An increase in outsourcing of consultancy services has been observed during procurement and delivery of public-sector infrastructure projects. However, the incidence of project failure has continued unabated despite this shift by public-sector entities. Also, there appears to be limited literature focussed on seeking to provide the rationale governing the decision to outsource or insource consultancy services by public-sector organisations. The purpose of this study was to appraise the performance of public-sector projects in which consultancy services have been outsourced or insourced. These are the gaps which this study was undertaken to fill.

A grounded theory methodology (GTM) research design was adopted based on the nature of evidence sought and gathered from a Provincial Department of Public Works and Infrastructure (PDPWI) in South Africa. Data was obtained from a mixture of semi-structured interviews and project-specific documents spanning a five-year period and was analysed according to the procedures associated with GTM. Accordingly, open coding, axial coding and pattern matching were carried out at several intervals to develop categories and themes.

The findings of the study showed the absence of a structured approach within the PDPWI for facilitating decisions pertaining to outsourcing or insourcing consultancy services within construction projects. Furthermore, the study established that both approaches yielded similar results across all performance facets of cost, time and quality. In addition, a detailed insight into the steps required for the successful application of GTM in built environment research has been provided in the study.

Limited studies have been undertaken to compare the impact of either outsourced or insourced services on the organisational and project performance. This was the gap to which the study reported in this paper was undertaken to contribute.

This study aims to analyze the effect of religiosity (RE), halal knowledge (HK) and halal certification (HC), attitudes, subjective norms and vaccine quality on the Muslim community’s intention to use halal vaccines in Indonesia.

This study involved 725 Muslim respondents in 32 Indonesian provinces. The model used was based on the theory of reasoned action development with the partial least squares structural equation modeling as the data processing tool.

The study discovered that RE, HK and HC did not affect the intention of Muslims to use halal vaccines. In addition, the MUI (Majelis Ulama Indonesia – Indonesia Council of Ulama) fatwa permitting the use of the AstraZeneca vaccine despite the haram ingredients was considered an excuse for Muslims to administer non-halal vaccines. However, several parties disagreed on the fatwa because the emergency legal standing for its permissibility did not apply to all regions. The reason was that each had different rates of confirmed cases, ranging from high-risk areas to those with zero confirmed Covid-19 cases.

This study examines the Muslim community’s intention toward using halal vaccines in several regions in Indonesia. In addition, this study conducted in-depth interviews as samples in several regions. This study also conducted interviews to determine the public’s views on government obligation about the Covid-19 vaccine. Finally, this study proposes a vaccine to avoid the possibility of controversy over the use of non-halal vaccines.

The research examines how behavioral intentions, as a higher-order construct, indirectly affect financial inclusion through service trust, usage behavior and financial literacy in mobile money adoption.

Following the positivist research philosophy, a cross-sectional study design was used to collect data through questionnaires comprised of scales adapted from prior studies. With a usable sample size of 340 respondents, this study employs partial least squares structural equation modeling to assess the model.

The study revealed the significant indirect role of behavioral intention on financial inclusion through use behavior, behavioral intentions on use behavior through service trust, and use behavior on financial inclusion through financial literacy. The role of behavioral intentions on financial inclusion through serial mediation of service trust, use behavior and financial literacy was also found to be significant.

This study's novelty resides in examining the indirect relationship between behavioral intentions and financial inclusion, specifically via the serial mediation of service trust, use behavior and financial literacy.

This paper aims to get an overview and determine the effect of the level of application of Islamic wealth management (IWM) and the level of business continuity of Muslim owners in influencing the level of household prosperity of Muslim micro, small and medium enterprise (MSME) owners during the Covid-19 pandemic.

The method of hypothesis testing is carried out through a quantitative approach. The type of analysis tool used is partial least square-structural equation modeling. The sample used is 212 Muslim MSME owners in Indonesia.

The results showed that the level of application of IWM, the level of business sustainability and the level of household prosperity of Muslim MSME owners were in the high category. All variables in this study showed positive and significant results.

