Show moreThe widely known vocabulary gap between health consumers and healthcare professionals hinders information seeking and health dialogue of consumers on end-user health applications. The Open Access and Collaborative Consumer Health Vocabulary (OAC CHV), which contains health-related terms used by lay consumers, has been created to bridge such a gap. Specifically, the OAC CHV facilitates consumers' health information retrieval by enabling consumer-facing health applications to translate between professional language and consumer friendly language. To keep up with the constantly evolving medical knowledge and language use, new terms need to be identified and added to the OAC CHV. User-generated content on social media, including social question and answer (social Q&A) sites, afford us an enormous opportunity in mining consumer health terms. Existing methods of identifying new consumer terms from text typically use ad-hoc lexical syntactic patterns and human review. Our study extends an existing method by extracting n-grams from a social Q&A textual corpus and representing them with a rich set of contextual and syntactic features. Using K-means clustering, our method, simiTerm, was able to identify terms that are both contextually and syntactically similar to the existing OAC CHV terms. We tested our method on social Q&A corpora on two disease domains: diabetes and cancer. Our method outperformed three baseline ranking methods. A post-hoc qualitative evaluation by human experts further validated that our method can effectively identify meaningful new consumer terms on social Q&A. (C) 2017 Elsevier Inc. All rights reserved.

Show moreUnderstanding predictors of early aggressive behavior is necessary to establishing intervention and prevention efforts to improve long-term outcomes for elementary children and their families. This study expands on existing aggression research by examining specific factors in Childhood aggression and their effect on academic performance. We asked 392 parents of 8-12 year olds to answer a 20-minute survey on-line about their children’s behavior, parenting styles, family demographics and grades. We compared demographic information, the occurrence of inattentive/hyperactive symptoms, parental involvement, and inconsistent parenting with 2 forms of aggression, proactive and reactive. These factors and their interactions with each other were compared with academic achievement. In the analysis of proactive aggression, we found that inattentive/hyperactive symptoms (β = .10, p = .01), positive involvement (β = -.11, p = .001), and inconsistent monitoring and discipline (β = .63, p < .001) were all significant predictors of proactive aggression, but income-to-needs ratio was not a significant indicator of proactive aggression (p = .09). We found Reactive aggression to be strongly associated with inattentive/hyperactive symptoms (β = .31, p < .001) and inconsistent parenting and monitoring (β = .50, p < .001), but not parental involvement (p = .46). Interestingly, Parent/child demographics remained insignificant with the exception of ethnicity. Hispanic children had lower rates of reactive aggression than non-Hispanic children (β = -.09, p = .02). We found that children’s grades were correlated positively with Parental education (β = .13, p = .009). Higher levels of inattentive/hyperactive symptoms (β = -.34, p < .001) and reactive aggression (β = -.20, p = .04) predicted lower grades over and above parental involvement. This research contributes to our understanding of the effects of demographic and parenting factors on both proactive and reactive aggression in children.

Diet-induced obesity (DIO) decreases the number of olfactory sensory neurons (OSNs) in the nose and reduces their projections to the olfactory bulb. Whether surviving OSNs have equivalent odor responsivity is unknown. We utilized c-fos immediate early gene expression as a marker for neuronal activation to determine if DIO affects sensory function.

