Approachability Of Nursing Clinical Instructors: Psychometric Assessment Of A Scale Development, Angela Collier Dec 2017

Approachability Of Nursing Clinical Instructors: Psychometric Assessment Of A Scale Development, Angela Collier

Electronic Theses and Dissertations

Approachability of nursing clinical instructors is largely unknown and misunderstood, yet critical for millennial students which currently comprise 82% of nursing students (National League for Nursing, 2014). Nursing education consists of both a didactic and a clinical component. Clinical education is dynamic and allows the student an experiential learning opportunity. Therefore, clinical nursing educators are vitally important. Approachability has been identified in many studies as a leading characteristic of an effective instructor. Although the importance of approachability of the instructor is established, currently no scale exists to measure this concept. The purpose of this study was to examine the validity …

The Pulpit And The People: Mobilizing Evangelical Identity, Tim Moser Dec 2017

The Pulpit And The People: Mobilizing Evangelical Identity, Tim Moser

Electronic Theses and Dissertations

Using ten sermons from five prominent and politically active evangelical megachurch pastors taken from the 2016 presidential campaign season, this case study utilizes frame analysis to understand the political relevance of modern evangelical sermonizing. An inductive frame analysis allows the concept of a collective action frame to be observed as a process and for patterns to emerge from the source text. Within these sermons, ministers offer self-identifying evangelicals a vocabulary with which to understand and describe their own identity. In this context, the Bible is a powerful cultural symbol that represents an allegiance to traditions that are framed as the …

Thinking Before You Act: A Constructive Logic Approach To Crafting Performance-For- Development Narrative, Angela Duggins

Electronic Theses and Dissertations

The intent of this thesis was to test the feasibility of constructing performance-for-development narrative using a constructive logic approach. I created an equation which expressed the sum of non-human-elements as the sum of a narrative with each element serving as a variable. I used a review of persuasion literature to provide insight into the selection and manipulation of each variable. I provided my family as a hypothetical example and used my knowledge of their preferences and communication styles in conjunction with the literature and the equation to craft a narrative which might increase pro-school attitudes in other families like my …


Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield Dec 2017

Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield

Electronic Theses and Dissertations

Sympathetic stimulation occurs in the heart after injuries such as ischemia/reperfusion (I/R) and myocardial infarction and affects myocardial remodeling. Prolonged sympathetic stimulation can result in myocardial dysfunction through its effects on cardiac myocyte apoptosis and myocardial fibrosis. Ubiquitin (UB) is well known for its role of tagging old or damaged proteins for degradation via the UB-proteosome pathway. The role of exogenous UB however, is not fully understood. Previously, our lab showed that β-adrenergic receptor (β-AR) stimulation increased levels of extracellular UB in the conditioned media of adult rat ventricular myocytes and that UB inhibits β-AR-stimulated apoptosis. This study investigates the …

Social-Ecological Factors Affecting Patient Shield Use Among Radiologic And Computed Tomography Technologists, Megan Housenick-Lee Dec 2017

Social-Ecological Factors Affecting Patient Shield Use Among Radiologic And Computed Tomography Technologists, Megan Housenick-Lee

Electronic Theses and Dissertations

Medical radiation is estimated to contribute to over 200,000 deaths annually. Recent increases in the use of radiation-producing medical imaging examinations have led to increasing cumulative radiation dose to the general public. Multiple measures have been taken to address this alarming trend, including physician education, technologist education on dose reduction, and equipment-facilitated dose reduction techniques. Shield use can reduce the primary beam by up to 95%. Medical imaging technologists are the primary individuals responsible for applying shielding during an examination. Currently, literature shows that technologists are not shielding individuals as often as they should.

After pilot testing, medical imaging technologists …


Conceptualization And Measurement Of Spirituality: Towards The Development Of A Nontheistic Spirituality Measure For Use In Health-Related Fields, Valerie M. Hoots Dec 2017

Conceptualization And Measurement Of Spirituality: Towards The Development Of A Nontheistic Spirituality Measure For Use In Health-Related Fields, Valerie M. Hoots

Electronic Theses and Dissertations

Relationships between spirituality and health outcomes are well supported in research; however, measurement of spirituality often reflects a Judeo-Christian framework and is predominantly theocentric, neglecting the increasing religious pluralism and non-traditional expressions of spirituality in the United States. A new measure of spirituality was based on a conceptualization of nontheistic spirituality that is understood to be a relatively stable motivational process entailing a search for sacred connection, with “sacred” being defined by individual perceptions and not necessitating divine association. Item development for the current instrument included an initial pool of 65 items and two phases of revision and content validation. …

Graph Analytics Methods In Feature Engineering, Theophilus Siameh Dec 2017

Graph Analytics Methods In Feature Engineering, Theophilus Siameh

Electronic Theses and Dissertations

High-dimensional data sets can be difficult to visualize and analyze, while data in low-dimensional space tend to be more accessible. In order to aid visualization of the underlying structure of a dataset, the dimension of the dataset is reduced. The simplest approach to accomplish this task of dimensionality reduction is by a random projection of the data. Even though this approach allows some degree of visualization of the underlying structure, it is possible to lose more interesting underlying structure within the data. In order to address this concern, various supervised and unsupervised linear dimensionality reduction algorithms have been designed, such …


