Dr. Mark Palmeri: An honest assessment of openness

This post is part of the Duke Research Data Curation Team’s ‘Researcher Highlight’ series.

In the field of engineering, a key driving motivator is theDr. Mark Palmeri urge to solve problems and provide tools to the community to address those problems. For Dr. Mark Palmeri, Professor in Biomedical Engineering at Duke University, open research practices support the ultimate goals of this work, and helps get the data into the hands of those solving problems: “It’s one thing to get a publication out there and see it get cited. It’s totally another thing to see people you have no direct professional connection to accessing the data and see it impacting something they’re doing…”

Dr. Palmeri’s research focuses on medical ultrasonic imaging, specifically using acoustic radiation force imaging to characterize the stiffness of tissues. His code and data allow other researchers to calibrate and validate processing protocols, and facilitate training of deep learning algorithms. He recently sat down with the Duke Research Data Repository Curation Team to discuss his thoughts on open science and data publishing.

“It’s one thing to get a publication out there and see it get cited. It’s totally another thing to see people you have no direct professional connection to accessing the data and see it impacting something they’re doing…”

With the new NIH data management and sharing policy on the horizon, many researchers are now considering what sharing data looks like for their own work. Palmeri highlighted some common challenges that many researchers will face, such as the inability to share proprietary data when working with industry partners, de-identifying data for public use (and who actually signs off on this process), the growing scope and scale of data in the digital age, and investing the necessary time to prepare data for public consumption. However, two of his biggest challenges relate to the changing pace of technology and the lack of data standards.

ClockWhen publishing a dataset, you necessarily have a static version of the dataset established in space and time via a persistent identifier (i.e., DOI); however, Palmeri’s code and software outputs are constantly evolving as are the underlying computational environments. This mismatch can result in datasets becoming out of sync with the coding tools, thereby affecting future reuse and ultimately keeping things up-to-date takes time and effort. As Palmeri notes, in the fast-paced culture of academia “no one has time to keep old project data up to snuff.”

Likewise, while certain types of data in medical imaging have standardized formats (e.g., DICOM), for the images Palmeri is creating from raw signal data there are no ubiquitous standards. This creates problems for data reuse. Palmeri remarks that “There’s no data model that exists to say what metadata should be provided, in what units, what major fields and subfields, so that becomes a major strain on the ability to meaningfully share the data, because if someone can’t open it up and know how to parse it and unwrap it and categorize it, you’re sharing gigabytes of bits that don’t really help anyone.” Currently, Dr. Palmeri is working with the Quantitative Imaging Biomarkers Alliance and the International Electrotechnical Commision (IEC) TC87 (Ultrasonics) WG9 (Shear Wave Elastography) to create a public standard for this technology for clinical use.

Regardless of these challenges, Palmeri sees many benefits to publicly sharing data including enhancing “our internal rigor even just that little bit more” as well as opening “new doors of opportunity for new research questions…and then the scope and impact of the work can be augmented.” Dr. Palmeri appreciates the infrastructure provided by the Duke University Libraries to host his data in a centralized and distributed network as well as the ability to cite his data via the DOI. As he notes “you don’t want to just put up something on Box as those services can change year to year and don’t provide a really good preserved resource.” Beyond the infrastructure, he appreciates how the curation team provides “an objective third party [to] look at things and evaluate how shareable is this.”

“you don’t want to just put up something on Box as those services can change year to year and don’t provide a really good preserved resource.”

Within the Duke Research Data Repository, we have a mission to help Duke researchers make their data accessible to enable reproducibility and reuse. Working with researchers, like Dr. Palmeri, to realize a future where open research practices lead to a greater impact for researchers and democratizes knowledge is a core driving motivator.

Data Management, repository, research data, version control

Code Repository vs Archival Repository. You need both.

Years ago I heard the following quote attributed to Seamus Ross from 2007:

Digital objects do not, in contrast to many of their analog counterparts, respond well to benign neglect.

