Latino/A Lgbtq Migrations, Sarah V. Rodriguez

Master's Theses

Despite Latin America’s lesbian, gay, bisexual, transgender, and queer (LGBTQ) movement’s recent ground-breaking political achievements, wide spread social acceptance of LGBTQ individuals is not evident in every institution, nor in every part of the region. For some, migration to the U.S. is the solution for escaping the strict social constructs of the region. Of the many studies focusing on the LGBTQ individuals, limited research examines the Latino/a segment of the LGBTQ population. The study explores the motivations behind migration as well as the resettlement process of those immigrating to the San Francisco Bay Area from Latin America, focusing on the …

Divergent Discourses: Development Knowledge And Malian Family Planning, Savannah A. Thompson

Master's Theses

I propose that in order to approach corrective recommendations for family planning initiatives an examination of initiative fitness is necessary. Using a Foucauldian approach, this analysis identifies the discursive formations (ideologies) at work in centralized family planning in order to elucidate the female normative model for whom initiative programs are constructed. This norm is contrasted with the lived experiences of Malian women in order to determine if the ideology dictating family planning structures is suitable for the local population. When combined with existing analyses of family planning structures and outcomes, this research helps triangulate family planning in a three-dimensional space, …

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 …

The Limitations Of Girls’ Formal Education In Benin, Emily Elshaw

Master's Theses

This thesis explores the challenges facing Beninese women and girls in their pursuit of formal education, as well as the factors supporting their endeavors. It examines the results of interviews performed with Beninese women from varying socioeconomic backgrounds and addresses the issue of access to formal education from their point of view as well. The study findings point to the multi-faceted nature of this problem, which is rooted in various aspects of underdevelopment including misogynistic abuse, poverty, unemployment and misplaced family priorities as well as misallocation of public funds and poor classroom evaluation. It contributes to an existing body of …

Polymorphic Variation Of The Dgat1 Gene In Cal Poly Holstein And Jersey Breeds And The Correlation Of Milk Fat Content, And Genetic Values, Andrea M. Laubscher

Master's Theses

The selection of dairy cattle is dictated by improvement of yield and composition of milk. Genotyping tests give breeders the opportunity to use previously unavailable information to increase the frequency of beneficial alleles in their herds. A QTL influencing milk yield and composition is located in the centromeric end of chromosome 14. The polymorphism being analyzed is a K232A substitution (lysine to alanine amino acid change) in exon VII of the diacylglycerol acyl transferase 1 (DGAT1) gene. DGAT1 is a key acyltranferase in triglyceride biosynthesis. DGAT1 encodes an enzyme which catalyzes the final step of mammalian triglyceride synthesis from carbohydrates. …

Implementation Of Medicinal Leech Preparation To Investigate The Connection Between The Motor Neuron And Muscle Fiber Via Sharp Electrode Electrophysiology, Chandra Nikole Miller

Master's Theses

There are forty registered organophosphates in the United States and they range from pesticides and insecticides to nerve agents or neurotoxins such as sarin. Organophosphates (OP’s) have been used in chemical warfare for years and tend to lead to death due to an attack on the nervous system. Chemical assays and mass microscopy have been used to assess the concentration of OP’s in the environment, but both methods require the body to metabolize the OP first, which can be detrimental to the victim. It is crucial to come up with a method to investigate and detect these neurotoxins without causing …

Simulated Effects Of Varied Landscape-Scale Fuel Treatments On Carbon Dynamics And Fire Behavior In The Klamath Mountains Of California, Kevin J. Osborne

Master's Theses

I utilized forest growth model (FVS-FFE) and fire simulation software (FlamMap, Randig), integrated through GIS software (ArcMap9.3), to quantify the impacts varied landscape-scale fuel treatments have on short-term onsite carbon loss, long-term onsite carbon storage, burn probability, conditional flame length, and mean fire size. Thirteen fuel treatment scenarios were simulated on a 42,000 hectare landscape in northern California: one untreated, three proposed by the US Forest Service, and nine that were spatially-optimized and developed with the Treatment Optimization Model in FlamMap. The nine scenarios developed in FlamMap varied by treatment intensity (10%, 20%, and 30% of the landscape treated) and …

Digitally Controlled, Modular Electronic Load, Jason L. March

Master's Theses

This project entails the design and development of a digitally controlled, modular electronic load. The proposed load is unique from existing designs because it has the added ability to increase its maximum current level by adding identical modules in parallel. Each module is designed to sink a maximum of 5A at 60V but more modules allow for more current. The cost and simplicity of the design are considered such that it can be reproduced in-house to replace, whenever possible, the resistor box for load testing of any analog circuits but more specifically power electronic circuits.

