Why Do They Do That? Understanding Factors Influencing Visitor Spatial Behavior In Parks And Protected Areas, Abigail M. Sisneros-Kidd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Visitors to parks and protected areas within the United States and worldwide often visit these areas with a particular destination in mind, such as seeing Old Faithful erupt in Yellowstone National Park or standing on the rim of the Grand Canyon in Grand Canyon National Park. These visitor use destinations, and the pathways leading to them, such as trails and roadways, see high levels of use, and as a result, impacts to soil, vegetation, air, water, soundscapes, and night skies that result from this use. The field of recreation ecology studies these impacts to park and protected area resources resulting …

A Parametric Analysis Of Choice Under Risk, David W. Sottile

Masters Theses

Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake …

Estimation Of Zero-Inflated Population Mean: A Bootstrapping Approach, Khyam Paneru, R. Noah Padgett, Hanfeng Chen

Journal of Modern Applied Statistical Methods

A mixture model was adopted from the maximum pseudo-likelihood approach under complex sampling designs to estimate the mean of zero-inflated population. To overcome the complexity and assumptions of asymptotic distribution, the maximum pseudo-likelihood function was used, but a bootstrapping procedure was proposed as an alternative. Bootstrap confidence intervals consistently capture the true means of zero-inflated populations of the simulation studies.

A Room With A View: Local Knowledge And Tourism Entrepreneurship In An Unlikely Indonesian Locale, Kathleen M. Adams, Dirk Sandarupa

Anthropology: Faculty Publications and Other Works

This article highlights the understudied role of local knowledge in contributing to the resilience of small-scale entrepreneurial tourism businesses in touristically-unpredictable times. Drawing on a micro-case study of a South Sulawesi (Indonesia) tourist-oriented restaurant-hotel that has thrived despite tourism’s ebbs and flows of tourism, we suggest that greater attention to the ways in which successful small-scale tourism entrepreneurs draw on local wisdom can help identify additional foundations for building resilience strategies. In spotlighting local knowledge as an under-recognized resource, this article also speaks to recent calls for the decolonization of tourism studies.

Nutrition Transition Of Hadza Foragers: Implications For Juvenile Behavior, Trevor Pollom

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Hadza foragers of Tanzania are undergoing early stages of nutrition transition and an increased level of market integration. Accompanying these shifts is a significant change in diet composition with greater access to maize, wheat, and other domesticated cultigens, even in the most remote bush camps. Despite the rapid rate of nutrition transition, few studies have attempted to quantify the possible effects this transition is having on Hadza diet or foraging behaviors. Here, we attempt to fill this gap in the literature by reporting results of a mixed methods cross-sectional study on juvenile foragers taken from two time points, 2005 …

Toward Understanding Posttraumatic Stress And Depression Among Trauma-Affected Widows In Sri Lanka, Jessica E. Lambert, Alyssa Banford Witting, Spencer James, Lakmal Ponnamperuma, Thulitha Wickrama

Faculty Publications

Objective: In this study, we applied conservation of resources theory (Hobfoll, 1989) to explain high rates of depression and posttraumatic stress symptoms (PTSS) among war- and disaster-affected Tamil widows in the Eastern Province of Sri Lanka. We hypothesized exposure to potentially traumatic events and severity of current contextual problems would influence PTSS and depressive symptoms directly and indirectly through loss of psychological (view of self), environmental (sense of community), and energy (physical health) resources. Method: Trained research assistants interviewed a convenience sample (N = 381) of women, using established measures of the constructs of interest. Data were analyzed using …

Reconstructing Landscape Use Patterns Using Strontium Isotope Ratios, Marian Irene Hamilton

Anthropology ETDs

This dissertation uses modern habitats and fauna to model the variability and predictive power of strontium isotope ratios in identifying dispersal patterns in primates and habitat preference in primate and non-primate fauna. It concludes that there are significant isotopic differences between gallery forest and xeric grassland habitats in the same area and that these differences are reflected in fauna with habitat preferences for one or the other. It also identifies the most reliable methodological approaches for identifying the philopatric and dispersing sex in primate communities. Finally, it applies this methodological recommendation to strontium isotope data from South African hominins, concluding …

The Spatial And Temporal Domains Of Modern Ecology, Lyndon Estes, Paul R. Elsen, Timothy Treuer, Labeeb Ahmed, Kelly Caylor, Jason Chang, Jonathan J. Choi, Erle C. Ellis

Geography

To understand ecological phenomena, it is necessary to observe their behaviour across multiple spatial and temporal scales. Since this need was first highlighted in the 1980s, technology has opened previously inaccessible scales to observation. To help to determine whether there have been corresponding changes in the scales observed by modern ecologists, we analysed the resolution, extent, interval and duration of observations (excluding experiments) in 348 studies that have been published between 2004 and 2014. We found that observational scales were generally narrow, because ecologists still primarily use conventional field techniques. In the spatial domain, most observations had resolutions ≤1 m2 …

