Sunset Over Sunset: Exploring the Street-Level View of Postwar Urban Redevelopment Using Ed Ruscha’s Los Angeles Photography

SPONSOR:  National Endowment for the Humanities
AWARD DATE:  12/14/2020

The artist Ed Ruscha’s 1966 photographic book, Every Building on the Sunset Strip, depicted a continuous view of both sides of the famed street, shot from his truck. Less well-known are the images he created by repeating this drive every few years across Sunset. Sunset over Sunset is a collaborative project that will spatially organize and interpret the vast and unparalleled archive of Ruscha's Sunset Boulevard photographs, recently digitized by the Getty Research Institute, to gain new perspectives into the histories of urban development, photography, architecture, and planning. The project advances the digital humanities by building a replicable, open-source model for making street-level photographs and other address-based data sets broadly accessible as primary sources and by joining visual and non-visual evidence to create a novel resource for place-based research by scholars and the general public. This is a collaborative project with Francesca Ammon (University of Pennsylvania) and Garrett Dash Nelson (Leventhal Map & Education Center).

Visiting Faculty Fellowship

SPONSOR: CENTER FOR THE STUDY OF RACE AND ETHNICITY IN AMERICA, BROWN UNIVERSITY
AWARD DATE: 05/28/2021

During the fellowship period, Mani will work on a public-facing book on race, representation, and South Asian diasporic identity. This monograph investigates the relationship between photography and racial belonging, situating the family photograph as a social text that captures the intimate domestic as well as public historical dimensions of racialized citizenship among South Asians in diaspora. Taking as a starting point Mani's personal archive of photographs, mapping her family’s migration from India to Japan to the Middle East and United States across three generations, the book incorporates close readings of photographic images alongside oral histories of migration. Mani deploys the family album in order to reflect on what it means for racialized immigrants to create archives of self-representation.

Worms in the Garden: Bad Feelings in a Good Life

SPONSOR: NATIONAL HUMANITIES CENTER
AWARD DATE: 04/20/2021

Dr. Thomason will spend an academic year as the Philip L. Quinn Fellow at the National Humanities Center to complete her book, Worms in the Garden: Bad Feelings in a Good Life. Figures in the history of philosophy from Seneca to Śāntideva have warned about the damaging effects of negative emotions. Today, the burgeoning wellness industry offers apps and other tools for overcoming negativity. Worms in the Garden is an apology for bad feelings. Philosophers argue that our emotions are reflections of what we care about or what matters to us. Feeling compassion for others, for instance, shows that we care about their suffering. Dr. Thomason argues that negative emotions are no different: they show that we value ourselves. Human emotional life is like a complex ecosystem, and bad feelings are the worms. Ecosystems aren’t better off without their worms and neither are we. The trick is learning how to enjoy our gardens, worms and all.

Functional Analysis of Locus-Specific Pericentric Satellite Expression

SPONSOR: National Institutes of Health
AWARD DATE: 9/5/2019

The goal of this project is to understand the basic structure and function of specific DNA sequences found near chromosomal centromeres – constricted regions to which spindle fibers attach, enabling duplicated chromosomes to segregate to opposite poles of a dividing cell. Tandemly repeated DNA sequences reside within these regions of chromosomes and have been historically poorly studied due to difficulties in the genomic assembly of repetitive DNA sequences. In cancer cells, these repetitive sequences are misregulated such that they become expressed, and we aim to understand both their sequence diversity and consequences of their expression. The proposed project promises to engage and train undergraduate researchers in innovative genomics, cytological and proteomics techniques, which will propel future careers in genomics and biomedical research.

