In recent years, the usage rate of electronic money (e-money) has grown rapidly in many countries around the world and is becoming widely accepted in developing nations due to evolving market conditions and buying patterns. This study explores the determinants of customers' behavioural intention (BI) and actual usage behaviour (UB) of e-money service in a transition economic setting. Additionally, since there has been limited research on moderating influences, this study introduces perceived risk (PR) as a moderator, underpinned by relevant technology acceptance and behavioural theories.

The proposed model and hypothesised variable relationships are tested using partial least squares-structural equation modelling (PLS-SEM) with survey data from 337 e-money service users in Indonesia.

The empirical results revealed that facilitating conditions (FCs), hedonic motivation (HM), price value (PV), habit (HT) and PR are important determinants of customers’ BI towards e-money and most of these variables also affect actual UB of e-money services. Performance expectancy (PE), effort expectancy (EE) and social influence (SI) emerged to be insignificant determinants. The study also uncovered that PR negatively moderates the links between EE, SI, HM, PV and BI towards e-money services. Likewise, PR has an adverse effect on the BI–actual UB relationship.

A large portion of the sample comprised young individuals with tertiary education. In essence, the sample represents the millennial generation and they are generally characterised as responsive, innovative and technology literate. Future studies could advance the present understanding by comparing different customer backgrounds and country.

The results shed light into the key factors that enhance e-money usage behaviours and have direct managerial implications with regard to brand strategy and market targeting. The findings imply that e-money service providers should take initiatives to retain users with effective and personalised marketing efforts, particularly via mobile media brand promotions.

While there has been considerable discussion on how PR may impact on initial preference and adoption of e-money, existing studies seem to fall short in conceptualising and empirically examining the moderating role of PR on the determinants and outcome of e-money BI.

With the emergence of coronavirus disease 2019 (COVID-19), the usage of e-money has been reinforced to reach the next level. Therefore, this study aims to examine the mediating role of perceived behavioral control (PBC) on the nexus of customers' innovativeness and continuance intention of electronic money (e-money). This study also explores the moderating roles of perceived risk (PR) and electronic security (e-security) in relationships.

The authors employed a structured questionnaire for data collection and the partial least squares structural equation modeling (PLS-SEM) for empirical estimations.

The authors' findings reveal that customers' innovativeness promotes continuance intention of using e-money and demonstrate that PBC partially mediates the relation between customers' innovativeness and continuance intention of using e-money. The empirical findings also reveal that PR negatively moderates the relationship between customers' innovativeness and continuance intention and the relationship between customers' innovativeness and PBC. The empirical findings also exhibit that perceived e-security enhances the degree of the relationship between customers' innovativeness and continuance intention and the relationship between customers' innovativeness and PBC.

The findings shed light on an important factor that increases the likelihood of repeat e-money usage and has direct managerial implications for customer experience and risk concerns. Hence, the findings imply that e-money service providers should run a promotional advertisement highlighting what additional features are included or offered and how these could be beneficial for the customers. Furthermore, e-money service providers should provide some tutorial videos in order to increase innovative customers' control over e-money services as well as highlight how risk and security are protected.

This paper integrates three key theories: the diffusion of innovation (DOI) theory, the theory of planned behavior (TPB) and the PR theory in post-adoption behavior of e-money usage. The current study also attempts to fill a literature gap by examining the moderating role of PR and e-security, which could be useful within the relationship between customers' innovativeness, PBC and customers' continued intentions of e-money usage.

The purpose of this paper is to introduce a conceptual framework that can facilitate investigations concerning the impact of marketing communication and financial consideration on the relationship between customer attitude and purchase intention of Islamic banking products and services.

This conceptual paper is structured based on the extant literature; it provides a review of theoretical perspectives, highlights the gap and illustrates the significance for developing a framework.

The authors identify notable patterns and limitations in previous empirical studies. Specifically, despite increasing interest in Islamic banking customer behavior, prior research has not given much attention to explore moderating effects on the customer attitude–intention link. This has left researchers and bank managers with very limited information to explain the conditions that enhance customers’ attitude and intentions toward Islamic banking products. Based on this backdrop, the paper displays a viable research model with propositions that assess potential moderating effects on the domain relationship.

This paper contributes to Islamic banking and management literature because prior research has predominantly focused on variables that directly influence customers’ behavior. This novel conceptual framework enables managers to better understand their customers and has implications for emerging themes, such as formulating strategies for specific customer groups and internationalization process. In addition, this paper provides a starting point to empirically examine whether and how the proposed moderators affect the link between customer attitude and behavioral intentions to purchase Islamic banking products.

To the best of knowledge, this is the first attempt to introduce relevant moderating variables for investigating the attitude and intention nexus in an Islamic banking context. Furthermore, the authors propose a new measure, namely, profit-loss sharing proportions which could enhance customers’ intention to purchase Islamic banking products.

