Show moreInfluenza is one of the most common diseases worldwide, yet the vaccines against influenza are only 35% effective at protecting against infection. Creating a more effective vaccine requires an understanding of the foundation and the factors that contribute to a strong and protective adaptive immune response. T-bet [TBX21] is a transcription factor that plays an instrumental role in the orchestration of the type 1 immune response, which is the specialized response used by the immune system for a cell-mediated response against intracellular pathogens, such as influenza. It has yet to be explored in an influenza setting on the role T-bet in the production of antibodies. The aim of this study is to understand T-bet's role in production of antibody isotypes and identify whether expression of T-bet is more important for antibody production in T cells or B cells. We expected T-bet knockout (KO) mice to have IgG2a and that T-bet expression would be more important in T cells for antibody production. An enzyme-linked immunosorbent assay (ELISA) was used to measure the amount of virus-specific antibody in T-bet KO versus wild type (WT) mice infected with influenza. The results show that the T-bet KO and WT mice have relatively the same amount of IgG and IgG1, but the T-bet KO have a significantly lower level of IgG2a, confirming T-bet's importance for its production. To distinguish the importance of T-bet expression while T-bet expression in T cells was constant, a model was developed to allow us to control expression of T-bet in B cells. The results however were inconclusive, and the experiment will have to be repeated to make a firm conclusion on the roles of lymphocytes in the control of IgG isotypes. Overall, these results indicate that the manipulation of T-bet expression can be used as a vector to control IgG antibody levels, which holds potential for the improvement of vaccines.

Show moreThere is a void that exists within the discretionary behavior literature as it pertains to the counterproductive work behavior (CWB) and organizational citizenship behavior (OCB) relationship, respectively. The present study examined the moderating effects of moral identity on the relationship between CWB and OCB. In addition, exploratory analyses using moral identity sub-dimensions, organizational fairness, and job satisfaction were conducted. The study recruited 254 participants using MTurk. Using moderated multiple regression, a moderating effect for internalization (a moral identity sub-dimension) was revealed for the relationship between the organizational sub-dimensions of CWB and OCB. Other moderation analyses proved to be non-significant. Theoretical and practical implications of results are discussed. Future research should implement a longitudinal design to help determine causality for the moderation finding, as the current study used cross-sectional data. Findings from this study could be used to help fill the CWB to OCB literature void previously mentioned.

Show moreThe lesbian, gay, bisexual, and transgender (LGBT) community is a unique population that has specific health issues and health care needs associated with lifestyle behaviors that increase risk for certain diseases. Health concerns include mental and behavioral health, issues associated with gender identity and relationships (i.e. intimate partner violence), sexually transmitted infections, and chronic illnesses. The research suggests poorer health outcomes for the LGBT population compared to heterosexual and/or cisgender counterparts. Most research conducted with LGBT populations occurred in more populated urban settings with very few studies focusing on this population in the rural context. Consequently, there is a paucity of information on the health care concerns of the rural LGBT population. Considering the information gap, this integrative review of 14 research articles focused on health-related issues of the LGBT population in rural regions. The findings revealed rural LGBT persons experience disparities in accessing health care and support services; coupled with health care providers who often were not culturally competent; and, sometimes, unfamiliar with evidence-based health care protocols when caring for the LGBT patient. Implications for nursing research, education, practice, and policy and study limitations are highlighted.

Show moreFarmers around the world aim to use soil with adequate nutrients to produce sufficient and quality crops to the world's ever-growing population. Unbalanced use of nutrients in the soil will lead to soil deficiency, which is usually seen in South and Southeast Asian countries. This soil deficiency is often due to loss of micronutrient(s) within the soil from farming practices. Micronutrient deficiency affects not only plant growth but human health. Plants grown in nutrient deficient soil produce food with nutrient deficiencies, which affect people dependent on these foods for nutrients (Kathmandu, 2004). Nutrient deficient diseases and disorders like malnutrition are often seen in such cases. Current farming practices often involve leaching, mineralization, and bioconversion, which result in 50-70% loss of micronutrients. Smart practices from nanotechnology can lead conventional farming to more sustainable agriculture (Chhippa, 2016). This study aims to improve the dispersibility and uptake of zinc in plants different dual combination of ‘green' capping agents in zinc nanoparticles. The results of this study suggest tomato plants treated with urea coated with 3% Zn (w/w) using NAC-SAL ZnO showed a higher number of leaves and number of fruits set compared to controls.

