Community College Faculty's Attitudes And Self-Efficacy With Literacy Instruction In The Disciplines, Kristen H. Gregory, Linda Bol, Thomas Bean, Tony Perez

Educational Leadership & Workforce Development Faculty Publications

Many community college students are entering college-level courses underprepared for the literacy skills required to be successful. Faculty are considered experts in their disciplines, yet are often not trained in pedagogy and literacy instruction (Furco & Moely, 2012; Moje, 2008; Tsui, 2002). We developed a questionnaire to measure faculty's (n = 231) perceptions of their role, level of self-efficacy, and classroom practice in regard to discipline- specific literacy instruction. We analyzed data using exploratory factor analysis, t-tests, and analysis of variance. The findings show that faculty have marginally positive perceptions and self-efficacy regarding incorporating discipline-specific literacy instruction in their courses. …

Hysteretic Behavior Of Thin-Walled Steel Tubular Columns Under Constant Axial Force And Cyclic Lateral Loading, Qusay A. Al-Kaseasbeh

Theses and Dissertations

Thin-walled steel tubular bridge piers (column refers to “bridge pier” in the subsequent text) with either circular and square box cross sections are becoming an increasingly attractive choice as cantilever bridge piers in severe earthquake regions due to their architectural, structural and constructional advantages. However, thin-walled steel tubular columns are vulnerable to local buckling, global buckling or interaction between both under extreme loading events such as strong earthquakes. This buckling results in a significant strength and ductility degradation, which eventually leads to an early and full collapse of the thin-walled steel tubular columns. The work presented in this dissertation investigates …

Synthesis And Characterization Of Quasi-Two-Dimensional Chromium Sulfides, Furkan Muhammet Altincicek

Theses and Dissertations

Transition metal dichalcogenides (TMDs) are atomically thin semiconductors of the type MX2 with M being a transition metal and X being a chalcogen atom. TMDs have recently attracted considerable attention because of their novel electronic and optical properties. Many TMDs have been studied except CrS2 because of the challenges in its synthesis. However, the most stable form of chromium sulfides, Cr2S3, chromium (III) sulfide, has been known to exhibit novel properties. For this reason, we studied the possibility of synthesizing thin Cr2S3 to mimic CrS2. We synthesized single phase Cr2S3 in vacuum sealed quartz tubes. The synthesis takes about 5 …

Theses and Dissertations

Lithium ion batteries present a promising solution for energy storage applications which can be utilized to make green energy generation from sources such as wind and solar more practical. Lithium iron phosphate is an attractive battery cathode material due to its long lifespan, safety and stability, and environmentally friendly chemistry. One shortcoming of lithium iron phosphate is its inherently low conductivity, which is commonly overcome through the addition of conductive carbon. Graphene is a two-dimensional nanomaterial comprised of a single layer of carbon atoms, which displays excellent electrical, thermal, and mechanical properties. Commercial incorporation of graphene into battery electrode materials …

United States Coast Guard Aviation Safety: Relationship Between The Safety Survey And The Extent Of Hazard Reporting, James Cooley

Theses and Dissertations

Aviation safety outcomes, such as mishaps, are a product of an aviation organization’s safety culture (Reason, 2008; Reiman & Pietikäinen, 2012). Safety cultures should be assessed in order to improve an organization’s state of safety (Adjekum et al., 2015; Cooper, Collins, Bernard, Schwann, & Knox, 2019; Wiegmann, Zhang, von Thaden, Sharma, & Gibbons, 2004). Questionnaires are one of the best ways of obtaining information about an organization’s safety culture (Wiegmann et al., 2004; Wald, Gray, & Eatough, 2018). Additionally, the extent to which aviation hazards are reported (hazreps) serve as an indicator of the health of an aviation Safety Management …

Determination Of Maximum Scour Depth For Spur Dikes Based On A Validated Two-Dimensional Hec-Ras Model, Mathew Lee Cox

Theses and Dissertations

The introduction of spur dikes into a river flow field can have many far-reaching positive effects on the stability of a river channel. While the flow velocity directly at the spur dike tip or crest may increase, a large embayment area downstream of the spur dike will form with reduced flow velocities. Due to the increase in flow velocity at the spur dike, a scour hole will form. Scour is the leading cause of failure of hydraulic structures. In the past many hydraulic structures were tested by building scale prototype models, this method is very costly and hard to model …

Impacts Of Cold Region Hydroclimatic Variability On Phosphorus Exports: Insights From Concentrations - Discharge Relationships, Tyson Lee Jeannotte

Theses and Dissertations

In Devils Lake ND, a terminal lake in the Northern Great Plains, algae blooms are of great concern due to the recent increase of streamflow and subsequent elevated concentrations of nutrients, particularly phosphorus. To date, very few studies explore P concentration to streamflow relationship in cold region agricultural basins, specially the headwater catchments of the Devils Lake basin. This study gains a better understanding of the impacts of hydroclimatic variation on concentration to streamflow relationships between two headwater catchments (Mauvais Coulee: 1032 km2 and Tributary 3: 160 km2) draining to Devils Lake during the 2016-2018 period. This study presents high-resolution …

Prestige, Status, And Esteem And The Teacher Shortage, Scott G. Klimek

Theses and Dissertations

Perceptions of prestige, status, and esteem of the teaching career were explored in this study. The population consisted of 1,127 high school seniors and college undergraduates. The study included 51 statements where participants rated their perceptions of teaching’s prestige, status, and esteem on an 8 point Likert scale. The data was factor analyzed, and the results identified that the perceptions of teaching’s prestige consisted of financial and image perceptions. A descriptive analysis found that high school senior and college undergraduate perceptions of teaching’s financial component of prestige (M = 9.99, SD = 2.90) and esteem (M = 10.42, SD = …

Enhancing Liquid And Gas Separation With Activated Carbon Mixed-Matrix Membranes, Jeremy Lewis

Theses and Dissertations

Mixed matrix membranes are one class of membrane material that are an especially promising separation media. By adding a particle phase to a matrix phase, multiple mechanistic pathways become available that are not present in pristine organic or inorganic membranes. These pathways can be exploited to better enhance separation performance for a variety of applications.

