Advancing Data Curation and Archiving: an Application of Coding to Lab Management in the Geosciences

<p>Increases in technology have rapidly advanced the capabilities and ubiquity of scientific instrumentation. Coupled with the demand for increased transparency and reproducibility in science, these advances have necessitated new systems of data management and archival practices. Laboratories are working to update their methods of data curation in line with these evolving best-practices, moving data from often disorderly private domains to publicly available, collaborative platforms. At the Hamilton Isotope Laboratory (HIL) of Hamilton College, the isotope ratio mass spectrometer (IRMS) is utilized across STEM disciplines for a combination of student, faculty, and course-related research, including both internal and external users. With over 200 sets of analytical runs processed in the past five years, documenting instrument usage and archiving the data produced is crucial to maintaining a state-of-the-art facility. However, previous to this project, the HIL faced significant barriers to proper data curation, storage, and accessibility including: a) data files were produced with variable format and nomenclature; b) data files were difficult to interpret without explanation from the lab technician; c) key metadata tying results to respective researchers and projects were missing; d) accessibility to data was limited due to storage on an individual computer; and e) data curation was an intellectual responsibility and burden for the lab technician. Additionally, as the HIL is housed within an undergraduate institution, the high rate of turnover for lab groups created additional barriers to the preservation of long-term, institutional knowledge, as students worked with the HIL for a year or less. These factors necessitate the establishment of new data management practices to ensure accessibility and longevity of scientific data and metadata. In this project, 283 Excel files of previously recorded data generated by the HIL IRMS were modified and cleaned to prepare data for submission to EarthChem, a public repository for geochemical data. Existing Excel files were manually manipulated, several original R code scripts were generated and employed, and procedures were established to backtrace projects and collect key metadata. Most critically, a new internal system of data collection was established with standardized nomenclature and framework. For future usage of the IRMS, data will be exported directly into a template compatible with EarthChem, thereby removing barriers for principal investigators (PIs) and research groups to archive their data in the public domain upon completion of their projects and publications.</p>

Book Reviews

Christophre Georges of the Department of Economics, Hamilton College reviews “Handbook of Computational Economics. Volume 4. Heterogeneous Agent Modeling,” edited by Cars Hommes and Blake LeBaron. The Econlit abstract of this book begins: “Fourteen papers, comprising a handbook for professional researchers and advanced graduate students, survey behavioral heterogeneity as a critical part of the modeling framework and empirical work.”

Book Reviews

Christophre Georges of the Department of Economics, Hamilton College reviews “Economics with Heterogeneous Interacting Agents: A Practical Guide to Agent-Based Modeling,” edited by Alessandro Caiani, Alberto Russo, Antonio Palestrini, and Mauro Gallegati. The Econlit abstract for this book begins: “Text for graduate and PhD students, as well as undergraduates with some knowledge of computers and economics comprises four papers emerging from a workshop on agent-based modeling held by the Dipartimento di Scienze Economiche e Sociali at the Università Politecnica delle Marche. Presents a guide to agent-based models (ABM) and the technicalities that need to be solved in order to evaluate the effect of different rules and their switching.”

Collaborations in Liberal Arts Colleges in Support of Digital Humanities

The field of digital humanities has been rapidly expanding over the course of the last decade. As such, academic institutions have been working to identify ways of supporting these new endeavors in a time of economic struggles. The Digital Humanities Initiative (DHi) at Hamilton College was conceived as one possible model of supporting digital humanities scholarship at a liberal arts institution. The DHi model relies heavily on collaboration among different teams in the Library and Information Technology Services across campus, and with institutions across the United States. DHi also has international partnerships that promote its goals in research, learning, and public humanities. This chapter will describe the various collaborations of DHi and offer suggestions for how others can implement similar support models at their institutions.

Beyond the Back Room

Many professors and students are surprised to learn about the variety of skills metadata and catalog librarians possess that can benefit their digital humanities projects. Metadata and catalog librarians already have experience in areas such as developing project metadata schemas and controlled vocabularies, as well as providing suggestions for project organization, and have the basic abilities needed to support learning new skills such as XML and TEI. This chapter will offer perspectives on how a metadata and catalog librarian can contribute to digital humanities projects. A case study focusing on the involvement of the Metadata and Catalog Librarian with the Digital Humanities Initiative (DHi) at Hamilton College will be used to illustrate one example of how to become successfully involved in digital humanities research on campus.