The design process as well …

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 …

Experimental Investigation Of A 2-D Air Augmented Rocket: Effects Of Nozzle Lip Thickness On Rocket Mixing And Entrainment, Trevor Allen Montre

Master's Theses

Cold-flow tests were performed using a simulated Air Augmented Rocket (AAR) operating as a mixer-ejector in order to investigate the effects of varied primary nozzle lip thickness on mixing and entrainment. The simulated primary rocket ejector was supplied with nitrogen at a maximum chamber stagnation pressure of 1712 psi, and maximum flow rate of 1.67 lb_m/s. Secondary air was entrained from a plenum, producing pressures as low as 6.8 psi and yielding maximum stagnation pressure ratios as high as 160. The primary ejector nozzles each had an area ratio of approximately 20, yielding average primary exit Mach numbers …

Adhesion And Durability Of Coatings On Polypropylene Exterior Sidings, Logan Riekio Stark

Master's Theses

Plastics have become a universal material for use in a myriad of commercial and consumer products. One such product, exterior siding, is the focus of this project. Although siding products were originally made from wood, vinyl siding, which offered superior performance, was introduced in the 1950’s. More recently, polypropylene (PP) siding has been introduced; PP provides a stronger product, which allows for deeper patterns and better edge detailing. PP siding, compared to traditional wood siding, doesn’t warp, crack, or degrade as easily with extended exposure to the elements, and is cheaper to maintain. However, even plastic siding must be coated. …

Freight Truck Traffic Associated With The Port Of Oakland: A Case Study Of Roadway Impacts, James Hinkamp

Master's Theses

The Port of Oakland (“Port”) is the 5th largest container seaport by volume in the U.S. and the largest in Northern California. Maritime shipping activity at the Port exceeds 2 million import and export twenty-foot equivalent unit (TEU) containers annually. Containers may be full or empty, but nonetheless typically require hinterland shipment and intermodal transfer between maritime and land-based freight distribution systems. The freight trucking mode (“drayage”) handles approximately 80% of all TEU throughput at the Port, thus constituting the majority of landside Port traffic. The Port is also situated adjacent to dense urban development thereby exacting certain external impacts. …

A Framework For Developing And Integrating Effective Routing Strategies Within The Emergency Decision Support System, Joseph W. Yu

Master's Theses

In recent years transportation professionals have shown increasing interest in evacuation planning. With the advances in computing technologies it is possible to simulate urban transportation networks with great detail. These details from the traffic simulation model can be used for devising strategies for evacuation and emergency response in case of a disaster.

This thesis describes the modeling, calibration, and validation of the VISSIM traffic simulation model coded for downtown San Jose. The network is then used to test various evacuation scenarios to assess evacuation strategies that would be effective in case of a human-caused disaster.

The network modeled in the …

Digitally-Controlled Deep Brain Stimulation Lead Implant System, Matthew Joseph Phillips

Master's Theses

Deep brain stimulation, the treatment of disorders by applying electrical stimulation to brain tissue, is a relatively new field of medicine with great potential to provide cures for neurological disorders. It utilizes a system very similar to a cardiac pacemaker and lead to electrically stimulate brain tissue. This electrical stimulation is programmed to disrupt or mask aberrant brain signals while not impeding the normal function of the brain. The advances in implantable pulse generators designed for deep brain stimulation have been remarkable, and the applications for deep brain stimulation continue to grow including multiple sclerosis (Berk, et al. 2002), severe …

Assessing Landscape Change In Western Honduras, 1957-2010, Eric Lenhardt Mcgregor

