Many critics and scholars have interrogated the construction of psychiatric diagnosis in the United States. This talk will attend to the relationships that formed the backdrop in depression research, especially between depressed mothers and their rebellious sons. In the process of creating purportedly objective categories of illness, relationship dynamics were redefined as genetic propensity, while the brain was located as a value-neutral site, away from social context.\n\nLaura Hirshbein, MD, PhD is the George E Wantz MD Distinguished Professor of the History of Medicine at the University of Michigan. She is a professor in the Department of Psychiatry and director of the Program of the History of Medicine and Public Health within the Center for History, Humanities, the Arts, Social Sciences, and Ethics of Medicine (CHHASSEM).\n\nShe has published two books (American Melancholy in 2009 and Smoking Privileges in 2013), and her third book is forthcoming from Columbia University Press (Troubled).

First, using the complete transaction records of Tanzania\u2019s three largest providers around the introduction of a notched levy on person-to-person transfers and cash withdrawals in July 2021, we show that the levy reduces the volume of taxed transactions by 23 percent and their average value by 13 percent relative to untaxed transactions on the same platform, an elasticity with respect to the net-of-tax price of about 10. Second, we show that a cut of about 30 percent seven weeks later brings none of it back, nor do two further cuts, while the removal of the levy on transfers in 2023 does, slowly. Third, we document that relationships between senders and receivers survive at two-thirds the normal rate, that new ones form at less than half the pre-levy pace, and that senders stop rerouting activity around recipients who go quiet; none of these margins recovers when the tax rate falls. Fourth, we find that the levy reaches activity it does not tax, as wages paid into wallets fall by a fifth, and that senders of every size cut back by a similar share, whether or not they have a bank account. Fifth, we estimate that the levy destroys 47 cents of surplus for every shilling it raises, several times the cost of a value-added tax in comparable settings.", "occurrence_notes":"For those not
