  • An integrated model of the antecedents and consequences of perceived information overload using WeChat as an example   Order a copy of this article
    by Liang Ma, Xin Zhang, Gao Shan Wang, Ge Zhang 
    Abstract: In recent years, more and more social media users have complained of information overload. In this paper, we obtained data from surveys of users of the multi-purpose Chinese social website, WeChat, to develop an integrated model of information overload. The model was used to determine the antecedents and consequences of WeChat users' perceived information overload. A field survey of 244 WeChat users was conducted to test the research model and hypotheses. The results showed the following key findings: 1) the amount of information received and the length of content increased users' perceptions of information overload, while the number of WeChat subscriptions followed was not a significant factor; 2) users' perceptions of information overload were associated with negative emotions and increased intention to discontinue usage; 3) the type and severity of negative emotions and consequent likelihood of discontinuing usage will vary according to the users' different levels of experience. The implications of our results for researchers, website managers and psychosocial practitioners are discussed.
    Keywords: perceived information overload; number of subscription follow; amount of information received; length of information; negative emotion; discontinuous usage intention.

    by Chi-Hsuan Lin, Kuang-Hsun Shih, Wei-Chuan Wang, Lee-Fen Chuang, Wei-Chun Tsai, Chung-Fu Huang 
    Abstract: By adopting the Davis's technology acceptance model and introducing the variables of system quality, information quality, and service quality from the information system success model, this study's purpose is to combine these two models to explore the factors that influence consumers to purchase travel insurance through the mobile banking system. In our entire study process, total 300 survey questionnaires were collected, approaching a response rate of 100%. Due to the insufficient number of samples and this is a new issue, it may lead to insufficient statistical analysis. Moreover, the number of valid questionnaires was 261, approximately 87% of the response rate. Research results show the following: in our hypothesis test, only one of the 12 hypotheses is not valid. Last, the study provides recommendations and directions for the financial industry to use as reference when promoting mobile banking operations in the future.

  • Exploring factors affecting the adoption of Mobile Payment at physical stores   Order a copy of this article
    by Lin Wang, Xuefeng Dai 
    Abstract: This study develops and empirically tests a research model to comprehensively examine factors influencing the adoption of mobile payment at physical stores. In particular, this study proposes an integrated theoretical framework that combines the theory of technology acceptance model (TAM) and unified theory of acceptance and use of technology (UTAUT). The results indicate that: attitude is the most important factor influencing users’ intention to adopt offline mobile payment compared to perceived usefulness and social influence; personal innovativeness, perceived usefulness and promotional offer also have significant effects on attitude whereas the perceived ease of use is not as important as others but does with significant effect on perceived usefulness.

  • Customer Resistance to Churn in a Mature Mobile Telecommunications Market   Order a copy of this article
    by Younghoon Chang, Seungyeon Kim, Siew Fan Wong, Myeong-Cheol Park 
    Abstract: Effective customer retention is critical for company survival, especially in a mature mobile telecommunications market. To build on customer retention research, we propose an integrative model capturing the dual relational mechanisms that explain customer resistance to churn. We empirically test the model using data from 815 subscribers who have stayed with their mobile network operators for more than three years. The results show that two contrasting mechanisms, dedication-based and constraint-based relationships, simultaneously determine customer resistance to churn. The constraints of procedural, financial, and relational costs significantly influence perceived risk, while dedication factors of economy-based and identification-based trust significantly influence commitment.
    Keywords: resistance to churn; customer retention; constraint-based relationship; dedication-based relationship.

  • A Multi-Modal Approach for Evaluating Player Experience on Different Gaming Platforms   Order a copy of this article
    by Yavuz Inal, Kerem Rızvanoğlu, Çakır Aker 
    Abstract: The aim of this experimental study was to adopt a multi-modal approach to analyse player experience on PC and mobile gaming platforms, and identify both the factors that potentially have an effect on this experience and the set of methods that are effective on measuring it. Game experience questionnaire was enriched through usability scales, semi-structured interviews and player observations. Data was collected from 20 undergraduate university students that were selected from casual gamers that had never played the Plants vs. Zombies game before. Results of the study showed that participants who played on the PC platform declared more positive feelings when compared to the players of the mobile platform. The bivariate correlations between the game experience items on each platform showed that flow, competence, and challenge were the marker components of game experience that differed due to the players' game experience on each platform.

