Every researcher needs a Digital Persistent Identifier.

As a researcher, what is more important to you than a record of your research and scholarship? A Digital Persistent Identifier, or DPI, distinguishes you and your work from that of your peers – and having one will be mandated for those receiving federal funding. Let’s take a deeper look at why this number is so important. We’ll also compare the different platforms— ORCID, Web of Science, Scopus and Google Scholar — so that you can be sure your publications, presentations, peer reviews and even information about who is citing you are being properly stored and accessed.

ORCID

There are many types of profiles and DPIs that can meet your needs, but there’s no silver bullet. Placing your work onto multiple platforms is necessary according to Andrea Malone, Research Visibility and Impact Coordinator at UH Libraries. She cautions researchers to “be realistic about how many identifiers you can maintain.”

The most popular is ORCID, which stands for Open Researcher and Contributor ID. It’s free to set up, and there is no chance of accidentally or on-purpose having multiple ORCID accounts – it’s assigned to you like a social security number and follows you, the researcher. This comes in particularly especially handy for researchers with common names.

An identifier is federally mandated for those receiving governmental funds. It is not specified that ORCID must be that identifier. For example, according to Malone: “a Web of Science profile also assigns an identifier, which would also satisfy the mandate.” But most researchers choose ORCID because it’s publicly available with no access restrictions.

While an ORCID number is free for researchers, there is a subscription fee for an institution to be associated with ORCID. Information will not pre-populate in an ORCID profile and it doesn’t track citation counts – it only shows what you put in. There are, however, linking wizards that allow you to link from Web of Science and Scopus to your ORCID account. If you choose this option, citations will automatically populate in your ORCID profile. It’s up to the researcher to doublecheck to be sure the information has automated, however.

Google Scholar

Google Scholar is a profile, not an identifier, so it does not comply with federal funding requirements. It is free, however, and it pulls from the open web. You can choose to have your list of articles updated automatically, review the updates yourself or manually update your articles at any time. Google Scholar also specifies which articles are open access. A PDF or HTML icon will appear on the righthand side of each citation for one to download articles.

Web of Science Vs. Scopus

Scopus is known for covering more journals and a wider range of metrics to evaluate research impact than Web of Science. Different platforms are a go-to for certain disciplines – for example, Web of Science is usually associated with hard sciences, although investigators in the social sciences and humanities also place their work on this platform from time to time. It’s a good idea to check out which platforms others in your discipline are using for their profiles.

Staying up-to-date

Of course, DPIs don’t work as intended unless researchers keep their profiles current. That means you need to check your profile after every publication and every time you switch to a new institution. Just as you would update your CV, you must update your ORCID or other DPI profile.

One tactic Malone suggests is setting a schedule either biweekly or monthly to check all your profiles. “One thing that’s helpful is that with all of them, you can set up alerts and create an alert as often as you want,” Malone goes on. “At that time, the program will scrawl the content within the source and alert you to anytime any of your publications appear in their database.”

The Big Idea

No one tool can paint a complete picture of all your scholarship. Be strategic and intentional about which platforms you use. Consider your audience, the platforms others in your discipline use and make sure you have an ORCID profile to comply with the federal mandate. But be careful not to sign up for more than you can feasibly maintain and keep current.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.