This research has focused on a specific mixed matrix membrane, which contains bio-derived activated carbon particles in a polysulfone matrix. In proper selection of activating agent, this research has shown that the surface functional groups of the activated carbon are highly influenced. This can lead …

Trypanosoma Cruzi Trypomastigote Glycosylphosphatidylinositol-Anchored Mucins And A Synthetic Alpha-Gal-Containing Neoglycoprotein As Potential Biomarkers And Vaccines For Chagas Disease, Igor Leandro Estevao

Open Access Theses & Dissertations

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected tropical disease that kills or permanently disable thousands of people annually. About 6-8 million people are estimated to be infected worldwide. Although many efforts have been made for the development of an effective immunotherapy, currently there is no vaccine to prevent or treat CD in humans. Despite their toxicity, the two current drugs for CD, benznidazole (BZN) and nifurtimox (NFX), have medium-to-high efficacy in the chronic stage of the disease and could save or improve the lives of thousands of patients. However, negative seroconversion in treated patients, as …

Assessment Of Point Of Use (Pou) Systems For Reducing Health Risks Associated With Drinking Water Along The U.S.-Mexico Colonias In The Paso Del Norte Region, Varinia Viridiana Felix Parra

Open Access Theses & Dissertations

In the Paso del Norte Region along the U.S. Mexico Border, there are more than 5,000 families living in impoverished communities known as colonias that lack access to basic infrastructure services such as a public water system. These depend on hauling trucks that deliver water into their storage tanks. Water storage practices by colonia residents on both sides of the border pose an enormous risk for waterborne disease outbreaks and heavy metal contamination because the water quality can decrease rapidly due to volatilization of the residual chlorine, intrusion of rainfall and air-laden dust. Since connection to centralized water treatment and …

Novel Maximum Entrophy Method For The Average Survival Time Differences Between Two Groups, Joscelyne Guzman - Gonzalez

Open Access Theses & Dissertations

We suggest a Maximum Likelihood estimator for the Average Survival Time Difference between two groups, based on the extra time in which should be added to one group to produce the maximum entropy of the result. The estimator is calculated only from time to event data, does not assume hazard proportionality and provides directly the magnitude of the clinical differences between the groups. Our Monte Carlo simulations show that, even at low sample numbers the estimator is a reliable predictor for the clinical differences between the groups, and therefore can be used to estimate from preliminary data whether or not …

Interactions Of Bacterial Communities With Hydrous Sulfate Minerals In Water-Restricted Gypsic Environments: A Case Study Based In The White Sands National Monument, Brandon Nicholas Lajoie

Open Access Theses & Dissertations

Microbial communities have been commonly found to survive and thrive in arid to hyper-arid gypsic environments that are considered hostile to most other forms of life. The mechanisms through which microbes have conquered these harsh environments remain poorly understood. Here I hypothesize that the microbial communities in water-restricted gypsic settings could benefit in terms of energy and water sources via their interactions with the abundant hydrous sulfate minerals [i.e., gypsum (CaSO4·2H2O)] that build up these niches. Gypsum is of high bio-relevance because its sulfate component may be used as electron acceptor by sulfate-reducing bacteria and the crystallization water may be …

Conductivity Modulation In Strained 2d Transition- Metal- Dichalcogenides Via Micro- Electro- Mechanical Actuation, Aldo Ivan Vidaña

Open Access Theses & Dissertations

In this thesis, strain-induced conductivity modulation in bi-layer molybdenum disulfide (MoS2) flakes is experimentally investigated and modeled. Uniaxial tensile strain in the MoS2 flakes is achieved using a micro-electro-mechanical (MEM) actuator. Conductivity ratios up to 400 are demonstrated. Theoretical predictions of conductivity versus applied voltage in the MEMS-MoS2 device match experimental data reasonably well using only the effective width of the TMDC flakes as the sole fitting parameter. The amount of strain induced in the MoS2 flakes was determined to be as high as 2.7% for one flake using the model fitted to the experiment data. The switching energy required …

Born Again With Trump: The Portrayal Of Evangelicals In The Media, Eun-Young Julia Kim

Faculty Publications

Since Trump’s ascendancy in American politics and his subsequent election, a number of articles have surfaced in the media trying to explain evangelical voters’ support of Trump. This paper analyzes common descriptions and conceptions of evangelicals by identifying recurring descriptions of evangelicals in 110 online articles published in a two-and-a-half-year period surrounding Trump’s presidential campaign and election. The results indicate that the answer to the question as to why evangelicals support Trump resides not so much in their theology, but in their aspirations for America and assumptions of what America should be like. This paper argues that it is crucial …

History Repeats Itself: Some New Faces Behind Sex Trafficking Are More Familiar Than You Think, Mary Graw Leary

Emory Law Journal Online

Society is rightly outraged to see America's dark history of slavery repeat itself in the form of human trafficking. However, society should be equally concerned about the new face of those who support human trafficking: components of mainstream corporate America. A review of the relevant history of antebellum slavery reveals that one reason why antebellum slavery continued as long as it did was because of the support it received from economic interests that benefited directly and indirectly from the exploitation. Sadly, that reality is once again apparent today as human trafficking thrives in the world in part because it is …