Show moreThe mutability of prejudicial attitudes can be elucidated by taking into account the declines in cognition that tend to emerge as we age. This study aimed to assess whether there is a relationship between prejudice towards different ethnic groups and cognitive flexibility throughout adulthood. Ninety-five older adults and 118 younger adults were asked to complete an electronic survey encompassing measures of cognitive flexibility, social desirability, personality, optimism, empathy, ethnic attachment and prejudice. It was hypothesized that older adults would report lower levels of cognitive flexibility and higher levels of ethnic attachment in comparison to younger adults, which would in turn make the inverse relationship between cognitive flexibility and prejudice stronger in older participants. The results did not support the hypotheses predicting that there would be cohort differences in cognitive flexibility and ethnic attachment. As expected, there was a negative correlation between prejudice and cognitive flexibility, but it was only significant in younger adults before controlling for the influence of social desirability. Additionally, regression models predicting prejudice based on cognitive flexibility and ethnic attachment were significant before and after controlling for social desirability, but only in younger adults. Exploratory analyses indicate that the strength of the correlations between all study variables were generally lower in older adults. The findings presented here raise an argument for evaluating how the interplay between prejudice and cognitive flexibility may change in the later stages of life.

Show moreBackground: Intradialytic hypotension is a potential complication experienced by patients with end-stage renal disease who receive hemodialysis. This complication occurs during the dialysis treatment in 15-30% of all treatments. The multiple comorbidities that exist in hemodialysis patients predispose them to recurrent intradialytic hypotension episodes. Recurrent intradialytic hypotensive episodes can result in negative short-term and long-term clinical consequences. Short-term consequences include complications such as ischemic events (e.g., heart attacks, strokes), clotting of patient dialysis access, or heart rhythm abnormalities. Long-term consequences include end-organ damage, increased cardiovascular morbidity, and a higher mortality rate. Problem Statement: Available nursing interventions used to treat intradialytic hypotension such as decreased dialysis fluid temperature, changes in the calcium and sodium concentrations in the dialysis fluid and oral medication have limited success. Another existing technological intervention called blood volume monitoring shows greater potential success but is currently underutilized. Purpose: The purpose of this literature review is to synthesize current literature on blood volume monitoring technology used to prevent intradialytic hypotension in hemodialysis patients. Methods: A literature review was conducted analyzing pertinent research articles published in the last ten years, in addition to seminal articles. Seventeen articles were retrieved and analyzed that met criteria. Results: Fourteen of the seventeen research studies reached a consensus on the successful use of blood volume monitoring to decrease intradialytic hypotension and the related symptoms. Conclusion: Results of the literature review support the use of blood volume monitoring technology as an effective nursing intervention to prevent intradialytic hypotension in hemodialysis patients.

Show moreIt has been shown that popular crime television series can have an impact in the behavior and perception of viewers. Forensic evidence, or evidence that is gathered through scientific methods, is often central to the plot of these shows. Exposure to forensic evidence in these shows has impacted the legal system by changing perceptions and opinions towards evidence presented in courtrooms, a consequence termed the CSI effect. A subset of the CSI effect named the Police Chief's Effect refers to the ability of criminals to learn about forensic evidence from these shows. Although understudied, the Police Chief's effect has the potential to increase the difficulty of criminal investigations if criminals are better able to plan their actions and conceal evidence. The intent of this thesis is to explore a relationship between forensic techniques portrayed in television and the forensic knowledge an individual obtains from it. Previous studies have looked at the Police Chief's effect in the context of a non-violent crime, even though most of the television shows highlight crime of a violent nature. The present study evaluates the ability of participants to consider forensic evidence when planning a murder, taking into account their crime show viewing history. The results revealed that the overall number of crime shows, percentage of those episodes and involvement in the shows was not associated with forensic evidence. However, a moderate correlation was found between the number of crime shows watched and forensic evidence in female participants.