Show moreDiet-induced obesity (DIO) decreases the number of olfactory sensory neurons (OSNs) in the nose and reduces their projections to the olfactory bulb. Whether surviving OSNs have equivalent odor responsivity is unknown. We utilized c-fos immediate early gene expression as a marker for neuronal activation to determine if DIO affects sensory function. Male mice that contained a gfp reporter for the M72 odorant receptor were challenged with control food (CF), moderately-high fat (MHF) diet, or high fat (HF) diet for 6 months upon weaning. Mice maintained on the modified diets weighed significantly more (one-way ANOVA, p<0.0001) and had reduced glucose clearance as determined by an intraperitoneal glucose tolerance test (one-way ANOVA, p<0.0001). Mice were exposed to isopropyl tiglate (IT) or clean air using a cyclic odor stimulation paradigm to activate the M72 odorant receptor. Immunocytochemical procedures demonstrated that the number of periglomerular (PG) cells did not decrease with fatty diets surrounding either the medial or lateral M72 glomerulus (one-way ANOVA; lateral (lat) – F(2, 11) = 0.4155, p = 0.67; medial (med) – F(2, 13) = 0.7149, p=0.5295). The M72 glomerular volume was also unaffected following DIO, which is consistent with PG cell abundance (one-way ANOVA; lat – F(2, 11) = 0.09720, p = 0.9081; med – F(2, 13) = 0.3194, p = 0.7321). Interestingly, unlike OSNs, PG cells do not show a reduction in abundance following DIO, which may suggest that PG cells possess resistance to the apoptotic effects of DIO via uninterrupted PG cell neurogenesis or other neuroprotective factors. The increase in c-fos immediate early gene activation with odor stimulation for PG cells surrounding the lateral and medial M72 glomerulus was not significantly different across dietary treatment (lat – Kruskal-Wallis = 2.367; p=0.3063; med – Kruskal-Wallis = 1.565; p = 0.4572). However, the mean fold change in c-fos positive PG cells revealed that the medial M72 glomerulus had decreased odor activation following DIO (CF = 5.45x, MHF = 2.49x, HF = 1.65x), while the lateral glomerulus had less decrease due to diet (CF = 2.95x, MHF = 1.95x, HF = 2.18x). This suggests that surviving OSNs projecting to the medial M72 glomerulus trend to have reduced activation by their ligand, IT, following DIO, but those projecting to the lateral glomerulus have similar odor sensitivity as CF mice.

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.

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 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 moreThe Gulf of Mexico is known for the biogeochemical impacts of significant riverine nutrient inputs on the ecosystem. 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 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.

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 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.

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 moreIn hadronic physics, photoproduction experiments, in complement with nucleon deep inelastic scattering experiments, seek to better understand the spectrum of excited baryons, as well as the structure and QCD interactions of the quarks and gluons inside them. In recent years, the amount of data for light-meson photoproduction has grown and expanded into higher energies. Because photons have the same spin-parity as vector mesons (JP = 1-), vector mesons have a significant contribution to the photoproduction cross section at energies above 1.7 GeV via t-channel production. The study of vector meson production is of interest for the study of both resonant production and t-channel production. Out of the vector meson decays, the reaction pp𝜑 has been studied the least. The |ss〉content of the 𝜑 makes this decay mode interesting considering the suppressed strange content of the proton. Here we analyze the aforementioned decay by using data taken at Jefferson Lab using the CLAS spectrometer with energy up to 4.1 GeV. Using the data for p,K+,K- final states (since 𝜑K+K- with a ~ 49% branching fraction), a cross section for this decay mode has been calculated in the energy range 1.7 - 4.1 GeV.

Show moreThis study investigates the socioeconomic impact that a decline in oyster population in Apalachicola Bay (the Bay) has had on Franklin County oyster workers. Interviews of local oyster workers and other stakeholders were conducted to determine the extent of the socioeconomic impact of the oyster decline, and to consider a connection between the level of local education on Bay related technical issues and oyster conservation. The decline in oyster population has caused many oyster workers to find employment in other industries which has resulted in an alteration of the local culture. The limited education and understanding of technical issues concerning the oyster collapse has caused frustration and discontent among oyster workers, which is counterproductive to the common goal of restoring Apalachicola Bay to its once high productivity.

Abstract Social media has revolutionized the way people communicate with one another, allowing individuals to communicate with anyone in the world at any time. These additional social opportunities increase the frequency with which people can seek attention and enhance their image. Related maladaptive social behaviors have been tied to undermined psychological wellbeing.

