An Invasive Species As A Threat To Native Biodiversity: Larval Competition Between Native Anurans And An Invasive Treefrog, Mckenzie Wasley

Electronic Theses and Dissertations

Cuban Treefrogs (Osteopilus septentrionalis) are established in Florida and Louisiana and have invasive potential further westward, possibly impacting native anurans at multiple life stages. In anurans, competition at the larval stage can decrease adult fitness through slower development and smaller size at metamorphosis, ultimately decreasing recruitment rates. To examine the potential impacts of O. septentrionalis at the larval life-history stage, I quantified activity levels and growth of their tadpoles and those of two anurans native to eastern Texas: Green Treefrogs (Hyla cinerea) and Gulf Coast Toads (Incilius nebulifer). Tadpoles of the three species were …

A Qualitative Study Of The Social Emotional Needs Of Newly Arrived Immigrant Secondary Students In One Texas High School, Janie Snyder

The U.S. Department of Education reported that newly arrived immigrant students are welcomed to classrooms in public schools, and recent data revealed that more than 840,000 immigrant students occupy American classrooms. Immigrant students may demonstrate high aspirations and hope for a good public education however, some experiences bring about isolation, anxiety, and oppression, demonstrating a critical need for a caring and equitable environment. This qualitative case study utilized interviews with newcomer students to determine the social-emotional impact of the lived experiences of newly arrived immigrant students …

Through The Devil's Mirror: The Villain And The Sinthomosexual As Manifestations Of The Death Drive, Andrew Markus

Electronic Theses and Dissertations

Lee Edelman’s No Future: Queer Theory and the Death Drive (2004) offers a model for reading queer sexuality and societal place very much in line with that which begins to emerge in early Gothic literature, including Matthew Lewis’s The Monk: A Romance (1796). The Gothic villain aligns with Edelman’s sinthomosexual to illustrate a pattern of victimization and retaliation which results in both the villain and sinthomosexual’s persistent abjection from the social order. However, a close reading of Lewis’s narrative for its depiction of psychological trauma rooted in sexual expression suggests that this queer negativity is not the sum total of …

Tree Canopy Effects On Roof-Harvested Rainwater In East Texas, Kimberly Gamez

Electronic Theses and Dissertations

Nine experimental metal roofs with rainwater harvesting systems were constructed and water quality parameters were measured in 2016-2017 in order to evaluate the effects of arboreal overhang on roof-harvested rainwater quality collected in East Texas.

Characterizing Patterns In Texas Gulf Coast Beach Dune Plant Species Composition, Cody Foster

Electronic Theses and Dissertations

Regional vegetation patterns of Texas beach plant communities were analyzed using cluster analysis, ANOSIM, SIMPER, NMDS, and ISA for fives zones representing the foredune complex of twenty Gulf Coast beaches. ANOVA revealed that zones differ in terms of percent bare sand, percent vegetative cover, and species richness. Cluster Analysis, ANOSIM, and SIMPER results indicate that Texas beaches can be divided into northern and southern regions based on differences in species composition of plant communities. Indicator Species Analysis (ISA) indicates that northern beaches are characterized by the presence of Rayjacksonia phyllocephala, Ambrosia Strophostyles, Ambrosia psilostachya, and Panicum amarum …

To Reach The Unreachable Stars: Reexamining The Shared Arthurian Vision Of C. S. Lewis's Science Fiction Trilogy And Raymond Chandler's Marlowe Novels, Hollis Thompson

Electronic Theses and Dissertations

Although Raymond Chandler and C. S. Lewis seem to be a rather strange pairing, the ways in which they both borrow from Arthurian literature and use the myth to speak to their cultural moment are strikingly similar. Following T. S. Eliot’s use of the Grail quest in The Waste Land (which set a standard for the use of such material in Modern literature), these authors use Arthurian elements as a means of exposing hidden connections between the fragments of the literary past and the present within Chandler’s Marlowe novels and Lewis’s science fiction trilogy. Both men present Western identity as …

