Finding The Resilient Teacher Within: A Workshop To Address K-12 Teacher Well-Being, Laura Jones

Educational Specialist, 2009-2019

Teacher stress comes from a variety of sources: accountability pressures, lack of time to relax, students who are not motivated, excessive duties and responsibilities that go beyond the classroom, testing pressure, large class size, lack of administrative support, and general concern for the safety and well being of their students (Richards, 2012). As a result of the constant high stress, more teachers are reporting mental/physical health issues and leaving the profession (Richards, 2012). One way to help deal with the stress teachers are feeling is to strengthen the teacher from within by using the resources they have already. This paper …

Rat Hind Limb Nociceptive Withdrawal Response Depends On Initial Paw Position But Not Stimulus Location, Kimberly Seamon

Senior Honors Projects, 2010-2019

There have been numerous studies in non-human animals on the effect of stimulus location on the NWR and at least a few studies that address the role of initial posture. However, all of these studies were conducted in anesthetized, decerebrated, or spinalized mammals. Since descending modulation and long loop reflexes may influence the NWR, the anesthetized spinalized/decerebrated animal may not be an adequate model of normal animals. Therefore, the primary aim of this study was to determine the effect of the stimulus location and initial paw position on the direction and magnitude of the nociceptive withdrawal response to heat stimulus …

Ability Of Skin Bacteria On The Panamanian Frog Species, Craugastor Fitzingeri, To Inhibit The Fungal Pathogen Batrachochytrium Dendrobatidis, Tiffany N. Bridges

Senior Honors Projects, 2010-2019

An emerging infectious disease caused by the fungus Batrachochytrium dendrobatidis (Bd) is leading to global amphibian declines and is threatening the biodiversity of amphibians. Bd susceptibility varies among individuals, species, and populations perhaps due to defensive mechanisms such as symbiotic skin microbes. Some species of amphibians such as Craugastor fitzingeri, a terrestrial frog native to Central America, continue to persist in Bd-positive environments in Panama. My study focused on identifying antifungal bacterial isolates and determining the culturability of the bacterial community on 15 individuals of C. fitzingeri. Morphologically distinct isolates were challenged against Bd in …

Pattern Discovery In Dna Using Stochastic Automata, Shweta Shweta

Master's Projects

We consider the problem of identifying similarities between different species of DNA. To do this we infer a stochastic finite automata from a given training data and compare it with a test data. The training and test data consist of DNA sequence of different species. Our method first identifies sentences in DNA. To identify sentences we read DNA sequence one character at a time, 3 characters form a codon and codons form proteins (also known as amino acid chains).Each amino acid in proteins belongs to a group. In total we have 5 groups’ polar, non-polar, acidic, basic and stop codons. …

Sunyata In The West, David Grandy

Comparative Philosophy

I argue that sunyata, or something like it, manifested itself in early Western thought. While Plato and Aristotle resisted emptiness or nothingness, they nevertheless felt themselves obliged to venture close to its edge in order to ground their explanations of changing reality to unchanging principles. These principles (Plato’s receptacle and Aristotle’s prime matter) embody much of the indeterminancy long associated with the Mahayana understanding of sunyata. Although their function was to enable lasting (static) explanations of reality by putting change out of play, they themselves shade off toward a featureless being evocative of non-being. Moving along a somewhat …

Transformational Learning: An Investigation Of The Emotional Maturation Advancement In Learners Aged 50 And Older, Susan Lorraine Lundry

Dissertations

Human beings have spent much time and effort in trying to understand themselves, others, and their world. Mankind uses intellect when trying to understand life but the majority of people continue to encounter frustration, confusion, and a variety of obstacles when dealing with daily challenges and people. Theorists and researchers understand that successful existence requires more than mere knowledge; it requires a level of understanding, a form of wisdom foreign to the bulk of the populace. The missing ingredient for this kind of wisdom is the ability to ‘know thyself,’ which is the beginning of establishing a higher level of …

Police Contacts And Attitudes Toward Police: A Study Of Race And Policing, Gary Portway

