The Fate Of Atmospherically Deposited Mercury In Mountain Lake Food Webs, And Implications For Fisheries Management, Ariana Martos Chiapella

Dissertations and Theses

Mountain lakes are an iconic feature of the landscape in the Mountain West. They hold significant ecological and cultural value, and are important sentinels of environmental change. Despite their pristine image, these remote waterbodies are subjected to numerous anthropogenic stressors. Mountain lakes are naturally fishless systems, but historical fish stocking has led to major changes in mountain lake food web structure, including declines of resident amphibians, large-bodied zooplankton, and emergent insect populations. Atmospherically deposited contaminants, such as mercury, can accumulate in mountain lake food webs, leading to relatively high levels in the fish relative to the water. Managing for these …

Architectural And Philosophical 'Makerspace' Redesign Impact On Teacher Beliefs And Practices: A Case Study, Rurik-Rory James Nackerud

Dissertations and Theses

Current jobs in a global economy require more complex cognitive skills, such as critical thinking, cooperation, creativity, and collaboration, in addition to content knowledge. To address these areas, researchers have suggested the use of a 'makerspace' in schools. As with many other establishments, my school remodeled the primary school to create a makerspace for developing these skills. What impact might a makerspace -- a physical as well as a curricular change -- have on teachers' individual and collaborative learning? The purpose of this case study was to describe how the makerspace concept and changes to classroom or instructional space influence …

Variations In Implementation Of Specifications Grading In Stem Courses, Mai Yin Tsoi, Mary E. Anzovino, Amy H. Lin Erickson, Edward R. Forringer, Emily Henary, Angela Lively, Michael S. Morton, Karen Perell-Gerson, Stan Perrine, Omar Villanueva, Marygeorge Whitney, Cynthia M. Woodbridge

Georgia Journal of Science

Specifications grading is an assessment strategy based on mastery learning, clear learning objectives, and frequent evaluations and feedback. Twelve instructors at a southeastern four-year public college implemented the specifications grading method across eight discrete courses in four STEM areas. In this modified assessment strategy, the students controlled their grades through multiple attempts, with limitations, on assessments of course objectives. The instructors designed and executed specifications grading in unique ways that aligned with their content areas, teaching beliefs, and individual teaching styles.

Preliminary observations suggest that, regardless of subject area, specifications grading can be used as an alternative to traditional assessment …

Turtles Of The Early Pleistocene Santa Fe River 1b Locality, Dennis Parmley, Robert Chandler, Linda Chandler

Georgia Journal of Science

The early Pleistocene (ca. 2.588–1.806 Ma) Santa Fe River 1B fossil site (SF1B) of Gilchrist County, Florida has yielded turtle fossils representing nine genera and at least 10 species. Of these, at least six genera are aquatic turtles (Macrochelys and/or Chelydra, Apalone, Trachemys, Pseudemys, Sternotherus, and Kinosternon) and three are terrestrial (Hesperotestudo, Gopherus, and Terrapene). Hesperotestudo and an undescribed cf. Trachemys are the only extinct turtles identified in the paleoherpetofauna. Overall, the generic composition of the turtle fauna is predominantly modern and indicative of the southeastern United States today.

Polycystic Kidney Disease, Caitlin Byrne

Nursing Student Class Projects (Formerly MSN)

Abstract

Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are two forms of polycystic kidney disease (PKD) and are leading causes of end stage renal disease (Silverman, 2015). PKD can affect both children and adults and is one of the most common hereditary disorders (Silverman, 2015). A mutation on the genes PKD-1 and PKD-2 and the encoding proteins polycystin-1 and polycystin-2 is the pathophysiology behind development of PKD (Silverman, 2015). Genetic testing, renal ultrasounds, CT scans and MRI’s can all be used to help diagnosis PKD (Silverman, 2015). PKD can cause other medical complications like …

Parental Support, Sibling Influences And Family Dynamics Across The Development Of Canadian Interuniversity Student-Athletes, Georgia I. Lundy, Veronica Allan, Ian Cowburn, Jean Cote

