Repair-Mediated Duplication By Capture Of Proximal Chromosomal Dna Has Shaped Vertebrate Genome Evolution, John K. Pace, Shurjo K. Sen, Mark A. Batzer, Cédric Feschotte

Faculty Publications

DNA double-strand breaks (DSBs) are a common form of cellular damage that can lead to cell death if not repaired promptly. Experimental systems have shown that DSB repair in eukaryotic cells is often imperfect and may result in the insertion of extra chromosomal DNA or the duplication of existing DNA at the breakpoint. These events are thought to be a source of genomic instability and human diseases, but it is unclear whether they have contributed significantly to genome evolution. Here we developed an innovative computational pipeline that takes advantage of the repetitive structure of genomes to detect repair-mediated duplication events …

"More Real And Less Factual:" Teacher Decision-Making About Place-Based Topics In Rural Secondary Classrooms, Timothy G. Thomas

Faculty Research at Morehead State University

In an age of accountability and tenuous school funding, rural schools are particularly challenged to maintain the institution, contribute to the wider community, and imbue students with local pride. One promising instructional approach is place-based education, students studying the setting in which they live and learn. Participants in this qualitative study were 5 Kentucky teachers who covered issues of regional resource management with students. Participants recognized that curricular mandates affected their planning and deprived students of certain skills for success in school and the real world. In the results of the study, the essential nature of interaction between school and …

The Effects Of Stream Discharge And Channelization On The Macroinvertebrate Community In A Semi-Arid Landscape, Thomas L. Kennedy

Biology ETDs

The Middle Rio Grande is the second largest watershed in the southwestern United States and is a vitally important component for the biodiversity in the region. Similar to many other rivers, the MRG is a temporally dynamic system that unfortunately, has been subjected to river regulation. As a result, the river has become channelised in many reaches disconnecting it from the surrounding floodplain. The effects of river regulation on the MRG and its surrounding riparian zone were largely unknown. I tested three main hypothesis with regards to the macroinvertebrates in the MRG: 1) Does flow variability structure the aquatic macroinvertebrate …

Controls On Microbial Community Structure In Thermal Environments: Exploring Bacterial Diversity And The Relative Influence Of Geochemistry And Geography, Kendra Renee Mitchell

Biology ETDs

Community wide molecular surveys have revealed incredible hidden phylogenetic and metabolic diversity in microbial habitats. We have conducted the first microbial survey of Yellowstone National Park thermal environments, sampling 103 communities from across the park and across the range of conditions found. Yellowstone is particularly suited for this type of research because of the large number and wide variety of thermal springs, which are naturally occurring chemostats enabling examination of the factors that control microbes and drive community structure. In addition to samples for molecular microbial analysis, we collected water for extensive geochemical analysis in order to begin to deduce …

Investigation Of Photophysical And Photochemical Processes In Conjugated Polymer Nanoparticles By Single Particle And Ensemble Spectroscopy, Craig Szymanski

All Dissertations

Single molecule imaging has emerged as a powerful tool in a range of applications, but the field is limited by a lack of fluorescent probes with sufficient brightness and photostability for many demanding applications such as tracking of single biomolecules in cells and tissues at video rate with 1 nm spatial resolution. Conjugated polymers hold great promise as a solution to these issues, with a high density of π electrons and variety of chemistries, allowing efficient and tunable absorption of light. This dissertation describes the development and characterization of a novel type of nanoparticle composed of conjugated polymer called CPdots. …

Migration And Mixing Between Populations In Disease Models, David Burger

Theses, Dissertations and Culminating Projects

The goal of this thesis is to model the spread of disease between populations and find ways to prevent its continued epidemic. This thesis studies disease spread as a function of migration in epidemiological models. The models are constructed using the compartmental approach, and we compare discrete and continuous time approximations. In the discrete model, we will look at ways that induced migration can cause an epidemic case to turn into a dieout case. It will be shown that migration can only effect the size of an outbreak, but cannot create or destroy one. For the continuous cases, we will …

Are Developmental Math Courses Being Offered At The Appropriate Time Of Day To Optimize Student Success?, Ralph Cox

