External Hyperlinking Practices In Print-Based And Online-Native News Sites, Sarah K. Wisniewski Jan 2015

External Hyperlinking Practices In Print-Based And Online-Native News Sites, Sarah K. Wisniewski

Graduate Theses, Dissertations, and Problem Reports (ETD)

This paper describes the differences in the use of external hyperlinks between print-based and online-native news sites. External hyperlinks are links that direct the user to a page outside the original domain, such as the Huffington Post including a link to Wikipedia. A subcategorization of online-native sites into three distinct waves based on launch dates and corresponding to recent transitions in communications technology is proposed. A quantitative content analysis of hyperlinks embedded in the text of articles from print-based, second-wave, and third-wave news sites in 2005, 2010, and 2014 suggests that print-based and online-native news sites do use external hyperlinks …

Evaluating Thermal Behavior And Use Of Maturity Method In Mass Concrete, Tahsin Alper Yikici

Graduate Theses, Dissertations, and Problem Reports (ETD)

Large concrete placements with increased amount of cement contents result in higher peak temperatures as well as higher temperature differentials between the concrete surface and the interior. Such high thermal differentials can result in large temperature-induced stresses and increases the risk of early age cracking. To minimize this risk, temperature development within the structure must be known. Throughout the project, fourteen different sub-structures from six different bridge projects and four 6-ft cube blocks, in total of eighteen structural elements in nine different districts were instrumented successfully with sacrificial loggers, and temperature-time histories of these elements were monitored. Laboratory studies involved …

Spanning Trails And Spanning Trees, Meng Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are two major parts in my dissertation. One is based on spanning trail, the other one is comparing spanning tree packing and covering.;The results of the spanning trail in my dissertation are motivated by Thomassen's Conjecture that every 4-connected line graph is hamiltonian. Harary and Nash-Williams showed that the line graph L( G) is hamiltonian if and only if the graph G has a dominating eulerian subgraph. Also, motivated by the Chinese Postman Problem, Boesch et al. introduced supereulerian graphs which contain spanning closed trails. In the spanning trail part of my dissertation, I proved some results based on …

Decellularized Matrix And Cartilage Regeneration: A Focus On Developing A Matrix With Anti-Inflammation And Micromechanical Properties, Ying Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Osteoarthritis (OA) is predicted to be the fourth leading cause of disability worldwide by the year 2020. Stem cell-based therapy is a promising biological approach for the treatment of cartilage defects. However, adult stem cells tend to become replicatively senescent when they are expanded on conventional plastic flasks. Decellularized extracellular matrix (dECM) provides an expansion system to rejuvenate and maintain the chondrogenic phenotype of stem cells for cartilage repair. In addition, joints with cartilage defects normally have inflammation to some extent; several stimuli, such as Reactive Oxygen Species (ROS) and Interleukin-1 (IL-1), reportedly induce apoptosis of chondrocytes. The tolerance of …

Social Structure And Clearance Rates: The Effect Of Neighborhood Characteristics On Aggravated Assault Case Outcome, Brad Silberzahn

Graduate Theses, Dissertations, and Problem Reports (ETD)

The ability of police to make an arrest for a crime is one of the most visible aspects of the criminal justice system. As a result, it is no surprise that clearance rates are one of the most commonly used measures of police effectiveness. Previous studies of clearance rates focus heavily on the clearance of homicide cases, as many researchers examine the effect of individual level characteristics on case outcomes. Using Donald Black's theory of law, which places an emphasis on social space, i.e., vertical and horizontal distances between victims and offenders, this study examines the effect of neighborhood characteristics …

The Role Of Self-Efficacy And Social Support In Emerging Adults' Physical Activity, Nicole M. Silva Jan 2015

The Role Of Self-Efficacy And Social Support In Emerging Adults' Physical Activity, Nicole M. Silva

Graduate Theses, Dissertations, and Problem Reports (ETD)

Emerging adulthood is a time where emerging adults develop health behaviors that persist throughout the life span (Barnett et al., 2014). However, only 55.4% of emerging adults engage in the recommended amount of physical activity each week (U.S. Department for Health and Human Services, 2013). The current study examined two factors that are associated with physical activity, specifically self-efficacy and social support, in 403 (M age = 19.25, SD = 1.12) emerging adults. Linear regressions indicated that emerging adults who reported higher levels of general self-efficacy (beta = .13, p < .05), domain self-efficacy (beta = .33, p < .05), and support from the entire social network (beta = .50, p < .001) engaged in more physical activity. Support from the entire social network still accounted for a significant portion of the variance in physical activity when accounting for general or domain self-efficacy (beta for support = .48, p < .001 and .30, p < .05, respectively). The differential effects of source of support (i.e., family and friends) and type of support (i.e., esteem support, informational support, and companionship support) were also examined. Emerging adults who reported higher levels of support from family (beta = .22, p < .001) and friends (beta = .33, p < .001) engaged in more physical activity. Although emerging adults reported receiving more esteem support from family (M = 2.95, SD = 1.23) compared to friends (M = 2.74, SD = 1.15), esteem support from friends (beta = .33, p < .001) had a larger effect on physical activity than esteem support from family (beta = .21, p < .05).

