methodology/approach
The study was conducted through descriptive data qualitative methods. Purposive sampling was used which refers to a group that has the characteristics of samples required by researchers (Mohd Najib Abdul Ghafar 2003). This study applies the method of in-depth interview with the selected new Muslims around Kota Kinabalu (representing East Malaysia) and around Kuala Terengganu (representing Peninsular Malaysia/West Malaysia). Thus, data accumulation involves new Muslims (new Converts) from various ethnics (Sabahan and Sarawakian) which comprise Kadazandusun, Murut, Rungus, Sino and Iban. Secondly, those are from the Peninsular Malaysia which includes Chinese and Indian. Whereas in Kuala Terengganu, data accumulation involves new Muslims from various ethnics (Chinese, Indian, Sarawakian and others). The result of the interview is shown through descriptive narratives which display the practice of tolerance in the form of supportive interaction from the non-Muslim families towards the new Muslims in Islamic lifestyle.
Findings
The concept of wasatiyyah has nurturing tolerance among Muslim, newly Muslim and non-Muslim as well as fostering harmony among the diverse ethnics in Malaysia. Based on the discussion, it was observed that the concept of wasatiyyah had a great influence on the relationship among Muslim, newly Muslim and non-Muslim, as it had a strong link with the value of akhlaq that have been embedded in the Muslim community. The wasatiyyah is the main element that shapes the relationship, and it is the results of interaction with social norms, for it has bred certain social values that include tolerance, compromise, modesty, respect and cooperation as transpired when they (Muslim and newly Muslim) interact among themselves or with other communities. Furthermore, the main goal for the concept is to maintain peace and built well-being in the society as well as bracing racial ties in Malaysia, especially among Muslim, newly Muslim and non-Muslim.
Originality/value
Tolerance is a culture that founded the co-existence of pluralistic society in Malaysia. The culture of tolerance can only be built if ethnic tolerance and religious tolerance is accepted as a common practice – Muslims and non-Muslims alike. The description of wasatiyyah in the practice of religious tolerance among the families of new Muslims is the platform towards the acculturation of tolerance in the societal life from different faith and ethnics. It can be said that the higher the tolerance of ethnic, the higher is the religious tolerance, which is manifested through the application of wasatiyyah between people from different religions. This situation is highlighted in the relations of Muslim, newly Muslim and non-Muslim in Sabah and Terengganu where the culture of tolerance is apparent in the life together. Extensive interaction through encounters, acquaintance and co-existence that shape the friendship, brotherhood and kinship is the best formula in nurturing the culture of tolerance in the pluralistic society of Malaysia. Perhaps, the concept of wasatiyyah may be implemented in the whole aspect of life in the context of Malaysia. It is because the term wasatiyyah has the main sources of Islamic epistemology as well as sustaining the well-being pluralistic society without destroying the differences.

Abstract
Purpose
Sharia-compliant financial technologies (Islamic fintech) are becoming increasingly popular among Muslims and non-Muslims. As the Islamic fintech landscape continues to grow and transform, it is crucial to understand the factors that influence the acceptance or adoption of Islamic fintech services from the past literature. Therefore, this paper aims to conduct a systematic literature review (SLR) to investigate and compile factors that could influence a user to adopt Islamic fintech.
Design/methodology/approach
The current study adopted the systematic literature review approach using Preferred Reporting Items for Systematic Reviews and Meta-Analyses technique to examine research on Islamic fintech adoption. A set of inclusion criteria was applied to filter out irrelevant documents and ensure the selection of only the most relevant ones. The criteria were limited to quantitative journals published in English between 2012 and 2022, as identified in Scopus outlets.
Findings
Despite the existence of various theoretical frameworks, the technology acceptance model and Unified Theory of Acceptance and Use of Technology 2 frameworks have gained prominence as the most frequently applied frameworks in examining Islamic fintech adoption. In addition, trust is the most important self-developed construct for the adoption of Islamic Fintech.
Research limitations/implications
The current study does not segregate the intention, actual usage and retention, as the author is interested in understanding the overall adoption of Islamic fintech services. To obtain more specific analysis results, future research could potentially separate the three types of adoption exposure, i.e., consumer acceptance, intention and retention. Next, future studies can also expand their analysis and gain a better understanding of the research topic by exploring alternative data sources such as Web of Science, ERA or JSTOR.
Originality/value
To the best of the author’s knowledge, this study makes a significant contribution to the literature by providing the first systematic literature review of factors influencing fintech adoption from an Islamic perspective.
