Measuring mobile phone use: Self‐report versus log data.

Approximately 40% of mobile phone use studies published in scholarly communication journals base their findings on self-report data about how frequently respondents use their mobile phones. Using a subset of a larger representative sample we examine the validity of this type of self-report data by comparing it to server log data. The self-report data correlate only moderately with the server log data, indicating low criterion validity. The categorical self-report measure asking respondents to estimate “how often” they use their mobile phones fared better than the continuous self-report measure asking them to estimate their mobile phone activity “yesterday.” A multivariate exploratory analysis further suggests that it may be difficult to identify under- and overreporting using demographic variables alone.

CHILDREN, YOUTH, AND MOBILE COMMUNICATION

Teens are, perhaps the most consummate mobile telephone users. Teens have made text messaging into a common form of interaction. They have learned how to coordinate and indeed micro-coordinate interaction via the mobile telephone. They use the camera to share photos of enticing members of the opposite sex and to gather peer opinion on the color of potential clothes purchases. The mobile phone is a safety link, it allows for effective coordination, it is an object lesson in the use of money for teens and often, it is a reluctantly accepted umbilical cord to their parents and a central artifact of their self-image (Fortunati, 2001). At the same time the device has resulted in school bans, a new form of bullying and has opened a new front in the war against cheating during exams (May & Hearn, 2005). There are reports of mobile phone addiction in Korea (Park, 2003) and the extended use of mobile communication can impact on adolescents sleep (Van den Bulck, 2003) When thinking of teens however, there are additional issues that are stirring. In many cases, the mobile telephone has become a tool in their emancipation from their home. This means that on the one hand it gives the child a source of interaction that is not mediated by parents – as is the case with the traditional landline telephone – and it also plays into the social cohesion of the peer group (Ling, 2004, , 2006; Ling & Yttri, 2002).

Texting as a life phase medium

SMS has grown to be a common form of interaction in Norwegian society. Its adoption started among teens but has since been taken into use by other age groups. However, the use patterns for teens seem to be different from those of older users. This paper examines the assertion that SMS is a life phase and not a cohort phenomenon. That is, its use is more intense among teens and more moderate among older age groups. Data for the analysis comes from a series of six nation-wide surveys of Norwegians over the age of 13. Questions on the reported use of SMS were included in all these surveys. This information was adjusted in order to remove the effects of generally increased use over time. The analysis shows that the proportion of text messages sent by different age groups stays rather stable over time. Indeed there seems to be a type of ‘‘standing wave’’ of use associated with older teens and those in their early 20s. While there are cohort effects visible in the data, the analysis indicates that texting is largely a life phase phenomenon. If the curve had flattened out with time it would have indicated that the teens are carrying texting with them as they grow older. This, it seems is not the case. The overall use of SMS has increased in Norwegian society but the relative distribution of the text messages has remained centered around those in their late teens. This seems to indicate that the intense use of SMS is a life-phase phenomenon.

Mobile communication in the global south

Mobile communication has become a common phenomenon in most parts of the world. There are indeed more mobile subscriptions than there are people who use the internet. For many people outside of the metropolitan areas of Europe and North America, this is literally their first use of electronically mediated interaction. This preface to the special issue of New Media & Society examines mobile communication in a global context. Through an overview of eight articles situated in the global south, we describe how mobile communication sheds light upon notions of information, appropriation and development and how it is challenging, and in many cases changing, notions of gender. While the mobile phone reshapes development and micro dynamics of gendered interactions, it is not necessarily a revolutionary tool. Existing power structures may be rearranged, but they are nonetheless quite stable. The analysis of mobile communication in the global south helps us to understand the rise of innovative practices around information and communication technologies and, in turn, enables us to develop theory to understand these emergent empirical realities.

The socio-demographics of texting: An analysis of traffic data

Who texts, and with whom do they text? This article examines the use of texting using metered traffic data from a large dataset (nearly 400 million anonymous text messages). We ask: 1) How much do different age groups use mobile phone based texting (SMS)? 2) How wide is the circle of texting partners for different age groups? 3) To what degree are texting relationships characterized by age and gender homophily? We find that texting is hugely popular among teens compared to other age groups. Further, the number of persons with whom people text is quite small. About half of all text messages go to only five other persons. Finally, we find that there is pronounced homophily in terms of age and gender in texting relationships. These findings support previous claims that texting is an important element of teen culture and is an element in the construction of a bounded solidarity.

