Effects of Personal Motivation and Computing Characteristics on Ubiquitous Mobile Device Usages
by Changsu Kim, Jongheon Kim, Dan J Kim
Abstract: As we experience the pervasive penetration of mobile computing technology in our daily life, knowing the characteristics of ubiquitous computing (UC) and understanding user motivation has become important for facilitating the usage of mobile devices. Extending previous research on the use of UC by introducing a theory from consumer research and uses and gratifications theory, the study focuses on intrinsic and extrinsic values that the mobile user experiences when possessing, interacting with, and using UC enabled mobile devices. This study makes the broad assumption that UC characteristics and user motivation can be considered as the key characteristics of the adoption of UC devices. It also examines the moderating effects of user types of UC-enabled mobile devices. The results indicate that both personal motivation and UC characteristics had positive effects on the users attitude toward the adoption of UC-enabled mobile devices. Additionally, the perceived utility of mobile devices was directly influenced by UC characteristics.

Predicting Mobile Uses for Big-Event Content: The Role of Active Choice, Habit and Structure
by Tang Tang, Roger Cooper
Abstract: Mobile technologies have substantially changed how people consume media content, in particular during big events. This study examined audiences mobile experience with the first mobile Olympics and found that motivations, preference, perceived usefulness, access to media technologies, and media use routine significantly predicted mobile use for big-event content. Additionally, findings suggest that compared to nonusers, mobile Olympics users were more intensely engaged and involved in sports and the Olympics overall, enjoyed a broader range of Olympics sports, and were more accustomed to using online and mobile sources to view media content. Television was still the dominant platform for big-event viewing, however, mobile consumption increased dramatically during the London Olympics, and indicated a need for more personalised, multifaceted programming with mobility and immediacy.
Keywords: Mobile use; Olympics; Survey; Audience behavior; Technology adoption.
How online social ties and product related factors influence purchasing intention in mobile social commerce context?
by HongQian Wang, Zheng Zhang
Abstract: With the rapid growth of social media platforms and mobile devices, the mobile social commerce changes consumers purchasing behaviour. A theoretical model based on the theory of planned behaviour (TPB) and perceived value theory is developed to investigate the purchasing intention within mobile social commerce context. The stated preference (SP) survey is conducted to collect data through nine hypothetical scenarios generated by the orthogonal configuration of four control factors. We targeted at people with WeChat account and total 1809 observations have been gathered. The results indicate that perceived social tie strength and social influence positively affect the intention to purchase. Furthermore, there exists an inverse U-shaped relationship between perceived usefulness and purchasing intention. The practical model further demonstrates that the purchasing intention is relatively high when perceived usefulness is moderate and the factors of perceived social tie strength, social influence and product price could slightly influence purchasing intention in the condition of low level perceived usefulness.
Keywords: mobile social commerce; purchasing intention: theory of planned behaviour; TPB; perceived value; social tie; perceived usefulness; social influence; experience; stated preference survey; SP survey.
The Determinants of Trust Transfer on Mobile Shopping Decision: Flow Experience as a Moderator
by Hsin Hsin Chang, Kit Hong Wong, Pin Wei Ho
Abstract: This study tended to develop a trust transfer model and examine the effect of trust transference among trust in physical stores, e-service and mobile shopping (m-shopping) service on m-shopping decisions. Characteristics of trustworthiness (ability, integrity and benevolence) were tested as antecedents, and flow experience was adopted as a moderator in the model. 419 valid questionnaires were collected from e-survey. The analytical results indicated that ability, integrity and benevolence increased customer trust in physical stores and e-service, and trust transference existed among different shopping channels; all three types of trust positively influenced m-shopping decision; flow experience significantly moderated the relationship between trust in physical stores and m-shopping decisions. The study suggested that managers should equally value all the shopping channels and improve its e-service quality by providing an aesthetic, secure and usable website, and dedicating their efforts to environmentally-friendly and community activities to show corporate social responsibility (CSR).
Keywords: Trust transfer; trustworthiness; flow experience; mobile shopping.

