India and China’s “Development Cooperation” with Africa: The Case of Pharmaceutical Companies
Both India and China have dramatically increased their engagement with Africa in recent years. Chorev’s project, one of the first comparative studies in this area, will examine the very different strategies employed by Chinese and Indian pharmaceutical companies when trading with African countries. Through interviews with drug companies in India and China, and distributors and regulators in Nigeria, Tanzania, and Kenya, Chorev will study the strategies employed by the Chinese and Indian companies, the causes for their chosen strategies, and the respective impact they have on the economic and social development in the African countries. Chorev’s research has the potential to make a number of important contributions to current scholarly and policy debates on African development, including insights into the types of commercial relations more likely to be beneficial for the receiving countries.

Stem cell enrichment via molecular beacon technologies
Adipose-derived stem cells pose exciting possibilities for cell-based regenerative therapies. However, stem cells must first be separated from other cell types before therapeutic use, a process that has proven difficult using standard approaches. Darling offers an alternative strategy using recent findings in his lab that shows molecular beacons can be used to visually identify stem cells that express genes associated with specific tissues, like bone. Since molecular beacons function by emitting narrow wavelengths of light, labeled cells can also then be rapidly sorted via flow cytometry. Furthermore, multiple flourophores can be employed to target several genes simultaneously, which would increase the specificity of the sorting process. Darling aims to develop and evaluate a set of molecular beacons that will facilitate the study of stem cell heterogeneity while also providing possibilities for clinical translation.

Uncovering biases in gene recruitment during the evolution of C4 and CAM photosynthesis in flowering plants
CAM and C4 photosynthetic syndromes have both played fundamental roles in the evolutionary success of flowering plants, but investigations have historically focused on each as separate and unrelated adaptations. Edwards’ novel approach is to study the similarities instead, in the hopes of better understanding the preconditions that would promote the evolution of one pathway over the other. This project will examine a plant lineage that has evolved both CAM and C4syndromes multiple times over the past 30 million years. Edwards will analyze the transcriptomes of select species and identify the major gene lineages that have been recruited into each origin of CAM and C4. Edwards expects to show that, regarding ancestral enzyme diversity, there was not a strong genetic constraint driving the evolution of one syndrome over the other.

The Geography and Policy of Depopulation in the Developed World: A Pilot Study on Germany and the United States
Research in geography, planning, and related fields typically focuses on issues related to population increase, but for much of the developed world growth in some locations is paired with population decline in others. Franklin’s project will develop two case studies as the basis for a larger research proposal on sources and impacts of population decline in the developed world. The United States represents localized population decline in the context of overall population increase. Germany, in contrast, is a highly developed country faced with the near-term prospect of population decline. Franklin aims to establish the geographical scale of population decline in both countries, to develop a typology of declining places, and to offer an assessment of the range of policy responses proposed in both countries to meet the current and future challenges of population decline.

Statistical Methods for Combining Multiple Biomarkers in Cancer Studies
With improved biological and medical technologies, non-invasive and accurate imaging biomarkers are more commonly used for disease diagnosis and screening. The integration of multiple biomarkers has emerged as an important method in cancer management for its potential to improve prognostic or predictive accuracy; however, few statistical methods currently exist to accommodate multiple biomarkers and assess their effectiveness. Kim proposes to develop a novel statistical method for combining multiple, continuous-scale imaging biomarkers to evaluate response to cancer treatment. Additionally, this project will develop user-friendly, open-source software that implements the method developed in this project. Kim’s research has potential clinical roles in individualized cancer therapy and the improved management of cancer patients.

Novel statistical techniques in astro-particle physics
Koushiappas aims to tackle one of the most interesting problems in astro-particle physics: the origin of diffuse light at very high energies (γ-rays), or light that does not seem to originate from any sources. An analogy can be made with viewing the distant lights of a city. One cannot distinguish every single light bulb in the city, but collectively one sees "diffuse" light originating from this direction. In astro-particle physics, this diffuse light corresponds to γ-rays, and the physical processes that give rise to γ-rays point to interesting and exotic sources such as active galactic nuclei, black holes, cosmic rays, and perhaps dark matter. Koushiappas will apply novel mathematical techniques to state of the art data from the Fermi Gamma-ray Space Telescope. Using this new statistical approach, coupled with experimental data, Koushiappas expects to shed light on the complex properties and origin of γ-rays.

A large-scale drug screen for healthspan-extending interventions
As life expectancy increases in industrialized countries, more people are at risk of chronic age-related diseases such as diabetes and heart disease. An effort is under way to identify pharmacological interventions that can reduce such risks, but large-scale experimental testing of drugs is still prohibitively time-consuming and expensive. To address these challenges, Neretti proposes to perform an in silico large-scale drug screen by using a novel algorithm to compare changes in gene expression across experiments; this algorithm has successfully identified a significant similarity across species between resveratrol treatment and dietary restriction, one of the most robust interventions known to extend lifespan in several model organisms. This methodology aims to identify new associations between existing drugs and healthspan, and will be the basis for additional studies in experimental gerontology.

Tracing Middle Babylonian Scholarship: Text, Transmission, and Tradition in Nippur, ca. 1500–1000 BCE
Archaeologists working in Mesopotamia (Iraq) have recovered thousands of clay tablets inscribed with cuneiform writing, many of which the work of ancient scholars who produced various written forms of knowledge, including medicine, divination, and lexicography. This book project will study ancient scholarship in the Babylonian city of Nippur in the late second millennium BCE, a transitional and formative period for cuneiform literature as a whole. Rutz will gather together manuscripts scattered in museum collections in the US, Germany, and Turkey, and study this corpus using a powerful imaging technique, Polynomial Texture Mapping, as well as a well-established platform for digital publication, the Open Richly Annotated Cuneiform Corpus. These digital images and text editions will be used to study the texts’ contents within the wider context of early Mesopotamian scholarship.

The Invention of the Intellectual: Edwardian Fictions of Decline
A growing chorus of writers have recently deplored the demise of the public intellectual in contemporary culture. If the figure of the intellectual is in decline today, when was its height? This project offers a pre-history of the current debate over the death of the intellectual, uncovering the nineteenth-century origins of our idea of the modern intellectual and our fear at its disappearance. Looking at British authors, poets, and social critics of the late nineteenth century and Edwardian period, Ryan’s project examines the crucial role these writers played in shaping public and literary discussions over cultural authority both then and now. Ryan will consider the debates specifically as a response to the increasing professionalization of science at the end of the nineteenth-century.

A visual artist, Tarentino makes monumental, panoramic watercolor drawings and digitally altered photographic prints that are about transforming the contemporary American vernacular landscape into a fantastic imaginary place. Picture windows are designed for an unobstructed view of the landscape as if through a picture frame. Adopting that framing convention, Tarentino presents in the place of a typical view of a suburban neighborhood, a dreamy, ambiguous view of an otherworldly landscape. Multiple, overlapping curtain‐like layers of sheer fabric will be printed with digital photographs that together form an imaginary landscape constructed like a collage. With a rich surface texture and the physical presence of a large relief sculpture, this project made with digital printing is more like a hybrid of drawing, painting, and sculpture than it is a traditional photographic print. Picture Window will be presented in a solo exhibition in South Korea, in June 2012.

