Carbon nanotubes (CNTs) have been demonstrated to possess uniquely valuable electronic properties, good chemical stability, and large surface area. Potential applications include advanced catalytic systems to electrochemical sensors, and highly efficient fuel cells. With an increased interest in flexible/bendable electronics, the need for flexible energy storage devices to work within these devices has grown.

Show moreCarbon nanotubes (CNTs) have been demonstrated to possess uniquely valuable electronic properties, good chemical stability, and large surface area. Potential applications include advanced catalytic systems to electrochemical sensors, and highly efficient fuel cells. With an increased interest in flexible/bendable electronics, the need for flexible energy storage devices to work within these devices has grown. Carbon nanotubes have a small diameter, high surface area, and have a graphitic structure. Along with their unique properties, it is also their ability to support metal nanoparticles that their application in flexible energy storage applications is actively being studied. The zinc carbon battery was used as a template for these new flexible batteries, with zinc (Zn) working as the anode active material and manganese (IV) oxide (MnO2) serving as the cathode active material. At the center of this research is the addition of CNTs into the battery design. The CNTs high strength and flexibility make them a promising component for thin and flexible batteries and electrodes. The focus of this study is to show how the development of carbon nanotube based materials has rapidly changed in recent years. My work starts with the inclusion of CNTs into tradition assemblies such as the synthesis of functional cross-linked multi-walled carbon nanotube paper films but with nanoparticles incorporated into the cross-linked network. The project then began to focus on the creation of coin cell (button cell) and flexible batteries using the cross-linked carbon nanotube film with manganese (IV) oxide, zinc foil and an electrolytic solution to replicate the electrochemistry of a zinc carbon battery. Cross-linking carbon nanotubes is difficult because of the low degree of surface functionalization which would be used to connect the tubes, so a better way to incorporate the carbon nanotubes into a functional composite was required to move the field of carbon nanotube out of a plateau. The advent of consumer 3D printing with thermoplastics provided a unique opportunity to mix carbon nanotubes with the thermoplastics and eventually photopolymer resins to produce a new class of functional 3D printing materials which are described in this thesis.

Show moreA Letter to the Audience Before I draw the curtain and release the philosophical coddiwomple that follows, I would like to take this time to reflect on its coming to be and, hopefully, explain myself to the audience. A preemptive rundown and a warning (or two) of what this project is meant to be--and why I've chosen to write it in this way--will be helpful in understanding what’s going on. To start, I’d like to ward off any high expectations for traditional order or strict structure to my creative project: I make no claim to the exactness or completeness to the words written here. Of course I suppose my argument could have been made by writing a regular paper, and probably with less words at that, and, to justify this piece of thoughtful whimsy, I’ll start by answering this obvious question that the reader might find themselves asking--why didn't I? It's a fair question. There are so many ways I would like to address this question, but I’ll try to constrain myself to the most topical. First, in the most blunt way: I've get lyrically restless writing philosophy in the prescribed formats and sometimes adhering to strict contextual expectations can restrict the writer on a thoughtful quest. I long for the days when philosophers were allowed a bit of creative freedom in getting their thoughts out there; mostly relying on their own thinking and just writing it in the way they wanted. I feel restrained by rules of philosophical writing, at times, and I think this subject beckons for me to stretch my imagination and ignore (for the moment) the need to follow a certain path of inquiry. This reason, for the unorthodox method that I take, address the less than straightforward way I go about putting forth my case: lives are not straightforward. Nothing about by subject is straightforward. Our lives, conduct and even characters are barely legible to us. Once more, our thoughts are not like he standard philosophical paper--not really. Academic papers (strictly academic) are crafted y stepping outside oneself to edit. Our thoughts do not chug along like a train down one track, at least mine do not. It's more like flying a kite. I have this idea, storytelling as the art of living, and I release it letting the thought mingle with my other beliefs, desires, and goals. The control I have the kite is minimal, just a flimsy piece of plastic and a big of string. Every once in a while a gust of whimsy blows by and takes my kid away, then, I have to slowly gain back control by guiding into a better position. As the reader will experience in the arupt way in which conversations end and begin. It will help to see this piece as the writing process of what would be philosophy paper, refined for presentation. I wanted to represent this attitude in the setting of the lay, thus, I set my scene within the mind of a student reading Aristotle with my interlocutors being character manifestations of our student's different perspectives. Her multitudes, if you will, come together to interpret Aristotle's lesson for living well as a lesson in writing well; with one of them further arguing that his lesson is taught to convince us that is self-authorship is what makes a life well lived. As our student reads the relevant passages from Aristotle, lachessi presents her authorial analogy to the group: showing how authorship is practical wisdom and how this take on wisdom better informs us as to what happy people are doing. After Which the collective discusses Lachesis Second claim, that, Aristotle is telling us to become the author of our own stories. Finding the form that best fit the matter at hand is not an easy task; I struggled to find an appropriate vessel for discussion the art of living as the art of storytelling. I needed a narrative form, that relies on heavy dialogue, and one that would allow for me to incorporate quotes from the nicomachean ethics in a way that wouldn't interrupt the flow. I, also, wanted a writing style that could allow be to sway a bit from the course, in a relevant manner. A stage play is the practical choice for m project mostly because of its dialog aspect; and the organization's of acts and scene help to keep the dialogues as individual conversations that go together, yet, do not exactly merge seamlessly from topic to topic. This type allows me to connect Aristotle's Phronimos to the well written author and discuss how she embodies the notion of authoring her one's own life.

