Vieja melanura is a Neotropical cichlid occurring in the Petén-lake district systems of Guatemala, as well as the Río Grijalva-Usumacinta basin, and other systems in Southern México, Belize, and Guatemala. A caudal stripe, extending forward from the caudal peduncle, is characteristic of this species. This stripe is sloped downward in nearly all individuals of V. melanura, but the degree of the slope is highly variable throughout its range. The slope and shape of the stripe has previously been used in diagnosing and differentiating between species of Vieja. The purpose of this …

Preservation Or Piracy: Diagnosing Low-Relief, High-Elevation Surface Formation Mechanisms, Kelin X. Whipple, Roman A. Dibiase, William B. Ouimet, Adam M. Forte Jan 2017

Preservation Or Piracy: Diagnosing Low-Relief, High-Elevation Surface Formation Mechanisms, Kelin X. Whipple, Roman A. Dibiase, William B. Ouimet, Adam M. Forte

Faculty Publications

© 2016 Geological Society of America. Absent clear lithologic control, the presence of elevated, low-relief topography in upland landscapes has traditionally been interpreted as a signature of relative surface uplift and incision of a paleo-landscape. Such interpretations are commonly supported and quantified using analyses of river longitudinal profiles under the assumption of a static drainage network topology. Drainage networks, however, are not static, and it has been proposed recently that divide migration and drainage capture can lead to the generation of low-relief upland topography that mimics that of incised paleo-landscapes and that might be falsely interpreted as recording surface uplift …

Timescales Of Landscape Response To Divide Migration And Drainage Capture: Implications For The Role Of Divide Mobility In Landscape Evolution, K. X. Whipple, A. M. Forte, R. A. Dibiase, N. M. Gasparini, W. B. Ouimet Jan 2017

Timescales Of Landscape Response To Divide Migration And Drainage Capture: Implications For The Role Of Divide Mobility In Landscape Evolution, K. X. Whipple, A. M. Forte, R. A. Dibiase, N. M. Gasparini, W. B. Ouimet

Faculty Publications

©2016. American Geophysical Union. All Rights Reserved. Efforts to extract information about climate and tectonics from topography commonly assume that river networks are static. Drainage divides can migrate through time, however, and recent work has shown that divide mobility can potentially induce changes in river profiles comparable to changes caused by variation in rock uplift, climate, or rock properties. We use 1-D river profile and 2-D landscape evolution simulations to evaluate how mobile divides influence the interpretation of river profiles in tectonically active settings. We define a nondimensional divide migration number, NDm, as the ratio of the timescale of channel …

Development Of Shale Gas Supply Chain Network Under Market Uncertainties, Jorge Chebeir, Aryan Geraili, Jose Romagnoli

Faculty Publications

The increasing demand of energy has turned the shale gas and shale oil into one of the most promising sources of energy in the United States. In this article, a model is proposed to address the long-term planning problem of the shale gas supply chain under uncertain conditions. A two-stage stochastic programming model is proposed to describe and optimize the shale gas supply chain network. Inherent uncertainty in final products' prices, such as natural gas and natural gas liquids (NGL), is treated through the utilization of a scenario-based method. A binomial option pricing model is utilized to approximate the stochastic …

Analysis Of Cost And Energy Performance Of Geothermal Heat Pump Systems In Southern Louisiana, Claudia De Lourdes Duran Tapia Jan 2017

Analysis Of Cost And Energy Performance Of Geothermal Heat Pump Systems In Southern Louisiana, Claudia De Lourdes Duran Tapia

LSU Master's Theses

In the last three decades of geothermal heat pump (GHP) industry, there has been an urge to present data, especially performance and itemized installation cost, as a plan to reduce the lack of knowledge and trust towards GHP systems for heating and cooling. The potential of GHPs in hot and humid climates is significant [Tao and Zhu, 2012]. However, past research efforts have demonstrated this potential through the use of simulation rather than real-time data. Therefore, the scope of work for this research is to investigate GHP system applications for residential buildings in areas with hot and humid climates. Based …

