Transference-based trust (TBT) via referral sources is a cognitive process where trust in third-party information about an individual transfers to trust in the individual. TBT via referral sources can have significant effects on early trust development in a virtual team (VT). This study aims to examine the potential influence of Hofstede’s (1980) cultural variables and two proposed combinations of these cultural variables on early trust development in VT, including the effects of referral source.

This study adopted multigroup analysis partial least squares structural modeling to examine potential cultural differences in the responses of 357 university students from 51 different countries to understand early trust development in VT.

TBT via referral sources as in interpersonal construct has a positive, direct impact on early trust development. TBT mediated the individual and organizational model constructs. There were significant differences in the high/low values of 3 of the 56 tested cultural dimensions.

Reaffirmed the validity of cognitive-based trust models in understanding early trust development in VTs TBT as an interpersonal construct and has a significant influence on early trust development in VTs. TBT via referral sources mediated the individual and organizational constructs of the model. There were significant differences in the high/low measures of three cultural dimensions (i.e. IV, M and the combination of IV-M-LT) in the relationship of early trusting beliefs to early trusting intensions.

To positively influence interpersonal and organizational aspects of trust development, managers should ensure that the early phases of VTs, before actual implementation begins, are well organized. Managers could make VT members fully aware of how referral sources can influence early trust development. Managers could encourage individuals to have open access to relevant social media accounts for other VT members and encourage individuals to research referral sources on other VTs members. The implication for managers of culturally diverse VT is that the development of early trust is largely by individual choice, rather than differences in national culture.

People need to maintain and actively manage their online presence, ensuring that online information about them is accurate and updated. Referral sources could help VT members learn about one another, which might in turn help foster early trust in their online teams.

Although some studies have found significant cultural differences in early trust development, other studies, including a meta-analysis of 43 studies, found no significant cultural differences in early trust development. This study confirmed the results of the meta-analysis.

This paper aims to apply several data mining techniques for predicting the daily precision improvement of Jakarta Islamic Index (JKII) prices based on big data of symmetric volatility in Indonesia’s Islamic stock market.

This research uses big data mining techniques to predict daily precision improvement of JKII prices by applying the AdaBoost, K-nearest neighbor, random forest and artificial neural networks. This research uses big data with symmetric volatility as inputs in the predicting model, whereas the closing prices of JKII were used as the target outputs of daily precision improvement. For choosing the optimal prediction performance according to the criteria of the lowest prediction errors, this research uses four metrics of mean absolute error, mean squared error, root mean squared error and R-squared.

The experimental results determine that the optimal technique for predicting the daily precision improvement of the JKII prices in Indonesia’s Islamic stock market is the AdaBoost technique, which generates the optimal predicting performance with the lowest prediction errors, and provides the optimum knowledge from the big data of symmetric volatility in Indonesia’s Islamic stock market. In addition, the random forest technique is also considered another robust technique in predicting the daily precision improvement of the JKII prices as it delivers closer values to the optimal performance of the AdaBoost technique.

This research is filling the literature gap of the absence of using big data mining techniques in the prediction process of Islamic stock markets by delivering new operational techniques for predicting the daily stock precision improvement. Also, it helps investors to manage the optimal portfolios and to decrease the risk of trading in global Islamic stock markets based on using big data mining of symmetric volatility.

This research is a pioneer in using big data mining of symmetric volatility in the prediction of an Islamic stock market index.

Previous research has managed to clearly define lean technical competencies. However, the behavioral competencies remain underestimated, and the roles of lean experts are not clearly stated: are they teachers, facilitators or technical experts? The present paper investigates lean behavioral competencies and their relationship to lean experts' roles.

This article serves as an exploratory study built on interviews, observations and focus groups conducted during a three-year longitudinal study accompanied by a three-year follow-up. The case takes place in an international automotive company in partnership with Toyota in which lean adoption was part of a consistent strategy over a period of 20 years.

The study clarifies lean behavioral competencies related to organizational efficiency (nominal management, improvement management and respect for people) and relational efficiency (problem resolution, competencies development and systemic interactions). The study helped create a typology of lean experts' roles related to the maturity level of the environment in which they intervened. Moreover, Lean experts' roles in congruence with the environment seem to positively influence the creation of emerging human relationships that are beneficial to process improvement and competencies development.

This paper is the first to clarify behavioral competencies with respect to lean experts' roles and to study the temporality of the introduction of lean practices. The findings recommend that researchers better acknowledge the influence of lean behavioral competencies during lean adoption and their relationship to contextual factors and organizational performance. A practical methodology is proposed to measure the necessary behavioral adjustments of lean experts or employees.