Show moreThis current study explores how millennials’ online perceptions are affecting their employment opportunities. Living in this digital age, all young adults and college students should be conscious of their online perception. This study exposes more information on what employers and recruiters do not want to see while screening a potential candidate’s social media. It will test the effects of a created social media user engaging in inappropriate images of sexual content and illegal drug use. This study focuses on how images related to sexual content and illegal drug use can impact one’s credibility and employment opportunities. After all, public perception is reality and if that reality has the potential to hurt an organization’s reputation, the potential candidate probably won’t be offered a position.

Show moreThis case study examined Thomasville, Georgia--a seemingly quiet southern town with a history that speaks volumes. After the Civil War, Thomasville went for broke and broke the mold in the 1870s, popularizing itself as a health resort for pulmonary patients in the North. By the 1890s, Old South cotton plantations transformed into northern-owned hunting plantations, retaining the plantation title and the black labor force. While these changes seemed to occur naturally, New South engineers anticipated the town's success as the result of efforts put forth by one Confederate-steeped family and a black workforce dedicated to supporting the needs of visiting northerners. White northerners and black southerners performed a recitation of plantation life that emulated the Old South and reinforced toxic labor patterns. Home to roughly seventy plantations today, Thomasvillians literally live in the past but shroud themselves in their progressive rhetoric. The skeleton of the physical and social infrastructures, built to maintain this idyllic state, still remains and provides evidence of disparity that undermines the progress Thomasville purports to project.

Show moreMaternal separation in rats is used to study how stress impacts the brain. Our laboratory previously made use of a simple model of learning and memory to assess the effects of early stress in the form of daily maternal separation on adult learning and memory using a simple model system to assess learning and memory: eyeblink conditioning. Glucocorticoids are important for modulation of stress for adult learning and memory. Previously we found that neonatal stress increased glucocorticoid receptor expression in the cerebellum, that increased receptor expression was correlated with impaired learning and that blocking excess receptors restored normal learning. Here we set out to begin assessing the possibility that more complex learning and memory brain systems may be altered in a similar way. The parietal hippocampal network has been shown to be part of the brain network responsible for learning, memory and spatial navigation and has not been previously assessed following neonatal stress. To test for how early stress affects learning and memory in the parietal hippocampal network, GR expression was quantified. By using previously obtained coronal sections of brain data, GR expression was analyzed in the parietal cortex. Neonatal maternal separation was found to not significantly alter GR expression in the parietal cortex or effect stress on the parietal hippocampal network. GR expression varies oppositely from studies on connectivity and differences in regional GR expression is suggested to not interact with neonatal stress.

