"Don't Have Sex, You'll Get Pregnant And Die!": Female University Students' Experiences With Abstinence-Only Education, Jillian Grace Norwick

Theses and Dissertations--Family Sciences

Based on the various changes in sexual education, many schools throughout the United States still teach abstinence-only education. There is a plethora of literature on the effectiveness of sexual education programs as well as adolescent sexual practices. However, there is a deep gap in literature on students' perspectives of their sexual education and the possible effects it has on their experiences while in college. Therefore, this phenomenological study aims to explore and describe the essence of the experience female university students have regarding the abstinence-only education they received during secondary schooling. The informants (n=12) were 19-22 year old female university …

Variable Consequences Of Toxic Prey On Generalist Insect Predators, Kelly Jackson

Theses and Dissertations--Entomology

Introduced species, like the lady beetle Harmonia axyridis, have been linked to declines of native species through mechanisms including intraguild predation and competitive superiority. However, competitive differentials between species may be mitigated if subdominant species can utilize resources that dominant species cannot. Previous research has shown that some strains of the aphid Aphis craccivora are toxic to H. axyridis. My goal was to investigate use of this resource by both H. axyridis and other lady beetles, to determine whether these aphids might be an exploitable resource for subdominant lady beetle species. I first examined the behavioral responses of …

The Manipulation And Examination Of Wolbachia In Medically Important Mosquitoes, Timothy D. Mcnamara

Theses and Dissertations--Entomology

Mosquitoes are a major vector of human disease and result in massive costs to public health in affected regions. It has been suggested that Wolbachia pipientis could be used for mosquito population reduction. Wolbachia is a maternally-transmitted endosymbiont of arthropods and nematodes that infects the cytoplasm of host cells. In mosquitoes, Wolbachia manipulates reproduction through Cytoplasmic Incompatibility (CI), which is characterized by a cessation of embryonic development in certain crossing-types. However, the relationship between Wolbachia and its host is complex and not fully understood. The crossing relationships between naturally-infected and aposymbiotic populations of Culex pipiens pipiens and Culex pipiens molestus …

Educational Experiences Of Foster Children And Communication Patterns Of Key Stakeholders: The Foster Parent Perspective, Teresa Hardin

Theses and Dissertations--Family Sciences

This research explored the perspective of foster parents on the educational experiences of foster children and experiences of communication patterns with other key stakeholders (social workers, and teachers). Factors focused on were educational experience of foster children, communication patterns, the impact of communication patterns on the educational experience, and barriers to effective communication. Five individuals who were, at the time of the study, foster parents to at least one child were interviewed. Participants openly shared a variety of positive and negative experiences. This study adopted the theoretical framework of Bronfenbrenner’s cultural-ecological theory. Participant interviews were transcribed verbatim and inductive coding …

The Chemical Ecology Of Bed Bugs (Cimex Lectularius, L.) And The Impact Of A Neurotoxic Insecticide On Physiology And Behavior, Sydney E. Crawley

Theses and Dissertations--Entomology

Following a decades-long hiatus in many nations, populations of bed bugs (Cimex lectularius) have rebounded and are thriving on a global scale posing substantial challenges for pest management professionals. Insecticide resistance to both pyrethroid and neonicotinoid compounds has been identified in many populations, leading to renewed interest in alternative control methods for management of this pest. The objectives of my dissertation research were to study various, typically cryptic, bed bug behaviors in order to improve both conventional and alternative management strategies. Novel behavioral interactions among mother and offspring were characterized. Additionally, changes in behavior and physiology after treatment …

Endosymbiotic Bacteria In The Bed Bug, Cimex Lectularius L. (Hemiptera: Cimicidae), Mark H. Goodman

