"Waste Is Not Just Waste Anymore": Deconstructing The Relationship Between Sustainable Waste Prevention And Individual Socio-Demographic Characteristics (The Juxtaposition Of Ushongo Mtoni Village And Moshi Urban, Tanzania), Mahalia Smith
Independent Study Project (ISP) Collection
I am going to tell you a story about humans — their lives, livelihoods, environments, and their individual relationships to sustainable waste prevention. As developing countries, such as Tanzania experience economic growth, waste overflow and proper waste disposal become even more arduous challenges. Thus, it is becoming increasingly important to explore sustainable solutions such as waste prevention. Through conducting semi-structured interviews in two distinctly unique locations, Moshi Urban of the Kilimanjaro Region and Ushongo Village on the coast of Tanga Region, Tanzania, I explored how levels of awareness and involvement in sustainable waste prevention practices, specifically reducing, reusing, and recycling, …

Towards Predicting Risky Behavior Among Veterans With Ptsd By Analyzing Gesture Patterns, Tanvir Roushan
Towards Predicting Risky Behavior Among Veterans With Ptsd By Analyzing Gesture Patterns, Tanvir Roushan
Master's Theses (2009 -)
Risky behavior including violence and aggression, self-injury, anger outburst, domestic violence along with self-injury, sexual abuse, rule breaking, use of drugs and alcohol, suicide etc. are alarming issues among US military veterans who return from combat zone deployment in Iraq and Afghanistan. Veterans are exposed to trauma in war zones which affect most of them with posttraumatic stress disorder (PTSD) or other metal health problems to some degree. Studies have shown that veterans have much higher rates of PTSD than civilians and are more likely to engage in risky behavior. One of the form of displaying and engaging in risky …
An Evaluation Of The Utility Of A Mass-Weighted Frequency Distribution Of Sediment For Modeling Aeolian Transport Rates, Raihan Jamil
An Evaluation Of The Utility Of A Mass-Weighted Frequency Distribution Of Sediment For Modeling Aeolian Transport Rates, Raihan Jamil
LSU Master's Theses
Predictions made by aeolian transport models often do not match well with measured data. The poor predictive capability of these models remains a fundamental problem in aeolian geomorphology. This study evaluates the effectiveness of the recently proposed mass-weighted frequency distribution (Edwards and Namikas 2015) and the apparent von Kármán parameter proposed by Li et al. (2010) to improve transport rate predictions. The evaluation consists of comparisons of predicted transport rates versus a large dataset of measured field and lab transport rates collected from the literature. The transport rate predictions are made both with and without recalibration of model empirical coefficients. …
Perception & Perspective: An Analysis Of Discourse And Situational Factors In Reference Frame Selection, Robert J. Ross, Kavita E. Thomas
Perception & Perspective: An Analysis Of Discourse And Situational Factors In Reference Frame Selection, Robert J. Ross, Kavita E. Thomas
Conference papers
To integrate perception into dialogue, it is necessary to bind spatial language descriptions to reference frame use. To this end, we present an analysis of discourse and situational factors that may influence reference frame choice in dialogues. We show that factors including spatial orientation, task, self and other alignment, and dyad have an influence on reference frame use. We further show that a computational model to estimate reference frame based on these features provides results greater than both random and greedy reference frame selection strategies.
Urban Animals: Gis Analysis Of Stray Canines And Felines In Albuquerque, New Mexico, Courtney Brock
Urban Animals: Gis Analysis Of Stray Canines And Felines In Albuquerque, New Mexico, Courtney Brock
Geography ETDs
While human influence and progress has shaped the cityscape of Albuquerque, New Mexico, many stray animals also consider this city to be their home. Albuquerque’s Animal Welfare Department holds a human responsibility over these urban animals and their habitat displacement, requiring them to either be registered and owned or euthanized. Although animal rights are a topic continually in debate, the habitat choices made by stray animals are rarely questioned, due to anthropocentrism in the city’s structure and laws.
Through observational field research with Albuquerque’s Animal Welfare Officers, stray animal locations were collected throughout the city for one week in July …