Linguistic Political Ecology With The Ngäbe Indigenous People Of Panama, Ginés A. Sánchez Arias

LSU Doctoral Dissertations

Indigenous communities from all corners of the globe live in uncertain times. From the vantage point of their “remote" lands, they undergo some of globalization’s most harmful externalities. Their homes become increasingly harder to maintain as extractive industries, development schemes, clandestine land grabs, and national bureaucracies encroach creating new colonial lands. First by assimilation, and then integration, these processes systematically undermine indigenous culture and autonomy. In place of such destructive coloniality, indigenous societies shelter unique ecological and linguistic knowledge that continues to serve their progress. This research applies lessons learned from studying with Ngäbe communities of western Panama, towards a …

Remote Sensing And Spatial Metrics For Quantifying Seagrass Landscape Changes: A Study On The 2011 Indian River Lagoon Florida Seagrass Die-Off Event, René Dieter Baumstark

USF Tampa Graduate Theses and Dissertations

Florida’s seagrasses are ecologically important marine environments which have suffered major degradation caused by increasing anthropogenic pressures. A 2011 seagrass die-off event caused by an algal bloom in the Florida Indian River Lagoon (IRL) was particularly severe with a majority of seagrass lost in areas such as the Banana River. An understanding of how this coastal marine environment changed is an important step toward better managing resources for conservation. Modern tools and methods provide new opportunities to study these changes at the landscape scale, a scale that informs on the larger more comprehensive state of a system. Classified satellite imagery …

Exploring Places Of Street Drug Dealing In A Downtown Area In Brazil: An Analysis Of The Reliability Of Google Street View In International Criminological Research, Elenice De Souza Oliveira, Ko-Hsin Hsu

Department of Justice Studies Faculty Scholarship and Creative Works

This study assesses the reliability of Google Street View (GSV) in auditing environmental features that help create hotbeds of drug dealing in Belo Horizonte, one of Brazil’s largest cities. Based on concepts of “crime generators” and “crime enablers,” a set of 40 items were selected using arrest data related to drug activities for the period between 2007 and 2011. These items served to develop a GSV data collection instrument used to observe features of 135 street segments that were identified as drug dealing hot spots in downtown Belo Horizonte. The study employs an intra-class correlation (ICC) statistics as a measure …

Parks As Places Of Public Solace: The Perception Of Parks After 9/11, Ryan Hammond

The Pegasus Review: UCF Undergraduate Research Journal

This paper investigates the utilization and public perception of parks in New York City following the 9/11 attacks, using a quantitative content analysis of local newspapers published within a year of the attack, specifically looking for themes indicating how parks were perceived and used. My preliminary findings indicate that parks were frequently used for large gatherings and memorials, that people found solace in the parks themselves, and that communities either formed or strengthened through use of parks following the attacks. In conclusion, the creation and promotion of large common green areas in urban spaces may serve as a means of …

Intensive Archeological Survey Of The Willrae Tract City Of Florence, Williamson County, Texas, Caitlin Gulihur, Beth Valenzuela, Ann M. Scott

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Georgetown Independent School District (GISD) has proposed the Willrae Tract project where school facilities will be constructed south of Florence, Williamson County, Texas. GISD retained Terracon Consultants, Inc. to conduct a systematic, intensive pedestrian survey of the approximate 100-acre project area. Because GISD, a political subdivision of the State of Texas, sponsored the project, the proposed undertaking is subject to compliance with the Antiquities Code of Texas and oversight from the Texas Historical Commission. In addition, the survey meets the standards for compliance under Section 106 of the National Historic Preservation Act of 1966, as amended, should a US Army …

Archeological Survey Of The Port Of Calhoun, Llc. Dock Facility Calhoun County, Texas, Eric Schroeder

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

The Port of Calhoun, LLC. is planning to construct a commercial facility for transporting and storing sand. The facility includes the construction of a number of onshore deadmen for barge mooring, a bulkhead for loading and unloading barges, buildings for sand storage, and an area for the disposal of dredge material. Because the project will involve the placement of fill within the ordinary high water mark of the Victoria Barge Canal, the project will require a permit from the U.S. Army Corps of Engineers, Galveston District (Corps). Since the issuance of this permit is a federal undertaking, the Corps must …

Environmental Studies 129: Water Policy In The Western U.S., Costanza Rampini

Faculty Publications, Environmental Studies

Water, or lack of it, is the defining characteristic of development in the Western United States. Using multiple analytical frameworks, including history, law, economics, environmental science, and sociology, we will investigate the interrelationships of key policies, players, and projects involved in Western water. More specifically, we will critically examine how important federal, state, and local water policies arose and how they affect different stakeholder groups (e.g., irrigators, environmentalists, indigenous peoples, the local citizenry, government entities, public water resource agencies). We will also learn about how stakeholder values and corresponding water policies have changed, or failed to change, over time. Case …

The Relationship Between Exposure To Lead And Criminal Behavior, Margaret Meyer, Christine Rogers

2017-2018: Scott County, Iowa Health Department

In recent years it has been made apparent that exposure to lead is a significant problem for many individuals and families. Lead exposure–whether through the air, water, or by ingestion–has been linked to numerous physical, cognitive, and social problems (Chandramouli, 2009; Nevin, 2007). Furthermore, urban, poor and immigrant populations are at a higher risk for lead exposure (Bakhireva, et al., 2013). And increasingly a connection between lead exposure and criminal behavior has been identified through both correlation studies and experiments. The high cost of exposure to lead is apparent when looking at the effects of lead over a lifetime, and …

Encoding Of Emotional Valence In Wild Boar (Sus Scrofa) Calls, Anne-Laure Maigrot, Edna Hillmann, Elodie Briefer

Bioacoustics Collection

Measuring emotions in nonhuman mammals is challenging. As animals are not able to verbally report how they feel, we need to find reliable indicators to assess their emotional state. Emotions can be described using two key dimensions: valence (negative or positive) and arousal (bodily activation or excitation). In this study, we investigated vocal expression of emotional valence in wild boars (Sus scrofa). The animals were observed in three naturally occurring situations: anticipation of a food reward (positive), affiliative interactions (positive), and agonistic interactions (negative). Body movement was used as an indicator of emotional arousal to control for the effect of …

Landscape Transformation During Ceramic Age And Colonial Occupations Of Barbuda, West Indies, Allison Bain, Anne-Marie Faucher, Lisa M. Kennedy, Allison R. Leblanc, Michael J. Burn, Rebecca Boger, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This research documented the history of landscape transformation on the island of Barbuda in the Lesser Antilles, Caribbean through cross-disciplinary research approaches. Excavations confirmed a human presence for the seasonal exploitation of conch meat and other mollusks during the Archaic Age (c.3000–500 BC), but more substantial impacts to terrestrial ecosystems likely began during the Ceramic Age (c.500 BC–AD 1500). Our combined sedimentary and charcoal records revealed that human-induced environmental transformations began with Ceramic Age peoples as they cleared vegetation for settlements and gardens with intentional burning. Sedimentary charcoal indicated a dramatic decline in fire during post-Ceramic Age abandonment, continuing through …

Accounting For Spatial Autocorrelation In Modeling The Distribution Of Water Quality Variables, Lorrayne Miralha

Theses and Dissertations--Geography

Several studies in hydrology have reported differences in outcomes between models in which spatial autocorrelation (SAC) is accounted for and those in which SAC is not. However, the capacity to predict the magnitude of such differences is still ambiguous. In this thesis, I hypothesized that SAC, inherently possessed by a response variable, influences spatial modeling outcomes. I selected ten watersheds in the USA and analyzed them to determine whether water quality variables with higher Moran’s I values undergo greater increases in the coefficient of determination (R²) and greater decreases in residual SAC (rSAC) after spatial modeling. I compared non-spatial ordinary …

Vulnerability Of Protected Areas To Human Encroachment, Climate Change And Fire In The Fragmented Tropical Forests Of West Africa, Francis Kwabena Dwomoh

Electronic Theses and Dissertations

The Upper Guinean region of West Africa is home to some of the most globally significant tropical biodiversity hotspots, providing ecosystem services that are crucial for the region’s socio-economic and environmental wellbeing. Nonetheless, following decades of human-caused destruction of natural habitats, protected areas currently remain the only significant refugia of original vegetation relics in landscapes that are highly fragmented. Aside from having strong geographic variation in land use, climate, vegetation, and human population, the region has also experienced remarkable biophysical and socio-economic changes in recent decades. All these factors influence the fire regime and the vulnerability of forests within protected …

Do The Lifetime Prevalence And Prognosis Of Schizophrenia Differ Among World Regions?, Cheryl Lynn Smith

CMC Senior Theses

Much cross-cultural research has been done on the topic of schizophrenia, but few studies thus far have focused on lifetime prevalence and prognosis together, grouped by world region. Additionally, there has been severe bias in which countries and regions have been studied both historically and currently. Any study that had statistics on lifetime prevalence per 1000 people and/or DALYs, from a specified country or region, was included in this thesis. Results showed that lifetime prevalence of schizophrenia does not differ among WHO regions, but DALYs and thus prognosis do differ. Several major conclusions can be drawn from these results. One …

Examining The Influence Of Personal And Environmental Factors On Treatment Outcomes In Opioid Dependent Medication-Assisted Treatment Patients., Vierne Placide

