Parent And Child Perceived Coping Socialization During Peer Conflict: A Qualitative Study, Janet W. Kwan
Parent And Child Perceived Coping Socialization During Peer Conflict: A Qualitative Study, Janet W. Kwan
Theses and Dissertations
Despite budding research on parent-child discrepant perceptions of a child’s psychosocial functioning, the potential difference in individual perception of coping socialization is unclear. Further, literature suggests the onset of various impulse-control disorders occurs around middle childhood. Thus, the current study used a phenomenological approach and thematic analysis to examine perspectives of coping socialization, identify intended take away messages, and examine the perceived impact of inconsistent understanding of the interaction. Results indicated both parents and children use verbal and physical cues to understand one another during coping socialization and that their lab discussion was representative of their typical interactions. Themes emerged …

Distributed Predictive Control For Mvdc Shipboard Power System Management, Nasibeh Zohrabi
Distributed Predictive Control For Mvdc Shipboard Power System Management, Nasibeh Zohrabi
Theses and Dissertations
Shipboard Power System (SPS) is known as an independent controlled small electric network powered by the distributed onboard generation system. Since many electric components are tightly coupled in a small space and the system is not supported with a relatively stronger grid, SPS is more susceptible to unexpected disturbances and physical damages compared to conventional terrestrial power systems. Among different distribution configurations, power-electronic based DC distribution is considered the trending technology for the next-generation U.S. Navy fleet design to replace the conventional AC-based distribution. This research presents appropriate control management frameworks to improve the Medium-Voltage DC (MVDC) shipboard power system …

Landowner Perceptions Of Oil And Gas Development In Mississippi And Policies Associated With Managing The Industry And Natural Resources, Rachael Carter
Theses and Dissertations
Advances in oil and gas drilling technologies have led to an on-shore shale boom in the United States. This has increased drilling on forest land and conflicts regarding the tradeoffs of this practice. This study examines the forest landowner perspective of oil and gas development on forest land, policies that regulate the industry, opinions of land use tradeoffs, and what influences landowner decision making. This study also examines the balance of power between federal, state, and municipal government regarding the regulation of the oil and gas industry. A systematic random sample of 1200 landowners with more than 10 acres of …
Beta Diversity Provides Evidence Of Niche Based Assembly In Temperate Forest Understory Assemblages Of Mississippi, David Steven Mason
Beta Diversity Provides Evidence Of Niche Based Assembly In Temperate Forest Understory Assemblages Of Mississippi, David Steven Mason
Theses and Dissertations
Assembly is a process that shapes the abundance and identity of species in a community. Niche and neutral theory explain assembly processes with mechanisms driven by either species differences, or functional equivalence and stochastic dispersal. In 2017 I sampled vegetation and environmental variables at 59 sites in the Noxubee National Wildlife Refuge and Tombigbee National Forest of Mississippi to explore forest understory community assembly. I developed and assessed a framework of predictions concerning general patterns and underlying mechanism. Evidence of dispersal limitation and functional equivalence were expected under neutral theory. Local environmental characteristics, surrounding landscape variables, and fire were significant …

Understanding How Pin1-Substrate Interactions Modulate Affinity And Inter-Domain Dynamics, Hewa Pathiranalage Dinusha Sanjeewani Jinasena
Understanding How Pin1-Substrate Interactions Modulate Affinity And Inter-Domain Dynamics, Hewa Pathiranalage Dinusha Sanjeewani Jinasena
Theses and Dissertations
Pin1 is an essential peptidyl-prolyl isomerase (PPIase) that catalyzes cis-trans prolyl isomerization in proteins containing phosphorylated serine/threonine-proline motifs (pSer/Thr-Pro). It has an N-terminal binding domain (WW) and a C-terminal PPIase domain. Pin1 targets pSer/Thr-Pro motifs by its WW domain and catalyzes isomerization through its PPIase domain. This dissertation is focused on elucidating the interactions between Pin1/substrate, the inter-domain dynamics upon binding, and the catalytic activity of Pin1 upon binding different substrates. Specifically, we investigated the Pin1-Histone H1 interaction and designed a series of chimeric peptides based on the H1.4 sequence (KATGAApTPKKSAKW). NMR titrations were performed for each peptide using both …