Uncovering Racial Dynamics in American Politics with the 2012 Cooperative Congressional Election Study
Tesler’s research suggests that the election of President Obama ushered in a new contemporary highpoint for the influence of racial considerations in American politics.This project supports the purchase of data from the 2012 Cooperative Congressional Election Study (CCES) that will provide unparalleled insights necessary to support a comprehensive account of racial dynamics in American politics since the 2008 Election. Access to this data will allow Tesler to develop his research about race and the Obama presidency into a second book, and to advance his secondary research projects on political communications. Moreover, CCES data will become an important public resource for all students of American political behavior at Brown.

Forty More Years
Forty More Years will be an hour-long video about the 2012 Republican National Convention in Tampa, FL. Shot on vintage Portapak video cameras, it will adopt the documentary strategies and methods of Four More Years, a canonical videoshot on Portapaks by the guerilla video collective TVTV 1972 at the Republican National Convention in Miami, FL. In this way, Tribe aims to investigate the potential of obsolete video technology for contemporary practice. This project will compare and contrast the 2012 RNC to the 1972 RNC, focusing particularly on the spectacle of political performance and the ways in which it is represented in mainstream media (television) and critiqued in alternative media (guerilla video). Further, Tribe hopes to advance the field of contemporary media art by revisiting a historically important work, and, in so doing, reframing contemporary American party politics as a reenactment of its own history.

Before the Nation and Beyond Hybridity: Popular Music in Belle Epoque Brazil
Since the 1930s, research on the work of Brazilian popular musicians has been defined by issues of hybridity and national representativity. Earlier music is typically treated as a precursor to representative genres like samba and bossa nova. Tucker argues that a serious consideration of alternate visions of musical activity that informs Brazilian cultural life is overdue. In examining letters, performance programs, sheet music, and criticism from choro music from Brazil’s Old Republic (1889-1930), Tucker means to look beyond the issue of national sentiment, and ask how the era’s musicians and audiences conceived of music’s purpose; how the working out of these ideologies during a musical career led performers to connect different listenerships to different genres; and how these genres thereby came to bear a variety of distinct cultural values.

Tension regulated phase separation in biomimetic multicomponent membranes
Cells and cellular organelles are encapsulated by membranes composed of hundreds of lipids. This lipid diversity is essential for cell functions such as signaling: lipid mixtures organize into rafts, which serve as platforms for molecular-binding events at the membrane interface. Raft dynamics is regulated by physico-chemical variables like composition, temperature, and tension. Vlahovska’s proposed research centers at the effects of tension on raft evolution and stability, which is virtually unexplored due to difficulties in tension control and quantification. Vlahovska proposes the use of electric fields and microfluidic flows to create well-defined tension conditions that will allow her to experimentally investigate lipid demixing and domain evolution in tense membranes. This knowledge will benefit bioengineering applications that exploit cell signaling machinery, e.g., targeted drug delivery.

The Evolution of Sacred Space in the Abydos North Cemetery
Family seat and burial ground for kings of the First Dynasty, Abydos is one of the most important sites in Egypt. Its mortuary significance, lasting more than 3000 years, was ultimately predicated on the fact that the earliest kings were buried there. Despite the Egyptians’ dependence on a long historical perspective in developing the built and conceptual landscapes of Abydos, most excavations of the area have focused on a single time period. By contrast, Bestock’s project proposes a six-week excavation specifically designed to shed light on the complex process by which later users of Abydos incorporated elements of the past. Building on previous excavations in the Abydos North Cemetery, Bestock will examine remains from three distinct periods of its history.

Indian and African Slavery in Colonial New England
Although New England successfully reinvented itself as a bastion of liberty in the nineteenth century (vis-à-vis the slave-holding south), the reality in the colonial period was far more complex and interesting. Only recently have scholars begun to unpack the ways in which un-free labor and various forms of enslavement were central to New England social life and economy. Building on recent regional investigations of colonial slavery, this book-length project will bring together for the first time a more comprehensive interpretive narrative of both Indian and African slavery and servitude in New England during the period preceding the Revolutionary War.

Energy Efficiency Exploration in Sensory Network Protocols
Wireless sensor networks are a new class of small, battery-powered computers embedded in the environment and useful in many settings, including industrial, health, urban, and environmental monitoring, home and building automation, agriculture, and disaster warning. The most critical resource when designing and deploying these systems is energy, as it is generally infeasible to replace or recharge their batteries once they are deployed. While much research into energy measurement for these systems has depended on simulations, Fonseca’s previous project involved building Quanto, a system that allows energy measurement of a live network, and evaluating its usefulness on small-scale experiments. This project seeks to address limitations in Quanto’s initial design, and ultimately propose optimizations to new and existing protocols that improve the usefulness and energy efficiency of these networks.

Recalibrating Life: the social lives around prenatal genetic testing in the Arab Muslim World
Genetic screening technologies, which can test fetuses for genetic abnormalities, place prospective parents in the unprecedented role of making decisions about the value of unborn life. Hamdy’s project examines the moral dilemmas surrounding prenatal genetic testing in Egypt and Saudi Arabia, complicating the universalism of Western bioethics and the notion of a singular “Islamic” response to emergent biotechnologies. The goal of the project is not only to provide a rigorous set of questions and guidelines in collaboration with stakeholders, but also to expand the analytical and theoretical frameworks of social scientific approaches to health, biotechnologies, and Islam.

An Expectation-Based Model of Discourse Processing
Research into sentence-level processing has consistently shown that readers do not wait until they have all of the information needed to construct the perceived meaning of the sentence. Rather they use the information at their disposal to generate predictions about likely meanings. Relevant cues can include probabilistic information about the types of structures licensed by the grammar and their relative frequencies, semantic cues, and fine-grained statistical information. This study will test the proposal that an expectation-based processing model can be extended to explain how readers construct meanings of larger works, by using self-paced reading time and visual world paradigms to test predictions against those of a priming based model, which is blind to discourse structure.

Establishing sub-nuclear domains of coordinate gene regulation
Coordinate gene regulation is a fundamental biological process essential to all cells. Larschan’s lab studies X-chromosome dosage compensation, a regulatory mechanism that increases transcript levels of genes on the male X-chromosome to equal those on the combined female X-chromosomes, as part of a long-term goal to define how proteins identify their targets within the nucleus. It has been proposed that the Male Specific Lethal complex, central to dosage compensation in Drosophila, first identifies high affinity sites on the male X-chromosome and then spreads along its length, though there currently exists no temporal data to support this model. Larschan’s project will develop an innovative cell induction system to define the dynamics of this process and provide a new paradigm for the establishment of sub-nuclear domains of coordinate gene regulation across species that will be relevant to all biological processes and disease prevention.

On the development of a research program in thermoacoustics
Thermoacoustic devices exploit the temperature changes associated with acoustic waves to convert between mechanical and thermal energy. Due to the thermodynamically reversible nature of sound, the energy conversion is efficient. The potential for innovation is far-reaching, with applications in matters of global interest such as water desalination, waste energy harvesting, and spot cooling of electronic circuits. Mandre’s research program, predominantly for undergraduate researchers, proposes scaling down these devices to the centimeter scale and using them to develop new thermoelectric materials, which would open doors to a new field of mechanics in thermoacoustic materials.

