A Poetics Of Temperance: Gender, Genre, And Meaning-Making In Early Modern England, Cristina Maria Rosell

LSU Doctoral Dissertations

For several hundred years, the scholarly discussion of temperance was dominated by the legacy of classical models. This dissertation, titled A Poetics of Temperance: Gender, Genre, and Meaning-Making in Early Modern England, develops said discussion in a new way by forging a language about ethics and aesthetics into a poetics of temperance. The term poiesis derives from Greek and signifies “to make, create, produce” (OED). Accordingly, Aristotle uses the Greek poietes, “from which our word ‘poet’ derives,” to denote a “maker” (Murray xxxii). In brief, this project understands the role of women in emergent genres as …

Identification Of Experimental And Control Areas For Cctv Effectiveness Assessment—The Issue Of Spatially Aggregated Data, Adam Dabrowski, Piotr Matczak, Andrzej Wójtowicz, Michael Leitner

Faculty Publications

Progress in surveillance technology has led to the development of Closed-Circuit Television (CCTV) systems in cities around the world. Cameras are considered instrumental in crime reduction, yet existing research does not unambiguously answer the question whether installing them affects the number of crimes committed. The quasi-experimental method usually applied to evaluate CCTV systems’ effectiveness faces difficulties with data quantity and quality. Data quantity has a bearing on the number of crimes that can be conclusively inferred using the experimental procedure. Data quality affects the level of crime data aggregation. The lack of the exact location of a crime incident in …

Using Deep Learning To Forecast Spatiotemporal Crime Patterns, Shuzhan Fan

LSU Doctoral Dissertations

The distributional patterns of crime occurrences are closely related to their spatial, temporal, and environmental contexts. It has been a hot topic for researchers and crime analysts to discover such complex relationships in order to forecast crime, both spatially and temporally. Many factors play a role in the occurrences of crimes. Conventional crime forecasting research has primarily relied on historical crime records and socioeconomic data, while ignoring the rich social media and other environmental context data. The large volume of data requires a more appropriate forecasting framework with the ability to take in massive multimodal data and possibly achieve better …

Homogenization Of Species Composition And Species Association Networks Are Decoupled, Daijiang Li, Timothée Poisot, Donald M. Waller, Benjamin Baiser

Faculty Publications

© 2018 John Wiley & Sons Ltd Aim: Ecological communities are composed of both species and the biotic relationships (interactions or spatial associations) among them. Biotic homogenization in species composition (i.e., increased site-to-site similarity) is recognized as a common consequence of global change, but less is known about how the similarity of species relationships changes over space and time. Does homogenization of species composition lead to homogenization of species relationships or are the dynamics of species relationships decoupled from changes in species composition?. Location: Wisconsin, USA. Time period: 1950–2012. Major taxa studied: Vascular plants. Methods: We used long-term resurvey data …

Gauging Support For Macroecological Patterns In Helminth Parasites, Tad A. Dallas, A. Alonso Aguirre, Sarah Budischak, Colin Carlson, Vanessa Ezenwa, Barbara Han, Shan Huang, Patrick R. Stephens

© 2018 John Wiley & Sons Ltd Aim: To explore spatial patterns of helminth parasite diversity, and to investigate three main macroecological patterns – (a) latitude–diversity relationships, (b) positive scaling between parasite and host diversity, and (c) species–area relationships – using a largely underutilized global database of helminth parasite occurrence records. Location: Global. Methods: We examined the London Natural History Museum’s collection of helminth parasite occurrence records, consisting of over 18,000 unique host species and 27,000 unique helminth parasite species distributed across over 350 distinct terrestrial and aquatic localities. Results: We find support for latitudinal gradients in parasite diversity and …

Habitat Suitability Estimated By Niche Models Is Largely Unrelated To Species Abundance, Tad A. Dallas, Alan Hastings

Faculty Publications

© 2018 John Wiley & Sons Ltd Aim: Data on species occurrences are far more common than data on species abundances. However, a central goal of large-scale ecology is to understand the spatial distribution of abundance. It has been proposed that species distribution models trained on species occurrence records may capture variation in species abundance. Here, we gauge support for relationships between species abundance and predicted climatic suitability from species distribution models, and relate the slope of this relationship to species traits, evolutionary relationships and sampling completeness. Location: USA. Time period: 1658–2017. Major taxa studied: Mammal and tree species. Methods, …