Mobile Shopper Typology
by Michael Groß
Abstract: Since m-shopping has gained widespread popularity in society, it has become mainstream in many parts of the world. Consumers not only use mobile devices during their entire path-to-purchase in and around the brick-and-mortar business, but they also increasingly make direct internet purchases with their mobile devices. Consequently, one can expect the shopping behaviour of consumers to be diverse. Therefore, based on a typology approach, this study provides a detailed insight into the different buying routines of m-shoppers. Using a sample of 799 consumers, in a first step this study extracts and verifies three m-shopper clusters: while motivated shoppers and casual shoppers are located at the extremes of the cluster profiles, smart shoppers are somewhere in the middle. Then, in a second step, the empirical findings reveal further significant differences between all three m-shopper types in terms of their individual path-to-purchase, thereby confirming diverse consumption patterns where the m-channel is used.
Keywords: Mobile shopping; m-shopping; mobile purchasing; shopping motive; shopper segmentation; consumer typology; path-to-purchase; shopping behaviour; mobile shopper; cluster analysis.
The Impact of Mobile Communication Uses on Civic Engagement: Moderating Effects of Exposure to Politically Diverse and Weak-Tie Networks
by Chang Sup Park, Homero Gil De Zuñiga
Abstract: Based on a nationally representative survey (N = 1,540) of mobile phone users, this study investigates how diverse types of mobile phone use relate to exposure to different political and social views (i.e., crosscutting exposure), attributes of people's discussion network (i.e., weak-tie contacts), and civic engagement. Results indicate that using mobile phones for informational and expressive purposes is closely linked to exposure to diverse viewpoints through mobile communication and engagement in civic affairs. Recreational use of the mobile phone has a statistically significant link to crosscutting exposure. Further, both crosscutting exposure and weak-tie contacts moderate the association between mobile phone use for informational and recreational purposes and civic engagement. In a three-way interaction, crosscutting exposure and weak-tie contacts moderate the relationship between informational mobile phone use and civic engagement.
Keywords: mobile phone; civic engagement; crosscutting exposure; weak ties.

Social Attachment, Life Satisfaction, and SNS Continuance: A Dual-Role Perspective
by Yongqiang Sun, Nan Wang, Xiao-Liang Shen, Liuhan Zhan
Abstract: As the sustainability of social networking sites (SNS for short) heavily relies on the content generated by users, it is important to understand the factors driving users' continuous participation. Considering that SNS has permeated almost every facet of people's lives, this study proposes to understand SNS continuance from the life-oriented perspective beyond the technology-oriented perspective. Further, due to the social nature of SNS, we propose to understand the antecedents of life satisfaction by considering the dual role of social attachment. It is posited to directly enhance individuals' life satisfaction and negatively influence life satisfaction through the mediating effect of envy. An online survey among WeChat Moments users in China was conducted to validate the proposed research model and hypotheses. The data analysis results based on partial least squares approach confirm all the hypotheses.
Keywords: Social networking sites; continuance intention; life satisfaction; social attachment; envy.