Public Advice: Controlling Knowledge through American Bureaucracy
Greater transparency and public participation in government agencies are commonly prescribed antidotes to bureaucratic secrecy, bias, and expansion of power. Yet, secrecy represents only one side of the power that information confers: government decisions to reveal information represent the second side. Transparency policies, such as public advisory committees, complement secrecy as sources of bureaucratic power. Moffitt’s preliminary analysis suggests that transparency through public committees creates spokesmen for executive branch policy positions and shapes public discourse. By analyzing public committees in the FDA and the Department of Education, this project offers a novel view that runs counter to standard arguments about bureaucratic power and contributes to current debates on the development of transparency policies to encourage agency accountability and capability.

Reforming Social Protection through NGO Delivery: Impact on Corruption and Food Security
Around the world, grave concerns over food security persist despite the presence of large-scale programs to combat hunger. One such program is the Targeted Public Distribution System (TPDS), a costly and extensive food security program in India. The TPDS uses “Fair Price” shops to sell grains and other goods to poor households at below-market rates. Unfortunately, the design of the program gives the government-appointed shopkeepers a strong incentive to sell goods on the black market. The Government of Punjab has begun experimenting with reforms to TPDS aimed at side-stepping shopkeepers and distributing goods to households through an NGO. This project seeks to evaluate the results of these reforms, consulting closely with the government as we collect, digitize, and analyze a crucial second wave of survey data.

The Puzzle of Musical Property: Decolonization, Digital Technology, and Musical Ownership in the 21st Century
The rise of digital technology, along with the emergence of the indigenous peoples’ movement, has called into question legal and informal norms of musical ownership. In response to rampant Internet filesharing, legislators, entrepreneurs, and musicians have been trying to imagine new normative orders to govern the circulation of music. Meanwhile, developing countries and indigenous peoples have called for an international legal regime to prevent the misappropriation of their culture by outsiders. Perlman’s proposed written account of these debates will examine their history, explain technical details for the non-specialist reader, and locate normative upheavals within a broad socio-cultural context, and as such will be the first major ethnomusicological study of these world-historical changes

Neural substrates for target selection for actions
Purposive action requires the selection of a single movement goal toward a target. Studies have shown that structures involved in movement planning and execution often exhibit activity related to target selection. Thus, activity related to eye-movement target selection has been identified in oculomotor areas, whereas activity related to reach target selection has been identified in skeletomotor areas. This project will examine the extent to which eye-movement related brain structures are involved in reach target selection, and conversely which reach-related structures are involved in target selection for eye movements. Results will also have profound implications for ongoing efforts to develop neuroprosthetic devices for people with paralysis or debilitating neurological disorders as well as a humanoid robot equipped with coordinated eye-hand movements.

In vivo analysis of negative feedback on transcription of BMPs, dpp and gbb
In the development of multicellular organisms, it is essential that cell-cell communication via intracellular signal transduction be regulated on many levels. The BMP signaling system serves as an important regulator of many developmental pathways in both vertebrates and invertebrates. Prior investigations into the regulatory mechanisms underlying the establishment and maintenance of a BMP signaling activity gradient critical for patterning the limb led to the discovery of a negative feedback loop. This project seeks to acquire results from in vivo experiments to address the roles of transcriptional regulators and BMP signaling itself in the expression of BMP ligands dpp and gbb.

Smuggling and State-Making: The Politics of Illicit Trade in American History
Andreas’ research traces the too often overlooked role of illicit commerce — and the policing of such commerce — in America’s birth, consolidation, growth, and international engagements. The central question that motivates his book project is: How has illicit trade shaped America, and how has this varied across time and illicit trading activities? In answering this question, he examines America’s engagement with the world as a battle over illicit trade, from smuggling untaxed goods and “trading with the enemy” in defiance of British imperial policies in colonial times, to illicit slave trading and Civil War blockade running in the 19th century, to migrant smuggling and drug trafficking in the 20th century, to “cybersmuggling” in the 21st century.

Identification and Characterization of the Adhesive Proteins of Caulobacter Crescentus Holdfast
C. crescentus is a bacterium that permanently attaches itself to marine substrata (including hulls of ships) using an adhesive organelle known as the holdfast — the strongest naturally occurring glue. Insight into the chemical composition of this unique material allows us to understand the properties of aquatic glue at the molecular level and could also lead to the design and synthesis of high performance “biotic” bonding agents. The overall goal of this proposal is to identify and characterize the proteinaeous component of C. crescentusholdfast using liquid chromatography and tandem mass spectrometry.

Sedimentary Hydrocarbon Functionalization by First-Row Transition Metals
Reserves of sedimentary hydrocarbons used in transportation fuels have diminished, yet other deposits in the form of tar sands, heavy oils, and natural gas reservoirs remain an expansive resource that are primarily exploited as energy sources — contributing substantially to climate change. A small fraction of these resources are used in the production of recyclable commodity chemicals for manufacturing consumer goods, such as plastics and lubricants; however, the chemical transformation of unreactive alkanes (the main component of sedimentary hydrocarbons) into precursors for commodity chemical production is inefficient. Bernskoetter proposes to develop cobalt and nickel metal sources as economically and chemically viable catalysts for such processes, thus enabling widespread utilization of sedimentary hydrocarbons in recyclable applications and perhaps ultimately fostering society’s responsible stewardship of these valuable resources.

Local News, Global Jews: An Ethnography of European Jewish Journalism
How do today's European minorities imagine the public sphere? How it is imagined for them? What political, economic and social implications do these imaginaries have? “Local News, Global Jews” enters into a timely conversation about Europeans' changing understanding of the public sphere by observing minority media makers, the texts, and the images they produce. We are increasingly subject to popular debates about the “death” and “rebirth” of journalism and, in many locales, a parallel rhetoric applied to Jewish culture itself. This project, the first ethnographic study of Jewish journalism, takes the example of European Jewish news to outline a theory of how minority journalists reckon with the global and local as well as the aesthetic and political pressures that define the publics they produce.

Custom-built Mechanical Testing Device for Determining Material Properties of Soft Biomaterials
Recent developments and advancements in regenerative medicine and tissue engineering have underscored the need for quantitative approaches and experiments in cell biology. In particular, it is necessary to understand the mechanical properties alongside the biochemistry of artificial tissues to guarantee long-term success after surgical implantation. Traditional mechanical testing devices are generally unable to provide accurate material information for soft biomaterials and tissues, and so Franck proposes to build a mechanical testing device specifically designed to characterize tissue and soft biomaterials for applications to study cell-tissue interactions quantitatively. The results from the mechanical testing device will be used in the development and prediction of cell motility and cell adhesion studies, which results are anticipated to advance our understanding in the emerging fields of tissue engineering and regenerative medicine.

