Dislocation And Adjustment Of International Student-Athletes, Thiago Brito Lopes

Master's Theses

One reason that attracts international student-athletes to American universities could be the interest in earning high quality education with the possibility of playing high performance sports. However, when compared to other international students, differences are seen: Other foreign students who look for a degree in the US desire not only an international education, but also potentially staying in the country. The University of San Francisco, where a cosmopolitan city meets education, fits it best. At USF, 82 countries are represented, reaching a number of 1708 students. Approximately ¼ of the whole student population is international. The ratio with student-athletes is …

Power, Subjectivity, And Life In Spain: A Continuation Of Elite Power, Matthew Mason

Master's Theses

On December 20, Spain will hold national elections to determine the new prime minister and national and local parliaments. These elections will be another crossroads in the long history of Spain. The elections come about in a political and social atmosphere of ‘change’ and ‘regeneration,’ marked by the rise of two new political parties, Podemos and Ciudanos. These parties are the new forces in the political scene in Spain. This atmosphere of change is the result of the 2008 economic crisis. The economic crisis of 2008 was not only an economic crisis in Spain, but it provoked a political and …

The Multidimensionality Of Schoolgirl Dropouts In Rural Bangladesh, Tiffany Yancey

Master's Theses

This thesis outlines the underlying causes for girl dropouts in the secondary school system of rural Bangladesh and assesses the barriers that affect adolescent girls and their families. The complex dynamics of the historical context within the patriarchal-dominant structure of society creates a system that hinders girls’ education and forces them into marriage at an early age. Poverty and lack of parental involvement in schools, as well as societal traditions and lack of government infrastructure play an enormous role and are the main structural factors that are linked to schoolgirl dropouts in this study. This thesis also analyzes previous education …

Evolution Of A Nation After A Dictatorship: How Law, Politics And Society Of The 1973 Dictatorship In Uruguay And Of The Subsequent Return Of Democracy In 1985, Potentially Helped Evolve The Nation Of Today., Jonathan A. Fein Proaño

Master's Theses

In 1973, Uruguay’s president authored a coup d’état with the military and changed the history and fabric of Uruguay. Once democracy returned to Uruguay in 1985, it was a chance to see if an evolution of the law, politics and society would occur. This thesis aims to analyze and understand the patterns of change and de-evolution or evolution that happened during the dictatorship and then over the last 30 years. I break down the process of changes that happened legally and politically, how the dictatorship and its leaders used law to destroy rule of law, and how society changed.

Predictors Of Improvement In Risk Reduction Skills Among Hiv Infected Drug Users, Rashmi Dahal

Master's Theses

Background and Objective: Unsafe needle use and unprotected sex are behaviors that have been associated with HIV transmission. Evidence-based behavioral intervention approaches are widely available for preventing HIV transmission, but neurocognitive impairment (NCI) may impede many intervention participants’ capacity to fully benefit from such interventions, leaving them vulnerable to HIV transmission risk. This study examines the impact of NCI on specific intervention outcomes expected to be enhanced through intervention participation.

Methods: Participants were 74 HIV+ opioid-dependent persons participating in methadone maintenance drug treatment and who reported drug- or sex- related HIV risk behavior. Using regression analyses, NCI, HIV knowledge (information), …

Europe’S Refugee Crisis: Assessing The Factors Preventing A Coordinated Eu Response, Ali Albassam

Master's Theses

In order to escape increasing political violence in the Middle East and Africa, many refugees are fleeing by sea to seek asylum in Europe. As a result, Europe has witnessed the highest influx of refugees since World War Two. European Union member states have scrambled for a solution, seemingly unable to form a collective response. The reemergence of nationalism amid the arrival of thousands of refugees not only clouds Europe’s moral compass, but also weakens the EU and its founding principles. In an effort to contribute to the protection of refugees and the EU and its values, this thesis aims …

Effect Of Electrical Stimulation On Muscle Recruitment As It Relates To Maximal Voluntary Contraction, Kelly Stratton

Master's Theses

Regeneration of complex muscle tissue, particularly at the interface between distinct tissue types such as muscle and tendon, remains an intricate and challenging issue. One approach recommended for regeneration is electrical stimulation (ES), which involves delivering an electrical pulse into the body to induce muscle contraction. Despite its well-documented effectiveness in both clinical rehabilitation and tissue engineering, little is known in terms of monitoring direct muscle response to stimulation. The recruitment mechanism for muscular contraction with stimulation is unclear, and to understand the muscle capabilities, it is necessary to filter out the electrical stimulation pulses from electromyographic (EMG) muscle activity, …

Gender, Othering, And Loki 2015, Amanda Munson

Master's Theses

With many enigmatic characters and engaging stories, Norse literature and mythology have had a formative impact on English literature from the early Middle Ages in poetry like the Edda and many Icelandic sagas. A lot of scholarship has been done on Nordic myth and literature, including character studies on many figures, especially Odin and Thor. However, it is difficult to find studies of the figures who make up the "other" in Nordic tales, such as the trickster Loki. While Loki plays a significant role in many tales, his position as the "other" in general Norse mythology and folklore is perhaps …

