In the past, a person\u2019s political outlook was not a particularly reliable predictor of whether they would participate in surveys. Now it is. Polling organizations are implementing numerous strategies to combat this challenge. This presentation covers the nonresponse challenge from the perspective of Pew Research Center, a national nonpartisan polling organization. The talk will present data on the scope of the challenge in Pew polling, which includes an address-based-recruited panel and an annual multimodal cross-sectional survey. It will also cover novel ways that Pew is trying to reduce nonresponse bias.\r\n\r\nBio\r\nCourtney Kennedy is Vice President of Methods and Innovation at Pew Research Center. She supervises the Center\u2019s survey design and data science teams. Her research focuses on nonresponse, weighting, modes of administration and sampling frames. Kennedy has a doctorate from the University of Michigan and a master\u2019s degree from the University of Maryland, both in survey methodology. She received bachelor\u2019s degrees from the University of Michigan in statistics and political science.", "occurrence_notes":null, "guid":"134643-21874657@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134643", "building_id":"1000145", "building_name":"Institute For Social Research", "campus_maps_id":"76", "room":"1430BD", "location_name":"Institute For Social Research", "has_livestream":1, "livestream_type":"zoom", "livetream_require_login":0, "livestream_id":"96808884937", "livestream_password":"177406", "livestream_link":"https:\/\/umich.zoom.us\/j\/96808884937", "cost":"", "tags":["Survey Methodology"], "website":"https:\/\/src.isr.umich.edu\/", "sponsors":[ { "group_name":"Survey Research Center", "group_id":"5063", "website":"https:\/\/src.isr.umich.edu\/" }, { "group_name":"Institute for Social Research", "group_id":"3285", "website":"http:\/\/isr.umich.edu" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/04\/event_134643_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/04\/event_134643_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/04\/event_134643_original-1.png" }, "occurrence_count":1, "first_occurrence":21874657 } , "134990-21875894": { "datetime_modified":"20250414T130623", "datetime_start":"20250429T160000", "datetime_end":"20250429T170000", "has_end_time":1, "date_start":"2025-04-29", "date_end":"2025-04-29", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"CM-AMO Seminar | Bose-Einstein condensation of dipolar molecules", "occurrence_title":"", "combined_title":"CM-AMO Seminar | Bose-Einstein condensation of dipolar molecules: Sebastian Will (Columbia University)", "event_subtitle":"Sebastian Will (Columbia University)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Recently, we have created the first BECs of dipolar molecules [1,2]. We evaporatively cool a gas of sodium-cesium molecules to below 10 nanokelvin, deep in the quantum degenerate regime. The BECs live for several seconds. This dramatic improvement over previous attempts to cool molecules is enabled by collisional shielding via microwave dressing, suppressing inelastic losses by four orders of magnitude. We also observe that microwave dressing provides an exceptional level of tunability of dipole-dipole interactions, enabling novel phases of matter in molecular quantum liquids. \r\n\r\nIn this talk, I will discuss our experimental approach, share latest insights, and give an outlook on novel opportunities enabled by molecular BECs for many-body quantum physics, quantum simulation, and quantum computing. In addition, I will give a brief overview of our broader efforts in quantum. These include recent advances on single atom trapping in metasurface optical tweezer arrays [3] and our collaborative efforts with Brookhaven National Lab to realize a quantum network in the greater New York area.\r\n\r\nReferences:\r\n[1] \tBigagli, Yuan, Zhang, et al., Observation of Bose-Einstein condensation of dipolar molecules, Nature 631, 289-293 (2024)\r\n[2] \tBigagli, et al., Collisionally stable gas of bosonic dipolar ground state molecules, Nature Physics 19, 1579-1584 (2023)\r\n[3]\tHolman, Xu, et al., Trapping of single atoms in metasurface optical tweezer arrays, arXiv:2411.05321 (2024) \r\n\r\nBio:\r\nSebastian Will is a professor of physics at Columbia University.
