Magnetic Minerals Of The Lower Poleslide Member Of The Brule Formation, Badlands National Park, Rebecca V. Kipf

Master's Theses

The White River Group in Badlands National Park is significant because it contains abundant mammal fossils. Many of these fossils are unique to the Great Plains and one of the major challenges has been to learn where these fossils fit in the geologic global time scale. Paleomagnetic studies have been instrumental in correlating and dating these faunas. The purpose of this study is to look at the specific magnetic mineralogy for a complete stratigraphic column of the lower Poleslide Member of the Brule Formation at Cedar Pass. This study attempts to determine what minerals provide the paleomagnetic remanence in these …

Effects Of Exercise Training On The Blood Lactate Response To Acute Exercise In Cancer Survivors, Arjun Ramani

Master's Theses

Otto Warburg, a German physiologist, deduced that cancer cells exhibit a remarkably different metabolic profile in comparison to normal healthy cells characterized by increased rates of glycolysis and lactate fermentation, even in the presence of adequate oxygen content. Through the respective gain of function/loss of function of oncogenes and tumor suppressor genes, three major genes emerge as hallmarks of carcinogenic metabolic reconfiguration; HIF-1a, c-Myc oncogenes, and p53 tumor-suppressor genes. A result of their respective gain/loss of function are the upregulation of several glycolytic proteins and subsequent high rates of glucose influx into the tumor microenvironment, as well as lactate production, …

Exploring The Influence Of School-Based Sexuality Education Settings On Lgbtq+ Sexual Identity Development, Lauren Marie Guyer

Master's Theses

Previous research on sexual identity development demonstrates that there are five discernible, non-linear statuses in which individuals may pass through as they develop their sexual identity: compulsory heterosexuality, active exploration, diffusion, deepening and commitment, and synthesis (Dillon, Worthington, and Moradi 2011). Moreover, prior research on school-based sexuality education (SBSE) demonstrates that no matter its formal designation or political perspective, SBSE is exclusionary, inadequate, and habitually reproduces social inequalities (Bay-Cheng 2003; Elia and Eliason 2010b). SBSE programs within the United States are insufficient because they unvaryingly promote a heteronormative discourse and do not address the sexual health needs or experiences of …

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The …

The Road To Recovery: Injured Athlete's Perspectives On Recovery Through Social Support, Brooke Kuhn

Master's Theses

Injured athletes’ perspectives on different aspect of their recovery process were analyzed using concepts such as social support, responsiveness, and self-disclosure based on three different sources: coaches, trainers, and teammates. 39 participants were used for this study. With an age range from 18-44 years old, the participants are both current college and former college athletes. Many of them ranged from the different types of sports played and at different divisional levels. 82.1% of participants were Caucasian, 12.8% were African American, and 5.1% selected other as their ethnicity. The results exemplify, through linear regression, that trainers are the most effective source …

A Comparison Of Social Learning In Domestic Canines, Beatrice Chenkin

Master's Theses

Domestic canines (Canis familiaris) provide a unique insight into the processes by which species can grow to cooperate efficiently with humans. Few studies have compared whether their behavior is more affected by humans or other canines. This study uses a two-action feeder (an apparatus that can be opened in one of two ways) to look into the methods of social learning they use and compares how they learn from humans vs. other canines. Sixty-four dogs from the Humane Society of varying backgrounds, ages, sexes, and reproductive statuses were tested on their ability to open the two-action feeder and the amount …

Posture Affects Affordance Perception Of Reachability In Virtual Reality, Hannah Masoner

Master's Theses

Tasks such as standing and reaching require differing levels of postural stability. Postural equilibrium is necessary to perceive the location of objects (Lee, Pacheco, & Newell, 2018). Visual perception of whether an object is within reach was investigated while standing upright. Participants viewed a 3D virtual reality (VR) environment with a stimulus object (red ball) placed at different egocentric distances. Participants made affordance judgements while in a standard stance condition as well as two separate active balance conditions (yoga tree pose, and toe-to-heel pose). Feedback on accuracy was not provided, and participants were not allowed to attempt to reach. Response …

Are You Happy? Local Economic Development In Northern Thailand, Katherine Sorensen

Master's Theses

Thailand has had a long history of economic development. In recent years, Thailand began to focus on economic development initiatives a local level. The implementation process has been slow, but the introduction of social enterprise programs has proven a promising strategy in local economic development. Successful examples of economic development can be found in Thailand wherein this paper argues through collaboration between government agencies and local communities lies the key to success.

