Asphalt rubber (AR), which is prepared by blending crumb rubber and bitumen, provides various advantages, including superior rutting resistance, lower road-tire noise and longer service life. However, contractors have expressed concerns regarding its poor storage stability, which in turn limits its wider application. This study aims to address the storage stability concern by incorporating nano-montmorillonite (nanoclay). Three types of nanoclay were dispersed into hot AR binder by high shear blending. The rheological properties of nanoclay-crumb rubber modifier (CRM)-modified bitumen were evaluated through Superpave performance grade (PG) tests and the storage stability was characterized by measuring the difference in softening points …

Physical Activity During Pregnancy And Birth Outcomes In South Carolina 2009-2015, Andrew Tyler Broadway

Theses and Dissertations

Physical activity is known to be beneficial to adults in general, including pregnant women, but the literature on physical activity and neonatal outcomes has been inconsistent. Few studies have differentiated between physical activity prior to pregnancy and during pregnancy to see whether the typical beneficial effect is not due to having a more active lifestyle in general. The Pregnancy Risk Assessment Monitoring System (PRAMS) is a national cross-sectional surveillance system. Our data from SC PRAMS included 6391 respondents and was weighted to be representative of population of pregnant women that delivered in the state. We excluded births that were not …

Faculty Publications

There is competing evidence that plasmacytoid dendritic cells (pDC), the most potent source of IFN-I, may initiate psoriasis. We targeted pDC function using the slc15a4 loss-of-function mouse whose pDC are unresponsive to TLR agonists. slc15a4 treated with the topical TLR7-agonist imiquimod (IMQ) demonstrated decreased epidermal thickening 24 hours post-treatment which was more pronounced by day 5 as compared to wildtype mice. These findings were specific to the acute IMQ model and not the protracted IL23 model that drives inflammation downstream of TLR activation. Systemically, slc15a4 was required for IMQ-induced weight loss and cutaneous accumulation of CD4+ and Siglec H+, but …

Pandemic and seasonal influenza viruses can be transmitted through aerosols and droplets, in which viruses must remain stable and infectious across a wide range of environmental conditions. Using humidity-controlled chambers, we studied the impact of relative humidity on the stability of 2009 pandemic influenza A(H1N1) virus in suspended aerosols and stationary droplets. Contrary to the prevailing paradigm that humidity modulates the stability of respiratory viruses in aerosols, we found that viruses supplemented with material from the apical surface of differentiated primary human airway epithelial cells remained equally infectious for 1 hour at all relative humidities tested. This sustained infectivity was …

Exploring The Impact Of Efficacy Messages On Cessation-Related Outcomes Using Ecological Momentary Assessment, Victoria Lambert, Stuart G. Ferguson, Jeff Niederdeppe, David Hammond, James W. Hardin, Jim Thrasher

Faculty Publications

Introduction:
Observational studies indicate that cigarette package inserts with efficacy messages about the benefits of quitting (i.e. response efficacy) and recommendations for successful cessation increase smokers’ self-efficacy to quit and promote sustained cessation. However, the effects of inserts with such efficacy messages have not been studied using experimental designs. This study used ecological momentary assessment (EMA) to assess smokers’ responses to efficacy inserts.

Material and Methods:
In a randomized case-crossover study among smokers from the United States (n=23), participants received a one-week supply of cigarettes with efficacy inserts and a one-week supply without any inserts, and were randomized to use …

Suspended aqueous aerosol droplets (<50 μm) are microreactors for many important atmospheric reactions. In droplets and other aquatic environments, pH is arguably the key parameter dictating chemical and biological processes. The nature of the droplet air/ water interface has the potential to significantly alter droplet pH relative to bulk water. Historically, it has been challenging to measure the pH of individual droplets because of their inaccessibility to conventional pH probes. In this study, we scanned droplets containing 4-mercaptobenzoic acid–functionalized gold nanoparticle pH nanoprobes by 2D and 3D laser confocal Raman microscopy. Using surface-enhanced Raman scattering, we acquired the pH distribution inside approximately 20-μm-diameter phosphate-buffered aerosol droplets and found that the pH in the core of a droplet is higher than that of bulk solution by up to 3.6 pH units. This finding suggests the accumulation of protons at the air/water interface and is consistent with recent thermodynamic model results. The existence of this pH shift was corroborated by the observation that a catalytic reaction that occurs only under basic conditions (i.e., dimerization of 4-aminothiophenol to produce dimercaptoazobenzene) occurs within the high pH core of a droplet, but not in bulk solution. Our nanoparticle probe enables pH quantification through the cross-section of an aerosol droplet, revealing a spatial gradient that has implications for acid-base–catalyzed atmospheric chemistry.

Disclosure Of Homosexual Behaviors To Healthcare Providers And Uptake Of Hiv Testing For Men Who Have Sex With Men: A Systematic Review., Shan Qiao Ph.D., Guangyu Zhou, Xiaoming Li

Faculty Publications

To promote HIV-testing and offer optimal care for men who have sex with men (MSM), health-care providers (HCPs) must first be aware of their patients’ sexual behaviors. Otherwise, HCPs may overlook MSM’s risks for HIV infection and their special health-care needs. For MSM, reporting their same-sex behaviors to HCPs (disclosure to HCPs) may promote their linkage to HIV prevention and treatment cascade and improve their health outcomes. No literature review has been conducted to examine the relationship between disclosure to HCPs and uptake of HIV-testing among MSM. The current study reviewed and synthesized findings from 29 empirical studies published in …

Scale development and validation are critical to much of the work in the health, social, and behavioral sciences. However, the constellation of techniques required for scale development and evaluation can be onerous, jargon-filled, unfamiliar, and resource-intensive. Further, it is often not a part of graduate training. Therefore, our goal was to concisely review the process of scale development in as straightforward a manner as possible, both to facilitate the development of new, valid, and reliable scales, and to help improve existing ones. To do this, we have created a primer for best practices for scale development in measuring complex phenomena. …

The Importance Of Interdisciplinarity: Redefining The Health Belief Model, Ross F. Lordo May 2018

The Importance Of Interdisciplinarity: Redefining The Health Belief Model, Ross F. Lordo

Senior Theses

Throughout academia, there lacks an existence of a commonly utilized multicomponent and interdisciplinary approach in understanding our outside world. This thesis provides an analysis of the current state of interdisciplinarity and the need to develop interdisciplinary theory. Through this effort, the researcher utilizes the health belief model as a framework that is severely limited in applicable scope due to its constructs. Contrastingly, systems theory and game theory are validated as examples of theories with an interdisciplinary nature. Through the coding of the literature pertaining to the qualitative characteristics of the health belief model, game theory and systems theory, guidelines in …