For three years, this group of internees survived internment together and successfully developed a functioning internment camp community. The internees developed genuine friendships with one of their Japanese commandants, Rokuro Tomibe because he did everything in his power to make life more comfortable for them, and to understand their cultural differences. After their liberation by American forces in February 1945, the internees dispersed. However, for decades afterward, the Baguio internees continued to reunite with one another, and even with Tomibe. These reunions were a testament to the strength of the community and friendships they had developed through internment.

This study attempts to understand the daily fluctuations of picoplanktonic organisms in relation to the abiotic and biotic factors that may influence their dynamics by 1) analyzing the fluctuations in picoplankton community structure and density from 8am to 8pm 2) analyzing the relationship between picoplankton fluctuations and abiotic factors including light, temperature, and the tidal cycle and 3) analyzing the impact of a sponge filter feeder on picoplankton abundance. Picoplankton densities fluctuated significantly through out the day and tidal cycles and vertical mixing could play a large role in these daily dynamics. Sponge feeding can significantly decrease the density of autotrophic picoplankton and could be a form of control for picoplankton communities.

Show moreNeuron glial antigen 2 (NG2) is a transmembrane protein predominately expressed in certain central nervous system (CNS) cells. Among these cell types are oligodendrocyte precursor cells (OPCs) and astrocytes. The 250 kilodalton core protein undergoes extensive post-translational modification. The addition of chondroitin sulfate glycosaminoglycan chains and disulfide bonds allows for binding to a number of receptors and extracellular ligands which allows it to play a vital role in cell migration, survival, and angiogenesis. Although NG2 expression has been classically associated with CNS cell types, the presence of NG2 has been detected in immune cells in a variety of CNS pathologies. Following a spinal cord injury (SCI), a small population of bone marrow-derived macrophages (BMDMs) infiltrating the injured spinal cord have been reported to express NG2. While infiltrating macrophages in the injured spinal cord are considered pro-inflammatory, it is unclear whether NG2+ BMDMs are classically (pro-inflammatory) or alternatively activated (anti-inflammatory). In addition, much is still unknown regarding the immunological role of NG2+ macrophages. To determine the factors driving NG2 expression, we quantified protein expression following various activating stimuli. The findings suggest that NG2 upregulation is strongly associated with alternative (anti-inflammatory) activation.

Show moreUndergraduate music students receive the greatest amount of instruction in their applied lessons; however, the amount of research regarding teaching in the private lesson setting is much less than that of the classroom setting. Research regarding pedagogy and highly effective individuals or master teachers is common. American saxophone teachers have been studied considerably with the exception of teachers who studied with Sigurd Raschèr, one of the saxophone’s earliest pioneers within the classical tradition. This study aims to add to the body of research on applied teaching as well as saxophonists who have studied with the master teacher Sigurd Raschèr. The purpose of this study is to analyze and describe the similarities and differences in educating saxophonists between two prominent teachers from diverse American traditions. The two teachers selected for the study were Patrick Meighan who recently retired from Florida State University and Eric Nestler who currently teaches at the University of North Texas. Both participants answered ten questions regarding teaching techniques, concepts, and values. The study found that the participants received instruction from teachers of diverse traditions. The strongest influence for Meighan and Nestler were the teachers with whom they spent the most time. Over time, Meighan and Nestler developed their own unique teaching practices through an amalgamation of their teachers and individual experiences. The results of the study suggest that master teachers follow a pattern of learning one school of thought, imitating their teacher, and developing their own unique school of thought. The appendices include transcriptions of the participants’ answers.

However, it is unclear whether nutrients delivered to the Gulf of Mexico are subsequently exported from the Gulf, further influencing the chemistry of the North Atlantic. The nitrogen and oxygen isotopic composition of nitrate (NO3-) have been increasingly used to track nitrogen fluxes to, from, and cycling within the ocean. Here, we report the first dual isotopic composition measurements of NO3- from the Gulf of Mexico and Florida Straits, and compare these with prior measurements from the South and North Atlantic, and identify potential processes consistent with the observed shifts. The nitrogen and oxygen isotopic composition of nitrate in the Gulf of Mexico and Florida Straits is very similar to that previously measured in the Sargasso Sea. There is little evidence for riverine or submarine groundwater NO3- directly influencing the isotopic composition of NO3- exported from the Gulf of Mexico. These results are consistent with recent modeling work suggesting that the majority of riverine nutrients delivered to the Gulf of Mexico are retained in the near-shore region.