Honors Program Theses and Projects

The way in which police officers engage with general society is often under meticulous watch by countless amounts of citizens. The United States – at an unprecedented point in regards to technological advancement and education – expedites such meticulous watch in a way that it often becomes noticeable criticism. Strategies of policing such as New York City’s “stop-and-frisk” policy have ignited much criticism of police, and have caused the need for many general improvements to the way in which police facilitate. Since the structure of policing often shifts based on changes within general society, it has become a common standard …

Optimizing A Game Of Chinese Checkers, Nicholas Fonseca

Honors Program Theses and Projects

Chinese Checkers is a multi-player strategy game in which game play can become surprising complex as the game progresses. In spite of this game's complexity, questions involving games with multiple players have received little research attention. This paper considers the three player case and discusses how to describe short games. By utilizing these tendencies for short games, a heuristic function can be defined which associates a player's possible move with a heuristic value. These heuristic values guide a search algorithm which searches through all the possible moves made in a game. To guide this discussion for three player games, the …

A Critical Analysis Of Random Response Techniques, Emanuel Zanzerkia

Honors Program Theses and Projects

In order to understand and make informed decision on sensitive topics such as domestic violence and drug use, interviews have been used to collect data. However it is difficult to assess how truthful respondents are since they may not feel at ease revealing the truth to an interviewer. Surveyors of sensitive issues face the problem that respondents may be reluctant to answer truthfully since the respondent may feel pressured socially or may fear the repercussions of their truthful answer. Processes known as random response techniques have been introduced to allow interviewers the ability to extract information they need for a …

Digital Lessons For Enhancing Communicative Skills: A Handbook For Turkish Efl Teachers, Hale H. Demirel

Master's Projects and Capstones

It is necessary for English teachers who are interested in exposing their students to the authentic and communicative use of English to have access to model instructional materials. This project sought to develop a handbook and an accompanying website for teachers of English working with intermediate ESL/EFL students at university level. The handbook includes two theme-based lessons that emphasize the development of communicative competence with the help of engaging free digital tools. The content of the handbook can be improvised or modified and adapted to meet the needs of unique teaching-learning situations in case of need.

Monitoring Biodiversity Of San Francisco Peninsula Grasslands Using Lepidoptera As A Bioindicator, Jonathan B. Sifuentes-Winter

Master's Projects and Capstones

San Francisco Peninsula grasslands have seen an influx of non-native invasive species starting in the 1500’s, threatening ecological stability by reducing biological diversity. To combat these invasive species, multiple public agencies have begun to adopt an integrated pest management (IPM) approach. This ecologically-based approach to pest management utilizes three controversial techniques, which are presently used or are under consideration for use on the San Francisco Peninsula: herbicide application, conservation grazing, and prescribed fire. In this paper, I will evaluate the use of the taxa Lepidoptera as a bioindicator of biodiversity to assess the environmental impacts of these techniques. The application …

Towards A Theory Of Recursive Function Complexity: Sigma Matrices And Inverse Complexity Measures, Bradford M. Fournier

LSU New Orleans Theses and Dissertations

This paper develops a data structure based on preimage sets of functions on a finite set. This structure, called the sigma matrix, is shown to be particularly well-suited for exploring the structural characteristics of recursive functions relevant to investigations of complexity. The matrix is easy to compute by hand, defined for any finite function, reflects intrinsic properties of its generating function, and the map taking functions to sigma matrices admits a simple polynomial-time algorithm . Finally, we develop a flexible measure of preimage complexity using the aforementioned matrix. This measure naturally partitions all functions on a finite set by characteristics …

Computation Of A Virtual Tide Corrector To Support Vertical Adjustment Of Autonomous Underwater Vehicle Multibeam Sonar Data, Lawrence H. Haselmaier