Meaning, you cannot simply leave digital files to their bit-rot tendencies while expecting them to be usable in the future.  Digital repositories are part of a solution to this problem.  But to review, there are many types of repositories, both digital and analog:  repositories of bones, insects, plants, books, digital data, etc.  Even among the subset of digital repositories there are many types.  Some digital repositories keep your data safe for posterity and replication.  Some help you manage the distribution of analysis and code.  Knowing about these differences will affect not only the ease of your computational workflow, but also the legacy of your published works.  

Version-control repositories and their hubs

The most widely known social coding hubs include GitHub, Bitbucket and GitLab.  These hubs leverage Git version-control software to track the evolution of project repositories – typically a software or computational analysis project.  Importantly, Git and GitHub are not the same thing but they work well together.

Git repository

Version control works by monitoring any designated folder or project directory, making that directory a local repository or repo.  Among other benefits, using version control enables “time travel.” Interactions with earlier versions of a project are commonplace.  It’s simple to retrieve a deleted paragraph from a report written six months ago.  However there are many advanced features as well. For example, unlike common file-syncing tools, it’s easy to recreate an earlier state of an entire project directory and every file from a particular point in time.  This feature among others makes Git version-control a handy tool in support of many research workflows and the respective outputs:  documents, visualizations, dashboards, slides, analysis, code, software, etc.  

Binary. Michael Coghlan. https://flic.kr/p/aYEytM

Git is one of the most popular, open-source, version-control applications; originally developed in 2005 to facilitate the evolution of the world’s most far reaching and successful open-source coding project.  Linux is a world-wide collaborative project that spans multiple developers, project managers, natural languages, geographies, and time-zones.  While Git can handle large projects, it is extensible and can easily scale up or down to support a wide range of workflows.  Additionally, Git is not just for software and code files.  Essentially any file on a file system can be monitored with Git:   MSWord, PDF files, images, datasets, etc. 

 

There are many ways to share a Git repository and profile your work.  The term push refers to a convenient process of synchronizing a repo up to a remote social coding hub.  Additional features of a hub include issue tracking, collaboration, hosting documentation, and Kanban Method planning.  Conveniently, pushing a repo to GitHub means maintaining a seamless, two-location backup – a push will simultaneously and efficiently synchronize the timeline and file versions. Meanwhile, at a repo editor’s discretion, any collaborator or interested party can be granted access to their GitHub repository.

Many public instances of social-coding hubs operate on a freemium model.  At GitHub most users pay nothing.  It’s also possible to run a local instance of a coding hub.  For example, OIT offers a local instance of GitLab, delivering many of the same features while enabling permissions, authorization, and access Via Duke’s NetID.

While social coding hubs are great tools for distributing files and managing project life-cycles, in and of themselves they do not sufficiently ensure long-term reproducible access to research data.  To do that simply synchronize version-control repositories with archival research data repositories.

Research Data Repositories


Preserving the computational artifacts of formal academic works requires a repository focus that is complementary to version-control repositories and social-coding hubs.  Nonetheless, version control is not a requirement of a data repository where the goal is long-term preservation. Fortunately, many special-purpose data repositories exist.  Discipline-specific research repositories are sometimes associated with academic societies.  There also exist more generalized archival research repositories such as Zenodo.org.  Additionally, many research universities host institutional research data repositories.  Not surprisingly, such a research data repository exists at Duke where the Duke University Libraries promotes and cooperatively shepherds Duke’s Research Data Repository (RDR).

Unlike social coding hubs, data repositories operate under different funding models and are motivated by different horizons.  Coding hubs like GitHub do not promise long-term retention, instead they focus on immediate distribution of version-control repos and offer project management features. Research data repositories take a long view centered closer to the artifacts of formal research and publication.  

By archiving the data milestones of publication, a deposit in the RDR links a formal publication – book edition, chapter, or serial article, etc. – with the data and code (i.e., a compendium) used to produce a single tangible instance of publication.  In turn, the building blocks of computational thinking and research processes are preserved for posterity because the RDR maintains an assurance of long term sustainability.