Mathematics Graduate Theses

This research paper will identify if a relationship exists between success in pre-requisite developmental math courses and the time of day that the course is offered for students enrolled at a rural community and technical college in northwestern Minnesota. The ACCUPLACER Arithmetic test was administered originally during new student orientation and then, again, at the completion of pre-requisite developmental Math Foundations courses. Paired Pre- and Post- Test data was gathered over seven years, from 2002 to 2009, for a total of 268 students (n=268). The data was then evaluated using one-tail two-sample T-tests assuming unequal variances to determine if a …

Anti-Inflammatory Activity Of Calotropis Gigantea And Tridax Procumbens On Carrageenin-Induced Paw Edema In Rats, S. Awasthi, M. Irshad, M. K. Das, S. S. Ganti, Moshahid A. Rizvi

Ethnobotanical Leaflets

The anti-inflammatory activities of extract of Calotropis gigantea R.Br. and Tridax procumbens Linn., were assessed on carrageenin-induced paw edema along with standard drug, Ibuprofen. The Ibuprofen significantly reduced paw edema at the dose of 200mg/Kg bw orally. The oral administration equi-effective dose (ED50) of C. gigantea (600mg/Kg bw) and T. procumbens (400 mg/Kg bw) individually revealed about 20-35% more activity than the one rendered by administration of 50mg/Kg bw of Ibuprofen. The effect of C. gigantea and T. procumbens along with various dose regimen of Ibuprofen showed greater anti-inflammatory activities than the Ibuprofen alone.

Qualitative And Quantitative Analysis Of Clerodendron Colebrookianum Walp. Leaves And Zingiber Cassumunar Roxb. Rhizomes, S. Majaw, J. Moirangthem

Ethnobotanical Leaflets

This article describes simple methods for performing qualitative and quantitative analysis of Clerodendron colebrookianum leaves and Zingiber cassumunar rhizomes. The distribution of the main active principles (phlobatannins, flavonoids, alkaloids, saponins, tannins, terpenoids, steroids, glycosides and anthraquinones) in C. colebrookianum leaves and Z. cassumunar rhizomes were assessed. Both the plant materials were found to contain all the above components except for the absence of anthraquinones in both Z. cassumunar rhizomes and C. colebrookianum leaves, and absence of phlobatannin and glycosides in C. colebrookianum leaves. The importances of the distribution of these chemical constituents were discussed. This study provides scientific method to …

The Effectiveness Of Institutional Intervention At Minimizing Demographic Inertia And Improving The Representation Of Women Faculty In Higher Education, Amanda V. Bakian

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Across all science and engineering disciplines, women currently receive 46% of the doctoral degrees granted annually. Despite gains in doctoral degrees earned by women over the past 30 years, they remain under-represented among full time tenured /tenure-track science and engineering faculty compared to their presence among degree recipients. The inequality gap is widest among full professors at 4 year research universities where women account for a mere 16% of all S&E full time full professors. Multiple hypothesis have been proposed to account for women's under-representation relative to men including those based on human capital/economic theory, feminist theory, innate biological gender …

The Highlands of Roan Mountain best exemplify that which is rare and unique within high elevation communities of the Southern Appalachian Mountains. The Roan Highlands are protected through a landscape-level conservation initiative originally established by the Southern Appalachian Highlands Conservancy (SAHC) and the U. S. Forest Service (USFS) in 1974. The Roan massif rises more than 6,000 feet above mean sea level and straddles the border of North Carolina and Tennessee in the Pisgah and Cherokee National Forests, respectively. Among its unique aspects, the Roan supports at least 800 known plant species, 27 rare plant communities, and 33 federally or …

Cobaltacarborane-Phthalocyanine Conjugates: Syntheses And Photophysical Properties, Hairong Li, Frank R. Fronczek, M. Graça H. Vicente

Faculty Publications

Syntheses of two new cobaltacarborane-phthalocyanine conjugates, one anionic (Pc 6) and one zwitterionic (Pc 7), were accomplished via cyclotetramerization of the corresponding cobaltacarborane-substituted phthalonitriles (4 or 5) with excess phthalonitrile in quinoline. X-ray structures of two phthalonitrile precursors (2 and 3) were obtained and are discussed, and the absorption and emission properties of the two cobaltacarborane-phthalocyanine conjugates in several solvents were investigated. The anionic conjugate 6 exists mainly as a monomer in polar organic solvents and has fluorescence quantum yields in the region 0.2-0.3. The zwitterionic conjugate 7 aggregates in solution and displays lower quantum yields ∼0.1 in organic solvents. …