    by Mehmet Cem Bölen, Üstün Özen 
    Abstract: This study aims to determine the factors affecting the continuance intention in using mobile shopping apps and websites. Within the scope of the study, a research model is proposed that integrates an information systems (IS) expectation-confirmation model (ECM), flow theory, and trust. Structural equation modelling (SEM) was employed to analyse data collected from 518 users of the most popular private shopping clubs in Turkey. The results revealed that the variables of perceived usefulness, satisfaction, and enjoyment directly and significantly affected the consumers' continuance intention in using the private shopping clubs' mobile apps and websites. The focus dimension of the flow experience was not found to have a significant effect on either consumer satisfaction or continuous usage intention. Another interesting result of the study is that, contrary to the general belief in the literature, the trust dimension does not have a significant effect on consumers' continuance intention.

  • MULTIMODAL SYSTEMS FOR SPEECH RECOGNITION   Order a copy of this article
    by Orken Zh. Mamyrbayev, Dinara Mussayeva, Bagashar Zhumazhanov, Farida Gusmanova, Keylan Alimhan, Beibut Amirgaliyev 
    Abstract: In this article, we have implemented a system of multimodal recognition of Kazakh speech, based on speech and lip recognition. During the feature extraction phase, several methods have been used, such as voice activity detection (VAD), mel-frequency cepstral coefficients, perceptual linear prediction, relative perceptual linear prediction, and their first-order time derivatives. The main problems of recognition of Kazakh speech, VAD algorithms and speech segmentation, lip movement recognition are considered in the article. The description of probabilistic modelling of audiovisual speech based on coupled hidden Markov models (HMMs), information fusion methods with weight coefficients for audio and video speech modalities, and parametric representation of signals is provided. Quantitative results in multimodal recognition of continuous Kazakh speech indicate high accuracy and reliability of the automatic system. This approach has been used and compared in terms of computational time and recognition speed and gives very interesting results.

  • Effects of Virtual Reality News on Knowledge Gain and News Attitudes   Order a copy of this article
    by Yoori Hwang, Se-Hoon Jeong, Sonho Kim, Jung-Yoon Yum 
    Abstract: This research examined the effects of virtual reality (VR) news on knowledge gain and news attitudes. This study found that compared to non-VR news, VR news could have a negative impact on knowledge gain, whereas it could have some positive effect on news attitudes. The positive effect on news attitudes was only found with a more experience-related news topic (i.e., travel sites in Rio de Janeiro), but not with a less experience-related news topic (i.e., new surgical procedure for pancreatic cancer). The positive impact of VR on news attitudes was mediated by presence and subsequent enjoyment.

  • Use of social networking applications (SNAs) by immigrant children, adolescents, and young adultsto maintain contact with those who remained in the country of origin: Usage characteristics and habits   Order a copy of this article
    by Zilka Gila 
    Abstract: In the present research, we examined the use and its influence of social networking applications on the process of young immigrants' acclimatisation in Israel, given the widespread use of such applications by children, adolescents, and young people to maintain contact with those who remained in their country of origin. This is a mixed-method study. A total of 551 participants from Israel completed questionnaires, of whom 110 were also interviewed. Interviewees were asked to clarify the quantitative findings to help gain in-depth understanding of the factors affecting acclimatisation. The semi-structured interviews covered all the topics included in the research questionnaires. The interviewees wanted to share positive and negative experiences they lived through, and some provided detailed descriptions. The study found that participants feel that communication alleviates the sense of longing, enables intimate discourse, sentiment sharing, release of anger, and relief of frustration. The use of web applications encourages significant interactions with those who remained in the country of origin, but to a certain extent causes social isolation in the new country.

