This project comprises qualitative public health research conducted in impacted communities and visual arts generated from the research outcomes. Research teams of graduate and undergraduate students from the University of Michigan, led by Professor William Lopez, and the University of Iowa, led by Professor Nicole Novak, collaborated with a range of community members and organizers at sites of six large-scale immigration worksite raids that occurred in 2018 in Iowa, Nebraska, Ohio, Tennessee, and Texas. The researchers visited these sites, spoke to advocates, detainees, their families, and other community members. In conversation with the seventy-seven interviews, artists Dalia Harris and Carolina Jones Ortiz generated ten images that comprise ICE in the Heartland. On display with the artworks are community member testimonies, analysis on the public health detriments to immigration worksite raids and deportation, insights to the artists\u2019 methods, and the curricular materials used in public outreach programs. \r\n\r\nHosted and sponsored by the Institute for Research on Women and Gender and the Department of Women\u2019s and Gender Studies, U-M.", "occurrence_notes":null, "guid":"139065-21884763@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/139065", "building_id":"1000183", "building_name":"Lane Hall", "campus_maps_id":"84", "room":"Lane Hall Exhibit Space--First Floor", "location_name":"Lane Hall", "has_livestream":0, "cost":"", "tags":["Storytelling","Art","advocacy","Activism","Visual Arts","Education","social justice","social inequality","research","public health","irwg","immigration","institute for research on women and gender","Inequality","Human Rights","free","Exhibition"], "website":"http:\/\/irwg.umich.edu\/", "sponsors":[ { "group_name":"Institute for Research on Women and Gender", "group_id":"1031", "website":"http:\/\/irwg.umich.edu\/" }, { "group_name":"Women's and Gender Studies Department", "group_id":"2809", "website":"http:\/\/www.lsa.umich.edu\/wgs" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/09\/event_139065_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/09\/event_139065_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/09\/event_139065_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/09\/event_139065_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/09\/event_139065_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/09\/event_139065_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/09\/event_139065_original-1.png" }, "occurrence_count":84, "first_occurrence":21884714 } , "137103-21879602": { "datetime_modified":"20250806T172347", "datetime_start":"20251031T090000", "datetime_end":"20251031T200000", "has_end_time":1, "date_start":"2025-10-31", "date_end":"2025-10-31", "time_start":"09:00:00", "time_end":"20:00:00", "time_zone":"America\/Detroit", "event_title":"Suave Mechanicals: A Celebration of Nine Volumes on the Art and History of Bookbinding (2013\u20132025)", "occurrence_title":"", "combined_title":"Suave Mechanicals: A Celebration of Nine Volumes on the Art and History of Bookbinding (2013\u20132025)", "event_subtitle":"", "event_type":"Exhibition", "event_type_id":"7", "description":"Explore the art of judging\u00a0books by their covers!\u00a0This exhibit highlights a selection of rare books from the University of Michigan's collections, each of them representing binding topics featured in \"Suave Mechanicals,\"\u00a0the acclaimed nine-volume series dedicated to the study of the art and history of bookbinding. \r\n\r\nSpanning from 2013 to 2025, \"Suave Mechanicals\"\u00a0contains 85 essays, 27 of which examine the same type of binding as the artifacts on display.

Through simulations of past warm climates, we can measure shifts in temperature, the hydrological cycle, or the carbon cycle that may offer insights into modern warming trajectories and model biases. This dissertation examines changes in atmospheric and marine processes in response to warming across novel simulations of past climates with environmental proxy data to further understand the Earth system under elevated CO2 levels.\r\n\r\nIn Chapter 2, we investigate the orbital sensitivity of Earth\u2019s hydrological cycle under different CO2 background states within an Early Eocene setting by conducting water isotope-enabled Community Earth System Model (CESM) simulations at 3x and 6x pre-industrial (PI) CO2 levels. This chapter suggests that seasonal hydrological responses to orbital changes are greater than CO2-driven changes in several regions \u2013 with these orbital differences more pronounced in lower CO2 climates \u2013 and, therefore, the orbit in place during proxy archive formation can provide critical context for interpreting oxygen isotopic signals.\r\n\r\nIn Chapter 3, we explore equilibrium climate sensitivity (ECS) across CESM slab ocean model (SOM) simulations of four distinct past climate intervals: the late Cretaceous (~90 Ma), the early Eocene (~55 Ma), the late Oligocene (~25 Ma), and PI. We analyze the contributions of model boundary conditions, like CO2 state, geography, and ocean heat transport (OHT), to ECS differences and decompose the total climate feedback parameter in order to provide new constraints on ECS sensitivity and variability through Earth\u2019s history. \r\n\r\nIn Chapter 4, we simulate the Miocene Climatic Optimum (MCO) at pre-MCO 280 ppm CO2 and MCO 560 ppm CO2 levels using CESM coupled with the Marine Biogeochemistry Library (MARBL) to study phytoplankton community structure and marine primary productivity shifts during this recent warm period. We find that an elevated CO2 level leads to surface warming, sea ice melt, weakened overturning, inhibited upwelling, and changes in nutrient distribution. These consequences result in poleward migration and increased productivity by small phytoplankton and decreased productivity by larger diatoms.\r\n\r\nTogether, the results of this dissertation demonstrate the value of advanced ESM simulations, particularly when analyzed alongside empirical data, in determining potential hydrological, radiative, or biogeochemical alterations in response to elevated atmospheric CO2 concentrations throughout Earth\u2019s history.", "occurrence_notes":null, "guid":"141182-21888303@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141182", "building_id":"1000188", "building_name":"1100 North University Building", "campus_maps_id":"628", "room":"2540", "location_name":"1100 North University Building", "has_livestream":0, "cost":"", "tags":["Earth And Environmental Sciences"], "website":"", "sponsors":[ { "group_name":"Earth and Environmental Sciences", "group_id":"3170", "website":"http:\/\/www.lsa.umich.edu\/earth" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/10\/event_141182_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/10\/event_141182_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21888303 } }