Journal of Athlete Development and Experience

A vast body of research focuses on the role of parents in athlete development; however, little is known about developmental influences of siblings. In general, family dynamics (i.e., patterns of relating or interacting among family members) have yet to be investigated in youth sport contexts. This study examines how family dynamics and the individual roles of parents and siblings influence the development of Canadian interuniversity student-athletes over time. Participants included four male and six female student-athletes. Each participant took part in a qualitative retrospective timeline interview. All data was subjected to a thematic analysis. Results indicate that siblings and parents …

Modeling Irrigation Behavior In Groundwater Systems, Timothy Foster, Nicholas Brozovic, Adrian P. Butler

Daugherty Water for Food Global Institute: Faculty Publications

Integrated hydro-economic models have been widely applied to water management problems in regions of intensive groundwater-fed irrigation. However, policy interpretations may be limited as most existing models do not explicitly consider two important aspects of observed irrigation decision making, namely the limits on instantaneous irrigation rates imposed by well yield and the intraseasonal structure of irrigation planning. We develop a new modeling approach for determining irrigation demand that is based on observed farmer behavior and captures the impacts on production and water use of both well yield and climate. Through a case study of irrigated corn production in the Texas …

Organic-Inorganic Hybrid Composites: Superhydrophobic Polymer Coatings With Photoreactive Perfluorinated Phthalocyanines, Abdul Azeez

Seton Hall University Dissertations and Theses (ETDs)

ABSTRACT

We report partly fluorinated and silicon-based polymers that incorporate inorganic/organic materials capable of generating reactive oxygen species (ROS) using only visible light and air. Polyvinylidene fluoride (PVDF), which incorporated a known perfluorinated phthalocyanine photosensitizer, F₆₄PcZn, supported on silicon and titanium oxides was further modified via chemical surface roughening to exhibit enhanced hydrophobicity when used as a coating. Water contact angles as high as ~159° have been observed, vs. ~ 92° for the unmodified polymer. The polymer matrix, however, does not resist the ROS it produces as evidenced by spectroscopic and SEM data. A polysiloxane matrix was similarly …

Testing Newton/Gr, Mond And Quantised Inertia On Wide Binaries, Me Mcculloch, Jh Lucio

School of Biological and Marine Sciences

Wide binary stars are within the low-acceleration regime in which galactic rotation curves deviate from Newtonian or general relativistic predictions. It has recently been observed that their rotation rates are similarly anomalous in a way that dark matter cannot explain, since it must be smooth on these small scales to fit galaxy rotation curves. Here, it is shown that Newtonian/GR models cannot predict these wide binaries since dark matter cannot be applied. It is also shown that MoND cannot predict these systems. However, a model which assumes that inertia is due to Unruh radiation made inhomogeneous in space by relativistic …

Prediction Of Hierarchical Classification Of Transposable Elements Using Machine Learning Techniques, Manisha Panta

LSU New Orleans Theses and Dissertations

Transposable Elements (TEs) or jumping genes are the DNA sequences that have an intrinsic capability to move within a host genome from one genomic location to another. Studies show that the presence of a TE within or adjacent to a functional gene may alter its expression. TEs can also cause an increase in the rate of mutation and can even promote gross genetic arrangements. Thus, the proper classification of the identified jumping genes is important to understand their genetic and evolutionary effects. While computational methods have been developed that perform either binary classification or multi-label classification of TEs, few studies …

Associations Between Community Violence Exposure, Emotional Desensitization, And Internalizing And Externalizing Symptoms: The Influence Of Route Of Exposure And Interpersonal Proximity To The Victims Of Violence, Megan M. Zeringue

LSU New Orleans Theses and Dissertations

The current study examines associations between community violence exposure (CVE) and internalizing and externalizing symptoms. The emotional desensitization hypothesis states that moderate levels of CVE will be associated with increased internalizing symptoms, whereas high levels of CVE will be associated with decreases in internalizing distress. The current study extends prior research by examining whether patterns of emotional desensitization differ based on the route of exposure – either being personally victimized or witnessing community violence. Further, associations examined the influence of interpersonal proximity to the victims of violence – that is, whether individuals are victims themselves (most proximal), witness violence against …

A Novel Role Of Hrr25 In Cell Wall Integrity Maintenance And Functional Analysis Of Hrr25 Domains, Amita Bhattarai