Comparison Of The Fatigue Characteristics Of Recycled Asphalt Pavements, Lara Smith Jan 2015

Comparison Of The Fatigue Characteristics Of Recycled Asphalt Pavements, Lara Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

When the service life of asphalt pavement has expired, it can be reclaimed and reused as a percentage of new pavement. This recycled asphalt pavement (RAP) usually is exposed to years of environmental conditioning and oxidation, which stiffens the asphalt binder. As the binder stiffens, certain engineering properties change, such as dynamic modulus, and the pavement begins to experience distresses.;The asphalt mixture performance tester (AMPT) is a new performance testing machine that applies load cycles within a cell that also acts as an environmental conditioning chamber. This research focused on the using the AMPT to determine dynamic modulus and fatigue …

School Climate, Early Adolescent Development, And Identity: Associations With Adjustment Outcomes, Megan Lorraine Smith Jan 2015

School Climate, Early Adolescent Development, And Identity: Associations With Adjustment Outcomes, Megan Lorraine Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early adolescence is a time of risk and exploration for young people. In a period of development marked by increasing independence, young people are still learning the skills necessary for success in their adult lives. Positive development is impacted not only by individual characteristics, but also by the environments and social supports present. Adolescents spend a significant amount of time in schools, thus schools are an important context to study in regards to positive adolescent outcomes. Self Determination Theory (SDT, Deci & Ryan, 2000) posits that the degree to which an individual's basic psychological needs for autonomy, competence, and relatedness …

Uneven Development And Peri-Urbanization In South Africa: Exploring Landscape Change In Polokwane, South Africa, Jennifer L. Smith Jan 2015

Uneven Development And Peri-Urbanization In South Africa: Exploring Landscape Change In Polokwane, South Africa, Jennifer L. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Changes in local landscapes of South Africa are tied to changing social and economic structures of the post-apartheid era. Though there have been significant shifts in land and labor laws, as well as economic policies, between the apartheid era and current times, significant inequalities between communities remain a defining characteristic of the post-apartheid landscape. This research contends that through a combination of social processes occurring between the local, national, and global scales, local landscape is produced unevenly as a manifestation of the coproduction of space. Using a structuralist approach, the research examines local change through the theoretical lenses of uneven …

Word Play: Modernist Women And Performative Writing, Kathryn Ridinger Smorul

Graduate Theses, Dissertations, and Problem Reports (ETD)

In Word Play: Modernist Women and Performative Writing I read modernist literary texts informed by theories about theatre, performance, and art. Exploring lesser-known works of Djuna Barnes, Gwendolyn Bennett, Edna St. Vincent Millay, and Mina Loy, I combine literary analysis and performance studies to discover how modernist texts "talk back" to performance theories.;Performance studies, of course, is an inter-discipline that includes anthropology, sociology, performing arts, and literary theory. Modernist authors, influenced as they often are by art, performance, and ritual, incorporate these interdisciplinary interests into a writing practice, specifically performative writing. Performative writing is not so much a matter of …

Cultivating Intelligent Consumption: The United States Food Administration And Food Control During World War I, James H. Smith Jan 2015

Cultivating Intelligent Consumption: The United States Food Administration And Food Control During World War I, James H. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines government food control in the United States during the First World War. More specifically, it looks at the food conservation program, and the associated propaganda, formulated by the United States Food Administration (USFA). The USFA was a wartime government agency headed by future president Herbert Hoover. I argue that the philosophy guiding the Food Administration's food control program was clearly influenced by a particular strain of progressivism that men like Hoover subscribed to. Using the input of experts in various fields such as nutrition, physiology, and advertising, the government was able to present a message to the …

Christ In The Margins: Confronting Racism Through The (Written) Word In Post-Civil War America, Cara L. Snider Jan 2015

Christ In The Margins: Confronting Racism Through The (Written) Word In Post-Civil War America, Cara L. Snider

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation examines fictional texts of the late nineteenth century in order to recover the response of progressive Christian writers facing a growing tide of racial violence, injustice, and segregation in the postbellum decades. By investigating the works of Mark Twain, Charles Sheldon, Frances Harper, and Sutton Griggs, I argue that we gain access to a cadre of writers who sought to translate emerging strains of New Theology into practical means of race reform. They regarded their novels as sermons to the masses and saw writing as a sacred practice of communicating the Word to fellow believers; and their brand …

Impacts Of Multiple Stressors On Dryland Vulnerability And Land Conflict Among Border Communities, Alvin Maingi Solomon Jan 2015

Impacts Of Multiple Stressors On Dryland Vulnerability And Land Conflict Among Border Communities, Alvin Maingi Solomon