Coming of Age in the Movement
Few histories of the civil rights movement focus on the children involved. Many of these children, now parents and grandparents, suffered some kind of trauma as a direct result of their activism or the activities around them. This project probes more deeply in the history of children and activism and the direct correlation to and significance of trauma. Hamlin draws on theoretical work from fields such as child psychology, children’s mental health statistics and care, trauma studies, and black communities and mental health. This project demands a rethinking of the civil rights movement history away from the triumphant-oriented narrative toward a more nuanced assessment of the prices paid by those who fought during the black freedom struggle.

Interpersonal Trust and Self-Regulation
According to most psychological theories, the decision to trust is a positive, if fragile, achievement. In contrast, traditional economists view the decision not to trust as the rational response. Krueger will run three experiments to test, and possibly refute, the following hypothesis: “Before a person decides whether or not to trust another individual, the options of trusting and not trusting are in a state of balance (i.e., they are equally likely to be endorsed a priori).” Guided by theory and research on self-regulation, he expects to find that distrust is a psychological default option, whereas the decision to trust requires mental work.

Standing Wave is planned as a large-scale, interactive, and kinetic sound installation that forms deeply layered and visceral patterns of sound and physical motion. A number of speakers and resonating objects are held aloft by a set of tall, flexible, motorized poles that move in large arcs. The motion of these objects resemble both the waving of flags and the launching of catapults; the fluctuation of meaning that this implies is central to the reading of the piece. The title, Standing Wave, describes the reflection and interference patterns created by sound waves as they dissipate their energy in an enclosed space — patterns that define the space acoustically as the patterns themselves are contoured by that same space.

High-throughput, Polychromatic, Compact Interferometric Sensor Array for Label-free Detection of Chemical and Biological Analytes
Detection of extremely diluted chemical and biological species is generally accomplished by using low throughput, non-scalable methods that rely on labeling the target analyte to reveal the presence of specific molecules within a single device. Pacifici proposes a new type of nanofabricated bio-chemical sensor, consisting of a dense, planar array of submicron-size interferometers milled in a thin metal film, each working as an individually addressable device, integrated on a single lab-on-a-chip. This approach relaxes the labeling requirements of conventional devices, allowing for unprecedented high throughput, universal sensing capabilities in an ultra-compact geometry.

Atom Probe Tomography of Geologic Materials
Atom-probe tomography (APT) is a rapidly advancing analytical technique holding great promise for geological sciences due to its unique combination of extremely high spatial resolution along with high sensitivity. A recent technology breakthrough has allowed pulsed-lasers to assist the analyses, so that now semi-conducting samples may be analyzed. The bulk of planets, as well as the moon, are made of Fe-bearing minerals that are semi-conductors. Thus laser-assisted APT has potential applications in nearly all geoscience fields, although to our knowledge, it has yet to be applied in geoscience. Parman’s proposed research explores the potential for APT analysis of both natural and synthetic geomaterials, focusing specifically on the mineral olivine, which is a main constituent mineral of many planetary interiors.

“Rouba, mas faz?”: Understanding Popular Attitudes Towards Corruption in Latin America
Indices published by the World Bank and Transparency International repeatedly rank Latin America’s democracies as among the most corrupt places in the world to do business. Cultural explanations are often used to explain the prevalence of corruption in the developing world, and the existence in the region of phrases such as rouba, mas faz — “he robs, but he gets things done” — seem to support this. However, cultural explanations overlook the possibility that voters choose to overlook political corruption only if they believe that politicians are otherwise competent at their jobs. This project will investigate popular attitudes towards corruption in Latin America, paying particular attention to citizen perceptions of the potential trade-offs between politician corruption and competence.

Genetic Dissection of Midbrain Dopamine Neuron Diversity
Heterogeneity of neuronal cell types is essential for the diverse functions of the mammalian nervous system including movement and cognition. Parkinson’s disease and schizophrenia are devastating neurological diseases and significant human health issues that involve midbrain dopamine neurons. These disorders arise from different etiologies and affect distinct subtypes of dopamine neurons. A currently problem is that we do not understand how dopamine neuron dichotomy is established during development. This project will identify novel genes that control the molecular identity of distinct classes of dopamine neuron progenitors. Determining the genetic logic that controls progenitor diversity will be instructive for understanding neural development. Additionally, uncovering how dopamine neuron progenitors are allocated will likely provide a molecular scaffold that can be exploited to effectively guide stem cells to acquire a unique dopamine identity.

Maternal Incarceration and Children’s Outcomes
Until now, analysis of the effect of maternal incarceration on children has been limited to existing studies that are narrow in scope, size and reach. Empirical literature offers little insight into the effects of the schooling environment, receipt of social welfare services, and the intervention of child protective services on their well-being. Employing a range of social science disciplines, from economics to psychology and sociology, Cho will examine a large, longitudinal population-based sample to provide information on both the short-term and long-term effects of maternal incarceration.
Kfir Eliaz, Associate Professor, Economics: $15,000
Decision making Under Ambiguity: Unknown probabilities vs. Unknown Outcomes
Almost all major decisions are reached with incomplete information. However, the research that grounds decision theory has relied solely on uncertain probabilities about certain outcomes. Eliaz will first aim to provide experimental evidence that individuals’ attitude towards ambiguity is sensitive to the domain of ambiguity. Moreover, an individual may be ambiguity averse when only probabilities are unknown but ambiguity loving when only outcomes are unknown. Then Eliaz will propose alternative models that accommodate these possible reversals in individuals’ attitude towards ambiguity. His findings will reach beyond economics into other fields that study decision-making and uncertainty, including psychology, cognitive language sciences, and neuroscience.

The Ruins of Babel: Linguistic Difference, Social Movements, and Violence
Dr. Faudree identifies a “systematic linguistic blind spot” — inattention to the practical consequences of language diversity — in both popular and scholarly writing on ethnic violence and cross-cultural social movements. As a remedy, Faudree will combine archival, oral historical, and ethnographic research to illuminate how language difference has been a factor in political violence and popular protest in Oaxaca from the Mexican Revolution of 1910 to the national teachers’ strike of 2006. The research will offer a fresh perspective on the practical politics by which social movements coalesce and social conflicts unfold.

Southern Beysehir Lake Basin Archaeological Research Project: First Field Season
Despite the growing scholarship on “places” and their meanings, little has been done to explore them on the ground. Harmanşah will investigate what ‘took place’ at the sites of carved rock reliefs and spring sanctuaries in Central Turkey that date from the Late Bronze and Early Iron Ages (ca. 1500-830 BC). Juxtaposing survey strategies of settlement archaeology, geomorphological analysis of changing landscapes, and the ethnographic and ethnohistorical research on the more recent past, he will explore everyday human activities that create fragile but culturally meaningful localities.

Nativity Differences in Health Trajectories During Adolescence and the Transition to Adulthood: Patterns, Determinants and Consequences in the United States
Roughly 20% of U.S. youth are first- or second-generation, meaning they were born abroad or have at least one foreign-born parent. How this group fares will reflect in patterns of social inequality and health, as well as in the composition and performance of the educational and health care systems. Current research suffers from two important limitations: a focus on infancy and a reliance on cross-sectional data that cannot identify long-term patterns and changes in those patterns over time. Jackson will analyze longitudinal data to identify nativity differences in adolescent health trajectories, as well as their socioeconomic determinants and consequences.