Muslim Brothers Or Overstaying Guests? The Reception Of Syrian Refugees In Southeastern Turkey, Irem Karaçizmeli

Master's Theses

This thesis contextualizes the Syrian refugee issue in Turkey with an analysis of history and political discourse, and data drawn from a fieldwork conducted in Şanlıurfa, Turkey in 2015. The Islamist ruling party has staged a warm welcome for Syrian refugees. Their refugee regime, however, has remained weak in regards to law and policy. Retaining the geographical limitation stipulated in the 1951 United Nations Convention Relating to the Status of Refugees, Turks have attempted to locate the larger issue of hosting refugees into cultural notions of ‘guesthood’ rather than a developed refugee rights framework. The fieldwork discovers the lack of …

The Effects Of Transcutaneous Electrical Neurostimulation On Analgesia And Peripheral Perfusion, Leah I. Schafer

Master's Theses

Peripheral arterial occlusive disease (PAOD) affects 8 to 12 million Americans over the age of 50. As the disease progresses, arterial occlusions arising from atherosclerotic lesions inhibit normal metabolic vasodilation in the peripheries, resulting in limb ischemia and claudication. Pharmacological and surgical treatments currently used to treat both the hemodynamic and pain symptoms associated with PAOD can involve adverse and potentially life-threatening side effects. Thus, there is a need for additional innovative therapies for PAOD.

Neurostimulation has a known analgesic effect on both acute and chronic pain. Although the exact mechanisms remain under investigation, local vascular tone may be modulated …

A Statistical Model For The Prediction Of Dissolved Oxygen Dynamics And The Potential For Hypoxia In The Mississippi Sound And Bight, Andreas Moshogianis

Master's Theses

Hypoxia events occur when dissolved oxygen concentrations fall below the minimum threshold (dissolved oxygen concentrations < 2 mg O₂ L^-1) necessary to avoid respiratory distress among aquatic organisms. In the Mississippi Sound and Bight, hypoxia is most prevalent from late-spring through late summer. Since hypoxia events can have dramatic effects on coastal fisheries, the spatial and temporal magnitude of hypoxia presents a clear threat to the productive fisheries in the northern Gulf of Mexico. Long-term hydrographic data were collected from eight sampling stations on a monthly basis from January 2009 to December 2011 along a cross-shelf transect from the mouth of …

Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, Megan S. Broadway

Master's Theses

The study of canine cognition can be useful in understanding the ontology and selective pressures that affect the development of cognitive abilities. Dogs have undergone intensive artificial selection yielding distinctive breeds which differ both phenotypically and behaviorally. Breed based cognitive differences have not been found but some studies suggest there may be differences in broader categories such as working disposition and sex. The influence of size on canine cognition has not been thoroughly addressed despite the fact that large dogs are often perceived to be ‘smarter’ than small dogs. This preconception has only recently been addressed and supported in one …

Gut Microbiota Of Migratory Passerines At Stopover, William Bagley Lewis

Master's Theses

Although the gut microbiota provides many beneficial functions to animal hosts, relatively little is known about the gut microbiota of passerines. It is likely that gut microbes are especially important during the migratory phase; however gut atrophy experienced during prolonged migratory flight may cause disruptions of the stable microbiota. Fecal samples were collected from several species of passerine after crossing the Gulf of Mexico during spring migration and before crossing during fall, and microbiota communities were analyzed using next-generation sequencing. Despite showing large inter-individual variation, a core microbiota composed largely of Firmicutes and Proteobacteria was identified in all birds. Microbiota …

Bioarchaeological Analysis Of Oak View Landing (40dr1): An Archaic Population In The Kentucky Lake Reservior, Katy D. Grant-Mclemore

Master's Theses

The biocultural examination of the Archaic population recovered at Oak View Landing (40DR1) investigates the lifeways and adaptations of prehistoric people as they reflect sociopolitical and subsistence strategies.

A comprehensive bioarchaeological analysis was conducted on the adult individuals (18 males, 16 females, 16 of indeterminate sex) excavated from a multiple occupation site located along the Tennessee River in Decatur County, Tennessee. Skeletal indicators used to understand biocultural phenomena were assessed macroscopically on cranial and postcranial elements. Furthermore, mortuary data, for adults and subadults, were used to determine any patterns of preferential treatment at death.

Results from this study indicate that …

Development And Validation Of A Survey Of Knowledge Of Autism Spectrum Disorder, Laura Katherine Hansen

Master's Theses

As autism spectrum disorder (ASD) is more commonly diagnosed, having knowledge of the disorder becomes increasingly important for educators, parents, and the general public. Previous research regarding knowledge of ASD, focused mainly on knowledge possessed by those in the educational field, has found that individuals may perceive themselves as possessing average knowledge regarding ASD but have low actual knowledge (as defined by the researchers) regarding specific aspects of the disorder (Williams et al., 2011). Studies support the notion that there is a general lack of knowledge of different aspects of ASD among teachers; however, there has been little research regarding …

An Integrated Drought Index (Idi) Incorporating Physical And Social Aspects, Rebecca L. Lanier