The research conducted is still limited to households that act as MSME actors, so the respondents who are in it are still not diverse. Also, limited research tools and pandemic conditions led to filling out questionnaires based on respondents’ subjective views and difficulty asking questions when questions were not understood.

This research provides new insights focusing on the relationship between the variable level of application of IWM in influencing the welfare level of Muslim households who have MSMEs, where there is a role for the level of business sustainability as a mediator variable.

This study aims to see the variables of customer satisfaction level, attractiveness of alternatives, subjective norms and level of religiosity of conventional bank customers in West Java and their effect on switching intentions.

A causality description technique with a quantitative approach is used in this research. The analytical technique used is partial least square-structural equation modeling with a sample of 320 respondents from conventional bank customers in West Java.

The results revealed that the level of customer satisfaction and subjective norms were in the medium category, whereas the level of alternative attractiveness, religiosity and switching intentions was in high level. The level of customer satisfaction harms switching intentions, whereas the level of alternative attractiveness and religiosity variables have a positive effect on switching intentions. In contrast, the subjective norm variable does not affect switching intentions. Therefore, customer satisfaction, the attractiveness of alternatives and religiosity are essential points to cause someone to have the intention to switch.

For stakeholders, especially the government or the Islamic banking industry, to improve the climate of the Islamic finance industry in Indonesia, in particular, to increase knowledge and insight from the public regarding the intention to switch conventional bank customers to Islamic banks.

The use of the religiosity variable as an independent variable on switching intentions is still rarely done. Hence, the authors combine this variable with customer satisfaction, alternative attractiveness and subjective norms. The update in this study also places conventional bank customers included in the millennial generation and generation Z categories who live in the province of West Java as research subjects.

This study aims to investigate how fear of missing out (FOMO) mediates the relationship between cryptocurrency adoption intention and investment behavior among young Indians, using the extended unified theory of acceptance and use of technology.

The data were collected by using survey items on cryptocurrency adoption intention, investment behavior and FOMO derived from existing literature on information systems and cryptocurrencies. A total of 384 Indian participants completed an online questionnaire. The collected data was analyzed using PLS-SEM.

The findings indicate that facilitating conditions, social influence, effort expectancy and price value play important roles in cryptocurrency adoption. All hypothesized paths were significant, except for perceived risk. Furthermore, the study highlights that FOMO acts as a mediator between adoption intention and investment behavior.

This study makes a valuable addition to the literature by empirically exploring the influence of FOMO on the adoption of cryptocurrencies for investment purposes. The results provide valuable insights to crypto developers and exchanges regarding the diffusion of adoption in emerging markets. In addition, policymakers can gain meaningful insights into the influence of government regulations and FOMO on impulsive cryptocurrency behavior.

This study aims to evaluate the impact of sustainable strategic planning and management (SSPM) on sustainable performance (ecological, social and economic) among micro, small and medium enterprises (MSME) in the culinary sector in Southeast Asia (SEA).

This study used a quantitative approach surveying 300 halal-certified MSMS culinary businesses in the SEA region. Data were gathered using an online survey platform and analyzed using the partial least squares structural equation modeling technique.

Green management (GRM), digital transformation management (DTM) and Halal Business Management (HBM) exert a significant influence on SSPM. Furthermore, SSPM positively influences the sampled halal culinary MSMEs’ ecological, social and economic performances in SEA. The study also reveals that GRM, DTM and HBM positively influence Islamic ethics compliance and good governance.

This study sheds light on the often-ignored MSME business in the halal culinary sector in SEA. Examining sustainable and strategic planning synergy strengthens the development of a comprehensive framework for SSPM and could encourage more MSMEs to practice sustainable business operations. Moreover, the research also underlines the urgent need to harmonize halal standards in the SEA region. The approach would intensify multilateral support for economic growth and halal trade between SEA countries and beyond.

This study addresses the research gap in the strategic and sustainable management of halal culinary MSMEs within the developing and vast SEA economic region. This research is among the few, if not the first, that combines the GRM, DTM and HBM influence on SSPM and examines the impact on sustainable, ethical and good governance performances. The insights derived from this study contribute to formulating robust, sustainable policies, fostering avenues for sustainable initiatives and enhancing regional and global cooperation for a sustainable future.