  • What customers want from smart devices: Investigating explicitly judged and implicitly derived success factors   Order a copy of this article
    by Kyungdoh Kim, Robert W. Proctor, Chang-Soo Ok 
    Abstract: Smart devices are gaining popularity, and success of such products requires understanding customer requirements. To investigate success factors of smart devices, we conducted two survey studies regarding cell phones, tablet computers, and laptop computers. First, we determined explicit judgements of success factors through pairwise comparison of various factors. Second, we derived success factors implicitly by having users evaluate their own smart devices. Finally, we compared these two results and finalised the success factors for smart devices, which include the following. People want to repurchase innovative smart devices with good design. Products with competitive advantage and good usability that meet customer needs are recommended by individuals who have used them. Also, products with good market conditions will typically succeed.

  • What drives students’ online self-disclosure behavior on social media? A hybrid SEM and artificial intelligence approach   Order a copy of this article
    by Ibrahim Arpaci 
    Abstract: This study investigated drivers of the online self-disclosure behaviour on social media by employing a complementary structural equation modelling (SEM) and artificial intelligence approach. The study developed a theoretical model based on the 'theory of planned behaviour' (TPB) and 'communication privacy management' (CPM) theory. The predictive model was validated by employing a multi-analytical approach based on the data obtained from 300 undergraduate students. The model focused on the role of security, privacy, and trust perceptions in predicting the attitudes toward the selfie-posting behaviour. The results suggested that privacy and security are significantly associated with the trust, which explains a significant amount of the variance in the attitudes. Consistently, results of the machine-learning classification algorithms suggested that attributes of the security, privacy, and trust could predict the attitudes with an accuracy of more than 61% in most cases. Further, mediation analysis results indicated that privacy has no direct effect, but an indirect effect on the attitudes. These findings suggested a trade-off between the privacy concerns and perceived benefits of the actual behaviour.

  • A Comparative Analysis and Performance Evaluation of Web Application Protection Techniques against Injection Attacks   Order a copy of this article
    by Nabeel Salih Ali, Ahmed Hazim Alhilali, Mohammed Falih, Salam Kadhim, Hayder K. Fatlawi, Abdul Samad Bin Shibghatullah 
    Abstract: Nowadays, most animation activities are based on internet-enabled applications. But, the majority of web developers have ignored the privacy and security aspects of each application, turning them into attractive targets for security issues and therefore increasing the attacker's concerning. Structured query language injection attack (SQLIA) is the prevalent and dominant type of severe web application attacks. This paper provides a comparative study for web application protection techniques and evaluates their performance against SQLIA by conducting a detailed review of various SQLIA previously detected and prevented by protection techniques, a summary and analysis of a critical review of the defensive techniques that were done to address such attack, performance comparison of the different protective approaches through an evaluation using performance metrics to identify efficient and high-performance techniques. Finally, the paper highlights and focuses on the critical and vital directions or protection approaches that require more studies by future research.

  • A Longitudinal Study on the Effects of Motivational Mobile Application Uses on Online News Engagement   Order a copy of this article
    by Ji Won Kim, Sunyoung Park, Yoonmo Sang 
    Abstract: Based on four-wave panel data, this study explored the relationships between different uses of motivational mobile applications and online news engagement. Three motivational mobile application uses informational, recreational, and relational were identified and rank-ordered according to respondents everyday mobile application preferences. Results showed that only relational mobile application use had positive relationships with online news engagement. Results further indicate that over the four-year period examined (20132016) only the use of relational mobile application led to continuous growth of online news engagement. This study advances the literature on mobile communication not only by introducing results of a longitudinal study that challenge and support conflicting previous findings but that also provide support for the possibility of the mobile facilitation hypothesis.

  • Examining Academic Landscape of Mobile Banking   Order a copy of this article
    by Hai-Yen Chang, John S. Liu, Ching-Wen Lin, Vincent C. Ma 
    Abstract: This study aims to identify trends in mobile banking (MB) research by reviewing influential academic articles. We adopted content analysis as a qualitative methodology and main path analysis as a quantitative methodology, to portray the development of MB research over the period from 1990 to 2016. We identified 14 highly influential articles in the evolution of MB literature. We found that the majority of the articles were written in an Asian context. The predominant theme shifted from MB adoption to the impact of MB on the effectiveness of individual lives. The primary concern of MB users changed from risk to usefulness, especially among the young users. The implications for financial institutions include focusing on consumer lifestyle, monitoring security measure and communicating to college students as the main potential customers.

