Conservation From The Bottom-Up: Human, Financial, And Natural Capital As Determinants Of Resilient Livelihoods In Kigoma Rural, Tanzania, Yared J. Fubusa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rhetoric of "community-based conservation" has gained prominence among development specialists and environmentalists, yet such projects are often implemented from the top-down in Africa. This dissertation contends that only a bottom-up approach can foster resilient livelihoods and environmental stewardship.

This study focused on determinants of household resilience within a poverty-stricken agricultural community near Gombe Stream National Park (GSNP) in western Tanzania. The research purpose was to explore: 1) relationships between villagers and GSNP management; 2) how groups and individuals view priority livelihood problems and solutions; 3) various attributes of households; and 4) perceived trends for household resilience and how these are …

Worry And Rumination: Measurement Invariance Across Gender, Janet A. Carter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study examined the factor structure of the Penn State Worry Questionnaire (PSWQ), the Student Worry Questionnaire-30 (SWQ-30), the Anxious Thoughts Inventory (AnTI), the Ruminative Responses Scale (RRS), and the Rumination-Reflection Questionnaire (RRQ). The present study also examined the measurement invariance between men (n = 186) and women (n = 316) in a university sample. Different models for each measure were identified through a review of the literature, and the models were examined through confirmatory factor analyses. The best-fitting models for each measure were retained for subsequent model modification to improve fit and for invariance testing across …

Can The "Peasant" Speak? Forging Dialogues In A Nineteenth-Century Legend Collection, William Pooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The folklore collections amassed by Jean-François Bladé in nineteenth-century southwestern France are problematic for modern readers. Bladé's legacy includes a confusing combination of poorly received historical works and unimportant short stories as well as the large collections of proverbs, songs, and narratives that he collected in his native Gascony. No writer has ever attempted to study any of Bladé's informants in detail, not even his most famous narrator, the illiterate and "defiant" Guillaume Cazaux.

Rather than dismissing Bladé as a poor ethnographer whose transcripts do not reflect what his informant Cazaux said, I propose taking Bladé's own confusion about authenticity …

Transportation Network Resiliency: A Fuzzy Systems Approach, Nayel Urena Serulle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Every day the dependence on transportation grows as local, regional, national, and international independence increases. Resilient transportation systems are needed to secure the highest possible level of service during disruptive events, including natural and man-made disasters. Because of limited resources, decision makers need guidance on how, when, and where to invest to improve resiliency of their networks. The research objective is to develop a method to assess and quantify resiliency, at pre-event conditions, using a fuzzy inference approach. This research expands previous work, refining key variable definitions, adjusting model interactions, and increasing transparency between metrics. This thesis presents the method …

Environmental And Developmental Indicators In Early Childhood: Relations To Second-Grade Reading Comprehension, Gina A. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reading success has been linked to high school completion, future job success, and future generations of children who can read. Unfortunately, children who are unable to read on grade level by the end of first grade are at a great disadvantage and unlikely to catch up later. Without the ability to read and comprehend text, all aspects of schooling become progressively more difficult and the challenge of poor reading ability can be so difficult to overcome that many poor readers will not complete high school. For these reasons, it is important to identify early experiences in a child's family environment …

Novel Approaches To Image Segmentation Based On Neutrosophic Logic, Ming Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Neutrosophy studies the origin, nature, scope of neutralities, and their interactions with different ideational spectra. It is a new philosophy that extends fuzzy logic and is the basis of neutrosophic logic, neutrosophic probability, neutrosophic set theory, and neutrosophic statistics.

Because the world is full of indeterminacy, the imperfection of knowledge that a human receives/observes from the external world also causes imprecision. Neutrosophy introduces a new concept , which is the representation of indeterminacy. However, this theory is mostly discussed in physiology and mathematics. Thus, applications to prove this theory can solve real problems are needed.