Show moreCardiovascular disease is the leading cause of death worldwide, and the incidence of these diseases increases with age. Senescence is an aging process that results in the termination of cell proliferation due to multiple cell divisions that shorten telomeres and damage DNA. Senescence can also be induced prematurely by cellular stress including reactive oxygen species (ROS), produced by several sources including nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (Nox) enzymes. Excessive production of cellular ROS is maintained by antioxidant enzymes including superoxide dismutase (SOD) 1 and 2 and catalase. Published data from our lab showed that blackberry polyphenols increase SOD1 expression and decrease expression of Nox1, decreasing ROS levels and reducing senescence in vitro in vascular smooth muscle cells (VSMCs). Through the use of ApoE-/- male mice, preliminary data show that supplementation with 2% freeze-dried blackberry powder reduced senescence and plaque in response to high fat diet in the aorta. However, it is unknown whether the protective effect of blackberry is mediated by downregulation of Nox1 in vivo and whether this effect is also observed in female mice. In this dissertation, we will test the hypothesis that the protective effect of blackberry supplementation in reducing senescence and atherosclerosis is associated with the downregulation of Nox1 in vivo in both male and female ApoE-/- mice. After 5 weeks of treatment with low fat (LFD), high fat (HFD), or HFD supplemented with blackberry (HFD+BL), results showed that blackberry reduces Nox1 expression in male aortas. Blackberry further protects against ROS production by reducing activation of Angiotensin II (Ang II) targets including p38 mitogen activated protein kinase (MAPK), extracellular signal-regulated kinase (ERK), and peroxisome proliferator-activated receptor coactivator-1 (PGC-1a). In female aortas, blackberry upregulates antioxidant enzyme SOD2.

Show moreTraditional methods of lie detection (e.g., polygraph, GSR, heart rate) have often led to more controversy than successful detection. Leading the charge into the future of lie detection technology is eye-tracking, a young and innovative field that represents a new and promising strategy for addressing deception by measuring eye movements, pupil size, and attentional allocation. This experiment examined the body’s physiological reactions to engaging in deception by using pupillometry. We examined and compared these physiological responses between two conditions: being told to tell a lie or the truth. We also examined the effects of the lie being told spontaneously compared to knowing in advance that a lie would be produced, as well as the effect of practice. With the use of a rapid serial visual presentation (RSVP) paradigm, participants looked at a continuous stream of visual images (i.e., letters) and were asked to report (or lie about) the letter of a unique color (black letter among gray letters). Participants were prompted at the end of the trial to either report the letter correctly, or to lie about it. On some trials, this prompt occurred in advance of the letter stream so participants could prepare to lie, and for other trials it occurred at the end and participants had little opportunity to prepare their lie. It was predicted that lies would be characterized by an increase in pupil size, but this prediction received limited support. With regard to reaction time, lie responses took significantly longer, and there was a trend for this cost to decrease with practice. So while lies were successfully detected, the implementation of pupillometry was not successful, and future research is suggested in order to collect more powerful results from a stronger paradigm.

Show moreThe media in the United States (U.S.) continues to expand its broad reaching coverage which shapes national discourse and perceptions about crime. Thus, it becomes increasingly important to assess the information that is being produced and disseminated through this medium. The purpose of the current research is to employ a content analysis of four widely circulated news sources, The New York Times (NYT), The Wall Street Journal (WSJ), The Washington Post, and USA Today, within the years 1987, 2005, and 2015 to assess the variability in media coverage and how the discussion of drugs and drug usage in these news sources has changed over time. This research focuses specific attention on whether the coverage changed, in part, as a result of the demographic shift in drug usage or some other bias process. This research seeks to shed light on implicit bias that underlies the news coverage as well as the policy responses to the drug problem in the U.S. In the analyses, four major themes emerged: criminality and social control, descriptions of treatment and rehabilitation, race and racial subtext, and policy. As hypothesized, there is a substantial decrease in the discussion of criminal justice responses to opioid use compared to methamphetamine (meth) and crack use. In addition, treatment was increasingly more likely to be discussed as time progressed, which suggest that this discussion was most common during the opioid crisis. Additionally, race seemed to play a large role within each time period as there were high counts of racial subtexts over all three time periods. Black Americans were labeled using low socioeconomic and criminal/violent descriptions, and White Americans were described as having higher potentials and access to resources. Finally, as policies shifted over these three time periods, so did the media coverage. The discussion within the meth epidemic is broader and contains slightly more personal stories, and the opioid crisis contained the highest number of individual stories connected with policy implementation. The results of this study highlight the relevance of the media and how they can control the conversation about major social ills in society. Thus, it is critical to understand how the media constructs narratives about social problems, and it is important for the media to recognize how the biases in its coverage can impact society at large. Overall, the significant shifts in media conversation about drugs can influence bias among readers. Society absorbs media messages regularly and will commonly use the media to form opinions about hot topics or relevant topics within the news. This study calls for news sources to recognize implicit biases and understand the impact of the way news is covered.

