This study aims to examine the international market selection process of entrepreneurs operating internationally.

Four small and medium-sized comparative and rich-information case studies were purposefully selected from among Australian and Arabian firms. Data were collected via in-depth personal interviews, follow-up interviews and questionnaire instrument.

The results revealed that entrepreneurs used a four-stage systematic decision-making process to attain profitable foreign market choices. The decision process was influenced by cognitive boundaries as entrepreneurs relied on the availability experiential, anchoring and adjustment heuristic.

The research’s findings and the proposed decision model will, significantly, assist entrepreneurs, willing to expand internationally, in enhancing their decision-making to attain profitable foreign market choices. Further, it provides benefits to foreign investment policymakers in host countries by assisting them to attract more inward foreign direct investments, and, accordingly, enhance the economic and social development movement in their countries.

This study provides a significant theoretical contribution to the literature on the internationalization process of entrepreneurs and small- and medium-sized enterprises through developing a decision model for selecting and entering foreign markets by entrepreneurs in a cross-country context. Further, the study provides significant methodological contributions with regard to the effectiveness of the qualitative case study method in capturing elements of the foreign market selection process.

This study examined the differences among 76 American project managers and 36 of their Arab counterparts with regard to their perceptions of factors contributing to effective project management. After reviewing the relevant literature, a conceptual framework was derived. Seven research hypotheses were formulated and tested. The results of this study tended to underscore the significance of cultural differences among these two groups of project managers.

The purpose of the paper is twofold. Firstly, this study aims to investigate the factors influencing stakeholders’ intention to invest in Shariah-compliant social impact bonds (SC SIBs) in Malaysia. Secondly, this study compares the differences in the perception of different stakeholders on the importance of the factors.

Using the extended theory of planned behaviour, the study undertakes a questionnaire survey on licensed capital market investors and individuals involved in the development of the financial market (developers). A total of 260 complete and valid responses were obtained from the survey. Multiple regression and Mann–Whitney tests were carried out to achieve the two objectives, respectively.

The results reveal that attitude (β = 0.447, p < 0.01), subjective norm (SN) (β = 0.255, p < 0.01) and moral norm (MN) (β = 0.163, p < 0.01) are significantly positive predictors of intention to invest in SC SIBs. In terms of the differences in the perceptions of the two parties, the results show that the factors have more effect towards developers than investors.

The empirical evidence from this study on the factors that influence stakeholders’ participation in SC SIBs is useful to the policymakers and interested parties in taking the next steps to develop, implement and promote SC SIBs to stakeholders in Malaysia. Fund managers can use the study’s insights to promote positive attitudes, SNs and MNs towards SC SIBs, especially targeting developers who are more influenced by these factors. More importantly, the results indicate a need for different strategies to influence the stakeholder investment behaviour of SC SIB in Malaysia to ensure that it is sustainable and viable in the long run.

This study aims to explore the determinants that impact state Islamic University/Perguruan Tinggi Keagamaan Islam Negeri students’ intention to adopt online cash waqfs. In doing so, this study integrates knowledge of cash waqf and trust variables within the theory of planned behavior (TPB), allowing an examination of the mediating role of TPB variables and trust within the relationship between knowledge of cash waqf and intention for online cash waqf behavior.

To carry out an empirical analysis, the authors developed a well-structured questionnaire and distributed it to a group of students currently enrolled in PTKIN, obtaining 443 usable responses. The partial least squares-structural equation modeling (PLS-SEM) technique was used for the dual purposes of data analysis and hypothesis testing.

This study demonstrates that factors such as attitude, subjective norms, perceived behavioral control, trust and knowledge of cash waqf have a significant and favorable influence on the intention to donate through e-cash waqf. Knowledge of cash waqf impacts attitudes, subjective norms, perceived behavioral control and trust. The final analysis shows that attitude, subjective norms, perceived behavioral control and trust partially mediate the relationship between knowledge and intention in the online cash waqf context.

The aforementioned elucidates the paramount importance of trust in shaping individuals’ tendencies to engage in cash waqfs. The insights mentioned have the potential to be used by cash waqf establishments to promote transparency and accountability, ultimately bolstering the confidence of potential donors.