In the Duke RDR, particular effort is focussed on preserving unique versions of data associated with each formal publication.  In this way, authors can associate a digital object identifier, or DOI, with the precise code and data used to draft an accepted paper or research project.  Once deposited in the RDR, researchers across the globe can look at these archives to verify, to learn, to refute, to cite, or be inspired toward new avenues of investigation.

By preserving workflow artifacts endemic to publication milestones, research data repositories preserve the record of academic progress.  Importantly, the preservation of these digital outcomes or artifacts is strongly encouraged by funding agencies.  Increasingly, these archival access points are a requirement for funding, especially among publicly funded research.  As such, the Duke RDR exists with aims to preserve and make the academic record accessible, and to create a library of reproducible academic research.  

Conclusion

The imperatives for preserving research data are derived from expressly different motives than those driving version-control repositories.  Minimally, version-control repositories do not promise academic posterity.  However, among the drivers of scholarship is the intentional engagement with the preserved academic record.  In reality, while unlikely, your GitHub repository could vanish in the blink of the next Wall Street acquisition. Conversely research data repositories exist with different affordances.  These two types of repositories complement each other.  Once more, they can be synchronized to enable and preserve digital processes that comprise many forms of data-driven research.  Using both types of repositories imply workflows that positively contribute to a scholarly legacy. It is this promise of academic transmission that drives Duke’s RDR, and benefits scholars by enabling access to persistent copies of research.

CDVS Data Workshops: Spring 2022

As we begin the new year, the Center of Data and Visualization Sciences is happy to announce a series of twenty-one data workshops designed to empower you to reach your goals in 2022. With a focus on data management, data visualization, and data science, we hope to provide a diverse set of approaches that can save time, increase the impact of your research, and further your career goals.

While the pandemic has shifted most of our data workshops online, we remain keenly interested in offering workshops that reflect the needs and preferences of the Duke research community. In November, we surveyed our 2021 workshop participants to understand how we can better serve our attendees this spring. We’d like to thank those who participated in our brief email survey and share a few of our observations based on the response that we received.

Workshops Formats

While some of our workshops participants (11%) prefer in-person workshops and others (24%) expressed a preference for hybrid workshops, a little over half of the survey respondents (52%) expressed a preference for live zoom workshops. Our goal for the spring is to continue offering “live” zoom sessions while continuing to explore possibilities for increasing the number of hybrid and in-person options. We hope to reevaluate our workshops communities preferences later this year and will continue to adjust formats as appropriate.

52% of respondents prefer online instruction, while another 24% would like to hybrid options

Participant Expectations

With the rapid shift to online content in the last two years coupled with a growing body of online training materials, we are particularly interested in how our workshop attendees evaluate online courses and their expectations for these courses.  More specifically, we were curious about whether registering for an online session includes more than simply the expectation of attending the online workshop.

While we are delighted to learn that the majority of our respondents (87%) intend to attend the workshop (our turnout rate has traditionally been about 50%), we learned that a growing number of participants had other expectations (note: for this question, participants could choose more than one response). Roughly sixty-seven percent of the sample indicated they expected to have a recording of the session available. While another sixty-six percent indicated that they expected a copy of the workshop materials (slides, data, code) even if they were unable to attend.

As a result of our survey, CDVS will make an increasing amount of our content available online this spring..  In 2021, we launched a new webpage designed to showcase our learning materials. In addition to our online learning site, CDVS maintains a github site (CDVS) as well as site focused on R learning materials (Rfun).

We appreciate your feedback on the data workshops and look forward to working with you in the upcoming year!

Data Management, Open Data

Change is coming – are you open to it?

This blog post is a collaboration between Paolo Mangiafico from ScholarWorks and Sophia Lafferty-Hess from the Center for Data and Visualization Sciences and the Duke Research Data Repository.

