Chapter
The past two decades have witnessed tremendous change in our media ecologies, with one big trend among those changes being the rise of mobile media. Using these devices is not tied to any given location but they can be carried along with their users, enabling media use in nearly each and every context and situation in our everyday lives. Hence, the...

Background Current systematic reviews of randomized controlled trials suggest positive influences of mobile app-based health promotion programs on dietary and physical activity behaviors. However, the actual adoption of and rates of nutrition app use remain low among the overall population. Therefore, we took a step back and investigated actual use...

Full-text available
Over the past three decades our media ecologies have changed substantially, not at least changing the ways in which we get in touch with the news. These changes have led both to high hopes for more equality in news access and a better-informed electorate, as well as fears of news avoidance, filter bubbles, and increasing knowledge gaps, with recent...
Article
We investigated how sharing performance on Facebook and Twitter is influenced both by news articles’ content characteristics and the availability of additional news articles reporting on the same news topic. We conducted a multi-method study, integrating automated data collection and manual/automated content analyses of 1,764 German online news art...
Article
Mobile devices are deeply embedded in people’s everyday lives. On the one hand, this opens up a new field for media and communication research. On the other hand, the widespread diffusion allows for integrating mobile devices into our methodological toolkit. Researchers across the globe have creatively started to take advantage of these new opportu...

Background: To achieve clarity on mobile health's (mHealth's) potential in the diabetes context, it is necessary to understand potential users' needs and expectations, as well as the factors determining their mHealth use. Recently, a few studies have examined the user perspective in the mHealth context, but their explanatory value is constrained b...

Article
Quantifying the ubiquitous, ephemeral, and highly diverse patterns of mobile social media (MSM) use is a challenge for communication research. Most researchers employ retrospective survey measurement, thus depending on the accuracy of users’ memories and generalizations. Alternatively, some researchers rely on in-situ measurement, being less depend...

Chapter
Latent class analysis is a statistical procedure to identify underlying and unobservable categorical latent variables based on categorical observed indicators. By attributing cases to the value of the categorical latent variable it most probably belongs to, latent class analysis can be used for clustering. Latent class analysis does have a series o...

On social network sites (SNS), people are increasingly confronted with news content—even if they have not actively been looking for it. Although it is widely recognized that SNS have become a main driver for such incidental news exposure, we know little about the factors that influence whether users engage with news encountered on SNS. Thus, this s...

The mobile phone appropriation (MPA) scale, originally developed in German, was translated into and adapted to English and initially validated through a confirmatory factory analysis (CFA) in this study. First, the theoretical background of the MPA model is briefly introduced, followed by explanations regarding the process of translating the origin...

Chapter
Die Diffusionstheorie beschäftigt sich mit dem Prozess der Verbreitung von Innovationen in einer Gesellschaft. Sie ist in zweierlei Hinsicht relevant für die Kommunikationswissenschaft: zum einen ist der Diffusionsprozess selbst ein maßgeblich durch massenmediale und interpersonale Kommunikationskanäle angetriebener Prozess, zum anderen stehen oftm...

Abstract This study examines the development of video game enjoyment over time. The results of a longitudinal study (N=62) show that enjoyment increases over several sessions. Moreover, results of a multilevel regression model indicate a causal link between the dependent variable video game enjoyment and the predictor variables exploratory behavior...
Article
The web is going mobile, and the scope of mobile communication is widening tremendously, thus paving the way for a wide array of new forms of mobile device use. However, not every user is necessarily all the time taking advantage of the expanded affordances of mobile devices. Texting and phoning are still the predominant services in mobile communic...

Full-text available
Television and mobile telephone constitute two media technologies that are strongly anchored in most consumers' everyday life. Hence, combining those two seems a promising bet. Not surprisingly, early expectations on the success of mobile TV were extremely confident (European Commission 2008, Abiniak, 2008, Cugnini, 2008). While no reliable data fo...

Full-text available
The evolution of mobile communication devices and services has taken up a dynamic which makes any prognosis on in this field almost impossible. Whereas part of this dynamic may remain inscrutable, we believe that a much higher degree of explanation can be achieved by paying more attention to the process of appropriation. To seize this potential, we...
