Tele‐Cocooning: Mobile Texting and Social Scope

The present study examines the tele‐cocooning hypothesis in the context of general trust using a nationally representative survey of Japanese youth. We find that although frequency of texting is positively correlated with general trust, this correlation is spuriously caused by how heavy mobile texters interpret the words “most people” in the general trust measurement. Heavy users assume that “most people” only refers to friends, family, and others going to the same school. When the effect of the “most people” assumption is controlled, the positive association between texting and general trust disappears. Further exploration of the data shows that heavy texting nevertheless has negative implications for social tolerance and social caution, both of which are theoretically proximate to general trust.     

Mobile Geotagging: Reexamining Our Interactions with Urban Space

Mobile geotagging services offer people new ways to interact with and through urban space. In this paper, we focus on a mobile geotagging service called Socialight and the social practices associated with it. In‐depth interviews and participant observation were conducted in order to explore how Socialight's virtual “sticky notes” were used in everyday life. Findings indicated how users communicate about place to help build social familiarity with urban places and communicate through place to allow users to create place‐based narratives and engage in identity management. Such findings deepen our understanding of the social production of space and have implications for future location‐based mobile services.

Unfolding the privacy paradox among mobile social commerce users: a multi-mediation approach

Considering that privacy paradox is currently an underexplored research area, this study proposes a privacy paradox model to explain the reasons behind such phenomenon. Built upon the theoretical link of belief-intention-behaviour and the idea of multi-mediation, this study seeks to discover the relationship between concern for social media information privacy and usage intention, and the potential mediators that stand between such linkage. The results suggest that perceived mobility and social support do mediate the said linkage, and the model could reasonably explain usage intention, which surprisingly has a negative association with usage behaviour. Theoretical and practical implications are subsequently offered.

Discovering Typed Communities in Mobile Social Networks

Mobile social networks,which consist of mobile users who communicate with each other using cell phones,are reflections of people’s interactions in social lives.Discovering typed communities(e.g.,family communities or corporate communities) in mobile social networks is a very promising problem.For example,it can help mobile operators to determine the target users for precision marketing.In this paper we propose discovering typed communities in mobile social networks by utilizing the labels of relationships between users.We use the user logs stored by mobile operators,including communication and user movement records,to collectively label all the relationships in a network,by employing an undirected probabilistic graphical model,i.e.,conditional random fields.Then we use two methods to discover typed communities based on the results of relationship labeling:one is simply retaining or cutting relationships according to their labels,and the other is using sophisticated weighted community detection algorithms.The experimental results show that our proposed framework performs well in terms of the accuracy of typed community detection in mobile social networks.     

移动环境下基于用户轨迹的社交亲近度研究

提出了一种基于时空轨迹的社交亲近度模型,目的是为了解决新一代广播电视服务系统中移动手机电视用户之间控制内容分享问题。该模型首先将用户轨迹空间离散化,并将用户轨迹映射到该离散空间。然后根据相同时刻,用户之间的空间距离,计算用户之间的社交亲近度。根据亲近度,将其朋友分组,以控制分享内容。实验结果表明,该方法能够有效反映用户地理位置轨迹与用户之间的社交关系,平均分组正确率达89%。

E-learning in a low-status female profession: the role of motivation, anxiety and social support in the learning divide

Abstract   The literature seems to suggest that women may be at risk from being excluded from adult education programmes, which use e-learning, especially when they have low economic status. Based on a survey of 551 women, family day care providers, we conclude that there is a persistent divide in PC access and use, as well as in perceived PC skills according to age. Yet, this divide seems to run less along traditional lines, suggesting that personal factors play a more important role. Motivation and anxiety are two related but distinct personal factors that influence computer use and skills in this population. We also found that these factors are mediated by the family context: motivation is higher when (young) children are present in the family. Moreover, children may represent an important form of social support for women not yet using computers. This study concludes that the concerns about the gender gap in computer use may benefit from taking the scaffolding possibilities of the family into consideration and that there may be a case for growing optimism in the use of information and communication technology for adult learning in specific, gender-segregated professions with low status.     

Online arbitration in the social network world; mobile justice on iPhones

Social networks are increasingly becoming important due to many aspects of everyday life supported and being facilitated through on-line activity. Billions of individuals are enjoying the use of social networks today and, therefore, they are becoming an important innovation in the modern world. However, due to disputes and concerns that are associated with such activities, the social networking world has yet to reach its full potential. When disputes occur in the on-line world, measures need be taken to settle those disputes in the same way that they were created. Through solving these disputes, the social networking world will be assisted in reaching full potential. One way of settling user disputes in the social networking world is the use of online arbitration. There are a number of advantages to using online arbitration as the parties involved will only communicate through the Internet and do not need to travel throughout the process. This helps in lowering the litigation costs to all parties involved. Considering the advantages online, arbitration has and the power that the social networking world bares, it is possible for users' disputes to be resolved and encourage communication between masses of users to build their confidence. With confidence that their disputes can be resolved easily, more users will be willing to publicise their profile for other users to view.

Group-Based Mobile Messaging in Support of the Social Side of Leisure

Communication on mobile devices plays an important role in people’s use of technology for leisure, but to date this communication has largely been one-to-one. Mobile internet connectivity can support a variety of group-based messaging and media sharing scenarios. Switching to group-based messaging should enhance the social and leisure aspects of the communication, but in what ways and to what extent? An experimental system for text and photo messaging on mobile devices was tested in a research deployment to four groups of 6–8 participants who used both a group-based and one-to-one version of the system. Results highlight a significant increase in message sending, in mobile device “fun”, and in the social qualities of mobile communication when messaging group-wide, along with a few minor costs. Qualitative feedback provides further explanation of the social benefits.     

The Digital Divide Objectified in the Design: Use of the Mobile Telephone by Underprivileged Youth in Sri Lanka

Most discussions on the digital divide have predominantly focused on social disparities in the physical accessibility of information and communication technologies (ICT), and the proposed solutions are related to providing low cost access to the underprivileged. The mobile phone has been considered as a good solution due to its relatively low cost. This paper, based on an empirical study in Sri Lanka, demonstrates that even though the underprivileged population has adopted the mobile phone, most of the computer based communication facilities available in the phones are ‘inaccessible’ to such users due the objectification of broader social inequalities in the design of phones. In other words, the digital divide is objectified in the design.
