With the arrival of the mobile payment era, in addition to facing huge business opportunities and potential interests, business owners are also pondering how to combine their own advantages to maximise the wealth of shareholders, which is an important issue worthy of attention. This study found that there was a significant abnormal return before the event date, suggesting that investors had inconsistent opinions. Positive opinions were mainly towards non-financial industry operators, while negative opinions were mainly towards financial industry operators. This phenomenon may be due to investors holding different expectations for different mobile payment companies.","PeriodicalId":433337,"journal":{"name":"Int. J. Mob.

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.

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.

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

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

The unified theory of acceptance and use of technology 2 (UTAUT2), was used to investigate the influence of various factors on the users' Behavioural intention of use for mobile applications. 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. Due to comparatively simpler design and less decoding complexity orthogonal STBCs are very attractive. 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.

Agriculture is one of such domains where wireless sensor networks are successfully used for the monitoring and protection of agricultural environment. In order to bring out the wild applications of wireless sensor networks in wisdom agriculture, this paper mainly examined the factors affecting user continuous adoption of wireless sensor networks based on extended technology acceptance model (TAM). 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. We found that British m-commerce users, compared to Russians, have significantly higher performance expectations for m-commerce services, especially hedonic services.