LSU New Orleans Theses and Dissertations

One challenge for Autonomous Underwater Vehicle (AUV) multibeam surveying is the limited ability to assess internal vertical agreement rapidly and reliably. Applying an external ellipsoid reference to AUV multibeam data would allow for field comparisons. A method is established to merge ellipsoid height (EH) data collected by a surface vessel in close proximity to the AUV. The method is demonstrated over multiple collection missions in two separate areas. Virtual tide corrector values are derived using EH data collected by a boat and a measured ellipsoid to chart datum separation distance. Those values are compared to measurements by a traditional tide …

Arsenic, Cadmium, Copper, And Zinc Levels In Crayfish From Southwest Louisiana And Atchafalaya Basin, E. Gerald Hebert

LSU New Orleans Theses and Dissertations

Heavy metal contamination in food is a worldwide concern. Man-made ponds are domestic sites in the production of Procambarus clarkii and Procambarus zonangulus, two edible species of crayfish. Ponds may be constructed in former sugar cane or rice fields. Crayfish farming is an ancillary seasonal business within the rice-growing season. The use of products to control insects, pests, and weeds in rice and sugar cane production, may cause an accumulation of heavy metals in the crayfish tail within pond structures. Arsenic, cadmium, copper, and zinc are heavy metals that are absorbed through the roots of and distributed through rice products. …

A Desert In Disguise: The Resilience Of The Nebraska Sandhills, Jeff Hartman

School of Natural Resources: Dissertations, Theses, and Student Research

The Nebraska Sandhills are the largest sand dune system in the Western Hemisphere, and are unique because they remain relatively undisturbed from row crop agriculture. Research in the past two decades demonstrated that the Sandhills are dynamic on millennial timescales, switching between stabilized, vegetated states to non-vegetated, mobilized states. The Sandhills are currently stabilized, but understanding how ecological processes are altered as sand dunes transition from stabilized to mobilized states, provides insight into the thresholds, stability, and resilience of this grassland ecosystem. My research investigated the impacts of vegetation disturbances on ecological processes and the sand dune surface stability. For …

Phosphorus Release Potential Of Agricultural Soils Of The United States, Rebecca A. Young

School of Natural Resources: Dissertations, Theses, and Student Research

Phosphorus (P) is one of the leading causes of surface water quality decline in the United States, leading to algal blooms and hypoxia in lakes and streams. Decreasing conservation funds dictate that agencies such as the Natural Resources Conservation Service, maximizes its effectiveness and efficiency in implementing practices to address P management and runoff on agricultural lands. Additional information on P behavior in soil is needed to improve P management plans to reduce pollution risk at the watershed, farm, and field scales. This research focuses on the development of total soil P release models, to be included into assessment and …

The Gender Imbalance In U.S. Outbound Study Abroad: A Case Study Of Semester At Sea, Jessica L. Ryan

Capstone Collection

The purpose of this study is to explore the phenomenon of female college students studying abroad with Semester at Sea (SAS) at twice the rate of their male peers, in the hope of better understanding the significant gender imbalance overall in U.S. outbound study abroad. To put this issue into context, this study uses the theoretical framework of Deci and Ryan’s (1985) Self-Determination Theory of Motivation. Data was analyzed through the lens of intrinsic verses extrinsic motivation to answer the guiding research question: Is there a difference between male and female college students in their motivations to study abroad and, …

College Students' Knowledge About Stuttering: A Preliminary Investigation, Nichole Marie Terry

Student Theses and Dissertations

There is ample research on the public’s perception of individuals who stutter, but little research was found about the public’s knowledge about the definition and etiology of stuttering. The present study attempted to address whether college students in a specific area of study possessed either quantitative or qualitative differences in their knowledge about the definition and etiology of stuttering. Subjects included 80 males and 100 females across 9 different academic colleges to assess their knowledge of stuttering. Five open response questions were presented to each participant. Responses were orthographically transcribed and coded based on the current notions on the etiology …