A Comparison Of Machine Learning Techniques For Taxonomic Classification Of Teeth From The Family Bovidae, Gregory J. Matthews, Juliet K. Brophy, Maxwell Luetkemeier, Hongie Gu, George K. Thiruvathukal

Faculty Publications

This study explores the performance of machine learning algorithms on the classification of fossil teeth in the Family Bovidae. Isolated bovid teeth are typically the most common fossils found in southern Africa and they often constitute the basis for paleoenvironmental reconstructions. Taxonomic identification of fossil bovid teeth, however, is often imprecise and subjective. Using modern teeth with known taxons, machine learning algorithms can be trained to classify fossils. Previous work by Brophy et al. [Quantitative morphological analysis of bovid teeth and implications for paleoenvironmental reconstruction of plovers lake, Gauteng Province, South Africa, J. Archaeol. Sci. 41 (2014), pp. 376–388] uses …

The Urban Archaeological Supersite Paradigm: Integrating Archaeology And Hgis Into Heritage Management, Andrea P. White

LSU Doctoral Dissertations

The archaeological heritages of many of the world’s historic cities are at risk. If these urban archaeological resources are destroyed before excavation and documentation using sound archaeological techniques, the material histories of these cities are erased. The Urban Archaeological Supersite Paradigm is presented as means to address some of the threats facing urban archaeological sites.

The urban archaeological supersite paradigm is both an applied and a scholarly research framework useful for examining and interpreting the urban past and for helping to address urban archaeological heritage at risk. It conceptualizes the historic city as a supersite made up of numerous archaeological …

I Am Complicated, And So Is My Blackness: A Trifecta Exploration Of Educational Spaces And Identity Development, Kala Burrell-Craft

LSU Doctoral Dissertations

Myriads of research studies have been written over the past 20 years highlighting the racial gap and disparities in educational opportunities and outcomes between Black and White students, but as revealed in a review of the literature, more studies need to be conducted that examine the intersection of race, space/place, and racial identity development. Using critical race theory as a framework, this study comprised of three separate, but related essays that explore the function of educational spaces in which Black Americans navigate, grow, and develop as it intersects with race, space/place, and identity development. Essay one is a critical narrative …

Return To The Repressive: Re-Thinking Nature- Culture In Contemporary Feminist Theory, Deborah Goldgaber

Faculty Publications

In "History of Sexuality"(Vol I.) Foucault argued that repression is the wrong model of power, understanding it in exclusively negative terms, as external to the body it constrains and inhibits. Power may also be positive, productive, and constitutive of the body and its possibilities. Thus, an adequate account of the relation between cultural forces and the body, Foucault argues, must challenge the "repressive hypothesis"(RH). Contemporary feminist accounts of the body are structured by this same oppositional view of power Foucault assumed: to call on Rosi Braidotti's distinction, discursive (cultural) forces are either negative or repressive (potestas) or positive and empowering …

This project was carried out in three main phases: (1) development and validation of technologies, (2) education and outreach to students, and (3) outreach to industry consisting …

Citizen Science In 4-H: Youth Volunteer Motivations, Participation, Retention And Scientific Literacy, Veronica Del Bianco

LSU Doctoral Dissertations

The primary purpose of this study was to examine the influence of volunteer motivation, participation, and citizen science project type on the retention and scientific literacy of 4-H youth volunteers ages 8-19 years participating in science projects. The conceptual model of participation in organized activities (OA) proposed by Bohnert, Fredericks and Randall (2010) was used as a framework for the variables included in the study categorizing them as predictors of participation, participation, program characteristics, or outcomes. A systematic review of volunteer motivations, retention, and scientific literacy in citizen science projects exposed that the literature contains silos of information published in …

Natural Resources-Based Conflicts In Coastal Louisiana: A Multi-Faceted Social And Ecological Setting, Audrey Grismore

