Open source projects leverage a large number of people to review products and improve code quality. Differences among participants are inevitable and important to this collaborative review process—participants with different expertise, experience, resources, and values approach the problems differently, increasing the likelihood of finding more bug...

Timebanking is a service-based community currency, built on the principle that everyone's time is valued equally. It has potential for community building and reenergizing neighborhoods, but it faces several adoption challenges. We report on the largest investigation of timebanking practices to date by analyzing a combination of service exchange rec...

The emergence of social media has had a significant impact on how people communicate and socialize. Teens use social media to make and maintain social connections with friends and build their reputation. However, the way of analyzing the characteristics of teens in social media has mostly relied on ethnographic accounts or quantitative analyses wit...

Wearable activity trackers are becoming widely adopted, yet challenges continue to exist in effective long-­term use and adoption. Existing research focuses mostly on the use and adoption challenges associated with technical-­ or device-­related issues and respective workaround strategies. Little is known about how personal preferences and other in...

Massive Open Online Courses (MOOCs) have recently experienced rapid development and garnered significant attention from various populations. Despite the wide recognition of MOOCs as an important opportunity within educational practices, there are still many questions as to how we might satisfy students' needs, as evidenced by very high dropout rate...

The Massive Open Online Course (MOOC) paradigm has developed rapidly and achieved significant attention from a broad range of populations. However, many people who enroll in MOOCs do not have successful learning experiences. For example, some studies suggest that the relatively weak feelings of community and meager opportunities for collaboration m...

Social media platforms such as Twitter and Facebook are commonly used to disseminate up-to-date news information, but they also contain a lot of noise and irrelevant content. The contents of social media platforms are typically filtered by followship or friendship oriented relationships, and is almost always driven by trending news topics at the na...

A prominent issue in community informatics is community awareness: The awareness of community members of activity in their community. Community awareness helps community members understand and appreciate their community, motivates them to participate and reciprocate, and evokes feelings of empathy, intimacy and solidarity. In this chapter we analyz...

Being aware of local community information is critical to maintaining civic engagement and participation. The use of online news and microblog content to create and disseminate community information has long been studied. However, interactions in the online spaces dedicated to local communities tend to only garner very limited usage, and people oft...

Social media platforms such as Twitter and Facebook are commonly used to disseminate up-to-date news information, but they also contain a lot of noise and irrelevant content.

Dialectical constructivism considers that the source of knowledge comes from constant and complex interactions between the evolving individual and the developing environment (Moshman, 1982). Dialectical constructivism informs dialectical learning pedagogy, where students constantly interact with each other in developing and refining arguments over...

The automatic extraction of metadata and other information from scholarly documents is a common task in aca- demic digital libraries, search engines, and document manage- ment systems to allow for the management and categorization of documents and for search to take place. A Web-accessible API can simplify this extraction by providing a single poin...

The emergence of social media provides an additional channel for broadcasting information to the public and support two-way communication between governmental stakeholders and the public during crisis. Research has focused on large-scale events, and few have investigated how social media can contribute to civic awareness and participation of small-...

Commercial peer-to-peer service exchange businesses, such as AirBnB, Lyft and TaskRabbit, are expanding rapidly, but their non-profit counterparts are lagging behind. We conducted a field study of the most prominent of these, timebanking; a system in which 'time dollars' are earned and spent by people providing services for and receiving them from...

One goal of local communities is to create and reinforce community identity by connecting residents to their local heritage. Technologies have enabled and facilitated the creation and consumption of digitized history content provided by official history institutions as well as individuals. Although much research has been conducted to understand tec...

GitHub provides various social features for developers to collaborate with others. Those features are important for developers to coordinate their work (Dabbish et al., 2012; Marlow et al., 2013). We hypothesized that the social system of GitHub users was bound by system interactions such that contributing to similar code repositories would lead to...

We introduce our ongoing work in community networks and present a system that aggregates geographical community news and events information from local news and social media. Our goal is to present community information according to its content and to make it more visible to local residents, thereby increasing community awareness. We also present a...

Previous research has shown that diversity within distributed collaborative teams can lead to innovation, but trust must exist for the open expression of innovative ideas and establishment of idea credibility. Initial trust is pivotal for distributed teams where team members have never met face-to-face and have only a very limited time to accomplis...

Wiki-like or crowdsourcing models of collaboration can provide a number of benefits to academic work. These techniques may engage expertise from different disciplines, and potentially increase productivity. This paper presents a model of massively distributed collaborative authorship of academic papers. This model, developed by a collective of thir...

Geographically distributed work has become a popular way to work. Past CSCW research has shown that remote workers rely on innovative communication platforms but still face challenges being remote. Research has also provided organizational and managerial strategies to bridge the distance gap. Our study in contrast investigates how individuals devel...

Group brainstorming is widely adopted as a design method in the domain of software development. However, existing brainstorming literature has consistently proven group brainstorming to be ineffective under the controlled laboratory settings. Yet, electronic brainstorming systems informed by the results of these prior laboratory studies have failed...

The latest in the most popular head-to-head fighting video series, Super Street Fighter IV by Capcom, now features spectating functionality. Coupled with audio chat, players can both watch and participate in matches with anyone in the world. We describe a video analysis of over 36 hours of gameplay in SSF4. Our results show that players can deftly...

Personal health records (PHR) have enormous potential to improve both documentation of health information and patient care. The adoption of these systems, however, has been relatively slow. In this work, we used a multi-method approach to evaluate PHR systems. We interviewed potential end users---clinicians and patients---and conducted evaluations...

A computer implemented method, apparatus, and computer usable program code for sampling call stack information. Responsive to identifying an interrupt, a determination is made as to whether all processors in a plurality of processors have generated the interrupt. A determination is made as whether to sample the call stack information based on a pol...

Idea Generation has been a topic of creativity research for centuries. A wealth of creative processes has been devised to overcome difficulties at the perceptual, emotional, and cultural levels. Brainstorming in particular has grown to become synonymous with idea generation. This paper discusses our preliminary study on current conception of brains...

Collaborative brainstorming can be a challenging but important part of creative group problem solving. Mind-mapping has the potential to enhance the brainstorming process but has its own challenges when used in a group. We introduce GroupMind, a collaborative mind-mapping tool that addresses these challenges and opens new opportunities for creative...
