Education In Post-Conflict Colombia, Juliana Cabrera Pena

Master's Theses

After 52 years of civil war, Colombia now enters a period of precarious peace. The Colombian government and the largest guerrilla group, the FARC, signed a monumental peace agreement which ushered a period of change in a country which has yet to have sustained peace. Utilizing the power of civil society and social services, the Colombian government has the authority to maintain peace. Education, with its stabilizing power, has the capability of cultivating a society of peace. Thus, this thesis explores the level of value and importance the Colombian government is placing on the expansion of quality education to …

Detection, Activity Measurement And Phylogeny Of Ureolytic Bacteria Isolated From Elasmobranch Tissue, Yimu Yang

Master's Theses

Free-ranging marine elasmobranch tissue-associated micro-organisms were cultured from free-ranging Atlantic stingray (Dasyatis sabina) and Atlantic sharpnose sharks (Rhizoprionodon terraenovae). 16S rRNA gene phylogeny indicated bacteria community structure in both elasmobranchs were under phylum Proteobacteria, Firmicutes and Actinobacteria. By conducting split-plot ANOVA, we found the microbial richness is significantly different (P=0.0814) between two superorders of elasmobranch, which may largely due to their preferred habitats and feeding habits. Urease presentence and activity was detected in phylogenetically diverse bacterial strains. Species with high urea-hydrolyzing ability, such as Micrococcus luteus (shark blood isolate: 46.84 mU/mg protein; stingray blood isolate: 24.36 …

Why Sing So Many Songs? Testing The Function Of Song Type Repertoires In Rock Wrens Using Playback Experiments And Behavioral Observations, Stephanie Marie Gobert Pitt

Master's Theses

Bird song has been studied extensively as a model of complex animal communication systems because of how various and flexible it is in certain species. Numerous researchers have investigated the evolutionary pressures leading to the elaboration of songs available in a bird’s repertoire and this topic is most often evaluated in light of sexual selection. Intersexual selection mechanisms such as female choice are often presumed to be very important in the elaboration of song, however literature reviews on the topic find no strong correlation between female preference for larger song repertoires and the presence of the characteristic in males across …

Mobilizing Social Capital: A Qualitative And Network Analysis Of Human Service Organizations, Ethan Christian Adams

Master's Theses

Poverty and homelessness is a social problem that impacts all communities in the U.S. and globally. Social programs that address these issues often focus on mobilizing resources to provide opportunities to increase the social position of their clients and meet their basic needs. Sociological research into this problem, however, has emphasized the influence of social connections in the experiences of individuals in poverty. Social capital is the conceptual representation of actual or potential resources obtained through social network connections. Existing literature regarding social capital has demonstrated that social connections are a critical aspect of human social experience and the ability …

Improving Swarm Performance By Applying Machine Learning To A New Dynamic Survey, John Taylor Jackson

Master's Theses

A company, Unanimous AI, has created a software platform that allows individuals to come together as a group or a human swarm to make decisions. These human swarms amplify the decision-making capabilities of both the individuals and the group. One way Unanimous AI increases the swarm’s collective decision-making capabilities is by limiting the swarm to more informed individuals on the given topic. The previous way Unanimous AI selected users to enter the swarm was improved upon by a new methodology that is detailed in this study. This new methodology implements a new type of survey that collects data that is …

Protection Against Ungrounded Single Phase Open Circuit Faults In 3-Phase Distribution Transformers, Higinio Ariel Montoya

Master's Theses

This thesis explores the impacts and behavior of 3-phase distribution transformers when subject to ungrounded single phase open circuit faults. A simple 3-phase system is modeled using MATLAB Simulink and operation under fault conditions are simulated and studied. Simulation results are confirmed via lab experimentation. Finally, a robust detection and protection method using neutral current injection (as proposed in industry literature) is built and demonstrated.