Master's Theses

Human impacts on environmental conditions have long concerned researchers investigating changing forest conditions in the world's tropical regions. This thesis uses repeat photography, satellite imagery, and quantitative spatial statistics to evaluate landscape change in western Honduras between 1957 and 2010, and specifically focuses on changes in tree cover. Results from repeat photography and satellite classification show an increase in tree cover. Spatial statistics indicate that increases in shade coffee production may also be related to much of the observed increases in tree cover. Forest transition theory is used as a framework to help explain the observed changes, such as dooryard …

Quantifying Rates Of Autocompaction In The Pearl River Marsh, Louisiana, Jeremiah Nicholas Prouhet

Master's Theses

Annual rates of shallow autocompaction (< 1 m) were calculated in the upper ~one meter of sediment from six cores of a transect in the Pearl River Marsh (PRM), Louisiana, in order to determine the most significant sedimentary property controlling this process. Compaction-free wedge cores were sub-sampled at one centimeter intervals to collect the following data: age control, using 137Cs and 210Pb, and sedimentary variables, specifically, particulate organic carbon, bulk density, median grain size, porosity, and water content. An upper and an underlying sedimentary unit (named the 137Cs and 210Pb units) were defined between radiometric datum levels, and their sedimentary properties were statistically tested for significant differences using the non-parametric Mann-Whitney test. Rates of autocompaction were calculated from the model of Williams (2003), and both rates of autocompaction and sedimentation were tested for significant differences between the upper and lower sedimentary units.

The upper unit in the six cores generally had lower bulk density, higher water content, higher porosity, and higher particulate organic carbon than the underlying unit, but with some interesting exceptions. Additionally, annual autocompaction and sedimentation rates were greatest in the overlying unit at stations PR02 (0.39 ± 0.05 cm/y) and PR05 (0.42 ± 0.03 cm/y) and greatest in the underlying unit at stations PR02 (0.22 ± 0.08 cm/y) and PR03 (0.18 ± 0.06 cm/y). Based on Spearman correlations, rates of autocompaction were most strongly correlated to and influenced by rates of sedimentation rather …

A Comparison Of The Effects Of A Function-Based Intervention To A Non-Function-Based Intervention To Address Problem Behaviors In Preschoolers, Katherine Marie Bellone

Master's Theses

Problem behaviors occur frequently among preschool children in classrooms, impeding academic development. Past methods employed for development of behavioral interventions include functional assessment and use of evidence-based practices. The current investigation sought to empirically compare the effectiveness of both function-based and non-function-based interventions to increase appropriate engagement and decrease occurrence of problem behaviors. Participants included three preschool children, two attending pre-kindergarten classrooms at an elementary school and one at a Head Start Center. Differential reinforcement of alternative behavior was used as the function-based intervention and was compared to a token economy intervention in an Alternating Treatments Design. Results indicated that …

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 …

State Super-Maximum Security Policies: An Examination Of Admission Characteristics, Classification Reviews, Mental Health Amenities, And Inmate Privileges, Harry Daniel Butler

Master's Theses

Super-maximum security prisons have flourished within a political environment that endorses tougher criminal sanctions. This punitive evolution has created new problems for correctional agencies attempting to control the “worst of the worst” inmates. Federal courts and researchers have examined the detrimental effects supermax isolation has on inmates’ mental health. This analysis examines forty-two state supermax policies to determine how states admit inmates to supermax custody, the classification review process, the management of inmates with mental illnesses, and the availability of privileges for supermax inmates. Drawing on the concept of the McDonaldization of Justice (Ritzer, 1993), particular attention is given to …

The Effects Of Check In/Check Out On Levels Of Problem Behavior And Academic Engagement In Elementary School Students, Leila Mullooly Miller

Master's Theses

Previous studies have largely evaluated the effects of check in/ check out (CICO) using office discipline referrals (ODRs). However, ODRs are not always reliable measures of student behavior, and direct observation is known to be an accurate tool for behavioral measurement. Due to this, the current study used direct observations to evaluate the effects of CICO on levels of problem behavior and academic engagement for a group of elementary school students. One second, one fourth, and one sixth grade student served as participants. Results indicate CICO is effective in decreasing problem behavior and increasing academic engagement. Data from teacher ratings …

Consequences Of Contact: An Evaluation Of Childhood Health Patterns Using Enamel Hypoplasias Among The Colonial Maya Of Tipu, Amanda R. Harvey

Master's Theses

Located in western Belize, Tipu was occupied from 1541-1704. This Colonial Maya population from a Spanish visita mission church was analyzed to investigate health disturbances associated with European contact. Dental defect called enamel hypoplasias were scored to assess childhood health. Standard methods of scoring (Buikstra and Ubelaker 1994) were employed to assess frequency, severity, and type of episode in the permanent anterior dentition. For analysis, 325 individuals were placed into age groups of subadults (6-17 years), younger adults (18-35 years), and older adults (36-50+ years). The population was also considered for differences by sex and tooth type.

