Model of Coordinated Action (MoCA)

The Model of Coordinated Action (MoCA) represents a bold initiative to leverage ethnographic or qualitative research in the field of Computer Supported Cooperative Work (CSCW) in an unprecedented manner. By finding a way to compare studies of practice, we aim to contribute to the generalizability of previously generalizable findings and also to the production of data-driven design guidance that is tailored for different kinds of collaborative settings and organizations.

MoCA is a conceptual framework for describing complex collaborative situations and environments including, but not limited to, collaborations that have diverse, high-turnover memberships or emerging practices. MoCA consists of seven dimensions of coordinated action. Each of these “dimensions” fall on a continuum. This new conceptual mapping of types of collaborative work enables a fuller representation of the design space for collaborative systems. By focusing this model on collaboration per se, we open up more room to investigate how multiple technologies can be mapped to a single coordinated action—a sociotechnical aggregation of actors and technologies.

Interacting with Cyberinfrastructure in the Face of Changing Science

Information for Study Participants & Researchers
NSF Award IIS-0954088*

This research will develop a framework to understand the set of sociotechnical relationships that comprise cyberinfrastructure (CI). The technical challenges of cyberinfrastructure are already so demanding that projects often have little time to engage reflexively on how cyberinfrastructures are used and created in the current state of rapid scientific change in which the necessity of data sharing and multidisciplinary approaches is putting pressure on disciplinary boundaries. This project will investigate: How scientists and engineers decide which cyberinfrastructure resources (e.g. databases and tools) to use and under what circumstances; Under what circumstances do scientists and engineers decide to create their own resources; How are scientists and engineers mixing disciplinary practices within their own laboratories; When do scientists and engineers adopt hybrid identities (e.g. computational biologists and bioinformaticists).

Currently in its third year the Interacting with Cyberinfrastructure in the Face of Changing Science study has enrolled six different research groups as study sites. The disciplines of these six groups range from biological sciences to astronomy and seismology. Examining the work of the six groups, this research is currently examining how data and software artifacts support the collaborative work of these scientists. Specifically the research team is probing how different sources of data may help to structure collaborative work by using the concept of coordinative artifacts from the field of CSCW.

Scientists and their Software: A Sociotechnical Investigation of Scientific Software Development and Sharing

NSF Award ACI-1302272
PI: Charlotte P. Lee
Graduate student Drew Paine helped co-author this proposal.

This research project will examine how scientists develop Scientific Cyberinfrastructure Software (SCIS) as part of their day-to-day research practice through a qualitative, ethnographic study of 6 research groups using observations, semi-structured interviews, and document analysis. Despite the importance of SCIS for data-intensive research, too little is known about how scientists use, adopt, and develop scientific software. More research is needed to explore how software, software development, and software sharing practices are, and can be, community products, resources, or practices. Understanding SCIS development and sharing is necessary to ensure continued integrity of datasets shared within and among communities, facilitate the sharing of the tools and practices that are developed using national research funds, and most importantly continue to support a fundamental tenet of scientific research: the open communication of the processes and practices behind published research findings.

The aims of this study are: (1) Investigating how decisions are made and document, classify, and analyze actual practices for using, adopting, developing, or sharing software; (2) Identify scientists’ incentives and disincentives to share software at the local, organizational, and community levels; and (3) Discern the impacts, intentional and unintentional, that scientific cyberinfrastructure software systems have on scientific data and the scientific research process.

Stakeholder Participation and the Emergence of Dominant Design in Cyberinfrastructure Systems

Charlotte P. Lee (PI), E. Ilana Diamant (Post-Doc)
NSF Award OCI-1220269

This project examines the social processes in the design of cyberinfrastructures, focusing on the role that different stakeholders play in design and development, the ways in which their interests and priorities can be aligned, and the social organization of the development effort.

More specifically, this project examines the development and evolution of the GENI.net cyberinfrastructures (PlanetLab, ProtoGeni, ORBIT, ORCA). The goal of this research is to develop a framework for understanding how cyberinfrastructure designs emerge and evolve over time (to that end, we are looking into various theoretical approaches beyond the “dominant design” approach that we originally proposed). We are conducting a qualitative study of the interactions between developers, experimenters and other GENI stakeholders, and of their involvement in the design and development processes across its four cyberinfrastructures.
The long-term goal of our research is to contribute research and practical knowledge to the area of cyberinfrastructure design and large-scale IT development.

