Mobile phone use among Ukrainian and US students: a library perspective
PurposeThis study aims to determine college/university students’ mobile phone practices to understand key user preferences and set a baseline understanding for the development of prospective library informational mobile services.Design/methodology/approachThis study is based on the results of an online-survey method. The authors recruited students majoring in the Information Science program in School of Information at Pratt Institute (USA) (74 participants) and in Kyiv National University of Cultural and Arts (Ukraine) (89 participants).FindingsThe general trends in the use of mobile technologies by American and Ukrainian students were identified. Key components of library mobile services are offered. Such services may include information and reference service via messengers; development of library mobile applications of audio and video content; access to educational, scientific, popular science literature and fiction; and supplementing online services with library chatbots.Research limitations/implicationsThis study was limited to only students majoring in information science at university; however, the data obtained helps outline several general trends common to student youth who are actively working with information.Practical implicationsThe obtained results will be useful in the practical activities of libraries and other information institutions for the development of a comprehensive information service based on mobile technology.Originality/valueThis study contributes to understanding how to improve library informational service considering users habits and preferences. Libraries management and librarians can use the findings as a basis for prioritizing the improvement of library informational mobile service.

ON THE CHALLENGE OF SERVICE RECOMMENDATION TO MOBILE USERS IN SMART CITIES: CONTEXT AND ARCHITECTURE
The industrial and academic interest of the research on mobile service recommendation systems based on a wide range of potential applications has significantly increased, owing to the rapid progress of mobile technologies. These systems aim to recommend the right product, service or information to the right mobile users at anytime and anywhere. In smart cities, recommending such services becomes more interesting but also more challenging due to the wide range of information that can be obtained on the user and his surrounding. This quantity and variety of information create problems in terms of processing as well as the problem of choosing the right information to use to offer services. We consider that to provide personalized mobile services in a smart city and know which information is relevant for the recommendation process, identifying and understanding the context of the mobile user is the key.This paper aims to address the issue of recommending personalized mobile services in smart cities by considering two steps: defining the context of the mobile user and designing an architecture of a system that can collect and process context data. Firstly, we propose an UML-based context model to show the contextual parameters to consider in recommending mobile services in a smart city. The model is based on three main classes from which others are divided: the user, his device and the environment. Secondly, we describe a general architecture based on the proposed context model for the collection and processing of context data.

Exploring UTAUT Model in Mobile 4.5G Service: Moderating Social–Economic Effects of Gender and Awareness
The current study aims to examine how students’ intentions to use 4.5G mobile phones are affected by the social-economic factors of performance expectancy, cost, effort expectancy, and social influence. This study is based on the perspectives of the unified theory of acceptance and use of technology (UTAUT). The central assumption of this study is that when students use 4.5G mobile services to source information at university, their academic performance is likely to improve. From eight private and public universities in Malaysia, 2117 students were enrolled in this study. We investigated the effects of gender and awareness as moderators on the relationships among the variables of interest. The findings showed that social influence and performance expectancy positively affected university students’ intentions to use 4.5G mobile phones. The researchers conducted a multigroup analysis to confirm the moderating effect of gender among the underlying relationships in the model. Structural equation modeling analysis indicated that, unlike awareness, gender did not moderate social influence, effort expectancy, performance expectancy, or the cost of students’ intentions to use 4.5G mobile phones. The implications of the proposed approach, considering the digital transformation concept, could be a topic for future research.

Bringing E-money to the poor : successes and failures
Moving toward universal access to financial services is within reach, thanks to new technologies, transformative business models, and ambitious reforms. Instruments such as e-money accounts and mobile accounts, along with debit cards and low-cost traditional bank accounts, can significantly increase financial access for those who are excluded. This publication examines the lessons of success from four country case studies of Kenya, South Africa, Sri Lanka, and Thailand, that leapt from limitation to innovation by successfully enabling the deployment of e-money technology. These countries have thereby transformed the landscape of financial access to their poor. In addition, two country case studies (Maldives and the Philippines) yield lessons learned from constraints that stalled e-money deployments. Because technology is not a silver bullet, the case studies also explore other strategic elements that need to be in place for a country to expand access to financial services through digital technology.

Network Investment as Drivers of Mobile Subscription – A Firm-level Analysis
Globally, Mobile Network Operators (MNOs) incur considerable capital investments towards the acquisition of spectrum, deployment of mobile networks, and marketing and advertising of their mobile services to potential mobile subscribers. The extant literature, which is mainly conceptual, suggests that such capital investments impact the individual mobile subscriber base of MNOs. However, the extant literature lacks in quantitative explanation of such impacts. We address this lacuna by proposing an empirical framework using a novel panel dataset of the four largest MNOs of India, during the years 2009–2017. We find that capital investments in the spectrum (both contemporaneous and lagged) and mobile networks (lagged) positively impact the mobile subscriber base of MNOs in India. We observe that a “triggering effect,” such as the market rollout of 4G (fourth generation) services, leads to an initial slump in the mobile subscriber base of MNOs, which is counterintuitive and signifies the importance of early network-preparedness on the part of MNOs. We also find that, in the event of the aforementioned market triggers, MNOs’ firm-size and potential to invest in the spectrum, in addition to network-preparedness, are crucial for its survival.

Usability study of the mobile library App: an example from Chongqing University
Purpose
– The purpose of this paper is to determine the usability of the mobile library App of Chongqing University and to provide recommendations for improving the experience of App users.
Design/methodology/approach
– Usability testing, which comprised pre-test questionnaires, accomplishing tasks, and post-test surveys, was conducted in this study. The effectiveness and efficiency of the App, as well as user satisfaction with it, were measured.
Findings
– The mobile App was proven effective but the efficiency of the App required improvement. With regard to user satisfaction, the factors “clarity” and “usefulness” received the lowest and highest scores, respectively. The descriptions of mobile services were unclear and confused users; nonetheless, the services provided by this App were appealing and useful to the users. Based on the measured user experience, this study proposed several recommendations for enhancing the usability of the App.
Originality/value
– An increasing number of domestic and foreign libraries have begun to use mobile Apps to provide new services to patrons. In the future, smartphones are likely to become crucial to the delivery of information services. Given the extensive use of the Super Star Mobile Library system adopted by Chongqing University Library in China, the usability of such a system must be investigated. Improving the usability of the mobile library App can help enhance user experience.
