Utilizing Early Cellular Changes To Explore Biological Responses To Individual Chemical And Mixture Exposures, Julie Anne Vrana Jan 2015

Utilizing Early Cellular Changes To Explore Biological Responses To Individual Chemical And Mixture Exposures, Julie Anne Vrana

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humans are continuously exposed to a vast number of chemicals, whether it be from the air we breathe, the water we drink, or the medications we take daily. Early cellular changes after exposure to chemical insult, both individual chemicals and mixtures (two or more chemicals) thereof, can offer a wealth of information about cellular adaptation (e.g., cell death or survival decision processes). From this understanding, better prediction models for chemical risk assessment, such as toxicity or carcinogenicity, can be elucidated. Further, these prediction models can greatly improve the large backlog of chemicals waiting to be evaluated for potential adverse effects. …

Evaluating Work-Related Risk Factors Associated With Low Back Disorders In The Roofing Industry, Di Wang Jan 2015

Evaluating Work-Related Risk Factors Associated With Low Back Disorders In The Roofing Industry, Di Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Roofers have long suffered from low back disorders (LBDs), which is a primary non-fatal injury in construction. The harsh work environment exposes the roofers to a diversity of physical exposures which may cause severe LBD injuries. Until now, most of research on roofing safety has been mainly focused on fatal injury risks, such as falls from height, leaving much to be desired in the risk assessment of non-fatal, cumulative musculoskeletal disorders among this population. Existing ergonomics studies have identified several physical risk factors associated with LBDs in workplaces and developed predictive models for general LBD risk assessments. However, these models …

Attenuation Of Spatial Memory Impairment In A Tau Mouse Model Of Alzheimer's Disease With Riluzole, Daniel S. Weitzner Jan 2015

Attenuation Of Spatial Memory Impairment In A Tau Mouse Model Of Alzheimer's Disease With Riluzole, Daniel S. Weitzner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Individuals at risk for developing Alzheimer's disease (AD) often demonstrate hyperactivity in areas of the memory network, such as the hippocampus, prior to AD diagnosis. Evidence suggests that this hyperactivity might be a contributing factor to the development of AD. Tau, a protein responsible for binding and maintaining microtubules, has been implicated as a factor in hyperactivity, potentially through its alterations in glutamate signaling. Glutamate, the primary excitatory neurotransmitter in the central nervous system, is essential for learning and memory. However, excess glutamate that accumulates in the synapse can lead to neuron loss and eventual behavioral impairments. Recently, our lab …

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 …

Decellularized Matrix And Cartilage Regeneration: A Focus On Developing A Matrix With Anti-Inflammation And Micromechanical Properties, Ying Zhang Jan 2015

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 …

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).

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 …

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 …

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 …

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 …

A Study Of Self Consolidating Concrete For Cast In Place Applications: Current Practices, Rapid Wcm Determination, And Stability Effects Of Pumping, Jared Hershberger

Graduate Theses, Dissertations, and Problem Reports (ETD)

Self-Consolidating Concrete (SCC) is a relatively new type of concrete mixture that does not require external compaction during placement. Compared to traditional vibrated concrete (TVC), SCC is much more fluid, which gives it the ability to flow and fill formwork without the need for any external compaction efforts. Although the increased cement content and chemical admixtures found in SCC typically results in a higher material cost, the potential for cost savings in reduced construction time and labor are significant. The potential of this relatively new type of concrete have yet to be realized due to a lack of regulation and …