USF Tampa Graduate Theses and Dissertations
This dissertation examines the public health impacts of a large dam project on a downstream community using the framework of Syndemic Theory. The particular focus is the Belo Monte Dam, located in the Brazilian Amazon, and its impact on the community of Gurupá, Pará. At the present time the Belo Monte Dam, which is nearing completion, stands out in scale as being the world’s third largest dam complex. Gurupá is a community well known (and well-studied) in the social science literature as Amazon Town. The aims of this study are to assess the pre-existing public health of Gurupá, as well …
Madden-Julian Oscillation Relationships With Cool Season Cyclogenesis, Daily Precipitation, And Cool Season Severe Weather Frequencies In The Gulf Of Mexico Region, Stephen Paul Caparotta
Madden-Julian Oscillation Relationships With Cool Season Cyclogenesis, Daily Precipitation, And Cool Season Severe Weather Frequencies In The Gulf Of Mexico Region, Stephen Paul Caparotta
LSU Doctoral Dissertations
Tropical cyclone variability in the Gulf of Mexico (GoM) has been the focus of a considerable amount of research. Variability on both interannual scales, related to the El Niño-Southern Oscillation (ENSO), and on subseasonal scales, related to the Madden-Julian Oscillation (MJO), is well documented. By contrast, very little research exists on the relationships between the MJO and cool season, non-tropical cyclones in the GoM.
The MJO influence on cool season (October-March) cyclogenesis in the GoM variability is explored here. Additionally, daily precipitation variability and cool season severe weather variability is examined for areas near and just inland of the GoM. …

Topographic Maps: Image Processing And Path-Finding, Calin Washington
Topographic Maps: Image Processing And Path-Finding, Calin Washington
Master's Theses
Topographic maps are an invaluable tool for planning routes through unfamiliar terrain. However, accurately planning routes on topographic maps is a time- consuming and error-prone task. One factor is the difficulty of interpreting the map itself, which requires prior knowledge and practice. Another factor is the difficulty of making choices between possible routes that have different trade-offs between length and the terrain they traverse.
To alleviate these difficulties, this thesis presents a system to automate the process of finding routes on scanned images of topographic maps. The system allows users to select any two points on a topographic map and …
Dental Measurements Do Not Diagnose Modern Artiodactyl Species: Implications For The Systematics Of Merycoidodontoidea, Meaghan M. Emery-Wetherell, Edward Byrd Davis
Dental Measurements Do Not Diagnose Modern Artiodactyl Species: Implications For The Systematics Of Merycoidodontoidea, Meaghan M. Emery-Wetherell, Edward Byrd Davis
All Faculty Scholarship for the College of the Sciences
Though dental measurements are frequently used to diagnose the fossil species of Merycoidodontoidea and other extinct artiodactyls, the effective diagnosis of modern artiodactyl taxa via dental measurements has not been extensively tested. Our study finds that variation in artiodactyl dentition is generally higher than in primates, carnivores, rodents and even elephants, with molar coefficients of variation ranging up to 18% (Camelus bactrianus), and that dental measurements poorly diagnose modern artiodactyls via discriminant function analysis, adjusted t -tests on coefficients of variation, or finite mixture analysis. The higher-than-expected coefficients of variation for artiodactyls imply that some fossil taxa may …
The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly
The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly
Humboldt Journal of Social Relations
In the wake of the timber wars, communities across the American West have struggled to redefine their relationships to nearby federal forests. The timber-dependent model of the pre-Timber War era, with clear timber targets and economic outputs, has been replaced by more nuanced and less clearly-defined model: ecosystem management. This case study research uses interviews with participants in the Weaverville Community Forest (WCF) to explore the role of a community in managing its nearby federal lands. Momentum for the WCF flowed from a small group of citizens who were invested in the forest despite their cultural and ideological differences regarding …
A Novel Multiproxy Approach To Reconstructing Sea Surface Temperature In The Southwestern Gulf Of Mexico, Marissa Anne Vara
A Novel Multiproxy Approach To Reconstructing Sea Surface Temperature In The Southwestern Gulf Of Mexico, Marissa Anne Vara
LSU Master's Theses
Coral Sr/Ca is a widely-used proxy for sea surface temperature (SST); however, discrepancies in the coral Sr/Ca-SST relationship among colonies of the same species makes uncertainty in absolute temperature reconstructions larger than the climate signal yet climate variability studies are possible. Furthermore, the riverine input of terrestrial carbonate weathering products to the coastal waters can disrupt the coral Sr/Ca-SST signal by changing local seawater chemistry. This study evaluates the fidelity and reproducibly of coral SST proxies (Sr/Ca, Li/Ca, Mg/Li, Sr-U, Mg/Ca, and U/Ca) and a riverine-upwelling proxy (Ba/Ca) in four Orbicella faveolata colonies in two reefs offshore from Veracruz, Mexico …

LSU Master's Theses
A cluster of previously buried Taxodium distichum stumps are exposed and preserved in growth position at the bottom of a trough on the inner Gulf of Mexico (GOM) continental shelf in 18 m water depth and 13 km offshore Orange Beach, AL. Radiocarbon ages from wood and optically stimulated luminescence (OSL) dating of sediments suggest a Marine Isotope Stage (MIS) 3 age, or older. This study builds on the previous work of Gonzalez (2018) and Obeclz (2017). Five biofacies were identified in vibracore collected in 2015 and 2016: 1) the Holocene Mississippi-Alabama-Florida (MAFLA) sand sheet, 2) a Holocene interbedded sand …

