Abstract

Purpose

This study aims to assess the use of variational quantum imaginary time evolution for solving partial differential equations using real-amplitude ansätze with full circular entangling layers. A graphical mapping technique for encoding impulse functions is also proposed.

Design/methodology/approach

The Smoluchowski equation, including the Derjaguin–Landau–Verwey–Overbeek potential energy, is solved to simulate colloidal deposition on a planar wall. The performance of different types of entangling layers and over-parameterization is evaluated.

Findings

Colloidal transport can be modelled adequately with variational quantum simulations. Full circular entangling layers with real-amplitude ansätze lead to higher-fidelity solutions. In most cases, the proposed graphical mapping technique requires only a single bit-flip with a parametric gate. Over-parameterization is necessary to satisfy certain physical boundary conditions, and higher-order time-stepping reduces norm errors.

Practical implications

Variational quantum simulation can solve partial differential equations using near-term quantum devices. The proposed graphical mapping technique could potentially aid quantum simulations for certain applications.

Originality/value

This study shows a concrete application of variational quantum simulation methods in solving practically relevant partial differential equations. It also provides insight into the performance of different types of entangling layers and over-parameterization. The proposed graphical mapping technique could be valuable for quantum simulation implementations. The findings contribute to the growing body of research on using variational quantum simulations for solving partial differential equations.

Abstract

Corruption has been defined in different ways by various scholars and organizations according to cultural, legal, or other factors (Organization for Economic Co-operation and Development, 2008, p. 22). The word “corruption” is derived from the Latin word corruptus and, according to the dictionary, it has six possible meanings: dishonesty for personal gain; depravity; undesirable change; corrupting of something; altered word or phrase; or rotting.1 However, the most useful typology of contemporary social science definitions of corruption is Arnold J. Heidenheimer's typology of three major types of definitions (Heidenheimer, 1970, pp. 4–6).

Abstract

Purpose

This study proposed and tested three comprehensive models of the usage intention of proximity mobile payment services after a government regulation, by integrating the theory of planned behaviour (TPB) and the norm-activation model (NAM). The purpose of this paper is to investigate the effects of moral norms, merchant pro-activeness and perceived government regulation (demonetisation) on users’ continuance intention of proximity mobile payment services.

Design/methodology/approach

In total, 387 users of proximity mobile payment services in India were surveyed using a structured questionnaire. This study was carried out with shoppers in the Mumbai Metropolitan Region and New Delhi because of the diverse and large population of these cities.

Findings

The results of this study indicated that: integrating the variables of NAM into the original TPB model enhanced the prediction effect; perceived demonetisation regulation exerted a direct determinant effect as well as moderate effect on continuance usage intention of mobile payment services; also, extended TPB model with perceived demonetisation regulation as moderator could satisfactorily predict the continuance usage intention.

Research limitations/implications

The results provided insightful evidence for the government and policymakers to outline more effective mandatory regulation policies.

Originality/value

This investigation attempts to enhance the theoretical understanding of the antecedents of in-store proximity mobile payment services after government regulation (demonetisation) in India.

Abstract

Purpose

Mobile shopping is expected to emerge as a new way of shopping as the Asia Pacific region moves towards the digital era. It is important to understand factors that influence consumers’ intentions to adopt this new shopping channel, especially in developing countries such as Malaysia where it has the fastest growing mobile penetration rate in the world. The purpose of this paper is to integrate the Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB), and includes additional variables such as personal innovativeness (PI) and trust.

Design/methodology/approach

Empirical data from 453 consumers were tested against a proposed model using partial least squares structural equation modelling.

Findings

Findings suggest that most of the constructs in the model (i.e. trust, perceived ease of use, perceived usefulness, attitudes, PI and perceived behavioural control) influence a shopper’s intentions towards adopting mobile shopping. For example, consumers’ attitudes towards M-shopping adoption is higher if a system is not complex and easy to use; if consumers can easily pull out their mobile devices from their pockets to browse or shop by using just one finger, without a complicated process, they tend to use M-shopping channels. In addition, when mobile technology is user-friendly and free from mental effort, it creates positive perceptions that the system is useful, developing stronger intentions for consumers to adopt this alternative.

Originality/value

Since M-shopping is a personalised activity that involves money transactions, consumers are more cautious with adoption intentions, and do not follow social norms blindly. Thus, the empirical evidence from Malaysian consumers contributes to literature with insights into their specific m-shopping behaviour in this emerging market. In addition, from a theoretical perspective, the research model in this study integrates both TAM and TPB to provide a holistic view of consumers’ M-shopping adoption intentions in an emerging market, incorporating user-centric factors (i.e. trust and PI). An important finding which differs from other studies is that the relationship between subjective norms and behavioural intention to use M-shopping was not significant, which is contrary to the findings of previous studies. Moreover, attitude was found to mediate the effect of PEOU and PU on consumer’s intention towards mobile shopping adoption. The validated instrument would serve as a useful guideline for researchers during development and refinement of studies on M-shopping.

Abstract

Purpose

This empirical study aims to determine factors that influence an individual’s intention to use mobile payment (MP) systems. The study investigates direct, indirect and total effects as well as factors that mediate or moderate effects on intention.

Design/methodology/approach

A theoretical model is derived from previous studies and combines factors from technology acceptance model and unified theory of acceptance and use of technology (perceived usefulness, perceived ease of use, social influence, facilitating conditions, behavioral intention) with factors relevant to MP (perceived security, uncertainty avoidance, trust, network externalities and self-efficacy). Gender, age, MP experience and income are included as moderators of direct effects on behavioral intention. The sample includes 736 participants from the four large cities in Indonesia. Structural equation modeling is used to analyze and develop the theoretical model.

Findings

Self-efficacy has the greatest total effect on behavioral intention, followed in decreasing order of importance by perceived usefulness, perceived ease of use, social influence, trust, network externalities and uncertainty Avoidance. only gender and MP experience have significant moderating effects whereby the direct effects of self-efficacy and network externalities on behavioral intention are influenced by gender and MP experience, respectively. Trust, perceived usefulness and perceived ease of use have important mediation effects.

Originality/value

This study fills the gap in the limited theoretical understanding of MP adoption in Indonesia. New theoretical findings related to mediating and moderating effects, direct, indirect, and total effects are used to discuss important practical implications of the findings.