This paper aims to introduce International Digital Collaborative Autoethnographical Psychobiography (IDCAP).

This paper describes how IDCAP was developed to answer research questions about what it takes and what it means to recover from mental illness. During its development, IDCAP combined the diverse and intersectional experiences, knowledge and interests of an Anglo-Swedish research team with what could be found in different publications concerning the experiences and the mental illnesses of the musicians Syd Barrett, Peter Green and Brian Wilson.

IDCAP combines features of autoethnography and psychobiography to offer a novel qualitative research method.

Whilst IDCAP was created to focus on recovery from mental illness and musicians, it can be applied to other areas of research. It shares the same limitations as autoethnography and psychobiography, although some of the features of IDCAP may go some way to mitigate against these.

IDCAP is a novel research method that is offered to other researchers to develop and enhance further through application.

IDCAP is a collaborative research method that encourages the involvement of a wide range of researchers from different countries and cultures. It can be used to give voice to marginalised groups and to counter discrimination and prejudice. Recovery from mental illness is a topic of great personal and social value.

IDCAP is a novel research method that, to the best of the authors’ knowledge, has not been explicitly used before.

This paper aims to provide an overview of the application of blockchain to agri-food supply chains, including key issues and trends. It examines the state of the art and conceptual structure of the field and proposes an agenda to guide future research.

This article performs a bibliometric analysis using VOSviewer software on a sample of 205 articles from the WoS database to identify research trend topics.

The number of publications in this area has increased since 2020, which shows a growing research interest. The research hotspots are related to the integration of blockchain technology in the agri-food supply chain for traceability, coordination between all actors involved, transparency of operations and improvement of food safety. Furthermore, this is linked to sustainability and the achievement of the sustainable development gtoals (SDGs), while addressing key challenges in the implementation of blockchain-based technologies in the agri-food supply chain.

The application of blockchain in the agri-food supply chain may consider four key aspects. Firstly, the implementation of blockchain can improve the traceability of food products. Secondly, this technology supports sustainability issues and could avoid disruptions in the agri-food supply chain. Third, blockchain improves food quality and safety control throughout the supply chain. Fourthly, the findings show that regulation is needed to improve trust between stakeholders.

The paper provides a comprehensive overview of the blockchain phenomenon in the agri-food supply chain by optimising the search criteria. Moreover, it serves to bridge to future research by identifying gaps in the field.

This paper aims to study the effect of concentric hot circular cylinder inside egg-cavity porous-copper nanofluid on natural convection phenomena.

The finite element method–based Galerkin approach is applied to solve numerically the set of governing equations with appropriate boundary conditions.

The effects of different range parameters, such as Darcy number (10–3 = Da = 10–1), Rayleigh number (103 = Ra = 106), nanoparticle volume fraction (0 = ϑ = 0.06) and eccentricity (−0.3 = e = 0.1) on the fluid flow represent by stream function and heat transfer represent by temperature distribution, local and average Nusselt numbers.

A comparison between oval shape and concentric circular concentric cylinder was investigated.

In the current numerical study, heat transfer by natural convection was identified inside the new design of egg-shaped cavity as a result of the presence of a circular inside it supported by a porous medium filled with a nanofluid. After reviewing previous studies and considering the importance of heat transfer by free convection inside tubes for many applications, to the best of the authors’ knowledge, the current work is the first study that deals with a study and comparison between the common shape (concentric circular tubes) and the new shape (egg-shaped cavity).

This study focused on exploring the performance factors (PFs) that impact Infrastructure Sanitation Projects (ISSPs) in the construction sector. The aim was twofold: firstly, to identify these crucial PFs and secondly, to develop a robust performance model capable of effectively measuring and assessing the intricate interdependencies and correlations within ISSPs. By achieving these objectives, the study aimed to provide valuable insights into and tools for enhancing the efficiency and effectiveness of sanitation projects in the construction industry.

To achieve the study's aim, the methodology for identifying the PFs for ISSPs involved several steps: extensive literature review, interviews with Egyptian industry experts, a questionnaire survey targeting industry practitioners and an analysis using the Relative Importance Index (RII), Pareto principle and analytic network process (ANP). The RII ranked factor importance,  and Pareto identified the top 20% for ANP, which determined connections and interdependencies among these factors.

