Metacarpal Ratio And Its Relation To Sexual Dimorphism In Primates With Different Mating Strategies, Emilee Hart
Metacarpal Ratio And Its Relation To Sexual Dimorphism In Primates With Different Mating Strategies, Emilee Hart
LSU Master's Theses
The digit ratio (2D:4D) is a sexually dimorphic trait in mammalian hands that is a result of levels of prenatal androgen exposure (PNAE) during limb development. Previous studies have shown that females have a higher ratio than males and that sexual dimorphism in the ratio is greater in species with polygynous mating strategies and high levels of intermale aggression compared to monogamous species with low intermale aggression. This study used metacarpals instead of phalanges to test the hypotheses that the metacarpal ratio (2Mc:4Mc) will be higher in females than males within a species and that the ratio would be more …

LSU Master's Theses
This thesis studies Iranian student immigrants in the United States in the special political tensions between the two countries from 2000 until present. This research provides a holistic view of understanding the new identity which Iranian students have reconstructed at the intersection of Iranian culture and U.S. culture through their past identity in confronting a new situation. It describes how Iranian students use individual, intellectual, and social resources to deal with the ignorance was that imposed on them when the governments of the two countries began to fight each other to achieve more political power. Data is collected from three …
Development Of A Literary Dispositif: Convening Diasporan, Blues, And Cosmopolitan Lines Of Inquiry To Reveal The Cultural Dialogue Among Giuseppe Ungaretti, Langston Hughes, And Antonio D’Alfonso, Anna Ciamparella
LSU Doctoral Dissertations
This dissertation seeks to create a literary dialogue among the Italian poet Giuseppe Ungaretti, the African American author Langston Hughes, and the Quebecois writer Antonio D’Alfonso. Giuseppe Ungaretti and Langston Hughes were more or less contemporaries. Ungaretti was born in 1888 and Hughes in 1902, and both were active in modernist movements that shaped the literary history of their own countries. D’Alfonso was born in Canada about half a center after Ungaretti and Hughes. Besides significant generational differences, these three authors also underwent personal and intellectual experiences that shaped their writing in seemingly incomparable ways. While a traditional comparative approach …
Press To Stop, Garrett Duncan Hazelwood
Press To Stop, Garrett Duncan Hazelwood
LSU Master's Theses
In the wake of a performance art piece in which the audience kills one of the performers and maims the other, the surviving artist is put on display in art galleries by his family. The public clamors to see him, protests against his exploitation rock the city, and intrigue surrounds his sudden rise to fame. In the end, a religion is founded in his honor and his best friend must make a terrible choice about whether or not to save him.
Relating Diets And Food Availability To Long-Term Population Trends Of Lesser Scaup Wintering On Lake Pontchartrain, Louisiana, Clay Michael Stroud
Relating Diets And Food Availability To Long-Term Population Trends Of Lesser Scaup Wintering On Lake Pontchartrain, Louisiana, Clay Michael Stroud
LSU Master's Theses
Lake Pontchartrain provides wintering habitat for a continentally-significant proportion of lesser scaup (Aythya affinis). Mid-winter aerial surveys indicate dramatic variation in annual scaup abundance (0–1,194,907), though the mechanisms driving fluctuations have not been previously investigated. In response to natural and anthropogenic disturbances, species composition, abundance, and size structure of benthic invertebrate populations in Lake Pontchartrain exhibit drastic variability among years. Given that wintering scaup feed primarily on mollusks, environmental disturbances have the potential to influence scaup dynamics on the estuary by altering the benthic community. To diagnose trophic linkages and variation in scaup abundance, we collected ducks (n=60) …
Preservation And Reformation, Yedi Zhang
Preservation And Reformation, Yedi Zhang
LSU Master's Theses
ABSTRACT Taking the conservation and development of the Old Town of Luoyang as an example, this thesis explores the issue of largescale renovation and reconstruction of old city in the background of urbanization, and attempts to seek the balance between old town preservation and local residents’ life quality enhancement. It is needing to be aware that, as a result of the layering and intertwining of cultural and natural values over time, the urban historical heritage includes both tangible and intangible components. To protect historical heritage in the city, we should not only just imitate the history scenes, more importantly, it …
Linguistic Political Ecology With The Ngäbe Indigenous People Of Panama, Ginés A. Sánchez Arias
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 …
Essays On Estimation For Nonlinear Spatial Models, Xiaoyu Zhou
Essays On Estimation For Nonlinear Spatial Models, Xiaoyu Zhou
LSU Doctoral Dissertations
This dissertation consists of three essays that contribute to the literature on the estimation of nonlinear spatial panel models. Chapter 2 investigates the performance of both the spatial autocorrelation probit model (SAR) and the spatial error correlation probit model (SEM) with the consideration of temporal effects under the panel data framework. The recursive importance sampling (RIS) method is adopted to compute the integral of the multivariate normal distributed error terms. Chapter 3 estimates a panel probit model with individual fixed effects. A spatial error process and conditional heteroskedasticity in an exponential form is considered. We derive the analytical solution for …
An Index For Measuring Community Resilience To Flooding In Baton Rouge, Louisiana, Yi Ling Chan
An Index For Measuring Community Resilience To Flooding In Baton Rouge, Louisiana, Yi Ling Chan
LSU Master's Theses
The greater Baton Rouge area in Louisiana has been impacted by repeated floods throughout its history. The most recent flood in August 2016 resulted in damages to over 80,000 homes and businesses and upwards of $430 million in public assistance granted by the Federal Emergency Management Agency. East Baton Rouge Parish and neighboring Livingston and Ascension parishes are expected to face compounded pressures and risks with the threat of increasing frequency of flood events coupled with expanding populations due to continuing suburbanization and inland migration from those living on Louisiana's coast. The purpose of this research is to create and …