Using The Unified Theory Of Acceptance And Use Technology To Determine Factors That Affect The Acceptance And Use Of Social Media To Advertise And Promote Agriproducts In Farmer' Communities In North Mississippi, Carlos Alberto Moreno-Ortiz
Theses and Dissertations
The present empirical study examined factors that affect the acceptance and use of social media platforms by farmers and vendors in farmers’ communities in North Mississippi for marketing their small farm businesses. Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), structural equations modeling was used to examine several relationships: (1) the influence of performance expectancy (PE) on behavioral intention (BI) to use social media; (2) the influence of effort expectancy (EE) on BI; (3) the influence of social influence (SI) on BI; (4) the influence of facilitating conditions (FC) on actual use (USE) of social media; …
Stress-Buffering Of Social Support On Depressive Problems: Moderation By Parental Depressive Problems, Erica Marie Szkody
Stress-Buffering Of Social Support On Depressive Problems: Moderation By Parental Depressive Problems, Erica Marie Szkody
Theses and Dissertations
The impact of parental depressive problems on children’s depressive symptoms has been widely studied. The Stress Buffering Hypothesis states that social support acts as a protective factor between the impacts of stress from negative life events on physical and psychological health. The current study examined the stress buffering hypothesis in terms of the relationship between parental depressive problems and emerging adult depressive problems. The differential buffering strength of both perceived social support and received social support between stress from negative life events and depressive problems were examined along with the moderating effects of parent and emerging adult gender. Neither perceived …
System Dynamics Model Of Necrotic Enteritis And Its Predisposing Factors In Broilers, Yu-Bin Chou
System Dynamics Model Of Necrotic Enteritis And Its Predisposing Factors In Broilers, Yu-Bin Chou
Theses and Dissertations
Necrotic enteritis (NE) caused by Clostridium perfringens type A is an important bacterial enteric disease of global broiler production. However, the dynamic interactions of NE and its predisposing factors are not fully presented by current studies. By using the System Dynamics (SD) Model, the epidemiological changes in susceptible-infected-removed models of NE and avian coccidiosis and their interactions in one or multiple grow-out cycles was established; meanwhile, the growth performance was measured by the average weights of infected and non-infected populations at harvest were estimated. The SD model provided direct and persuasive outcomes of the epidemiology and ecology of NE compared …
Tailoring Math Curricula For Community Colleges: A Process Approach, Ira Lindsay Mcfarland Kinard
Tailoring Math Curricula For Community Colleges: A Process Approach, Ira Lindsay Mcfarland Kinard
Theses and Dissertations
Community college instructors continue to search for effective instructional methods that promote student success in developmental mathematics courses such as intermediate algebra. According to research, mathematics is a major obstacle for students succeeding, persisting, and completing community college programs. Each student enrolled in intermediate algebra has an ACT sub-score of 16 to 18 or an ACCUPLACER sub-score of 57 to 75. Most community colleges in Mississippi use placement testing to determine the strengths and needs of students. However, students approach math with high anxiety, more than any other areas, which interferes with their learning. Research indicates that to improve students’ …

In order to adequately address the differences in stress levels for African-Americans, this study examined the data from an existing study called the Jackson Heart Study. Based on the weekly stress of individuals when performing their occupations, information and data were collected from 3 questionnaires that were correlated with stress and occupations of African-Americans in Mississippi. These questionnaires were the Household Enumeration Form, Personal Data and Socioeconomic Form, and the Stress Form. The research design …
Improving Dropout Rates In Mississippi Schools: A Case Study Examining Effective Dropout Prevention Programs In Mississippi High Schools, Shevonda Williams Truman
Improving Dropout Rates In Mississippi Schools: A Case Study Examining Effective Dropout Prevention Programs In Mississippi High Schools, Shevonda Williams Truman
Theses and Dissertations
The dropout rate for many Mississippi high schools has improved tremendously over the last decade. In 2017, the Mississippi Department of Education reported that the dropout rate for the State declined form 13.9% to 10%. This rate was only 4% higher than the national average. However, with all the research that pertains to student dropouts and the success many states are seeing, there are still school districts failing to show improvement. Many high schools have dropout rates in excess of 20%. This study explored the perceptions of district high school principals, counselors, and other administrators working in schools with students …
