A large-scale deployment-based research study that logged detailed application usage information from over 4,100 users of Android-powered mobile devices is described, which finds that despite the variety of apps available, communication applications are almost always the first used upon a device's waking from sleep.
Tweets from Justin Bieber's heart: the dynamics of the location field in user profiles
The first in-depth study of user behavior with regard to the location field in Twitter user profiles found that a user's country and state can in fact be determined easily with decent accuracy, indicating that users implicitly reveal location information, with or without realizing it.

This work analyzes the variance in interpretation of the emoji, quantifying which emoji are most (and least) likely to be misinterpreted, and finds significant potential for miscommunication.
The tower of Babel meets web 2.0: user-generated content and its applications in a multilingual context
This study explores language's fragmenting effect on user-generated content by examining the diversity of knowledge representations across 25 different Wikipedia language editions and demonstrates that the diversity present is greater than has been presumed in the literature and has a significant influence on applications that use Wikipedia as a source of world knowledge.
A Tale of Cities: Urban Biases in Volunteered Geographic Information
It is argued that Foursquare has fundamentally failed to appeal to rural populations because VGI is a subset of user-generated content (UGC) and the results suggest that urban biases might exist in non-geographically referenced UGC as well.
The Success and Failure of Quality Improvement Projects in Peer Production Communities
This paper examines the efficacy of a range of targeted strategies to increase the quality of under-attended content areas in peer production communities and shows that certain types of strategies have better quality outcomes than others.
The Geography of Pokémon GO: Beneficial and Problematic Effects on Places and Movement
Focusing on the key geographic themes of places and movement, this paper finds that the design of Pokémon GO reinforces existing geographically-linked biases, and that the game may have instigated a relatively rare large-scale shift in global human mobility patterns.
Avoiding the South Side and the Suburbs: The Geography of Mobile Crowdsourcing Markets
The results suggest that low-SES areas are currently less able to take advantage of the benefits of mobile crowdsourcing markets, as well as for "sharing economy" phenomena like UberX, which have many properties in common with mobile crowdsourced markets.
Measuring self-focus bias in community-maintained knowledge repositories
Two methods to quantify self- focus are outlined, one of which is very computationally inexpensive, and empirical evidence for the existence of self-focus is presented using a "hyperlingual" approach that examines 15 different language editions of Wikipedia.

A study of Omnipedia that characterizes how people interact with information using a multilingual lens found that users actively sought information exclusive to unfamiliar language editions and strategically compared how language editions defined concepts.
