The artist discusses her Bachelor of Fine Arts Exhibition, Confessions, held at the Tipton Gallery, from November 14th to November 25th. The exhibit portrays how the artist responds to issues such as organized religion, war, and politics. Being drawn to art from the Renaissance to Baroque era, the work encorporates an "old world" aesthetic, also with an emphasis on Gothic architecture.

This thesis is a picture of my journey as an educator. I taught at the University level from Fall 2001 – Summer 2006 before I became a graduate student at Virginia Commonwealth University in Theatre Pedagogy where I continued to teach until 2008. My education and real life experiences over the last seven plus years have contributed to my teaching methodology which is ever evolving. There were several trials and tribulations as I progressed as an educator and this is an exploration of my experience teaching in the BA and BFA curriculums.

Over the years, RFID (radio frequency identification) technology has gained popularity in a number of applications. The decreased cost of hardware components along with the recognition and implementation of international RFID standards have led to the rise of this technology.

Abstract:
Eukaryotic genomes are highly organized and packaged into chromatin, a complex structure formed of proteins and DNA, in which the basic repeating unit is the nucleosome. Chromatin can be arranged in condensed or relaxed structures influencing accessibility of proteins that regulate transcription, replication, recombination and repair. One class of transiently chromatin-associated proteins is the High-Mobility Group (HMG) protein family. HMG proteins are subdivided into three subgroups: HMGA, HMGB and HMGN. HMGN1, the subject of this study, is a prominent member of the HMGN (High-Mobility Group

Abstract:
This thesis is concerned with a variety of topics grouped together under the general theme of periodically driven atomic systems. Periodic driving is ubiquitous in most techniques used in atomic physics, be it laser cooling, ion trapping or AC magnetic fields. An in-depth understanding of the behaviour of such systems can be provided through Floquet theory which will develop as a central theme in the following chapters. The thesis is divided in two parts: neutral atoms, and ions and biomolecules. In the first part I discuss a new <sup>41</sup>K-<sup>87</sup>Rb mixture experiment, built during

Abstract:
Despite the historical associations of shared living with economically and socially marginalised populations, contemporary sharehouses in Japan are seen and marketed as a new foreign lifestyle import that offers an alternative to living alone or in the family home. Based primarily on nine months of intensive fieldwork during residence in a sharehouse, interviews with sharehouse professionals, and discourse analysis of marketing materials, the present work discusses the gaps and consonances amongst the promises set forth in sharehouse marketing, my housemates' desires and expectations, and the

Abstract:
This thesis discusses the unmaking of republican citizenship in colonial Algeria and the reverberations of this process in the metropole under the Third Republic, as well as demands and contestations by various populations in the colony concerning participation and rights. The attempt to establish a regime of privileges for settlers and to exclude the Muslim majority led politicians, jurists, and administrators to rely on religion and ethnicity as legal criteria to demarcate the boundaries of French citizenship. In their quest to legitimise the political exclusion of the Muslim population, pol

Abstract:
This thesis was a step forward in investigating the relationship between human reproductive health effects and endocrine-disrupting chemicals. These chemicals are commonly found in our environment, industries, homes, and food, and have been detected in the human population. In Australia, concentrations of some endocrine disrupting chemicals have decreased over time but are still detected in humans. By conducting multiple projects including a cross-sectional study using follicular fluid, a health risk assessment using blood serum samples, and interpretation of Global Burden of Disease data, the

Abstract:
Problemställning och syfte: Bromerade flamskyddsmedel (BFR) används i många varor och produkter. Polybromerade difenyletrar (PBDEs) är en av dessa och deras kemiska struktur liknar den i miljögiftet PCB och kan på samma sätt lagras upp i miljön samt skada människor och djur. På arbetsplatser där BFR förekommer riskerar medarbetarna att exponeras. I den här studien har olika BFR undersökts i samband med servicearbete på flygplan. Målet har varit att jämföra förekomsten i damm och luft, samt blod (serum) med resultat från tidi­gare studier. Metod: Damm- och luftprovtagning har genomförts vid oli

Abstract:
Clustering with the framework suggested by Bradley, Fayyad and Reina allows for great scalability. However, practical challenges appear when applying the framework. One of the challenges is to define model parameters. This includes defining the number of clusters (K). Understanding how parameter values affect the final clustering may be challenging even with insight into the algorithm. Automating the clustering would allow for a more widespread use. The research question is thus: How could an automated process for clustering with BFR be defined and what results could such a process yield? A ta

Abstract:
Brominated flame retardants (BFRs) have been used in a variety of consumer products to enhance their fire safety. This has resulted in exposure of the environment, wildlife and humans causing risks of endocrine disruption. The use restrictions of many BFRs have resulted in the introduction of other brominated chemicals (emerging BFRs) on the market. Humans are exposed to BFRs primarily via diet and dust ingestion, but the importance of the different exposure pathways has scarcely been studied. Children in particular have not been studied well due to lack of biomonitoring data. In this thesis,
