Kelly, Carly Shinners, and Katherine Zoroufy Inspired by the cover image of San Diego, a favorite and the 2018 site of the Joint Mathematics Meetings, we indulge ourselves in the JMM Program (page 1067), read more about the AMS Short Course lecture topics (page 1016), make plans to attend, and make sure our memberships are up to date. We enjoy articles by Jessica Sidman and Audrey St. John on “The Rigidity of Frameworks” and by Catherine Bandle on “Dido's Problem.” We mull over opinion pieces, including a cautionary tale about a proposal to avoid election district ger- rymandering, which may come before the Supreme Court this month. We thank Susan Kelly, Carly Shinners, and Katherine Zoroufy for providing the story of Euphemia Lofton Haynes, the first African American woman to receive a PhD in mathematics. —Frank Morgan, Editor-in-Chief COMMENTARY GRADUATE STUDENT SECTION 986 Opinion: Ensuring that Mathematics is Relevant 1005 Evelyn Lamb Interview in a World of Data Science Alexander Diaz-Lopez Johanna S.

The Rigidity of Frameworks: Theory and Applications Jessica Sidman and Audrey St. John Communicated by Benjamin Braun icture a swarm of robots flying to move a piece of rubble from a disaster site, an engineer design- ing the roof of a stadium, or a protein docking an inhibiting drug. What these scenarios, pulled Pfrom robotics, computer-aided design (CAD), and structural biology, have in common is that each is gov- erned by a finite system of geometric constraints that can be analyzed using ideas from rigidity theory.

    Reimagining Revolutionary Labor in the People’s Commune: Amateurism and Social Reproduction in the Maoist Countryside by Angie Baecker A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Asian Languages and Cultures) in the University of Michigan 2020 Doctoral Committee: Professor Xiaobing Tang, Co-Chair, Chinese University of Hong Kong Associate Professor Emily Wilcox, Co-Chair Professor Geoff Eley Professor Rebecca Karl, New York University Associate Professor Youngju Ryu Angie Baecker [email protected] ORCID iD: 0000-0003-0182-0257 © Angie Baecker 2020 Dedication This dissertation is dedicated to my grandmother, Chang-chang Feng 馮張章 (1921– 2016). In her life, she chose for herself the penname Zhang Yuhuan 張宇寰. She remains my guiding star. ii Acknowledgements Nobody writes a dissertation alone, and many people’s labor has facilitated my own. My scholarship has been borne by a great many networks of support, both formal and informal, and indeed it would go against the principles of my work to believe that I have been able to come this far all on my own. Many of the people and systems that have enabled me to complete my dissertation remain invisible to me, and I will only ever be able to make a partial account of all of the support I have received, which is as follows: Thanks go first to the members of my committee. To Xiaobing Tang, I am grateful above all for believing in me. Texts that we have read together in numerous courses and conversations remain cornerstones of my thinking. He has always greeted my most ambitious arguments with enthusiasm, and has pushed me to reach for higher levels of achievement.

    CINEMATIC REALISM AND INDEPENDENT FILMMAKING IN CHINA by MEI YANG A DISSERTATION Presented to the Department of East Asian Languages and Literatures and the Graduate School of the University of Oregon in partial fulfillment of the requirements for the degree of Doctor of Philosophy June 2011 DISSERTATION APPROVAL PAGE Student: Mei Yang Title: Cinematic Realism and Independent Filmmaking in China This dissertation has been accepted and approved in partial fulfillment of the requirements for the Doctor of Philosophy degree in the Department of East Asian Languages and Literatures by: Alison M. Groppe Chairperson Tze-Lan Sang Member Alisa D. Freedman Member David Li Outside Member and Richard Linton Vice President for Research and Graduate Studies/Dean of the Graduate School Original approval signatures are on file with the University of Oregon Graduate School. Degree awarded June 2011 ii © 2011 Mei Yang iii DISSERTATION ABSTRACT Mei Yang Doctor of Philosophy Department of East Asian Languages and Literatures June 2011 Title: Cinematic Realism and Independent Filmmaking in China Approved: _______________________________________________ Dr. Alison M. Groppe Independent filmmaking in China, with the directors’ reiteration of literary and cinematic realism carried on from May Fourth, reflects the nation’s social uneasiness triggered by the enlarging division between the enlightenment indenture and the unidirectional modernization project. Resisting the national allegories and Hollywood-style big budget fantasies made by the Fifth Generation, independent filmmakers bring back to the screen the unadorned life of city inhabitants. The meaning of “independent” and “alternative” does not exclusively lie in the production and distribution venues but is galvanized by film directors’ perception and cinematic depiction of what constitutes the social realities of contemporary China.