Show moreAppearing in early to late childhood, Attention Deficit/Hyperactivity Disorder is one of the most common psychological disorders and can affect several aspects of a child’s life, including peer relations and overall well-being. Key symptoms of ADHD include symptoms restlessness, inattention, hyperactivity, and impulsivity. There is a high comorbidity between ADHD and anxiety, although it is not clear which disorder comes first developmentally since possible mechanisms that underlie the link between them are not well understood. Some studies have suggested that specific parenting styles may be linked to both ADHD and anxiety in young children. These studies have suggested that the symptoms of ADHD may lead to controlling or overprotective parenting - including intrusiveness and discouragement of personal independence. This parenting style has been linked to increased anxiety levels in children and could be a potential catalyst for increased levels of anxiety among children with ADHD. The current project aimed to examine whether the comorbidity between anxiety and ADHD could be connected to over-protective parenting by testing a mediation model in a group of 102 5-7 year old children. We utilized the Child Behavior Checklist (CBCL) to measure the level of ADHD and anxiety symptoms as reported by the parent and the Parenting Styles and Dimensions Questionnaire (PSDQ) to measure the overprotective tendencies exhibited by the parent. Results supported a mediation model wherein the link between ADHD and anxiety symptoms was significantly mediated by over-protective parenting style.

Show moreHypoxia has been known to influence drastic changes in an organism at a molecular level. New studies are constantly unveiling new information about how organisms respond to hypoxic condition, but the mechanism in which these organisms do so is complex and remains undetermined. In this study, a full transcriptome analysis of maize (Zea mays) apical meristem tissue was conducted under hypoxic conditions by utilizing RNA-seq. The transcriptomic data received from various time points over the duration of 18 hours of hypoxia provided valuable information about the transcriptional response of hypoxic responsive genes over time. These data prompted a deeper probe into the short-term response at the 2 hour mark. An additional RNA-seq protocol was carried out after 2 hours of flood-induced hypoxia. Intensified expression levels were found in the known hypoxic responsive genes pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH). Induced transcription was observed in the rice (Oryza sativa japonica) ortholog (Zm00001d023859), which is known for ethylene-induced aerenchyma formation in roots under oxygen deficient conditions in rice. Moreover the rice ortholog (Zm00001d022084) also displayed up-regulation in gene expression compared to the control. This gene is implicated flooding tolerance during seed germination and early seedling growth in rice but is minimally annotated in maize. Induction was achieved in other hypoxia responsive genes, but not nearly to the same degree. It was thus concluded that 2 hours is an important transition period for the inbred maize line B73 to reach optimal response to hypoxia. It is hoped that this data can be used to unveil the chromatin dynamics behind this hypoxic stress response.

Currently, the industry of genome engineering is in dire need of a fast, efficient, and highly specific Cas9 protein to use in larger genomes and to prevent off-targeting activity within cells. Here, I will discuss our effort to design novel variants of a thermophilic CRISPR protein called, "AceCas9." We utilized methods of directed evolution to introduce modifications in the wildtype AceCas9 protein's structure. We tested these variants and the wildtype protein in experiments to better understand and search for 1) An efficient AceCas9 and 2) A specific AceCas9.