Individual Differences In Creative Cognition, Sarah K. Craig
Individual Differences In Creative Cognition, Sarah K. Craig
Theses and Dissertations
Creativity is increasing in value worldwide, but the processes underlying various creative abilities remain ambiguous. The most frequently used assessments of creativity (i.e., divergent thinking tasks; creative problem-solving tasks) differ in surface features and are also rarely examined together. These inconsistencies, in addition to mixed findings in the literature, have caused considerable debate among creativity researchers concerning the particular roles of independent or dual processes that lead to success on different creativity tests. The present study expounded upon these mixed findings using a factor analytic method. The results indicated that individual differences in working memory and fluency ability impact performance …
Functional Role Of Protein Kinases And Phosphatase In Abiotic Stress Response In Plants, Saroj Kumar Sah
Functional Role Of Protein Kinases And Phosphatase In Abiotic Stress Response In Plants, Saroj Kumar Sah
Theses and Dissertations
Soybean (Glycine max) and rice (Oryza sativa) are the most important crops cultivated worldwide. The productivity of both crops is severely limited due to drought stresses. Abscisic acid (ABA) signaling is one of the crucial phytohormones which acts as the signaling mediator in different environmental stress for adaptive response of plants. In this study, functional characterization of abscisic acid-activated protein kinase-like kinase 1 (AALK1), and low molecular weight protein tyrosine phosphatase (LMWPTP) were studied by developing gain-ofunction and loss-ofunction phenotypes by transgenesis. Physiological response of AALK1 showed that AALK1 modulates the drought stress response ins soybean plants. The study has …
Genetics Of Sexually Dimorphic Development Of Butterfly Wing Patterns, Luis Fernando Rodriguez Caro
Genetics Of Sexually Dimorphic Development Of Butterfly Wing Patterns, Luis Fernando Rodriguez Caro
Theses and Dissertations
Butterfly wing color patterns result from the arrangement of monochromatic scales containing chemical pigments and a delicate architecture that can cause interference or diffraction of light, generating iridescent colors. The latter mechanism is known as structural coloration and, despite its ecological importance, little is known about the molecular mechanisms underlying the development of this trait. The Southern Dogface butterfly, Zerene cesonia, exhibits sexually dimorphic development of ultraviolet wing reflectance. Males possess a UV-reflective patch on the forewing that results from nano-structures on the wing scales, which are absent in females. This dimorphism offers an excellent opportunity to explore the genetic …
History, Status, And Resource Selection Of The American Black Bear In Mississippi, Stephanie Lynn Simek
History, Status, And Resource Selection Of The American Black Bear In Mississippi, Stephanie Lynn Simek
Theses and Dissertations
Historically, black bears occurred throughout Mississippi but by 1932, <12 bears remained. Repatriation in neighboring states and conservation efforts in Mississippi have led to the recolonization of at least 2 subspecies (U. a. luteolus and U. a. americanus) of black bears in the state. I compiled available data to provide a synthesis of the history, current status, and management of black bears in Mississippi. Additionally, I used global positioning data collected from radio collared bears to determine the influence of distance to source population, cover type, distance to roads, distance to water, wetland reserve program areas, and human population density on black bear resource selection at various spatial scales. I studied characteristics of space use and resource selection of recolonizing bears in the Mississippi Alluvial Valley (Delta). I assessed the influence of environmental parameters at the female core annual home-range (using 50% kernel density estimator) and male and female seasonal and annual home-ranges (95% kernel density estimator). Distance to source population and distance to roads had significant influence at the core female home-range scale. I found a sex-based difference in annual and seasonal home-ranges. I also found that bears exhibited response to and selection for specific resources with an affinity toward hardwood stands, particularly young-aged hardwoods. My research illustrates the importance of analyzing resource selection at multiple scales to gain a full understanding of parameters that influence the recolonization of a bear population.