Theses and Dissertations--Entomology

The return of bed bugs to prominence as an urban pest has precipitated an emphatic research response from the scientific community in an effort to better understand their biology and management. However, not all aspects of bed bug biology have received equal attention. The role of symbiotic bacteria in the normal function and biology of insects is often underappreciated, and this is true of bed bugs. Bed bugs have two main endosymbiotic bacteria, a Wolbachia species and a poorly-characterized gamma-proteobacterium referred to as BLS. However, their interactions with the host are poorly understood. I explored various aspects of these symbionts …

Evaluation Of Diet Composition Of Pediatric Cancer Survivors As A Need For Nutrition Counseling, Sean O'Nan

Theses and Dissertations--Nutrition and Food Systems

Prior research has shown that pediatric cancer survivors face a multitude of longterm effects from treatment of their disease. Many of these conditions can be treated or managed through proper nutrition, however patients of the DanceBlue Kentucky Children's Hospital Hematology/Oncology Clinic do not see a registered dietitian. This study looked at food and drink consumption of the past 30 days by the patient using the NHANES Dietary Screener Questionnaire to see if they met nutrition recommendations as outlined by the 2015‐2020 Dietary Guidelines for Americans. Results from the study found that off‐treatment pediatric cancer survivors (n=21) failed to meet …

Do Beliefs About Sex Behaviors Mediate The Link Between Parent-Adolescent Communication About Sex And Risky Sexual Behaviors?, Guangyi Cui

Theses and Dissertations--Family Sciences

The current study examined the protective effect of parenting-adolescent communication about sex on four risky sexual behaviors (age of onset of sex, number of sex partners, condom use, and STDs) among youth, framed by the Theory of Planned Behavior. It also tested for potential mediation effects between parent-adolescent communication and risky sex measures by sexual cues, date rape attitudes, and acceptance of dating violence in a sample of 2,245 college students from Japan, Slovenia, Spain, and the United States. Results provided evidence of a weak effect of parent-adolescent communication about sex on risky sexual behaviors across samples. A number of …

A Controversial Bill (H.R. 897) To Mosquito Control Programs: A Policy Analysis, Charles Guissou

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The primary purpose of this paper was to analyze the legal, financial, and administrative burdens of the Pesticides General Permit on mosquito control programs from a policy perspective. Mosquito control is often highly controversial, particularly when it involves the use of pesticides that have their own potentially serious health and environmental impacts. In 2009, the Environment Protection Agency issued the permit to be obtained by pesticide applicators before pesticides could be discharged into waterways in addition to existing Federal Insecticides, Fungicides, and Rodenticides Act (FIFRA) regulations. Some provisions of the permit could impact mosquito control activities. Therefore, in response to …

Self Center: Addressing Teen Pregnancy In Wolfe County, Ky, Lindsey Smith

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Teen pregnancies and births are at an all-time low across the United States. Despite this decline in rates within the last decade, the teen pregnancy rate in Kentucky remains significantly higher than that of the overall United States. Additionally, teen pregnancy still has significant economic and health impacts on both teen parents and their children. In rural communities, such as Wolfe County, KY, teen birth rates are approximately one-third higher than the rest of the country. Self Center is an evidence-based teen pregnancy prevention program that involves school-linked reproductive health services and provides participants with education, counseling, and healthcare services. …

Effects Of Mountaintop Removal Mining On Population Dynamics Of Stream Salamanders, Sara B. Freytag

Theses and Dissertations--Forestry and Natural Resources

Mountaintop removal mining (MTR) is a notorious stressor of stream ecosystems in the Central Appalachians. Valley fills (VF) lead to reduced occupancy, abundance, and species richness of stream salamanders. Multiple factors may be responsible for these reductions, but specifically habitat fragmentation and degradation may reduce colonization rates and increase local extinction rates. From 2013-2015, repeated counts of salamanders were conducted in stream reaches impacted by MTR/VF and compared to counts in reference reaches to answer the question: do stream salamander population dynamics differ between stream reaches impacted by MTR/VF and reference stream reaches? I also investigated dynamics of stream habitat …

Automated Solid-Substrate Cultivation Of The Anaerobic Bacterium Clostridium Thermocellum, Mathew J. Ruwaya

