Chao, Tiffany C. (2012): Exploring the rhythms of scientific data use. In: Proceedings of the 2012 iConference 2012. pp. 129-135. http://dx.doi.org/10.1145/2132176.2132193

A better understanding of scientific data practices is needed to inform the continued development of infrastructures to support long-term use of research data. In this paper, the conceptual framework of 'rhythms' is employed in a qualitative analysis of data practices in the domain of earth science to explain the use of data types over time, from a biographical, organizational, phenomenal, and infrastructural perspective. By tracing the rhythms associated with two specific data types -- physical field samples and computational model output -- patterns of short-term and long-term use within subdisciplines and their relationships to scientists' perceptions and behaviors connected with the scholarly value of these data types begin to emerge. Preliminary results suggest that data rhythms should be understood as part of the service context for the curation and long-term maintenance of research data.

Cragin, Melissa H., Chao, Tiffany C. and Palmer, Carole L. (2011): Units of evidence for analyzing subdisciplinary difference in data practice studies. In: JCDL11 Proceedings of the 2010 Joint International Conference on Digital Libraries 2011. pp. 441-442. http://dx.doi.org/10.1145/1998076.1998175

Digital libraries (DLs) are adapting to accommodate research data and related services. The complexities of this new content spans the elements of DL development, and there are questions concerning data selection, service development, and how best to align these with local, institutional initiatives for cyberinfrastructure, data-intensive research, and data stewardship. Small science disciplines are of particular relevance due to the prevalence of this mode of research in the academy, and the anticipated magnitude of data production. To support data acquisition into DLs -- and subsequent data reuse -- there is a need for new knowledge on the range and complexities inherent in practice-data-curation arrangements for small science research. We present a flexible methodological approach crafted to generate data units to analyze these relationships and facilitate cross-disciplinary comparisons.

Chao, Tiffany C. (2011): Data repositories: a home for microblog archives?. In: Proceedings of the 2011 iConference 2011. pp. 655-656. http://dx.doi.org/10.1145/1940761.1940857

In April 2010, the popular microblogging service, Twitter, announced the donation of their archives to the Library of Congress. This event served to validate the value of microblogs as a source for scholarly research, yet access to the Twitter archives by the public continues to remain restricted. This study seeks to understand how the data repository community can be leveraged to support and maintain access to microblog data for long-term use. Through the examination of a sample Twitter aggregation, significant properties for preservation will be identified and applied to current standards and criteria set by data repositories for deposit. The analysis of data repository functions and the properties of the microblog aggregation provides further awareness into the preservation practices and policies of these social memory institutions while also illuminating recommendations for advancing these retention strategies and approaches.