  • Investigating the adoption intention of gamification apps on mobile services   Order a copy of this article
    by Tony Cheng-Kui Huang, Ya-Wen Lee, Shin-Horng Chen 
    Abstract: Previous studies exploring adoption in the field of management information systems have focused on the objects of information systems or information technologies. However, since the popularity of smart phones has led to the usage of apps, limited investigations have attempted to understand the usage intention of apps. In this study, a research model is proposed to comprehend how users perceive and adopt a gamification app in the initial adoption phase of the information system life cycle. Since there are various topics within gamification services, we only pinpoint one popular type of service, exercise, as the research subject. The investigation involving 173 usable subjects was conducted to evaluate the model by using structural equation modelling. The result demonstrates that our proposed model explains 56.7% of the variance. The findings have interesting implications with respect to the initial usage of exercise gamification apps, both for researchers and practitioners.

  • Understanding users’ intention to switch mobile instant messaging   Order a copy of this article
    by Shuang Cheng, Sang-Joon Lee 
    Abstract: In recent years, mobile instant messaging (MIM) has become increasingly popular and has integrated in the daily lives of millions of people worldwide. Previous studies on MIM have primarily focused on its initial adoption and continuance usage, while paying less attention to switching behaviour. This study aims to explore the key factors influencing users’ switching intention of MIM in China, using the push-pull-mooring (PPM) framework of the migration theory, and empirically examine the three types of predictors for MIM switching intention: push (fatigue), pull (referent network size, future expectation, complementarity, and transfer trust), and mooring (switching cost) factors. Our results indicated that all of these factors have significant effects on switching intention. The results yield both theoretical and practical implications.

    by Ching-Wen Lin, Tung-Hsien Wu, Shaio Yan Huang 
    Abstract: Research has primarily focused on the security aspect of mobile communication for computer auditing research in the mobile industry. Few studies have examined the role of computer auditing on the mobile industry. Therefore, the current study investigated the mediating effect of computer audit on the correlation between relationship quality and information security by conducting a survey using the partial least-squares method. Computer audit directly influenced internal auditing performance, and relationship quality indirectly influenced information security through computer audit. Therefore, determining how sound computer auditing can be conducted is crucial for the internal audit department.

  • A survey of what customers want in smartwatch brand applications   Order a copy of this article
    by Kyungdoh Kim, Kyeongjin Park, Meuel Jeong 
    Abstract: This research explores how smartwatch brand apps can be used to advertise companies and brands. A survey was conducted to analyse the utilisation of the brand app in smartwatch, and a total of 134 data were collected. Study 1 discovered the external factors that influence intention to use and tracked the relationship between factors using technology acceptance model. The results of the structural equation model analysis showed that the ease of use had a significant positive impact on the intention to use and the complexity and financial risk had a statistically negative impact on the intention to use. Study 2 investigated what types of smartwatch brand apps users would use. As a result of analysis of variance, music, weather information, basic telephone function, SNS, navigation, basic SMS, productivity, and health showed higher use intention. Types with low intentions were e-books, games, sports, entertainment, QR code/barcode recognition, finance, photography and video.

  • Social network services and their effects on network social capital: An instrumental variables approach   Order a copy of this article
    by KYUNG-GOOK PARK, Sehee Han 
    Abstract: The purpose of this study is to examine the association between social network services and network social capital while adopting an instrumental variables approach. This study includes a simple random sample of 491 respondents gathered through a cross-sectional survey in South Korea. The results show that users of social network services were higher in their network social capital in comparison with non-users of social network services. The results further suggest that it is high intensity users rather than low intensity users who are higher in network social capital than non-users of social network services. The current study contributes to the literature as it empirically investigates the association between social network services and network social capital, while including non-users of social network and tackling the possible endogeneity problem of the usage of social network services.