The literature review identified 36 PFs, and an additional 13 were uncovered during interviews. The highest-ranked PF is PF5, while PF19 is the lowest-ranked. Pareto principle selected 11 PFs, representing the top 20% of factors. The ANP model produced an application for measuring ISSP effectiveness, validated through two case studies. Application results were 92.25% and 91.48%, compared to actual results of 95.77% and 97.37%, indicating its effectiveness and accuracy, respectively.

This study addresses a significant knowledge gap by identifying the critical PFs that influence ISSPs within the construction industry. Subsequently, it constructs a novel performance model, resulting in the development of a practical computer application aimed at measuring and evaluating the performance of these projects.

This paper aims to investigate how purchasing organizations implement supplier diversity (SD) initiatives over time.

A multiple case study approach was conducted. Data were collected through in-depth interviews with participants from purchasing organizations, intermediary organizations and diverse suppliers.

The research suggests that the SD journey encompasses three different, but interrelated stages before full implementation is achieved: structuring, operation and adaptation. The findings also provide evidence that SD implementation in Brazil is highly influenced by the lack of a consistent knowledge base and the lack of legitimized intermediary organizations.

Using a temporal approach to understand how different practices suggested by the literature have been managed by practitioners over time, this study contributes to the understanding of the path to effective SD implementation and how intra- and interorganizational context influences this journey.

By identifying which practices should be adopted during different phases of SD implementation and proposing ways to overcome some of the inherent challenges, managers can better plan and allocate resources for the adoption of a successful SD initiative.

This research demonstrates how organizations can promote diversity and reduce social and economic inequalities by buying from diverse suppliers.

Using a temporal approach, the research empirically investigates how different purchasing organizations have implemented and managed the known practices and dealt with the challenges faced when trying to adopt SD.

This study explores practitioners’ perspectives on the perceived gap between university and practice beyond the hard and soft skill paradigm. Utilising Tomlinson’s graduate capital model of employability (2017), we explored human, social, cultural, and psychological capitals to enrich the understanding of this issue and employability. It provided a new perspective, useful for implementing curriculum renewal.

This study utilised a two-stage mixed methods design. Using Tomlinson’s (2017) Graduate capital model as a framework, the first stage involved distributing an online survey to qualified architects in hiring positions practising in Australia. This served as the foundation for generating qualitative and quantitative data. The second stage involved a two-hour practitioner workshop where the survey results were discussed and expanded upon.

Our results found that the practitioner’s perspective on the perceived skills gap is more complex than the hard/soft skill paradigm commonly discussed. Practitioners expressed a need for students/graduates to possess identity and cultural capital to contextualise industry norms and expectations. This knowledge lets students know where and how hard/soft skills are used. Our results also suggest practitioners are concerned with the prevailing individualistic approach to the higher education system and traditional architectural teaching methods, instead suggesting a more industry-aligned collaborative disposition.

By expanding the employability discourse beyond hard/soft skills, the results of this research provide an opportunity for architectural curriculum renewal in line with industry expectations.

This project aims to examine how entrepreneurial orientation and succession planning among Palestinian family businesses positively affects their associated growth potential, considering the mediating role of innovation and the moderation effect of geographic location. Leveraging ethnic entrepreneurship theory, the authors compare these types of enterprises in the USA with their counterparts in Palestine.

This cross-sectional quantitative research analyzes data collected from October through December 2022. 180 Palestinian family-owned firms completed a survey; 90 companies were located in Palestine, while the other 90 were in the USA. Structural equation modeling analysis was conducted using Smart-PLS4. The interrelations of the conceptual framework were examined via path analysis and bootstrapping techniques.

The authors found a statistically significant positive effect of entrepreneurial orientation on Palestinian family business growth; the authors’ results concurrently indicated succession planning did not affect growth within the authors’ selected population. The authors also discovered innovation mediates the relationship between orientation and growth, and business location appears to moderate this relationship. The authors’ research indicates geography appears to favor Palestinian family-owned companies in the USA, where the authors found opportunity-driven immigrant entrepreneurs benefit from the structured business systems in a highly-developed country.

Given the current situation in Palestine, it is essential to understand the potential contribution that Palestinian family-owned businesses globally can make to reconstruct the country’s local economy. The next few years will be critical in figuring out how innovative thinking can boost the region’s recovery and increase Palestinian-based family companies’ ability to engage in sustainable entrepreneurship with reinvestment support from its diaspora. Therefore, it is important to have research that identifies factors that could improve these businesses’ continued performance and growth potential. This study also aids in further understanding the defining characteristics of Palestinian-owned family firms, enhancing general theories related to entrepreneurship among ethnic and diasporic groups.