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.

Higher education institutions (HEIs) play a pivotal role in fostering economic development by cultivating skilled workforce and generating knowledge and innovation. However, HEIs may pose a potential risk to sustainable economic development due to the generation of food waste inside their campus canteens. Therefore, this study aims to examine the influence of attitude, subjective norm (SN), perceived behavior control (PBC), religiosity and pro-social behavior among State Islamic Religious College (SIRC) students on their intention to avoid food waste behavior. This study also focused on the mediating role of the three original theory of planned behavior (TPB) variables and pro-social behavior in the relationship between religiosity and the intention to reduce food waste.

Questionnaires were used to collect data from 443 students at SIRC. The collected data were processed and analyzed using structural equation modelling to test direct, indirect and mediating effects.

The empirical results indicated that the eagerness of students at SIRC to reduce their behavior of leaving food behind can be driven by their negative attitudes or views toward food waste, the practice of religious teachings in their lives, the belief that they can avoid food waste and their concern for the environment. The empirical results reveal that even though religiosity influences SN, it is unable to strengthen the relationship between religiosity and the desire to be anti-food waste.

In addition to contributing to the food waste literature in the context of eating behavior, the results of this study have theoretical and practical implications.

To assess SIRC students’ behavioral intentions to avoid food waste behavior, this study used a contemporary setting to measure attitude, SN, PBC, religiosity and pro-social behavior, so strengthening the TPB’s empirical underpinning.

Small and medium-sized enterprises (SMEs) are an important contributor to emerging countries’ economic growth. However, SMEs have been struggling to sustain their performance in a highly competitive environment. Thus, this study aims to re-examine the effect of SMEs’ entrepreneurial orientation (EO) on firms’ performance during the COVID-19. This study has also studied the moderating role of social media usage and the mediating role of marketing capabilities and social media usage.

This study used a structured questionnaire for data collection, where the unit of analysis was the manager or owner of SMEs. The data were analyzed using partial least square-structural equation modeling.

The findings show that an EO has a significant and positive effect on an SME’s performance, but the outcomes are conditional on the role of social media and marketing capabilities. The empirical results reveal that marketing capabilities significantly mediate the relationship between EO and SME performance. In addition, social media usage moderates the relationship between EO and SME performance and it also partially mediates the EO-performance nexus of SMEs. Finally, this study discovers that the EO-Performance nexus of SMEs is serially mediated by social media usage and marketing capabilities.

This study has important implications for SMEs that are seeking to gain a competitive advantage. For example, an SME should deploy market activities through social media channels. In situations such as a pandemic and uncertainty, this could be the most effective tool.

This study builds a theory-based mediation-moderation model to explain the link between EO and SME performance. In explaining mediation-moderation effects, the current study provides insight into EO-performance relationships. Moreover, the current model facilitates exploring whether serial mediation passes through social media usage and market capabilities. Therefore, with new findings, the study extends the literature on serial mediation in the EO-performance of SMEs. Additionally, this study extends the literature on the moderating role of social media on SMEs in Indonesia, which has not been investigated. Besides, the current study adds new insight into the EO-performance of SME in COVID-19 condition.

The paper seeks to provide an adaptive fuzzy logic controller for permanent magnet synchronous motor (PMSM) under direct torque control (DTC) algorithm to minimize the torque ripple.

The design methodology is based on vector control analysis. MATLAB simulations supported with experimental study under C++ are used to execute the proposed work.

The results show that considerable torque ripple reduction as well as considerable current ripple reduction can be achieved by utilizing adaptive fuzzy switching algorithm to fire the inverter supplying the PMSM.

This research is limited to PMSM, however the research can be extended to include other AC motors as well. In addition, the following points can be studied, the effects of harmonics in control signals on the torque ripple. Digital and active filters as solution to these harmonics can be also addressed. The actual mathematical relation between the torque ripple and flux ripple can be studied to set the flux and torque bands width in reasonable value.

Based on existence DTC control system, it is only required to change the software‐switching algorithm, to provide smooth torque, given that the switching frequency of the inverter module is more than or equal to 15 kHz and the system is supplied with timers. In addition, a relatively higher DC voltage may be required to achieve higher speed compared with the traditional DTC.

In this paper, the stator flux position, and errors due to deviations from reference values of the torque and stator flux are used to select two active vectors while at the same time the absolute value of the torque error and the stator flux position are fuzzified to adapt the switching of the inverter in order to control the applied average voltage level in such a way as to minimize the torque ripple, so instead of fixed time table structure, a fuzzy logic is used to calculate the switching time for the selected vectors and no PI controller is used as the case in the traditional‐space vector modulation. This work is directed to motor drive system designers who seek highly smooth torque performance with fast response.
