The changing landscape of scholarly publishing

August 12, 2021, 12:04PMNuclear NewsJohn Fabian

The academic publishing industry—an industry that was very stable for over a century—is now experiencing a tremendous shift. Attitudes regarding the use, delivery, and costs of publication are at the center of the matter, causing publishers to investigate new publishing models. These changing attitudes require ANS to think differently to improve content offerings while continuing to generate needed revenue. The focus is on two trends: the elimination of author page charges, and the rise of open access publishing. The latter item is a relatively recent phenomenon that has been gaining traction over the past decade, especially in the medical and biology fields, but the former is an issue that has caused friction between authors and publishers for a generation or more.

There is a lot of buzz around advanced reactors, and for good reason, according to Ashley Finan, director of the Department of Energy’s National Reactor Innovation Center (NRIC). In the article 3 Ways to Make Nuclear Power Plants Faster and More Affordable to Build, published earlier this month on the DOE’s website, Finan noted that advanced reactors promise to be cheaper to build and operate, offer enhanced versatility, and can help put the United States on a path to achieving net-zero emissions by 2050.

The key cost driver will be construction and project management, “areas that have plagued the industry for decades,” Finan noted.

“For advanced nuclear energy to realize its potential, we have to make it more affordable and scalable. Only then can it meaningfully contribute to our energy, security, and environmental imperatives,” she added.
