The Resource Curse And Peru: A Potential Threat For The Future?, Sergio Cruz

Master's Theses

What explains the ability of some countries to successfully use their natural resources towards development and economic growth while for others stagnation and impoverishment? The resource curse theory has helped economists explain this observation. This work examines how Peru has been able to produce strong economic growth in the last 20 years despite the economy’s strong dependence on its natural resource extractive industry. Peru has been able to avoid many of the pitfalls and traps that resource curse literature considers to be detrimental to economic growth. This article examines the resource based economies of four other countries (Venezuela, Chile, Nigeria, …

Microfinance Partnerships: A Bridge For Refugees, Megan Fielding

Master's Theses

My thesis examines the extension of microfinance to a refugee community; the objective focuses on economic assistance and a bridge to provide the required basic needs, as reported by the refugee population. With the global growth of refugees, the repositioning of refugees from either being cast aside as a potentially productive society or completely overlooked, is critical. Through my research in Ecuador, my thesis takes the viewpoint that refugees do, in fact, matter, and can become productive contributors to a society. The challenge that is presented in that viewpoint is: how do they become a part of a society?

Transforming The Current Thai Political Conflict To A Peaceful Society, Ranatchai Phumcharoen

Master's Theses

This study explores the current Thai political conflict which began in 2005 and continues in 2011. This conflict is different from the nation’s past political conflicts, which were conflicts between people and the government. On the contrary, the current conflict is a conflict between Thais who share different political ideologies. Many scholars have explained causes and effects of the conflict on Thai society. However, currently, only a few scholars have proposed solutions to the conflict. Therefore, this is a challenge in order to investigate the current conflict and figure out sustainable means to transform the conflict and build peace in …

Security Cooperation Poorly Defined, Nathan L. Fenell

Master's Theses

Security cooperation is a vital component to the national security of the United States. Despite this fact, insufficient military or academic attention has been applied to the subject. The academic and professional void created by this inattention has led academic, journalistic, and military professionals to misuse the term security cooperation, and stray from its doctrinal description as defined by the Department of Defense Dictionary and Associated Military Terms. The academic rigor required to properly express the concept of security cooperation as a peace-time strategy has been absent from both the Department of Defense, and the Department of State, and …

Impact Of Collateral Enlargement On Smooth Muscle Phenotype, Alexander Jerome Bynum

Master's Theses

Peripheral Artery Disease is a very serious disease characterized by an arterial occlusion due to atherosclerotic plaques. In response to an arterial occlusion, arteriogenesis occurs, causing smooth muscle cells to transition from a contractile to synthetic state. Also following an arterial occlusion, functional impairment was seen in the collateral circuit. An immunofluorescence protocol was developed in order to assess the impact of collateral enlargement (arteriogenesis) on smooth muscle phenotype at various time points. Smooth muscle α-actin was used to mark all smooth muscle cells, Ki-67 was used to label proliferating smooth muscle cells, and a fluorescent nuclear stain was used …

The Use Of Computed Tomography To Measure Biogenic Structures In Recently Hypoxic And Normoxic Sediments On The Louisiana Continental Shelf, Valerie Ann Hartman

Master's Theses

Over the past 60 years, seasonal hypoxia in the northern Gulf of Mexico has occurred with increased severity and over a greater area. To determine if biogenic structures in the northern Gulf of Mexico vary in response to hypoxic stress, the seafloor on the continental shelf of Louisiana was analyzed during the spring and fall of 2009 at four provinces of similar sediment type that differ in recent history of bottom water oxygen concentration. Subcores were analyzed by computed tomography (CT) to determine the number, diameter, length, volume, surface area, and depth of biogenic burrow structures in sediments where biogenic …

Jackson, Mississippi, Contested: The Allied Struggle For Civil Rights And Human Dignity, Matthew David Monroe

Master's Theses

Utilizing monthly reports and correspondence of civil rights organizations, in addition to newspaper coverage, oral histories, and memoirs, this study shows that a grassroots, community-driven movement mobilized in Mississippi’s capital to challenge institutionalized discrimination. Yet, racial identity did not dictate exclusively how White and Black Mississippians responded to the unfolding Civil Rights Movement. Conflicting and shifting motivations shaped the nature, extent, and pace by which Blacks and Whites challenged or protected status quo discrimination. The Jackson Movement began as early as 1955 and sustained protest activity into the 1960s. By the summer of 1965, Jackson’s Black community secured most of …

Chemical, Biological, And Preliminary In Vitro Studies Of Novel Vanadium(Iv) Complexes With Schiff Bases And Thiosemicarbazone Ligands, Nerissa Abigail Lewis