Abstract: This paper examines through the lens of expectancy-valence theory the impact of trust, privacy, and security on the decision to use the internet for online shopping and social media. It also investigates the moderating impact of Hofstedes cultural dimensions on the hypothesised relationships. The comparative analysis of 302 surveys from users in the USA and Qatar revealed that trust in internet technology and trust in vendors are the strongest two factors in making decisions to use the internet for online shopping and social media. The results indicated that the cultural dimensions moderated the hypothesised relationships. Surprisingly, Qataris respondents, compared to US respondents, were more influenced by privacy concerns when making decisions to use the internet for online shopping or social media. Implications for researchers and practitioners are reported.
Keywords: trust; security; privacy; social media; online shopping; expectancy-valence theory; Hofstedes cultural dimensions.
Characterizing Mobile-Enhanced Cognitive Abilities: Implications for Accounting Jobs
by Hannah J. Ji, Gavriel Salvendy
Abstract: The purpose of this research paper is to characterise mobile-enhanced cognitive job requirements and analyse implications on accounting jobs for performance improvement and human resource management. This paper first develops a mobile cognitive task analysis (MCTA) model based on the human information processing theory, which identifies the cognitive abilities that can be enhanced by mobile devices when performing cognitive-intensive jobs. Second, these mobile cognitive abilities are decomposed into 52 measurable items and assessed by surveys. Data were collected for 50 cognitive-oriented jobs from 400 surveys with 368 valid surveys (92% of valid survey). Third, results from factor analysis indicate that there are nine dimensions of mobile-enhanced cognitive abilities. Fourth, the mobile-enhanced cognitive ability topographies on three accounting jobs (Accountant, Auditor, and Tax Accountant) were constructed based on the weighted factor score analysis, which indicate that the accounting jobs have different requirements on the derived mobile-enhanced cognitive ability intensities. Finally, theoretical and practical implications are also presented in this paper.

Design alternative evaluation based on Social Utility and Market Share Prediction
by Kyungdoh Kim, Seokcheon Lee, Gavriel Salvendy
Abstract: In new product or service development, design alternatives are generally evaluated by subjective rating, and the one with the highest average score is often chosen. However, the public might not prefer an alternative as much as its average rating suggests. The main objective of this study is to examine the possibility of identifying a predictive function that can accurately represent the products that most people want to purchase in the context of mobile phone products. This paper introduces social welfare functions for developing predictive functions and several metrics to evaluate the functions. Two case studies were performed to determine predictive function for mobile phones. In both case studies, the Atkinson welfare function with a parameter value of 2.5 predicted subjects purchase decisions and market sales the most. The commonly used average function was not as good as the Atkinson function.
Keywords: design evaluation; social utility; mobile phone; predictive function; atkinson function; market share.
Effects of Personal Innovativeness on Mobile Device Adoption by Older Adults in South Korea: The Moderation Effect of Mobile Device Use Experience
by Misook 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.
Keywords: older adult; personal innovativeness; mobile device; technology acceptance model;; mediation effect; moderation effect.
Development of Software Based Vendor Independent WLAN Controller
by Mehmet Ali Ertürk, Muhammed Ali Aydin, Luca Vollero
Abstract: Wireless hotspots have become popular, due to their ability to provide inexpensive and easy-to-deploy network infrastructures. Controlling and maintaining large-scale wireless infrastructures with traditional methods is complex and error-prone. Hence, it is necessary to use centralised solutions to handle configuration, monitoring and management functions in large-scale wireless hotspots. Existing solutions solve these problems within their hardware ecosystems and are constrained by vendor being depended on hardware and software restrictions. In this study, we propose and evaluate a wireless local area network (WLAN) access point (AP) controller built on top of a standard WLAN management protocol and free of any particular hardware and software restrictions. The proposed WLAN controller is a software component based on the control and provisioning of wireless access points (CAPWAPs) protocol. The proposed controller is evaluated by means of a TestBed including a variety of WiFi devices from different vendors to solve a QoS-LB problem.
Keywords: Wireless LAN Controller ; Access Controller ; CAPWAP ; QoS IEEE 802.11.
From text messages to WhatsApp: cultural effects on m-commerce service adoption in the UK and Russia
by Julian Bühler, Markus Bick
Abstract: Smartphone's and other mobile devices are omnipresent in many people's daily lives. Penetration of mobile devices has caused a significant increase in m-commerce usage, leading to both new opportunities and new challenges for providers. In this cross-cultural study, we investigate Smartphone usage of people from Russia and the UK to identify differences regarding the adoption of 14 prominent m-commerce services. 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. Social surroundings play a minor role in both countries during the decision-making process.