The aim of this study is to examine the behavioral intention (BI) to adopt the Coinbase Wallet by Spanish users.

A survey was administered to individuals residing in Spain between March and April 2021. There were 301 questionnaires analyzed. This research applies a new predictive model based on technology acceptance model (TAM) 2, the unified theory of acceptance and use of technology (UTAUT) model, the theory of perceived risk and the commitment trust theory. A mixed partial least squares structural equation modeling (PLS-SEM)/fuzzy-set qualitative comparative analysis (fsQCA) methodology was employed for the modeling and data analysis.

The results showed that all the variables proposed have a direct and positive influence on the intention to use a Coinbase Wallet. The findings present clear directions for traders, investors and academics focused on improving their understanding of the characteristics of these markets.

First, this study addresses important concerns relating to the adoption of crypto-wallets during the global pandemic. Second, this research contributes to the existing literature by adding electronic word of mouth (e-WOM), trust, web quality and perceived risk as new drivers of the intention to use the Coinbase Wallet, providing unique and innovative insights. Finally, the study offers a solid methodological contribution by integrating linear (PLS) and nonlinear (fsQCA) techniques, showing that both methodologies provide a better understanding of the problem and a more detailed awareness of the patterns of antecedent factors.

There are many areas of research that are untapped in Islamic banking, and human capital is one of them. This paper aims to systematical review the relevant literature on human capital and Islamic banking.

The review process involved a structured search using well-established academic databases, Scopus and Web of Science, resulting in the selection of relevant articles. The paper has been divided into three major themes, besides other discussions on the literature, including methods of measuring human capital, determinants of human capital and human capital and performance of Islamic banks.

A few pioneering studies have explicitly examined human capital in the Islamic banking domain, while others have encompassed it under the broader umbrella of intellectual capital. The most common method of measuring human capital is accounting based, while few have adopted disclosure and survey methods as well. There are few studies that explored the determinants of human capital having focus on corporate governance, while many of the studies have explored the nexus of human capital and financial performance.

This review strongly highlights the need for more focused research on human capital within the Islamic banking sector. As Islamic banking necessitates unique human capital characteristics, it is essential to delve deeper into this aspect. Furthermore, there is a call to expand the human capital index by incorporating comprehensive aspects relevant to Islamic banking. An important area that requires further exploration is the role of Shariah governance in shaping human capital development within Islamic finance, understanding the reasons behind the observed negative correlation.

Despite its significance, the relationship between human capital and Islamic banking has received limited attention. This review paper not only addresses this gap but also lays the groundwork for future studies in this important and emerging field.

In mobile banking (m-banking), understanding the factors contributing to customer satisfaction is crucial for bank managers to design effective strategies for enhancing the uptake of mobile banking services. This study assesses the relationships between quality, technology acceptance and credibility factors and behavioural outcomes (actual use, continuance intention and loyalty) and satisfaction with m-banking. It further investigates the moderating influence of economy type, innovation level, connectivity level and sample size on all these relationships.

The study employs a meta-analysis technique and reviews 54 published studies to investigate the antecedents and consequences of satisfaction with m-banking.

The study finds a significant relationship between satisfaction with m-banking and quality, technology acceptance and credibility factors and behavioural outcomes. It concludes that the moderating effect of economy type, innovation level, connectivity level and sample size partially moderate the majority of the hypothesized relationships.

Drawing on a comprehensive literature review, this study presents a novel framework elucidating the antecedents and behavioural outcomes of satisfaction with mobile banking. It contributes to the literature by exploring the moderating effects of sample size and country context on the relationships between these factors, presenting important implications for future mobile banking research.

This study has practical implications for m-banking service providers, offering insights into the factors that drive user satisfaction with mobile banking and highlighting the need for tailored strategies in different country contexts.

This study examines the effects of factors leading to satisfaction and the subsequent outcomes within the context of m-banking. The findings offer fresh perspectives that can be valuable for managers and policymakers, enabling them to enhance customer satisfaction in the realm of m-banking.