Show moreKaposi sarcoma is a type of lymphatic and skin cancer that is caused by Kaposi Sarcoma-associated virus (KSHV). KSHV ORF45 is classified as an immediate early gene that has multifunctional roles. One of its major functions is to activate the extracellular signal-regulated kinase (ERK) and p90 ribosomal kinase 1 and 2 (RSK1/2) in the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway. It has been discovered that KSHV ORF45 can activate both the ERK and RSK which promote the reactivation of KSHV. There is limited evidence that observes the behavior of all KSHV ORF45 homologs. Therefore, we are interested in studying the functional conservativeness within gammaherpesvirus ORF45 subfamily, including the ability of ORF45 homologues to activate ERK and RSK, and the colonigenesis of HeLa cells transfected with ORF45 homologues. In this study, we found that amongst all ORF45 homologues, there is strong conservation in the amino-terminus, ERK, RSK and ORF33 binding sites. We examined that there are different levels of phosphorylated RSK and ERK amongst the gammaherpesvirus homologues. In addition, we examined that G418 selection of different ORF45 homologues. The result showed no significant difference between the gammaherpesvirus-2 subgroups (Rhadinovirus, Macavirus, and Percavirus).

Show moreThe Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated (CRISPR-Cas) systems utilize Cas proteins and CRISPR RNA (crRNA) to cleave target DNA. The crRNA are responsible for guiding the Cas enzyme to the target DNA sequences whereas the Cas enzyme cleaves the target. Cas9 is one of the most intensively studied CRISPR-Cas systems owing to its potentials for genome editing and clinical applications. To be cleaved by Cas9, the target substrate must have an about 20-nucleotide long protospacer region which is complementary to the guide region of the crRNA, and a protospacer adjacent motif (PAM) that is recognized and bound by the PAM-interacting domain (PID) of Cas9. Opposed to the most commonly characterized Streptococcus pyogenes Cas9 protein, which optimally utilizes a 20-nt long sgRNA, AceCas9, from organism Acidothermus cellulolycticus, reaches most optimal cleavage activity utilizing a 24-nt long sgRNA, at 50°C. Further various assays reveal that the PID within AceCas9 is possibly involved in substrate specificity and off-target cleavage. Based off in vivo survival assays, we hypothesized that, in addition to PAM recognition and binding, the PID is also involved in AceCas9 substrate specificity. After kinetic studies, varying cleavage rates of AceCas9 PID variants supports that the PID is somewhat responsible for off-target activity, but to what extent is still not understood. The continued characterization of various types of Cas9s will lead to a broadened selection of Cas9s while also improving the proteins application within biomedical research with a greater understanding of Cas9 specificity.

Show moreThis thesis aimed to provide insight into the process students go through in their effort to understand conservation of mechanical energy in an undergraduate studio physics classroom. The data collected includes a transcript of the conversations a group had while working through a lab that asked students to plot potential and kinetic energies versus time of a bouncing kick ball over the course of 3 bounces, the lab reports of 3 groups from said lab, and all of those group members' Force Concept Inventory and Energy and Momentum Concept Survey pre- and post-tests. The transcript proved most useful in pointing out common starting points in student reasoning, showing what ideas students begin a lab with before they make sense of it all by the end. The most confounding issues that students seemed to have came when a second dimension of motion was added to scenarios (i.e. thinking about a ball rolling down a ramp instead of just bouncing straight up and down). Unfortunately there was not enough evidence for me to make claim about why this second dimension is more of a problem for students, only that this remained an issue for them from the beginning to the end of the semester.

Show moreFor many Americans in the modern digital age, the media is our primary source of information on current events and politics. Whether it be social media, television, online publications, newspapers, radio, or other forms of mass media, these platforms offer much of the information we absorb about the world around us. By guaranteeing freedom of the press, the First Amendment provides protections for the media and affords these platforms extensive freedoms regarding the news they publish by guaranteeing freedom of the press. Hence, these platforms have no formal obligation to produce ‘unbiased’ content or discourse which simply states the facts without distorting the truth, using emotionally-charged language, or presenting information in a way that promotes or diminishes relevant ideologies. For the sake of this project, I will solely explore media bias as it arises in ‘the news’, which I am defining here as any written, visual, or verbal broadcasts which convey information to their audiences about current events in regional, national, or international affairs. Generally, news networks aim to inform to their audiences, though the objectivity of such information is not always a factor.