Show moreChildren are considered a vulnerable population in society. While thermoregulation in children is similar to that of an adult, children are vulnerable to heat-related illness. Student athletes have been found to be particularly vulnerable to heat-related illness for numerous reasons, including intense outdoor play. Football players are perhaps the most at-risk population of student athletes due to the intense physical requirements, outdoor practice during the hottest months of the year, and the extensive protective equipment required. By conducting a literature review on the subject of pediatric heat illness, the purpose of this thesis is to explore evidenced based research and guidelines regarding heat-related illness prevention. This review of literature was conducted through the utilization of the University of Central Florida's online databases using the EBSCOhost platform of: CINAHL Plus with Full Text, Cochrane Database of Systematic Reviews, ERIC, Health Source: Nursing/Academic Edition, MEDLINE, PsycINFO and SPORTDiscus. This thesis is unique because it does not focus on an individual sport; rather, it focuses on pediatric athletes from various disciplines. The prevalence, pathophysiology, prevention, and treatment of heat-related injuries are complex phenomena requiring the attention of law makers, athletic associations, school officials, coaches, athletic trainers, parents, and students.

Show moreThe optimal defense hypothesis predicts that the allocation of plant defenses across plant organs is proportional to the importance of a given organ to plant fitness. Despite this, much less work has been devoted to the study of reproductive defenses in plants relative to vegetative structures like leaves. This study examines the apparancy hypothesis and the resource availability hypothesis using a phylogenetic comparative approach within the genus Cornus. During the 2016 growing season, plants of 25 species of Cornus were tracked for flower and fruit phenology as well as sampled for floral and fruit tissue in a common garden experiment at the Arnold Arboretum of Harvard University. This tissue was used to quantify floral and fruit defensive chemistry (e.g. tannin activity, total phenolics, total flavonoids, titratable acidity), and fruit palatability traits (e.g. water, sugar, lipid, and protein content), and the color of reproductive structure using reflectance spectroscopy. Native habitat environmental data was obtained using digitized herbarium records and publicly available environmental data layers. Trait-trait and trait-environment relationships were assessed with phylogenetic generalized least squares regression. The evolution of later flowering phenology was correlated with increased floral phenolics and tannins, and the evolution of increased fruiting duration was correlated with increased fruit tannins, both supporting the apparancy hypothesis. Additionally, the evolution of higher fruit sugar content was correlated with higher fruit tannins, and a strong evolutionary trade-off between the production of tannins and the production of flavonoids was observed. With respect to habitat, floral and fruit flavonoids and tannins were consistently lower in species native to warmer environments, while fruit phenolics and was higher in drier environments, which may support the resource availability hypothesis.

Show moreNeonatal abstinence syndrome (NAS) in infants presents unique challenges in feeding and weight gain. The unpredictable clinical manifestations associated with the newborns withdrawal from exposure to drugs in utero can lead to costly delays in transition of the infant out of the Neonatal Intensive Care Unit (NICU).The purpose of this review of literature was to explore feeding positions and nutritional intake with the greatest impact on weight gain in infants with neonatal abstinence syndrome (NAS) following delivery. The secondary purpose was to compare the clinical manifestations of infants with NAS that influence nutritional intake and their relationship to length of time and cost of stay in the NICU. A review of literature was performed using multiple databases. Articles focusing on feeding position and nutrition intake were identified for interventions to effectively promote weight gain, while reducing clinical manifestations common in infants with NAS. Articles exploring improved feeding and weight gain in infants with NAS and reduced length of stay in the NICU were also synthesized for cost reductions to the facility. Results from 12 studies comparing various feeding positions that optimized nutrition, and reduced negative clinical manifestations in infants with NAS were synthesized for content relevant to the research questions. Results suggest a relationship between placing infants in the c-position, and side-lying position to reduce sensory stimulation, with reducing clinical manifestations for infants actively experiencing withdrawal symptoms from NAS. Providing chin and cheek support as needed, decreasing eye contact during feeding periods, and providing darker quiet environments all play an important role in allowing infants with NAS to optimize their weight gain. As previously stated, to manage nutritional intake and optimize weight gain, reduction of clinical manifestations through pharmacological and non-pharmacological interventions must be actively incorporated into the infants' plan of care.