The concepts of waqf and the use of online cash waqf as a means of donation in developing countries are relatively new. In this study, the intention of students to adopt online cash waqf was predicted for the first time by considering their knowledge of cash waqf and their trust in online cash waqf transactions.

The objectives of this paper are two-fold: first, to empirically compare and contrast the salient features of three financial instruments (FIs), namely sustainable and responsible investment (SRI) ṣukūk, social impact bonds (SIBs) and conventional bonds (CBs) and second, to examine the differences between the perceptions of the investors and the developers on the features of the three FIs.

Using a questionnaire survey, 251 completed and useable responses were received, representing a 42.54% response rate. In examining the differences and similarities in the characteristics of the three FIs, the inferential statistical of frequency and percentage were used. Wilcoxon and Mann–Whitney tests were conducted to investigate the differences in the salient features of the three FIs and the differences between the investors and developers' perceptions on the salient features of SRI ṣukūk, SIBs and CBs, respectively.

The results reveal that stakeholders view SRI ṣukūk, SIBs and CBs to be statistically significantly different from each other. This shows that stakeholders do not view SRI ṣukūk as “old wine in a new Sharīʿah-compliant bottle” but instead considered different from SIBs and CBs. Furthermore, stakeholders also differentiate between SIBs and CBs.

The paper provides empirical evidence that Islamic finance (IF) instrument, represented by SRI ṣukūk, is viewed as different instruments to conventional tools, represented by SIBs and CBs. First, it debunks the notion that IF is viewed as similar to its conventional counterpart. Second, SIBs are seen as different from CBs, illustrating the distinct categorisation of impact investing instruments. As such, third, the development of SRI ṣukūk and SIBs can provide diversification to portfolios as it is a unique instrument in the social finance and financial market.

This study looks at drivers of internationalisation and the important location decision factors contributed to the selection of a beneficial country for international expansion. One in‐depth and information‐rich case study of the Arabian premium international professional service firms was purposively undertaken. The results show that both firm and location‐specific factors, firm’s competitive advantage, company’s management attitudes and profit growth were the main drivers of internationalisation. Further, the study reveals that the pre‐development of country qualitative and quantitative location factors was elemental to attain profitable foreign country choice. Accordingly, these findings have significant theoretical and practical implications to the internationalisation and foreign market entry of professional service firms.

This study aims to develop a holistic method that integrates finite element modeling, machine learning, and experimental validation to propose processing windows for optimizing the laser powder bed fusion (LPBF) process specific to the Al-357 alloy.

Validation of a 3D heat transfer simulation model was conducted to forecast melt pool dimensions, involving variations in laser power, laser scanning speed, powder bed thickness (PBT) and powder bed pre-heating (PHB). Using the validated model, a data set was compiled to establish a back-propagation-based machine learning capable of predicting melt pool dimensional ratios indicative of printing defects.

The study revealed that, apart from process parameters, PBT and PHB significantly influenced defect formation. Elevated PHBs were identified as contributors to increased lack of fusion and keyhole defects. Optimal combinations were pinpointed, such as 30.0 µm PBT with 90.0 and 120.0 °C PHBs and 50.0 µm PBT with 120.0 °C PHB.

The integrated process mapping approach showcased the potential to expedite the qualification of LPBF parameters for Al-357 alloy by minimizing the need for iterative physical testing.

This study aims to explore the effect of mental health in terms of depression, anxiety, stress, fear of COVID-19 and quality of life (QoL) on the reluctance to be vaccinated in a population of Palestinian adults living in occupied Palestinian territories and Israel.

The authors recruited 1,122 Palestinian adults who consented to participate in the study; 722 were females, and the mean age of the sample was 40.83 (SD 8.8). Depression, anxiety, and stress scale (DASS), World Health Organization QoL-BREF, FCov-19 and reluctance to the vaccine scale were administered; hierarchical regression analysis was applied to test vaccine reluctance as a dependent variable, and mental health, fear of COVID-19 and QoL as independent variables. This study hypothesized influence of such variables on the vaccine choice with differences due to the participants’ geographical locations.

Findings showed an effect of mental health, particularly depression, QoL and fear of COVID on vaccine reluctance, with depression and fear of COVID in the West Bank and Gaza, while in Israel, QoL played a role in vaccination choices.