Extracting Windows Event Logs Using Memory Forensics, Matthew Veca

LSU New Orleans Theses and Dissertations

Abstract Microsoft’s Windows Operating System provides a logging service that collects, filters and stores event messages from the kernel and applications into log files (.evt and .evtx). Volatility, the leading open source advanced memory forensic suite, currently allows users to extract these events from memory dumps of Windows XP and Windows 2003 machines. Currently there is no support for users to extract the event logs (.evtx) from Windows Vista, Win7 or Win8 memory dumps, and Volatility users have to rely on outside software in order to do this. This thesis discusses a newly developed evtxlogs.py plugin for Volatility, which allows …

Characterizing Far-Infrared Laser Emissions And The Measurement Of Their Frequencies, Michael Jackson, Lyndon R. Zink

All Faculty Scholarship for the College of the Sciences

The generation and subsequent measurement of far-infrared radiation has found numerous applications in high-resolution spectroscopy, radioastronomy, and Terahertz imaging. For about 45 years, the generation of coherent, far-infrared radiation has been accomplished using the optically pumped molecular laser. Once far-infrared laser radiation is detected, the frequencies of these laser emissions are measured using a three-laser heterodyne technique. With this technique, the unknown frequency from the optically pumped molecular laser is mixed with the difference frequency between two stabilized, infrared reference frequencies. These reference frequencies are generated by independent carbon dioxide lasers, each stabilized using the fluorescence signal from an external, …

Speedups And Orbit Equivalence Of Finite Extensions Of Ergodic Zᵈ-Actions, Aimee S.A. Johnson, D. M. Mcclendon

Mathematics & Statistics Faculty Works

We classify n-point extensions of ergodic Zᵈ-actions up to relative orbit equivalence and establish criteria under which one n-point extension of an ergodic Zᵈ-action can be sped up to be relatively isomorphic to an n-point extension of another ergodic Zᵈ-action. Both results are characterized in terms of an algebraic object associated to each n-point extension which is a conjugacy class of subgroups of the symmetric group on n elements.

Classification Of Breast Cancer Patients Using Somatic Mutation Profiles And Machine Learning Approaches, Suleyman Vural

Theses & Dissertations

The high degree of heterogeneity observed in breast cancers makes it very difficult to classify cancer patients into distinct clinical subgroups and consequently limits the ability to devise effective therapeutic strategies. In this study, we explore the use of gene mutation profiles to classify, characterize and predict the subgroups of breast cancers. We analyzed the whole exome sequencing data from 358 ethnically similar breast cancer patients in The Cancer Genome Atlas (TCGA) project. Identified somatic and non-synonymous single nucleotide variants were assigned a quantitative score (C-score) that represents the extent of negative impact on the function of the gene. Using …

A Simulation Of The Mississippi River Salt Wedge Estuary Using A Three-Dimensional Cartesian Z Coordinate Model, Steven K. Ayres

LSU New Orleans Theses and Dissertations

The stratified flow of the lower Mississippi River due to density gradients is a well documented phenomenon. This stratification of fresh and saline water manifests itself as a heavier wedge of saline water that extends upriver and a buoyant fresh water plume extending into the Gulf of Mexico past the Southwest Pass jetties. The maximum absolute distance of saltwater intrusion observed anywhere in the world occurred on the Mississippi River in 1939 and 1940 when saltwater was observed approximately 225 km upstream from the mouth of Southwest Pass. The U. S. Army Corps of Engineers now prevents the wedge from …

Submarine Channel Evolution Linked To Rising Salt Dome, Mississippi Canyon, Gulf Of Mexico, Rachel C. Carter

LSU New Orleans Theses and Dissertations

By examining halokinetics and channel evolution in a deep-water system, we investigate how submarine channel morphology is affected by changing seascape linked to diapirism. The study area is located in Mississippi Canyon, Gulf of Mexico (GOM), situated directly off the continental slope in a prominent salt dome region. Interactions of salt domes with submarine channels in the GOM are poorly documented. Utilizing 3D seismic data and seismic geomorphology techniques, a long-lived Plio-Pleistocene submarine channel system has been investigated to develop a relationship between variable phases of salt movement and plan-form morphology of preserved channels.

We suggest that halokinetics acts as …