Rebel Governance In Civil War: Variations In Rebel Governance - A Case Study Analysis., Harriet Ann Sellers
Rebel Governance In Civil War: Variations In Rebel Governance - A Case Study Analysis., Harriet Ann Sellers
LSU Master's Theses
Insurgent groups vary in how they interact with civilians. Some insurgent groups perform government functions to further their political objectives during civil war, whilst other rebel groups use solely violent means. Why do some insurgent groups perform governance functions to further their political objectives, whilst others interact very little with the local population? I seek to explain the variation in rebel governance, which I argue is motivated by the objective of the insurgency. More specifically, I argue that secessionist insurgencies are more likely to implement governance structures than non-secessionist insurgent groups. Using an in-depth case study analysis, I found varying …
Operational Impact Of Shadow Evacuation On Regional Road Networks During Short-Notice Emergency Evacuations, Efe Emre Tuncer
Operational Impact Of Shadow Evacuation On Regional Road Networks During Short-Notice Emergency Evacuations, Efe Emre Tuncer
LSU Master's Theses
As part of evacuation planning, development of effective tactical and operational strategies are essential to safely and efficiently mobilize the public away from the threat. Evacuations are classified by the time between notification and the anticipated arrival of the threat which can be categorized as short, or no-notice emergencies. Emergencies involve the computation of the time required to evacuate the area of risk, which is the time to clear a radius of up to about 10-miles around the nuclear power plant, known as the emergency planning zone (EPZ). These evacuation time estimates (ETE) also account for the evacuation of the …
Analysis Of Marine Sediment By Chemical Signatures And Loss-On Ignition To Discover Evidence Of Ancient Maya Activities At Site 74, Paynes Creek Salt Works, Belize, Kobi Weaver
LSU Master's Theses
In this thesis, archaeological sediment chemistry, loss-on ignition and microscopic analysis of marine sediment are used to study Site 74 of the Paynes Creek Salt Works in southern Belize. Site 74 was once an ancient Maya salt work. Due to sea-level rise, sea water and mangrove peat now cover the site. Sediment from the site was exported under permit to the Louisiana State University Laboratory. I prepared and delivered the samples to the Louisiana State University Agricultural Chemistry Laboratory for inductively coupled plasma- atomic emission spectroscopy testing (ICP-AES). ICP-AES measured the amount of 20 elements in the sediment. Maps showing …
The Impact Of Cultural Attitudes On Economic Outcomes And The Political Behavior Of Blacks, Jhacova Williams
The Impact Of Cultural Attitudes On Economic Outcomes And The Political Behavior Of Blacks, Jhacova Williams
LSU Doctoral Dissertations
In this dissertation, I offer two distinct studies on cultural attitudes. In the first study, I analyze the extent to which the political participation of blacks can be traced to historical lynchings that took place between 1882 and 1930 in the same counties. Using county-level voter registration data, I show that blacks who reside in southern counties that experienced a relatively higher number of historical lynchings have lower voter registration rates today. This relationship holds after accounting for a variety of historical and contemporary characteristics of counties and strengthen when lynchings are instrumented with historical measures of environmental suitability for …
Topographic Control On Post-Lgm Groundings Of The West Antarctic Ice Sheet In The Whales Deep Basin, Eastern Ross Sea, Matthew Danielson
Topographic Control On Post-Lgm Groundings Of The West Antarctic Ice Sheet In The Whales Deep Basin, Eastern Ross Sea, Matthew Danielson
LSU Master's Theses
By the peak of the Last Glacial Maximum (LGM), the West Antarctic Ice Sheet (WAIS) had advanced to the outer continental shelf of eastern Ross Sea trough basins. During the post-LGM retreat, the WAIS paused several times within 75 km of the Whales Deep Basin (WDB) shelf edge. An overlapping stack of seven grounding zone wedges (GZWs) records the locations of these groundings. Here we used ~7500 km of seismic reflection data to map the subglacial unconformity that was eroded when WAIS was grounded at the shelf edge, i.e., prior to the deposition of the backstepping GZWs. With respect to …
Ethnicity, Climate, And House Types As Mortality Factors In The New Orleans' 1878 Yellow Fever Outbreak, Gabriele Richardson
Ethnicity, Climate, And House Types As Mortality Factors In The New Orleans' 1878 Yellow Fever Outbreak, Gabriele Richardson
LSU Doctoral Dissertations
The following study is first a demonstration that even incomplete health data from 1878 New Orleans’ yellow fever outbreak can be used with modern epidemiological methods and achieve useful and revealing results. Accordingly, this research examines three possible associations between New Orleans’ population exposed to yellow fever and the environment they lived in, using 4,755 yellow fever cases, derived from the New Orleans Board of Health report, Cemetery Burial records, Hospital, Asylum, and prison registers, and New Orleans obituaries. The first relationship addresses the vulnerability to yellow fever for people born in Italy, France, Great Britain, and the German Empire, …
Providing Information And Public Outreach Across Three U.S. State Archaeology Offices During The Age Of Open Access, Samuel Thomas Ayers
Providing Information And Public Outreach Across Three U.S. State Archaeology Offices During The Age Of Open Access, Samuel Thomas Ayers
LSU Master's Theses
Archaeology in the United States has been transformed into a mainstream, practical science over the past fifty years by Cultural Resource Management (CRM) and the federal regulations imposed by the National Historic Preservation Act (NHPA) of 1966. However, this form of archaeology has been plagued with criticisms since the NHPA’s enactment including issues of access and use of data maintained by state site files. State archaeology is publicly funded yet state and federal legislation often exempts CRM data from freedom of information laws. To mitigate this contradiction and stem the growing body of “gray literature”, new open-access (OA) technologies are …

