Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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

Findings

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.

Research limitations/implications

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.

Practical implications

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.

Originality/value

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.