Image segmentation is the first …

Integrating Digital Technologies In The German Language Classroom: A Critical Study Of The Technology-Integration Experiences Of Three Secondary German Teachers, Stephen Van Orden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

German language teachers are gaining increased access to smart classrooms and digital technologies that offer teachers and students greater access to authentic cultural and language materials and enable more student target language communication. Teaching with technology changes the teaching and learning environment in many ways. Little is known about how integrating technology into the daily German-language-teaching curriculum changes the implicit power structures embedded in all classroom interactions. Because of the central, decision-making role of the teacher, this study uses a critical theory of technology lens to examine the daily technology integration experiences of three secondary German language teachers. This study …

Removal Of Arsenic And Strontium From Aqueous Solution Using Ironoxide Coated Zeolitized Tuff, Nataliya V. Kasimtseva

UNLV Theses, Dissertations, Professional Papers, and Capstones

As world population grows so does the demand for safe drinking water. Meanwhile water resources become increasingly scarce and quality of natural water decreases due to a combination of natural and anthropogenic factors. Industry and agriculture have become a premiere source of hazardous constituents, along with natural processes such as rock weathering and volcanic eruptions. Our ability to remove hazardous constituents from water depends on chosen technology and nature of contaminant. Sorption and ion-exchange have been widely applied for water purification. Natural zeolites have been widely applied in water and waste water treatment as ion-exchangers for removal of harmful contaminants …

Neural Coding Of Temporal Information And Its Topography In The Auditory Cortex, Thomas A. Terleph, Raphael Pinaud

Biology Faculty Publications

The article discusses a study that focused on neural coding of temporal information and topography in the auditory cortex. The quest for a thorough understanding how highly complex stimuli are encoded poses a significant challenge for auditory neurosciences, such as human speech and animal vocal signals. The characteristics of cortical neurons have been attributed to the coding of temporal stimulus which features precise spike timing in the coding and firing rate of repetition sounds.

The collections here have many culturally unidentifiable Native American human remains and funerary objects eligible for repatriation under the provisions of the Native American Graves Protection and Repatriation Act (NAGPRA). The archaeological …

Systematics And Molecular Phylogeny Of Two African Stem Borer Genera, Sciomesa Tams & Bowden And Carelis Bowden (Lepidoptera: Noctuidae), P. Moyal, B. Le Ru, D. Conlong, D. Cugala, B. Defabachew, T. Matama-Kauma, B. Pallangyo, J. Van Den Berg

All Peer-Reviewed Publications

Currently, the systematics of the African noctuid stem borers of the subtribe Sesamiina, which include major pests of cereals, is confused. In addition, their ecology is poorly known, as are the factors influencing their evolution. In this paper, we address these shortcomings for two genera of the Sesamiina, Sciomesa Tams & Bowden and Carelis Bowden. Mixed Bayesian phylogenetic analysis, which included their host plants and two mitochondrial genes, showed the genus Sciomesa to be polyphyletic. Two new genera were created, Pirateolea and Feraxinia. The genus Carelis proved to be paraphyletic and was subdivided into two sub-genera. The genera Sciomesa, Carelis …

Evolutionary Strategies For Data Mining, Rose Lowe

All Dissertations

Learning classifier systems (LCS) have been successful in generating rules for solving classification problems in data mining. The rules are of the form IF condition THEN action. The condition encodes the features of the input space and the action encodes the class label. What is lacking in those systems is the ability to express each feature using a function that is appropriate for that feature. The genetic algorithm is capable of doing this but cannot because only one type of membership function
is provided. Thus, the genetic algorithm learns only the shape and placement of the membership function, and in …

This cross-continental study explored feasibilities of using Second Life to provide field experiences to pre-service Mandarin teachers in a program of Teaching Chinese as a Foreign Language in Taiwan. This study also investigated pre-service teachers‘ insights of teaching Chinese in such a virtual environment, as well as the difficulties these teachers encountered when integrating Second Life in teaching Chinese. The study found that the more teaching experience the pre-service teachers gained in teaching Chinese in Second Life, …

