Mobile traffic is expected to grow tenfold by 2019, topping 24 exabytes of monthly traffic and accounting for nearly half of all Internet traffic. This growth is driven by the increasing number of smart phones and tablets, and the data demands of high bandwidth services enabled by next-generation cellular networks...
The U.S. has 542,000 bridges that consume billions of dollars per year in construction, rehabilitation and maintenance funds and which are the lifelines of U.S. commerce. The 1992 ISTEA (fntermodal Surface Transportation Efficiency Act) mandates the implementation of a quantitative computerized bridge management system by I 996. A prime need...
Children come to understand race within a historically-established racial hierarchy, but they have the agency to accommodate or resist this establishment as they form their own racial identities. Previous research identified distinct narrative types that either reinforce existing societal structures (Master Narratives) or disrupt them (Alternative Narratives). The Counternarrative...
Romantic and sexual relationships are an integral part of human development, with implications for emotional, social, and physical well-being across the lifespan. However, what, when, and how we teach young people remain pertinent questions. Using a combination of interview data from 24 recent high-school graduates and survey data from a...
Metabolic conditions affect the developmental tempo of most animal species. Consequently, developmental gene regulatory networks (GRNs) must faithfully adjust their dynamics to a variable time scale. We find evidence that weak repressors of gene expression provide the necessary coupling between GRN output and cellular metabolism. Using a mathematical model that...
Objective: To evaluate documentation of cardiovascular (CV) risk factors and obesity management by pediatric cardiologists. Study design: Review of medical records of obese (≥95th body mass index percentile) 2–17 year-old children presenting to outpatient pediatric cardiology over 1 year. Subjects were categorized as: heart disease (HD) with increased risk for...
Many preventable behaviors contribute to adolescent mortality and morbidity. Non-adherence to preventive measures represents a challenge and has been associated with worse health outcomes in this population. The widespread use of electronic communication technologies by adolescents, particularly the use of text messaging (short message service, SMS) and mobile phones, presents...
Recently, much public attention has been focused on racial inequalities in who is subjected to exclusionary school disciplinary policies, and consequently, forced to miss hours of instruction. Over the past two decades, researchers have documented the disparate impacts that zero-tolerance policies have had on students of color, low-income students, and...
Microkinetic modeling is a powerful tool for creating dynamic and quantitative descriptions of complex systems. These detailed mechanistic models compliment experimental techniques and provide an ability to achieve deeper insights into chemical processes where numerous intermediates are highly reactive and difficult to quantify in the laboratory. This thesis discusses the...