Impact Of Integrated Vegetation Management Practices On Green Antelopehorn Milkweed (Asclepias Viridis Walter) In Right-Of-Ways And Forages, Nolan Hendrix Thorne
Theses and Dissertations
Common integrated vegetation management (IVM) practices including herbicide and mowing applications on right-of-ways and forages were evaluated on green antelopehorn populations near Starkville, MS. Live stems in each plot were counted prior to treatment application and approximately one year after treatment (YAT). Analysis of the stem counts 1YAT indicated aminopyralid+metsulfuron, imazapyr, picloram+2,4-D, maximum rates of triclopyr ester or choline, glyphosate, imazapyr+aminocyclopyrachlor+metsulfuron reduced the number of green antelopehorn stems compared to the untreated. Aminocyclopyrachlor, aminocyclopyrachlor+chlorsulfuron, aminopyralid, aminopyralid+2,4-D, dicamba+2,4-D, foramsulfuron+iodosulfuron+thiencarbazone, fluroxypyr, hexazinone, metsulfuron, metsulfuron+chlorsulfuron, nicosulfuron+metsulfuron, sulfometuron, sulfosulfuron or low rates of triclopyr did not reduce the stem count 1YAT when compared to …
Implementation And Evaluation Of A School-Based Anti-Tobacco Program In Mauritius: A Pilot Study To Assess The Usefulness And Reliability Of A Tobacco Use Prevention Education Instrument, Shariah Hussenbocus
Implementation And Evaluation Of A School-Based Anti-Tobacco Program In Mauritius: A Pilot Study To Assess The Usefulness And Reliability Of A Tobacco Use Prevention Education Instrument, Shariah Hussenbocus
Theses and Dissertations
Tobacco use among Mauritian adolescents has increased steadily since 2008. Currently, Mauritius has not implemented any school-based anti-tobacco program and there is no instrument to assess the effectiveness of existing anti-tobacco school policies. Since the first cigarette can rapidly lead to nicotine dependence, targeted interventions must be assessed before established patterns of smoking appear. This study evaluated a tobacco use prevention education instrument to determine the effectiveness of a school-based anti-tobacco program. 26 male students completed a survey before and after receiving anti-tobacco lessons. Smoking initiation age could not predict likelihood of tobacco addiction (r(12)=0.320, p=0.311). However, after receiving the …
Examining The Stigma Of Sex Offending In The Media, The Community, And The Prison, Kristen Lynn Stives
Examining The Stigma Of Sex Offending In The Media, The Community, And The Prison, Kristen Lynn Stives
Theses and Dissertations
The overarching goal of the current work was to explore sanctions experienced by sex offenders prior to incarceration, during incarceration, and after their release using three separate but interrelated studies. The first study analyzed how the media framed sex offenders, and how this compared to the media’s portrayal of murderers. The study used a content analysis of newspaper articles published in 2007, the year after the Adam Walsh Safety and Protection Act was passed, and 2017. Open coding (the identification of categories and concepts) and axial coding (the process of relating categories and concepts) strategies were used. Findings showed that …
False Memories In Recognition Memory: Recollection Or Familiarity?, Alexis E. Payne
False Memories In Recognition Memory: Recollection Or Familiarity?, Alexis E. Payne
Theses and Dissertations
False recollection refers to the retrieval of contextual information associated with an event that has not occurred. For instance, during a recognition task, one might identify a nonstudied word presented at test as old because she remembers the font color of the word during study. Although instances such as this are rare and typically occur at a varying rate of 0-5%, current models of recognition such as the Complementary Learning Systems (CLS) model and the Dual-Process Signal-Detection (DPSD) model do not contain a mechanism to account for their occurrence. Although both the CLS and DPSD models have support from studies …
How To Avoid Becoming The Accomplice To Your Own Murderers: Reading James Baldwin As A Critical Pedagogue, Breana Shrease Miller
How To Avoid Becoming The Accomplice To Your Own Murderers: Reading James Baldwin As A Critical Pedagogue, Breana Shrease Miller
Electronic Theses and Dissertations Archive