The Co-Production Of Social Contagion: A Comparative Analysis Of Two Social Networking Sites, Michael Fisher

Student Scholarship

Theories of technology product adoption and diffusion fail to adequately explain social contagion or viral growth. Additionally\, the role of product design in users propensity to use and recommend products is both understudied and poorly understood. To address a vexing gap in knowledge about what explains viral growth\, we conducted ethnographic interviews with technology executives and users of two social networking sites that have experienced dramatically different growth patterns. Our findings reveal that product co-production and user self identity- not product attributes fuel viral growth. Social networking products co-produced by users and providers\, with meaning socially constructed by customers\, permit …

The Conservative Conversation, Heather Hall

Theses and Dissertations - UTB/UTPA

The conservative movement is defined by its ideology as well as its rhetoric. Richard Weaver’s conversion to the Right offers an opportunity to define conservatism and conservative rhetoric through his hierarchy of argumentation, and his examination of Plato’s Phaedrus allows an examination of the speaker’s nature and the nature of rhetoric. Glenn Beck, one of today’s most controversial conservative representatives, also deserves examination for his ideology and rhetoric. Both Richard Weaver and Glenn Beck bear scrutiny as influential members of the conservative movement and the role their rhetoric has in the conservative conversation today.

Trade And Divergence In Education Systems, Pao Li Chang, Fali Huang

Research Collection School Of Economics

This paper presents a theory on the endogenous choice of a country's education policy and the two-way causal relationship between trade and education systems. The setting of a country's education system determines its talent distribution and comparative advantage in trade; the possibility of trade by raising the returns to the sector of comparative advantage in turn induces countries to further diferentiate their education systems and reinforces the initial pattern of comparative advantage. Specifically, the Nash equilibrium choice of education systems by two countries interacting strategically are necessarily more divergent than their autarky choices, although the difference is still less than …

"I Unsex'd My Dress": Lord Byron's Seduction Of Gender In "The Corsair", "Lara", And "Don Juan", Alexis Spiceland Lee

Dissertations

The goal of this project is to posit a theory of how Byron’s texts, specifically through the development of his hero, construct gender and sexuality as styles of seduction that resist easy classification by binary systems. I propose that Byron’s works characterize gender through ironic performances of seduction that, because they reveal that binary structures lack a stable core, dissolve systemic differentiation and thus fatally complicate any attempt to force the individual into rigid categories of gender or sexual identity. Byron’s works deploy seduction as a tactic of ironic representation of both gender and sexual practice that is necessarily multiplicitous …

Recasting Genre In Tennessee Williams's Apprentice Plays, Christina Ilona Hunter

Dissertations

This dissertation investigates Tennessee Williams’s earliest full-length plays, also known as the apprentice plays—Candles to the Sun, Fugitive Kind, Not About Nightingales, Spring Storm, and Stairs to the Roof—by comparing, contrasting and contextualizing them in relation to Daniel Chandler’s generic criteria of drama; namely, narrative, characterization, setting, topics, iconography, and staging techniques. The present study also draws upon an extensive body of scholarship pertaining to genre theory, Williams’s cultural contemporaries, and the historical and psychological backdrop of Depression-era America. In these early plays, Williams diverged sharply from the dramatic generic conventions of his day, manipulating them in new …

Improving Reading Comprehension Through Prior Knowledge Acquisition Via Digital Game Based Learning, Julie Hooker Forbess

Electronic Theses and Dissertations Archive

As a result of the Tennessee Diploma Project, Tennessee students must meet ACT standards in order to achieve high school graduation. However, the reading level of the ACT is beyond that of many average students enrolled in high school. The reading section of the ACT in fact, utilizes many excerpts from classic literature. Classic literature is also included on the reading lists of most school systems across Tennessee as well as the entire country. Many students are unable to connect to the characters and contexts of classic literature because they lack the necessary prior knowledge to make this type of …