Theses and Dissertations--Biosystems and Agricultural Engineering

The organism Clostridium thermocellum grows on cellulosic substrates and produces ethanol, acetate, lactate, formic acid, and CO₂. The organic acids produced alter the growth environment in which the bacteria grows and ultimately inhibit bacterial growth. One method which has been used successfully to maintain the system at acceptable growth conditions is to intermittently flush out the spent media and metabolic products and replace with new fermentation media. Our goal was to design and build an automated system that will automatically flush the spent media from the growing culture and resupply new media without manual intervention. An automated control …

Coordination Of Rna Polymerase Ii Pausing And 3' End Processing Factor Recruitment With Alternative Polyadenylation, Becky Fusby, Soojin Kim, Benjamin Erickson, Hyunmin Kim, Martha L. Peterson, David L Bentley

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Most mammalian genes produce transcripts whose 3' ends are processed at multiple alternative positions by cleavage/polyadenylation (CPA). Poly(A) site cleavage frequently occurs cotranscriptionally and is facilitated by CPA factor binding to the RNA polymerase II (Pol II) C-terminal domain (CTD) phosphorylated on Ser2 residues of its heptad repeats (YS₂PTSPS). The function of cotranscriptional events in the selection of alternative poly(A) sites is poorly understood. We investigated Pol II pausing, CTD Ser2 phosphorylation, and processing factor CstF recruitment at wild-type and mutant IgM transgenes that use alternative poly(A) sites to produce mRNAs encoding the secreted and membrane-bound forms of …

An Examination Of Maternal Stress And Secondhand Smoke Exposure On Perinatal Smoking Status, Karen R. Damron

Theses and Dissertations--Nursing

The median prevalence of smoking among women of childbearing age in the United States is 22.4%. Of women who identify themselves as smokers in the three months prior to conception, 55% quit during pregnancy; however, 40% of those who quit relapse and return to smoking within six months after delivery. Smoking has been identified as an important means of stress management among smokers in general, and though limited to the perinatal period, pregnancy-specific stress adds to a woman’s typical day-to-day stress burden. Little data exists as to the effect of SHS exposure on smoking status during pregnancy and the impact …

Consuming The Image: Hierarchies Of Beauty And Power In Us Latino, Colombian, And Dominican Cultural Productions, Angela Postigo

Theses and Dissertations--Hispanic Studies

This dissertation focuses on dominant contemporary depictions of women in order to investigate the related processes of producing and policing physical attractiveness and privilege in mainstream cultural productions. I examine how certain US Latina, Colombian, and Dominican female portrayals fit definite paradigms of ideal beauty and contribute to patterns of power within magazines, films and television, music, and literary novels. I explore the ways in which the majority of dominant representations in all three countries favor specific beauty ideals linked with an Anglo or Northern European archetype, thus limiting the acceptable model and excluding a great part of the racially …

Values For Recreational Beach Quality In Oahu, Hawaii, Jerrod M. Penn, Wuyang Hu, Linda Cox, Lara Kozloff

Agricultural Economics Faculty Publications

Pristine coastal environments are the key to Hawaii’s worldwide fame and attraction to tourists, yet their economic value remains understudied. This article examines preferences for characteristics associated with beach recreation in Oahu, Hawaii, among residents and tourists. Consideration is given to sand quality, water quality, congestion levels, and swimming safety conditions in the context of a choice experiment. The choice experiment conveys attribute levels almost entirely through pictures, and results suggest that this novel portrayal is well understood by respondents. Excessive congestion and water quality are regarded as the most important beach attributes, specifically the avoidance of poor water quality …

Continuous Time Multi-State Models For Interval Censored Data, Lijie Wan

Theses and Dissertations--Statistics

Continuous-time multi-state models are widely used in modeling longitudinal data of disease processes with multiple transient states, yet the analysis is complex when subjects are observed periodically, resulting in interval censored data. Recently, most studies focused on modeling the true disease progression as a discrete time stationary Markov chain, and only a few studies have been carried out regarding non-homogenous multi-state models in the presence of interval-censored data. In this dissertation, several likelihood-based methodologies were proposed to deal with interval censored data in multi-state models.

