This paper aims to present spot pattern welding (SPW) as a scanning strategy for laser-foil-printing (LFP) additive manufacturing (AM) in place of the previously used continuous pattern welding (CPW) (line-raster scanning). The SPW strategy involves generating a sequence of overlapping spot welds on the metal foil, allowing the laser to form dense and uniform weld beads. This in turn reduces thermal gradients, promotes material consolidation and helps mitigate process-related risks such as thermal cracking, porosity, keyholing and Marangoni effects.

304L stainless steel (SS) feedstock is used to fabricate test specimens using the LFP system. Imaging techniques are used to examine the melt pool dimensions and layer bonding. In addition, the parts are evaluated for residual stresses, mechanical strength and grain size.

Compared to CPW, SPW provides a more reliable heating/cooling relationship that is less dependent on part geometry. The overlapping spot welds distribute heat more evenly, minimizing the risk of elevated temperatures during the AM process. In addition, the resulting dense and uniform weld beads contribute to lower residual stresses in the printed part.

To the best of the authors’ knowledge, this is the first study to thoroughly investigate SPW as a scanning strategy using the LFP process. In general, SPW presents a promising strategy for securing embedded sensors into LFP parts while minimizing residual stresses.

The provision of online information through the use of digital platforms (websites and social networks) can be helpful for public sector organisations to promote transparency and accountability, thereby bringing it closer to citizens, more accessible and with higher added value for society. Whereas the call for government transparency is manifest and seems to be equal for all parts of government, this paper investigates whether small government entities are able to cope with this demand. In addition, the drivers of digital platforms are investigated in the context of Portuguese parishes.

The paper follows a quantitative research approach based on an original data set with more than 3,000 observations collected in two different time periods (2015 and 2020), which looks at the parishes’ use of website and Facebook.

Findings show that about half of Portuguese parishes, which are mostly small entities with on average fewer than 3,500 inhabitants, have an institutional website, whereas almost three out of four have Facebook. The empirical analyses reveal that a lack of organisational capacity of small entities can be an obstacle for the use of an institutional website and of Facebook. Furthermore, factors from the provider side (e.g. being part of a merger, participation in previous elections) and the user side (e.g. having access to broadband internet) are also found to have an influence on the adoption, use, and dropping of a digital platform.

The use of an original data set with more than 3,000 observations, and the research of the influence of size as a proxy of organisational capacity on the presence of parishes on the internet and Facebook, are innovative elements of this paper. In addition, this study adds to the knowledge about the influence of organisational, political, and socio-demographic characteristics on the use of digital platforms by small government entities.

People start to acknowledge, accept and adopt fintech applications due to its flexibilities, compatibility, ease to use, security and usefulness. A growing body of research reveals a positive perception of micro-enterprises towards fintech instruments. Looking at the potential of the fintech platforms and tools in Malaysia, the purpose of this study is to look at the readiness of micro-entrepreneurs towards using it as a medium in generating more income and profit for their business.

This study uses a quantitative approach with 200 questionnaires distributed to micro-entrepreneurs in Malaysia. IBM SPSS was used to perform a preliminary analysis of the data (descriptive analysis), then partial least squares-structural equation modelling SmartPLS is used to test the hypothesised relationships.

This study found perceived ease of use H1 (β = 0.523, p < 0.01) and trust H4 (β = 0.211, p < 0.10) play an important role in readiness to adopt fintech. Whereas, security H3 (β = 0.068) and perceived usefulness, H2 (β = 0.120) are insignificant (rejected).

This study provides evidence on the factors that contribute most towards the inclination to use fintech application among micro-entrepreneurs. In fact, tightening the policy regarding the security matter could enhance the readiness of micro-entrepreneurs to use fintech application.

This study investigates factors that influence the readiness of micro-entrepreneurs to adopt fintech application, which were not considered by previous studies.

The extensive use of mobile money (MM) has been widely recognized as a digital engine of socioeconomic development in sub-Saharan Africa (SSA). This paper aims to focus on the effects of MM use and stockouts on informal microenterprise performance and investigate whether MM use mitigates the relationship between stockouts and firm performance.