Open access journals have been around forOpen sign several decades, and almost all researchers have read them or published in them by now. Perhaps less well known are trends toward more openness in sharing of data, methods, code, and other aspects of research – broadly called open scholarship. There are lots of good reasons to make your research outputs as open as possible, and increasing support at Duke for doing it.

There are many different variants of “open” – including goals of making research accessible to all, making data and methods transparent to increase reproducibility and trust, licensing research to enable broad re-use, and engagement with a variety of stakeholders, among other things. All of these provide benefits to the public and they also provide benefits to Duke researchers. There’s growing evidence that openly available publications and data result in more citations and greater impact (Colavizza 2020), and showing one’s work and making it available for replication helps build greater trust. There’s greater potential economic impact when others can build on research more quickly, and more avenues for collaboration and interdisciplinary engagement.

Recognizing the importance of making research outputs quickly and openly available to other researchers and the public, and supporting greater transparency in research, many funding agencies are now encouraging or requiring it. NIH has had a public access policy for over a decade, and NSF and other agencies have followed with similar policies. NIH has also released a new Data Management and Sharing policy that goes into effect in 2023 with more robust and clearer expectations for how to effectively share data. In Europe, government research funders back a program called Plan S, and in the United States, the recently passed U.S. Innovation and Competition Act (S. 1260) includes provisions that instruct federal agencies to provide free online public access to federally-funded research “not later than 12 months after publication in peer-reviewed journals, preferably sooner.”

The USICA bill aims to maximize the impact of federally-funded research by ensuring that final author manuscripts reporting on taxpayer-funded research are:

  • Deposited into federally designated or maintained repositories;
  • Made available in open and machine-readable formats; 
  • Made available under licenses that enable productive reuse and computational analysis; and
  • Housed in repositories that ensure interoperability and long-term preservation.

Duke got a head start on supporting researchers in making their publications open access in 2010, when Academic Council adopted an open access policy, which since then has been part of the Faculty Handbook (Appendix P). The policy provides the legal basis for Duke faculty to make their own research articles openly available on a personal or institutional website via a non-exclusive license, while also making it possible to comply with any requirements imposed by their journal or funder. Shortly after the policy was adopted, Duke Libraries worked with the Provost’s office to implement a service making open access easy for Duke researchers. DukeSpace, a repository integrated with the Scholars@Duke profile system, allows you to add a publication to your profile and deposit it to Duke’s open access archive in a single step, and have the open access link included in your citations alongside the link to the published version.

Duke Libraries also support a research data repository and services to help the Duke community organize, describe, and archive their research data for open access. This service, with support from the Provost’s office, provides both the infrastructure and curation staff to help Duke researchers make their data FAIR (Findable, Accessible, Interoperable, and Reusable). By publishing datasets with digital object identifiers (DOIs) and data citations, we create a value chain where making data available increases their impact and positions them as standalone research objects. The importance of data sharing specifically is also being formalized at Duke through the current Research Data Policy Initiative, which has a stated mission to “facilitate efficient and quality research, ensure data quality, and foster a culture of data sharing.” Together the Duke community is working to develop services, processes, procedures, and policies that broaden our contributions to society through public access to the outputs of our research.

Are you ready to make your work open? You can find more information about how to deposit your publications and data for open access at Duke on the ScholarWorks website, and consultants from Duke Libraries’ ScholarWorks Center for Scholarly Publishing and Center for Data and Visualization Sciences are available to help you find the best place to make your work open access, choose an appropriate license, and track how it’s being used.

Share More Data in the Duke Research Data Repository!