Mobile Phones Bridging the Digital Divide for Teens in the US

In 2009, just 27% of American teens with mobile phones reported using their devices to access the internet. However, teens from lower income families and minority teens were significantly more likely to use their phones to go online. Together, these surprising trends suggest a potential narrowing of the digital divide, offering internet access to those without other means of going online. This is an important move, as, in today’s society, internet access is central to active citizenship in general and teen citizenship in particular. Yet the cost of this move toward equal access is absorbed by those who can least afford it: Teenagers from low income households. Using survey and focus group data from a national study of “Teens and Mobile Phone Use” (released by Pew and the University of Michigan in 2010), this article helps identify and explain this and other emergent trends for teen use (as well as non-use) of the internet through mobile phones.

Mobile communication and political participation in South Korea: Examining the intersections between informational and relational uses

This study aims to extend the literature on mobile communication by demonstrating that multifaceted mobile practices work in coordination with one another to predict enhanced engagement in public life. Using a national survey of adults in South Korea, we show that informational mobile phone use to gather and discuss content about news and public affairs is positively associated with political participation while the corresponding link for relational mobile phone use to enhance strong personal tie relationships being also significant. More importantly, the findings indicate that the two mobile usage patterns interact with each other to explain increased involvement in political activities. However, analysis of the three-way interaction points to a noteworthy caveat, namely that those who are already engaged, by virtue of their perceived capacity to produce desired outcomes in politics (i.e., self-efficacy), are even more likely to obtain motivational benefits from the manifold uses of mobile telephony.

Small Circles: Mobile Telephony and the Cultivation of the Private Sphere

This article examines how we use mobile telephony to maintain our physically and socially closest social circle. The analysis is based on traffic data gathered from Norway using approximately 24 million calls and texts made by private individuals. Previous research has shown that our temporal and spatial movement is highly predictable and that the majority of calls and text messages are sent to only four to six different persons. This article extends this research by examining both tie strength and the distance between the interlocutors in urban and rural settings. The findings show that even as information and communication technologies (ICTs) potentially put the world at our fingertips, the mobile phone is an instrument of a more limited geographical and social sphere. Approximately two-thirds of our calls/texts go to strong ties that are within a 25-km radius.

Product Adoption Networks and Their Growth in a Large Mobile Phone Network

To understand the diffusive spreading of a product in a telecom network, whether the product is a service, handset, or subscription, it can be very useful to study the structure of the underlying social network. By combining mobile traffic data and product adoption history from one of Telenor’s markets, we can define and measure an adoption network—roughly, the social network of adopters. By studying the time evolution of adoption networks, we can observe how different products diffuses through the network, and measure potential social influence. This paper presents an empirical and comparative study of three adoption networks evolving over time in a large telecom network. We believe that the strongest spreading of adoption takes place in the dense core of the underlying network, and gives rise to a dominant largest connected component (LCC) in the adoption network, which we call “the social network monster”. We believe that the size of the monster is a good indicator for whether or not a product is taking off. We show that the evolution of the LCC, and the size distribution of the other components, vary strongly with different products. The products studied in this article illustrate three distinct cases: that the social network monsters can grow or break down over time, or fail to occur at all. Some of the reasons a product takes off are intrinsic to the product; there are also aspects of the broader social context that can play in. Tentative explanations are offered for these phenomena. Also, we present two statistical tests which give an indication of the strength of the spreading over the social network. We find evidence that the spreading is dependent on the underlying social network, in particular for the early adopters.

Durkheim and Weber on the social implications of new information and communication technologies

Max Weber and Emile Durkheim made an important contribution to our understanding of new information and communication technologies (ICTs). While they did not discuss ICTs in their work, they provided conceptual tools at the macro-, meso- and micro-social levels that help us understand the use of ICTs. We examine how Weber’s iron cage and Durkheim’s mechanical solidarity and ritual present a coherent account of how ICTs sustain cohesion and also enmesh us in mediated interactions in complex societies. Thus, they directly address the question of the implications of increasingly mediated relationships, which is overlooked by theories that focus only on the relation between individuals and technology. Unlike other theorists who do focus on the societal level, Weber and Durkheim are more concerned with their routine workings, providing a more grounded, everyday, and in this sense realistic understanding of ICTs and social change.