This study utilizes firm-level data from the latest World Bank Informal Sector Enterprise Surveys across six SSA countries. We employ instrumental variable-adjusted and propensity score-weighted regressions to investigate the buffering effect of MM use.

We find a significantly positive effect of MM use and a significantly negative impact of stockouts on informal microenterprise performance. Importantly, we establish that MM use attenuates the negative impact of stockouts on firm performance. We further document that the attenuating effect of MM use is more profound for firms using MM for transactions with supply chain partners, located in communities with high MM use rates, and operating in the retail industry.

Our research generates important managerial and policy implications. Future policies should capitalize on MM to foster an effective financial ecosystem in which informal microenterprises can survive and grow, thereby deepening their contributions to sustainable development.

Whereas the business benefits of MM among small, medium and large firms are well-documented, the role of MM use on informal microenterprise performance is less understood. This study fills the research gap in the literature by focusing on the influence of MM use on the relationships between informal microenterprise operations and performance.

This study uses a systematic review to explore the potential causes of previous findings related to e-government acceptance research. By identifying the most frequently used, best, promising or worst factors that affect the acceptance of e-government, this research presents a research agenda for e-government researchers.

Through conducting a systematic review following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) procedure, this research first selected 109 papers. Subsequently, this research analyzed the predictors and linkages of e-government acceptance by adopting a weight-analysis method proposed by Jeyaraj et al. (2006).

The results first revealed the five most frequently used predictors and five best predictors of e-government acceptance at a comprehensive level. Furthermore, this study summarized the best predictors affecting the acceptance of e-government from the perspectives of adopter types and e-government stages. The results also illustrated the promising and the worst predictors influencing e-government acceptance.

The contribution of this research is twofold. First, this study identified the linkages between e-government acceptance at the individual and organizational levels and between different e-government development stages. Second, this research provided a research direction that could offer useful insights for future e-government studies.

Despite the positive impact of professional learning communities (PLCs) in improving teaching practices, many teachers still struggle to effectively integrate information and communication technologies (ICTs) into their teaching and learning. Drawing from human capital theory and spillover effects, this paper examines how teachers PLCs can facilitate ICT integration.

Using a qualitative methodology, the researchers designed a phenomenological study. From semi-structured interviews, data were collected from 15 selected secondary school teachers from four selected secondary schools in Tanzania.

The study revealed that teachers use various strategies to enhance ICT integration in teaching practices, namely, community collaboration, practice-based approaches to ICT integration and the utilization of digital learning tools in instructional practices. Furthermore, the results showed several constraints on the ability of teachers’ PLCs to encourage ICT integration. These constraints were divided into three parts, i.e. major challenges at the macro, meso and micro levels.

The paper has the potential to inform policy and practice, particularly in the area of PLCs. Also, it helps to better understand the changing practices with ICTs through PLCs when there are insufficient resources for ICT integration.

To support teachers in using ICTs in their instructional practices, it is essential to build their capacities through PLCs to increase their confidence and competence in ICT integration.

The COVID-19 pandemic has had a devastating impact on all facets of education. This led to educational institutions deploying blended and online systems for teaching and learning. The purpose of this study was to assess the role of blended learning in promoting quality education during the COVID-19 pandemic.

The qualitative research design was deployed in this study and enabled the researcher to collect data via in-depth interviews. Twenty-five (25) tertiary institutions accredited by the Ghana Tertiary Education Commission (GTEC) were randomly selected to participate in this study. The registrars of the institutions were purposively selected and served as the participants for the study. Thematic content analysis was used to analyze the data collected via the interview. Ethical considerations were adhered to during the study.

The study established that COVID-19 had a devastating effect on tertiary institutions; multiple technological and open-sourced systems were deployed for teaching and learning; blended learning was adopted to augment the traditional face-to-face mode of teaching and learning due to its ease of use, usefulness and accessibility as it was used for quizzes and assignments, accessing lecture notes, among others. Despite these, the deployment of technological and blended systems was met with challenges that somehow affected effective teaching, learning.