Show moreIncome inequality in Florida is higher than in many states and has been getting worse over time. Inequality has been argued as responsible for a wide-ranging array of economic and social problems, including suppression of lower- and middle-income growth, social fragmentation and separatism, urban sprawl, poor health and mental illnesses, violence, and shortened life expectancy. What explains variance in Florida county income inequality as measured by the GINI coefficient? Bivariate and multivariate weighted least square regressions are conducted for the years 2000 and 2016, and for the change between 2000 and 2016. Three variables achieve statistical significance in all three multivariate models: poverty rate and population density have a positive effect as does educational attainment (although that variable is negative in the 2000 model). Income per capita has a statistically significant positive relationship with inequality in the 2000 model and in the change model. Unemployment rate is statistically significant in the 2016 model and in the change model but has a positive association with the GINI index in the former and a negative association in the latter. Several variables were statistically significant in just one model: cost-burdened housing with a positive relationship to inequality and percentage of minorities with a negative relationship in 2016; and county tax rate with a positive association with inequality in the change model. Conclusions are drawn regarding policy that might be implemented to mitigate worsening inequality in the Sunshine State.

Show moreIn the United States, people are encouraged and even coerced by social forces to behave and interact according to rigid social mores that tend to privilege individuals from a specific gender, racial, and class backgrounds. As many theorists have stated, sexual, gender, and racial minorities navigate their lives experiencing oppression at different levels and at the intersections of different systems of inequality. The marginal social location of these identities often results in people re-defining the social meanings through which they construct their social lives. Although much research has been devoted to investigating the different ways in which people resist the dominant social order, research on polyamory is still highly unexplored. According to the studied population, polyamory is a form of ethical non-monogamy that promotes egalitarian relationships among all parties involved. According to Dr. Mimi Shippers, "poly sexualities offers an opportunity to reorient [...] gender and race relations" (2016:4). In this study, I collected data from nine semi-structured interviews that shine light upon how people in polyamorous relationships engage in the reorientation of gender relations. By looking at reported communication strategies between polyamorous individuals, this study found that the social location of marginalized sexual and gender identities fosters a sense of solidarity through which people redefine the meaning in their interactions as they inform people's identity. Nevertheless, these dynamics result in the resistance of some aspects of the dominant social order and the reproduction of others.

Over the course of, and in partial fulfillment for, the degree of Bachelor of Fine Arts in Studio Art and the degree of Bachelor of Fine Arts in Film Production, I have produced a multimedia body of work. I made this body of work as a reflection and result of my processes and studies, and as a method to examine perception, and representation in relation to identity. This body of work combines drawing, painting, printmaking, ceramics, and filmmaking; utilizing each medium to scrutinize language, particularly that of the terms "black" and "white" and their cultural relationships to each other. Through this practice, my work evolved into a study of expectation, as situated through language, and conventional understanding. This work adds to the discourse on spaces and expectations of marginalized communities, art, and continues the tradition of the artists' practice as a form of research. I also position this work in relation to current mass culture iconography while using a distancing effect to explore concepts of martyrdom and minstrelsy as reflections of expectations on my own experience.