Master's Theses

9-Anthraldehyde-N(4)-methylthiosemicarbazone (MeATSC), potassium (E)-2-(2-hydroxybenzylideneamino)-3-(1H-indol-3-yl)propanoate (K[(Sal-L-tryp)] and 2-(2-hydroxybenzylamino)-3-(1H-indol-3-yl)propanoic acid (the reduced Schiff base) were prepared using known synthetic procedures. Two novel thiosemicarbazone ligands, (E)-N-ethyl-2-(4-hydroxy-3-methoxybenzylidene)hydrazinecarbothioamide (N-Ethhymethohcarbthio) and (E)-N-ethyl-2-(1-(thiazol-2-yl)ethylidene)hydrazinecarbothioamide (acetylethTSC), were also prepared. All ligands were characterized by FT IR and electrochemistry. N-Ethhymethohcarbthio were characterized by elemental analysis whereas the reduced Schiff base and K[(Sal-L-tryp)] were characterized by ESI MS. X-ray crystallography was also used to characterize acetylethTSC. The ligands were then reacted with [VO(Sal-L-tryp)(H2O)] (1) (Sal-L-tryp = N-salicylidene-L-tryptophanate) to produce the …

Continuous Analysis Of Photocatalytic Activity In Thin-Films And Coatings, Steven Michael Allee

Master's Theses

Materials that undergo photocatalytic reactions create evolved gases due to ultraviolet light decomposition. Current methods of measuring these gases typically result in destruction of the sample. A test fixture was developed to measure evolved gases in a nondestructive manner through the utilization of a flow-through sensor array system. Preliminary testing indicates responsive measurements down to parts-per-billion sensitivity for some gases and will be compared with mass spectrometry measurements. Further development of this process could lead to the ability to measure photocatalytic reaction gases on a continuous basis without interruption of the process or destruction of materials introduced to the system.

Motivating Factors Influencing Spectator Attendance At Professional Soccer Events In Brazil, Rafael Andreis

Master's Theses

In Brazil, soccer is regarded so highly that Brazilians often refer to their country as o pais do futebol, or the country of football ("Natal Brazil", 2006). Brazil national soccer teams won five of the nineteen World Cup tournaments, a record that is so far unmatched by any other country. Brazil boasts 102 million soccer fans who attend games in the country's 300 soccer stadiums, which, combined, have more than five million seats (Helal et al., 2006; Fifa.com, 2010). However, while the importance of soccer in Brazil is unquestionable, the monetization of professional soccer in Brazil is currently far from …

Developing Dendrifrom Facades Using Flow Nets As A Design Aid, Jonas H. Houston

Master's Theses

This thesis highlights a method of arriving at form that minimizes the need for high end technology and complex mathematical models, yet has structural principles of load flow at the highlighted methods core. Similar to how graphical statics assisted earlier architects and engineers to arrive at form by relating form and forces, this thesis suggests a method of form finding that relates the flow of stresses within solid masses to possible load-bearing façades. Looking to nature, where an abundance of efficient structural solutions can be found, this thesis focuses on a tree-like structural form called the dendriform. In doing so, …

Investigating The Roles Of Ndj1 And Tid1 In Crossover Assurance In Saccharomyces Cerevisiae, Rianna Knowles

Master's Theses

Meiosis is the specialized process of cell division utilized during gametogenesis in all sexually reproducing eukaryotes, which consists of one round of DNA replication followed by two rounds of chromosome segregation and results in four haploid cells. Crossovers between homologous chromosomes promote proper alignment and segregation of chromosomes during meiosis.

Crossover interference is a genetic phenomenon in which crossovers are non-randomly placed along chromosomes. Crossover assurance ensures that every homologous chromosome pair obtains at least one crossover during Prophase I. Crossovers physically connect homologous pairs, allowing spindle fibers to attach and separate homologs properly. However, some organisms have shown an …

Understanding Formation And Transport Of Amorphous Iron Oxyhydroxides In Porous Media Using Microfluidic Flow Cells- A Novel Method To Study Freshwater Iron Cycling, Neha A. Ghaisas

Master's Theses

The ground water and surface water interface (GSI or Hyporheic zone) is a spatially- and temporally-fluctuating biogeochemical transition zone connecting these two distinct hydrological components. The mixing zone is characterized by a near neutral pH, ambient temperature and a sharp oxygen concentration which in turn has deep impact on the iron cycling and thus the fate of contaminants in the water column. We constructed an experimental micromodel that to observe key processes that affect biogeochemical iron cycling in the fresh water interface zones where the oxic surface water mixes with Fe (II) rich underlying ground water. The flow cell was …