The study was limited to 25 tertiary educational institutions in Ghana. It was again limited to the COVID-19 era.

This research aids in understanding the extent of the impact of COVID-19 on teaching and learning and how blended learning is currently deployed and used in tertiary institutions in Ghana. The findings are relevant to policymakers and management of educational institutions as it informs them of the right method and tools to deploy for teaching and learning during pandemics.

As educational institutions globally are dealing with the effect of the COVID-19 pandemic, it is prudent to look into how tertiary institutions in Ghana deploy blended learning to facilitate teaching and learning. Thus, this paper is original as it fills the relevant literature gap in terms of scope, setting, methodology and findings.

This study combines the TAM and UGT frameworks to investigate how Vietnamese students' views of ChatGPT and intrinsic needs affect their intentions to use it for education (via variables including perceived ease of use, perceived usefulness, novelty, information seeking and academic content creation). We will employ TAM theory (Davis, 1989) and UGT theory to elucidate university students' motivations for utilising ChatGPT in Vietnam. Simultaneously, we aim to address the limitation stemming from data uniformity. Our research will make a substantial contribution to the understanding of researchers regarding the use of ChatGPT and its varied consequences as it grows and develops.

This study was conducted at a private university in Vietnam with an estimated population of 15,000 students. One of Vietnam’s top private information technology institutions requires its students to use a variety of information and communication technologies (ICTs) on a regular basis to facilitate and enjoy their academic pursuits (Ngo, 2024; Nguyen). Students who are familiar with ChatGPT and have access to it for educational purposes are the ones that were chosen. This research is a quantitative study that utilises primary data through a survey method. Participants answered a questionnaire online through the Google Form platform sharing via social media platforms from October to December 2023. The questionnaire was divided into two sections: the first contained screening questions and demographic information and the second had five-point Likert-scale questions that measured the study’s components. Two screening questions are used to separate out the intended responders. (i.e. “I have heard the name ChatGPT” and “I know about ChatGPT”) were set to find whether the participants had any knowledge of ChatGPT. If participants were unaware of ChatGPT, their responses were not included in the study. A total of 283 responses were received. The participant’s demographic information is shown in Table 1. It is believed that a sample size of more than 200 provides adequate statistical power for data analysis in structural equation modelling. It is evident that the 283-sample size in this study is adequate to evaluate the research hypothesis and the fitting model. 42.9% of the 283 research samples were made up of men, while 57.1% were women. Business administration accounted for 40.1% of survey respondents, followed by information technology (25.2%) and English language (14.5%). The average ChatGPT usage time of respondents was 56 min in a single use. The study sample’s average age is 20–72 years old.

The present study contributes to the existing AI chatbot literature in the educational industry in several ways. First, this study addresses a gap in the literature by investigating the factors that influence students’ ITU ChatGPT for educational purposes in Vietnam. Using the extended model, we investigated factors influencing students’ intentions to use ChatGPT. It integrates three motive factors of the UGT (ACT, IS and N) with the core factors of TAM (PeoU and PU). The integrated framework’s findings indicate that in a Vietnamese educational setting, ChatGPT is a novel technology that should be considered in conjunction with PU and PEoU.

First, only Vietnamese students make up the research sample. To increase the relevance of the findings, it is advised that future research look at the study model in various geographic regions. Second, the present investigation’s constraints arise from the lack of clarity about the Chat GPT version utilised by the respondents, specifically whether it was the free or premium edition. Furthermore, the limited duration of the survey presents an obstacle to gathering thorough data. Due to their reliance on the particular features and functionalities of the Chat GPT version used, these restrictions may have an effect on the researcher’s objectivity. Furthermore, the limited survey time may curtail the coverage of the collected answers, particularly considering that our survey predominantly focuses on business administration students, thus limiting the diversity and richness of the gathered data. We recommend that future studies should conduct comparative research between different versions of GPT Chat, including free and paid variants that can provide valuable insights into potential differences in performance and results. Such analysis can provide a deeper understanding of the strengths and limitations of different GPT Chat versions. Third, because the study focused on behavioural intention, actual usage and post-usage behaviour may not be covered by the findings. To gain a deeper understanding of users' actual behaviour, we suggest doing research on their usage and post-usage behaviours.