Role Of Cannabinoid Receptor Type 2 (Cb2) In Late Stage Atherosclerosis, Makenzie Fulmer Dec 2017

Role Of Cannabinoid Receptor Type 2 (Cb2) In Late Stage Atherosclerosis, Makenzie Fulmer

Electronic Theses and Dissertations

Atherosclerosis is a chronic inflammatory disorder of medium and large vessels. Immune signaling and dyslipidemia are two of several processes which influence lesion development in atherosclerosis. Cannabinoids, such as those found in marijuana, exert their effects through two cannabinoid receptors, CB1 and CB2. Recent studies using CB2 knockout mice and CB2-selective ligands have shed light on a protective role of CB2 in early stages of atherosclerosis. However, the role of CB2 in advanced stages of atherosclerosis remains unclear. To determine if CB2 plays a role in advanced atherosclerotic lesion composition and progression, we investigated the effects of systemic CB2 gene …


Examining The Effects Of Trait Rumination On Hostile Attribution Bias, Kyle A. Suhr Aug 2017

Examining The Effects Of Trait Rumination On Hostile Attribution Bias, Kyle A. Suhr

Electronic Theses and Dissertations

Previous research supports the idea that individuals high in trait anger tend to experience more hostile attribution bias. According to the Integrative Cognitive Model, cognitive factors, such as rumination, may increase the risk of hostile attribution bias and any subsequent aggressive behaviors. Sex differences are apparent in rumination and anger expression. The present research explored the potential role trait rumination plays in hostile attribution bias as well as potential conditional effects of sex on this relationship. Participants were asked to complete a number of self-report measures and vignettes of ambiguously hostile situations adapted to improve reliability. Hypotheses were largely supported …

As part of an ongoing monitoring procedure the participant completed 20m sprint testing through an optical measurement system and isometric-strength testing before and after each phase of training. Sprint velocity, ground contact time and peak force were analysed using Tau-U, smallest worthwhile and percent change statistics. Results indicate sprinting velocity statistically improved while changes in peak force were practically significant and ground contact time remained trivial throughout …


Vertex Weighted Spectral Clustering, Mohammad Masum Aug 2017

Vertex Weighted Spectral Clustering, Mohammad Masum

Electronic Theses and Dissertations

Spectral clustering is often used to partition a data set into a specified number of clusters. Both the unweighted and the vertex-weighted approaches use eigenvectors of the Laplacian matrix of a graph. Our focus is on using vertex-weighted methods to refine clustering of observations. An eigenvector corresponding with the second smallest eigenvalue of the Laplacian matrix of a graph is called a Fiedler vector. Coefficients of a Fiedler vector are used to partition vertices of a given graph into two clusters. A vertex of a graph is classified as unassociated if the Fiedler coefficient of the vertex is close to …


A Novel Method For Synthesis Of Hydroxytyrosol, Emmanuel Onobun Aug 2017

A Novel Method For Synthesis Of Hydroxytyrosol, Emmanuel Onobun

Electronic Theses and Dissertations

Hydroxytyrosol, 3,4-dihydroxyphenolethanol, a naturally occurring polyphenol most common in olive tree (Olea europaea), is one of the most effective member of the polyphenols family, because of its remarkable antioxidant activity, its ability to inhibit oxidation of low density lipids (LDL), and its protection against DNA oxidative damage. Hydroxytyrosol, which is widely used in cosmetics and food supplements industries, can be purchased as an olive oil extract that contains low concentration of hydroxytyrosol besides other polyphenols. The price and low natural abundance of hydroxytyrosol make alternative synthetic sources very attractive. In this research, a novel method for the synthesis of pure …

Landscape-Scale Geophysics At Tel Shimron, Jezreel Valley, Israel, Rachel Grap Aug 2017

Landscape-Scale Geophysics At Tel Shimron, Jezreel Valley, Israel, Rachel Grap

Electronic Theses and Dissertations

Ground-penetrating radar (GPR) and magnetometry were used at Tel Shimron, an archaeological site in Israel’s Jezreel Valley. GPR primarily measures electric properties while magnetometry measures magnetic properties, making them complementary methods for subsurface prospection. Magnetometry can be collected and processed quickly, making it an ideal landscape-scale reconnaissance tool. It takes more time to collect, process, and interpret GPR data, but the result is a higher resolution dataset. In addition, GPR often works better than magnetometry in desert environments such as the Jezreel Valley. Conventional wisdom suggests that GPR should not be used as a landscape-scale reconnaissance tool unless there is …


The Effects Of Employment On Recidivism Among Delinquent Juveniles, Leigh Kassem Aug 2017

The Effects Of Employment On Recidivism Among Delinquent Juveniles, Leigh Kassem

Electronic Theses and Dissertations

Current research indicates an association between intense adolescent work (twenty hours or more per week) and delinquent behavior. It has been widely speculated that this relationship is spurious, occurring only as a result of other factors which are common to both offending and intense employment. The current study attempts to fill a gap in the literature by utilizing the Pathways to Desistance dataset to examine the evolution of the relationship between work and self-reported offending in a longitudinal sample of juvenile offenders. Work intensity and consistency, social capital, and expectations for success were analyzed as potential predictors of recidivism or …