Changes In Composition Of Culturable Bacteria Community In The Gut Of The Formosan Subterranean Termite Depending On Rearing Conditions Of The Host, C. Husseneder, J. M. Berestecky, J. K. Grace

Faculty Publications

The hindgut of feeding termites that feed on wood and litter contains a diverse population of bacteria and protists that contribute to the carbon, nitrogen, and energy requirements of the termite. For understanding the ecological balance in the termite gut, detailed knowledge about the composition of the microbial gut flora is imperative, i.e., the numbers and relative proportions of the microbial taxa and the variability in the microbial composition among different termite colonies and living conditions of termites should be described. Therefore, we isolated and enumerated eight bacterial morphotypes from the gut of the Formosan subterranean termite, Coptotermes]]formosanus Shiraki. Five …

Interpreting Facial Expressions: The Influence Of Social Anxiety, Emotional Valence, And Race, Lora Rose Hunter, Julia D. Buckner, Norman B. Schmidt

Faculty Publications

Social anxiety is posited to be linked to interpersonal skills deficits, including accurate interpretation of emotional social cues, such as facial expressions. However, empirical support for an interpersonal skills deficit model of social anxiety is lacking. Studies of information processes indicate that socially anxious individuals may be more accurate at identifying threatening facial expressions in particular. In the present study, undergraduates who self-identified as Caucasian (N = 158) completed a task assessing facial expression accuracy. Relevant parameters such as emotional valence as well as race of the target were assessed. As predicted, socially anxious individuals were overall more accurate at …

The Effects Of Foster Care Residence And Age Of Child On Credibility Of Child Sexual Abuse Allegations, Patricia D. Hartman

Masters Theses and Doctoral Dissertations

Research demonstrates that children who have been sexually abused are at increased risk for further abuse. Children placed into foster care are also at heightened risk for abuse in their foster homes. While much research has been conducted concerning the credibility of children’s sexual abuse allegations, none has examined the believability of allegations of abuse within the foster care system. In the present study, 223 undergraduate psychology students were randomly assigned to read one of six scenarios. Each scenario described a girl (age 6, 11, or 15 years of age) who either resided with her mother and stepfather or foster …

Exploding Anthropocentrism: Understanding Optical Democracy In Cormac Mccarthy's Blood Meridian, Jeremy Kevin Locke

Masters Theses and Doctoral Dissertations

In this study, I will attempt to synthesize the aesthetic and metaphysical conceptions of optical democracy. While several critics contend that the concept of optical democracy influences all of McCarthy’s novels, I will limit this treatment to Blood Meridian. By focusing one this one text, I will be able to move beyond the definitional treatments of this concept offered by previous critics and demonstrate how optical democracy works to produce meaning in two particular subjects explored in the novel: history and race. I will suggest that McCarthy uses optical democracy as an aesthetic technique, as described by Holloway, to abolish …

Determination Of Dispersal Patterns Of The Small-Mouthed Salamander (Ambystoma Texanum) In Eagle Creek Park (Indianapolis, In), Stacey Diane Summitt

Undergraduate Honors Thesis Collection

Urbanization and the increasing threat of habitat fragmentation are contributing to the significant declines in amphibian populations world-wide. Ambystomatid species are particularly susceptible to habitat fragmentation because they migrate yearly across upland forests to their breeding sites. Habitat changes could be altering the genetic structure in these species; however few studies have focused on this topic and more generally, examined the dispersal patterns of Ambystomatids. In 2003, Clark, Cripe, and Stachniw conducted a study on “Metapopulation Structure of Ambystoma texanum in Eagle Creek Park (Indianapolis, IN) and the Potential for Gene Flow.” They hypothesized that distance limits the dispersal of …

A Dash Of Sufferage Spice: Rural And Urban Ethnicity Construction In The Transnational Women's Suffrage Movement, Anna M. Peterson

Theses and Dissertations

The women's suffrage movement in Europe and the United States led to female enfranchisement in much of the West in the early twentieth century. Suffrage historiography, however, places too much emphasis on a middle-class history of urban white women's struggle to win the vote. This traditional scholarship not only lacks a thorough class-based analysis but also fails to examine ethnicity's role in the American women's suffrage movement as well as larger transnational connections.

Research on the construction of Norwegian ethnicity and its corresponding influence on Norwegian-American support of women's suffrage contributes to filling this historiographical gap. In addition, the influence …
