Development And Functional Characterization Of Carbon Nanodot-Peptide Conjugates For The Treatment Of Bone Disease, Abigail Ali
Development And Functional Characterization Of Carbon Nanodot-Peptide Conjugates For The Treatment Of Bone Disease, Abigail Ali
Honors Theses
Carbon nanodots (CDs) synthesized from carbon nanopowder under acid oxidative conditions have unique bone-bind properties that could be exploited for theranostic purposes. In the zebrafish vertebrate model system, CDs bind to bone with high affinity and specificity, they don’t appear to bind to other tissues and they do not affect the bone physiology or animal viability. Thus, carbon-derived CDs could be developed for the delivery of pharmacological agents to bones to treat diseases such as osteoporosis. Biologicals such as peptides, proteins and antibodies are a new and exciting class of pharmacological agents that have been successfully used in treating complex …
The Ripple Effects Of Belonging: How Faculty–Student Connections May Drive Mutual Success, Marissa Burton
The Ripple Effects Of Belonging: How Faculty–Student Connections May Drive Mutual Success, Marissa Burton
Honors Theses
Experiencing a sense of belonging on a college campus is predicted to increase academic success, classroom engagement, and greater well-being for students. Less central to the belonging conversation is faculty belonging; since faculty play an instrumental role in the development of student belonging, we hypothesize that faculty belonging may increase positive student outcomes inside and outside the classroom. Study 1 examines faculty experiences of and beliefs about belonging at a Predominantly White Institution (PWI), with the aim of identifying patterns and indicators of heterogeneity. Results revealed that significant burnout is central to a lack of faculty belonging and stronger desires …
Loneliness By Choice Or By Circumstance?: Examining The Relationship Between Friendship, Need To Belong, And Loneliness, Yuting Hong
Honors Theses
A sense of belonging is a fundamental human need (Baumeister & Leary, 1995; Maslow, 1943). On college campuses, students’ need to belong is often satisfied by interactions with peers. Friends comprise the largest component of college students’ social network, and good friendships provide a variety of resources, such as companionship, help, and emotional security. When students lack high-quality friendships, they are more likely to experience feelings of loneliness. However, there are likely important individual differences in the relationship between friendship quality and loneliness. The cognitive discrepancy theory of loneliness suggests that loneliness arises when there is a gap between the …
A Cross-Taxa Comparison Of Avian Telomere Dynamics, Age, And Lifespan, Benjamin Konigsberg
A Cross-Taxa Comparison Of Avian Telomere Dynamics, Age, And Lifespan, Benjamin Konigsberg
Honors Theses
When eukaryotes replicate cells throughout their life, the end regions of chromosomes naturally degrade as a result of the 5' to 3' directionality of DNA polymerase. There is a point when the chromosome is too damaged to provide normal cellular functions, so the cell will die. Telomeres act as a buffer by providing repetitive sequences of non-coding nucleotides. While telomeres do shorten during replication events, the enzyme telomerase can extend telomeres to prevent senescence. Telomere lengths vary between individuals based on different stressor and stress mitigation. Telomeric rate of change is a metric that can capture telomerase activity by measuring …
Isolation And Identification Of Active Antimicrobial Compounds In Alcaligenes And Chromobacterium Strains, Hannah Lwin
Isolation And Identification Of Active Antimicrobial Compounds In Alcaligenes And Chromobacterium Strains, Hannah Lwin
Honors Theses
ESKAPE pathogens comprise six bacteria that can be highly virulent and are likely to develop antibiotic resistance to many of the currently available antibiotics. New antibiotics are needed to combat these pathogens. Our approach was to isolate and identify antimicrobial compounds from bacteria isolated from soil. Two isolates demonstrating antimicrobial activity were identified as Chromobacterium sp. and Alcaligenes parafaecalis. Preliminary extraction of their antimicrobials was performed.
Engaging Scientific Sense-Making: An Analysis Of Participation Within Informal Science Interaction, Spencer Barbier
Engaging Scientific Sense-Making: An Analysis Of Participation Within Informal Science Interaction, Spencer Barbier
Honors Theses
While science learning in formal educational settings has been extensively examined using frameworks such as Bloom’s Taxonomy, its application to informal science educational environments remains underexplored. Informal science education—occurring outside traditional classrooms—presents unique challenges for evaluation due to its unstructured nature and diverse audiences. This action research study aimed to address this gap by developing and testing a framework that categorizes learner responses into high-order and low-order answers, based on Bloom’s six cognitive domains. The study was conducted at the Hattiesburg Zoo, where a docent volunteer presented two separate docent boxes, or mini science lessons, to members of the public. …