Protective Effects Of Milk Phospholipids Against Uv Photodamage In Human Skin Equivalents, Zyra Achay

Master's Theses

The ultraviolet (UV) spectrum has been known to cause damage to skin in varying degrees. UVB radiation (290-320 nm) in particular, has been proven to be highly mutagenic and carcinogenic in many animal experiments compared to either UVA or UVC. The alarming rate of increase in skin cancer incidence has prompted many investigators to pursue other alternatives to sunscreens including changes in lifestyle habits and dietary consumption in order to boost our efforts in tackling this widespread disease. Previous studies employing confocal reflectance, MTT assay and histology suggest that milk phospholipids may possess protective properties against UVB-mediated damage but the …

Stromatolitic Knobs In Storrs Lake, San Salvador, Bahamas: Insights Into Organomineralization, Alexandre J. Fowler

Master's Theses

Storrs Lake, a hypersaline lake on the east coast of San Salvador Island, Bahamas, contains well-developed microbial mats, some of which have developed calcified structures called microbialites. Many of these microbialites are laminated, and therefore classified as stromatolites. This study focuses on small stromatolitic knobs located in the southern portion of Storrs lake, which are still actively forming, to gain insights into the early stages of stromatolite formation. These knobs appear to be forming as the result of in situ micritic precipitation mediated by both photosynthetic and heterotrophic microbial metabolisms. By comparing these small stromatolitic knobs to larger stromatolitic heads …

L’Evolution De La Position Du Philosophe, Intellectuel Engagé A Travers Les Exemples De Voltaire Et Des Nouveaux Philosophes, Thomas Choukroun

Master's Theses

Entre cette nouvelle image du philosophe véhiculée par Voltaire et celles des Nouveaux Philosophes en France dans les années 1970, il n’y a pas grande différence. Le terme « nouvelle philosophie » ou « nouveaux philosophes » est pour la première fois apparu dans le journal Les Nouvelles Littéraires, dirigé par Jean-Marie Borzeix, alors éditeur d’un des piliers de la « Nouvelle Philosophie », Bernard-Henry Lévy.

Pourtant ce sont ces liens que nous allons chercher ici à élaborer, afin d’en présenter à la fois les similitudes et les différences, et de comparer les deux figures du philosophe « engagé …

Effect Of Prostaglandin E2 On Mechanical Stresses Applied By Mc3t3-E1 Osteoblast-Like Cells On A Soft Hydrogel Substrate, Abhijit Deb Roy

Master's Theses

Osteoblasts are sensitive to mechanical stimuli and release Prostaglandin E2 (PGE2) when exposed to a fluid shear stress. The exact mechanism by which these cells sense mechanical stress is not well established. A study of the stresses applied by the osteoblasts, under the influence of PGE2, on a hydrogel provided information regarding intercellular-communication via changes in the substrate surface pattern.

A digital image correlation program was developed using the Levenberg-Marquardt optimization algorithm to analyze images and compare the deformations between pairs of images. Comparisons of images before and after the addition of PE2 to the media showed differences in the …

"Buy Local" Consumer Behavior And Wood Products: A Case Study, Charlotte C. Rand

Master's Theses

Consumers in the United States are increasingly interested in buying locally grown/produced (LG/P) agricultural products (Connor et al. 2009). In comparison, consumer interest in buying local wood products is not evident. In the same way that the LG/P agriculture phenomenon has helped preserve farmland and foster awareness of where food originates, expanding local production of forest products may also create similar benefits for forestland both locally and globally. However, studies examining the “Buy Local” phenomenon and its potential to inform the local production of wood products are not apparent in the literature.

This study examined consumer attitudes and beliefs that …

An Optical Analysis Of The Blowoff Behavior For Bluff Body-Stabilized Flames In Vitiated Flow, Trevor Jensen

Master's Theses

In bluff body-stabilized flames, a variety of physical phenomena contribute to the flame destabilization as lean blowoff is approached. These effects include increased strain on the flame shear layers, decreased attenuation of Bénard-von Kármán vortex shedding, and the presence of thermoacoustic instabilities. Lean, bluff body-stabilized flames were studied in an enclosed rectangular-duct, turbulent combustion rig with a triangular flame holder under vitiated conditions with both symmetric and asymmetric fuel distributions. Air and fuel flows within the rig were characterized using a PIV system and a continuous emissions gas analyzer, respectively.