Results showed a …

Shady Grove Site (22qu525) Quitman County, Mississippi: Analysis Of Demographics And Mortuary Practices, Stacy Ann Scott

Master's Theses

The Mississippian Period (A.D. 1000-1500) is distinguished by reliance on stable agriculture, sedentary ranked populations, and production of prestige goods. Sociopolitical structure was based on kinship, wealth, and power, and can be revealed through the local mortuary programs. This thesis explores the mortuary practices observed at an ossuary at Shady Grove (22QU525), a small mounded center in Quitman County dating to the Early Mississippian Period, based on demographics, burial mode, cemetery location, and associated grave goods.

The Burial 43 ossuary, excavated in 2010 contained stacked bundle burials of at least 78 individuals. All age groups and both sexes were present. …

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 …

Family, Feud, And The Conduct Of War In Anglo-Saxon England, Elnathan Barnett

Master's Theses

Anglo-Saxon society was built around the concept of feud, and it is clear from history, law, and literature that the twin concerns of family and vengeance remained pillars of Anglo-Saxon society and consciousness throughout the period. Given constant warfare and the cultural and social importance of feuding, it would appear logical that warfare was essentially feud writ large, that conflicts pitted one kin group against another and vengeance for the dead was a major, if not the only, reason for making war. However, royal families often fought among themselves, while wars waged to avenge a death are conspicuous by their …

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 …

Phytoplankton Abundance And Species Composition In Relation To Environmental Paramenters In Coastal Mississippi Waters, Luz Karime Molina

Master's Theses

Phytoplankton pigments from Coastal Mississippi waters were measured to determine the spatial and temporal distributions and composition of phytoplankton communities. Concentration of phytoplankton pigments were analyzed using High Performance Liquid Chromatography (HPLC) and the compositional changes in phytoplankton communities were determined with CHEMTAX 1.95. Surface water was collected for two years (September 2007-November 2009) at three sampling sites on a monthly basis. The stations were located at the Bay of St. Louis (station 1), the Mississippi Sound (station 4) and the Mississippi Bight (station 8), following a salinity gradient. A time series of the observations documented the variability of different …

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.

A Study Of The Early American Author Judith Sargent Murray, Her Role In Early American Print Culture And Her Misappropriation By Twentieth-Century Feminism, Robert Allen Fowler

Master's Theses

In 1798, Judith Sargent Murray published a three-volume collection of one hundred miscellaneous essays on topics ranging from social politesse to women’s education to international politics. Her diligence, forethought and manipulation of pseudonyms in the print-hungry post-Revolutionary America create a unique place for her in the history of American letters. However, in the twentieth century, modern feminism has attempted to claim Murray as one of their own, choosing between one and four examples of her work as proof of her forward-looking philosophy, while ignoring significant pieces of those same works as well as much of her oeuvre as a whole …

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 …

Influence Of Detritus Levels And Organic Pollution On Interspecific Resource Competition, Oviposition Behavior, And Larval Survival Of Two Tire-Inhabiting Mosquito Species (Diptera: Culicidae), David Wayne Allgood

Master's Theses

Mosquitoes (Diptera: Culicidae) are vectors of disease in the adult stage, but understanding the factors affecting distributions of the immature stages is important to the understanding and control of adult populations. Discarded automobile tires comprise important larval mosquito habitats. The Asian tiger mosquito (Aedes albopictus) and the southern house mosquito (Culex quinquefasciatus) are two medically important species commonly found in tires, but factors affecting their larval distributions in tires have not been studied, nor have their interspecific interactions. I investigated the effects of chemicals associated with organic pollution on oviposition preferences and larval survival of both …