Electric utility operating experience has demonstrated that all too often, loads on 3-phase distribution transformers are not adequately protected against an ungrounded single phase open circuit fault (commonly called “single phasing”). This type of fault …

Knee Angles And Axes Crosstalk Correction In Gait, Cycling, And Elliptical Training Exercises, Jordan M. Skaro

Master's Theses

When conducting motion analysis using 3-dimensional motion capture technology, errors in marker placement on the knee results in a widely observed phenomenon known as “crosstalk” [1-18] in calculated knee joint angles (i.e., flexion-extension (FE), adduction-abduction (AA), internal-external rotation (IE)). Principal Component Analysis (PCA) has recently been proposed as a post hoc method to reduce crosstalk errors and operates by minimizing the correlation between the knee angles [1, 2]. However, recent studies that have used PCA have neither considered exercises, such as cycling (C) and elliptical training (E), other than gait (G) nor estimated the corrected knee axes following PCA correction. …

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly looked …

The Moderating Role Of Pbs In The Relationship Between Positive Expectancies And Alcohol-Related Negative Consequences, Kray Scully

Master's Theses

Hazardous drinking college students have become an increasingly focused upon group within alcohol research, especially considering the extent of negative consequences they experience. Recently, increased positive expectancies has been identified as an influential contributor to increased hazardous drinking and alcohol-related negative consequences. However, more comprehensive evaluation of the domains of positive expectancies (e.g., sociability, tension reduction, sexual enhancement, liquid courage) is warranted to ascertain which types are more salient in predicting hazardous drinking and alcohol-related negative consequences. Further, research has yet to explore how protective behavioral strategies (PBS) affect the strength of the associations between specific positive expectancies and alcohol-related …

The Role And Contribution Of Saprotrophic Fungi During Standing Litter Decomposition Of Two Perennial Grass Species, Schizachyrium Scoparium And Schizachyrium Tenerum, Matthew Lodato

Master's Theses

In terrestrial ecosystems, most of the plant biomass produced enters the detrital pool, where microbial decomposers colonize, enzymatically degrade, and assimilate plant litter carbon and nutrients in amounts sufficient to bring about the decomposition of plant litter. Here, I estimated the biomass and production of fungi and microbial respiration associated with decaying Schizachyrium scoparium and Schizachyrium tenerum leaf litter, and constructed a partial organic matter budget estimating C flow into and through fungal decomposers. Significant losses in S. scoparium (57%) and S. tenerum (68%) leaf mass was observed during litter decomposition along with concomitant increases in fungal biomass, which reached …

The boundary between these units correspond to a transgressive-regressive sequence boundary, which marks the beginning of a rise in sea …

Automatic Construction Of Scalable Time-Stepping Methods For Stiff Pdes, Vivian Ashley Montiforte

Master's Theses

Krylov Subspace Spectral (KSS) Methods have been demonstrated to be highly scalable time-stepping methods for stiff nonlinear PDEs. However, ensuring this scalability requires analytic computation of frequency-dependent quadrature nodes from the coefficients of the spatial differential operator. This thesis describes how this process can be automated for various classes of differential operators to facilitate public-domain software implementation.

From Dago To White: The Story Of Sicilian Ethnic Evolution In New Orleans Amidst The Yellow Fever Epidemic Of 1905, H. Denise Lopresto Saucier

Master's Theses

The story of the Sicilian immigrants’ experiences in Louisiana is a tale of racial and ethnic evolution in the face of physical threats. With the end of the Civil War, many emancipated slaves migrated to other parts of the country, which left Louisiana planters in need of laborers. Planters turned to European labor to fill that need, bringing thousands of Sicilian peasants to work on their plantations. Extreme poverty and oppression made the opportunity to emigrate highly attractive, but Sicilians found problems in Louisiana as well. In addition to low wages, crowded living conditions, discrimination, and violence, the immigrants faced …

Linkages Between Marsh Fragmentation, Prey Availability, And Blue Crab (Callinectes Sapidus) Abundance And Mortality, Lennah Shakeri

Master's Theses

Coastal marshes are important nursery habitats for many commercially important invertebrate species, yet these marshes are being lost worldwide at an unprecedented rate due to subsidence, erosion, climate change, and human activity. As marsh is lost, it creates the opportunity for submerged aquatic vegetation (SAV) colonization and establishment in newly created open water areas. Blue crabs, Callinectes sapidus, use both marsh edge and SAV habitat during the juvenile stages and support one of the largest fisheries in the Gulf of Mexico, worth over $70 million in 2015. This thesis studied the linkages between habitat type, SAV cover, benthic prey …

Natural Disasters And Attachment Quality: The Mediating Role Of Coping, Alexandra Teller

Master's Theses

Research shows a strong relationship between children’s exposure to a natural disaster, parental distress, and development of mental health problems. It is theorized that trauma-related parental distress is associated with maladaptive parenting behaviors, which negatively impact the psychological development of children. The long-term impact of trauma exposure from a natural disaster on parent-child relationship quality and mental health outcomes for emerging adults has only been minimally investigated. The use of adaptive coping strategies has been found to be helpful for preventing mental health problems, while maladaptive coping has been associated with the development of psychopathology. The present study examined the …

