A Longitudinal Study of Adolescent Identity Development and Harmful Alcohol Use within a Racially/Ethnically Diverse Sample

Richie A. Kubilus & Alan Meca
The development of a clear sense of identity is a key developmental task in adolescence, and recent studies have found that identity synthesis and confusion are associated negatively and positively, respectively, to alcohol use. One alcohol expectancy - tension reduction - coincides with the hypothesis that identity development may prove to be a stressful developmental process, and may thereby serve as a motivator for adolescents to drink when a belief exists that stress can be...

Exosomes in Transmission and Blocking of Arthropod-Borne Flaviviral Infection and Pathogenesis

Wenshuo Zhou
Vector-borne diseases (VBDs) are human illnesses that are transmitted by vectors such as ticks, mosquitoes, and fleas. These arthropods transmit infectious pathogens such as viruses, protozoa, and bacteria, to humans during their blood-feeding. According to the estimation of the WHO, billions of people are affected by VBDs worldwide, and about 700,000 deaths are reported annually. Currently, very few reliable VBDs control approaches and vaccines available to treat various VBDs. Additionally, approaches to control arthropod’ proliferation...

Predicting the Likelihood of Dating Violence Perpetration in a Sample of Women: Unidirectional Versus Bidirectional Violence

Elaine Mae Murphy
Intimate partner violence (IPV) is a serious, pervasive problem affecting over 30% of young adults. Although early research focused on men as perpetrators, it is commonly found that women are just as likely, if not more likely, to perpetrate violence in relationships. Some studies have categorized violent couple dyads into unidirectional (perpetration only) or bidirectional violence (reporting both perpetration and victimization). The current study identified predictors of the two types of violent profiles, specifically among...

Role of Ixodes scapularis Sphingomyelinase-Like Protein (IsSMase) in Tick Pathogen Interactions

Pravesh Regmi
Arthropod-borne diseases are one of the major concerns throughout the world. Ixodes scapularis (hard tick) is one of the major vectors that is involved in arthropod-borne disease transmission. Langat virus (LGTV) is a model pathogen that is very similar to other medically important flaviviruses such as Tick-Borne Encephalitis virus (TBEV) and Powassan virus (POWV). Sphingomyelinase-like protein (IsSMase, a Sphingomyelinase D or SMase D, a venomous protein ortholog of spiders) is an enzyme present in ticks...

Students at a Crossroads: TA Development Across Pedagogical and Curricular Contexts

Cassandra Ann Book
A longstanding question in rhetoric and composition has been how to best educate composition graduate Teaching Assistants (TAs). Although many assume that writing centers are useful spaces for TAs to practice pedagogy and learn about writing processes in preparation for classroom teaching, recent scholarship complicates the claim that transfer from writing centers and/or practicums into composition classrooms is straightforward. Moreover, no study fully considers how the role of the writing center and teaching writing in...

Titian’s Poesie: The Visual Allegories of Morality and Religion

Holli M. Turner
Venetian painter Tiziano Vecellio, more commonly referred to as Titian, created a cycle of mythological paintings based on scenes from Ovid’s Metamorphoses for King Philip II of Spain. These works are often viewed through an eroticized lens due to this inclusion of nude mortals and goddesses. This thesis argues for the cycle’s moral and religious significance for Philip by utilizing comparative iconography, scholarly texts, and translated allegorical material.

Effects of Religion on Crime in Hampton Roads

Alaina Yvonne Bierdz
The influence of religion in society has been debated for hundreds of years. Renowned scholars like Max Weber and Émile Durkheim formed frameworks in which to study the relationship between religion and crime. The frameworks are based on the idea that religion promotes desirable behavior in society, while also controlling undesirable behavior. Although religion can be studied across many disciplines, this report examines the relationship between religion and crime. More specifically, the impact of religion...

Towards Dynamic Vehicular Clouds

Aida Ghazizadeh
Motivated by the success of the conventional cloud computing, Vehicular Clouds were introduced as a group of vehicles whose corporate computing, sensing, communication, and physical resources can be coordinated and dynamically allocated to authorized users. One of the attributes that set Vehicular Clouds apart from conventional clouds is resource volatility. As vehicles enter and leave the cloud, new computing resources become available while others depart, creating a volatile environment where the task of reasoning about...

Comparison of Two Separation Methods for Biological Particles: Field-Flow Fractionation (FFF) and Sucrose Density Gradients

Cody E. Garrison
Sucrose gradient centrifugation and Field-flow fractionation (FFF) are two different particle separation methods that overcome the problems of similar size microorganisms clumping together during standard filtration methods. FFF separates particles based on size and density via the parabolic velocity profile of laminar flow in a ribbon-like channel. The sucrose method separates particles via centrifugation in a density gradient. Both techniques worked well in separating eukaryotic from prokaryotic microbes, with the preferred method depending on the...