Elucidating the impact of the Npc1nmf164 mutation in the postnatal cerebellar development of a mouse mode of Niemann-Pick TypeC disease

Sponsor: Rowan University/National Institutes of Health
Award Date: 8/24/2018

Niemann-Pick type C (NPC) is an inherited lysosomal storage disease often caused by mutations in Npc1, a protein that exports cholesterol out of the lysosomes, resulting in abnormal accumulation of cholesterol and other lipids in endosomes and lysosomes.  NPC results in significant neurological symptoms, including ataxia, cognitive impairment, and dementia, that lead to premature death. Professor Carone’s preliminary research indicates cellular and structural changes in susceptible neurons and microglial cells are occurring during postnatal developmental stages and this study further explores how protein mutations related to NPC impact the cerebellum during the postnatal development stage.

RUI: Comparative analysis of endocytic trafficking during cell division

SPONSOR: NATIONAL SCIENCE FOUNDATION
AWARD DATE: 04/16/2021

This collaborative research project between Swarthmore, Colby College, and Princeton University explores the interplay between cell division and signals that cells exchange to coordinate their behavior. Signal-dependent coordination of cell behavior is essential for the growth of all life forms. Signaling also plays a crucial role in dividing stem cells. Errors in signaling are the primary cause of cancer. The combined expertise will enable comprehensive investigations of signaling in dividing cells using an array of organisms, along with cutting edge genetic manipulation and imaging technologies. Additionally, this collaboration will pursue an ambitious outreach program which will include the development of a class focused on cancer biology for elementary school students in an underserved school district as part of the established Science for Kids summer program at Swarthmore College and integration between Summer Scholars Programs at Colby, Princeton and Swarthmore which focus on preparing URM and other diverse students for a successful college transition.

EAGER: Exploration of evolutionary mechanisms across multiple scales


SPONSOR: NATIONAL SCIENCE FOUNDATION

AWARD DATE: 01/10/2021

This research project, funded by NSF’s Early-Concept Grant for Exploratory Research (EAGER) and in collaboration with the University of Florida and the University of Georgia, will address questions of evolution and embryonic development through the comparative study of two sea squirts (a group of marine organisms closely related to humans and other vertebrates). In particular, this research will focus on a very poorly characterized group of sea squirts called the doliolids. Doliolids have acquired a number of highly divergent traits including the ability to produce four distinct body types specifically designed for feeding, dispersal, aesexual reproduction or sexual reproduction. The relative simplicity of sea squirt genomes and the low number of cells in sea squirt embryos will facilitate rigorous analysis of the evolutionary acquisition of new traits across multiple biological scales. This project will also provide a diverse group of trainees, including those that identify with groups underrepresented in the biological sciences, the opportunity to participate in cutting-edge research spanning computational, molecular, cellular, developmental, ecological and evolutionary biology.

Dissecting the interactions and conformations of protein kinases to understand biochemical signaling

SPONSOR: RESEARCH CORPORATION FOR SCIENCE ADVANCEMENT
AWARD DATE: 02/19/2021

Protein kinases act as molecular on/off switches in the cell. They are important for intracellular communication and their functions vary from controlling cell growth and metabolism to controlling cell death. With funding from the Cottrell Scholars program, the proposed research will focus on a protein kinase, called Lyn, which is a critical regulator of the immune response. Researchers in both the Fera lab and in Prof. Fera’s biochemistry lab course will perform a molecular “dissection” of Lyn and its regulatory modules using approaches from structural biology, biochemistry, and biophysics, to understand what keeps Lyn “off” until triggered to turn “on”. This is important for understanding how the immune system acts against the correct targets, i.e. outside “invaders”, and how to modulate the pathways in cases in which they are deregulated and might cause autoimmune disease. The approaches used in these analyses will also provide a proof-of-concept for studying other dynamic molecules and how they interact with other macromolecules to get a wider view of signaling inside a cell. Through this work, students will engage in authentic research experiences, gain skills that will help them in future scientific endeavors, and make important contributions to science.