Ancient Maya Obsidian Trade: Arvin's Landing And Foster Farm, Belize, Kelsey Paige Johnson Jan 2017

Ancient Maya Obsidian Trade: Arvin's Landing And Foster Farm, Belize, Kelsey Paige Johnson

LSU Master's Theses

Arvin’s Landing and Foster Farm are ancient Maya settlements located on Joe Taylor Creek near Punta Gorda in southern Belize. The abundance of obsidian and the number of sources in the artifact assemblage at Arvin’s Landing and Foster Farm indicate the inhabitants of these settlement participated in long-distance trade with other Maya communities. The research was developed to examine the different geographic sources of obsidian as well as the distribution of these sources at both sites. The goal of this research is to determine whether these sites fit with existing trade patterns established by previous research over decades of obsidian …

Elephants, Local Livelihoods, And Landscape Change In Tsavo, Kenya., Peter Ngugi Kamau

LSU Doctoral Dissertations

This dissertation provides a historical context for socio-ecological relationships in Tsavo, Kenya by focusing on the interaction between elephants and people in the landscape. A better understanding of the relationship between elephants and people in the Tsavo landscape promotes opportunities for better policy outcomes. The dissertation engages with the analytical approach of political ecology, which has enabled it to provide a more nuanced understanding of the relationship between elephants and people in Tsavo. Apolitical accounts of human-elephant conflicts in Tsavo do not adequately address the colonial roots of human-elephant conflicts or their consequences for local livelihoods.

Composting The Garden: Hybrid Geographies Of Baton Rouge Urban Gardens, Lauren Hull Jan 2017

Composting The Garden: Hybrid Geographies Of Baton Rouge Urban Gardens, Lauren Hull

LSU Master's Theses

Home gardens are intimate spaces of interaction between humans and the natural world. This study examines how relations and practices within gardens both perpetuate and disrupt perspectives on human separateness from nature. Nine Baton Rouge gardeners participated in this study, sharing stories about their lives and garden through interviews and garden walk-throughs. By adopting more-than-human social theory, this study explores these stories to answer three questions: (1) What types of relationships are found between garden inhabitants in Baton Rouge? (2) How do these relationships influence garden practices? And (3) How do relationships and practices create hybrid garden spaces? Garden inhabitants …

Vertebral Pathologies And Implications For Economic Lifestyle Changes In Two Prehistoric Skeletal Populations, Alyxandra Leigh Stanco Jan 2017

Vertebral Pathologies And Implications For Economic Lifestyle Changes In Two Prehistoric Skeletal Populations, Alyxandra Leigh Stanco

LSU Master's Theses

Little research considers the vertebral column in relation to inter-populational variation and changes in economic lifestyle. Numerous studies have been conducted regarding the influence of activity-related stress on post-cranial elements such as the knees, hips and shoulders, but few studies have considered the vertebral column. This study examined the vertebral columns of two prehistoric skeletal populations. The Indian Knoll site, home to a population of early hunter-gatherers, is located in Ohio County, Kentucky along the Green River. Indian Knoll was first excavated in 1915 by C.B. Moore. The Moundville site, a chiefdom of early agriculturalists, is located in the Black …

Pronoun Marking In African American English-Speaking Children With And Without Specific Language Impairment, Gayatri Ramamoorthy Brown Jan 2017

Pronoun Marking In African American English-Speaking Children With And Without Specific Language Impairment, Gayatri Ramamoorthy Brown

LSU Master's Theses

The present study was designed to describe and quantify patterns of pronoun use by African American English (AAE)-speaking children with specific language impairment (SLI) relative to their AAE-speaking typically developing (TD) peers. Pronouns were of interest because: they are produced frequently in everyday speech, they are often targeted when a child’s language abilities are evaluated by a speech-language pathologist, and limited pronoun data exists for AAE-speaking children. The data were language samples that had been elicited from 96 children (35 SLI, 61 TD) enrolled in kindergarten. The samples were searched for 11 different pronoun forms, and these were coded as …