Florida State University houses human skeletal remains from four sites in St. Augustine, Florida (8SA36-7, 8SA7-6, B28L1and B42L1) which were originally excavated and analyzed in the 1970s. This study uses current techniques to revisit previously examined skeletal material. Estimations of sex, age at death, and stature were reassessed, and new body mass estimations were added. The current labeling of the material from three of the sites differed drastically from the labeling described in the previous analyses. This issue created challenges when trying to compare current finding to those of the previous assessments. However, this analysis yielded significantly different results from previous assessments when assigning sex, while concluding average age and stature estimates similar to previous assessments. Additionally, an updated and shareable digital catalogue, an inventory of materials, and collection of field notes and previous research reports were created. This project adds to established data and serves as a method of conservation of information associated with four St. Augustine archaeological sites.

The purpose of this research is to examine the prevalence of barriers to campus health care services encountered by young LGBTQ+ students at a major southern university. Another goal was to provide guidance for health care services in making these spaces more accessible to this vulnerable population. Our sample consisted of 56 LGBTQ+ college-aged participants. While students were generally utilizing the healthcare services provided to them on campus (74% reported using campus services), many faced concerns about disclosure of sexual or gender identity to health care providers and expressed discomfort utilizing services in general. Going forward, we suggest that university health care services provide clearer gender and sexual identity markers in their communications and medical documents to provide a more inclusive and stress-free environment. We also suggest policy changes such as changing the name of the Women’s Clinic to be more inclusive and providing more outreach to the LGBTQ+ student community.

Show moreOrganizations today searching for new ways to develop a more prolific work environment often take into consideration both employee productivity and well-being. Research on work-life balance suggests that separating work from other daily activities can be beneficial for both productivity and well-being, but modern technological innovations have blurred this line between a work and social life. The shift to a 24/7 work environment has led to various studies searching for ways technology is affecting psychological health and the work environment itself. Past research suggests that cell phones impair academic performance, but effectively managing cell phone use may provide a channel for a better work-life fusion. Based on previous research, I predict that restricting the use of cell phones in classrooms may negatively affect academic performance. Additionally, this restriction may affect current mood, specifically increasing negative affect, with also increased levels of anxiety. If so, this would suggest that administrators may need to adjust their management of technology strategies in the classroom and subsequently the workplace.

In Experiment 1, data from 337 adults (ages 20-73) were collected. Participants completed a survey asking them how much time they would be willing to invest in daily brain training to extend their functional independence by certain amounts of time (e.g., 1 month, 1 year). Participants also completed surveys assessing self-perceived health and cognitive functioning, personality, technology experience, and demographic variables. Even for relatively small gains (extending functional independence 1 week), participants reported being willing to dedicate an average of 11.5 minutes (SD = 19) every day to brain training, with some participants reporting being willing to play for significantly longer. The best predictor of willingness to invest time into brain training was belief in brain training efficacy, β = .36, t(330) = 7.75, p < .001. There was also a positive association between self-perceptions of cognitive deficits and willingness to engage in brain training, β = .10, t(330) = 2.00, p < .05. Experiment 2 was much smaller (N = 29, all older adults), and thus could not effectively explore individual differences. However, it was found that participants were willing to invest a large amount of time for relatively small gains. Results indicate that individuals are willing to invest a significant amount of time each day playing brain games to remain in their own homes and be independent longer. However, intention to engage in daily brain training was influenced by the perceived amount of benefit and self-perceived cognitive deficits. This has implications for predicting the adoption of, and adherence to, potentially effective treatments for cognitive decline.

