Energy From Active Galactic Nuclei And The Effects On Host Spiral Galaxies, Amanda Schilling

Graduate Theses and Dissertations

I have investigated the energy output of active galactic nuclei (AGN) in order to understand how these objects evolve and the impact they may have on host galaxies. First, I looked at a sample of 96 AGN at redshifts $z \sim 2, 3,$ and $4$ which have imaging and thus luminosity measurements in the $griz$ and $JHK$ observed wavebands. For these galaxies, I have co-epochal data across those bands which accounted for variability in AGN luminosity. I used the luminosity measurements in the five bands to construct spectral energy distributions (SED) in the emitted optical-UV bands for each AGN. I …

Developing Algorithms For Quantifying The Super Resolution Microscopic Data: Applications To The Quantification Of Protein-Reorganization In Bacteria Responding To Treatment By Silver Ions, Sai Divya Challapalli

Graduate Theses and Dissertations

Histone-like nucleoid structuring proteins (HNS) play significant roles in shaping the chromosomal DNA, regulation of transcriptional networks in microbes, as well as bacterial responses to environmental changes such as temperature fluctuations. In this work, the intracellular organization of HNS proteins in E. coli bacteria was investigated utilizing super-resolution fluorescence microscopy, which surpasses conventional microscopy by 10–20 fold in spatial resolution. More importantly, the changes of the spatial distribution of HNS proteins in E. coli, by addition of silver ions into the growth medium were explored. To quantify the spatial distribution of HNS in bacteria and its changes, an automatic method …

Seasonality And Management Of Spotted Wing Drosophila On Berry Crops And Wild Hosts In Arkansas, Lizabeth Rubi Herrera

Graduate Theses and Dissertations

Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura) is a serious invasive pest of small fruit production in North and South America and Europe since 2008.

HearNPV spread 200 feet in 3 fields, and was …

The Diffusion Of Veterans Treatment Courts: An Examination Of Political, Social, And Economic Determinants At The County Level, Eric D. Button

Graduate Theses and Dissertations

In 2008, leading U.S. counties adopted innovative treatment courts specializing in the unique needs of veterans with substance abuse and other legal issues. Since then, pro-veteran advocacy has aided in the continued diffusion of additional veterans treatment courts (VTCs), with more than 300 county and state-level VTCs currently operating in 46 states across the country. Though the lens through which veterans are viewed may be positive in the public eye, institutional support for these wayward veterans appears to vary across levels of government; therefore, while some posit the increased social utility of budget-friendly VTCs, others suggest that VTCs offer favorable …

Effects Of Pre-Chiller Temperature On The Microbial Ecology Of Whole Bird Carcass Rinses, Rachael Elizabeth Blevins

Graduate Theses and Dissertations

Upon entering a poultry processing facility, birds are already contaminated with a variety of microorganisms. It is the responsibility of the processor to reduce these numbers to deliver a wholesome product to customers. This is not an easy task as there are ample opportunities for further microbial contamination. Some of these opportunities are obvious. For example, any areas where contaminants could be washed off one bird and onto another are always an area for concern, i.e. the scalder or the chiller. There are numerous opportunities for contamination that are not so obvious. These incidents of contamination are not necessarily due …

A Molecular Diagnostic Survey Of Pathogens And Parasites Of Honey Bees, Apis Mellifera L., From Arkansas And Oklahoma, Dylan Cleary

Graduate Theses and Dissertations

The health and viability of colonies of the honey bee, Apis mellifera, in the United States have fluctuated dramatically over the past decade. This poses a substantial threat to agricultural production in this country. Currently, no single factor has been identified for this decline. Rather, it has been suggested that the interaction between multiple biotic and abiotic stressors may be responsible. Among these factors are pesticides, habitat loss, climate and weather, parasites and pathogens, and colony management techniques. For this reason, it is important to examine the prevalence of honey bee parasite and pathogen infection at the state level in …

“I Am The Handmaid Of The Lord”: The Spiritual Development Of Mary Ward Amidst English Catholic Clerical Crisis, 1585 – 1630, Alyson Borowczyk

History Theses

In late Tudor and Stuart England, exercising one’s Catholic beliefs could potentially lead to a martyr’s reward. Since the practice of Catholicism was clandestine, homes became parishes within themselves, with the woman of the house serving as pastoral administrator. She was charged with taking care of the priests she was illegally harboring, and she was also responsible for educating the young in the ways of the Faith to ensure it did not die with her generation. These were indeed subversive acts, because she defied the State and its laws. Mary Ward, foundress of the Institute of the Blessed Virgin Mary, …

How Does Increasing The Power Of Retrieval Cues Change The Experience Of Remembering?, Oyku Uner

Arts & Sciences Graduate Student Theses and Dissertations

Increasing the power of retrieval cues typically enhances recall and recognition. Is this driven by remembering, knowing, or both? The current study used the remember/know paradigm in different recall tasks that manipulated the power of retrieval cues. In the first two experiments, participants studied words in a semantic or phonetic context, and were tested in one of these contexts, resulting in two match and two mismatch conditions. Participants recalled more in the match conditions, and this was driven by remembering. In the third experiment, participants studied multiple word lists and were tested immediately after each list with varying number of …

Do Learners Have Insight Into The Levels Of Processing Effect? Exploring Unresolved Levels Of Processing Phenomena With Judgments Of Learning, Elif Eylul Tekin

Arts & Sciences Graduate Student Theses and Dissertations

The levels of processing (LOP) effect shows that semantic processing leads to better retention than other types of processing. The effect is routinely obtained on many types of tests, yet, to this day, its mechanisms are still debated and it is poorly understood. In two old/new recognition experiments, I investigated potential explanations as to why the LOP effect occurs under intentional learning instructions. I asked a) whether subjects were aware of the LOP effect while they were studying the material, b) whether explicitly encouraging subjects to study the words with their idiosyncratic strategies would eliminate the effect, and c) whether …

Anti-Icing Properties Of Femtosecond Laser Surface Processed Material, Ryan James Bell

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

In this thesis, the use of femtosecond laser surface processing (FLSP) to enhance the anti-icing properties of a commonly used aircraft alloy, Al 7075-O Clad is described. By changing the surface morphology through FLSP and the surface chemistry through siloxane vapor deposition, the wettability of Al 7075-O Clad was altered.