The Effect Of The Black Ink Red Ink Testing Method On Anxiety Levels, Test Performance, And Note-Taking Behavior Among College Students, Peyton Murphy
Honors Theses
Anxiety among students has emerged as a pressing concern due to its significant impact on academic performance and mental well-being (Chen, 2004; Davis, DiStefano, & Schutz, 2008) and is particularly evident in student performance within STEM-related courses (Magula, 2019; Vakili & Pourrazavy, 2017). Previous research has explored various factors influencing test anxiety, including testing methods. The present study examined a testing method called "Black Ink Red Ink" (BIRI), proposed by Rodgers and Rodgers (2011). The effects of the BIRI method were examined on (1) test anxiety, (2) test scores, and (3) note taking motivation and behaviors. Thirty-eight students in a …
Transcendental Blooms: Margaret Fuller And The Radical Language Of Flowers, Jenna Mcclain
Transcendental Blooms: Margaret Fuller And The Radical Language Of Flowers, Jenna Mcclain
Honors Theses
Situated between the literary periods of American Romanticism and Transcendentalism, Margaret Fuller’s writings vary in their topic and medium, offering a unique fusion of literary style as well as a refined yet radical social perspective. Fuller’s work frequently employs flowers as tools for communication rather than as mere symbols, with flowers acting as transmitters of Fuller’s philosophical message in her many sketches and poems. In “The Magnolia of Lake Pontchartrain,” one of her most famous prose sketches, Fuller explores flowers in a nuanced way that exemplifies how floral representations function more like characters than objects in her work. While scholars …
The Factors That Affect Usm Student Experience In The General Chemistry Classroom, Emma Dickerson
The Factors That Affect Usm Student Experience In The General Chemistry Classroom, Emma Dickerson
Honors Theses
Chemistry has a reputation for being a challenging discipline for many students. Enrollment in chemistry courses is much lower than that of other disciplines due to “chemophobia”, which can be caused by many aspects of chemistry.1-2To increase enrollment in chemistry, it is important to understand how to improve the student experience in the classroom. To determine the factors that affect a student’s experience in their current chemistry class, the Chemistry Attitudes and Experiences Questionnaire (CAEQ) was adapted and given to students in General Chemistry I and II classes at The University of Southern Mississippi. Descriptive statistics, an Analysis …
The Sexual Assault Survivor Experience Of Medical Forensic Examinations, Brielle Simonsen
The Sexual Assault Survivor Experience Of Medical Forensic Examinations, Brielle Simonsen
Honors Theses
Following a sexual assault, survivors may seek medical forensic examinations (MFEs) at hospitals. MFEs can be important in identifying and prosecuting the assailant and in receiving necessary physical and psychological care, yet many survivors choose not to undergo the examination. In this qualitative study, I explored survivor experiences of MFEs at United States hospitals to identify possible areas for improvement of the MFE experience. Understanding these experiences is essential to reducing barriers to care, minimizing further harm, and supporting survivor recovery.
Comparing Urban And Rural Mississippi Residents’ Health Literacy Of Sexually Transmitted Infections, Leah Tucker
Comparing Urban And Rural Mississippi Residents’ Health Literacy Of Sexually Transmitted Infections, Leah Tucker
Honors Theses
Health literacy is an individual’s ability to understand medical information to make decisions regarding their health, and it has become an important topic of discussion in the medical field. This is because people with low health literacy are more likely to be in poor health. There have been several programs aimed at improving health literacy across the US, but health literacy varies geographically. Typically, urban areas have higher health literacy rates than rural areas since rural areas have less access to health resources and health care. Almost 80% of Mississippi’s counties are considered rural, and Mississippi has some of the …
Forensic Search Methods: Comparing Effectiveness And Efficiency In A Grassland Environment, Robert Brown
Forensic Search Methods: Comparing Effectiveness And Efficiency In A Grassland Environment, Robert Brown
Honors Theses
An important aspect of death investigations is the recovery of human remains to determine crucial details such as body identity, time of death, and cause of death. Physical evidence is often moved by elements, such as water, gravity, plants, and scavengers in outdoor crime scenes, making recovery challenging. As a result, forensic scientists have created several search methods to locate dispersed human remains. Previous studies have primarily focused on predicting animal scavenging patterns, but few have compared the performance of forensic search methods in specific environments. This study addresses this area of research by assessing three common search methods in …

Women’S Independence In The Archives: A Study Of The Sisters Of The Holy Family As Found In The New Orleans Archdiocese Archive, Georgia Campbell
Honors Theses
The Sisters of the Holy Family, a Catholic convent based in New Orleans, have a space in the archival records of the archdiocese. The overwhelming presence of documents by men means that the story in the archive belongs as much to them as it does to the sisters. This follows the patriarchal hierarchy of the Church. Nevertheless, the documents that are available tell the sisters’ story and how they sought independence