While many social scientists study the issues of labor migration, refugees and trafficking in terms of nation states, this project will focus through the unique lens of kinship. Leinaweaver will compare the lives of two populations of Peruvians in Spain: labor migrants and adopted children. Spain is a top foreign recipient of both Peruvian children in adoption and Peruvian migrant labor. The research will explore how the presence of one such “migrant” affects the integration and existence of another. Her work will lay a qualitative foundation for the concept of international adoption as a kind of migration.
Jason K. Sello, Assistant Professor, Chemistry: $15,000
Development of New Chemical Methods for the Analysis of Metabolites in Biological Samples
The goal of this project is to develop new chemical technologies that will facilitate characterization of metabolites. Given the universality of most low-molecular weight metabolites across all kingdoms of life, it is anticipated that the project’s methods will have a broad impact on research in the life sciences and in diagnostic medicine. Prof. Sello will use these technologies to engineer Streptomyces bacteria for the production of useful antibiotics. These bacteria are best known as producers of half of the 10,000 antibiotics discovered in the past sixty years; they produce two-thirds of the antibiotics used in clinical medicine as antimicrobial drugs, anticancer agents, and immunosuppressants. The proposed work will place Brown University at the forefront of metabolic engineering and analysis, burgeoning areas of biotechnology and medicine.

