Presentation:Psychology Methods Hour: Power Analysis Has Lost Its Way: New Methods To Bring It Back Home
2025-02-14 09:00 - 10:00 (America/Detroit) | East Hall - 4448
In a time when the alarms of research replicability are sounding louder than ever, mapping out studies with statistical and inferential integrity is of paramount importance. Indeed, funding agencies almost always require grant applicants to present compelling a priori power analyses to justify proposed sample sizes, in an effort to ensure a sound investment. Unfortunately, even researchers’ most sincere attempts at sample size planning are fraught with the fundamental challenge of setting numerical values not just for the focal parameters for which statistical tests are planned, but for each of the model’s 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 adopt 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 greatly simplify that process. Derivations and suggestions for practice are presented using the framework of measured 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.

Exhibition:Red Summer: Racial Violence in the American Landscape, 1917-1923
2025-02-14 09:00 - 16:30 | East Quadrangle - RC Art Gallery
The Red Summer portfolio represents the stories of various locations in the American landscape where racial violence (often characterized as “Race Wars” at the time) erupted between 1917 and 1923. 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 “Red Summer” was first used by James Weldon Johnson to describe the violent attacks against black communities during 1919.

Though 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.

The 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.

Exhibition:Redefining the Crown
2025-02-14 09:00 - 16:00 | Lane Hall
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.

Based 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.

Through 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.

The 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.

Located on the first floor of Lane Hall (204 S. State Street), the Exhibit Space is free and open to the public, M-F, 9am-4pm.
