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.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

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.","PeriodicalId":433337,"journal":{"name":"Int.

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.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

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.","PeriodicalId":433337,"journal":{"name":"Int.

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.

Confidence in the internet operator was used as an external variable for the UTAUT2 model. A surveying methodology was used for the investigation, with a sample of 402 users, which were then analysed using the partial least squares structural equation modelling (PLS-SEM) model. The constructs of UTAUT2, with the exception of price value and facilitating conditions, were all significantly related to the behavioural intention to use mobile applications.

Space-time block codes have been recommended for high diversity gain in MIMO communication systems.

In this paper, we propose a novel adaptive companding method for peak to average power ratio reduction in IEEE 802.16 standards used in 4G wireless mobile communications with orthogonal space time block coded MIMO-OFDM systems. This is obtained by fixing compander parameters independently for statistically unrelated symbols in OFDM waveform and according to the features of input symbols. The bit error rate performance analysis of the proposed system under Rayleigh fading MIMO channel conditions has also been presented. Simulation results showed that the proposed method performs better for a given PAPR preset value and a slight improvement in the BER performance was observed over fixed compander.","PeriodicalId":433337,"journal":{"name":"Int.

Through the employment of structural equation model technology, a continuous adoption model of wireless sensor networks is proposed and assessed based on the statistical data from 256 questionnaires. The results shows that flow experience and user satisfaction have direct influences on the continuous usage of wireless sensor networks. Additionally, social norms and perceived cost, as the critical independent variables, significantly affect flow experience which further has an influence on the continuous usage intention of mobile games. Finally, this study also provides practical suggestions for wireless sensor networks vendors to facilitate the continuous usage of agricultural wireless sensor networks.","PeriodicalId":433337,"journal":{"name":"Int.

We follow the empirical approach of Harris et al. (2005) and update it with new service items in four main m-commerce categories. Our theoretical foundation rests on the GLOBE study and the UTAUT2 acceptance model.