Master's Theses

The purpose of this research was to determine significant bio-physical (physical and environmental) and social variables that can be integrated into a drought index to predict areas susceptible to drought. Severe drought events are capable of causing millions of dollars in damage. The 1988 drought caused the United States approximately $40 billion in damage. Drought forecasting, modeling, and detection have, therefore, become imperative to understand the social, economic and environmental impacts of droughts, and also to explore how these impacts play a role in the occurrence of a drought. A number of drought indices widely used in the U.S. rely …

Paleopathology At The Shady Grove Site (22qu525): A Study Of Health In The Upper Yazoo Basin During The Middle Mississippian Period, Christopher Brady Davis

Master's Theses

The Mississippian Period (AD 1000-1539) is characterized by increasingly sedentary populations, mound building, ranked societies, and intensified agriculture. As agriculture spread throughout the Eastern Woodlands, it led to widespread health consequences, including poor nutrition and increased levels of infection. Also, environmental shifts during the Mississippian Period (AD 1000-1539) caused drier conditions, potentially leading to crop failures further exacerbating nutritional problems.

This thesis focuses on the health of the Shady Grove site in the Upper Yazoo Basin, a Middle to Late Mississippian medium sized mound center where an ossuary containing up to 100 individuals was excavated in 2010. Focusing only on …

Maternal Effects And Offspring Behavior: Potential Contributors To The Lack Of Recruitment In Mississippi Gopher Tortoises (Gopherus Polyphemus), Aaron L. Holbrook

Master's Theses

Federally threatened in Mississippi, gopher tortoise (Gopherus polyphemus) populations within the state have strongly variable recruitment and are generally in decline. Hatching success is significantly lower in Mississippi than in any other part of the species’ range , and most hatchlings die within the first year. There are few refuges where survival and hatching success is high. Here I compare two populations that differ in recruitment and offspring survival for differences in corticosterone. Corticosterone is a hormone that influences both energy availability and is released in elevated levels during stressful events, like living in poor quality habitat. Prolonged corticosterone elevation …

Feeding The South: An Assessment Of Food Availability In Rural Mississippi, Nicole Baiza Lawrence

Master's Theses

The overall goal of this project is to investigate Mississippi’s rural food environment by assessing the food resources available to rural Mississippians. The primary objectives were to identify sample locations in each of the four cultural regions of Mississippi and determine the food resources available to residents of those counties. The intellectual merit of this research lies in its in-depth exploration of food accessibility in rural areas. Though there is a wealth of literature on the topics of urban food access and food deserts, very little research has been done in rural areas. Most studies focus on urban environments which …

Master's Theses

This thesis ascertains the sequence of burials using fluoride ion electrode analysis at the colonial cemetery at Tipu, Belize in order to explore demographic and other cultural effects associated with European contact. The cemetery at Tipu in west central Belize, dating from within the first century of Spanish contact, has provided one of the largest and best preserved Maya skeletal series, with over 500 burials recovered. While this series has undergone vast amounts of analysis, there has yet been an analysis conducted to view how patterns changed over time. This is of interest given the rapid culture change associated with …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry

Master's Theses

This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …

Recreation Ecology Of Colorado Fourteeners: An Assessment Of Trail Usage And Impacts, James C. Ewing

Master's Theses

The popularity of climbing Colorado’s 14,000 ft. peaks, or “Fourteeners”, has risen dramatically in recent years, raising important sustainability and management questions. Moreover, groups managing the peaks operate with major capital constraints so their efforts need to be informed, prioritized, and efficient. This paper gauges the dynamics of trail usage, explanatory variables, and recreational impacts across all 58 Fourteeners, and details evaluation adjustments that minimize error and produce results in-step with the resource management framework. Relative to a baseline study completed in 2005, substantial changes occurred in trail usage and impact dynamics. The greatest changes were concentrated on peaks previously …

Child Routines And Self-Regulation As Mediators Of Parenting Practices And Externalizing Problems In Preschoolers, Lovina R. Bater

Master's Theses

Studies clearly indicate that parenting practices relate to child externalizing behaviors, although the mechanisms underlying this relation are less well understood. Researchers suggest that daily routines are one way through which parenting practices relate to externalizing behaviors, allowing children to regulate their thoughts, emotions, and behaviors accordingly, potentially promoting development of appropriate self-regulatory behaviors. Self-regulation is also a possible route through which child routines inversely relate to externalizing behaviors. These relationships have been tested in school-age and older children, yet self-regulatory abilities are known to develop during the preschool period. This study examined child routines and self-regulation as serial mediators …

Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz

Master's Theses

Estimating nutrient and energy requirements of exotic animals is a necessary component of nutrition management in zoos and other wildlife facilities. In the absence of species-specific data, domestic animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and rhinoceros, rely on microbial fermentation in the cecum and colon to utilize dietary structural carbohydrates. The study objective was to measure the digestible energy of two (LOW, HIGH) complete pelleted diets by the horse as a model for nondomestic hindgut fermenters. Seven, individually housed, adult Quarter Horse (Equus caballus) geldings were assigned to one of two diets as 100% …