Non-Metric Cranial Differentiation Between Asian And Native American Populations For Ancestry Assessment, Dominique Marie Bodoh Jan 2017

Non-Metric Cranial Differentiation Between Asian And Native American Populations For Ancestry Assessment, Dominique Marie Bodoh

LSU Master's Theses

Assessing ancestry from skeletal remains provides important information to aid in personal identification. However, trying to specify ancestry for Native American and Asian populations in the United States is a current challenge in laboratory analyses. Both Native American and Asian populations are still often combined in research for a variety of reasons: small sample sizes, skeletal similarities and less emphasis in contemporary literature. Historically, Carlton Coon, in 1939, and Riesenfield, in 1956, refer to this combination of both Native American and Asian populations as “Mongoloid,” a term which is deemed by many as an offensive and inaccurate categorization of both …

A Comparative Study Of The Effects Of River Flow Rates On Decomposition, Maddisen Paige Neuman Jan 2017

A Comparative Study Of The Effects Of River Flow Rates On Decomposition, Maddisen Paige Neuman

LSU Master's Theses

While the general biological processes of decomposition are known to forensic anthropologists, data on aquatic decomposition is in need of refinement. Water composition varies in mineral content, temperature, flow rate, and scavengers; each of these elements can have an effect on the rate of decomposition. This study specifically focuses on the effects of river flow rates on decomposition by comparing the rate of decay of three feral pigs (Sus scrofa) on land (control specimen), in faster flowing water, and in slower flowing water. The hypothesis states that the pig placed in the faster section of the river will decompose more …

Impacts Of Enso On Tornado Frequency, Intensity, And Geography Across The Eastern United States, Coryn Ann Collins Jan 2017

Impacts Of Enso On Tornado Frequency, Intensity, And Geography Across The Eastern United States, Coryn Ann Collins

LSU Master's Theses

Tornadoes are a reoccurring severe weather hazard, with the highest rates globally occurring in the central United States. Despite their high frequency in the U.S., the scientific community’s disagreement of tornado activity during varying phases and intensities of the El Niño Southern Oscillation (ENSO) justifies a need for further research. In this study, tornado events from 1950 to 2014 in the U.S. east of the Rocky Mountains were investigated for seven phases of ENSO: strong, moderate, and weak El Niño/La Niña and the neutral phase. A seasonal Niño 3.4 index was used as the definition of ENSO. ENSO influences on …

Pots, Pans, And Politics: Feasting In Early Horizon Nepeña, Peru, Kenneth Edward Sutherland Jan 2017

Pots, Pans, And Politics: Feasting In Early Horizon Nepeña, Peru, Kenneth Edward Sutherland

LSU Master's Theses

This thesis explores Early Horizon (900 – 200 BCE) feasting practices visible through the pottery assemblage at three archaeological complexes in the lower Nepeña Valley, north-central coast of Peru. Ceramic vessels were used for production, transportation, and storage of foods consumed for daily subsistence and during feasting events at the settlement of Caylán, a large town or city interpreted as the primary center of a multi-tiered polity. Secondary settlements at Samanco, a small coastal town, and Huambacho, an elite ceremonial center, indicate the complexity of this polity. Analysis of ceramic rim sherds reveals the types of vessels used at these …

Evolutionary History Of A Large-Genome Salamander Across Five Disjunct Regions Of The Southeastern United States, Catherine Elizabeth Newman Jan 2017

Evolutionary History Of A Large-Genome Salamander Across Five Disjunct Regions Of The Southeastern United States, Catherine Elizabeth Newman