Tropical Climate Forcing and Biotic Provinciality in Triassic-Jurassic Pangea
Based on an analysis of the distribution of terrestrial biotic communities on the supercontinent of Pangea, which lacked significant geographic barriers, biotic provinciality develops due to climatic zonation, including patterns of variability, and ecological barriers. This project aims to collect and analyze core samples from the Triassic (220 Ma) Deep River basin, the Dan River Basin and the Newark Basin in order to examine the correlation between climate proxies and biotic provinces of tetrapods within narrow swaths of time constrained by existing paleomagnetic stratigraphy and cyclostratigraphy. Data and conclusions from this project will form the basis for several research proposals to extramural programs, and will contribute to the development of a tropical continental paleoclimate research program in the Department of Geological Sciences at Brown.
Vazira Fazila-Yacoobali Zamindar, Assistant Professor, History: $15,000
Ruined Histories: Archaeology, Islam and the Making of Gandhara Art in Divided South Asia
This project engages contemporary questions around Islam's relationship to non-Islamic material culture by investigating the colonial and postcolonial history of a World Heritage Gandharan Buddhist site, Takht-e-Bahi, in a Muslim region on the northwestern frontier of Pakistan. It examines transformations in the meaning of the ruins through the discursive and institutional interventions of archaeology ‘on the ground’, and how they shaped relationships of Muslims to the site. The Salomon Grant will enable Zamindar to draw upon her well-established personal and research networks in Pakistan to conduct potentially path-breaking research where few, if any, American scholars are able to go at present.
Rashid Zia, Assistant Professor, Engineering: $15,000
Direct Laser-Writing of Epitaxial Graphene
This Salomon project explores a new fabrication technique which leverages the electromagnetic resonances to synthesize graphene – an electronic material of tremendous potential. In collaboration with the Molecular Beam Epitaxy Laboratory of Professor Rod Beresford, this project investigates a selective laser irradiation technique to grow patterned, large area graphene devices on insulating CMOS compatible substrates.
Inscriptions are to students of ancient society what documents are to historians of more modern periods: essential primary sources. Their publication in print, however, has always been problematic and is becoming increasingly impractical. Brown has rich but scattered resources in the emerging area of digital epigraphy; a central administrative umbrella for projects in this area will facilitate cross-fertilization and will enable more efficient use of existing resources. It will also establish Brown as a leader in the field nationally and, in certain respects, internationally. For the first year, the Center will support two existing projects, “The U.S. Epigraphy Project” and “Inscriptions of Israel/Palestine.”
Nitsan Chorev, Assistant Professor, Sociology: $15,000
From Smallpox to HIV/AIDS: On the Global Governance of Health
Health policies advocated by international organizations have rarely been based on biomedical knowledge alone. Rather, international health policies, like other international initiatives, reflect political considerations and economic calculations. Chorev’s proposed book project will offer the first comprehensive analysis of the political-economic dynamics underlying international health cooperation, from the establishment of the U.N. World Health Organization in the 1940s to the present. Drawing on an extensive original research, Chorev will examine how North-South relations, struggles among international organizations, and the rise of multinational corporations, private foundations and non-governmental organizations, affected the shifts in international health policies.
Deborah Cohen, Associate Professor, History: $15,000
Family Secrets: The Rise of Confessional Culture in Britain, 1840-1990
Cohen examines the interplay between families and secrecy over the course of a century in a half in Britain. Charting the shifting boundaries between what was considered private or shameful, and what could be freely disclosed, she makes two main arguments. First, there is no straightforward story of progressive, enlightened de-closeting to be told; different family secrets had different trajectories. Second, families did not simply enforce social norms. Rather, they played a crucial role in arbitrating and even creating them. Cohen’s grant will fund archival research in Britain. Her book, “Family Secrets,” is under contract to Viking Penguin.
Sarah Delaney, Assistant Professor, Chemistry: $15,000
Elucidating the Roles of DNA Damage and Repair in Trinucleotide Repeat Expansion
The molecular basis for a family of neurological disorders, including Huntington’s disease and fragile X syndrome, is the expansion of a trinucleotide repeat region of DNA. These repetitive regions are known to form non-canonical secondary structures and, furthermore, recent work in mice has implicated DNA damage and repair in the expansion. Delaney plans to study the mechanism by which the disease-initiating expansion occurs by unraveling the connections between secondary structure, DNA damage, and repair. A molecular level understanding of how the expansion occurs will enable the design of agents to inhibit this process and consequently prevent a variety of neurological disorders.
Gerwald Jogl, Assistant Professor, Molecular Biology, Cell Biology and Biochemistry: $15,000
Structural Biology of the Human Sir2 homolog, Sirt6, in complex with the Gcip tumor suppressor
Mammalian homologues of the yeast Sir2 histone deacetylase target a multitude of cellular proteins in addition to histones. These enzymes function as protein deacetylases or ADP-ribosyltransferases and have been implicated in processes such as chromatin regulation, DNA maintenance, and energy metabolism. They are considered promising targets for drug development against cancer and aging-related diseases. Human Sirt6 is a chromatin-associated protein, which is essential in DNA base-excision repair. Jogl’s research will attempt to determine the three-dimensional structure of Gcip (Grap2 and Cyclin D Interacting Protein) alone and in complex with Sirt6 to study the structure and function of their interaction.
Stratis Papaioannou, Assistant Professor, Classics: $14,600
Study, Edition, and Translation of the Writings of Michael Psellos (11th cent., Byzantium)
Prolific writer, ingenious courtier, and radical thinker, Michael Psellos (1018 - ca. 1078, Constantinople) represents Byzantine culture at a transitional moment. The eleventh-century is a time when across Europe a movement from premodern to modern cultural patterns is palpable, and Psellos, writing in Medieval Greek, is the earliest and most eloquent figure of this transition. Papaioannou has a comprehensive approach to his research on Psellos: he is completing a study of Psellos' aesthetics and autobiography, editing Psellos' letter-collection for the Teubner Series, and, in collaboration with an international team of scholars, he is preparing an anthology of Psellos' texts in English translation.
Sherief Reda, Assistant Professor, Engineering: $15,000
ProHunter: A Platform to Accelerate Protein Identification from Mass-Spectrometry Data
Mass-spectrometry based proteomics is a powerful technology for protein identification. One of the main challenges in this technology is the sheer volume of data that needs to be processed and analyzed. Despite the algorithmic advances in the last few years, mass spectrometry data analysis remains computationally challenging. Reda’s project will be the design and implementation of a new reconfigurable software/hardware platform that accelerates protein identification from mass spectrometry data using commodity hardware components. In addition to increased speed of computation (more than 1000x), the proposed platform will allow researchers to substitute bulky computer cluster nodes with a small inexpensive device running the same computations much faster and at a much reduced cost.
Deborah Rivas-Drake, Assistant Professor, Education: $15,000
An Examination of Changes in Ethnic Identity and Campus Engagement Among Latino College Students Over One Year
Rivas-Drake’s research will examine the identity processes and academic and social adaptations of Latino students in higher education settings. One of her goals is to identify specific ways in which academic and social contexts inform Latino students' ethnic identity beliefs. She also seeks to identify the ways in which ethnic identity beliefs influence students’ decisions regarding how to spend their time in terms of academic work, extracurricular involvement, and recreational activities. Understanding changes in Latino students’ decision-making processes longitudinally will provide critical insight for programmatic efforts aimed at retaining such students in higher education.
Joseph "Butch" Rovan, Associate Professor, Music: $13,700
Studies in Movement
Studies in Movement pays homage to the great French physiologist and inventor Etienne-Jules Marey (1830-1904). Marey analyzed, by means of non-invasive sensor systems and stop-action photography, the motion of humans and animals in the natural world. Rovan’s multimedia project, which includes musical composition along with the development of custom gestural interfaces of his own design, will reconsider Marey’s legacy by combining his words and images with new sounds and gestures. The material for the performance aspect of the project—text, music, and image—will draw on Marey’s considerable vision: technical writings, photographs, engravings, and the mysterious graphic tracings from a wide array of his uncommon writing machines.
Vivek Shenoy, Associate Professor, Engineering: $15,000
Mechanics of intracellular pathogens and biomimetic systems propelled by actin comet tails
A number of pathogenic bacteria responsible for diseases like listeriosis, meningitis and gastroenteritis hijack the protein machinery of the infected cells to form a filamentous actin comet tail that propels them within these cells and to other cells in their neighborhood. A physical understanding of the forces that lead to this motion can provide a means to control spreading of infections to healthy cells. Shenoy’s preliminary research has derived a dynamic model that provides a unified description of the seemingly unrelated trajectories of bacteria. The goal of his proposed work is to understand how macroscopic variables in the trajectories are related to molecular level properties of the actin filament network such as the statistical distributions of their lengths and orientations, degree of cross-linking and kinetics of polymerization.
Marcus Spradlin, Assistant Professor, Physics: $15,000
New Computational Methods in High Energy Physics
Spradlin's research has focused on the development of efficient new algorithms for performing otherwise formidable calculations in gauge theories such as quantum chromodynamics, which describes the strong nuclear force. This project aims to put these theoretical advances to practical use by involving Brown undergraduates in building efficient and user-friendly computer software tools. This project will lead to technology that would be of great benefit to the field, rendering feasible a number of important calculations in theoretical physics which are presently out of reach.
Tracy Steffes, Assistant Professor, Education: $15,000
A New Education for a Modern Age: School, Society, and State, 1890-1940
Steffes’ project explores the efforts of reformers to define a “new education” for modern, industrial society in the early twentieth century. She will analyze the ways in which the organizational changes in schooling extended the reach and power of the school and the state over young people in new ways. In taking a national approach and placing it within the broader context of American responses to modernity and American political development, this project offers a significant reinterpretation of educational development in this period which places the growing role of state authority and national policymaking at the center.
Daniel M. Weinreich, Assistant Professor, Ecology & Evolutionary Biology: $16,000
The Genetic Basis of Adaptation to Novel Environments in Laboratory Microbial Populations
Since Charles Darwin’s observation that natural selection occurs whenever individuals that reproduce more successfully transmit at least some reproductive advantage to their offspring, theory has far outstripped data. Biological novelties often arise when an organism’s environment changes, but the genetic details of this process remain largely unknown. Weinreich’s proposal uses the bacterium Escherichia coli to test the importance of preexisting genetic variation when adapting to new environments. The theoretically most intriguing possibility is that mutants with lower than average fitness in their own environment have higher than average fitness in a new environment.
Ana Baylin, Assistant Professor, Community Health: $15,000
Genetic Modification of Triggers of Acute Myocardial Infarction
Baylin's overall objective is to identify genetic modifiers of triggers of acute myocardial infarction by examining genes involved in the beta-adrenergic pathway and the caffeine metabolism pathway. Using a novel case-crossover design, it has been established that heavy physical exertion and coffee are potential triggers of acute myocardial infarction. This study offers an unusual opportunity to expand our understanding of how genetic background can modify the triggering effect of transient risk exposures and will help us in identifying subgroups of individuals who may be more responsive to the adverse health effects of some triggers than others.
Richard J. Bennett, Assistant Professor, Molecular Microbiology and Immunology: $15,000
Genetic Epigenetic Variation in the Human pathogen Candida albicans
