The Scars of War: The Demonic Mother as a Conduit for Expressing Victimization, Collective Guilt, and Forgiveness in Postwar Japanese Film, 1949-1964
Date: 2017-05-01
Creator: Sophia Walker
Access: Open access
- Contemporary American viewers are familiar with the vengeful and terrifying ghost women of recent J-Horror films such as Ringu (Nakata Hideo, 1998) and Ju-On (Shimizu Takashi, 2002). Yet in Japanese theater and literature, the threatening ghost woman has a long history, beginning with the neglected Lady Rokujo in Lady Murasaki’s 11th century novel The Tale of Genji, who possesses and kills her rivals. Throughout history, the Japanese ghost mother is hideous and pitiful, worthy of fear as well as sympathy, traits that authors and filmmakers across the centuries have exploited. This project puts together four films that have never before been discussed together -- Kinoshita Keisuke's Shinsaku Yotsuya Kaidan (1949), Nakagawa Nobuo's Tokaido Yotsuya Kaidan (1959) Mizoguchi Kenji's Ugetsu (1953), and Shindo Kaneto's Onibaba (1964) -- and discusses them as four different iterations of the demonic mother motif, presented as a projection of the Japanese collective’s postwar uncertainty over both the memory of suffering during World War II and the question of personal culpability.
Modeling Coupled Disease-Behavior Dynamics of SARS-CoV-2 Using Influence Networks

- SARS-CoV-2, the virus that causes COVID-19, has caused significant human morbidity and mortality since its emergence in late 2019. Not only have over three million people died, but humans have been forced to change their behavior in a variety of ways, including limiting their contacts, social distancing, and wearing masks. Early infectious disease models, like the classical SIR model by Kermack and McKendrick, do not account for differing contact structures and behavior. More recent work has demonstrated that contact structures and behavior can considerably impact disease dynamics. We construct a coupled disease-behavior dynamical model for SARS-CoV-2 by incorporating heterogeneous contact structures and decisions about masking. We use a contact network with household, work, and friend interactions to capture the variation in contact patterns. We allow decisions about masking to occur at a different time scale from disease spread which dramatically changes the masking dynamics. Drawing from the field of game theory, we construct an individual decision-making process that relies on perceived risk of infection, social influence, and individual resistance to masking. Through simulation, we find that social influence prevents masking, while perceived risk largely drives individuals to mask. Underlying contact structure also affects the number of people who mask. This model serves as a starting point for future work which could explore the relative importance of social influence and perceived risk in human decision-making.
The Congressional Database: Designing a Web Application Using an HCI Approach

Access: Open access
- The activities of the United States Senate are a topic of interest for researchers and concerned members of the public alike. Websites such as GovTrack and Congress.gov allow people to research specific bills among many other offerings. However, they have significant weaknesses regarding their ease of use and the way they organize and store data. The Congressional Database Project aims to provide an intuitive user experience navigating government data while storing the data in a consistent database. We approach this project from an HCI perspective in order to determine the best ways to improve the user experience. We have conducted a qualitative user study to test the effectiveness of our design and identify potential areas of improvement. This paper provides an in-depth overview of the design of the Congressional Database on the front end and back end. It then explains the methodology of our user study and discusses the implications of its findings.
Genetic Analysis of Adhesion Protein ELMO3 in Arabidopsis thaliana

Creator: Garrison Asper

- The Extracellular Matrix (ECM) between plant cells is vital for structure, development, and intercellular adhesion. A pectin rich layer in between cells, the middle lamella, is largely responsible for regulating the adhesive properties of adjacent plant cells. Homogalacturonan (HG) pectin, the most common, is synthesized in the Golgi and secreted into the ECM where it undergoes calcium crosslinking, increasing its adhesive properties. Mutations in proteins essential for HG synthesis can reveal a severe adhesion defective phenotype, where the hypocotyls of dark grown Arabidopsis exhibit cell sloughing, curling, and general disorganization. A family of five ELMO proteins are suspected to act as scaffolds for pectin biosynthesis enzymes. ELMO1 and ELMO4 mutants exhibit an adhesion deficient phenotype, and a double mutant provides evidence of redundancy in function between ELMO1 and ELMO2. ELMO1-GFP co-immunoprecipitated with enzymes required for HG synthesis indicating its role as a scaffold protein. Double mutants of the other ELMO homologues were created to determine if they exhibit functional redundancy, and ELMO1 and ELMO3 appear partially redundant. A gene deletion of ELMO3 was also created using the CRSPR/Cas9 system, resulting in two distinct elmo3 deletion alleles, which were phenotypically identical to the original elmo3-/- mutant. All adhesion defective phenotypes can be partially suppressed by altering the osmoticum and hence turgor that provides pressure on adhesive cells. Lastly, ELMO3-GFP was localized to the Golgi, the site of pectin biosynthesis, further supporting a common role of the ELMOs in pectin biosynthesis.