High-speed videos of these flames undergoing blowoff were taken to …

Experimental And Numerical Investigations Of Tubular-Shaped Direct Methanol Fuel Cells (Dmfcs), Travis R. Ward

Master's Theses

This study focuses on both the numerical and experimental investigations of the novel, passively operated, tubular-shaped, Direct Methanol Fuel Cell (DMFC) as an alternative geometry to the traditional planar-shaped fuel cell. The benefit of the tubular geometry compared to the planar geometry is the higher instantaneous volumetric power density provided by the larger active area, which could be beneficial in applications that require a high instantaneous power while occupying a small volume. First, a two-dimensional, two-phase, non-isothermal model was developed to investigate the steady-state performance and design characteristics of a tubular-shaped, passive DMFC. It was found that a higher ambient …

The Expression Of T-Box (Tbx3) In The Bovine Mammary Gland, Maria L. Procopio Ms.

Master's Theses

Development of the bovine mammary gland is a complex process that is regulated by several hormones, growth factors and transcription factors including but not limited to growth hormone (GH), insulin-like growth factor (IGF)-I and T-box (Tbx)2 and 3. Tbx2 and Tbx3 are transcription factors required for mammary gland development in humans and known to regulate cell cycle. In addition, there is recent evidence that GH increases expression of Tbx3 in osteoblasts independent of IGF-I. Based on these findings, we hypothesized GH and IGF-I will increase Tbx2 and Tbx3 expression in bovine mammary epithelial cells (MEC), the cell responsible for milk …

In Vivo Measurement Of Color Relationships Between The Maxillary Central Incisor And Canine As A Function Of Age, Marie E. Falcone

Master's Theses

Abstract

Introduction

It has long been taught that the basic shade (hue) of the patient can be taken from the canine (i.e. that tooth thought to have the highest chroma of a particular hue) and then that hue can be applied to other anterior teeth but at a lower chroma. However, this concept does not appear to derive from published measurements or observations. This study documented the color relationship between in vivo maxillary central incisors and canines to examine: (1) whether they share the same hue, but have different chromas (as commonly taught); and, (2) whether color differences (∆E values) …

Electrochemical Synthesis Of Single Crystal Metal Nanowires, Nan Li

Master's Theses

Electrodeposition is an efficient and economical approach for template synthesis of one-dimensional (1D) nanostructured materials. Based on the porous membranes as templates during electrodeposition, metallic nanowires, nanorods, and nanotubes can overcome the geometrical restrictions to be inserted into the nanometric recesses with both diameter and length well controlled by tuning the size and thickness of the templates.

In this work, the morphology, growth rate and texture of copper nanowires prepared with templates were investigated by the controlled parameters in various experiments. Cu nanowire arrays with preferential orientations can be successfully synthesized into the Anodic Aluminum Oxide (AAO) templates with optimized …

Characterizing Nerve Fiber Activation By Varying Fiber Diameter And Depth Within A Conductive Medium: A Finite Element Approach, Nathan Daniel Soto

Master's Theses

In some instances neuropathies can be diagnosed through a conduction velocity test. However, not all neuropathies can be classified using this method. Gaining an understanding of how the stimulus level varies for different fiber sizes at different fiber depths within a conductive medium will provide useful information for simulation studies.

Following a two-step approach using COMSOL and MATLAB, a simulation was implemented to investigate the stimulus necessary to activate different sized fibers at different depths. In this two-step approach, COMSOL was used to describe the voltage profile that would be present within a conductive medium after a stimulus was applied. …

Additionally, the research seeks to determine how well ninhydrin develops the paper side of thermal paper using aged prints after exposure to the fuming. Twenty-four random individuals placed a total of thirty sets of fingerprints per person on thermal paper over a 10-day period. Each set of fingerprints consisted of three fingerprints on the thermal side of paper and three fingerprints on the nonthermal side of paper. During the 30 to 40-day time period, however, more specifically …

Beneath The Surface: American Culture And Submarine Warfare In The Twentieth Century, Matthew Robert Mcgrew

Master's Theses

Cultural perceptions guided the American use of submarines during the twentieth century. Feared as an evil weapon during the First World War, guarded as a dirty secret during the Second World War, and heralded as the weapon of democracy during the Cold War, the American submarine story reveals the overwhelming influence of civilian culture over martial practices. The following study examines the roles that powerful political and military elites, newspaper editors and Hollywood executives, and ordinary citizens - equal players in a game larger than themselves - assumed throughout the evolution of submerged warfare from 1914 to 1991. In each …