The future needs to be comprehended more thoroughly to discover mutations and fluctuations over time in vaccine hesitancy and the increasing role of psychological distress, diminished QoL and fear of Covid-19. Online recruitment might not have allowed the study to include the most disadvantaged strips of the Palestinian population.

Human rights perspectives must be considered in public health and public mental health policies to ensure the QoL and well-being for the Palestinian population during and following the pandemic.

The crumbling of the Palestinian health-care system exacerbated the sense of dread among the population and made them less likely to vaccinate. The pandemic-like spread of Covid-19 prompts a plea for the global community to actively advocate for the urgent re-establishment of equity, autonomy and durability of the medical infrastructure in the occupied territories and equal entitlements for the Palestinians in Israel.

The results demonstrated the importance for public mental health to consider the multiple levels implied in the vaccine refusal in Palestine and Israel among the Palestinian population.

For metal additive manufacturing, metallic powders are usually produced by vacuum induction gas atomization (VIGA) through the breakup of liquid metal into tiny droplets by gas jets. VIGA is considered a cost-effective technique to prepare feedstock. In VIGA, the quality and the morphology of the produced particles are mainly controlled by the gas pressure used during powder production, keeping the setup configuration constant.

In VIGA process for metallic additive manufacturing feedstock preparation, the quality and morphology of the powder particles are mainly controlled by the gas pressure used during powder production.

In this study, Inconel-625 feedstock was produced using a supersonic nozzle in a close-coupled gas atomization apparatus. Powder size distribution (PSD) was studied by varying the gas pressure.

The nonmonotonic but deterministic relationships were observed between gas pressure and PSD. It was found that the maximum 15–45 µm percentage PSD, equivalent to 84%, was achieved at 29 bar Argon gas pressure, which is suitable for the LPBF process. Following on, the produced powder particles were used to print tensile test specimens via LPBF along XY- and ZX-orientations by using laser power = 475 W, laser scanning speed = 800 mm/s, powder layer thickness = 50 µm and hatch distance = 100 µm. The yield and tensile strengths were 9.45% and 13% higher than the ZX direction, while the samples printed in ZX direction resulted in 26.79% more elongation compared to XY-orientation.

This study aims to investigate the impact of financial and behavioural factors on investment decisions in the cryptocurrency market within the Gulf Cooperation Council (GCC).

The study uses the cross-sectional absolute deviation methodology developed by Chang et al. (2000) to determine the existence of herding behaviour during extreme conditions in the cryptocurrency market of four GCC countries: Bahrain, Saudi Arabia, Kuwait and UAE. In addition, a questionnaire survey was distributed to 322 investors from the GCC cryptocurrency markets to gather data on their investment decisions.

The study finds that the herding theory, prospect theory and heuristics theory account for 16.5% of the variance in investors' choices in the GCC cryptocurrency market. The regression analysis results show no multicollinearity problems, and a high F-statistic indicates the general model's acceptability in the results.

The study's findings suggest that behavioural and financial factors play a significant role in investors' choices in the GCC cryptocurrency market. The study's results can be used by investors to better understand the impact of these factors on their investment decisions and to develop more effective investment strategies. In addition, the study's findings can be used by policymakers to develop regulations that consider the impact of behavioural and financial factors on the GCC cryptocurrency market.

This study adds to the body of literature in two different ways. Initially, motivated by earlier research examining the impact of behaviour finance factors on investment decisions, the authors look at how the behaviour finance factors affect investment decisions of the GCC cryptocurrency market. To extend most of these studies, this study uses a regime-switching model that accounts for two different market states. Second, by considering the recent crisis and more recent periods involving more cryptocurrencies, the authors have contributed to several studies examining the impact of behavioural financial factors on investment decisions in cryptocurrency markets. In fact, very few studies have examined the impact of behavioural finance on cryptocurrency markets. Therefore, to the best of the authors’ knowledge, this study is the first of its kind to investigate how behavioural finance factors influence investment decisions in the GCC cryptocurrency market. This allows to better illuminate the factors driving herd behaviour in the GCC cryptocurrency market.