Show moreAbstract Social media has revolutionized the way people communicate with one another, allowing individuals to communicate with anyone in the world at any time. These additional social opportunities increase the frequency with which people can seek attention and enhance their image. Related maladaptive social behaviors have been tied to undermined psychological wellbeing. Because deficits in self-control have been linked to false presentations and dishonesty in “real life,” we investigated whether self-control may predict such behaviors on social media, specifically Facebook. Study 1 furnished evidence for the reliability and validity of our attention-seeking and image-enhancement scales, and demonstrated that trait self-control is negatively related to attention-seeking and image-enhancement. Study 2 replicated these findings while also employing an experimental design to test the causal link between trait and state self-control (i.e., ego depletion) and actual behavior online. However, depleted participants were not more likely than nondepleted participants to make an attention-seeking or image-enhancing post on Facebook. Implications suggest that self-control may be a good target for interventions that protect against social media’s negative effects on wellbeing.

Show moreThe percentage of seniors in the western world that use computers and mobile devices has increased dramatically in the last decades, however this number is still considerably lower than that of younger adults. To further explain this relationship, this paper has explored the impact of the factors of functional health limitations and fluid intelligence on technology use and age. To do this, this paper used previous data collected by the Center for Research and Education on Aging and Technology Enhancement (CREATE) consisting of a sample of 1,204 adults over the age of 18. The participants completed a battery including self-rated health, technology experience, and measures of cognitive abilities, along with other measures that were not discussed in this paper. This study was conducted using data from the CREATE I data set and analyzed variables of age, fluid intelligence, functional health limitations, and technology use. The findings in this study show a significant positive interaction between age and functional health limitations on technology use, suggesting that technology use is impacted more among younger adults with functional health limitations than older adults with functional health limitations.

Show moreWestern ecology relies heavily on dichotomous conceptions of individuals’ relations to their society and to their environment, placing nature and society in opposition to one another as distinct realms. This dichotomy motivates the exploitative, consumerist relationship between Western societies and the natural resources exchanged as matters of economy and production. The Waiãpi indigenous community lives within a different social world composed of starkly different frameworks of society that exist apart from dichotomous understandings. This work deconstructs the nature-society dichotomy, turning to Waiãpi myths and stories as evidence of Waiãpi conceptions of being. These stories reveal a fluid cosmos, constructed of fractal layers of subjectivity in which agents are subjected to a greater whole. Furthermore, they reveal a relational net of “dividual” beings understood only insofar as they relate to others. These attributes of the Waiãpi social world stand in critique of Western modernity and vitiate the nature-society dichotomy.

Show moreArab Tribes are a powerful social, cultural, and political institution throughout the Arab world. Though they originated from a common ancestry, thousands of years of conquest and migration resulted in a broad range of tribal characteristics and practices. Even between closely related tribes in the Levant, there are differences from country to country. Traditionally, Arab tribes are defined through an international relation’s paradigm. This is exemplified with the United States’ rapid assessment of the tribal system in Iraq during the Iraq War in order bolster support for the U.S. led coalition. However, this framework fails to understand the historical and cultural foundations of the system and often results in negative consequences including the growth and expansion of multinational non-state actors, sectarianism, and terrorism. This research seeks to develop a framework that integrates an understanding of the historic relevance of tribes with the function and role of tribes in the modern context with an emphasis on the impact of tribal identity on tribal relations with the state from the late Ottoman era into the present and on forced migration in the present Syrian crisis.

The Notch signaling pathway is an evolutionarily conserved method of cellular communication which coordinates cell differentiation and cell fate determination events throughout many different tissues in all metazoans.