  • Enhancing the Performance of Service Discovery Protocol Using Minimum Spanning Tree   Order a copy of this article
    by Cynthia Jayapal, Senthil Jayavel, Vanitha V 
    Abstract: In a wireless sensor network, aggregation is either done to avoid the redundant transmissions. In service provisioning, the control packets sent for service advertisement and discovery contribute significantly to the network traffic. In this paper, it is proposed to aggregate the similar control packets sent from different sources to a common destination along with minimum spanning tree, which is constructed for service provisioning. The mobile agent migration schemes used in the literature have got overhead in finding the migration path. Therefore, the proposed approach uses the spanning tree constructed for service discovery, as the migration path for the mobile agents. It is found from the investigation that the aggregation scheme has reduced average energy spent by 33%, control overhead by 12% and average discovery delay by 25%. Use of mobile agents has reduced the average discovery delay by 22%, control overhead by 19% and service discovery success ratio by 4%.

  • The Perspective of Information System Success with Social Interaction on Online Game Continuance: The Moderating Role of Gender, Age, and Play Frequency   Order a copy of this article
    by Shih-Chih Chen, Chih-Hung Wu, Chao-Wei Lai 
    Abstract: This study proposed a modified hypothetical model to investigate the influence among six dimensions, namely, system quality, game quality, privacy protection service, user satisfaction, benefits of social interaction, and continuance usage intention. Besides, this study included gender, age, and usage frequency as moderators in the proposed model. The results showed that system and game quality significantly influenced the satisfaction and benefits of social interaction on online game players, as well as their continuance intention toward online games. The modified D&M IS success model significantly predicted the intention of online game players to continue playing an online game product. In addition, high frequency online game players show the significantly stronger influence of system quality on benefits of social interaction than low frequency online game players. This study provided a better understanding of the relationship about the factors how to influence the online games continuance intention for academics and practitioners.

  • The roles of motivation and media engagement in second-screen viewing experiences   Order a copy of this article
    by Cheng-yu Lin, Po-chien Chang 
    Abstract: Traditional TV viewing has been blended with the use of second-screen mobile devices. Increased engagement via mobile devices or applications has quickly become a new norm interacting with program-related information (e.g., following fan community or play related games) or chatting on social apps (e.g., Twitter) while watching television (TV). New features and behaviours are emerging that create challenges and opportunities for attracting advertising revenues and viewer attention in the second-screen environment. This study explored the antecedent and consequences of second-screen mobile phone use. Four categories, control, enrichment, sharing, and participation, were identified as second-screen TV viewing behaviours. An empirical model was developed by integrating audiences motivation, media engagement and second-screen behaviour. A response from 562 TV audience participants were collected and reveals that audience motivation for using a second screen is mainly affected by their engagement experiences, and further led to the corresponding usage behaviours. Mobile users, motivated by common interests and social sharing, are more engaged in online activities while watching TV programs. Second screen users are also obsessed with their social connectivity experiences rather than interactive features of TV programs. Theoretical and practical implications for effective second screen strategies are discussed.

    by Martin Brodin, Jeremy Rose 
    Abstract: Information security management researchers are often focused on the information security policy, its implementation and evaluation as the primary means of ensuring that organisations protect their valuable data. However, information security is usually nested with a variety of other concerns (for instance technology upgrades, information access, efficiency and sustainability issues, employee satisfaction), so this policy-driven approach is seldom operated in isolation. We investigate the approach as implied in the mobile information security literature, provide a literature-inspired characterisation and use it to analyse an iPad implementation for politicians in a Swedish municipality. The analysis provides only a partial explanation for security work in this kind of small organisation technology upgrade, so we develop a complementary approach: the evolving implementation approach. A suggestion is made for how the two approaches can be reconciled, and implications for both practitioners and researchers derived.

  • A Provably Secure Pairing-free Anonymous Handover Authentication Protocol For Mobile Wireless Networks   Order a copy of this article
    by Sunday Ogundoyin 
    Abstract: To address the limitations in the existing anonymous handover authentication (AHA) protocols, we propose a novel certificateless-based public key cryptography (CL-PKC) AHA protocol using elliptic curve cryptography (ECC). The protocol can achieve all the security requirements of AHA protocol and provide countermeasure against privilege escalation. The beauty of our protocol is that it is autonomous, where nodes only need to contact the authentication server (AS) once for pseudonym set and thereafter they can renew their pseudonyms on their own. The formal protocol analysis shows that the protocol achieves mutual authentication and session key establishment. Moreover, we show that the protocol is secure in the random oracle model based on elliptic curve discrete logarithm assumption (DLA). The performance evaluation demonstrates that the proposed AHA protocol is very efficient in terms of computation cost and communication overhead than related protocols.