Water Quality Assessment Of The Lower Cache And The Bayou Deview Rivers, Arkansas: An Assessment Of Nutrients, Sediment, Lead, And Acute Toxicity Of Acephate And Thiamethoxam, Carlos Alberto Rosado-Berrios
Student Theses and Dissertations
The Cache River Watershed (CRW) is located in northeast Arkansas and flows through the Delta Ecoregion. The CRW has been modified for agricultural use, especially in the upper section where it was channelized decades ago. Its designated uses by Arkansas Department of Environmental Quality (ADEQ) are for fish and wildlife propagation, primary and secondary recreation, and as a water source for domestic, agricultural and industrial supply. Unfortunately, the standards for these designated uses are not met due to the presence of toxic metals, elevated chloride levels, and dissolved solids. Consequently, the CRW is cited on the 303d list of the …

Nitrous Oxide Emissions From Rice Production On A Silt-Loam Soil In Arkansas, Casey Rector
Nitrous Oxide Emissions From Rice Production On A Silt-Loam Soil In Arkansas, Casey Rector
Graduate Theses and Dissertations
Rice (Oryza sativa L.) is a common crop grown in Arkansas under flooded-soil conditions. The saturated to nearly saturated soil makes rice production an ideal environment for the production of potent greenhouse gases, such as nitrous oxide (N2O). The objectives of this study were to i) evaluate the impact of water management practice (full-season-flood and intermittent-flood) and cultivar (pure-line and hybrid) on N2O fluxes, season-long N2O emissions, and global warming potential (GWP; 2016) and ii) evaluate the impact of tillage practice [conventional tillage and no-tillage (NT)] and type of urea fertilizer [ N-(n-butyl) thiosphosphoric triamide (NBPT)-coated and non-coated urea] on …

Freshwater Reservoir Offsets And Food Crusts: Isotope, Ams, And Lipid Analyses Of Experimental Cooking Residues, John P. Hart, Karine Taché, William A. Lovis
Freshwater Reservoir Offsets And Food Crusts: Isotope, Ams, And Lipid Analyses Of Experimental Cooking Residues, John P. Hart, Karine Taché, William A. Lovis
Publications and Research
Freshwater reservoir offsets (FROs) occur when AMS dates on charred, encrusted food residues on pottery predate a pot’s chronological context because of the presence of ancient carbon from aquatic resources such as fish. Research over the past two decades has demonstrated that FROs vary widely within and between water bodies and between fish in those water bodies. Lipid analyses have identified aquatic biomarkers that can be extracted from cooking residues as potential evidence for FROs. However, lacking has been efforts to determine empirically how much fish with FROs needs to be cooked in a pot with other resources to result …
Furs: Functionality, Fashion, And Franchise, Jenna Q. Detweiler
Furs: Functionality, Fashion, And Franchise, Jenna Q. Detweiler
Environment and Sustainability Honors Papers
Animal furs have been used in various manners through human history. Early humans cut crude shawls for warmth, and with the development of tools such as needles, closer-fitting clothing such as fur pants became possible. As time went on, products such as wool and cotton were used for clothing and, with fur alternatives, furs were reserved for the ultra-wealthy in some cultures. The image of fur as a luxury item has remained ever since, but simultaneously fur has become more accessible to the general public. Meanwhile, animal rights movements have successfully dampened interest in fur in some countries and communities. …

The Association Of Size Variation In The Dental Arch To Third Molar Agenesis For A Modern Population, Devin N. Williams
USF Tampa Graduate Theses and Dissertations
The frequency with which individuals do not develop their third molars, or wisdom teeth, is increasing worldwide. This current topic of human evolution is relevant to the research of anthropologists, geneticists, dentists, and other researchers involved in the study of human dentition. Many explanations have been offered to account for the prevalence of molar agenesis including, evolutionary, environmental, and genetic theories. The purpose of this research project is to determine the frequency of third molar agenesis and investigate the relationship between third molar agenesis and maxillomandibular jaw dimensions in a sample of orthodontic patients. This research tests the hypotheses that: …

Virtuous Discourse In The Specialty Coffee Sector: How Social Responsibility Practices Fragment Pursuits For A Supply Chain, Jane H. Motsinger
Geography ETDs
A diversity of public and private initiatives strive to address the human-environment challenges confronting the global coffee industry, including certifications like Fairtrade, direct trade sourcing models, and efforts led by NGOs. Research examines the outcomes of major certification programs and the private initiatives of corporations like Starbucks. Much less is known about the business practices of the small specialty coffee businesses that increasingly advertise sustainable business practices. Yet, their collective business practices likely influence the industry-wide efforts to achieve a sustainable supply chain. This research examines how small specialty coffee roasting and importing companies represent their socially responsible business practices …