LSU Doctoral Dissertations

The Louisiana coastal zone supports numerous natural resource-based economies and due to overlapping demands on the same territory, conflicts among users and resource managers have emerged. When the state recognized serious depletion of oysters in the late nineteenth century, it intervened with a set of conservation polices to try to establish sustained yields that produced one set of conflicts. When the oil industry began operating in the coastal estuaries and wetlands in the 1930s, it produced additional conflicts with fishing folk. The zone of conflict gave rise to cyclic adaptations as each group struggled to sustain its environmentally based economic …

Teachers As Leaders: An Autoethnographic Account Into The Way That Personal Spirituality Influenced One Teacher's Leadership In A South Louisiana High School, Scott Mckneely Blanchard

LSU Doctoral Dissertations

The purpose of this autoethnographic study is to better understand the role spiritual leaders have in both educational settings and in the motivation of students. An overarching question guides this autoethnographic study: Is spiritual leadership, influenced by Christianity, an appropriate form of mentoring-leadership relationships in public secondary schools? The specific research sub-questions for this study address the following: 1. How do servant leadership and spiritual leadership help create this autonomous learning environment identified by Deci and therefore reduce the number of amotivated students? 2. How can understanding the student as an individual help a teacher confront the issues with motivation …

Landscapes Of Persistence And Ritual Architecture At The Cosma Complex, Upper Nepeña Valley, Peru., Kimberly Elizabeth Munro

LSU Doctoral Dissertations

This dissertation focuses on the Cosma Complex, a multi-component archaeological site located at the headwaters of the Nepeña River, on the western slopes of the Cordillera Negra in the modern Department of Ancash, Peru. The overarching goal of this study is to understand not only Cosma’s influence as a religious center within the Nepeña Valley and the surrounding region, but its recurring occupation over a 5000-year time span and its role in religious networks within the valley through its function as a cultural landscape resource or persistent place.

The Cosma complex extends over 250 hectares and includes two multi-storied temple …

A Note On The Knot Floer Homology Of Fibered Knots, John A. Baldwin, David Shea Vela-Vick

Faculty Publications

We prove that the knot Floer homology of a fibered knot is nontrivial in its next-to-top Alexander grading. Immediate applications include new proofs of Krcatovich’s result that knots with L–space surgeries are prime and Hedden and Watson’s result that the rank of knot Floer homology detects the trefoil among knots in the 3–sphere. We also generalize the latter result, proving a similar theorem for nullhomologous knots in any 3–manifold. We note that our method of proof inspired Baldwin and Sivek’s recent proof that Khovanov homology detects the trefoil. As part of this work, we also introduce a numerical refinement of …

Three-Dimensional Flow, Morphologic Change, And Sediment Deposition And Distribution Of Actively Evolving Neck Cutoffs Located On The White River, Arkansas, Derek Allen Richards

LSU Doctoral Dissertations

Neck cutoffs are important and prominent features of alluvial rivers yet detailed field-based research of neck cutoffs has been insufficient to fully characterize three-dimensional flow, morphologic change, and sediment deposition and distribution. The main objectives of this research are to examine the formation and evolution of neck cutoffs by characterizing the flow field, morphology, and sediment distribution through neck cutoffs with complex planform configurations located on the White River, Arkansas. Results led to the production of two conceptual models. The flow model has main hydrodynamic characteristics of (1) tight bend flow resulting from flow redirection of nearly 180° through the …

Community Phylogeny Of The Globally Critically Imperiled Pine Rockland Ecosystem, Lauren B. Trotta, Benjamin Baiser, Jennifer Possley, Daijiang Li, James Lange, Sarah Martin, Emily B. Sessa

Faculty Publications

© 2018 Botanical Society of America Premise of the Study: Community phylogenetic methods incorporate information on evolutionary relationships into studies of organismal assemblages. We used a community phylogenetic framework to investigate relationships and biogeographic affinities and to calculate phylogenetic signal of endemism and invasiveness for the flora of the pine rocklands—a globally critically imperiled ecosystem with a significant portion of its distribution in South Florida, United States. Methods: We reconstructed phylogenetic relationships of 538 vascular plant taxa, which represent 92.28% of the vascular flora of the pine rocklands. We estimated phylogenetic signal for endemism and invasiveness using phylogenetic generalized linear …