We are happy to announce expanded features for the public sharing of large scale data in the Duke Research Data Repository! The importance of open science for the public good is more relevant than ever and scientific research is increasingly happening at scale. Relatedly, journals and funding agencies are requiring researchers to share the data produced during the course of their research (for instance see the newly released NIH Data Management and Sharing Policy). In response to this growing and evolving data sharing landscape, the Duke Research Data Repository team has partnered with Research Computing and OIT to integrate the Globus file transfer system to streamline the public sharing of large scale data generated at Duke. The new RDR features include:

  • A streamlined workflow for depositing large scale data to the repository
  • An integrated process for downloading large scale data (datasets over 2GB) from the repository
  • New options for exporting smaller datasets directly through your browser
  • New support for describing and using collections to highlight groups of datasets generated by a project or group (see this example)
  • Additional free storage (up to 100 GB per deposit) to the Duke community during 2021!

While using Globus for both upload and download requires a few configuration steps by end users, we have strived to simplify this process with new user documentation and video walk-throughs. This is the perfect time to share those large(r) datasets (although smaller datasets are also welcome!).

Got Data? Data Publishing Services at Duke Continue During COVID-19

1 Comment

While the library may be physically closed, the Duke Research Data Repository (RDR) is open and accepting data deposits. If you have a data sharing requirement you need to meet for a journal publisher or funding agency we’ve got you covered. If you have COVID-19 data that can be openly shared, we can help make these vital research materials available to the public and the research community today. Or if you have data that needs to be under access restrictions, we can connect you to partner disciplinary repositories that support clinical trials data, social science data, or qualitative data.

Speaking of the RDR, we just completed a refresh on the platform and added several features!

In-line with data sharing standards, we also assign a digital object identifier (DOI) to all datasets, provide structured metadata for discovery, curate data to further enhance datasets for reuse and reproducibility, provide safe archival storage, and a standardized citation for proper acknowledgement.

Openness supports the acceleration of science and the generation of knowledge. Within the libraries we look forward to partnering with Duke researchers to disseminate their research data!

Duke University Libraries Partners with the Qualitative Data Repository

Duke University Libraries has partnered with the Qualitative Data Repository (QDR) as an institutional member to provide qualitative data sharing, curation, and preservation services to the Duke community. QDR is located at Syracuse University and has staff and infrastructure in place to specifically address some of the unique needs of qualitative data including curating data for future reuse, providing mediated access, and assisting with Data Use Agreements.

Duke University Libraries has long been committed to helping our scholars make their research openly accessible and stewarding these materials for the future. Over the past few years, this has included launching a new data repository and curation program, which accepts data from any discipline as well as joining the Data Curation Network. Now through our partnership with QDR we can further enhance our support for sharing and archiving qualitative data.

Qualitative data come in a variety of forms including interviews, focus groups, archival materials, textual documents, observational data, and some surveys. QDR can help Duke researchers have a broader impact through making these unique data more widely accessible.

“Founded and directed by qualitative researchers, QDR is dedicated to helping researchers share their qualitative data,” says Sebastian Karcher, QDR’s associate director. “Informed by our deep understanding of qualitative research, we help researchers share their data in ways that reflect both their ethical commitments and do justice to the richness and diversity of qualitative research. We couldn’t be more excited to continue our already fruitful partnership with Duke University Libraries”

Through this partnership, Duke University Libraries will have representation on the governance board of QDR and be involved in the latest developments in managing and sharing qualitative data. The libraries will also be partnering with QDR to provide virtual workshops in the spring semester at Duke to enhance understanding around the sharing and management of qualitative research data.

OSF@Duke: By the Numbers and Beyond

The Open Science Framework (OSF) is a data and project management platform developed by the Center for Open Science that is designed to support the entire research lifecycle. OSF has a variety of features including file management and versioning, integration with third-party tools, granular permissions and sharing capabilities, and communication functionalities. It also supports growing scholarly communication formats including preprints and preregistrations, which enable more open and reproducible research practices.

In early 2017, Duke University became a partner institution with the OSF. As a partner institution, Duke researchers can sign into the OSF using their NetID and affiliate a project with Duke, which allows it to be displayed on the Duke OSF page. After 2 years of supporting OSF for Institutions here at Duke, the Research Data Management (RDM) team wanted to gain a better perspective surrounding how our community was using the tool and their perceptions. 

