Indeed, funding agencies almost always require grant applicants to present compelling\u00a0a priori\u00a0power analyses to justify proposed sample sizes, in an effort to ensure a sound investment. Unfortunately,\u00a0even researchers\u2019 most sincere attempts at sample size planning are fraught with the fundamental challenge of\u00a0setting numerical values not just for the focal parameters for which statistical tests are planned, but for each of the model\u2019s other more peripheral or contextual parameters as well. As we plainly demonstrate, regarding the latter parameters, even in very simple models well-intentioned numerical guesses that are even slightly off can undermine power for the assessment of the more focal parameters that are of key theoretical interest. Toward remedying this all-too-common but seemingly underestimated problem in power analysis, we\u00a0adopt a hope-for-the-best-but-plan-for-the-worst mindset and present new methods that attempt (1) to restore appropriate conservatism and robustness, and in turn credibility, to the sample size planning process, and (2) to\u00a0greatly\u00a0simplify that process. Derivations and suggestions for practice are presented using the framework of\u00a0measured variable path analysis models as they subsume many of the types of models (e.g., multiple linear regression, ANOVA) for which sample size planning is of interest.", "occurrence_notes":"A reception will be held after the talk on the 3rd Floor Terrace, East Hall", "guid":"130715-21866571@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/130715", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4448", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["colloquium"], "website":"", "sponsors":[ { "group_name":"Department of Psychology", "group_id":"3615", "website":"http:\/\/www.lsa.umich.edu\/psych\/" }, { "group_name":"Psychology Methods Hour", "group_id":"3935", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/01\/event_130715_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21866571 } , "131383-21868358": { "datetime_modified":"20250117T144257", "datetime_start":"20250214T090000", "datetime_end":"20250214T163000", "has_end_time":1, "date_start":"2025-02-14", "date_end":"2025-02-14", "time_start":"09:00:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"Red Summer: Racial Violence in the American Landscape, 1917-1923", "occurrence_title":"", "combined_title":"Red Summer: Racial Violence in the American Landscape, 1917-1923: Wendel A.

These years of conflict reveal several aspects of racial anxiety that inform our contemporary experience, including, though not limited to; racism, fear of violent black revolt, lynching, poverty, mass incarceration, and competition for employment. The term \u201cRed Summer\u201d was first used by James Weldon Johnson to describe the violent attacks against black communities during 1919. \r\n\r\nThough the events of the early twentieth century seem to be remote and fading apparitions of an American past; my work is concerned with the power and influence of our shared historical narrative upon the present. The upheaval of Red Summer occurred approximately fifty years after the American Civil War, fifty years before the height of the Civil Rights Era, and three centuries after the first enslaved Africans arrived in English colonies that would become the United States. \r\n\r\nThe project combines photographs of the contemporary landscape made at or near the site of racial conflict with fragmented selections of contemporaneous newspaper reporting (1917-1923). In many cases, the newsprint images include the surrounding stories or advertisements. The combination of the landscape photograph and the reproduction of newspaper fragments (which invade the contemporary with a narrative from the past), is a rupture and a conversation on the timeline between past and present.", "occurrence_notes":"Enter through East University Ave. Open to the public.", "guid":"131383-21868358@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/131383", "building_id":"1000054", "building_name":"East Quadrangle", "campus_maps_id":"54", "room":"RC Art Gallery", "location_name":"East Quadrangle", "has_livestream":0, "cost":"", "tags":["Visual Arts","Ann Arbor","Art","artists","arts","arts at michigan","Exhibition","free"], "website":"https:\/\/lsa.umich.edu\/rc\/reserve-a-room-\/rc-art-gallery.html", "sponsors":[ { "group_name":"Residential College", "group_id":"1029", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/01\/event_131383_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/01\/crop-event_131383_original-1.png" }, "occurrence_count":34, "first_occurrence":21868321 } , "129602-21864042": { "datetime_modified":"20250211T122734", "datetime_start":"20250214T090000", "datetime_end":"20250214T160000", "has_end_time":1, "date_start":"2025-02-14", "date_end":"2025-02-14", "time_start":"09:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Redefining the Crown", "occurrence_title":"", "combined_title":"Redefining the Crown: The Voices of Black Breast Cancer Survivors", "event_subtitle":"The Voices of Black Breast Cancer Survivors", "event_type":"Exhibition", "event_type_id":"7", "description":"In Winter 2025, the Lane Hall exhibit space will feature a portraiture series titled Redefining the Crown showcasing the powerful stories of six Black breast cancer survivors.\r\n\r\nBased on a photo essay by U-M Faculty Versha Pleasant (MD\/MPH) and Ava Purkiss (PhD) in Medicine at Michigan, this exhibition examines the cultural and personal significance of hair within Black communities, particularly through the lens of breast cancer treatment and recovery. The term \"crown\" is deeply symbolic in Black culture, signifying beauty, strength, and identity. The featured photo essay by photographer Tafari Stevenson-Howard captures the intimate journeys of Ann Chatman, Tanisha Kennedy, Felecia McDaniel, Shantell Elaine McCoy, Tamara Lynn Myles, and Veleria Banks.\r\n\r\nThrough their narratives and portraits, the exhibit examines how these women have navigated the profound impact of hair loss caused by chemotherapy, inviting the audience to witness their stories with radical empathy. It explores the cultural pride and personal identity intricately tied to their hair, and how these elements are redefined amidst their battles with breast cancer.\r\n\r\nThe exhibit will be on view from January 21, 2025 to August 8, 2025. This exhibition is presented with support from IRWG, the Department of Women's and Gender Studies, and Michigan Medicine. \r\n\r\nLocated on the first floor of Lane Hall (204 S.