LSU Doctoral Dissertations

The southeastern United States has a dynamic geologic history. Mountain range uplift, sea level fluctuations, and river basin evolution have shaped species geographic distributions in the region. My dissertation objectively identifies amphibian species with highly fragmented distributions in the Southeast (Chapter 2) and examines the phylogeographic history of one of those species, Plethodon serratus. This salamander species has a widely disjunct range across five regions: the Appalachians, the Ozarks, the Ouachitas, and two allopatric sites in Louisiana. Analyses of mitochondrial and nuclear loci (Chapter 3) showed that P. serratus is comprised of multiple genetic lineages, and the five regions are …

Descendants Of Abraham: A Comparative Approach To Jewish And Islamic Rhetorics, Brandon Katzir Jan 2017

Descendants Of Abraham: A Comparative Approach To Jewish And Islamic Rhetorics, Brandon Katzir

LSU Doctoral Dissertations

Descendants of Abraham: A Comparative Approach to Jewish and Islamic Rhetorics provides two important correctives to modern scholarship. It emphasizes the importance of Jewish and Islamic rhetorics typically neglected by Western-centric historians of rhetoric, and it showcases the cultural relationship between Jews and Muslims that has been typically occluded by modern scholarship. Focusing on the early Islamic world, I demonstrate instantiations of interconnectivity between Jewish and Islamic rhetoric in Arabic from the 9th-12th centuries CE. Specifically, I look at how judicial rhetoric plays an important role in the adjudication of halakha and sharia, followed by a consideration of theological rhetoric …

The Fooding Of Narrative In Contemporary Women's Transnational Fiction, Stacey Marie Amo Jan 2017

The Fooding Of Narrative In Contemporary Women's Transnational Fiction, Stacey Marie Amo

LSU Doctoral Dissertations

The Fooding of Narrative in Contemporary Women’s Transnational Fiction examines how foodstuffs are strategically deployed in recent fiction about migration to the United States. The novels examined, all set in the period following the passage of the Immigration and Nationality Act of 1965, depict the experience of resettlement from a diverse set of postcolonial sites: Haiti, Cuba, Vietnam, and India. The Fooding of Narrative argues that food is deployed as a structuring trope and acquires narrative significance in articulating the profound sense of identity crisis that frequently accompanies the immigration experience. By focusing on food’s narrative significance in a broad …

A Palynostratigraphic Investigation Of Holocene Coastal Texas Bays: Implications For Future Coastal Change, Shannon Marie Ferguson Jan 2017

A Palynostratigraphic Investigation Of Holocene Coastal Texas Bays: Implications For Future Coastal Change, Shannon Marie Ferguson

LSU Doctoral Dissertations

Although the Gulf of Mexico is one of the most studied basins in the world, a majority of the focus has been driven by petroleum exploration and/or on seismic and sedimentological facies models. Rarely has the intent of previous studies been to characterize the Holocene climatic record of coastal Texas. Of those studies that discuss Holocene vegetation change, the majority focus on the Mississippi River Delta, the Edwards Plateau or central Florida, leaving an absence of insight to western Gulf of Mexico climate changes. The Texas coastline stretches 595 km across almost 4° of latitude and the strong northwestern precipitation …

Brazilian Surface And Upper-Level Wind Characteristics Based On Ground And Model Observations From 1980–2014, Joshua M. Gilliland Jan 2017

Brazilian Surface And Upper-Level Wind Characteristics Based On Ground And Model Observations From 1980–2014, Joshua M. Gilliland

LSU Doctoral Dissertations

The examination of temporal changes in surface winds has been analyzed by scientists for a variety of physical, biological, climatological, and socioeconomic reasons. This research uses surface and upper-level wind data from historical in-situ and climate models to examine the geographical and climatological characteristics of wind across Brazil during 1980–2014. Overall linear and quantile regression shows that surface wind speed trends are changing regionally across Brazil. Wind speeds across northeastern Brazil are increasing, while a decreasing trend is documented for interior and southeastern Brazil. The spatial and temporal trends found are possibly related to alterations in the physical landscape (urbanization …
