Northwestern presents at 2019 AAAS conference

Three Northwestern University researchers will present at the 2019 American Association for the Advancement of Science (AAAS) Annual Meeting in Washington, D.C.  The conference runs Feb. 14-17 at the Washington Marriott Wardman Park.

Events featuring Northwestern researchers are summarized below. All event times are listed in Eastern Time.

Diagnosing a Paint Disease with Computer Science: The Case of Georgia O'Keeffe

Scientific session:
Sunday, Feb. 17, 9-9:30a.m. ET
Washington 1, Marriott Wardman Park

Associated press briefing: "Art Conservation Leverages Advanced Scientific Knowhow"
Saturday, Feb. 16, 9 a.m. ET
Balcony A, Marriott Wardman Park


Multimedia materials and news release available

Georgia O’Keeffe (1887-1986) was an American artist whose paintings are now considered essential pieces of visual culture in the early 20th century. Her paintings produced after 1920 often have damaging metal soap aggregates protruding from their surfaces. The complex histories of these works, or “patient histories”, together with molecular characterization and imaging, are computationally correlated to the occurrence of these aggregates with an aim to slow the deterioration of these artworks.

Collective Intelligence in Space Crews

Scientific session:
Sunday, Feb. 17, 1:30-2 p.m. ET
Maryland Suite, Marriott Wardman Park

Associated press briefing: "Missions to Mars: Understanding and Preparing Teams for the Future"
Sunday, Feb. 17, 10 a.m. ET 
Balcony A, Marriott Wardman Park, with questions to follow in the Buchanan Room


Multimedia materials and news release available

Crews venturing into deep space will experience unprecedented autonomy and unpredictable challenges. Effective team performance on a variety of tasks, aka collective intelligence, is critical to mission success. Tracing the collective intelligence of four analog space crews shows that while they generally improved on psychomotor performance, they all declined on key aspects of collective intelligence, creative thinking and problem solving, as their time in isolation and confinement increased.

Development of a Transdisciplinary Scale to Measure Household Water Insecurity

Flash talk: Friday, Feb. 15, 10:10-10:20 a.m. ET


Water insecurity, the inability to access affordable, adequate, reliable, and safe water for a healthy life, is a pressing global problem. Although the need for water is universal, the study of water security has been bounded by disciplinary, sectoral, and geographic silos, such that there has been no standard metric for assessing household water insecurity. It is difficult, but enormously important, to have data on household-level water insecurity that are comparable across settings in order to test the many plausible social, political, health, and economic consequences of water insecurity. As such, the speaker will describe the development and implications of the first scale to measure household water insecurity in a cross-culturally equivalent way. She will describe the development of a consortium of multi-disciplinary scientists to allow for collaborative work across approximately 30 diverse field sites and the biomedical, social, and physical sciences, focusing on boundaries encountered and solutions developed. She will also describe uses for the short, easily implementable scale that has resulted from this collaboration. These uses include the ability to inform policy by measuring the impact of water security interventions and identifying the most water-insecure populations. The ability to measure household food insecurity has been transformative for research, policy, and humanitarian aid efforts; an analogous measure for water insecurity should be similarly impactful.