Show moreDespite near scientific consensus that Earth is warming, much of the general public remains unwilling to acknowledge the reality of climate change. This striking mismatch suggests that the scientific community could improve the clarity and persuasiveness of its message. The current work draws upon two psychological theories in an attempt to increase the success of proenvironmental appeals regarding climate change. Moral foundations theory suggests that liberals respond best to messages framed in terms of harm and fairness, whereas conservatives respond best to messages framed in terms of ingroup loyalty, respect for authority, and purity. Meanwhile, construal level theory suggests that people may find arguments more persuasive when they are relayed in specific, concrete terms rather than general, abstract terms. We combined these theories by presenting liberal and conservative participants with climate change messages framed in abstract or concrete terms, and based in either harm and fairness or ingroup loyalty, respect for authority, and purity. We then assessed relevant proenvironmental intentions and beliefs. Overall, liberals scored higher than conservatives on these attitudes, and this measure was positively correlated with moral concerns about harm and fairness and negatively correlated with moral concerns about purity. However, the manipulations did not significantly impact our results. Together, these findings suggest that framing messages through this technique may not systematically influence proenvironmental attitudes.

Show moreThe Southern Ocean is central to the global climate and the global carbon cycle, and to the climate's response to increasing levels of atmospheric greenhouse gases, as it ventilates a large fraction of the global ocean volume. Global coupled climate models and earth system models, however, vary widely in their simulations of the Southern Ocean and its role in, and response to, the ongoing anthropogenic trend. Due to the region's complex water-mass structure and dynamics, Southern Ocean carbon and heat uptake depend on a combination of winds, eddies, mixing, buoyancy fluxes, and topography. Observationally based metrics are critical for discerning processes and mechanisms, and for validating and comparing climate and earth system models. New observations and understanding have allowed for progress in the creation of observationally based data/model metrics for the Southern Ocean. Metrics presented here provide a means to assess multiple simulations relative to the best available observations and observational products. Climate models that perform better according to these metrics also better simulate the uptake of heat and carbon by the Southern Ocean. This report is not strictly an intercomparison, but rather a distillation of key metrics that can reliably quantify the "accuracy" of a simulation against observed, or at least observable, quantities. One overall goal is to recommend standardization of observationally based benchmarks that the modeling community should aspire to meet in order to reduce uncertainties in climate projections, and especially uncertainties related to oceanic heat and carbon uptake. Plain Language Summary Observationally based metrics are essential for the standardized evaluation of climate and earth system models, and for reducing the uncertainty associated with future projections by those models.

Mutations in the human Cnn gene are associated with an inherited developmental syndrome called autosomal recessive primary microcephaly (MCPH). Cnn mutant Drosophila were used as a model in order to examine the genetic basis of the disorder. Through preliminary screening of the mutant, we discovered that genes regulating metabolism augmented the affects of Cnn, making these mutants susceptible to starvation sensitivity. Additionally, a forward genetic screen revealed mutations that were synthetic lethal with Cnn and we subsequently tested them for starvation sensitivity. Our goal was to identify which other genes regulate metabolism in the Cnn genetic network. One mutation that fulfilled criteria for starvation sensitivity was mapped to a gene that encodes a microtubule-based motor protein involved in transportation and spindle formation. Likely, this candidate shares a microtubule-based function with Cnn. My project investigated whether these mutants are defective in the regulation of metabolism and microtubule assembly in mitosis, and will contribute to our understanding the genetics of the disease pathway of MCPH.

Show moreThis thesis, as part of the international research consortium “ManyBabies”, aims to identify differences in the effect sizes of infant speech preferences based on data cleaning practices and the potential confounding variables of gender, trial order, and participant age. These questions are of interest specifically in the context of study replication, particularly if these factors could explain some of the issues there are with replicating developmental psychology studies. It was thought that infant-directed speech (IDS) clips would have significantly longer screen looking times than adult-directed speech (ADS) clips, and that these effects would be significantly impacted by trial number and the participant age, but less so by gender. The experiment was conducted using an eyetracking paradigm where IDS and ADS audio clips were presented in one of four trial orders. Results found that there was a significant effect of trial type on mean looking time (p < .001) with IDS trials looked at longer than ADS trials. The variables of gender and trial order also had significant effects on looking time across all four conditions. Participant age did not have a significant effect on looking time until participants younger than 365 days were compared with those older than 365 days, where it was found older participants had significantly longer looking time for adult-directed speech trials than younger participants. These findings can be used to formulate better practices for study replication to ensure that potential confounding variables are accounted for; common data cleaning practices were also not found to have a significant influence on effect significance.