Qualitative techniques including a two months of fieldwork in Thailand, first hand observations, and appreciative inquiry interviews are used to analyze economic development initiatives in the communities of …

Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, Ashleigh Nicole Price

Master's Theses

Hazards research continually examines how specific groups are affected by damaging events and how their unique sociodemographic characteristics contribute to variations in resilience and recovery. Studies have shown that underprivileged communities suffer more adversely and take longer to recover from hazard events. Probationers and parolees are uniquely disadvantaged regarding demographics and economic opportunity, both of which contribute to increased vulnerability and reduced resilience. Numerous legal restrictions and widespread discrimination towards former criminals means offenders are often relegated to underserved, criminogenic neighborhoods. Given such severe social and financial limitations, offenders have little capacity to prepare for or recover from disasters.

The …

Exploring The Moderating Effects Of Aggression On The Relationship Between Negative Urgency And Suicidal Desire, Rachel L. Martin

Master's Theses

Suicide is a health concern with 44,965 deaths in 2016. Typical assessment of risk factors relies on self-report, which can be susceptible to underreporting. As such, non-face valid measures and innovative assessment approaches such as implicit association tests may help identify risk factors by eliminating conscious underreporting. The Interpersonal-Psychological Theory of Suicidal Behavior is an empirically supported theory hypothesizing why individuals die by suicide. The theory comprises three elements: thwarted belongingness, perceived burdensomeness, and capability for suicide. Thwarted belongingness and perceived burdensomeness have been found to be non-face valid measures and less susceptible to conscious underreporting. Objective measures, such as …

Detecting Coastal Marsh Change From Aerial Imagery Using Spectral And Textural Methods: Pascagoula River Estuary, Mississippi, 1955-2014, Margaret Claire Bell Waldron

Master's Theses

As sea level rise accelerates, coastal marsh ecosystems are increasingly vulnerable. Vertical accretion rates must exceed or keep pace with rates of sea level rise to prevent transition to open water or inland migration of marsh vegetation. While some marsh systems along the northern Gulf of Mexico coast have remained stable, others, e.g., the marshes of the Louisiana Gulf Coast, have experienced high rates of conversion to open water. This study examined the historical extent of intertidal marsh at the mouth of the Pascagoula River in Jackson County, Mississippi to determine whether marsh extent changed during the period 1955-2014 and …

Hope For Struggling School Districts, Mary D. Travis

Master's Theses

Education improves the opportunities and life-chance outcomes of our children, and is a key factory in both economic and community development. Although high school graduation rates have shown improvement nationwide in recent years, public education is suffering from increasing inequality between different school districts and within the same school districts. Such inequalities widen academic outcome gaps and can result in entire school districts being branded as academic failures. However, there is also encouraging evidence of struggling schools and school districts moving toward improvement. Innovative leaders who are committed to inclusive and rigorous academics, shared leadership, and an in-depth understanding of …

Zika Message Analysis, Alexandria Phipps

Master's Theses

The following study employs the Extended Parallel Processing Model and Theory of Planned Behavior to understand how to create health messages with the greatest influence on individuals’ behavioral intent to adopt mosquito-borne virus protection behaviors. The study employs a 2 (susceptibility) x 2 (self-efficacy) factorial design, evenly distributing the participants between four messages (N=186). Although the selfefficacy manipulation was ultimately unsuccessful, the findings highlighted the significance of perceived susceptibility on one’s intent to adopt protective behaviors. The results exemplify the importance of the theoretical critical point of the EPPM, where danger control shifts to fear control, and the importance of …

Maize And Bone: An Evaluation And Expansion Of A Proposed Model For The Differential Diagnosis Of Pellagra In Human Remains, Myra G. Miller

