The Big Meaning of Small Messages: The Use of WhatsApp in Intergenerational Family Communication
2018
This study explores the use of WhatsApp instant messenger in extended families in two countries, Finland and Italy, that represent different family and communication cultures. Qualitative research material was collected in 2014/2015 from families consisting of three or more generations and living either in the same or different households. A directed approach to qualitative content analysis was applied in the analysis of the research data. The results of the study show that WhatsApp is considered to facilitate family interaction across generations. The success of WhatsApp in the family context accounts for two main factors: first, for the possibility to reach the whole family at once; and s…
Processes discriminating adaptive and maladaptive Internet use among European adolescents highly engaged online.
2015
Today adolescents are highly engaged online. Contrary to common concern, not all highly engaged adolescents develop maladaptive patterns of internet use. The present qualitative study explored the experiences, patterns and impact of use of 124 adolescents (M(age) = 16.0) reporting signs of internet addictive behaviors. The focus was to discern adaptive and maladaptive use patterns, which promote or interfere with adolescents' development, respectively. Semi-structured individual interviews were conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, Netherlands and Iceland) and qualitatively analyzed using grounded theory. Considerable variability emerged in the way …
When Methodology Interferes With Substance
2005
For campaigners, and also attendant researchers, the advent of the Internet has challenged established ways of doing their respective campaign business. Practitioners, used to running local and media campaigns, can nowadays also resort to elements of web campaigning, while electoral researchers, used to running election studies based on personal or telephone interviews, can now employ online surveys to do their business. However, e-campaigning and online polling suffer from severe deficiencies. Based on online and offline surveys conducted in the run-up to the 2002 German election, we show two things. First, online surveys yield biased results; second, e-campaigning reaches only a tiny fra…

Network Overlap and Network Blurring in Online Social Networks
2016
Online communities and the online social networks embedded become a prominent medium for social interactions. The success of social media depends on usersâ willingness to continue investing their time and efforts in the absence of economic rewards, making psychological attachment critical to online communities. While prior studies identify that members do develop psychological commitment to online communities, why and how the commitment arises remain underexplored. This study focuses on the relationship between network overlap, a common feature of online social networks, and affective commitment to an online community. Drawing on the commitment theory and social network boundary theory, w…
Synchronicity matters: defining the characteristics of digital generations
2015
This paper investigates whether or not the proposition that the second digital generation (or so-called digital natives) is more engaged in social use of the Internet than older generations is tenable. By analysing nationally representative questionnaire-based survey data collected from Finland in 2011 (N = 612), the study shows that rather than social use of the Internet in general, it is the synchronicity of online communication that distinguishes user generations. Results show that, in contrast to asynchronous modes of online communication (e.g. social networking sites, blogs and online discussion forums), synchronous modes (e.g. instant messaging and Internet calls) are clearly generati…
