Using a new dataset of over 24,000 historical texts from 1000 to 1900, we measure regional exposure with two indicators: the frequency of core concepts and the count of associated authors. We also introduce a semantic similarity measure that compares local texts to Wang Yangming\u2019s writings. A difference-in-differences design exploiting the staggered introduction of public lectures shows that exposure rises after a prefecture\u2019s first lecture, with effects that persist in subsequent cohorts. Prefectures with higher exposure were more likely to produce reformist leaders in the Donglin Movement (1604\u20131627). Under the Qing (1644\u20131911), public lecturing was curtailed and the intellectual agenda shifted, so the lecture channel that helped seed Yangming learning in the Ming largely disappears from the record. Using contemporary survey data from 2010, we nevertheless find that detectable traces remain: residents in historically exposed prefectures express stronger support for the right to discuss public affairs and for limiting government involvement in private affairs. Together, the results link Yangming learning to reformist mobilization among elites and to long-run variation in attitudes toward political voice and the appropriate scope of government.", "occurrence_notes":null, "guid":"143569-21893396@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143569", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["Economics","History","Development","seminar"], "website":"http:\/\/www.lsa.umich.edu\/econ", "sponsors":[ { "group_name":"Department of Economics", "group_id":"3302", "website":"http:\/\/www.lsa.umich.edu\/econ" }, { "group_name":"Economic History", "group_id":"3549", "website":"" }, { "group_name":"Economic Development Seminar", "group_id":"3557", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/02\/event_143569_original-2.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/02\/event_143569_original-2.jpg" }, "occurrence_count":1, "first_occurrence":21893396 } , "145951-21898173": { "datetime_modified":"20260317T142055", "datetime_start":"20260317T143000", "datetime_end":"20260317T153000", "has_end_time":1, "date_start":"2026-03-17", "date_end":"2026-03-17", "time_start":"14:30:00", "time_end":"15:30:00", "time_zone":"America\/Detroit", "event_title":"Lucky Bingo", "occurrence_title":"", "combined_title":"Lucky Bingo", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Feeling lucky?

Yet, how federally funded engineering workforce development (EWD) programs define, differentiate, and communicate the value of engineering and technical roles remains underexamined. Positioned within engineering education research that examines pathways, professional formation, and the education\u2013workforce interface, this study investigates how a national, federally supported EWD initiative constructs and portrays engineering and technical occupational roles through its public-facing program materials and leader narratives. Drawing on qualitative document analysis and semi-structured interviews within an embedded qualitative case study of a national EWD initiative, the study applies a sociocultural value-systems lens to examine how patterned beliefs about knowledge, skill, and expertise are enacted at the programmatic and organizational level. Findings reveal consistent distinctions in how roles are framed across dimensions of work, worker, and occupation, with implications for engineering pathways, learner identity formation, and program alignment across educational and workforce contexts. By foregrounding the often-overlooked roles of technologists and technicians, this work contributes new empirical insight to engineering education scholarship and extends EER conversations beyond degree-centric models to include federally supported workforce pathways relevant to contemporary manufacturing practice.\n\nBiography: Winifred Opoku is a doctoral candidate in Engineering Education at The Ohio State University.

They couple strongly to each other and to external fields. The former enables controllable atom-atom, atom-photon and even photon-photon interactions, while the latter promises exceptionally sensitive and broadband microwave (MW) and radio frequency (RF) sensing capabilities. Typically, the Rydberg-Rydberg interactions are leveraged as a blockade mechanism. In contrast, we explore the antiblockade regime in atom arrays, where interactions facilitate rather than suppress excitation. I will present our numerical studies demonstrating directional quantum information and entanglement transfer [1], as well as robust avalanche amplification for weak signal detection [2]. For atom-field coupling, I will present our experimental work expanding MW sensing capabilities with cold atomic ensembles. First, we demonstrate 3D field characterization via multi-parameter extraction, which holds potential as a testbed for machine-learning-enhanced measurement protocols and has broad implications for information extraction from complex measurements. Second, we address the intersection of atom-atom and atom-field interactions by investigating the role of nonlinear atomic interactions in probing external fields [3]. Together, these studies show how tailoring Rydberg interactions expands the accessible measurement and dynamical capabilities of cold-atom platforms.\n \nReferences:\n[1] Yupeng Wang, Junjie Wang, Aishik Panja, Xinghan Wang, Qi-Yu Liang, \u201cDirectional Transport in Rydberg Atom Arrays via Kinetic Constraints and Temporal Modulation\u201d, Phys.

We will also discuss new and ongoing research associated with opportunities afforded by these performance gains.", "occurrence_notes":null, "guid":"145352-21897161@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145352", "building_id":"", "building_name":"", "campus_maps_id":"", "room":"1360", "location_name":null, "has_livestream":0, "cost":"", "tags":["Applied Mathematics","Mathematics"], "website":"https:\/\/www.sandia.gov\/ccr\/staff\/peter-andrew-bosler\/", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" }, { "group_name":"MCAIM - Department of Mathematics", "group_id":"4897", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/02\/event_145352_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/02\/event_145352_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21897161 } }