Novel routing mechanism for IoT based emergency rescue scenarios
by RASHMI CHAUDHRY, Shashikala Tapaswi
Abstract: Routing in emergency rescue scenarios where nodes around the site are mobile and send the information about the service needs to the concerned service providers through internet connectivity is an important issue. Focus is done by researchers in the respective fields for vehicular ad hoc networks (VANETs) and wireless sensor networks (WSNs) but the scenarios having mobile nodes around the site and having IoT environment have not been addressed. As this type of case includes time constraint-based services, thus a new mechanism predicting mobility of nodes at gateway and multicasting of the required information accordingly, is proposed in this paper. Meta-heuristic-based algorithm, grasshopper optimisation algorithm (GOA) is modified to fit for the prediction and then applied for taking decision related to multicast routing named as grasshopper-based routing and mobility (GRAM) algorithm. This prediction helps the network to send updates to the emergency site with minimal cost and energy consumption. Analysis of results shows the improved performance of the proposed mechanism in terms of both speed and accuracy.
Keywords: Emergency management; routing; Meta-heuristics algorithm; Mobility Prediction.
Performance of an Adaptive Compander in Wireless Mobile Communication Systems
by Beena A. O, Sakuntala S. Pillai
Abstract: The most popular technique used for high data rate services in 4G scenario is MIMO-OFDM. 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.

An Empirical Examination of Adoption of Mobile Applications in Spain and Portugal, based in UTAUT
by Jose Ramon Saura, Marisol B. Correia, Pedro R. Palos-Sanchez
Abstract: The purpose of this study is to improve understanding of the apps (mobile applications) market in Spain and Portugal, which are countries that have many more Smartphone's per inhabitant than any other European country. 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. Habits and social influence are found to be the factors that most affect behavioural intention. The results obtained allow a better understanding of the users' needs when considering their intention to download and use apps.
Keywords: App; mobile application; acceptance model; trust; social influence; hedonic motivation; effort expectancy; habit; the unified theory of use and acceptance of technology; UTAUT2; m-commerce.

Multi-view Video CODEC Using Compressive Sensing for Wireless Video Sensor Networks
by Angayarkanni Veeraputhiran, 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; CS; DVC; Frame approximation; Wireless Video Sensor Networks.
Behavioral Clustering of the Cell Phone Users in Various Country Markets
by Matti Haverila, Kai Haverila
Abstract: Acknowledging Aoki and Downes (2003) cell phone behaviours, the significance of social ecological models and behavioural clustering, the existence of inter-market behavioural clusters in Finland, UAE, China, Canada and New Zealand were investigated. There were significant differences in the cell phone behaviours between the different age groups (in 19 out of 30 variables), genders (20/30) and different countries of residence (30/30) implying that these variables could be used as distinguishing variables regarding the existence of the cell phone behavioural clusters. This implies that the variables age, gender and country of residence do not efficiently discriminate the sample population in terms of the cell phone behaviour. Finally, the behavioural variables were used as the cluster variate in order to discover more viable cluster (segments) in the data set. The paper concludes with a discussion regarding the academic and managerial implications.

by Cetin Kalburan, Selcuk Burak Hasiloglu, Ahmet Bardakci
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; response categories; mobile phone sector.
An integrated model of the antecedents and consequences of perceived information overload using WeChat as an example
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 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.
Keywords: Offline mobile payment;Mobile commerce;Technology acceptance model;User acceptance.
Customer Resistance to Churn in a Mature Mobile Telecommunications Market
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
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.

UNDERSTANDING THE FACTORS AFFECTING CONSUMERS CONTINUANCE INTENTION IN MOBILE SHOPPING: THE CASE OF PRIVATE SHOPPING CLUBS
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.
Keywords: Mobile shopping; Private shopping clubs; Expectation confirmation model; Flow theory; Trust.

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.

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.
Keywords: Keywords: virtual reality (VR); news; journalism; knowledge; attitudes.
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
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.
Keywords: Internet communication applications; social networking; WhatsApp; social development; immigrants.
What customers want from smart devices: Investigating explicitly judged and implicitly derived success factors
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.
Keywords: smart device; product success; success factor; competitive advantage; innovativeness.
What drives students online self-disclosure behavior on social media? A hybrid SEM and artificial intelligence approach
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.