Impact Of Invasive Pine Trees And Their Ectomycorrhizal Fungi Symbionts Upon The Properties And Functions Of Soils In Southern Hemisphere Eucalyptus Forests, Jack T. Baker
Honors Theses
P. radiata trees are invading Southern Hemisphere Eucalyptus forests within New Zealand and southeastern Australia, resulting in a novel codominant forest system. This codominant invasion is unique relative to other pine invasions throughout the Southern Hemisphere. Ectomycorrhizal fungi (EMF) play an important role in all pine invasions and are found within each instance of invasion. The impact of ectomycorrhizal fungi and Pinus trees upon the properties of the soil within Eucalyptus forests is not very well studied nor understood. Our study sought to provide insight into the implications of this invasion upon the soil, and consequently the ecosystem as …
Assessing The Behavioral Impact Of Pyridostigmine Bromide In Rats, Noah A. Martin
Assessing The Behavioral Impact Of Pyridostigmine Bromide In Rats, Noah A. Martin
Honors Theses
Pyridostigmine bromide (PB) is an organophosphate (OP) nerve agent prophylactic used to protect warfighters against chemical warfare agents. OPs inhibit the neural enzyme acetylcholinesterase (AChE) in the brain. This leads to the buildup of acetylcholine, causing respiratory failure, seizures, and death. PB functions by inhibiting ~30% of peripheral AChE temporarily, protecting the enzymes so that the body is able to restore sufficient cholinergic function post-exposure. PB does not cross the blood-brain barrier, though it may still indirectly affect toxicity in the brain due to repeated AChE inhibition throughout treatment, or by inhibition of non-target ChE’s in the blood. The aim …

This study investigated bacterial microbiomes at varying depths (0, 10, 20, 30, and 40 cm) on Biloxi East Beach, on the Mississippi Gulf Coast, using 16S rRNA gene sequencing and assays of extracellular enzyme activity. 11,161 amplicon sequence variants (ASVs) were identified across all samples, with the most abundant bacterial phyla being Planctomycetota, Gammaproteobacteria, and Bacteroidota. Depth had a significant impact on bacterial community composition, with surface layers having more diverse bacterial communities. Microbial diversity …
Protective And Risk-Related Factors Associated With College Student Burnout, Dominic X. Chavez
Protective And Risk-Related Factors Associated With College Student Burnout, Dominic X. Chavez
Honors Theses
Burnout is an occupational phenomenon commonly defined by the exhaustion, cynicism, and lack of efficacy a person experiences with regard to their role (i.e., educator, healthcare worker, student, etc.). Despite the prevalence of burnout in academia, very few research studies have attempted to examine the variables associated with burnout’s severity in the case of American college and university students. Thus, the current study sought to analyze the protective and risk-related factors previously determined to be associated with academic burnout within a college population. Specifically, burnout self-ratings were compared to perceived burnout stigma, resilience, perceived social support, help-seeking attitudes, and perceived …

Asymmetric Effects Of The Ebbinghaus Illusion On Relative Depth Judgments In A Perceptual Matching Task, Caden J. Thompson
Honors Theses
The Ebbinghaus illusion, also know as Titchner Circles, is a perceptual illusion that is typically presented as a two-dimensional set of disks. These disks are configured as a central disk surrounded by an annulus of smaller or larger disks. Numerous studies have found the illusion to have an effect on size perception, but fewer studies have analyzed its effects on depth judgments. This study utilized a head-worn virtual reality environment as well as a three-dimensional display to examine the effects of the Ebbinghaus illusion on relative depth judgments in a perceptual matching task. Findings indicated that Ebbinghaus configurations featuring an …
Radicle Restoration: Growing Native Plant Seedlings For Changing Landscapes, Madelyn Moore
Radicle Restoration: Growing Native Plant Seedlings For Changing Landscapes, Madelyn Moore
Honors Theses
In the wake of great anthropogenic change in the landscape across eastern North America, there is a need for ecological restoration. Forests, in particular, are struggling due to the decline of previously dominant tree species and the need to protect the understory from persistent invasion. Forests cannot follow the typical path of natural development through secondary succession due to the interference of invasive species. Invasive species thrive in disturbed habitats, and they have a variety of adaptations that allow them to outcompete native species. Invasive species removal alone leads to their return to previously invaded sites. Instead, invasive removal should …
Characterization Of A Drosophila Crc 3-Hit Model Using Genetic Approaches, Sydney E. Anderson
Characterization Of A Drosophila Crc 3-Hit Model Using Genetic Approaches, Sydney E. Anderson
Honors Theses
Colorectal cancer (CRC) is the second leading cause of cancer deaths in the United States, resulting in the deaths of over 50,000 people every year (American Cancer Society, 2023). The similarities shared between mammal and Drosophila melanogaster anatomy within the intestinal tract make Drosophila a great model for studying colorectal cancer. This study will investigate tumor characteristics of a Drosophila CRC model generated by modulating three genes within the key Hippo pathway to create a 3-hit model: p53, RasV12, and APC. The gene combination in the 3-hit model closely emulates how CRC presents in humans and is therefore important to …