Show moreFragile X-associated tremor/ataxia syndrome (FXTAS) is an X-linked late-onset neurodegenerative disorder caused by a noncoding trinucleotide repeat expansion in the FMR1 gene. This gene produces fragile x mental retardation protein (FMRP), an RNA binding protein whose targets are involved in brain development and synaptic plasticity. One of the proposed mechanisms of FXTAS pathogenesis is an RNA gain-of-function in which the repeat expansion causes toxic mRNA that sequesters important proteins in the cell, interfering with their functions. Another suggested method of pathogenesis is through a mutant protein called FMRpolyG. This protein results from repeat-associated non-AUG (RAN) translation, in which the expanded repeats are translated where they otherwise would not be. This protein co-localizes with intranuclear inclusions and nuclear membrane proteins, causing disorganization of the nuclear lamina in FXTAS patient brain samples and neurons differentiated from FXTAS patient-derived induced pluripotent stem cells (iPSCs). iPSC technology involves reprogramming an adult somatic cell back to an embryonic-like state, allowing it to be differentiated into all cell types. A limit with iPSCs, though, is modeling late-onset disorders because the cells lose all age-related features during reprogramming. Progerin, a truncated form of the lamin A protein, has been used to age neurons differentiated from Parkinson Disease (PD) patient-derived iPSCs. Progerin-mediated aging was found to unmask PD-like phenotypes in those neurons, making it a promising technology for modeling late-onset disorders such as FXTAS. In this study, we investigated the link between the aging process and FXTAS pathogenesis in neurons differentiated from FXTAS patient-derived iPSCs with the use of progerin. Progerin transduction was successful in aging the FXTAS neurons. The presence of FMRpolyG was confirmed and an interaction with Lap2b was observed. In some neurons, there was also an observed interaction between FMRpolyG and progerin. Overall, this data suggests that there is an interaction between the mutant FMRpolyG protein and the nuclear membrane during aging, which may contribute to the cell death that causes neurodegeneration in FXTAS patients.

The Strong Black Woman Schema (SBWS) is a cultural expectation placed on black women to unfailingly display signs of strength and caretaker qualities, while suppressing their emotions. The present study aimed to examine the relationship between the SBWS and psychological distress, suicidal behaviors, and resilience. Researchers expected to find a positive relationship between the SBWS and psychological distress, a positive relationship between the SBWS and resilience, and an undefined...
Show moreThe Strong Black Woman Schema (SBWS) is a cultural expectation placed on black women to unfailingly display signs of strength and caretaker qualities, while suppressing their emotions. The present study aimed to examine the relationship between the SBWS and psychological distress, suicidal behaviors, and resilience. Researchers expected to find a positive relationship between the SBWS and psychological distress, a positive relationship between the SBWS and resilience, and an undefined relationship between the SBWS and suicidal behaviors. The study also examined the potential moderating effects of the SBWS and resilience on the existing psychological distress-suicidal behaviors relationship. Lastly, the study examined how socioeconomic status moderates the relationship between the SBWS and psychological distress. It was expected that the SBWS and resilience would weaken the relationship between psychological distress and suicidal behaviors; higher socioeconomic status would weaken the relationship between the SBWS and psychological distress. Researchers recruited 177 black women to take a 30-minute survey. A bivariate correlation analysis showed that the SBWS shares a positive relationship with psychological distress, including depression, anxiety, and stress, and suicidal behaviors. However, resilience was not associated with the SBWS. Resilience was found to moderate the psychological distress-suicidal behaviors relationship, while the SBWS did not. Socioeconomic status did not moderate the relationship between the SBWS and psychological distress. The findings of this study bear important clinical and community implications. By determining the harmful effects of the SBWS, further research can be conducted on how black woman, mental health professionals, and community advocates can mitigate its effects.