Master's Theses

This study attempts to test and expand a previous study to establish a differential diagnosis of pellagra in human remains (Paine & Brenton, 2006a). Seven individuals with documented pellagra and nine individuals randomly selected for comparison from the Hamann-Todd Osteological Collection were evaluated for caries, alveolar bone loss, periostitis, osteoporosis, cribra orbitalia, and porotic hyperostosis. Results indicate that the pellagra sample had lower rates of caries and alveolar bone loss, and higher rates of periostitis of the tibia and fibula in relation to the comparison sample. No osteoporosis, cribra orbitalia, or porotic hyperostosis was found in the pellagra sample. No …

Predicting College Students' Career Interests To Be A Police Investigator Rather Than A Patrol Officer, Alyssa Viator

Master's Theses

In the field of criminal justice, much research has been dedicated to investigating policing in the 21^stcentury. However, there is a lack of research regarding predictions of career preference among college students, more specifically, millennials. This study was designed to fill that gap in the literature by examining interests in police patrol careers. The methodology involved included multiple regression as a way to potentially predict career preference for a police investigator rather than a patrol officer. The results provided promising results for the overall understanding of career preference for millennials. This study also provided crucial discussions for policy …

Mapping Sex Offenders And Treatment Centers In Relation To Social Disorganization, Amber Amin

Master's Theses

Research shows that the clustering of Registered Sex Offenders (RSOs) is connected to social disorganization. Residential patterns disrupt the reintegration of the RSO population. Utilizing data from Queens and the Bronx, NYC, this study examines RSO clustering in the two boroughs and explores the proximity of community resources to RSO addresses that may assist reintegration. Using data from the New York Megan’s Law and census data for Queens and Bronx Counties, maps were created to study the residential patterns of RSOs. The results show clustering of RSOs in areas with variables pertaining to high social disorganization and a lack of …

Macrobenthos Responses To Dam Removal And Habitat Restoration In The West River, Connecticut, Robert W. Sheridan

Master's Theses

Dam removal is being increasingly used nationwide to restore impaired rivers and streams. While dam removals are becoming more prevalent, little is known about whether these efforts create conditions for the enhancement and or establishment of desired biota.

Ongoing monitoring of these projects is an important step in the restoration process to ensure project goals are being met and the restoration has been successful.

This thesis focuses on the Pond Lily Dam removal and restoration which took place in October 2015 along the West River in New Haven Connecticut that removed an aging mill dam with the objective of restoring …

Additive manufacturing has seen sustained growth in both consumer and industrial areas. fused deposition manufacturing (FDM), a specific additive manufacturing technology, has seen increased sales in consumer markets. In order to maintain growth, FDM will be increasingly used for load-bearing applications. However, the mechanical reliability of FDM polymers and composites is not well understood. This can be dangerous to property and safety. Presented in this paper are more than 16 distinct populations comprised of at least 23 unique tensile tests, a total of 506 tensile tests. Weibull statistics were used to quantify variance in physical properties of FDMed materials. It …

Leadership Style As A Moderator Of The Relationships Between Role Stressors And Organizational Commitment, Tanya Chellani

Master's Theses

The purpose of the present study was to examine the moderating effect of leadership style on the relationships between role stressors and organizational commitment. The study hypothesized that negative relationships between role conflict and role ambiguity and both affective and normative commitment would be weaker for employees who perceived their supervisors as relationship-oriented rather than task-oriented. Furthermore, the study explored the direct relationship between role stressors and continuance commitment, along with the moderating effect of leadership style on this relationship. Responses to an online survey from 126 employees were analyzed using hierarchical multiple regression. Results showed that leadership style did …

Green Stormwater Infrastructure Assessments In Santa Clara County, Ca: An In-Situ Analysis Of Select Bioretention Projects, Laura Bates

Master's Theses

Stormwater runoff, defined as rainwater that flows over impervious surfaces, is both an under-harnessed groundwater resource and the leading contributor to water body impairments due to the number of pollutants it can transport. One widely successful strategy to capture and treat stormwater runoff is to implement Green Stormwater Infrastructure (GSI): engineered green spaces to enhance the overall environmental quality of an urban landscape. GSI projects, particularly bioretention systems, capture and treat stormwater runoff through infiltration and plant absorption before it reaches receiving bodies of water. In order to operate efficiently, GSI systems require specific maintenance procedures. The purpose of this …

