Crowded Out: The Competitive Landscape of Contemporary International NGOs
(Cambridge University Press, 2025) Bush, Sarah Sunn; Hadden, Jennifer
Crowded Out delves into the complex landscape of international non-governmental organizations (INGOs). Bush and Hadden trace INGOs' rise to prominence at the end of the twentieth century and three significant but overlooked recent trends: a decrease in new INGO foundings, despite persistent global need; a shift toward specialization, despite the complexity of global problems; and a dispersal of INGO activities globally, despite potential gains from concentrating on areas of acute need. Assembling a wealth of new data on INGO foundings, missions, and locations, Bush and Hadden show how INGOs are being crowded out of dense organizational environments. They conduct case studies of INGOs across issue areas, relying on dozens of interviews and a large-scale survey to bring practitioners' voices to the study of INGOs. To effectively address today's global challenges, organizations must innovate in a crowded world.

Cataloging computer-generated resources: past, present, and possible future
(Taylor & Francis, 2025-06-21) Hovde, Sarah
The article discusses how catalogers describe resources generated by artificial intelligence and how these resources could be represented in bibliographic records. It briefly reviews the history and current state of computer-generated resources, as well as the concept of authorship in cataloging standards. It then provides an overview of the history of cataloging approaches to non-human authors, including the PCC's recent FAQ on "Cataloging of Resources Generated Using Artificial Intelligence (AI) Software." The article finishes by evaluating the PCC guidance and suggesting a range of alternative and/or additional practices that catalogers could adopt.

Molecular Layer Deposition of a Polymeric Crown Ether
(2025-07-10) Laiu, Darrin; Wang, Haotian; Kozen, Alexander C.; Lee, Sang Bok; Rubloff, Gary; Gregorczyk, Keith E.; Rubloff, Gary; Gregorczyk, Keith
Crown ethers (CEs) are macrocyclic molecules known for their ion-selective complexation and have been widely used in solution-phase systems for sensing, separation, and ion transport. Despite their well-characterized coordination chemistry and thermal stability, their integration into vapor-phase thin film fabrication has not been previously demonstrated. In this work, we report the first molecular layer deposition of a crown ether–containing polymer using 4,10-diaza-15-crown-5 (15AC5) and malonyl chloride (MC) as precursors. In-situ spectroscopic ellipsometry confirms layer-by-layer growth behavior, while X-ray photoelectron spectroscopy (XPS) offers strong evidence that the crown ether ring is preserved due to the presence of both C-O-C oxygen in the 15AC5 ring and C=O oxygen in the MC. Comparison between measurement and Ab initio simulations of the valence band spectra support the observed bonding structure and further validate the retention of molecular integrity during deposition. These findings establish a new route for incorporating functional macrocycles into conformal, nanoscale coatings.

An Exploratory Analysis of Campus Engagement with Library GIS and Data Services
(2025) Anza Garcia, Jose Francisco; Harmon, Anna; Shanker, Stella; Jin, Shujian; Budhathoki, Milan
McKeldin Library's GIS and Data Services team provides a variety of geospatial- and data science-related services to the UMD community, including one-on-one consultations, technical support, and educational workshops. To better understand the team's patron base and the potential impact of location on the reach of our services, we conducted an exploratory analysis on our transaction intake data, combining spatial and non-spatial methods to generate insights. We discovered that most of our patrons' departments were reachable within a 5-min walking distance, with dramatic drop-offs occurring at 10- and 15-min thresholds. In addition, two important "hotspots" of activity were identified: the Architecture building and the Hornbake/Plant Sciences complex.