Show moreResearch has shown that in Human-Human Interactions kinematic information reveals that competitive and cooperative intentions are perceivable and suggests the existence of a cooperation bias. The present study invokes the same question in a Human-Robot Interaction by investigating the relationship between the acceleration of a virtual robot within a virtual reality environment and the participants perception of the situation being cooperative or competitive by attempting to identify the social cues used for those perceptions. Five trials, which are mirrored, faster acceleration, slower acceleration, varied acceleration with a loss, and varied acceleration with a win, were experienced by the participant; randomized within two groups of five totaling in ten events. Results suggest that when the virtual robot's acceleration pattern were faster than the participant's acceleration the situation was perceived as more competitive. Additionally, results suggest that while the slower acceleration was perceived as more cooperative, the condition was not significantly different from mirrored acceleration. These results may indicate that there may be some kinematic information found in the faster accelerations that invoke stronger competitive perceptions whereas slower accelerations and mirrored acceleration may blend together during perception; furthermore, the models used in the slower acceleration conditions and the mirrored acceleration provide no single identifiable contributor towards perceived cooperativeness possibly due to a similar cooperative bias. These findings are used as a baseline for understanding movements that can be utilized in the design of better social robotic movements. These movements would improve the interactions between humans and these robots, ultimately improving the robot's ability to help during situations.

Show moreVibrio choleraeis the etiological agent of the severe diarrheal disease-cholera and natural inhabitant of estuarine and coastal waters. The proximity of the Florida Indian River Lagoon (IRL) to areas affected by recent cholera outbreaks makes this estuary ideal to investigate the environmental dynamics and their potential role in V. cholerae's pathogen emergence. We identified two locations in the IRL, Feller's House UCF Field Station and Shepard Park, as our collection sites. We collected samples from three different fractions - water, plankton, and sediment - and recorded data for several water parameters such as pH, temperature, and, turbidity. In the laboratory, we enriched samples in alkaline peptone water and isolated V. choleraeusing widely used selective media Thiosulfate-Citrate Bile Salts-sucrose agar (TCBS) and CHROMagar Vibrio. From our study, we isolated 100 potential V. cholerae isolates, which were confirmed using biochemical tests such as oxidase and Kligler's Iron Agar. V. cholerae has allelic variations in the core genes such as ompU, which provide pre-adaptation to virulence. We investigated the allelic variations within ompU to characterize V. cholerae isolates. We elucidated the sequenced allele of ompU and built a neighboring-joining phylogeny tree to view the differentiation among vibrios. Our findings provide insight into the endemic population of V. cholerae in the Eastern Coast of Florida. Further studies include a screen for additional virulence genes and investigate the role of environmental dynamics on the distribution of V. cholerae and emergence as a human pathogen.

Show moreThe belief that intentions are hidden away in the minds of individuals has been circulating for many years. Theories of indirect perception, such as the Theory of Mind, have since been developed to help explain this phenomenon. Conversely, research in the field of human kinematics and event perception have also given rise to theories of direct perception. The purpose of the study was to determine if intentionality can be directly perceived rather than requiring inferential processes. Prior research regarding kinematics of cooperative and competitive movements have pointed toward direct perception, demonstrating participants can accurately judge a movement as cooperative or competitive by simply observing point-light displays of the isolated arm movements. Considering competitive movements are often performed faster than cooperative movements, speed was perturbed for the purpose of this study to determine if participants are relying on cues or if they can indeed perceive a unique kinematic pattern that corresponds to intentionality. Judging the clips correctly despite perturbation would suggest perception is direct. Additionally, we hypothesized judgments accuracy would be higher in the presence of two actors pointing to the use of interpersonal affordances. Twenty-eight participants from the University of Central Florida were asked to judge 40 clips presented in random order including: normal or perturbed competitive actions with one or two actors; normal or perturbed cooperative actions with one or two actors. Percent correct and reaction time data were analyzed on SPSS using a repeated measures ANOVA. Results rejected the hypothesis that social perception is direct and supported indirect perception, indicating participants relied on cues to make judgments, and provided potential support for the interpersonal affordance hypothesis.

Show moreHeterogeneous consumers make the decision to buy a durable good or to download a replica, and a monopolist chooses to price and protect their intellectual property in the form of an authentication cost. An optimal price and authentication cost is derived, and shown to be higher than the efficient outcome for a uniform distribution of consumers. The optimal selection of price and protection are shown to be commensurate with his authenticating technology, and the searching ability of consumers. As an extension, a layout for a monopolist problem where consumers have different searching abilities is shown to be indistinct from a homogeneous case when consumers are uniformly distributed.
