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.

Houston professor earns Google Scholar award for quantum computing research

recent recognition

A Rice University quantum computer scientist was one of 78 global professors to be presented with a 2023 Google Scholar award, the university announced this month.

Nai-Hui Chia, an assistant professor of computer science at Rice, was recognized for his research on Hamiltonian simulations, a method for representing the motion of moving particles. Chia aims to understand if quantum computers or machines can simulate a "Hamiltonian matrix" with a shorter evolution time.

"We call this fast-forwarding for a Hamiltonian simulation,” Chia says in a statement.

Chia aims to use the funds from Google to discover Hamiltonians that can be fast-forwarded using parallelism or classical computation, according to Rice. He will present his current work on Hamiltonians and their connection to cryptology in July at the 2023 Computational Complexity Conference in Warwick, UK.

The Google Research Scholar program grants funds of up to $60,000 to support professors' research around the world. This year's cohort works in fields ranging from algorithms and optimization to natural language processing to health research.

Three other Texas researchers were awarded funds in the 2023 cohort.

The University of Texas at Austin's Jon Tamir was awarded for his work in applied sciences. Atlas Wang, also from UT, was awarded in the machine learning and data mining category. Shenglong Xu, from Texas A&M University, joined Chia in the quantum computing category.

Tech behemoth Google has awarded funds to several Houston innovators in recent years.

Last summer the company named AnswerBite, Boxes and Ease to its inaugural cohort of the Google for Startups Latino Founders Fund. Selected companies received an equity-free $100,000 investment, as well as programming and support from Google.

In September 2022, ChurchSpace and Enrichly were named part of the Google for Startups Black Founders Fund. The companies also received $100,000 non-dilutive awards along with mentoring and support.

UH lands $11.8M for first-of-its-kind early language development study

speech funding

Researchers at the University of Houston have secured an $11.8 million grant from the National Institutes of Health to conduct a first-of-its-kind study of early language development.

Led by Elena Grigorenko, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Psychology, and research professor Jack Fletcher, the study will follow 3,600 children aged 18 to 24 months to uncover how language skills develop at this critical stage and why some children experience delays that can influence later growth.

The NIH funding will also support the development of the new national Clinical Research Center on Developmental Language Disorders at UH, which aims to bring experts from psychology, education, health and measurement sciences to study how children learn language.

“This will be the first national study to estimate how common late talking is using a large, representative sample of Houston toddlers,” Grigorenko said in a news release. “By following these children as they grow, we hope to better understand the developmental pathways that can lead to conditions such as developmental language disorder and autism.”

UH’s team will partner with the pediatric clinic network at Texas Children’s Hospital, where children will be screened for early language development, allowing researchers to identify those who show signs of delayed speech. Next, researchers will follow the cohort through early childhood to examine how language abilities evolve and how early delays may lead to later challenges.

The Clinical Research Center on Developmental Language Disorders will be the 14th national research center established at UH, and will include researchers from multiple UH departments, as well as partners at Baylor College of Medicine and the Texas Center for Learning Disorders.

“This level of investment from the National Institutes of Health reflects the significance of this work to address a complex challenge affecting children, families and communities,” Claudia Neuhauser, vice president for research at UH, said in a news release. “By bringing together experts from multiple disciplines and partnering with major health systems across the region, the project reflects our commitment to advancing discoveries that impact our community.”

Rice Alliance names Houston healthtech exec as first head of platform

new hire

The Rice Alliance for Technology and Entrepreneurship has named its first head of platform.

Houston entrepreneur Laura Neder stepped into the newly created role last month, according to an email from Rice Alliance. Neder will focus on building and growing Houston’s Venture Advantage Platform.

The emerging platform, which is being promoted by Rice Alliance and the Ion, aims to connect founders with the "people, capital and expertise they need to scale."

"I’ve spent a lot of time thinking about what it takes to make an innovation ecosystem more navigable, more connected, and more useful for founders," Neder said in a LinkedIn post. "I’m grateful for the opportunity to do that work at Rice Alliance, alongside a team with a long history of supporting entrepreneurship and innovation."

"Houston has the talent, institutions, and industry base to create real advantage for founders," she added. "I’m looking forward to listening, learning, and building stronger pathways across the ecosystem."

Neder most recently served as CEO of Houston-based Careset, where she helped bring the Medicare data startup to commercialization. Prior to that, Neder served as COO of Houston-based telemedicine startup 2nd.MD, which was acquired for $460 million by Accolade in 2021.

"Laura brings a rare combination of founder empathy, operational experience and ecosystem leadership," Rice Alliance shared.

Neder and Rice Alliance also shared that the organization is hiring developers to design the new Venture Advantage Platform. Learn more here.

Elon Musk's SpaceX files initial paperwork to sell shares to the public

Incoming IPO

Elon Musk's space exploration company has filed preliminary paperwork to sell shares to the public, according to two sources familiar with the filing, a blockbuster offering that would likely rank as the biggest ever and could make its founder the world's first trillionaire.

A SpaceX IPO promises to be one of the biggest Wall Street events of the year, with several investment banks lining up to help raise tens of billions to fund Musk's ambitions to set up a base on the moon, put datacenters the size of several football fields in orbit and possibly one day send a man to Mars.

The sources spoke on condition of anonymity because they were not authorized to talk publicly about the confidential registration with the Securities and Exchange Commission.

SpaceX did not respond immediately to a request for comment.

Exactly how much SpaceX plans to raise has not been disclosed but the figure is reportedly as much as $75 billion. At that level, the offering would easily eclipse the $29 billion that Saudi Aramco raised in its IPO in 2019.

The offering, coming possibly in June, could value all the shares of SpaceX at $1.5 trillion, nearly double what the company was valued in December when some minority owners sold their stakes, according to research firm Pitchbook, before an acquisition that increased its size.

Musk owns 42% of the SpaceX now, according to Pitchbook, though that figure will change with the IPO when new owners are issued shares. In any case, he is likely to pierce the trillion dollar mark because he is already close. Forbes magazine estimates Musk's net worth at roughly $823 billion.

In addition to making reusable rockets to hurl astronauts and hardware into orbit, SpaceX owns Starlink, the world’s largest satellite communications company. The company also recently brought under its roof two other Musk businesses, social media platform X, formerly Twitter, and artificial intelligence business, xAI, in a controversial transaction because both the seller and the buyer were controlled by him.

SpaceX has become the biggest commercial launch company in its industry, responsible for sending payloads into orbit for customers across the globe, but has also benefited from big taxpayer spending. That has raised conflicts of interest issues given that Musk was the biggest donor to President Donald Trump's campaign and is still a big backer.

In the past five years, SpaceX won $6 billion in contracts from NASA, the Defense Department and other U.S. government agencies, according to USAspending.gov.

Among current SpaceX owners is Donald Trump Jr, the president's oldest son. He owns a shares through 1789 Capital. That venture capital firm made him a partner shortly after his father won the presidency for a second time and has been buying up federal contractors seeking to win taxpayer money ever since.

The White House and Trump himself have repeatedly denied there are any conflicts of interest between his role as president and his family's businesses.