The Experience Of Friendship Between Individuals With And Without An Intellectual Disability., Rebecca Clark

Electronic Theses and Dissertations

Practitioners and researchers are concerned about the limited social inclusion and social networks of individuals with an Intellectual Disability (ID) (Amado, 2014; Bigby & Craig, 2017; Hall, 2010; Hardman & Clark, 2006; Knox & Hickson, 2001; McConkey & Collins, 2010; Tipton, 2011). Friendships between those with and without an ID are viewed as opportunities for greater inclusiveness with and connection to the mainstream society (Amado, 2014; Bigby & Craig, 2017; McConkey & Collins, 2010). However, little is known about the development of friendships between those with and without an ID. The purpose of this study was to fully explore the …

The Utilization Of Metal-Ligand Cooperativity For Electrocatalytic Reduction And Catalytic Hydration., Steven Cronin

Electronic Theses and Dissertations

Small molecules are building blocks for developing larger materials. These small molecules could be extremely small, such as hydrogen, or larger such as a nitrile, but their impact on the global economy is massive. This dissertation describes a catalyst for three reactions involving small molecules; 1) the hydrogen evolution reaction, 2) the carbon dioxide reduction reaction, 3) nitrile hydration. The catalyst Zn(DMTH) (DMTH = diacetyl-2-(4-methyl-3-thiosemicarbazonate)-3-(2-pyridinehydrazonato)) use “metal-ligand cooperativity” between the Lewis acid Zn(II) metal ion and an uncoordinated Lewis base nitrogen in the ligand framework to activate substrates. The complex has been analyzed via NMR, UV/Vis, single crystal X-ray crystallography, …

Designing An Autonomous Goods-To-Person Order Picking System: From Storage To Pick., Mina Shekari Ashgzari

Electronic Theses and Dissertations

In recent years, there has been an increased growth in e-commerce, which is a special case of a business-to-customer model. Among all the operations for fulfilling online orders, order picking has been the concern of many researchers and practitioners in the field of warehousing and material handling. This is due to very different technical assumptions and service expectations for online retailers compared to the case of business-to-business models. The most fundamental change in order processing, imposed by business-to-customer models, is shipping individual items or “eaches,” instead of cases and pallets, which is typical of business-to-business models. As a result, the …

Malaria, Microbes, And Mice: The Role Of The Gut Microbiota On The Immune Response To Plasmodium Infection And The Treatment Potential Of Microbiota Modulation., Morgan L. Waide

Electronic Theses and Dissertations

Plasmodium infection leads to over 200 million cases of malaria and 400,000 deaths worldwide each year. These deaths are largely in children under the age of five and pregnant women [1]. Caused by transmission of Plasmodium parasites by the female Anopheles mosquito, malaria poses a risk for over 40 percent of the world’s population [1]. Despite worldwide efforts to eradicate malaria leading to a decrease in malaria-associated mortalities in the early 2000s [2], growing resistance to the available antimalarials and the lack of an effective, long-lasting vaccine has caused this decrease to plateau in recent years [1, 3-6]. Furthermore, malaria …

The Impact Of A Digital Intervention On Perceived Stress, Resiliency, Social Support, And Intention To Leave Among Newly Licensed Nurses: A Randomized Controlled Trial, Lisa Concilio

Electronic Theses and Dissertations

The nursing shortage has been deemed a public health crisis with the turnover rate of newly licensed nurses (NLNs) growing (Robert Wood Johnson Foundation, 2014). One out of five NLNs are leaving the profession due to work dissatisfaction and feelings of inadequacy (National Academy of Medicine, 2017). NLN attrition during the first year of hire has been associated with feelings of overwhelming stress and decreased sense of support which negatively impact patient safety (Spence Laschinger et al., 2016). As seasoned nurses are attempting to retire amidst a nursing shortage (American Association of Colleges of Nursing, 2018), NLNs require more support …