The findings will assist service providers and legislators in determining critical variables and influencing students' incentives to use ChatGPT in educational settings that use constructivist teaching methods. As a result, the information will assist service providers in creating AI chatbots that are more user-friendly, visually appealing, efficient, safe and convenient for education. Governments, in conjunction with service providers, have the potential to significantly accelerate the adoption of AI-based chatbots by highlighting their ethical and sustainable use. The findings demonstrate that students' ITU towards ChatGPT is substantially impacted by PU and PEoU. It is recommended that service providers emphasize the advantages and ease of use of AI chatbots in order to draw new clients. Additionally, in order to promote ChatGPT or related technologies, marketers should concentrate on raising the technology’s perceived novelty value. This is because people are open to new technologies as long as they believe they are interesting and innovative.

ChatGPT is an advanced AI-powered chatbot that has the potential to advance and revolutionize the learning and teaching process. This study attempted to look at the elements that lead students to want to use ChatGPT from an academic standpoint by combining the UGT and TAM. For practitioners, academics and educators, the findings provide a solid knowledge of and encouragement for the sustainable use of such AI tools. Despite having important practical consequences, the study contains a number of limitations that indicate possible research gaps that should be filled by further investigation.

A mobile wallet (m-wallet) is a part of financial technology products and is still in the infant stage in Palestine. The technology acceptance model (TAM) formed the basis of the model development, which was extended in the study to include an analysis of how knowledge sharing (KOS), perceived value (PEV), perceived privacy awareness and control (PRI) and perceived security (SEC) influenced the primary TAM components of perceived ease of use (PEU), perceived usefulness (PRU) and intention to use m-wallets among Palestinian users.

This study used questionnaires as its primary data collection method. The questionnaires were distributed via online media, and the data collection period spanned from January 10, 2023, to February 21, 2023. The study received 360 responses from participants. Smart PLS and SPSS v.23 software were used to perform a method test on the collected questionnaire data.

The study’s findings demonstrate the factors influencing Palestinian users’ adoption of m-wallets by extending the Technology Acceptance Model (TAM) to include knowledge sharing, perceived value, privacy awareness and control and security, in addition to the main TAM elements, perceived ease of use (PEU) and perceived usefulness (PU), offering new insights into technology adoption in developing regions and addressing gaps in the literature.

This study has some limitations. First, it is limited because it looks at users’ intentions to use rather than their actual usage. The actual use of an m-wallet should be the topic of further research. Second, rather than focusing on Small and Medium Enterprises (SMEs), this study examined users’ intentions to use m-wallets. Thus, SMEs’ use of m-wallets may be studied in future research. Third, because the study users were from Palestine, the results may not be generalizable. Therefore, additional populations and cultures should be studied in future research. Fourth, the study used a convenience sample of 282 users. As a result, it is not easy to generalize to a sizable population. Future studies should use larger sample sizes or random samples. Finally, this study examined the direct relationship between independent and dependent variables. Future research may consider personal innovativeness and artificial intelligence as potential moderators.

User knowledge sharing can be an important factor driving user intention to use m-wallet. Users can raise awareness of m-wallets by sharing their knowledge and experiences with others about their uses, features and advantages. This is particularly useful in a country like Palestine, where m-wallets are not widely accepted or used. Therefore, m-wallets service providers should improve their services to motivate the users to share their knowledge with others to increase user intention to use. For instance, m-wallet service providers can provide user support programs that assist users in resolving issues, responding to inquiries and offering feedback on the service. Additionally, m-wallet service providers can enhance the user experience of their m-wallet by providing user-friendly interfaces, quick and dependable service and robust security features. By improving the user experience and providing users with a supportive and responsive environment, service providers can encourage users to share their positive experiences with others and increase user intention to use the m-wallet. User knowledge sharing can be an important factor driving user intention to use m-wallet.