Analysis of the Initiation of an HIV Broadly Neutralizing Antibody Lineage in a Single Host

SPONSOR: NATIONAL INSTITUTES OF HEALTH
AWARD DATE: 03/23/2020

Human immunodeficiency virus (HIV) is a rapidly evolving pathogen that escapes immune defenses provided by most vaccine-induced antibodies. Proposed strategies to elicit broadly neutralizing antibodies (bnAbs) by vaccination require a deeper understanding of evolution of the immune response to infection, since these protective antibodies typically take ~4-5 years to develop. In HIV-infected individuals, viruses and antibody producing B-cells evolve together, creating a virus-antibody “arms race,” with populations of viruses and antibodies present throughout infection. This research will analyze critical early time-points of the arms race in a donor who developed antibodies of significant breadth, to guide immunogen design. Undergraduate research students supported by this Academic Research Enhancement Award (AREA) from the National Institute of Allergy and Infectious Diseases (NIAID) will explore an issue of critical public health importance using cutting-edge techniques, be co-authors on published work and be mentored by experts committed to their long-term career development.

Scar Detection and Treatment with Droplet Activation

SPONSOR: NATIONAL INSTITUTES OF HEALTH
AWARD DATE: 07/28/2020

The application of microbubbles to diagnostic and therapeutic modalities has been vast from tumor imaging to drug delivery to sonothrombolysis. The main limitations of microbubbles is their stability after venous administration as well as their size, which constrains them to the intravascular compartment. Recent development of phase-change agents (PCAs) has led to expanded applications of ultrasound contrast and movement into the extravascular space. In collaboration with the University of Nebraska Medical Center, Professor Everbach will provide cavitation monitoring and quantification for in-vitro studies of the effect of ultrasound on perfluorocarbon liquid droplets in a model (non-living) system.

RUI: Structural and Dynamical Specializations of Axons that Enhance Neural Coincidence Detection

SPONSOR: NATIONAL SCIENCE FOUNDATION
AWARD DATE: 03/11/2020

Mathematical research has led to essential insights into the dynamics of neurons and function of the brain. The long-term goals of our work are to create new mathematical methods that describe auditory centers in the brain and advance knowledge of the auditory system and hearing. In this Research in Undergraduate Institutions (RUI) project, we will study neurons in the auditory brainstem of mammals and birds that are essential components of how animals determine the locations of sound sources. We will develop mathematical theory to explain the biophysical and dynamical specializations of these coincidence detector neurons and also consider how hearing loss may degrade neural coincidence detection.  A central component of the project is the training of undergraduate students in computational neuroscience, a fast-growing field at the interface of mathematics and neuroscience.

Implementation of Item Response Theory to improve forensic proficiency testing

SPONSOR: NATIONAL INSTITUTE OF STANDARDS & TECHNOLOGY (NIST)
AWARD DATE: 07/10/2020

Fingerprints have been used as evidence in criminal cases for decades, and their probative value has been reaffirmed in countless legal decisions. Yet, in recent decades, questions have arisen about the accuracy with which an examiner can identify the source of a blurry, partial print, and about the probability of observing a match between two prints made by different fingers. One way to assess examiner performance in real criminal cases is through tests of examiner performance, e.g., proficiency tests or error rate studies. Although proficiency tests are widely used in forensic science for training and  procedural purposes, they are not being utilized to their full potential. This project proposes an industry-wide adoption of Item Response Theory (IRT), which is well-established in the field of educational testing, to improve forensic proficiency testing. This is a collaboration with the Center for Statistics and Applications in Forensic Evidence (CSAFE).

Where are the shocks in O Star Winds? Understanding constraints from f/i ratios in He-like ions

SPONSOR: SMITHSONIAN ASTROPHYSICAL OBSERVATORY
AWARD DATE: 02/16/2021

NASA's Chandra X-ray Observatory is a telescope designed to detect X-ray emission from very hot regions of the universe such as exploded stars, clusters of galaxies, and matter around black holes. The Chandra X-ray Center operates the satellite, processes the data, and distributes it to scientists around the world for analysis. The most massive and luminous stars in the Galaxy produce X-rays in their outflowing stellar winds. In this project, we will model the relative strengths of particular emission lines seen in Chandra spectra in order to determine the distance above the surface of the star at which the X-rays are produced. This will inform theories of the X-ray production itself. Undergraduate students will be significantly involved in this labor and data intensive effort, gaining important experience in x-ray astrophysics.