© 2018 The Author(s) Published by the Royal Society. All rights reserved. The distribution of parasites across mammalian hosts is complex and represents a differential ability or opportunity to infect different host species. Here, we take a macroecological approach to investigate factors influencing why some parasites show a tendency to infect species widely distributed in the host phylogeny (phylogenetic generalism) while others infect only closely related hosts. Using a database on over 1400 parasite species that have been documented to infect up to 69 terrestrialmammal host species,we characterize the phylogenetic generalism of parasites using standard effect sizes for three metrics: …

Public Knowledge Of Monarchs And Support For Butterfly Conservation, Jerrod Penn, Hannah Penn, Wuyang Hu
Faculty Publications
© 2018 by the authors. Pollinator populations in North America are in decline, including the iconic monarch butterfly. In order to determine if public knowledge of monarchs informs opinions on butterfly conservation, we surveyed the public to assess their knowledge of monarchs. We also asked participants about their attitudes towards general butterfly conservation and if they believe that butterfly gardens contribute to conservation. Respondents generally had some knowledge of monarchs but were unaware of monarch population declines and the necessity of milkweed to their life cycle. Respondent knowledge was correlated with more positive attitudes about butterfly conservation. Furthermore, membership in …

Assessment of the response of streamflow to future climate change in headwater areas is of a particular importance for sustainable water resources management in a large river basin. In this study, we investigated multiscale variation in hydroclimatic variables including streamflow, temperature, precipitation, and evapotranspiration in the Headwater Areas of the Nenjiang River Basin (HANR) in China's far northeast, which are sensitive to climate change. We analyzed 50-year-long (1961-2010) records of the hydroclimatic variables using the ensemble empirical mode decomposition (EEMD) method to identify their inherent changing patterns and trends at the inter-annual and inter-decadal scales. We found that all these …

© 2018 The Authors. This study shows that the cosmogenic radionuclide beryllium-7 can be used to track sediment movement through caves. The activities of beryllium-7 and cesium-137 were measured in two different karst settings at both surface and subsurface sites before and after storm runoff events. At one site, 7Be-enriched sediment was detected up to 1.5 km along a stream conduit after a moderate storm event; however, the activity of 137Cs was too variable to show a meaningful pattern. The percentages of surface sediment that was found ranged from 0 to 52% along the entire 3 km cave stream and …

The Ciénaga Grande de Santa Marta (CGSM) is one of the world's most productive tropical wetlands and one that has witnessed some of the greatest recorded dieback of mangroves. Human-driven loss of hydrologic connectivity by roads, artificial channels and water flow regulation appears to be the reason behind mangrove mortality in this ungauged wetland. In this study, we determined the CGSM's current state of hydrologic connectivity by combining a remote sensing technique, termed as Wetland Interferometric Synthetic Aperture Radar (InSAR), with a hydrologic study of river water discharge. For this research, we processed 29 ALOS-PALSAR acquisitions taken during the period …

Cambial Phenology Informs Tree-Ring Analysis Of Fire Seasonality In Coastal Plain Pine Savannas, Monica T. Rother, Jean M. Huffman, Grant L. Harley, William J. Platt, Neil Jones, Kevin M. Robertson, Steve L. Orzell
Faculty Publications
© 2018, The Author(s). Understanding of historical fire seasonality should facilitate development of concepts regarding fire as an ecological and evolutionary process. In tree-ring based fire-history studies, the seasonality of fire scars can be classified based on the position of the fire scar within or between growth rings. Cambial phenology studies are needed to precisely relate a fire-scar position to months within a year because the timing of dormancy, earlywood production, and latewood production varies by species and location. We examined cambial phenology patterns of longleaf pine (Pinus palustris Mill.), slash pine (P. elliottii Engelm.), and South Florida slash pine …