Additionally, m-wallet service providers can enhance the user experience of their m-wallet by providing user-friendly interfaces, quick and dependable service and robust security features.

The widespread adoption of m-wallets is an important area of research, as it has significant theoretical implications for technology adoption. M-wallets provide an easy and secure way to pay without cash or physical cards. Therefore, identifying the factors affecting users’ intention to use m-wallets can help Palestinian m-wallet service providers to develop their marketing strategies. Extending the TAM to include four important factors (knowledge sharing, perceived value, perceived privacy awareness and control and perceived security) has improved our understanding of technology adoption models. The study empirically examines the intentions of Palestinian users to use m-wallets and how this novel technology is used in this area of the Arab world. The results empirically support that these factors strongly affect users’ intentions to use m-wallets. Thus, this study fills the knowledge gap about the factors influencing the use of m-wallets in Palestine and adds to the literature on the user intentions to use new technologies. Finally, this study is one of the first to examine the relationship between knowledge sharing, perceived value, perceived privacy awareness and control, perceived security and technology acceptance models in general and the extended TAM with these factors in a specific m-wallet context.

The preliminary empirical study investigates the factors affecting the use of m-wallets in Palestine by extending TAM with knowledge sharing, perceived value, perceived privacy awareness and control and perceived security as external variables to the model. The findings of this study help to fill a gap in the existing literature by identifying key variables that affect Palestinians’ intentions to use m-wallet. This study also contributes to the increase in knowledge in the area. To date, no studies have explored privacy in terms of awareness, control and knowledge sharing as essential factors that affect users’ intention to use m-wallets in Palestine.

Recognizing the importance of Robo-advisors in digital financial services, this paper aims to analyse the users’ perception and acceptability of artificial intelligence (AI) in digital investment solutions using an extended “Technology Acceptance Model” (TAM).

The model is tested using 454 online valid responses received from Indian Fintech users via direct path analysis, mediation and moderation.

The study’s findings show that trust, perceived usefulness and perceived risk all significantly impact users’ attitudes towards Robo-advisors. In contrast, ease of use and social influence did not impact users’ attitudes statistically. Furthermore, the results indicate that their attitudes and ease of use influence users’ intentions to adopt Robo-advisors. Moreover, the moderation effect of gender partly supports the overall model. Specifically, in the path between attitudes and their antecedents, gender plays a role in influencing the relationships among these variables. This aligns with preliminary research in the field, providing additional insight into how gender may moderate the factors influencing users’ attitudes and intentions regarding Robo-advisory services.

This research study also reveals that trust, perceived risk, ease of use and demographic factors influence the adoption of Robo-advisory services. It is functional, but its sample selection is not probabilistic and overly emphasizes gender. Future research should use probabilistic sampling, other demographic factors and experience and situational factors. Also, it is necessary to examine how convenient and satisfying it is to communicate with service providers. Filling these gaps will improve the knowledge of consumer behaviour in the context of Fintech adoption and develop the current research.

This study posits that perceived usefulness, trust, perceived risk and ease of use remain core determinants of adopting Robo-advisory services. So, to improve the level of trust of users, it is necessary to develop security measures, data clarity and quality and customer support. Enhancing ease of use by incorporating better interface gestures is always beneficial for increasing the number of users and their level of satisfaction. As identified in previous studies, practical solutions will be achieved by pursuing the increased use of technology while leveraging AI for personal services and minimizing perceived risks, which will strengthen more advanced security measures as well as sufficiently clear communication.

The paper aims to extend the TAM by incorporating measures of trust and social influence to identify the factors that drive the adoption of Robo-advisors. In doing so, the paper may contribute to developing a more comprehensive understanding of the factors that shape consumers’ attitudes and intentions towards these technologies. Moreover, the paper appears to examine the moderating effect of gender on attitude and its predictors, which could provide insights into how gender characteristics may impact the adoption of Robo-advisors.