C. albicans is normally a commensal organism, living as a benign part of the microflora in the gastrointestinal tract. However, it is also an opportunistic pathogen and is capable of causing life-threatening systemic disease due to its ability to exist in many host environments. C. albicans has evolved adaptive mechanisms to populate and thrive in diverse niches, and Bennett's research focuses on the adaptations that have made it efficient at colonization and infection in the host. Bennett will focus on an epigenetic process that allows C. albicans to undergo a rapid and metastable switch in phenotype.
Wayne D. Bowen, Professor, Molecular Pharmacology, Physiological, and Biotechnology: $15,000
Correlation of Sigma-1 Receptor Expression and Function with Indicators of Tumor Aggressiveness and Metastatic Potential
This study focuses on the major contributor to cancer deaths: tumor metastasis. Recognizing that rapidly dividing tumor cells and cells that are highly motile have a greater chance for metastasis, Bowen will study Sigma-1 receptors. These receptors serve as ligand-regulated amplifiers of calcium signaling by enhancing the inositol triphosphate-induced release of calcium from the endoplasmic reticulum when agonist activation of G-protein coupled receptors stimulates phosphoinosite turnover. This study will utilize related breast tumor cell lines, MCF-7 and MDA-MB-231, which are weakly and strongly metastatic, respectively, and Bowen's sigma-1 overexpressing cells, Line 41. Bowen and his team will attempt to correlate the expression level of sigma-1 receptors to proliferative rate, sensitivity to mitogens, and changes in cell motility. The study could lead to use of sigma-1 receptor expression as a marker for metastatic potential and as a target for drugs that block proliferation by blocking the receptor.
Elizabeth J. Bryan, Associate Professor, English: $5,670
Vernacular Text Production in Medieval England and Spain
This project focuses on the emergence of early Middle English texts in the late 12th and early 13th centuries. Bryan will investigate the possibility that the political relationships between Plantagenet monarchs of England and the royal houses of Castile in the twelfth and thirteenth centuries created a climate in which the "idea" of producing texts in vernacular languages, rather than in Latin, might have been mutually influential.
Caroline Castiglione, Assistant Professor, Italian Studies: $7,935
Extravagant Pretensions: Women and Family Conflict in the Public Sphere of Rome, 1650-1750
In early modern Rome, aristocratic family conflicts were negotiated by very public means: petitions, letters, trials, and new spheres of sociability, the "conversazioni." To the regret of some male contemporaries, women frequently reshaped popular opinion in their favor, and won the support of popes and papal magistrates. In Castiglione's project female and male viewpoints will be comparatively analyzed to further our understanding of how aristocratic Roman families survived and were influenced by such controversies. The study will also illuminate the origins of the greater freedoms women came to enjoy in the eighteenth century, the respective roles that women and men played, and the larger impact of such changes on the culture of early modern Rome.
John Cherry, Professor, Classics and the Joukowsky Institute for Archaeology and the Ancient World: $15,000
The Vorotan Project, Southern Armenia: 2007 Season
Cherry's archaeological research explores the long-term human utilization of the Vorotan River corridor (Syunik marz, Republic of Armenia). The team's interests, encouraged by successful fieldwork in 2005 and 2006, revolve around the diachronic record of settlement and exploitation of this river course, and the strategic history of what has long been a recognized passageway for movement, contact, and exchange within the southern Caucasus. In 2007 Cherry will focus on four specific goals for fieldwork: 1) Regional connectivity and control, 2) Test excavations, ceramic study and architectural mapping, 3) Mortuary landscape analysis, and 4) Obsidian studies.
Jennifer Dworak, Assistant Professor, Engineering: $15,000
An Investigation of Pattern-Limited Test Sets for the Detection of Errors Caused by Random Defects, Systematic Defects, and Process Variations
Achieving adequate reliability of integrated circuits (ICs) is a critical problem facing today's semiconductor industry, especially as fabrication processes shrink below 90 nanometers to 65 and 45 nanometers and beyond. As feature sizes decrease systematic defects and process variations become increasingly significant. Dworak's research will explore the detection of systematic and random defects with test sets of limited size. This research will determine the degree to which defects can be detected on groups of ICs with varying defect and process variation characteristics as a function of test set length and quality.
Thalia Field, Assistant Professor, Literary Arts: $15,000
Using primary source materials, Field is researching a book entitled, Experimental Animals. Her work inhabits a territory where cultural/science history and innovative fiction overlap. Her passionate stories intertwine through various narrative “experiments,” emerging into a portrait of science and aesthetics as they become increasingly specialized and bound together in the modernist imagination. This project brings together the historical root of the aesthetic term “experimental” and the cultural, scientific and ethical implications of vivisection as it mobilized the artists and scientists of the 19th century.
Matthew Garcia, Associate Professor, American Civilization: $15,000
The Rise and Fall of the Farmworkers Movement: Race, Labor and Justice on the California-Mexican Border, 1940-1980
Garcia's study will explore the Farmworkers Movement from its formation to the purges and defections of key organizers and members of the United Farmworkers Union (UFW). This work focuses on the grassroots efforts of ordinary people, men and women, in the making of a social movement. This project seriously examines the successes and shortcomings of the movement so that we may understand the degraded status of workers who feed the nation and the world today.
Mark Johnson, Assistant Professor, Molecular Biology, Cell biology and Biochemistry: $15,000
How do gametes fuse? Identification of Egg-expressed Proteins Required for Sperm-Egg Fusion
Fertilization is of central importance to the life cycle of all sexual organisms, yet we know very little about the molecules responsible for the fusion of gametes. Using a genetic screen, Johnson has analyzed fertilization mechanisms in the flowering plant, Arabisppsis thaliana and identified a mutation, HAP2, a sperm-expressed gene essential for fertilization. The HAP2 gene encodes a membrane localized and sperm-specific protein. Johnson hypothesizes that HAP2 protein on the surface of the sperm interacts directly with proteins on the surface of the egg and that these protein:protein interactions mediate sperm:egg fusion. Johnson proposes to identify proteins that interact with HAP2 and are required for fertilization.
David Lindstrom, Associate Professor, Sociology and PSTC: $15,000
Migration and Marriage: Union Formation and Dissolution among Mexican Women in Mexico and the U.S.
Using data which provides a unique bi-national, nationally representative pooled sample, Lindstrom examines the impact of U.S. migration on union formation and dissolution among Mexican origin women. The primary objectives of this study are: 1) describe the marital experiences of Mexican origin women in the United States and Mexico, 2) compare marital patterns for first and second generation Mexican immigrant women to non-migrant women in Mexico and native non-Hispanic white women in the United States, 3) identify the relative impact of migrant selectivity, time spent in the United States, and immigrant generation on the likelihood of entry into a union, type of union (marriage verses cohabitation), and union stability.
G. Tayhas R. Palmore, Associate Professor, Engineering: $15,000
Improving the Stability of Polymer-Based Batteries
This proposal seeks to evaluate the stability of polymer-bases batteries for energy storage recently developed in Palmore's laboratory. Palmore's team will fabricate battery prototypes and subject said prototypes to a fixed load for repeated cycles of recharging and discharging. The prototypes will be dismantled and their polymer composites evaluated for mechanisms of degradation (oxidation, leaching of components, dendritic growth) using a variety of spectroscopic and imaging tools (NMR, FTIR, UV-Vis, SEM, AFM, STM, and XPS). Once primary mechanisms of degradation are identified, Palmore will modify the polymer composites to circumvent these deficiencies.
James M. Russell, Assistant Professor, Geological Sciences: $14,850
Paleoclimate Changes and Tropical Glacier Dynamics in the Rwenzori Mountains, Uganda-Congo
Understanding the causes, magnitudes, and frequency of decade-to-century-scale climate variability is crucial to future climate prediction and the development of sound water resource management strategies in sub-Saharan African, yet out knowledge of these events remains rudimentary due to a lack of long, quantitative, high-resolution paleoclimate records. Russell will conduct fieldwork to recover sediment cores from six lakes in the Rwenzori Mountains, and will make laboratory investigations of the age, composition, and stratigraphy of those cores to understand climate variability and glacial history in this unique alpine ecosystem.
Hilary Silver, Associate Professor, Sociology and Urban Studies: $15,000
Explaining Neighborhood Change: The Case for South Providence
Silver's research examines whether Providence's redevelopment or local efforts mainly account for improvements and demographic changes visibly occurring on the South Side of Providence, and whether the improvements represent incumbent upgrading or gentrification. What is the impact of downtown redevelopment on low-income, minority neighborhoods? The answer is of practical as well as scholarly significance. Learning who benefits from urban economic growth obviously has implications for policy, but is also at the center of theories in the fields of urban planning, sociology, economics, and politics. Each discipline helps explain why neighborhood renewal varies across places.
Richard Snyder, Associate Professor, Political Science: $15,000
Does Lootable Wealth Breed Chaos? Natural Resources and Political Order in Comparative Perspective
With the main empirical focus of the project being the three Andean countries that are major producers of illicit drugs (Bolivia, Colombia, and Peru), Snyder will develop and test a novel theory of the contrasting political consequences of lootable wealth. Defining lootable wealth as high-value goods with low economic barriers to entry, Snyder argues that different types of institutions of extraction can be constructed on such goods -- with contrasting consequences for political stability. Within this political economy framework, Snyder will advance a more powerful theory of collapsed states and civil war, one that accounts both for disorder and order in the face of lootable wealth.
Suzanne Stewart-Steinberg, Assistant Professor, Italian Studies and Comparative Literature: $15,000
A History of Italian Repression
Stewart-Steinberg's analysis of Italian culture that begins with 1900 and ends in the present day is centered on a kind of knot tied around the problem of repression, a term that she understands in two senses: as a political term, one that must ask the question of the factuality and the legacy of Italian fascism, but also as a term understood in its psychoanalytic sense, that is, as the creation of both an individual and a cultural unconscious. Stewart-Steinberg will argue that these two meanings of the term are inextricably linked. While, the relative lack of impact of psychoanalysis in Italy has been amply noted, the connection between this lack and the history of Italian fascism has not. In this study, Stewart-Steinberg proposes to investigate precisely this connection, which, she believes, is crucial to furthering our understanding of not only Italian fascism itself, but also of those cultural forces that produced it and then, in its aftermath, dominated the cultural landscape of Italy until the present day.
Mark S. Bauer, M.D., Professor, Department of Psychiatry and Human Behavior
“Mad” Poets: Description, Deconstruction, and Destigmatization
This project focuses on the relationship of major mental illness to the creative process, in particular poetry. Unfortunately, much of the current discussion devolves to the level of “Was the poet ‘mad’ when s/he wrote this?” and “Does ‘madness’ help or hinders the poetic process?” Bauer’s work both as a published poet and as an internationally recognized expert in psychiatric diagnosis will provide a unique opportunity to bring both literary critical and clinical research experience to bear on these issues.
Janet Blume, Associate Professor, Engineering; Edward K.S. Chien, Assistant Professor, Obstetrics and Gynecology; Pradeep R. Guduru, Assistant Professor, Engineering
Measurement of Stress-Strain Response of the Cervix
This project will research the biomechanical properties of the cervix. Failure of normal cervical function leads to pregnancy loss and prematurity when it occurs early in gestation or results in prolonged pregnancy and cesarean section when it occurs late in pregnancy. This proposal brings together engineering and obstetrics to develop a device that will be used to measure the biomechanics of the cervix. The device will be used to investigate mechanisms responsible for cervical regulation and will provide quantifiable measures that can be mathematically modeled. In addition, this project will provide interdisciplinary research experience for Brown students, who will play an important role in the experiment analysis.