As of March 10, 2019, Duke has 202 users that have signed into the system using their Duke credentials (and there are possibly more users that are authenticating using personal email accounts). Of these users, 177 total projects have been created and affiliated with Duke. Forty-six of these projects are public and 132 remain private. Duke users have also registered 80 Duke affiliated projects, 62 of which are public and 18 are embargoed. A registration is a time-stamped read-only copy of an OSF project that can be used to preregister a research design, to create registered reports for journals, or at the conclusion of a project to formally record the authoritative copy of materials.

But what do OSF users think of the tool and how are they using it within their workflows? A few power users shared their thoughts:

Optimizing research workflows: A number of researchers noted how the OSF has helped streamline their workflows through creating a “central place that everyone has access to.” OSF has helped “keeping track of the ‘right’ version of things” and “bypassing the situation of having different versioned documents in different places.” Additionally, the OSF has supported “documenting workflow pipelines.”

Facilitating collaboration: One of the key features of the OSF is that researchers, regardless of institutional affiliation, can contribute to a project and integrate the tools they already use. Matt Makel, Director of Research at TIP, explains how OSF supports his research – “I collaborate with many colleagues at other institutions. OSF solves the problem of negotiating which tools to use to share documents. Rather than switching platforms across (or worse, within) projects, OSF is a great hub for our productivity.”

Offering an end-to-end data management solution: Some research groups are also using OSF in multiple stages of their projects and for multiple purposes. As one researcher expressed – “My research group uses OSF for every project. That includes preregistration and archiving research materials, data, data management and analysis syntax, and supplemental materials associated with publications. We also use it to post preprints to PsyArXiv.”

It also surfaced that OSF supported an ideological perception regarding a shift in the norms of scholarly communication. As Elika Bergelson, Crandall Family Assistant Professor in Psychology and Neuroscience, aptly put it “Open science is the way of the future.” Here within Duke University Libraries, we aim to continue to support these shifting norms and the growing benefits of openness through services, platforms, and training.

To learn more about how the OSF might support your research, join us on April 3 from 10-11 am for hands-on OSF workshop. Register here: https://duke.libcal.com/event/4803444

If you have other questions about using the OSF in a project, the RDM team is available for consultations or targeted demonstrations or trainings for research teams. We also have an OSF project that can help you understand the basic features of the tool.

Computational Reproducibility Pilot – Code Ocean Trial

A goal of Duke University Libraries (DUL) Code Ocean Logois to support the  growing and changing needs of the Duke research community. This can take many forms. Within Data and Visualization Services, we provide learning opportunities, consulting services, and computational resources to help Duke researchers implement their data-driven research projects. Monitoring and assessing new tools and platforms also helps DUL stay in tune with changing research norms and practices. Today the increasing focus on the importance of transparency and reproducibility has resulted in the development of new tools  and resources to help researchers produce and share more reproducible results. One such tool is Code Ocean.

Code Ocean is a computational reproducibility platform that employs Docker technology to execute code in the cloud. The platform does two key things—it integrates the metadata, code, data and dependencies into a single ‘compute capsule’, ensuring that the code will run—and it does this in a single web interface that displays all inputs and results. Within the platform, it is possible to develop, edit or download the code, run routines, and visualize, save or download output, all from a personal computer. Users or reviewers can upload their own data and test the effects of changing parameters or modification of the code. Users can also share their data and code through the platform. Code Ocean provides a DOI for all capsules facilitating attribution and a permanent connection to any published work.

In order to help us understand and evaluate the usefulness of the Code Ocean platform to the Duke research community, DUL will be offering trial access to the Code Ocean cloud-based computational reproducibility platform starting on October 1, 2018. To learn more about what is included in the trial access and to sign up to participate, visit the Code Ocean pilot portal page.

If you have any questions, contact askdata@duke.edu.