Heat Capacity and Enthalpy of Amorphous Materials

SPONSOR: AMERICAN CHEMICAL SOCIETY
AWARD DATE: 10/28/2020

Glasses are solids, like crystals, but isotropic and without long-range order, like liquids.  When an amorphous solid is heated, before crystallization occurs, the material softens, becoming a viscous liquid that is deeply undercooled below its usual melting temperature. Significant heat is absorbed in this “glass transition,” raising the entropy of the material with respect to its crystalline structure. Dr. Smith will lead an investigation of the heat capacity and enthalpy, together with the free energy and entropy, of glasses with diverse physical properties.  This project will use experimental tools to obtain a complete thermodynamic description of several glasses in their amorphous, crystalline, and supercooled liquid states.

RUI: Looking beyond LCDM—observational consequences of models that ease the Hubble tension

SPONSOR: NATIONAL SCIENCE FOUNDATION
AWARD DATE: 07/22/2020

Over the past twenty years, greater precision in cosmological measurements have revealed intriguing tensions that challenge the standard cosmological model. The most pressing of these is a disagreement between two distinct ways scientists estimate the current expansion rate of the universe (known as the Hubble constant). One estimate is based on direct measurement that uses observations of supernovae; the other is based on indirect measurement that uses observations of the afterglow of the big bang. Whereas the data from these two estimates used to agree, advances in measurement precision now yield values for the Hubble constant that are statistically different. This “Hubble tension” may be pointing scientists to new and unexpected physics not included in the standard cosmological model. This Research at Undergraduate Institutions (RUI) project will advance the field of cosmology by refining what this tension may signify about new and unanticipated physical processes and in doing so has the potential to enhance our understanding of the origin and evolution of the universe.

Exploring Fixed Costs in Female Hiring:  The Role of Adjustment Costs and Cultural Barriers to Women’s Employment

SPONSOR:  HARVARD KENNEDY SCHOOL
AWARD DATE:  08/22/2017

Saudi Arabia’s Nitaqat program has sharply increased female employment in the private sector.  However, hiring was not spread evenly across firms. Some have shown rapid growth in female employment; others have continued to employ only male workers.  This study will begin studying if this may be due to fixed costs. While hiring female workers may be attractive to firms trying to meet nationalization quotas, firms must first invest in the capacity to hire women. Workplace adjustments may also be needed to comply with cultural norms.  This pilot will gather information on firms’ assessments of these constraints through a combination of administrative data analysis, interviews, and a firm survey. While the focus will be on fixed costs, the evidence gathered as part of this study will likely shed light on the perceived barriers to hiring women, providing crucial evidence for future work on female labor force participation in the region.

Mastery-Oriented Professional Development for Integrating CS into Math

SPONSOR: NATIONAL SCIENCE FOUNDATION
AWARD DATE: 03/12/2021

Roughly half of the US states have adopted K-12 Computer Science (CS) standards to date. Many districts, however, cannot afford standalone CS classes. Integrating CS into existing courses is a promising alternative, but little research guides districts on how students learn CS in integrated contexts or how teachers gain confidence, interest, and skill to teach integrated computing content. Swarthmore College is a subaward partner institution in this collaboration with Brown University, Bootstrap, and the Oklahoma Department of Secondary Education. The award expands ongoing work to prepare 8th and 9th grade math teachers in Oklahoma to integrate computing more extensively. The mixed-methods research draws on surveys and longitudinal interviews with teachers, recordings of classrooms, samples of student work, and data on student assessments. This project is funded by the CS for All: Research and RPPs program.

