Abstract

Purpose

The advancements of mobile technologies and devices have greatly facilitated the extension of online services from web to mobile environments. Drawing on the categorization theory, the purpose of this paper is to explore the impact of perceived entitativity on users’ web-mobile service extension behavior. The research model considers how perceived entitativity serves as a category cue to link the category- and piecemeal-based processing and shape users’ adoption of extended mobile services.

Design/methodology/approach

An online survey (n=552) was conducted to empirically test the model. The data were analyzed by structural equation modeling approach.

Findings

The results offer two major findings. First, performance expectancy, perceived controllability and subjective norm are important antecedents of users’ usage intention. Second, perceived entitativity has three types of effects on usage intention: it exerts a direct and positive influence on usage intention; it indirectly facilitates usage intention through increasing PE and perceived controllability; and it moderates the relationship between subjective norm and usage intention.

Originality/value

This study contributes to the literature by taking into account the interplay of category- and piecemeal-based processing to understand consumers’ web-mobile service extension behavior.

Abstract

Purpose

The engagement–addiction dilemma has been commonly observed in the information technology (IT) industry. However, this issue has received limited research attention in the information system (IS) discipline. Drawing on the stimulus–organism–response (SOR) framework, this study explores the engagement–addiction dilemma in the use of mobile games and highlights the impacts of game design features, namely, mobile user interface and mobile game affordance.

Design/methodology/approach

The research model was empirically validated using a longitudinal survey data from 410 mobile game users in China.

Findings

The empirical results offer several key findings. First, mobile user interface and mobile game affordance positively affect telepresence and social presence, which lead to meaningful engagement and mobile game addiction. Second, a high-quality of mobile user interface positively moderates the effects of mobile game affordance on telepresence and social presence.

Originality/value

This study contributes to the literature by theorizing and empirically testing the impacts of game design features on the engagement-addiction dilemma.

Abstract

Purpose

Drawing on the control agency theory and the network effect theory, the purpose of this paper is to examine the effect of privacy assurance approaches, network externality and technology complementarity on consumers’ self-disclosure in mobile payment (MP) applications. The authors identify four types of privacy assurance approaches: perceived effectiveness of privacy setting, perceived effectiveness of privacy policy, perceived effectiveness of industry self-regulation and perceived effectiveness of government legislation. The research model considers how these privacy assurance approaches influence privacy concerns and consumers’ self-disclosure in MP applications under boundary conditions of network externality and technology complementarity.

Design/methodology/approach

An online survey with 647 sample users was conducted to empirically validate the model. The target respondents were current consumers of a popular MP application. The empirical data were analyzed by a structural equation modeling approach.

Findings

The empirical results reveal several major findings. First, privacy assurance approaches can effectively decrease privacy concerns, which ultimately formulates consumers’ self-disclosure in MP applications. Second, network externality and technology complementarity weaken the effect of perceived effectiveness of privacy setting on privacy concerns. Third, network externality and technology complementarity strengthen the relationship between perceived effectiveness of government legislation and privacy concerns, while they have non-significant interaction effect with perceived effectiveness of privacy policy and industry self-regulation on privacy concerns.

Practical implications

MP providers and stakeholders can harness the efficacy of privacy assurance approaches in alleviating privacy concerns and promoting consumers’ self-disclosure in MP applications.

Originality/value

The authors’ work contributes to the information privacy literature by identifying effective privacy assurance approaches in promoting consumers’ self-disclosure in MP applications, and by highlighting boundary conditions of these privacy assurance approaches.

Abstract

Purpose

Drawing on the social learning theory, the purpose of this paper is to examine the antecedents and consequences of users’ excessive online social gaming. Specifically, the authors develop a model to propose that observational learning and reinforcement learning mechanisms together determine excessive online social gaming, which further foster adverse consequences.

Design/methodology/approach

The model is empirically validated by a longitudinal survey among users of a popular online social game: Arena of Valor. The empirical data are analyzed using component-based structural equation modeling approach.

Findings

The empirical results offer two key findings. First, excessive online social gaming is determined by observational learning factors, i.e. social frequency and social norm, and reinforcement learning factors, i.e. perceived enjoyment and perceived escapism. Second, excessive online social gaming leads to three categories of adverse consequences: technology-family conflict, technology-work conflict and technology-person conflict. Meanwhile, technology-family conflict and technology-work conflict further foster technology-person conflict.

