RACISM AND CANCER PREVENTION: THE ROLE OF PERCEIVED RACISM AND RACE-BASED RESIDENTIAL SEGRETATION ON BEHAVIORAL CANCER RISK PROFILES
(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
(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 ... -
Raman spectroscopy of isogenic breast cancer cells derived from organ-specific metastases reveals distinct biochemical signatures
(2015-05-01)Characterizing the subtle divergence of the metastatic lesions from the primary tumor is critical to understanding organ-specific adaptations that regulate further disease progression as well as the development of targeted ... -
RANDOM DOT PRODUCT GRAPHS A MODEL FOR SOCIAL NETWORKS
(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
(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
(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 ... -
RATIONAL IDEALOGUES OR ORTHODOX FANATICS? DISCERNING IDEOLOGY’S ROLE IN TERRORIST ORGANIZATION BEHAVIOR
(2015-01-28)There have long been divergent perceptions among scholars and policymakers regarding the relevance of a terrorist organization’s ideology to its actual decision making process. Some observers believe that terrorist ... -
RBM24 IS ESSENTIAL FOR NORMAL EARLY EMBRYONIC DEVELOPENT
(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 ... -
RE-THINKING MARITIME RISK: LINKING PIRACY, GLOBAL SHIPPING AND PORTS –AND- WHAT CRUISE/FERRY TERMINALS CAN LEARN FROM AIRPORTS
(2014-12-11)This thesis addresses two issues related to maritime risk. The first concerns recognizing high-volume shipping destined for U.S. ports initially journeys through foreign waters and ports where crime, piracy and terrorism ... -
REACTIONS OF HEME CATALYSTS AT NANOCRYSTALLINE TiO2 THIN FILM INTERFACES WITH ORGANOHALIDE POLLUTANTS
(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 ... -
The readiness, need for, and effect of mhealth interventions to improve immunization timeliness and coverage in rural western Kenya
(2014-12-23)Background: As mobile phone ownership levels grow globally, opportunities to target hard-to-reach populations through mobile-health technologies become more realistic. In a rural Kenyan population, this dissertation seeks ... -
Real Johnson-Wilson Theories and Computations
(Johns Hopkins UniversityUSA, 2016-03-22)Our main result is a computation of ER(n)^*(CP^\infty), the Real Johnson-Wilson cohomology of CP^\infty, for all n. We apply techniques from equivariant stable homotopy theory to the Bockstein spectral sequence. We produce ... -
Real-time Neuromorphic Visual Pre-Processing and Dynamic Saliency
(Johns Hopkins UniversityUSA, 2017-03-24)The human brain is by far the most computationally complex, efficient, and reliable computing system operating under such low-power, small-size, and light-weight specifications. Within the field of neuromorphic engineering, ... -
Realist Constructivism: Understanding Foreign Policy Intent
(2014-09-18)International Relations theory is a guide for understanding state behavior, which is especially important when dealing with potentially threatening countries whose intentions are difficult to decipher due to a perceived ... -
THE REALIST LIBERAL DEMOCRACY AND ITS POLICIES TOWARD INDIVIDUAL LIBERTIES
(2015-06-18)When the Arab Spring began in late 2010 and continued into 2011, a rash of debate erupted in political science and international theory regarding the likelihood of a wave of liberal democracy spreading throughout the Middle ... -
RECALIBRATING AMERICA’S FLAWED APPROACH TO DRONE WARFARE
(Johns Hopkins UniversityUSA, 2015-09-18)Unmanned aerial vehicles—widely referred to as “drones”—are a key instrument of American foreign policy. Yet, despite their importance, limited scholarship has been devoted to assessing the effectiveness of drone strikes ... -
Receptive Autonomy: A Psychoanalytic Ethics of Creative Discontent
(Johns Hopkins UniversityUSA, 2017-02-09)In contemporary political theory, the concept of autonomy generally signifies a liberal notion of rational choice and non-dependence. Theorists critical of liberalism often conceive of autonomy as inherently bound to a ... -
