Leprosy and tuberculosis are age-old diseases that have tormented mankind and left behind a legacy of fear, mutilation, and social stigmatization. Today, leprosy is considered a Neglected Tropical Disease due to its high prevalence in developing countries, while tuberculosis is highly endemic in developing countries and rapidly re-emerging in several developed countries. In order to eradicate these diseases effectively, it is necessary to understand how they first originated in humans and whether they are prevalent in nonhuman hosts which can serve as a source of zoonotic transmission. This dissertation uses a phylogenomics approach to elucidate the evolutionary histories of the ...

A comprehensive and systematic investigation on the diffusion and phase behaviors of nanoparticles and macromolecules in two component liquid-liquid systems via Molecule Dynamic (MD) simulations is presented in this dissertation. The interface of biphasic liquid systems has attracted great attention because it offers a simple, flexible, and highly reproducible template for the assembly of a variety of nanoscale objects. However, certain important fundamental issues at the interface have not been fully explored, especially when the size of the object is comparable with the liquid molecules. In the first MD simulation system, the diffusion and self-assembly of nanoparticles with different size, ...

Many animals thermoregulate to maximize performance. However, interactions with other animals, such as competitors or predators, limit access to preferred microclimates. For instance, an animal may thermoregulate poorly when fighting rivals or avoiding predators. However, the distribution of thermal resources should influence how animals perceive and respond to risk. When thermal resources are concentrated in space, individuals compete for access, which presumably reduces the thermoregulatory performance while making their location more predictable to predators. Conversely, when thermal resources are dispersed, several individuals can thermoregulate effectively without occupying the same area. Nevertheless, interactions with competitors or predators impose a potent stress, ...

The ease of programmability in Software-Defined Networking (SDN) makes it a great platform for implementation of various initiatives that involve application deployment, dynamic topology changes, and decentralized network management in a multi-tenant data center environment. However, implementing security solutions in such an environment is fraught with policy conflicts and consistency issues with the hardness of this problem being affected by the distribution scheme for the SDN controllers. In this dissertation, a formalism for flow rule conflicts in SDN environments is introduced. This formalism is realized in Brew, a security policy analysis framework implemented on an OpenDaylight SDN controller. Brew has ...

The Maricopa County Heat Relief Network (HRN) is an ad-hoc partially self-organized network with some attributes of hierarchical coordination that forms each year to provide heat relief and hydration to residents in need by operating as cooling centers. These HRN organizations are a collection of non-profit, governmental and religious organizations. This dissertation looks at the HRN from a complexity governance perspective and engaged different parts of the network in interviews to learn more about their perspective in delivering heat relief. Further, participatory modeling with a prototype agent based model was done with the HRN coordinating agencies to look for emergent ...

Anxiety is one of the most common psychiatric disorders among children yet characterized by lower use of mental health services. Preventive efforts have demonstrated promise in the ability to reduce anxiety symptoms. However, as evidence-based interventions move into real-world settings, there is a need to systematically examine potential implementation factors that may affect program outcomes. The current study investigates the relations between different aspects of implementation and their effect on outcomes of a school-based preventive intervention targeting anxiety symptoms. Specifically, the study examines: (1) the measurement of quality of delivery, (2) specific relations among implementation components, (3) relations between these ...

ABSTRACT Much attention has been given to food justice in both academic and activist communities as of late. This project adds to the growing discourse around food justice by using creative works produced by members of the black community as case studies to analyze the relationship between food justice and the criminal justice system in their neighborhoods. In particular, this project examines two unique sources of creative expression from the black community. The first is the novel Been ‘Bout Dat, the story of a young boy Fattz, who is born into the projects of New Orleans and takes to street ...

The dissertation aims to provide a new perspective on the management of multi-tier supply chains. When a firm decides to buy a product from a supplier, the buying firm also needs to decide whether to use the supplier to make the lower-tier sourcing decisions or to make those decisions in-house. I call the former "supply chain-buy" and the latter "supply chain-make." If the choice is supply chain-buy, the buying firm releases sourcing control of its bill of materials (BOM) to the top-tier supplier and this supplier, then engages with the supply base to determine the BOM's supply chain. If the ...

In 2015, Germany was at the center of one of the largest displacements in history as upwards of a million refugees, many from Syria, fled to Germany. In my study, I was fortunate enough to spend three months living in Germany and interacting with Germans and refugees to hear their stories of positive intercultural interaction. Through the integration of Acculturation Theory (Berry, 1980), Cross-Cultural Adaptation Theory (Y.Y. Kim, 1980), and Coordinated Management of Meaning Theory (Pearce & Cronen, 1980) I conducted a qualitative research project where I interviewed 44 individuals representing both German citizens (25) and refugees (19) and collected ...

The transition to college has been identified as a vulnerable period for weight gain and the onset of obesity. Research has shown that the gut microbiota is different in obese compared to lean individuals, but a period of weight gain has never been studied in free-living individuals. The objective of this longitudinal, observational study was to assess the association between changes in the intestinal microbiota and weight-related outcomes in healthy college students living in on-campus dormitories at Arizona State University (n=39). Anthropometric measures and fecal samples were collected at the beginning and end of the school year, and microbial relative ...