Firstly, a continuous time version of a homogenous Markov multi-state model with backward transitions was …

Ppap2b Expression Limits Lesion Formation In Murine Models Of Atherosclerosis, Paul A. Mueller

Theses and Dissertations--Physiology

Coronary artery disease (CAD) is the leading cause of death in both men and women worldwide and is defined as a narrowing of the coronary arteries due to accumulation of atherosclerotic plaques. Genome-wide association studies have identified risk loci within the gene PPAP2B that confers increased risk of developing CAD. Evidence suggests these aforementioned SNPs are regulating PPAP2B expression in a cis-manner through the interruption of transcription factor binding sites. PPAP2B encodes the lipid phosphate phosphatase 3 enzyme that plays a key role in degrading bioactive lysophosphatidic acid (LPA). LPA has a plethora of effects on vascular tissue and is …

Sglt2 Inhibitor Therapy Improves Blood Glucose But Does Not Prevent Diabetic Bone Disease In Diabetic Dba/2j Male Mice, Kathryn M. Thrailkill, R. Clay Bunn, Jeffry S. Nyman, Mallikarjuna R. Rettiganti, Gael E. Cockrell, Elizabeth C. Wahl, Sasidhar Uppuganti, Charles K. Lumpkin, John L. Fowlkes

Barnstable Brown Diabetes Center Faculty Publications

Persons with type 1 and type 2 diabetes have increased fracture risk, attributed to deficits in the microarchitecture and strength of diabetic bone, thought to be mediated, in part, by the consequences of chronic hyperglycemia. Therefore, to examine the effects of a glucose-lowering SGLT2 inhibitor on blood glucose (BG) and bone homeostasis in a model of diabetic bone disease, male DBA/2J mice with or without streptozotocin (STZ)-induced hyperglycemia were fed chow containing the SGLT2 inhibitor, canagliflozin (CANA), or chow without drug, for 10 weeks of therapy. Thereafter, serum bone biomarkers were measured, fracture resistance of cortical bone was assessed by …

Effect Of Mass Media On Family Planning Choices In Indonesia, Beta Ardiansyah

MPA/MPP/MPFM Capstone Projects

Realizing the necessity of family planning, the Indonesian government started family planning programs in the late 1960s, long before the global Program of Action from the International Conference of Population (ICPD) in 1994.

Many studies have tried to draw plausible explanations for the prevalence of family planning focused mainly on socio-economic factors but few studies have approached the issue from the perspective of mass media influence as the variable of interest. This study attempts to fill this gap created by the lack of empirical evidence about mass media effects of family planning choices by examining the contraceptive behavior of Indonesian …

Does The Mentors & Meals After School Program Have An Effect On Student Grades?, Lisa Caswell Johnson

MPA/MPP/MPFM Capstone Projects

While technology continues to progress and the United States continues to be considered one of the most privately wealthy nations in the world, the education gap for African American and Hispanic students continues to be a concern for teachers, school administrators, state and local politicians, and all who study public education policy. School districts persistently look for ways to improve student achievement in traditional as well as non-traditional ways, while aligning with state and local education goals and staying within budget.

This study examines a new mentoring model for middle school students. The program, Mentors & Meals (M&Ms), was the …

Recommendations For Vocal Pedagogy Curriculum Based On A Survey Of Singers’ Knowledge And Research In Vocal Hygiene, Diana Lindsey Vetter

Theses and Dissertations--Music

Professional voice users such as singers and teachers are at high risk for vocal injury. A literature review was conducted to understand the prevalence of voice problems and the effectiveness of vocal hygiene education. The findings of the review suggested that in order to reduce the impact of voice disorders, it is imperative that the education of singers and teachers include how the voice functions and how to best take care of it.

