SUMMARY:Workshop / Seminar:RCGD Fall Seminar Series: Global Perspectives on Culture and Health (Emily M. Briceño)
DESCRIPTION:RCGD Fall 2026 Seminar Series: Global Perspectives on Culture & Health\, meets Mondays 3:30 to 5 at ISR Thompson 6050.\n\nGlobal Perspectives on Culture and Health explores fundamental aspects of human life. Culture facilitates human interaction by providing meaning to lived experience. Accounting for culture in both theories and methods potentially advances the study of health by connecting the macro and micro levels of human experience. Yet\, culture should be understood as dynamic and complex. It fundamentally shapes individuals and simultaneously is shaped by individuals. The importance of systematically attending to culture includes topics of values\, language\, immigration\, and society.\n\nTheories and methods that incorporate culture hold great potential for advancing the understanding of health outcomes and health trajectories in various global contexts.\n\nThe speakers for this series will focus on various aspects of culture and diverse groups living in the U.S. and across the globe to address the ways in which attending to culture helps clarify and overcome challenges to good health.\n\nThe Group Dynamics Seminar series is considered one of the longest running seminar series in the social sciences. It has been running uninterruptedly since it was founded by Kurt Lewin in the 1920’s in Berlin. The seminar series runs every semester on a theme chosen by faculty organizer/s who are affiliated with the Research Center for Group Dynamics at the Institute for Social Research. A very important feature of this seminar today is its interdisciplinary nature. Recent themes have included political polarization\, evolution and human behavior\, and cultural psychology.\n\nIn person: ISR Thompson 6050\, unless otherwise specified.\nOrganized by Kristine Ajrouch and Sela Panapasa\nEvents are not recorded.

SUMMARY:Lecture / Discussion:Depressed Mothers and Rebellious Sons: Relationships in the History of American Mood Disorders
DESCRIPTION:The formal diagnosis of adult major depressive disorder emerged in the 1970s in the context of research with medication\, though disagreement about whether children could experience depression was not resolved until the 1980s and 1990s. 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). She is editor-in-chief of the Journal of the History of Medicine and Allied Sciences.

SUMMARY:Lecture / Discussion:Dynamics Seminar: Yet another unstabilizable rational surface map
DESCRIPTION:I will discuss a newly identified example of a plane rational map that has constant Jacobian determinant relative to the natural holomorphic volume form on the algebraic torus.  A distinguishing feature is that it `tropicalizes' as a self-map of the circle that is topologically conjugate to angle doubling.  Using this and post-composing with an appropriate monomial map we get a new and rather different example of a rational surface map that is not birationally conjugate to any algebraically stable map.  This work\, joint with Chase Bender and Holly Krieger\, relies on some AI input\, but maybe not where you'd guess it does.

SUMMARY:Workshop / Seminar:Easy to Collect\, Costly to Bear: Mobile Money Taxation and  Network Spillovers in Tanzania
DESCRIPTION:This paper provides evidence that a tax on mobile money transactions shrinks its base by an order of magnitude more than taxes on income or turnover do\, that the base responds to whether it is taxed rather than to how much\, and that the damage spreads through the payment network to users and payments the law never taxed. First\, using the complete transaction records of Tanzania’s 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.

SUMMARY:Workshop / Seminar:GLNT: Modular Character Sheaves and Monodromic Hecke Categories
DESCRIPTION:Abstract:  Character sheaves provide a geometric framework for studying characters of finite groups of Lie type. Introduced by Lusztig in the 1980s\, they played a central role in the classification of irreducible complex representations of these groups and in the computation of their characters. Although the definition of character sheaves can be formulated with modular coefficients\, much of Lusztig's characteristic-zero machinery breaks down in this setting.\n\nIn this talk\, I will give a streamlined overview of the theory of character sheaves using modern language from categorical representation theory. From this perspective\, categorical traces allow one to study character sheaves through monodromic Hecke categories. I will describe two models for these categories: a geometric categorification in terms of parity sheaves and an algebraic categorification in terms of Soergel bimodules. A key advantage of these models is that they are tightly controlled by p-Kazhdan–Lusztig combinatorics. This paves the way for a more algebraic study of modular character sheaves.

SUMMARY:Workshop / Seminar:How plabic graphs describe weakly separated collections
DESCRIPTION:Two k-element subsets I\,J of {1\,2\,…\,n} are weakly separated if the sets I\J and J\I (when drawn on a circle with vertices 1\,2\,…\,n) can be separated by a chord. A maximal weakly separated collection is a set of pairwise weakly-separated k-element subsets of {1\,2\,…\,n} that is not contained in any larger set with this property. This definition gives rise to natural combinatorial questions: How big is a maximal weakly separated collection? How many are there? How are they related to each other?\n\nI will outline how Oh\, Posknikov\, Speyer answered most of these questions via a bijection between maximal weakly separated collections in a positroid and move-equivalent plabic graphs. Along the way\, we’ll meet some fun combinatorial objects related to plabic graphs including bounded affine permutations\, Grassmann necklaces\, positroids\, and plabic tilings.