Condensation and the subsequent freezing of condensates on FLSP Al 7075-O Clad was studied. Both structure height and surface wettability were shown to play a role in the delay of freezing. Freezing occurred on the FLSP superhydrophilic surface faster than on the unprocessed Al 7075-O Clad surface, however, freezing was …

Neutrosophic Hough Transform, Florentin Smarandache, Umit Budak, Yanhui Guo, Abdulkadir Sengur

Branch Mathematics and Statistics Faculty and Staff Publications

Hough transform (HT) is a useful tool for both pattern recognition and image processing communities. In the view of pattern recognition, it can extract unique features for description of various shapes, such as lines, circles, ellipses, and etc. In the view of image processing, a dozen of applications can be handled with HT, such as lane detection for autonomous cars, blood cell detection in microscope images, and so on. As HT is a straight forward shape detector in a given image, its shape detection ability is low in noisy images. To alleviate its weakness on noisy images and improve its …

Vkse-Mo: Verifiable Keyword Search Over Encrypted Data In Multi-Owner Settings, Yinbin Miao, Jianfeng Ma, Ximeng Liu, Junwei Zhang, Zhiquan Liu

Research Collection School Of Computing and Information Systems

Searchable encryption (SE) techniques allow cloud clients to easily store data and search encrypted data in a privacy-preserving manner, where most of SE schemes treat the cloud server as honest-but-curious. However, in practice, the cloud server is a semi-honest-but-curious third-party, which only executes a fraction of search operations and returns a fraction of false search results to save its computational and bandwidth resources. Thus, it is important to provide a results verification method to guarantee the correctness of the search results. Existing SE schemes allow multiple data owners to upload different records to the cloud server, but these schemes have …

A Novel Density Peak Clustering Algorithm Based On Squared Residual Error, Milan Parmar, Di Wang, Ah-Hwee Tan, Chunyan Miao, Jianhua Jiang, You Zhou

Research Collection School Of Computing and Information Systems

The density peak clustering (DPC) algorithm is designed to quickly identify intricate-shaped clusters with high dimensionality by finding high-density peaks in a non-iterative manner and using only one threshold parameter. However, DPC has certain limitations in processing low-density data points because it only takes the global data density distribution into account. As such, DPC may confine in forming low-density data clusters, or in other words, DPC may fail in detecting anomalies and borderline points. In this paper, we analyze the limitations of DPC and propose a novel density peak clustering algorithm to better handle low-density clustering tasks. Specifically, our algorithm …

Black Australia ‘Writes Back’ To The Literary Traditions Of Empire, Danica Čerče

CLCWeb: Comparative Literature and Culture

I In her article "Black Australia 'Writes Back' to the Literary Traditions of Empire" Danica Čerče discusses the verse of Australian Indigenous authors Romaine Moreton and Alf Taylor, notable for the overt objection to the institutional and historical processes. These have enabled and maintained the dominant position of those identified as white on the one hand, and the concomitant political, economic, and cultural subordination of Indigenous Australians on the other. Focused on strategies and poetic devices used by the two poets to engage non-Indigenous readers in the experience of their writing, the article examines how the rhetoric of their critique …

Khaled Hosseini’S A Thousand Splendid Suns As A Child-Rescue And Neo-Orientalist Narrative, Abdullah M. Al-Dagamseh, Olga Golubeva

CLCWeb: Comparative Literature and Culture

In their article "Khaled Hosseini's A Thousand Splendid Suns as a Child-Rescue and Neo-Orientalist Narrative" Abdullah Mohammad Dagamseh and Olga Golubeva argue that the novel contrib­utes to hegemonic Eurocentric discourse by showing the superiority and benevolence of the West. In contrast to existing scholarly focus on Hosseini's portrayal of female characters, this article highlights how children of both sexes are represented. The authors' aim is to show how Hosseini's picture of children affected by war contributes to the neo-Orientalist and child-rescue discourses, jus­tifying the foreign involvement in Afghanistan's internal affairs. Moreover, Dagamseh and Golubeva argue that the use of universal …

Violence Against Children In Nyarugusu Refugees Camp: Reporting And Perceptions Across Generations, Erin K. Fletcher, Seth R. Gitter, Savannah Wilhelm

Himalayan Research Papers Archive

There are over two million displaced children worldwide living in established refugee camps. Many of these children have escaped violent conflict in their country, but still are victims of violence within settlement camps. Little is known about the social norms around violence in these camps particularly in regards to reporting. We study this issue using a sample of over 300 child parent pairs in Nyarugusu camp in Tanzania. The camp consists of over 130,000 refugees mainly from Burundi and the Democratic Republic of Congo. We find that parents have limited acceptance of physical violence and essentially no acceptance of sexual …
