Efficacy, Effort, And Cost Comparisons Of Trapping And Acetaminophen-Baiting For Control Of Brown Treesnakes On Guam, Larry Clark, Peter J. Savarie, John A. Shivik, Stewart W. Breck, Brian S. Dorr

United States Department of Agriculture Wildlife Services: Staff Publications

Brown treesnakes (Boiga irregularis) are an invasive species to the island of Guam. Because they have extirpated the native forest avifauna on Guam and are a threat to other Pacific islands, the development of efficient and cost-effective methods to control them is desired. We compared the efficacy, cost, and effort required to remove brown treesnakes on 6-ha plots in forest scrub on Guam, using 2 methods: trapping and poison baiting. Toxic baits consisted of dead neonatal mice adulterated with 80-mg acetaminophen. To assess efficacy, we used mark-recapture methods to estimate snake abundance on plots 12 days before and …

Toward A Comparative Approach To The Crime Of Genocide, Tatiana E. Sainati

Duke Law Journal

The annihilation of more than 1.5 million Cambodians at the hands of the Khmer Rouge is widely considered a quintessential case of genocide. Whether these atrocities meet the definition of genocide as a legal matter, however, remains unsettled. As of October 2012, the question of whether genocide occurred in Cambodia within the meaning of the 1948 United Nations Genocide Convention is pending before the Extraordinary Chambers in the Courts of Cambodia (ECCC). The ECCC will determine this question against the backdrop of an ongoing debate about the appropriate scope of the crime of genocide. This debate pits expansionists, who believe …

Neocolonialism And The Global Prison In National Geographic’S Locked Up Abroad, Casey Ryan Kelly

Department of Communication Studies: Faculty Publications

This essay examines the reformulation of colonial ideologies in National Geographic Channel’s Locked Up Abroad, a documentary program that chronicles the narratives of Westerner travelers incarcerated in foreign nations. An analysis of Locked Up Abroad evinces neocolonialism in contemporary media culture, including the historic association between dark-skin and savagery, the backwardness of the non-Western world, and the Western imperative to civilize it. The program’s documentary techniques and framing devices sustain an Otherizing gaze toward non-Western societies, and its portrayals elide a critical analysis of colonialism in its present forms. I advocate for neocolonial criticism to trace how NatGeo remains …

Improving Performance Of Solid State Drives In Enterprise Environment, Jian Hu

School of Computing: Dissertations, Theses, and Student Research

Flash memory, in the form of Solid State Drive (SSD), is being increasingly employed in mobile and enterprise-level storage systems due to its superior features such as high energy efficiency, high random read performance and small form factor. However, SSD suffers from the erase-before-write and endurance problems, which limit the direct deployment of SSD in enterprise environment. Existing studies either develop SSD-friendly on-board buffer management algorithms, or design sophisticated Flash Translation Layers (FTL) to ease the erase-before-write problem. This dissertation addresses the two issues and consists of two parts.

The first part focuses on the white-box approaches that optimize the …

Structural, Spectroscopic, And Electrochemical Properties Of Nonheme Fe(Ii)-Hydroquinonate Complexes: Synthetic Models Of Hydroquinone Dioxygenases, Amanda E. Baum, Heaweon Park, Denan Wang, Sergey V. Lindeman, Adam T. Fiedler

Chemistry Faculty Research and Publications

Using the tris(3,5-diphenylpyrazol-1-yl)borate (^Ph2Tp) supporting ligand, a series of mono- and dinuclear ferrous complexes containing hydroquinonate (HQate) ligands have been prepared and structurally characterized with X-ray crystallography. The monoiron(II) complexes serve as faithful mimics of the substrate-bound form of hydroquinone dioxygenases (HQDOs) – a family of nonheme Fe enzymes that catalyze the oxidative cleavage of 1,4-dihydroxybenzene units. Reflecting the variety of HQDO substrates, the synthetic complexes feature both mono- and bidentate HQate ligands. The bidentate HQates cleanly provide five-coordinate, high-spin Fe(II) complexes with the general formula [Fe(^Ph2Tp)(HL^X)] (1X), where HL^X is …

Cost Benefit Analysis Of The Federal Tax Credit For Purchasing An Electric Vehicle, William Fuqua

Theses

This paper will present the results of a cost-benefit analysis performed to determine the public benefits of the $7500 federal tax credit for purchasing an electric vehicle. A cost benefit ratio including air pollution, carbon dioxide emissions, and oil dependence as components was created and applied to every county in the continental United States. The results suggest that the current tax credit is too high since it does not create $7500 worth of public benefits using the benefits included in the analysis. Benefits vary regionally due to sources of electricity generation and existing air pollution levels with counties in the …

Modeling Leakage Currents In Metal Insulator Metal Structures With High K Materials, Priyamvada Maleeswaran

Electrical & Computer Engineering Theses & Dissertations

Various products such as personal computers, cellular phones and mobile devices require high speed and low power consumption. Such improvements have been attained by minimizing physical dimensions of electronic devices, leading to high density integration of transistors and capacitors on integrated chips (]Cs). However, as a consequence of down-scaling device dimensions, tunneling of electrons through thin gate oxides (SiO₂) increases, leading to increased static power leakage. This constitutes wastage in power, and for the case of memory applications necessitates faster refresh cycles. In order to overcome such issues, high-k materials (such as HfO₂ and ZrO₂) …

Evolution On The Hawaiian Hotspot: Biogeography And Divergence Time Estimation Of Kadua (Rubiaceae), Kenneth L. Parker

Biological Sciences Theses & Dissertations

Recent studies on the colonization time of Hawaiian plant and animal lineages have suggested certain lineages arrived to the archipelago before the formation of the extant islands. Kadua, a recently resurrected genus, is mostly endemic to the Hawaiian Archipelago, with many member taxa autochthonous to individual islands. This work investigates the colonization time of Kadua to the Hawaiian Islands. Sequence analyses of the quickly evolving nuclear regions ITS, ETS and 5s-NTS regions for 20 Hawaiian and 7 French Polynesian species of Kadua were used to create dated phylogeny calibrated with island ages. The phylogeny suggests a single colonization of Hawaii …

The Writings Of John Of Damascus During The First Iconoclast Controversy, Alejandro Sills , '13

Senior Theses, Projects, and Awards

The subject of this inquiry is Saint John of Damascus, an eighth-century Syrian monk who wrote against Byzantine Iconoclasm. Through a study of his writings and the works that he cited, together with an investigation into modern scholarship, this thesis argues that his claim for the custom of image veneration as a legitimate part of Christian worship from its earliest days is sound. In the process, the paper looks into the evolution of historiography surrounding the subject, with implications for how to approach ancient sources.
