We mapped who supports US STEM PhDs. Fed govt by far the main funder, esp in science for critical tech like AI and quantum. Less govt funding -> fewer graduates. Further details: https://t.co/ckzzg4ykm9 Joint with @HansenZhang13, Lee Fleming and @daniel_p_gross

I had the opportunity to speak with Brian Owens at @NatureIndex about why firms invest in scientific research and what drives their decisions to publish their findings. Grateful for the thoughtful reporting: https://t.co/hgUE9LpuYI

Quick update regarding PatentsView metadata: the final datasets, including granted, pre-grant and beta tables, are now available on the I3 BigQuery data repository. Link: https://t.co/9fj5apAcED Join our mailing group:

huge thanks @rogermasclans for leading our first @I3Open Upskilling session! Roger did a 75 minute live demo of big-data wrangling using Google BigQuery and the i3-nber data repository. here's the recording ( https://t.co/tMSIZNpl5R) for anyone interested.

Excited to bring back the Duke Strategy PhD Conference for its second edition! 🎉 A student-run event for PhD candidates in innovation, strategy, and entrepreneurship 📣 Know someone who should apply? Help us spread the word #StrategyTwitter

I'm looking forward to this! We’re hosting lots of innovation data on the @I3Open BigQuery repo. Join us on Feb 21st for our first webinar. Roger Masclans (@rogermasclans) will cover efficient querying, cost optimization, and key use cases. Register here

just a bit more detail on the i3 BigQuery workspace: problems we're trying to solve: ▶️datasets are getting unwieldy. OpenAlex is 400G compressed, takes hours to download / inflate / un-json / assemble. then you merge it... ▶️merging is fraught with identifier mismatches,

Now @DShvadron and @marxmatt are introducing the I3 BigQuery data repository. Look for the project name nber-i3 , and get in touch if you have ideas for adding to and using it. https://t.co/EsRE9kpSsG

@OpenAlex_org We welcome comments, questions, and suggestions. Details and download links are available here:

@OpenAlex_org Making the data available took more time than anticipated. We appreciate your patience and support, and we hope our efforts will greatly benefit the research community.

@OpenAlex_org The dataset, which begins in 1980, now extends through 2021, adding six additional years of data. We have completely rebuilt the matches to patents and publications to ensure continuity and accuracy.

@OpenAlex_org We have significantly enhanced a key feature of DISCERN: its comprehensive coverage of firms' subsidiaries and their ownership changes over time. This improvement is crucial for accurately mapping corporate innovations to the right producers and owners.

DISCERN 2.0 features multiple enhancements. We transition to using open data from the USPTO and @OpenAlex_org. This allows us to openly share with users the complete match between firms and their granted patents, pre-grant patent applications, and scientific publications.

We are pleased to introduce the DISCERN 2.0 dataset, which links patents and scientific publications to U.S. publicly listed firms. Joint work with @SharonBelenzon @ProfAroraAshish @LarisaCioaca and @Lia_Sheer. #econtwitter #StrategyTwitter

Closing out a successful day at the Duke Strategy PhD Conference! A big thank you to all participants. May this be a start of a long-lasting tradition! #StrategyTwitter @DukeFuqua