Identifying the Information Needs of Low-income Parents Who Shop at Farmers Markets

Food systems include a wide variety of things from seeds and soil, to tractors, to farmers and their communities, to consumers and their communities, to people, businesses and factories that grow, package, process, distribute, or consume food. Understanding food system infrastructure is important for ensuring equal access to healthy, safe food. More abstract things like culture and policies can also be part of a food system. Farmers markets are a small part of a larger food system, but as a point of confluence for many food system stakeholders, they are a promising place to start working towards sustainable and healthy food practices.

Using ethnographic methods and a grounded theory approach, we interviewed and observed low-income parents who were eligible for government food subsidies while they shopped at farmers markets. The findings presented here illustrate the information needs of a low-income people that shop at a farmers market and explore the implications for technologies that may better support the practices of low-income parents looking for affordable, fresh food and vegetables and that help sustain farmers markets.

The Role of Coordinating Centers in Collaborative Cancer-Epidemiology Studies

NIH R03CA150036
PI: Betsy Rolland, Charlotte P. Lee

Although it is tacitly recognized that a good Coordinating Center (CC) is essential to the success of any multi-site collaborative project, little study has been done on what makes a good CC successful, why some CCs fail, or how to build a CC that meets the needs of a given project. Collectively, there is a great amount of knowledge on CCs in the scientific community, yet that knowledge is not being recorded and shared in a systematic, scientific way. The long-term goal of our research is to make collaborative biomedical research, especially cancer-epidemiology research, more efficient and effective through greater understanding of how the research is done and how it can be better supported. We want to find ways to minimize the administrative burden of collaborative research and leave investigators more time to focus on their science.

The four aims of this study are (1) Identify and describe models of CCs and corresponding models of collaborative cancer-epidemiology research projects; (2) Develop metrics that CCs can use to predict and evaluate their performance; (3) Build a downloadable toolkit to help CCs ramp up their operations efficiently and effectively; and (4) Produce a modular course to develop and train CC staff.

In addition to the aims mentioned above, Betsy Rolland (HCDE PhD student) will also be seeking to answer the question of how coordinating centers facilitate collaboration among diverse sites around data harmonization and biospecimen sample sharing. This will serve as her dissertation research.

Collaboration in the Development of Cyberinfrastructure

NSF Award IIS-0712994
Cyberinfrastructures are large-scale distributed scientific enterprises supported primarily through advanced technological infrastructures such as supercomputers and high speed networks. This project systematically studied the actual practices of cyberinfrastructure development and use and is also examining the transformations that it is created to engender. Ethnographic methods were used including participant-observation and semi-structured interviews. A nascent metagenomic cyberinfrastructure project served as the field site.

Leveraging Development Expertise Across Cyberinfrastructures

NSF Award OCI-0838601
This project is undertook an unprecedented 18-month comparative ethnographic study of two large cyberinfrastructure building and research organizations: the National Center for Supercomputing Applications and the San Diego Supercomputer Center. Each of these organizations hosts and participates in multiple cyberinfrastructure projects of varying size and complexity. Qualitative research methods included participant-observation and semi-structured interviews to understand how work practices change and develop over time.

Kindle DX Pilot

kindle2
In Fall 2009, each incoming University of Washington Computer Science & Engineering graduate student received a Kindle DX, Amazon’s latest wireless reading device, to use in place of traditional printed textbooks and research papers in their first-year graduate courses. The students also received textbooks and other required reading materials free of charge for the Kindle DX. The results of our study were written up in a paper that received a Best Paper Nomination at CHI 2011. [more information]

Investigating Online Calendar Sharing Practices

Google Research Award

Calendar sharing is complex because it involves sharing among people who have very different types of relationships and who engage in very different types of activities. We know that people use online calendaring systems for many reasons other than scheduling meetings or activities, but little is known about these other behaviors. We used Google Calendar (GCal) as a technically constrained field of activity that has social implications for the people who use such calendaring systems. This study investigated how people negotiate their activities and relationships through calendar sharing. The results of this study were written up in two papers presented at CSCW 2012 and 2013.

Understanding University Students’ Facilitation of Articulation Work on Collaborative Engineering and Design Projects

Alexander Thayer, HCDE PhD Candidate, conducted dissertation research into the decisions that engineering and design students make to use specific information sources, technologies, and artifacts to externalize the thinking around how to approach a collaborative project. The goals of the project were as follows:

  • Examine engineering and design students’ collaborative information practices and artifact production processes while engaged in group work creating design products
  • Understand how engineering and design students rely on the knowledge work artifacts they produce while working together to inform their choices about the final design products they submit as the result of their collaborative activity
  • Understand engineering and design students’ reasons for using different information technologies (e.g., e-readers, tablet computers, printed texts) for different purposes and at different times in the context of their group work activities
  • Suggest a set of design implications for information technologies that are grounded in how engineering and design students collaborate on large group projects