Show moreThe Notch signaling pathway is an evolutionarily conserved method of cellular communication which coordinates cell differentiation and cell fate determination events throughout many different tissues in all metazoans. While Notch is classically referred to as a tumor suppressor gene, cases of oncogenic behavior have also been documented; this creates uncertainty regarding the pathway’s role in a tumor under tissue specific conditions. My project utilized follicle cells within the ovaries of Drosophila melanogaster as a model system to examine upregulation of Notch signaling in an epithelial cell tumor environment (generated by knockdown of lgl: a well-established tumor suppressor). While overexpression of Notch is not sufficient for tumor formation, I found that there is a significant increase in tumor area when overexpressed in Lgl knockdown multilayered follicle cells. These tumor tissues were then allografted into adult wildtype females and found to survive and grow over the course of 9 days. These results suggest a novel tumorigenic role of overactive Notch signaling when the tumor suppressive function of lgl is lost, and raise questions regarding which specific interactions were responsible for the observed incidence of follicle cell proliferation in this system.

Show moreAs part of a larger study of students reasoning in linear algebra, this research analyzes how students make sense of language and notation introduced by instructors when learning matrices as linear transformations. This paper examines the implementation of a portion of an inquiry-oriented instructional sequence in which students generate, compose, and invert matrices that ‘italicize’ a given letter “N” placed on a 2-dimensional Cartesian coordinate system. This inquiry-oriented approach is a specific type of student-centered instruction where students learn new mathematical concepts by working on thought-provoking tasks that prompt exploration of important concepts, engaging in mathematical discussions, developing and testing conjectures, and explaining and justifying their thinking. I analyzed video data of two different instructors implementing the italicizing N materials in a time span of three class days each lasting between 50 to 75 minutes. I conducted my analysis by noting how instructors introduced and formalized mathematical language and notation in the context of this particular instructional sequence, and then related that to the ways in which that language and notation was subsequently taken up by students. This work was conducted as a comparative case study in order to allow me to build theory about the relationship between student learning and the ways in which language and notation are introduced. I also discuss implications for when and how instructors might introduce definitions in order to help students bridge the gap between their informal and intuitive ways of thinking and more formal mathematical language and notation.

Show moreThe development of printing in the fifteenth century did not transform the medieval Book from the manuscript to the modern mass-market paperback overnight—instead, changes in the design of late medieval texts occurred gradually over the first decades of printing in Europe. This has significant repercussions for the way we should evaluate terms like "print culture" and how we understand features of book production traditionally assigned to manuscript or print. To illuminate this transition, I will discuss the changes in the structuring and layout of books at the end of the fifteenth century, with a particular focus on "rubrication," the strategic use of red ink to guide readers' eyes through the pages of the medieval manuscript. Despite the development of printing and its affordances for using font, size, and spatial arrangement of the text to orient the reader, rubrication continued to be used in complex and multivalent ways throughout early printing. A detailed case study of several early print and manuscript editions of the Gesta Romanorum—one of the most popular storybooks of the Late Middle Ages—reveals a gradual transition from the use of rubrication and other visual cues in the medieval manuscript to the spatially-typographically oriented printed book. This transition was characterized by continuity and measured evolution—rather than an abrupt shift to something as concrete as "print culture"—in which the new technology emulated its predecessor as it progressively developed its own identity and made its own imprint on literate society.

Show moreThis thesis considers the collision of two entities in the modern Caribbean: systems of authoritarian rule and the artistic reactions to these systematically destructive processes. A concise examination of the Cuban novel Antes que Anochezca (1992) by Reinaldo Arenas and the Haitian film L'Homme sur les Quais (1993) by Raoul Peck explores how the creators of the works reveal the transformational processes employed by dictatorships that eventually degrade nature, government, bureaucracy, interpersonal relationships, and eventually man himself. This in analyzed within the framework of Marx's notion of alienation, which is seen as a philosophical cousin to Freire's notion of oppression. This all culminates with a metaphysical appreciation of the function of art as a means of reclaiming the voice of the individual and the nation as a whole in both the midst and the aftermath of ruthless, dehumanizing tyranny.