James Baldwin is a well-known author and activist in American literature. He had long been a champion of civil rights, using his platform to speak about the iniquities and issues affecting black people in America. Though his work is read often in literary circles, his writing could serve to supplement the field of critical pedagogy with Rhetoric and Composition. Paulo Freire, the conceiver of critical pedagogy through his foundational text Pedagogy of the Oppressed, identified the pitfalls of educational systems that see teachers as knowledge-givers and students as knowledge receptacles based on his experiences teaching illiterate adults in Brazil under …
Transcriptome 3′End Organization By Pcf11 Links Alternative Polyadenylation To Formation And Neuronal Differentiation Of Neuroblastoma, A Poetsch, S Danckwardt
Transcriptome 3′End Organization By Pcf11 Links Alternative Polyadenylation To Formation And Neuronal Differentiation Of Neuroblastoma, A Poetsch, S Danckwardt
School of Biomedical Sciences
Diversification at the transcriptome 3'end is an important and evolutionarily conserved layer of gene regulation associated with differentiation and dedifferentiation processes. Here, we identify extensive transcriptome 3'end-alterations in neuroblastoma, a tumour entity with a paucity of recurrent somatic mutations and an unusually high frequency of spontaneous regression. Utilising extensive RNAi-screening we reveal the landscape and drivers of transcriptome 3'end-diversification, discovering PCF11 as critical regulator, directing alternative polyadenylation (APA) of hundreds of transcripts including a differentiation RNA-operon. PCF11 shapes inputs converging on WNT-signalling, and governs cell cycle, proliferation, apoptosis and neurodifferentiation. Postnatal PCF11 down-regulation induces a neurodifferentiation program, and low-level PCF11 …

Afterschool Educators' Teaching Practices Through Tinkering: Nurturing Student Collaboration, Engagement, And Development Of Self-Confidence, Lianna Kali
Master's Theses
Since the early 2000s constructionist pedagogy has become an increasingly popular trend in both formal and informal science, technology, engineering, art, and math (STEAM) learning environments to support transformative educational outcomes through the making of personally meaningful objects and artifacts. But with this rise in popularity comes a challenge for educators: understanding what are the teaching practices that are most effective in a maker-centered learning environment to support student learning. Through an ethnographic case study of the teaching practices in a tinkering afterschool program, this study examines the core pedagogical facilitation moves of tinkering educators and investigates how those moves …

Catholic School Teachers' Attitudinal Beliefs About Linguistic Diversity, Katie Trautman
Catholic School Teachers' Attitudinal Beliefs About Linguistic Diversity, Katie Trautman
Master's Theses
As the population of young Catholics becomes increasingly culturally and linguistically diverse (CLD), Catholic schools must work to become more responsive to the needs of CLD students in order to uphold the tenets of Catholic social teaching and to sustain enrollment in Catholic schools. Catholic school teachers need to become more prepared to serve students from various linguistic backgrounds. As a component of this preparation, teachers must demonstrate positive beliefs toward linguistic diversity and students’ backgrounds as teachers’ attitudes toward students greatly impacts students’ learning and identity development. Using Catholic social teaching as a lens, this study investigated Catholic school …
Now Hiring: Exploring Deportee Transnational Identities And Socio-Economic Reintegration In Baja California, Mexico’S Call Center Industry, Brenda Vargas
Master's Theses
The anti-immigrant rhetoric in the U.S. intensified deportation, including that of Mexican and Salvadorian migrants with some having served in the U.S. military. Despite weak social connections and explicit/structural barriers in Mexico, many deportees make the decision to stay in Mexico. The focus of this thesis is male deportees belonging to the “1.5 generation,” aged late 20’s-early 60’s, who, after spending their childhood and adulthood in the U.S., have undergone deportation and are faced with social and economic reintegration in the northern border area of Baja California, Mexico. Through 15 in-depth semi-structured interviews, I explore transnational identity negotiations that impact …