The purpose of this study was to discover what students on a collegiate level know about vocal anatomy, physiology, and vocal hygiene issues. It was hypothesized that …

Effects Of Epichloë Coenophiala−Tall Fescue Symbiosis On Plant-Microbe-Soil Interactions In A Temperate Pasture, Lindsey C. Slaughter

Theses and Dissertations--Plant and Soil Sciences

Plants interact in myriad ways with microorganisms to influence ecosystem processes such as nutrient cycling, which can regulate ecosystem response to global change. One important plant-microbe symbiosis occurs between cool-season grasses and asexual fungal Epichloë endophytes, such as tall fescue (Schedonorus arundinaceus) and Epichloë coenophiala. Because the common toxic strain of the endophyte (CTE) harms grazing livestock, non-livestock toxic endophyte (NTE) strains have been developed and are increasingly deployed in pastures. Little is known about how these symbioses impact other plant-microbe interactions and microbe-mediated soil processes in grassland ecosystems. I conducted three studies to determine how E. …

Insights Into Triterpene Metabolism In Model Monocotyledonous And Oilseed Plants Genetically Engineered With Genes From Botryococcus Braunii, Chase F. Kempinski

Theses and Dissertations--Plant and Soil Sciences

Isoprenoids are one of the most diverse classes of natural products and are all derived from universal five carbon, prenyl precursors. Squalene and botryococcene are linear, hydrocarbon triterpenes (thirty carbon compounds with six prenyl units) that have industrial and medicinal values. Squalene is produced by all eukaryotes as it is the first committed precursor to sterols, while botryococcene is uniquely produced by the green algae, Botryococcus braunii (race B). Natural sources for these compounds exist, but there is a desire for more renewable production platforms. The model plant Arabidopsis thaliana was engineered to accumulate botryococcene and squalene in its oil …

Investigation Into The Cell Wall And Cellulose Biosynthesis In Model Species And In The C4 Model Plant Setaria Viridis, Mizuki Tateno

Theses and Dissertations--Plant and Soil Sciences

A uniform feature of all plant cells is the presence of a cell wall. The cell wall functions in facilitating directional expansion and is therefore important for cell shape and morphogenesis. All plant cell walls contain cellulose microfibrils embedded in a network of polysaccharides, lignin and protein. Cellulose is evolutionarily conserved and is made by all plants as well as other members of various taxonomic kingdoms. From a human perspective, the field of renewable energy has had an ever increasing interest in using the cell wall for production of renewable platform chemicals and fuels. However, the biosynthesis of these components …

Does The Pain Of Rejection Promote The Pleasure Of Revenge? A Neural Investigation Of Cingulo-Striatal Contributions To Violence, David Chester

Theses and Dissertations--Psychology

Aggression is a dynamic and costly feature of human behavior. One reliable cause of aggression is social rejection, though the underlying mechanisms of this effect remain to be fully understood. Previous research has identified two psychological processes that are independently linked to aggressive retaliation: pain and pleasure. Given recent findings that pain magnifies the experience of pleasure, I predicted that the pain of rejection would promote the pleasure of aggression and thus, aggression itself. I also expected that this indirect effect of aggressive pleasure would only be observed among individuals with weaker self-regulatory abilities that are necessary to cope with …

Women In White: A Retrospective Look At Medical Education At One School Before Title Ix, Karen Clancy

Theses and Dissertations--Educational Policy Studies and Evaluation

The Women in White generation of women physicians who graduated from American medical schools between World War II and the enactment of Title IX were trailblazers. They successfully pursued and achieved physician careers during a time when doctoring was still considered “man’s work.” They helped to clear a path to a modern medical student culture where women and men had more choices.

In a 2008 oral history interview, Dr. Jacqueline Noonan, world-renowned pediatric cardiologist, discoverer of the congenital heart condition known as “Noonan Syndrome,” and the first woman appointed to a chairman role at the University of Kentucky College of …