  • An investigation of perceived value dimensions: implications for mobile marketing research   Order a copy of this article
    by Lijuan Huang, Jian Mou, Kai S. Koong, Yueping Du 
    Abstract: This study proposes a framework to investigate the multiple dimensions of consumer value in the context of mobile marketing, to better understand the factors impacting on mobile consumer perceived value. We primarily conducted a series of interviews based on means-end chain theory and in line with the interviews of 179 WeChat official account subscribers. Then, three-step surveys are taken; after revision and testing, the proposed scale and the final six-dimensional model (MCPV scale) emerged. In addition, another study was conducted to validate the scale model, which takes mobile advertising effectiveness, attitudes towards the official account and loyalty towards the official account as consequences of MCPV. The MCPV scale was found to be both reliable and valid; it had significant influence on mobile advertising effectiveness, and it could serve as a framework for further empirical research in the mobile marketing settings. Lastly, theoretical and practical implications were discussed.

  • Effects of personal innovativeness on mobile device adoption by older adults in South Korea: the moderation effect of mobile device use experience   Order a copy of this article
    by Mi Sook Lee 
    Abstract: This paper examines mobile device adoption by older adults in South Korea, one of the fastest ageing countries in Asia. It is important to understand how older adults perceive the use of mobile devices and the extent of their intention to continuously (or newly) use them. This paper includes personal innovativeness in the technology acceptance model (TAM) to better investigate mobile device use among older adults. The research model was empirically analysed using structural equations modelling (SEM). The results show that: 1) perceived ease of use (PEOU) and perceived usefulness (PU) partially mediate the relationship between personal innovativeness (PI) and behaviour intention (BI); 2) perceived ease of use (PEOU) has a stronger effect on behaviour intention (BI) than perceived usefulness (PU) does; 3) the use experience of mobile devices plays a moderating role in several paths of the proposed model; 4) invariance analysis reveals interesting and unexpected results.

  • Multi-view video codec using compressive sensing for wireless video sensor networks   Order a copy of this article
    by Veeraputhiran Angayarkanni, S. Radha, V. Akshaya 
    Abstract: In monitoring applications, different views are needed to be captured by multi-view video sensor nodes for understanding the scene clearly. These multi-view sequences have large volume of redundant data which affects the storage, transmission, bandwidth and lifetime of wireless video sensor nodes. A low complex coding technique is required for addressing these issues and for processing multi-view sensor data. Hence, in this paper, a framework on CS-based multi-view video codec using frame approximation technique (CMVC-FAT) is proposed. Quantisation with entropy coding based on frame skipping is adopted for achieving efficient video compression. For better prediction of skipped frame at receiver, a frame approximation technique (FAT) algorithm is proposed. Simulation results reveal that CMVC-FAT framework outperforms the existing method with achievement of 86.5% reduction in time and bits. Also, it shows 83.75% reduction in transmission energy compared with raw frame.
    Keywords: multi-view encoding; compressed sensing; CS; distributed video coding; DVC; frame approximation; wireless video sensor networks; WVSNs.

    Abstract: This study aims to contribute to making customer satisfaction measurement more efficient in the mobile phone sector. For this purpose, data were collected from 3,342 mobile phone users living in five different cities in Turkey. A self-administered questionnaire was used in this study. Five different surveys were used, with the same questions but with different categories of response (4-, 5-, 6-, 7-, and 10-point scales). The research instrument items were adapted from the American customer satisfaction index (ACSI). With the dataset of each response category, the models were installed and subsequently compared. The originality of the study is due to the comparison of the models created with different datasets. According to the findings obtained, different response categories did not make a considerable difference in the measurement of customer satisfaction.
    Keywords: customer satisfaction; American customer satisfaction index; ACSI; response categories; mobile phone sector.