Originality/value

This study contributes to the literature by developing a nomological framework of excessive online social gaming and by extending the social learning theory to excessive technology use.

Abstract

Purpose

Crowdworkers' sustained participation is critical to the success and sustainability of the online crowdsourcing community. However, this issue has not received adequate attention in the information systems research community. This study seeks to understand the formation of crowdworker sustained participation in the online crowdsourcing community.

Design/methodology/approach

The research model was empirically tested using online survey data from 212 crowdworkers in a leading online crowdsourcing community in China.

Findings

The empirical results provide several key findings. First, there are two different types of sustained participation: continuous participation intention (CPI) and increased participation intention (IPI). Second, extrinsic motivation and intrinsic motivation positively influence crowdworker CPI and IPI. Third, community commitment negatively moderates the effects of extrinsic motivation on CPI and IPI, while it positively moderates the effects of intrinsic motivation on CPI and IPI.

Originality/value

This study has significant implications for research on online crowdsourcing community and provides practical guidance for formulating persuasive measures to promote crowdworker sustained participation in the community.

Abstract

Purpose

Drawing from the spillover effect literature, the purpose of this paper is to investigate the spillover effect in consumers’ web-mobile payment extension behavior. The authors figure out two categories of factors associated with the spillover effect: relevant schema and schematic fit. Cognitive trust and emotional trust in web payment are used to capture relevant schema, while perceived similarity and perceived business tie are proposed to denote schematic fit in the web-mobile payment extension context.

Design/methodology/approach

An online survey (n =552) was conducted to empirically test the model. The data were analyzed by structural equation modeling approach.

Findings

The results show that relevant schema and schematic fit factors positively influence perceived value of mobile payment (MP), which facilitates consumers’ behavioral intention of MP.

Originality/value

This study contributes to the extant literature by theoretically identifying the key factors of the spillover effect and empirically investigating its role during the web-mobile service extension process.

Abstract

Purpose

In the limited existing research on smartphone addiction, reinforcement reward and automatic habit have been identified as two distinct underlying mechanisms. The purpose of this paper is to better understand the interaction between these two mechanisms, as well as role of smartphone features in activating different formation mechanisms.

Design/methodology/approach

An online survey with 379 samples was conducted to empirically validate the model. The data were analyzed by structural equation modeling approach.

Findings

The automatic habit strengthens the driving effects of reinforcement rewards (i.e. perceived enjoyment and mood regulation) on smartphone addiction. Smartphone features activate distinct underlying mechanisms. Value-added function facilitates the perception of reinforcement rewards, while convenience promotes the habit formation.

Originality/value

This study is one of the first ones that assess the interplay between the two formation mechanisms in the extant literature on smartphone addiction. This study also reveals the dangers of smartphone features which have always been regarded as advantages. The findings contribute to the current understandings of smartphone addiction.

Abstract

Based on a lumped mass model and an incremental iteration method, an efficient simultaneous iteration procedure is developed for the finite element solution of the enthalpy model. This procedure uses Gauss elimination to solve the resulting algebraic equation system. A one‐point quadrature program based on the isoparametric quadrilateral element is incorporated for the calculation of the heat conductance matrix, leading to a significant reduction of the computation time.

Abstract

This paper presents a two‐dimensional finite element model for convection‐dominated melting and freezing problems. The enthalpy‐porosity approach is utilized to account for the physics of the evolution of the melt velocity at the solid/liquid phase change interface. Penalty formulation is employed to treat the incompressibility constraint in the momentum equations. The streamline upwind/Petrov Galerkin method is used in combination with primitive variables to solve the governing equations. Simulations are carried out for melting of a pure phase change material in a rectangular cavity heated from below. Sample results are presented and discussed.

Abstract

In the original effective heat capacity method the latent heat effect is approximated by a large effective heat capacity over a small temperature range. This method is simple in concept and easy to implement. However, it is so sensitive to the choice of the phase change temperature interval and the chosen time integration scheme that non‐convergence always occurs when it is implemented with implicit time integration schemes. Presents the cause and cure of non‐convergence in effective heat capacity methods and discusses sample results.
