    • Race and Romantic Visions: A Tragic Reading 

      Culver, Adam (Johns Hopkins UniversityUSA, 2015-05-08)
      My dissertation explores a set of creative intersections between romanticism, black political thought, and Nietzschean philosophy. In so doing it asks two overarching questions. First, how do different ethical theories, ...
    • Racial Politics and Social Policy in Urban Canada

      The dissertation presents findings from a comparative study of urban policies the provincial governments of Quebec and Ontario introduced simultaneously, yet independently, in the year of 2006. Its central purpose is to ...
    • Racial School Segregation and the Transition to College 

      Warkentien, Siri (Johns Hopkins UniversityUSA, 2015-06-24)
      Prior studies generally find that attending black-segregated schools is detrimental across a range of academic outcomes, but much research on the causes and consequences of school segregation rely on single time-point ...
    • RACISM AND CANCER PREVENTION: THE ROLE OF PERCEIVED RACISM AND RACE-BASED RESIDENTIAL SEGRETATION ON BEHAVIORAL CANCER RISK PROFILES 

      Shariff-Marco, Salma (Johns Hopkins University, 2008-04-24)
      Problem statement: Cancer is a significant public health problem in the United States; since 1999 cancer has been the leading cause of death among those 85 years and younger. Racial/ethnic disparities in cancer exist. ...
    • Radiation-driven, geometrically thick, dusty obscuration in active galactic nuclei 

      Chan, Chi Ho; 0000-0001-5949-6109 (Johns Hopkins UniversityUSA, 2016-10-05)
      Substantial evidence points to dusty, geometrically thick tori obscuring the central engines of active galactic nuclei (AGNs), but so far no mechanism satisfactorily explains why cool dust in the torus remains in a puffy ...
    • RADICAL SAM ENZYMES IN THIENAMYCIN BIOSYNTHESIS 

      Marous, Daniel R (Johns Hopkins UniversityUSA, 2015-12-07)
      Despite its broad anti-infective activity, the biosynthesis of the paradigm carbapenem antibiotic, thienamycin, remains largely unknown. Apart from the first two biosynthetic steps shared with a simple carbapenem, the ...
    • RANDOM DOT PRODUCT GRAPHS A MODEL FOR SOCIAL NETWORKS 

      Nickel, Christine Leigh Myers (Johns Hopkins University, 2008-02-01)
      We develop a new set of random graph models. The motivation for these mod- els comes from social networks and is based on the idea of common interest. We represent a social network as a graph, in which vertices correspond ...
    • RANDOM DRIFT: CHANCE AND EXPLANATION IN EVOLUTIONARY BIOLOGY 

      Goldstein, Adam (Johns Hopkins University, 2006-08-03)
      The central claim for which I argue in this dissertation is that there are important phenomena that occur by random drift that evolutionary biologists explain using a strategy I term “process explanation.” This claim ...
    • Random Graph Modeling and Discovery 

      Hallonquist, Neil F. (Johns Hopkins UniversityUSA, 2015-10-16)
      In the first part of this thesis, we present a general class of models for random graphs that is applicable to a broad range of problems, including those in which graphs have complicated edge structures. These models need ...
    • RAPID DETECTION OF VIABLE BACTERIA IN AGRICULTURAL WASH WATERS – A DROPLET-BASED APPROACH 

      Harmon, James Brian; 0000-0001-5661-6427 (Johns Hopkins UniversityUSA, 2017-10-31)
      Foodborne illness is a significant public health concern worldwide, with a global burden of disease comparable to HIV/AIDS, malaria and tuberculosis. The World Health Organization estimated there were approximately 2 ...
    • Rational Design of Peptide-Based Supramolecular Polymers as Functional Biomaterials 

      Lin, Yi-an (Johns Hopkins UniversityUSA, 2014-07-16)
      Ordered supramolecular polymers are one-dimensional (1D) nanostructures formed by spontaneous association of molecular building units through non-covalent interactions. The construction of supramolecular polymers, often ...
    • RAYONG OIL SPILL CLEANUP WORKERS EXPOSURE AND SYMPTOM ASSESSMENT 

      Ingviya, Thammasin; 0000-0002-8894-3817 (Johns Hopkins UniversityUSA, 2017-10-16)
      In July of 2013, a pipeline connecting an offshore oil platform to a tanker, operated by PTT Global Chemical (PTTGC), a corporation owned by the government of Thailand, leaked and caused crude oil to spill into the Sea of ...
    • RBM24 IS ESSENTIAL FOR NORMAL EARLY EMBRYONIC DEVELOPENT 

      Maragh, Samantha (Johns Hopkins University, 2014-02-12)
      Rbm24 was recently identified as a gene expressed during early mouse cardiac development (Miller et al., 2008). Due to its tightly restricted and persistent expression from formation of the cardiac crescent onwards and ...
    • REACTIONS OF HEME CATALYSTS AT NANOCRYSTALLINE TiO2 THIN FILM INTERFACES WITH ORGANOHALIDE POLLUTANTS 

      Ito, Tamae (Johns Hopkins University, 2007-03-23)
      Organohalide compounds are one of major pollutants on Environmental Protection Agency’s (EPA) contaminants candidate list (www.epa.gov.safewater). Chapter 1 represents the overview of environmental detoxification of ...