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines how individuals and groups respond to prevailing politico-economic and biophysical changes and how the adjustments they make influence and are influenced by their social relations and material condition in spatial and temporal terms. This dissertation comprises of three parts: The first part is a critique of the climate-conflict relationship debate and the problems associated with studies pushing for a causal relationship between climate variables and conflict. I argue that scholars lack of attention on varying institutional capacities and the focus solely on environmental factors as trigger mechanisms for conflict leads to misleading arguments about conflict distribution and …

Clustering By Academic Major At Historically Black Colleges And Universities (Hbcus), Aaron Goodson Jan 2015

Clustering By Academic Major At Historically Black Colleges And Universities (Hbcus), Aaron Goodson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Follow-up studies of clustering by academic major, the dynamic of 25% or more of the student-athletes on a roster pursuing the same academic major, indicate that it still occurs in revenue-generating sports (Fountain & Finley 2009, 2011; Otto, 2012). Clustering challenges the notion that student-athletes have control over their collegiate academic experience and reveals that their educational pursuits may not align with their professional goals or provide a meaningful educational experience (Sharp & Sheilley, 2008). Research on clustering is absent in member institutions of different NCAA divisions, institutions with unique missions and history (such as Historically Black Colleges and Universities …

Family Distress, First-Generation College Status, And Financial Stress As Predictors Of Alcohol Use In College Students Seeking Mental Health Treatment, Narayan Jeremy Gold

Graduate Theses, Dissertations, and Problem Reports (ETD)

Increasing numbers of students have been presenting for mental health treatment on college campuses to address their alcohol use (Gallagher, 2010). The goal of the current study was to examine the relationship between presenting alcohol use, family distress, college generational status (first-generation to college or non-first-generation to college), and financial distress. By examining the predictive nature of these variables screening could be improved to help identify and help students who are more at risk of experiencing the negative impact of alcohol use. It was hypothesized that higher levels of family distress, more financial stress, and being a first-generation college student …

Self-Assessed Health In The Context Of Daily Life, Allyson S. Graf Jan 2015

Self-Assessed Health In The Context Of Daily Life, Allyson S. Graf

Graduate Theses, Dissertations, and Problem Reports (ETD)

Little research has examined short-term change in self-assessed health (SAH), limiting what is known about the influence of daily life on these personal health evaluations. Investigating short-term change in SAH can add to our understanding of the ways in which SAH relates to future health outcomes. Therefore, the current study sought to examine change and stability in SAH across the day and across the week in an age-diverse community sample (n = 57, ranging in age from 25 - 71 years, 52.6% female). Age, gender, and neuroticism were hypothesized to systematically influence short-term fluctuation in SAH. Daily hassles and uplifts …

Validation Of An Experimentally Motivated Predictive Model For The Spontaneous Clustering Of Receptors On The Cell Membrane, Emine Guven

Graduate Theses, Dissertations, and Problem Reports (ETD)

Membrane receptors are specialized membrane-bound proteins that facilitate communication be- tween the intracellular and extracellular membrane. They control signal initiation in many im- portant cellular signaling pathways. Cell signaling (or signal transduction) provides the logical inputs individual cells need in order to perform their role in the context of the organism. Signal- ing molecules such as hormones, neurotransmitters or growth factors, are secreted by cells in the organism as a result of certain conditions; the cells receiving the signal change (or maintain) their state in response to the signaling input. The incoming information is processed and the response is formulated …

Lng Station Analysis For The Prediction Of Pressure Rise And Vented Emissions, John T. Hailer Jan 2015

Lng Station Analysis For The Prediction Of Pressure Rise And Vented Emissions, John T. Hailer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Liquefied natural gas is seeing increased usage in the over-the-road trucking sector. Stations which refuel LNG vehicles sometimes emit natural gas into the atmosphere through a pressure relief valve due to over pressurization of the storage tank. Methane, the dominant constitute in natural gas, is considered a more potent greenhouse gas than carbon dioxide. However, natural gas has less of a carbon foot print than other fuels such as gasoline, diesel, and coal when burned giving it a global warming potential (GWP) advantage. Emission of methane into the atmosphere degrades the GWP advantage of burned methane or natural gas. Therein …

Discovery Of A Novel Oocyte-Specific Krab-Containing Zinc Finger Protein Required For Early Embryogenesis In Cattle, Jacqelyn M. Hand Jan 2015

Discovery Of A Novel Oocyte-Specific Krab-Containing Zinc Finger Protein Required For Early Embryogenesis In Cattle, Jacqelyn M. Hand

Graduate Theses, Dissertations, and Problem Reports (ETD)

Much of the loss of potential offspring in cattle is concentrated in the early embryonic period. Maternal mRNAs that accumulate in the oocyte during oogenesis have important functional roles during the initial stages of embryonic development, before embryonic genome activation. It is well regarded that the oocyte plays an active role in regulation of key aspects of the reproductive process required for fertility. What is more, oocyte-specific transcription factors seem to be the controlling feature influencing germ cell success throughout oogenesis, fertilization, and early embryonic development. Of the remarkably diverse array of transcription factors encoded by mammalian genomes, about two-thirds …