Identifying Overwash Deposits In Arid Environments: Towards A Millennial-Scale Record Of Cyclones And Makran Trench Tsunamis From Sur Lagoon, Oman, Anne Griffis

Master's Theses

Coastlines along the Arabian Sea are susceptible to marine inundation from Makran Subduction Zone (MSZ) earthquakes and tropical cyclones. Sediments deposited by these forms of inundation can expand the decadal instrumental record of events to include millennial timescales in regions without rich historical records (i.e., Oman). On November 28, 1945 a 8.1 M_w MSZ earthquake generated a tsunami that inundated coastlines of the Arabian sea with wave heights as high as 13m. The stratigraphic, sedimentological, foraminiferal, and geochemical signatures of deposit were examined from a small (12 km²), microtidal lagoon in Sur, Oman. The 1945 tsunami deposit …

Life-History Characteristics And Fishery Dynamics Of Red Drum (Sciaenops Ocellatus), In The North-Central Gulf Of Mexico, Corbin Bennetts

Master's Theses

Red Drum (Sciaenops ocellatus) are highly targeted recreationally in the Gulf of Mexico, and support a small commercial fishery in Mississippi. Despite their popularity, the stock is assessed using data limited approaches that necessitate accurate life history information. I estimated the year-specific and year-aggregated escapement rates for the Mississippi stock (years 2004 to 2015), which were sensitive to mortality estimation methods; year-aggregated estimates were 6.9 to 28.2 % depending on the method, but temporal patterns were consistent. I then addressed concerns with previously estimated life-history characteristics by describing the sex-specific growth and reproductive dynamics. The three-parameter von Bertalanffy …

Comparing The Relative Effectiveness Of Function-Based Antecedent And Reinforcement Interventions For Increasing Preschoolers’ Appropriate Behavior, Ashley Murphy

Master's Theses

The current study extended current literature regarding using brief functional analysis methodologies to inform function-based intervention for increasing preschool students’ academically engaged behavior. Teachers were prompted through brief functional analysis procedures by the researcher. Brief functional analysis results informed two function-based interventions: an antecedent intervention - pre-session non-contingent reinforcement, and a reinforcement intervention – differential reinforcement of alternative behavior. The two interventions were compared according to effectiveness on increasing preschool students’ academically engaged behavior and social validity ratings from teachers. Results indicated for all three participants the reinforcement intervention was not only more effective, but also received higher social validity …

Muscle tissue samples were collected from October 2014 through September 2015. Stable isotope analysis identified a trophic gradient extending from nearshore to offshore, with …

Interplay Of Dgat1, Pdat1 And Dgat2 Enzymes In Plant Triacylglycerol Assembly, Anushobha Regmi

Master's Theses

Acyl-CoA:diacylglycerol acyltransferase (DGAT) catalyzes the transesterification of fatty acid from acyl-CoA to diacylglycerol (DAG) forming triacylglycerol (TAG, a.k.a oils and fats). Most plants have at least two unrelated DGAT genes, DGAT1 and DGAT2. Plants predominantly express only one during oil synthesis; the reason, however is not clear. A few studies have indicated that each enzyme prefers DAG and acyl-CoA substrates with different fatty acid compositions. Industrially desirable seed oil composition can be obtained through genetic engineering by replacing the endogenous enzyme with one that has different substrate selectivity. In Arabidopsis thaliana, DGAT1 and another unrelated enzyme PDAT1 are essential …

Impact Of Prolonged Sitting On Central Hemodynamics: Role Of Intermittent Pneumatic Compression Therapy, Anna Kayleigh Downey

Master's Theses

Prolonged sitting (3-6 hours) negatively impacts peripheral vascular health. Whether sitting similarly impacts central cardiovascular hemodynamics and vascular stiffness is unknown. Purpose: Determine if prolonged sitting increases central blood pressure, aortic pulse wave reflection and vascular stiffness. Methods: In 10 subjects (Age=22±2 yrs, BMI=28±4kg/m², 3 females), brachial artery pulse wave analysis was performed before (baseline-BL), during, and after 3 hours of sitting. Aortic pulse wave velocity (PWV) was examined before and after sitting using carotid applanation tonometry coupled with oscillometry performed on left upper-thigh. For mechanistic insight, intermittent pneumatic compression (IPC) was applied during sitting (i.e., 3, 120 …