Delineating Of The Utica Shale/Point Pleasant Formation Play System To Determine Influence Of The Precambrian Basement In Northeastern Ohio, Jarrod R. Bridges

Electronic Theses and Dissertations

The Utica Shale/Point Pleasant Formation system has recently become a highly developed unconventional target for oil and natural gas production, leading to an increased desire for knowledge of the controls on deposition of this system. Precambrian basement features have long been known to affect deposition of older strata near these features across Ohio, but the effects of far field tectonics is not fully agreed upon. Precambrian faults and lineaments are known to exist and have been mapped, but are thought to have ceased their influence on deposition by the time of the Knox unconformity during the Cambrian. In the case …

An Economic Analysis Of Using Retired Vessels To Create Artificial Reefs In Costa Rica, Josué González

Electronic Theses and Dissertations

ABSTRACT

The Republic of Costa Rica is a Central American country with only 0.03% of the world’s landmass, but 5% of the world’s biodiversity, making it a leading ecotourism destination. Ecotourism is one of the main sources of revenue for the country, but the degradation of coastal reefs has resulted in a significant loss of financial income for developing areas. As a result, many of these areas are searching for methods to revert the degradation of coral reefs.

The Functions And Uses Of The Marker “Bita:ʕ” In Egyptian Arabic: A Corpus Analysis: Discourse And Vagueness Functions, Asmaa Taha

Electronic Theses and Dissertations

Discourse markers are used considerably in Egyptian colloquial Arabic, yet few studies examine them in colloquial Arabic. A mixed-method research design adopting a descriptive corpus-based approach is used to better understand the communicative discourse and vagueness functions of the words bita:ʕ, bita:ʕa, and bitu:ʕ in Egyptian Arabic discourse. This study also highlights the collocational behavior of bita:ʕ, bita:ʕa, and bitu:ʕ as well as their colligation patterns. A correlation is found between colligation patterns of the markers bita:ʕ and its variants and particular discourse and vagueness functions in context. Additionally, the study investigates the morphosyntactic phenomenon in which bita:ʕ has …

Privacy In Multigenerational Homes Before And Amidst Covid-19, Jennifer Luque

Electronic Theses and Dissertations

Multigenerational households in the United States are more prevalent now than they have been in the last forty years. In part, aging, illness, job loss, saving money, and even tradition are factors that contribute to the idea of multiple generations living together in one home. Given the health of the individuals, size of the home, and number of dedicated bedrooms and bathrooms, living multigenerational can have both positive and adverse effects. Many family groups fall into the category of multigenerational living. However, this study investigates the relationships between adults and senior family members in terms of privacy in the home. …

Teacher Perceptions Of Collegial Collaboration In An Academy Structure., Kristy Marie Field

Electronic Theses and Dissertations

Collaboration in is an often researched, many-named concept with a definition which has historically been unclear. What one calls collegiality another may call teacher teaming and yet another may refer to as professional networking. Scholars agree effective teacher collaboration can lead to higher student achievement, teacher efficacy, and teacher retention. However, as elusive as an agreed-upon definition may be an agreed-upon structure that fosters an effective version of this collaboration. When Ford began the Ford Next Generation Learning initiative, they embarked on the path to developing a school model that focused on school and community partnerships to support long-term, transformational …

Language Ability And Concurrent Predictors Of Pragmatic Communication In Children With Williams Syndrome Or 7q11.23 Duplication Syndrome., Amanda G. Harmon

Electronic Theses and Dissertations

The present project examined the language abilities of children with two reciprocal neurogenetic disorders: Williams syndrome (WS), which is caused by a hemideletion of 26 - 28 genes on chromosome 7q11.23, and 7q11.23 duplication syndrome (Dup7), which results from an extra copy of the same 26 - 28 genes. Appraising the language of children with WS and Dup7 helps in understanding the communication difficulties they encounter. There were three research goals.