Cultural awareness in military operations: The production of knowledge through doctrine, training, education and simulation
Drawing primarily on qualitative social scientific methods, this project will document and analyze the growing attention paid to culture by U.S. and UN military institutions since the fall of the Berlin Wall in 1989. It focuses on how the challenges of missions such as Somalia, Haiti, Bosnia, Kosovo, Afghanistan, and Iraq have driven attempts by military planners and field commanders to define, acquire, disseminate and deploy knowledge about culture. It also explores the ethical and epistemological questions that these military operations raise for professional cultural analysts in the academy, whose input national and international organizations are now seeking.
Will Fairbrother, Assistant Professor, Molecular, Cellular Biology Biochemistry
Discovering Combinatorial Codes in Splicing
This project focuses on modules that are a combination of sequence elements in DNA or RNA that recruits multiple trans-acting factors which function in a coordinated fashion. Several computational methods have been developed to explore these higher order relationships in the field of transcription. Professor Fairbrother will apply these approaches to address an analogous problem in the field of splicing. The experiments are intended to discover how particular combinations of splicing elements are used to regulate alternative splicing.
Dmitri Feldman, Assistant Professor, Department of Physics
Spin Transport in Quantum Wires
This project focuses on the theoretical investigation of quantum transport in nanostructures. Professor Feldman proposes a new method of spin current generation and manipulation in quantum wires, called “the spin ratchet effect”. This effect plays the same role for spintronics as rectification plays in electronics. Insight from this research will be used to understand spin transport in realistic quantum wires, potentially leading to the development of new principles of nanodevices.
Oded Galor, Professor, Department of Economics
Economic Development and Human Evolution
This interdisciplinary research will explore the dynamic interaction between human evolution and the process of economic development. It will advance a unified evolutionary growth theory that will generate hypotheses about the interplay between the process of development and human evolution, shedding new light about the origin of the observed evolution of health, life expectancy, human capital, and risk aversion since the Neolithic revolution.
Katrina L. Gamble, Assistant Professor, Department of Political Science
Having a Seat at the Table: Race, Representation and Deliberation in the United States Congress
The project seeks to examine the possible link between racial diversity in Congress and expanded political deliberations. Does the presence of black legislators allow for more diverse political views to be discussed in Congress? More blacks and Latinos were elected to Congress in 2004 than ever before, making the 109th Congress the most diverse in history of the United States. Consensus on how increased diversity affects policy outcomes seems to evade scholars and political analysts and therefore efforts to understand how to provide marginalized constituencies with equitable political representation remain a fertile area for democratic scholarship. This study will contribute to broader discussions about the value of descriptive representation of democratic ideals.
Robert E. Gramling, Assistant Professor, Department of Family Medicine
Family history, inflammatory status and coronary heart disease mortality
A family history of early-onset heart disease is a strong predictor of coronary heart disease yet the mechanism underlying this complex association is poorly understood. Family history is associated with inflammatory status and inflammation predicts cardiac-related death. This project will investigate the degree to which baseline inflammatory status explains this relationship between family history and cardiac death.
Karl Jacoby, Associate Professor, Department of History
Shadows at Dawn: The Camp Grant Massacre and the Borderlands of History
On April 30, 1871, a group of Mexican Americans, Anglos, and Tohono O’odham Indians attacked a newly created Apache reservation in Arizona Territory known as Camp Grant. Striking at dawn, the attackers killed some 150 sleeping Apaches, all but eight of them women or children. This premeditated assault remains among the largest mass murders of women and children in United States history. In spite of the event’s significance, however, there exists no scholarly history of the “Camp Grant Massacre.” Jacoby’s goals in writing the first such study are to recapture an incident now unknown to most Americans and to grapple with one of the most difficult questions of the historical enterprise. How does one narrate the history of an atrocity?

RobAuCon – Autonomous Control of Robots from Demonstration
Jenkins and Sellmann will conduct research into methods for the autonomous control of robot teams with strategies learned from human demonstration. The team, which includes Brown students, will focus on a specific application domain, robot soccer, to further research in robot learning from demonstration, time-critical combinatorial optimization, and their application to multi-robot task allocation.