Avocado Root Rot: Steep, Rocky Terrain And Biodiversity Help Protect Small Farmers In Post-Conflict Colombia, Morgan Frankel

Master's Theses

In recent years, small avocado producers in coastal Colombia returned to their farms after decades of war to discover they must battle the pathogen Phytophthora cinnamomi devastating their trees. While this disease is well-described in the U.S., Australia, and Europe, no previous research has examined environmental correlates of P. cinnamomi in avocado in the diverse tropical agroecosystem of the Colombian Montes de Maria. I used agroecosystem inventory, in-field diagnostics, and disease observations to describe avocado agroecosystem diversity and identify relationships among P. cinnamomi presence, root rot disease, slope, pH, soil compaction, elevation, and distance to the household in remote smallholder …

Photovoltaic Waste Management And Implementing Extended Producer Responsibility In The Solar Industry In California, Lee-Tan Lu

Master's Theses

Electronic waste issues impact humans and the environment, primarily because most industrial designs have not considered the impact of products when they reach their end-of-life (EOL) stage. This study focuses on photovoltaic (PV) modules that are widely installed in California residential properties. While PV modules do not generate waste while operating, they will become waste at the end of their expected lifespan of 25 to 40 years. Thus, it is important to identify PV waste management strategies before the materials in the modules become a discard problem. In California, despite hazardous materials that are used in the production of PV …

The Moderating Effect Of Self-Esteem On The Relationship Between Servant Leadership And Organizational Citizenship Behaviors, Whitney Kanavel

Master's Theses

Previous research has shown that servant leadership is related to organizational citizenship behaviors. However, little attention has been paid to the possible moderators of this relationship. Therefore, the present study proposed that a personality characteristic (self-esteem) will moderate the relationship between servant leadership and organizational citizenship behaviors. It was hypothesized that the relationship between servant leadership and organizational citizenship behaviors would be stronger for employees with low self-esteem than for those with high self-esteem. Results of a self report survey from 204 employed individuals in various industries found that self-esteem moderated the relationship between servant leadership and organizational citizenship behaviors. …

Moderating Effect Of Trait Mindfulness On The Relationship Between Job Demands And Burnout Using The Job Demands-Resources Model, Anne O'Brien

Master's Theses

The Job Demands-Resources (JD-R) model was constructed to explain the antecedents, consequences, and relationships of burnout, and has provided evidence that personal resources moderate and weaken the relationship between job demands and burnout. Although much of the personal resource literature focuses on personality traits like optimism and self-esteem, the moderating effect of trait mindfulness on the relationship between job demands and job burnout has yet to be examined. The study hypothesized that mindfulness moderates the relationship between four job demands (role ambiguity, interpersonal conflict, work-life conflict, and cognitive demands) and three dimensions of burnout, such that those with higher levels …

Effects Of Lisdexamfetamine On Effort-Related And Consummatory Behaviors Supported By Foods With Varying Degrees Of Palatability: Exploration Of A Binge-Like Eating Model, Rose Presby

Master's Theses

Diets high in sugar or fat are associated with multiple health conditions, including binge eating disorder (BED). BED affects approximately 2% of the US adult population, and occurs more frequently in females. It is important to develop animal models of palatable food consumption, food seeking, and voluntary physical activity that may have relevance for BED. The d-amphetamine prodrug lisdexamfetamine (LDX) is used to treat BED. The present experiments studied the effect of LDX on food intake and effort-based choice tasks in female Wistar rats. In experiment one, three groups of rats received different food exposure conditions randomly spread over several …

Understanding Trade-Offs Between Built And Natural Assets In Coastal Management Projects For Inland, Coastal Residents Using Latent Class Modeling Techniques: An Application To The Connecticut Coastline, Julia Dumaine

Master's Theses

Climate change threatens our established communities worldwide through consistently increased average surface temperatures, rising sea levels, and precipitation extremes, and Connecticut is no exception (U.S. Global Change Research Program 2017). As coastal communities in Connecticut increase their focus on mitigating the effects of climate change, they are not always able to incorporate town residents’ preferences and values into their planning; particularly those residents who may not receive a direct benefit from the plan of which they contribute tax dollars towards. Our study attempts to estimate these preferences and values by using a choice experiment survey distributed across the Connecticut coastline …