Measurement And Modeling Of The Spatiotemporal Dynamics Of Beach Surface Moisture Content, Phillip P. Schmutz, Steven L. Namikas

Faculty Publications

The spatiotemporal dynamics of surface moisture exert a significant influence on the operation of aeolian transport systems at many beaches. However, we currently lack the detailed understanding of variability in surface moisture required to incorporate it into aeolian models. This problem is addressed here through direct measurements and simulation modeling of beach surface moisture over a twelve-day period, and through quantification of the relative contributions of evaporation, condensation and groundwater inputs to surface moisture. It was found that the beach surface can be characterized spatially in terms of three moisture zones: a consistently dry zone (40%). The relative influence of …

Isolation By Marine Barriers And Climate Explain Areas Of Endemism In An Island Rodent, Thomas C. Giarla, Sean P. Maher, Anang S. Achmadi, Meagan K. Moore, Mark T. Swanson, Kevin C. Rowe, Jacob A. Esselstyn

Faculty Publications

Aim: The Indonesian island of Sulawesi is home to thousands of endemic terrestrial animal species. Phylogeographical studies of some of these taxa revealed concordant distribution patterns (areas of endemism; AoEs), suggestive of a shared evolutionary or ecological mechanism driving divergence among various terrestrial taxa. Generally, AoEs have been attributed to Pleistocene marine incursions, geological fault zones and Sulawesi's history as an archipelago. We test, for the first time, the hypothesis that population divergences are associated with unsuitable climate spaces at the boundaries between these areas. Location: Sulawesi, Indonesia. Taxon: Maxomys musschenbroekii, a common murid rodent endemic to Sulawesi. Methods: We …

Ants Alter Molecular Characteristics Of Soil Organic Carbon Determined By Pyrolysis-Chromatography/Mass Spectrometry, Zhongsheng Zhang, Zhuo Wei, Jim Jian Wang, Ran Xiao, Yili Meng, Haitao Wu, Xianguo Lyu

Faculty Publications

Colonization by ecosystem engineers, such as ants, have important but occasionally unnoticed roles in regulating soil carbon cycles. However, little information is available pertaining to ant effects on changing molecular features of soil organic matter. In this study, we characterized total soil organic carbon (SOC), total nitrogen, water extractable organic carbon (WEOC) as well as molecular characteristics of humic acids (HAs) of ant mound soils (SoilAnt) and the surrounding soils (SoilCon) using pyrolysis-chromatography/mass (py-GC/MS). SOC, total nitrogen and WEOC contents of SoilAnt were significantly lower than those of SoilCon. SoilAnt samples had significant higher nitrogen containing compounds proportions in pyrolysis …

©2018. The Authors. The Sr and Nd isotopic compositions of siliciclastic sediments and the Nd isotopic compositions of planktonic foraminifera are investigated in sediment trap samples collected in 2015 at water depths of 500 and 2,800 m to (1) track the seasonal changes in the sources and transport patterns of siliciclastic sediments to Benham Rise, (2) constrain the Nd isotopic compositions of the planktonic foraminifera throughout the water column, and (3) assess the influences of lithogenic inputs on the Nd isotopic compositions of the water masses. We demonstrate that volcanic matter and eolian dust are derived primarily from Luzon Island …

Miocene Volcaniclastic Sequence Within The Xiyu Formation From Source To Sink: Implications For Drainage Development And Tectonic Evolution In Eastern Pamir, Nw Tibetan Plateau, Xiaochun Wei, Hongbo Zheng, Ping Wang, Ryuji Tada, Peter D. Clift, Fred Jourdan, Chao Luo, Hanlin Chen

Faculty Publications

©2018. American Geophysical Union. All Rights Reserved. The formation of the Pamir salient and the Tashkorgan-Yarkand River is highly debated with the ages ranging from pre-Cenozoic to late Miocene. One approach to resolve these issues is to draw support from the sedimentary record in the surrounding basins. A volcaniclastic sequence, which divides into Lower and Upper Members, was identified in the southwestern Tarim Basin. The Lower Member was transported by dilute streamflows, which likely flowed during or soon after eruptions, while the Upper Member was formed by a syneruptive volcanic debris flow. Chronological, petrologic, and geochemical data consistently indicate that …