LSU New Orleans Theses and Dissertations

Hrr25 is a highly conserved serine/threonine protein kinase with diverse functions and it localizes to a number of intracellular sites. Hrr25 possesses an N-terminal kinase domain, a middle region, and a C-terminal proline/glutamine rich domain. In this thesis, we systematically characterized the roles of these three domains of Hrr25 on cell growth, cell morphology, and its cellular localizations. Additionally, we identified a novel target of Hrr25, Pin4. We show that Hrr25-dependent phosphorylation of Pin4 is required for cell wall integrity maintenance. We found that that Hrr25 and Pin4 physically interact in vivo and that the C-terminal domain of Hrr25 is …

Sicilian Roots: How The Agricultural Pursuits Of Immigrant Sicilians Shaped Modern New Orleans Cuisine, Laura A. Guccione

LSU New Orleans Theses and Dissertations

The influx of immigrant Sicilians into southeastern Louisiana in the nineteenth century resulted in a parallel rise of the French Quarter as a culinary destination. Through an analysis of menus, recipe books, city directories, newspapers and census rolls, this work maps the growing influence of Sicilian farmers, vendors, and restaurateurs on New Orleans foodways. The often-overlooked community of Sicilians already living in the city in the early nineteenth century set the stage for the mass migration from Sicily to New Orleans later in the century, when Sicilians gained control of the produce food market in southeast Louisiana. A comparison of …

Effective Statistical Energy Function Based Protein Un/Structure Prediction, Avdesh Mishra

LSU New Orleans Theses and Dissertations

Proteins are an important component of living organisms, composed of one or more polypeptide chains, each containing hundreds or even thousands of amino acids of 20 standard types. The structure of a protein from the sequence determines crucial functions of proteins such as initiating metabolic reactions, DNA replication, cell signaling, and transporting molecules. In the past, proteins were considered to always have a well-defined stable shape (structured proteins), however, it has recently been shown that there exist intrinsically disordered proteins (IDPs), which lack a fixed or ordered 3D structure, have dynamic characteristics and therefore, exist in multiple states. Based on …

Iron-Sulfur Cluster Assembly; In Vivo Analysis Of The Methanogenic Suf System, Evan Dunkle

LSU Master's Theses

Iron-sulfur (Fe-S) clusters are among the most ancient and prevalent of all biological cofactors. Their assembly into associated proteins is a tightly regulated process with many organisms employing multiple cluster assembly pathways. Much is known about Fe-S cluster assembly in aerobic organisms such as Escherichia coli (E. coli) but little is known in regards to cluster assembly in more ancient organisms such as methanogens. Methanogens are members of the domain of Archaea and are defined by their ability to generate methane as a byproduct of their main energy generating pathway. Methanogens also have significantly higher Fe-S cluster content …

General Nonlinear-Material Elasticity In Classical One-Dimensional Solid Mechanics, Ronald Joseph Giardina Jr

LSU New Orleans Theses and Dissertations

We will create a class of generalized ellipses and explore their ability to define a distance on a space and generate continuous, periodic functions. Connections between these continuous, periodic functions and the generalizations of trigonometric functions known in the literature shall be established along with connections between these generalized ellipses and some spectrahedral projections onto the plane, more specifically the well-known multifocal ellipses. The superellipse, or Lam\'{e} curve, will be a special case of the generalized ellipse. Applications of these generalized ellipses shall be explored with regards to some one-dimensional systems of classical mechanics. We will adopt the Ramberg-Osgood relation …

Epistasis In Alzheimer’S Disease: Interactions Between Clu-Ms4a4e And Wwc1-Tln2, Omoremi Hamblin

Undergraduate Honors Theses

Alzheimer’s disease is the most common form of dementia among people age 65 and older. Because of the complexity of this disease, many studies have taken the epistatic approach to discover underlying genetic disorders. Epistasis is the study of gene-gene interaction in which the effects of one gene mask the effects of the other gene. In this study, we attempted to replicate two earlier studies that identified three gene-gene interactions. We used the 2019 Alzheimer’s Diseases Genetics Consortium (ADGC) dataset and we conducted a logistic regression with and without the interaction terms. The interactions we considered were between CLU rs11136000 …

Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers

Biology Theses

Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …
