Undocumented Latino College Students And Identity Development: A Qualitative Analysis Of Undocumented Latino College Students’ Movement Towards Developing Purpose, Theresa Danielle Lyon

Masters Theses

Undocumented Latino college students face numerous legal, social, and financial barriers as they attempt to pursue a postsecondary degree. The psychosocial stressors that accompany being labeled as an undocumented immigrant put these students at risk of disengaging from their postsecondary education as they face limited career options and social rejection. Researchers have noted the psychosocial development that occur as students transition to an adult identity, yet little research has been done on how undocumented Latino college students navigate barriers to their identity develop and attempt to define their purpose as not only college students, but members of U.S. Society. This …

Reading Intervention Strategies For General Education Middle School Students: Providing A Space For Teachers To Share Effective Methods, Amy Michelle Baas

Masters Theses

While studies have been conducted to highlight intervention strategies that will help struggling readers, very few of these empirical studies have used middle school aged students as participants. And among those studies which have, the results were based solely on quantifiable data; the opinions of the classroom teachers who work with these students daily cannot be found in these or any of the empirical studies. The purpose of this thesis is to fill this gap by offering a space for middle school English language arts teachers to share effective intervention strategies that they use in their classrooms to help struggling …

The purpose of this study was to examine the impact that a short-term study abroad experience had on student affairs graduate students‟ multicultural competency. The study involved quantitative survey research methods involving 90 former graduate students who participated in the experience between the years 1999-2010 and who were still active in the profession. Participants …

Nerds: A Reclamation Of An Identity, Angiola L. Gabriel

Masters Theses

The term nerd has seen an alteration in usage since it was first used in the 1950s. Originally, nerd carried a negative connotation and people labeled as such were given or had traits such as being overly studious, socially inept, or physically unattractive. However, the term nerd has seen a change in usage since the 1980s; now, the term nerd is seen as a more positive identifier that denotes passion, as well as individuality and intellectualism. There a number of different studies that address nerd identities and cultures in the K-12 educational setting and a broader societal contexts. Yet, there …

An Exploration Of Negative Family Factors And Substance Use Amongst Adolescents: The Lasting Effects Of Family Substance Use, Parental Criminality, And Parental Corporal Punishment, Melissa Ann Murray

Durability Of Sutures Used In Partial Nephrectomy: Tested Across Commonly Used Diameters And Materials Stopped With Lapra-Ty® Suture Clips And Hem-O-Lok® Ligation Systems Under A Given Tension, Nadia Sunny

Masters Theses

The primary healing of soft tissue incision advances in the first fourteen days after surgery. Sutures used to close the incision are terminated with knots to last over this period under tension inside the tissue. However, knots significantly reduce the tensile strength of the sutures, and make the surgery closing time longer and tedious. Suture clips are used to overcome these limitations. It was found in prior researches that sutures slip out of the suture clips, although the manufacturer of the LAPRA-TY® suture clips claims endurance of this product under tension for at least fourteen days. Use of suture clips …

The Depiction Of The Holocaust Within The Theme Of Escape In Michael Chabon's The Amazing Adventures Of Kavalier & Clay, Deirdre Toeller-Novak

Masters Theses

Escape sounds like a ram’s horn throughout Michael Chabon’s The Amazing Adventures of Kavalier and Clay, looming large in the lives of his mostly Jewish characters. Only one, Josef Kavalier, is intimately tied to and escapes the Holocaust which destroys his entire family. The horrors of the Holocaust, however, cast a shadow that hovers over nearly every chapter of Chabon’s 636-page novel. For most of the novel’s other characters, intent on plotting their own escapes, the events of the Holocaust remain 4,000 miles away. Americans, Jew and gentile, politically astute and clueless, laborer and capitalist, prefer to maintain a …

Therefore, understanding vegetation change is of great importance. This study documents changes in tundra vegetation with a focus on understanding the influence of annual differences in weather. Vegetation was sampled using a point frame method on 98 1-m² plots in 2010 and 2013 near Barrow, Alaska. A subset of 30 of these plots was also sampled in 2012 and 2014. Plant encounters were identified to species and grouped into one of the following functional groups: bryophytes, …

Evolution Of Invasive Species In Response To Management: Potential For Herbicide Resistance In Watermilfoil, Lindsey-Ann Louise Schulte

Masters Theses

Herbicides are commonly used to control invasive plants. While agricultural weed scientists have focused on herbicide resistance, little is known about its importance in nonagricultural settings. Hybrid Eurasian watermilfoil (Myriophyllum spicatum x M. sibiricum) is an invasive aquatic plant that is frequently managed with herbicides throughout the United States. In this thesis, I consider the potential for natural populations of this taxon evolving resistance to 2,4-dichlorophenoxyacetic acid (2,4-D), the most commonly used systemic herbicide. Evolutionary change in a trait between generations as a result of selection requires both genetically based variation of the trait within a generation (heritable …

Subcutaneous Tissue Depth Over Intraosseous Infusion Sites In A Cadaveric Model, Megan Marie Glazier

Masters Theses

BACKGROUND: When emergent intravenous access is not available an intraosseous (IO) infusion is performed. To accurately perform an IO infusion, the healthcare provider must precisely palpate and identify the associated anatomical landmark for placement. A thicker layer of subcutaneous tissue over the insertion site can make this process difficult, leading to an increased risk of misplacement. PURPOSE: To relate the subcutaneous tissue depth with body mass index (BMI) and percent body fat in order to better understand IO placement sites in relation to these body composition factors. SUBJECTS: Male and female unembalmed cadavers (n=22) between the ages of 54-95 years …

Evaluation Of Teachers Of Students With Low-Incidence Disabilities, Martyann Guiney

Masters Theses

Current reforms of teacher evaluation systems in the state of Michigan are meant to improve teacher effectiveness, resulting in increased student growth and achievement. However, little research exists to support best practices in the evaluation of special education teachers. The evaluation of special education teachers involves many unique challenges which are especially apparent when evaluating teachers of students with lowincidence disabilities. The tools and processes being proposed by the state are born from research within general education and, consequently, may not be effective in meeting the unique challenges of evaluating special education teachers. The perceptions of special education administrators regarding …

Female Mate Choice In A Mainland Population Of The Strawberry Poison Frog, Oophaga Pumilio, Meaghan Gade

Masters Theses

Sexual selection and female mate choice are driving forces in the evolution and maintenance of biological diversity, and may function in the evolution of many secondary sexual characteristics throughout multiple taxa. Female mate selection has been experimentally shown to drive the evolution of color between the polytypic populations of the dendrobatid frog, Oophaga pumilio, in the Bocas del Toro archipelago in Panama. However, limited studies exist examining biologically relevant female mate choices within a single population. Using analogous experimental arenas from previous studies, females were presented with two males exhibiting phenotypic extremes from within the same population at La Selva …

Children Birth To Age Three With Feeding Difficulties: Systems Level Perspectives Of Supports, Needs, And Interagency Collaboration, Sondra M. Stegenga

Masters Theses

Early identification and treatment of feeding difficulties greatly improves outcomes for young children with feeding difficulties (Williams et al., 2006). However, identifying and addressing feeding difficulties in young children, birth to age three, is complex; requiring not only interdisciplinary collaboration (Arvedson, 2008; Bruns & Thompson, 2010; Lefton-Greif & Arvedson, 2008; Williams et al., 2006) but also interagency collaboration due to the various partners involved in service provision for young children, birth to age three (Individuals with Disabilities Education Act, 2004). When such interagency collaboration is needed, systems level structural supports are shown to levy the greatest impact on outcomes (Tseng …

Assessment Of Northern Bobwhite Survival And Fitness At Felsenthal National Wildlife Refuge, Arkansas, Jacob W. Doggett

Masters Theses

In the West Gulf Coastal Plains (WGCP) northern bobwhite (Colinus virginianus) numbers are declining faster than range-wide averages and such declines have been linked to the consequences of land management within the region. Management for the endangered red-cockaded woodpecker (Picoides borealis) has benefitted northern bobwhite by restoring mature pine-grassland ecosystems in some areas of the region; however, at Felsenthal National Wildlife Refuge, Crossett, Arkansas, USA, the bobwhite population was not increasing despite the availability of seemingly suitable habitat from management for the endangered species. To understand factors that may be affecting bobwhite survival on Felsenthal National …

On such study, that employs a modified GARCH model for estimation, shows that returns associated with the S&P 500 stock index is highest on Wednesday and lowest returns on Monday. The same study shows that volatility is highest on Fridays and lowest on Wednesdays. In this study we investigate if this day-of-the-week effect on returns and volatility is present in the different sectors that constitute the S&P 500 index. The data set used provides daily returns from …

Emi Analysis Of Dvi Link Connectors, Abhishek Patnaik

Masters Theses

"EMI problems are not uncommon in high speed communication systems. As the system clock frequencies increases, so does the challenges in controlling the EMI in such systems. A connector is a very important part of a high speed communication system. Electromagnetic interference (EMI) is found to be tightly correlated to mode conversion: from differential-mode (DM) signals to common-mode (CM) currents and further to antenna-mode (AM) currents on the outside of cables or enclosures. Moreover, in such high speed systems, coupling to an adjacent cable-connector system is not uncommon. It is essential to understand and quantify this coupling path in order …

