In order to scale innovations in education, a Networked Improvement Community (NIC), forms a network of members with diverse expertise from a variety of contexts. By testing innovations in diverse settings and coordinating what is learned from the tests,...

My doctoral research is an exploratory project focused on understanding and theorizing on the ways in which various social networking technologies (SNTs) facilitate informal knowledge sharing in the workplace. Forms of SNT include (but are not limited ...

This research examines large-scale human interaction occurring through social media during times of mass disruption, seeking to understand how the connected crowd acts to organize a flood of data moving through those platforms into useful information ...

Although the Web enables large-scale collaboration, its potential to support group decision-making has not been fully exploited. My research aims to analyze, extract, and represent disagreement in purposeful social web conversations. This supports ...

The goal of my research is to evaluate how distributed virtual teams are able to use socio-technical systems like Wikipedia to self-organize and respond to complex tasks. I examine the roles Wikipedians adopt to synthesize content about breaking news ...

This extended abstract presents a prototype evaluation of an innovative application called PresenceScape. This application is targeting distributed teams of knowledge workers to support social awareness and informal communication by means of a ...

The focus of this study is a group blog site of special librarians who work at the library department in a large geographically dispersed corporation. We examined the field data through the framework of "history in person" in order to understand the ...

In this paper, we introduced a collaborative sketch animation system on mobile devices, enabling 2-users to create animation collaboratively in real time. By simple operations, the two users can not only sketch animation collaboratively but also ...

See It is a location-based treasure hunt game designed to promote physical activity amongst players. In the game, players use ambiguous visual clues in the form of images and video clips to find locations containing a hidden container. Players can also ...

Preliminary findings are presented from a qualitative investigation of image making during small group interactions. A discourse-oriented methodology was used to capture and analyze video recordings of conversations involving the creation of drawings. ...

This poster presents newcomer behavior, community behavior and learning in online communities of technical support for Open Source Software.

Distributed collaboration systems use cloud computing services to support synchronous and asynchronous distributed collaboration. We are investigating how the benefits of these remote collaboration technologies can be applied to collocated creative ...

After the Great East Japan Earthquake in Japan 2011, numerous tweets were exchanged on Twitter. Several studies have already pointed out that micro-blogging systems have shown potential advantages in emergency situations, but it remains unclear how ...

3D online virtual worlds are platforms for cooperative applications. They allow users to create customized content. Changes in the system conditions are usually manifested to end users as delays in the shared state. Consistency management and delay ...

This poster describes a conceptual model of a timeline-based mash-up service, which addresses the needs of researchers involved in collaborative scientific writing processes.

In this paper we evaluated an application of creativity techniques with sampling partial data from a large number of idea cards, to reduce operation cost of problem definition or decision-making at critical situation as disasters. In our experiments, we ...

Few studies have shown how older adults cope with communication in an age of social media where many people are in constant contact with one another. To address this, we have studied the current living and communication practices of twelve older adults ...

Our study investigated the use of annotations in an asynchronous crime-solving task. In Study 1, regardless of whether they anticipated a partner, participants had better performance if they annotated more about connections across documents. In Study 2, ...

This study of collaboration among a multidisciplinary team of healthcare workers demonstrates that elements intrinsic to the interaction constitute a delicate ecosystem. As the balance between actors, digital media and paper artefacts fluctuates, so too ...

Though crowdsourcing holds great promise, many struggle with framing tasks and determining which members of the crowd should be recruited to obtain reliable output. In some cases, expert knowledge is desired but, given the time and cost constraints of ...