SPONSOR:  THE SPENCER FOUNDATION
AWARD DATE:  04/11/2018

"The Listening Project" is a collaboration with New York University that will offer a new direction in research for a solution to the “crisis of connection" in today’s schools.  This research will specifically focus on the pivotal context of middle schools where this crisis starts to emerge. This work is rooted in our shared capacity to listen to one another so that we may understand, be understood, see, be seen, and care and cooperate across and within communities.  The team will train a sample of NYC middle school teachers and 7th grade students of color in the practice of "transformative interviewing" to enhance listening skills, build relationships between and among students and teachers, and foster learning, satisfaction, and a sense of a common humanity.

Empires on the Move:  Teaching and Researching Colonization and Mobility

Sponsor: Alliance to Advance Liberal Arts Colleges
Award Date: 07/19/2018

“Empire on the Move” will explore the intersections of academic work and pedagogy of a group of interdisciplinary scholars whose interests align with the themes of empire and mobility.  New works in history, literature, and anthropology, among other disciplines, demonstrate the significance of this topic, particularly because their visual, literary, and cartographic analyses lend themselves to digital learning initiatives.  By encouraging participants to think through teaching and research together the workshop will invite scholars to embrace this field as a way of enhancing cross-disciplinary endeavors and to return to their respective campuses with new ideas about the state of the field.

REU Site Proposal Building dictionaries to support endangered languages and preserve environmental knowledge in Mexico, Micronesia, and Navajo Nation

Co-PI's: Brook Lillehaugen, Ted Fernald, & Jamie Thomas
SPONSOR: NATIONAL SCIENCE FOUNDATION

AWARD DATE: 12/05/2014

The project builds bridges between indigenous linguists in the US academic community, Mexico, Micronesia, and the Navajo Nation, with collaborative research that benefits all parties. It helps uncover deep connections between languages and landscapes by documenting the knowledge base about the natural world found in endangered languages. The resulting linguistic materials support local communities' language revitalization efforts. They will also be a resource to the broader scientific community seeking to understand language complexity, diversity and universals. The project begins with a two-week intensive, hands-on training session on current best practice for recording languages (or areas of grammar within languages) that have not yet been adequately documented. Students learn directly from professional linguists and indigenous language experts how endangered languages are being modernized, digitized, and expanded into new technological domains. In weeks three and four, students participate in a two-week field practicum. Working in teams led by indigenous language experts, students help record basic and specialized lexica, folk taxonomies, toponyms, and ethno-biological nomenclature. They explore and help document the rich knowledge base in each language that uniquely encodes the natural environment (flora, fauna, weather, geography, etc.). They also learn current best practices in sustaining indigenous languages and supporting global language diversity.

RISE (Reading Involves Shared Experience) ebooks for deaf children

SPONSOR:  DOLFINGER-MCMAHON FOUNDATION
AWARD DATE:  06/13/2017

RISE ebooks are a product of collaboration between Gallaudet University and Swarthmore College since 2013. Students from both institutions collaborate with children from the Pennsylvania School for the Deaf to create new RISE books. Our ebooks help deaf children—a group that, by and large, has been left out of the joys of reading—step into the world of books. We hope to secure the future sustainability of this initiative by helping produce the next generation of sign storytellers for bilingual-bimodal books.

Missing Voices: Why Poor and Working-Class People Avoid Politics
Andrew Carnegie Fellowship

SPONSOR: CARNEGIE CORPORATION OF NEW YORK
AWARD DATE: 04/28/2021

This project seeks to understand a fundamental issue in American Democracy – the deep class and racial inequality in who participates. Missing Voices aims to address disparities in political participation by working with poor and working-class people to understand how they view electoral politics.The research builds on over 100 interviews already conducted, which demonstrate that poor and working class people often view politics as only for the rich. This project will use interviews and focus groups to discover how poor and working class people experience political organizations’ attempts to mobilize them, and why those attempts so often fail.