Electronic Theses and Dissertations

Opioid abuse has become a global epidemic and is now a huge public health concern here in the US. Non-medicinal use of opioid prescription drugs is at the forefront of the epidemic and considered the "gateway" drug to other illicit opioid use. As opioid prescribing has increased over the last decade in the US, so has opioid-related deaths, surpassing car accidents and suicide as the leading cause of injury-related deaths. Medication assisted treatment (MAT) is fundamental in decreasing opioid abuse overdose and mortality. Therefore, the research study aims to determine if counseling adherence, opioid abstinence, and retention in MATs are …

“Beyond Sisterhood There Is Still Racism, Colonialism And Imperialism!” Negotiating Gender, Ethnicity And Power In Madagascar Mangrove Conservation, Manon Lefèvre

Theses and Dissertations--Geography

Understanding women’s experiences of mangrove forest conservation in the Global South is important because mangrove forests are a crucial defense against climate change, and are also increasingly the targets of global climate change policies. The intervention of postcolonial feminist theory combined with feminist political ecology has the potential to bring forward women’s seldom-heard experiences of climate change in these valuable ecosystems. This work supports previous feminist political ecology scholarship focused on understanding women’s complicated relationships to the environment and the gendered effects of climate change policies, while challenging dominant conservation discourse around women as a monolithic group. This thesis focuses …

An Empirical Investigation Of The Dimensionality Of The Physical Literacy Environment In Early Childhood Classrooms, Jaclyn M. Dynia, Rachel E. Schachter, Shayne B. Piasta, Laura M. Justice, Ann A. O'Connell, Christina Yeager Pelatti

Department of Child, Youth, and Family Studies: Faculty Publications

This study investigated the dimensionality of the physical literacy environment of early childhood education classrooms. Data on the classroom physical literacy environment were collected from 245 classrooms using the Classroom Literacy Observation Profile. A combination of confirmatory and exploratory factor analysis was used to identify five separate dimensions of the physical literacy environment; including (a) variety and use of books, (b) variety and use of writing center materials, (c) variety and use of technology, (d) variety of environmental print and (e) variety and use of other literacy-related materials. Overall, these five dimensions demonstrated reasonable reliability and validity. Implications for investigating …

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Weathering The Storm: Effects Of Storm Periods On Ancient Populations Of Coastal Florida, Brett Parbus

Electronic Theses and Dissertations

Understanding human response to natural disasters is a core problem for environmental archaeologists. Hurricanes are often devastating to coastal populations, and recognizing behavioral change in response to these major storm events provides context for the resilience and adaptability of ancient coastal people. This research project focuses on retrodicting periods of increased storm frequency and intensity for regions of the Florida coast and comparing those storm periods to the existing archaeological record in order to determine if there are correlations between increased storminess and periods of site abandonment and/or changes in subsistence strategy. These potential correlations may aid in our understanding …

Under Pressure: Explaining Backlash Against Civil Society In The Andean Community, Noah Anders Levine

Pomona Senior Theses

In this thesis, I consider the trend of increasing backlash against civil society around the world. I focus on Ecuador and Peru, both democratic countries that have placed restrictions on NGOs receiving foreign funding. I examine both countries in terms of changes over time in the regulatory environment for NGOs. I ask: What factors motivated these changes? I analyze the countries with respect to three possible explanations: defending sovereignty against foreign powers, stifling internal dissent, and seeking rents. In answering this question, I draw upon the laws in question, press releases, and news reports as well as interviews with NGO …

Managing Mining Pollution: The Case Of Water Quality Governance In The Transboundary Kootenai/Y, Ashley Juric

Graduate Student Theses, Dissertations, & Professional Papers

This thesis addresses current water quality management challenges in the transboundary Kootenai/y River Basin, and how these challenges are shaped by historical, economic, political, and social factors. The water quality of this basin, both in the United State and Canada, has been severely affected by coal mining that has occurred in British Columbia over the last hundred years and continues to be threatened by several proposed mining expansion projects. The goals of this research are to uncover the forces shaping water management and to determine the potential for interested and affected parties to participate in crafting water quality protection measures. …

From Rhetoric To Response: Climate Change, Conflict, And Development In Karamoja, Uganda, Daniel Abrahams

Theses and Dissertations

This dissertation addresses the broad question: How do the discourses of climate change and conflict travel across time and space to become policy, programming, and ultimately a development initiative that exist on the ground? To answer this question, I broke the research into three separate papers. The first examines how the US policy community approaches, understands and seeks to address the discourses of climatesecurity. The second examines the ways in which climate change affects conflict outcomes in Karamoja, Uganda. And the third, using the efforts of Mercy Corps in Karamoja as a case study, examines the realities and opportunities in …
