Understanding users intention to switch mobile instant messaging
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.
Keywords: mobile instant messaging; fatigue; network externality; transfer trust; switching cost; switching intention; push-pull-mooring framework.
A simple and portable add on converter module for communication and measurements
by Dinesh Kumar, Majo Mary Mathew, Madhusoodanan Kottarathil Naduvil
Abstract: This paper presents the development of a new versatile portable add-on converter module which can be used for analysing mobile communication and cable TV networks. Present testing techniques required separate test equipment for characterising electrical and optical networks. Here, we develop a new system work as an add-on module for electrical frequency domain reflectometer which can perform measurements in electrical as well as optical cable networks. Using this technique, millions of electrical cable analyser currently in use all over the world can be converted into the optical analyser. The same system can also be configured as a bidirectional communication system for a wide variety of applications like fibre to the antenna/fibre to the home, cable TV applications. We also show that the developed system has wideband performance over a frequency range from 800 MHz to 2.5 GHz and a dynamic range of 45 dB.
Keywords: Converter module; electrical frequency domain reflectometer; radio over fiber; single-mode fiber; multimode fiber.
Relationship Quality, Computer auditing and information security for mobile industry
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
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.
Keywords: Smartwatch; Advertisement; Brand app; Intention to use; TAM.
Social network services and their effects on network social capital: An instrumental variables approach
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.
Keywords: network social capital; social network services; instrumental variable approach; treatment effects model; technology acceptance model.
Enhancing the Performance of Service Discovery Protocol Using Minimum Spanning Tree
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
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
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.

MOBILE INFORMATION SECURITY MANAGEMENT FOR SMALL ORGANISATION TECHNOLOGY UPGRADES: THE POLICY-DRIVEN APPROACH AND THE EVOLVING IMPLEMENTATION APPROACH
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
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.

A Scientometric Analysis on Mobile Recommender Systems
by Kasra Madadipouya, Liyana Shuib, Suraya Hamid
Abstract: With further advancements in technology, a new emerging topic called mobile recommender systems has gained tremendous momentum. The amount of research on mobile recommender systems can reflect the development of a variety of research topics such as mobile computing and context-aware systems. Hence, performing a scientometric mapping on this topic is needed. However, there is a lack of research in this area that aims to perform a detailed scientometric mapping. The objective of this study is to perform a scientometric mapping related to mobile recommender systems. We analysed publications between 2002 and 2017 indexed in Web of Science. The analysis maps the parameters of total output, the growth of output, authorship, major contributors, thematic trends and emerging topics in the field. Our study serves as a resource for future research by shedding light on how trends in mobile recommender systems research have evolved as well as providing insights into the current state of this field.

The Glamorous World: How Instagram Use is related to Affluence Estimates, Materialism, and Self-esteem
by Yoori Hwang, Se-Hoon Jeong
Abstract: Based on cultivation theory, this study examined whether Instagram use is positively related to: 1) greater affluence estimates (i.e., estimates regarding the prevalence of affluence); 2) greater materialistic values, and ultimately; 3) lower self-esteem. Based on an online survey of 530 adults in Korea, this study found that Instagram use was positively related to affluence estimates and materialistic values. In addition, the results showed that Instagram use was indirectly related to lower self-esteem mediated by greater materialistic beliefs. Theoretical and practical implications of these findings are discussed.
Keywords: Instagram; cultivation theory; affluence; materialism; self-esteem.
Use of social networking applications by immigrant children, adolescents, and young adults to maintain contact with those who remained in the country of origin: usage characteristics and habits
by Gila Cohen Zilka
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.

Investigating the adoption intention of gamification apps on mobile services
by Cheng-Kui Huang Tony, Shin-Horng Chen, Ya-Wen Lee
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.

Effects of virtual reality news on knowledge gain and news attitudes
by Se-Hoon Jeong, Sonho Kim, Jung-Yoon Yum, Yoori Hwang
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.

Multimodal systems for speech recognition
by Orken Zh. Mamyrbayev, Keylan Alimhan, Beibut Amirgaliyev, Bagashar Zhumazhanov, Dinara Mussayeva, Farida Gusmanova
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.

A longitudinal study on the effects of motivational mobile application uses on online news engagement
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 (2013-2016) 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.

The adoption of NFC-based mobile payment services: an empirical analysis of Apple Pay in China
by Xiaodie Pu, Felix T.S. Chan, Alain Yee-Loong Chong, Ben Niu
Abstract: With the growing trend of mobile services prevailing in every sphere of our daily life, near field communication (NFC) is at the forefront of transforming the existing payment experience through providing a unified, secure transaction channel which can serve as an alternative to smart cards. Taking the opportunity offered by the recent launch of Apple Pay in China, this research aims to investigate the determinants of the behavioural intention to adopt NFC-enabled mobile payment services. The proposed model extends the technology acceptance model (TAM) with consumer trust, service quality dimensions and prior experience of users. The model is tested using survey collected from 166 iPhone users in China. Perceived usefulness and trust are identified as significant drivers of behavioural intention to use Apple Pay. Among all the service quality dimensions, reliability is identified the most important factor affecting behavioural intention through perceived usefulness, which reflects consumers' emphasis for stable, error-free transaction experience. Structural assurances, calculative-based trust and confidentiality are also shown to have indirect positive influence on behavioural intention through paths on trust. Finally, the mediation effects of perceived usefulness and perceived ease of use are analysed.
