Evaluation Of Crash Modification Factors And Functions Including Time Trends At Intersections, Jung-Han Wang Jan 2016

Evaluation Of Crash Modification Factors And Functions Including Time Trends At Intersections, Jung-Han Wang

Electronic Theses and Dissertations

Traffic demand has increased as population increased. The US population reached 313,914,040 in 2012 (US Census Bureau, 2015). Increased travel demand may have potential impact on roadway safety and the operational characteristics of roadways. Total crashes and injury crashes at intersections accounted for 40% and 44% of traffic crashes, respectively, on US roadways in 2007 according to the Intersection Safety Issue Brief (FHWA, 2009). Traffic researchers and engineers have developed a quantitative measure of the safety effectiveness of treatments in the form of crash modification factors (CMF). Based on CMFs from multiple studies, the Highway Safety Manual (HSM) Part D …

The Frequency Of The Passive Voice In Freshman Academic Books, Basma Moreb Jan 2016

The Frequency Of The Passive Voice In Freshman Academic Books, Basma Moreb

Electronic Theses and Dissertations

The use of passive voice has long been an area of difficulty for English learners. Celce-Murcia & Larsen-Freeman (2015) noted that it is learning when to use the English passive that presents the greatest long-term challenge to ESL/EFL students (p. 352). Because textbooks are a source of language input for English learners, this study investigated the frequency of passive voice verbs in samples from four academic textbooks in courses commonly taken by freshmen. The study also examined whether there are significant differences between the frequencies by textbook. The data was collected from four General Education Plan (GEP) subject textbooks used …

Rethinking Drinking: A Paradigm Shift For Estimating Social And Behavioral Harm, Thomas Hall Jan 2016

Rethinking Drinking: A Paradigm Shift For Estimating Social And Behavioral Harm, Thomas Hall

Electronic Theses and Dissertations

This study challenges old saws about negative consequences attributed to alcohol use. Previous research findings associate negative social and behavioral consequences with alcohol consumption, as if college students only do regrettable things when they are drunk. Typical research related to negative consequences and alcohol use relies on retrospective self-reporting. Investigators often frame negative consequences as outcomes of problematic drinking or, as more commonly labeled, "binge drinking." In the nomenclature of prevention, binge drinking is not a direct measure of alcohol use resulting in intoxication; it is a hypothetical tipping point, predicting an increased likelihood of the incidence of negative consequences …

Preparing For The Inevitable: Sensemaking In Parent-Child Discussions Of Death, Carrie Ann Wartmann Jan 2016

Preparing For The Inevitable: Sensemaking In Parent-Child Discussions Of Death, Carrie Ann Wartmann

Electronic Theses and Dissertations

Death is something everyone will eventually encounter, yet American society has a tendency to avoid or deny death in everyday life and language. Death makes people uncomfortable, and many view it as a topic too complex for children to understand. Children, however, witness big and little deaths in their lives: of pets, relatives, plants, and favorite fairy tale characters. When a child experiences a death, he or she may have questions for parents or other trusted adults which our current avoidance-geared society does not prepare adults for. Children exist in a specific cultural context, and learn rules and expectations of …

An Examination Of The Lived Curiosity Experiences Of Traditionally-Aged Freshmen Pursuing And Education Degree, Susan Kelly Jan 2016

An Examination Of The Lived Curiosity Experiences Of Traditionally-Aged Freshmen Pursuing And Education Degree, Susan Kelly

Electronic Theses and Dissertations

The benefits of being curious continue beyond infancy and early childhood. Curiosity has been linked to academic achievement, memory, and lifelong learning. Yet curiosity type behaviors in academic settings are infrequently observed. This is a concern because some of the students graduating from the educational system will be the teachers responsible for fostering conditions that spark curiosity and exploration for future students. These prospective teachers' lived curiosity experiences will influence their future teaching beliefs and practices. Yet few studies have been conducted that illuminate the lived curiosity experiences of prospective teachers. The research question that guided this study was, what …

The Lived Experiences Of Elementary Students With Disabilities Self-Advocating Through Speaking And Writing, Lindsey Massengale Jan 2016

The Lived Experiences Of Elementary Students With Disabilities Self-Advocating Through Speaking And Writing, Lindsey Massengale

Electronic Theses and Dissertations

Writing and self-advocacy skills are important for all students, including individuals with disabilities. Within the K-12 setting, those skills are taught, but emphasis changes as students progress through the grade levels. At the elementary level, writing is more prominent; whereas, in high school, self-advocacy becomes a focus. In this study, the researcher used a phenomenological research design to explore the lived experiences and preferences of elementary students with disabilities and their use of self-advocacy strategies in the inclusive setting, both in writing and speaking. The phenomenon was explored over an eleven-week period in a second grade, inclusive classroom. The conceptual …

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz Jan 2016

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz

Electronic Theses and Dissertations

Prevention efforts targeted at children and adolescents are important because alcohol consumption contributes to the three leading causes of death in this among 12-20 year-olds: unintentional injury, homicide, and suicide. Research on the causes of alcohol misuse traditionally focused on pharmacological and genetic explanations, but models have expanded to include cognitive processes in the development of alcohol use patterns. Alcohol expectancies, or beliefs about the effects of alcohol, are an important influence on drinking behavior. Expectancies exist prior to the initial drinking experience, predict the onset of alcohol consumption, differentiate both children and adults in terms of light- and heavy-drinking …

Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short Jan 2016

Superwholock: An Analysis Of Subculture In A Microblogging Setting, Dean Short

Electronic Theses and Dissertations

While subcultural research has always been a common focus of sociological research, most such studies focus on deviant subcultures. This has led to a glut of information on countercultures and criminal subcultures, but relatively little study of less visible subcultures. While there is a great deal of research on the sociology of sport, including sport fandom, there is very little on other fandom subcultures. While this makes sense, as they are niche subcultures, the popularity of formerly niche entertainment is expanding rapidly. Much of this fandom renaissance owes its existence to the Internet, and its ability to bring geographically separate …

Don't Let The World Rot: Anarchism, Hardcore Music, And Counterculture, Pearson Bolt Jan 2016

Don't Let The World Rot: Anarchism, Hardcore Music, And Counterculture, Pearson Bolt

Electronic Theses and Dissertations

Hardcore music is intrinsically anarchistic. The hardcore music scene represents a radical departure from contemporary society. Rejecting the materialism, militarism, and hedonism of the mainstream music scene—and, by extension, modern culture—hardcore music presents an alternative lifestyle rooted in solidarity, equality, and liberty. Indeed, the culture of the hardcore scene approaches a transitive, nomadic model of an anarchistic commune built on resistance as a way of life. In this study, I identified the ways music and lyrics craft attitudes and environments for revolt and rebellion, cultivating critical thinking and disobedience in equal measures. In order to understand the hardcore community, I …

Pasture Management, The Red Imported Fire Ant (Solenopsis Invicta) And Dung Beetle Mediated Ecosystem Services, Christen Steele Jan 2016

Pasture Management, The Red Imported Fire Ant (Solenopsis Invicta) And Dung Beetle Mediated Ecosystem Services, Christen Steele

Electronic Theses and Dissertations

Grazing animals in Florida deposit over 20 million metric tons of dung per year, making dung a significant non-point source of pollution (extrapolated from Fincher, 1981). Degradation of this dung occurs naturally, primarily due to a diverse group of beetles (Order Coleoptera) primarily in the families Scarabaeidae and Geotrupidae(hereafter dung beetles). Dung that is not degraded becomes a non-point source of pollutants and may be leached into water bodies. Additionally, dung provides an incubation site for the pests and parasites of both humans and livestock. Thus, as dung beetles consume and degrade dung, they provide a multitude of ecosystem services …

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa Jan 2016

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa

Electronic Theses and Dissertations

Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …

Bmp-7 Inhibits P38 And Jnk Pathways And Increases M2 Macrophage Differentiation To Reduce Atherosclerosis In Apolipoprotein E-/- Mice, Heidi Shoulders

Electronic Theses and Dissertations

We have previously shown that treating atherosclerosis with bone morphogenetic protein-7 (BMP-7) affects the presence of macrophage subtypes in vitro, however it remains unknown whether BMP-7 treatment affects development and progression of atherosclerosis in vivo at an early and mid-stage of the disease. We therefore performed a Day 5 (D5) and Day 28 (D28) study to examine BMP-7's potential to affect monocyte differentiation. Atherosclerotic plaque formation was developed using our standard method and ApoE-/- mice were sacrificed at D5 and D28 post-surgery. Treatment animals received intravenous injections of BMP-7 at 200µg/kg of bodyweight. Hematoxylin and Eosin morphological stain shows that …

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun Jan 2016

Improved Interpolation In Sph In Cases Of Less Smooth Flow, Oddny Brun

Electronic Theses and Dissertations

We introduced a method presented in Information Field Theory (IFT) [Abramovich et al., 2007] to improve interpolation in Smoothed Particle Hydrodynamics (SPH) in cases of less smooth flow. The method makes use of wavelet theory combined with B-splines for interpolation. The idea is to identify any jumps a function may have and then reconstruct the smoother segments between the jumps. The results of our work demonstrated superior capability when compared to a particular challenging SPH application, to better conserve jumps and more accurately interpolate the smoother segments of the function. The results of our work also demonstrated increased computational efficiency …

The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring Jan 2016

The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring

Electronic Theses and Dissertations

Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …

Neurological Profile Of Older Apoe-Pon1 Double Knockout Mice, Connie Mitra

Electronic Theses and Dissertations

Atherosclerosis is a cardiovascular disease where plaques made up of lipids in the form of cholesterol ester build up in the carotid and innominate arteries that supply blood to the brain. Accumulation of the plaques limit the flow of blood and nutrients to the brain, leading to diminished oxygen supply, increased oxidative stress and cell death. All these have been implicated in Alzheimer's disease (AD). Alzheimer's disease, a chronic, progressive, age related neurodegenerative disorder is the most common form of dementia in the elderly accounting for 60-80% of the cases. Clinically, Alzheimer's disease is characterized by loss of memory, damage …

Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar Jan 2016

Multidimensional Room-Temperature Fluorescence Microscopy For The Nondestructive Analysis Of Forensic Trace Textile Fibers, Nirvani Mujumdar

Electronic Theses and Dissertations

The purpose of this dissertation is to advance nondestructive methodology for forensic fiber examination. Non-destructive techniques that can either discriminate between similar fibers or match a known to a questioned fiber – and still preserve the physical integrity of the fibers for further court examination - are highly valuable in forensic science. A challenging aspect of forensic fiber examinations involves the comparison of fibers colored with visually indistinguishable dyestuffs. This is not an uncommon situation, as there are numerous indistinguishable fibers pre-dyed with commercial dyes of virtually identical colors. Minimal chemical structural variations are actually encouraged by the dye patent …