Effect Of Polymer On Disproportionate Permeability Reduction To Gas And Water For Fractured Shales, Lingbo Liu

Masters Theses

"Large volumes of fracturing fluid are required in shale slickwater fracs, and a considerable amount of polymer friction reducer would remain in microfractures if the polymer has not been broken before gas production. It is of major interest to evaluate the effect of polymer on water/gas flow behavior in the microfractures of shale reservoirs. We fabricated six shale fracture models with different fracture widths and set up a core flooding apparatus to conduct brine/gas-injection experiments before and after polymer treatment. A method by which to calculate the residual resistance factor for gas (F_rr,gas) was defined. The experimental results …

On The Design Of A Nearly Constant-Force Modular Device Based On A Compliant Slider Mechanism, Krutika Karthik

Masters Theses

"Compliant mechanisms derive some or all of their mobility from the deflection of their flexible members. A pseudo-rigid-body model (PRBM) provides a simple and efficient way of modeling and analyzing large deflections in compliant mechanisms. In this work, a partially compliant slider mechanism, composed of rigid and compliant segments as well as rigid-body revolute and prismatic pairs, is considered. In recent works, such mechanisms have been dimensionally synthesized to produce substantially constant-force output over a finite range of input link displacement in an in-line PRBM of a compliant slider mechanism. In this thesis, the current practice of using partially compliant …

On The Dynamic Analysis Of Compliant Mechanisms Based On The Pseudo-Rigid-Body Model, Andrew Christian

Masters Theses

"Compliant mechanisms derive some or all of their mobility from the deflection of flexible members. A pseudo-rigid-body model (PRBM) provides an elegant and simple way of modeling and analyzing traditionally nonlinear large-deflection problems pertaining to compliant mechanisms. In this work, several aspects pertainting to the dynamics of compliant mechanisms are considered. First, dynamic models are derived to predict not only the natural frequency of the large-deflection systems, but also the transient response, using the PRBM approach. A unique multi-stage damping model is developed to determine the transient response in free vibration. Recent works have neglected to consider the transient response …

Changing Hispanic Demographics: The Shift To Democratic Support, Trevor Wayne Schoonover

Masters Theses

While the body of literature concerning voter participation continues to grow there has been a lack of research into the attitudes and behaviors of Hispanics in the United States. To address this disparity in the literature I use the 2012 National Election Study Survey to find support for a Hispanic shift from the right to the left of the political spectrum. I find that Hispanics support the Democratic Party more than Whites on moral values and foreign policy, but not on economic issues. Hispanics are also more likely than Blacks to support the Democratic Party on foreign policy, but not …

A Simpler Route To Building Photochromic Cinnamaldehyde Semicarbazones, Byron R. Ebbert

Masters Theses

Photochromic semicarbazones are an interesting group of compounds that show potential in a broad range of applications, including as a more environmentally friendly replacement for photochromic metal complex compounds. Previous work has shown the feasibility to synthesize photochromic cinnamaldehyde semicarbazones (CSCs) from a benzaldehyde and a protected acetaldehyde Wittig reagent. A new, quicker, and cheaper approach to constructing these CSCs from crotonaldehyde was explored in this research. A three reaction sequence would convert crotonaldehyde to a CSC; first, an allylic bromination of the semicarbazone with N-bromosuccinimide (NBS); second, an Arbuzov reaction to prepare the semicarbazone phosphonate; and finally a condensation …

An Analysis Of Contextual Conditions As First Year Ras Train In And Implement The Phase One Safe Zone Program, Cameron Carrara

Masters Theses

Since the 1990s, safe space initiatives, such as Safe Zone, have been developed on college campuses across the United States as a way of educating participants on LGBTQ-related issues and how to become a better ally/advocate for the LGBTQ community. While little qualitative research has been conducted on safe space initiatives to begin with, there is even less research on the perceptions participants have of these types of programs. Thus, the primary purpose of this study was to analyze the perceptions of the Phase 1 Safe Zone training among first year RAs in the residence halls. A secondary purpose was …

Is Unmitigated Communion Related To Depression And Anxiety?, Brett A. Vacek

Masters Theses

Unmitigated communion is the focus on others to the exclusion of the self. This innate principle has been linked to depression in numerous studies. However, this construct has yet to be linked with rumination, worry, or even social anxiety. This paper reviews the literature on unmitigated communion, including recent studies that have dissected the variable into separate components (UC-self and UC- other) that could help in the identification of its dysfunctional properties. Furthermore, this paper will seek to determine whether unmitigated communion is connected to receiving or providing instrumental or emotional support, and whether this acts as a moderator in …
