Differences In Internalized Weight Bias Across Eating Disorder Treatment Groups, Kathryn Bick

University of Montana Conference on Undergraduate Research (UMCUR)

Internalized weight bias (IWB) is characterized as the extent to which someone holds stigmatizing attitudes about themselves based on social stereotypes and their perceived weight status. IWB is positively associated with increased disordered eating and adverse mental and physical health outcomes. Moreover, those with eating disorders (EDs) often experience elevated levels of IWB due to societal weight stigma and subsequent preoccupations with body and shape. While the relationship between IWB and eating pathology is relevant across ED diagnoses, and across the weight spectrum, its specific influence on the development and maintenance of an eating disorder is understudied. Current eating disorder …

Fighting For The Franchise: African American Disfranchisement In Charlottesville, Virginia, Thomas R. Seabrook

Madison Historical Review

Around the turn of the twentieth century, white Southerners crossed the political aisle to disfranchise African American voters through a series of legislation at the state level. Though African Americans resisted these efforts to strip them of their citizenship rights, many historians believe that African Americans had been practically shut out of politics by 1900. Disfranchisement did not mean that African Americans stopped asserting their constitutional rights, however, as historians who trace African American organization and resistance have shown. In this article, I examine the response of African Americans in Charlottesville, Virginia, to disfranchisement and I consider the effect disfranchisement …

The Necessary Bargain: How Texas Education Utilized President Johnson’S Elementary And Secondary Education Act, 1965-1970, Kade L. Kahanek

Madison Historical Review

President Lyndon Johnson announced his “War on Poverty” campaign at the State of the Union Address in January 1964. Johnson’s address acknowledged that United States citizens suffered from poverty in many regions and enclosed a plan to relieve poverty in America. President Johnson’s administration administered “Great Society” programs under education, healthcare, and the job corps to help ease the burdening symptoms of poverty. It has been long debated whether Johnson’s policies to improve America’s society have succeeded, but many fail to recognize that his education plan was the centerpiece and perhaps not an instant cure to poverty; instead, something concrete …

Republican Manhood And The Disabled Revolutionary War Veteran In The Early American Republic, 1789 – 1797, Virgil Clark

Madison Historical Review

In the aftermath of the American Revolutionary War, several Disabled Continental Army soldiers scattered across the burgeoning Republic were driven by desperation to write letters, pleading with General George Washington for his support. The soldiers’ decision to draft these letters stemmed from their profound frustration and disillusionment with the post-Revolution American state. The soldiers' discontent resulted from the sense of neglect they experienced after the state rejected their petitions for a Disabled Veteran’s pension. As time passed and rent went unpaid, medical bills piled up, and the threat of vagrancy loomed over these men like a malevolent specter. Unable to …
