Effects Of Urbanization On The Avian Community Of Oak Woodlands, Axel Rutter

All Student Theses and Dissertations

Continued human population growth leads to further expansion of high-density population centers and agricultural land necessary to sustain them. With this urban expansion comes a myriad of effects on both native habitat and wildlife. In birds, these effects can have a variety of negative impacts on behavior and physical health. Habitat degradation, largely through various forms of pollution, leads to impaired immune responses, increased stress levels, altered behavior, and much more. The wide range of effects impacting wild birds and their habitat can also alter the structure of local communities. Only species that can survive on or adapt to the …

Rights Should Not Vary Based On Offense Severity, Russell L. Christopher

Articles, Chapters in Books and Other Contributions to Scholarly Works

Some constitutional rights of criminal procedure apply unequally, varying based on offense (or punishment) severity. Of these, some vary proportionally, attaching or strengthening as offense severity increases. For example, the Sixth Amendment guarantees the rights to appointed counsel for indigents and jury trial for defendants charged with any felony but only some misdemeanors. In contrast, other rights are inversely proportional. For example, the strength or applicability of some aspects of the Fourth Amendment right against unreasonable searches and seizures and the Eighth Amendment right against excessive bail decrease as offense severity increases. This Article examines whether such rights should vary …

Archaeosine Modification Of Archaeal Trna - A Role In Structural Stabilization, Ben Turner, Brett W. Burkhart, Katrin Weidenbach, Robert Ross, Patrick A. Limbach, Ruth A. Schmitz, Valérie De Crécy-Lagard, Kenneth M. Stedman, Thomas J. Santangelo, Dirk Iwata-Reuyl

Biology Faculty Publications and Presentations

Archaeosine (G+) is a structurally complex modified nucleoside found quasi-universally in the tRNA of Archaea and located at position 15 in the dihydrouridine loop, a site not modified in any tRNA outside of the Archaea. G+ is characterized by an unusual 7-deazaguanosine core structure with a formamidine group at the 7-position. The location of G+ at position 15, coupled with its novel molecular structure, led to a hypothesis that G+ stabilizes tRNA tertiary structure through several distinct mechanisms. To test whether G+ contributes to tRNA stability and define the biological role of G+, we investigated the consequences of introducing targeted …

The discovery of cruciviruses revealed the most explicit example of a common protein homologue between DNA and RNA viruses to date. Cruciviruses are a novel group of circular Rep-encoding single-stranded DNA (ssDNA) (CRESSDNA) viruses that encode capsid proteins that are most closely related to those encoded by RNA viruses in the family Tombusviridae. The apparent chimeric nature of the two core proteins encoded by crucivirus genomes suggests horizontal gene transfer of capsid genes between DNA and RNA viruses. Here, we identified and characterized 451 new crucivirus genomes and 10 capsid-encoding circular genetic elements through de novo assembly and mining of …

Spillover Of Sea Scallops From Rotational Closures In The Mid-Atlantic Bight (United States), Deborah R. Hart, Daphne M. Monroe, Joseph C. Caracappa, Dale Haidvogel, Burton V. Shank, David B. Rudders, John M. Klinck, Eileen E. Hofmann, Eric N. Powell

CCPO Publications

We examined evidence for larval spillover (increased recruitment outside the closures) of Atlantic sea scallops (Placopecten magellanicus) due to rotational closures in the Mid-Atlantic Bight using a 40-year fisheries survey time series and a larval transport model. Since the first closure of the Hudson Canyon South (HCS) area in 1998, mean recruitment in the two areas directly down-current from this closure, Elephant Trunk (ET) and Delmarva (DMV), increased significantly by factors of about 7 and 2, respectively. Stock–recruit plots indicate that low biomasses in HCS were associated with reduced mean recruitment in ET and DMV. Simulations indicate that larvae spawned …

The “Challenge" Of Depletion: Why The Oyster Fishery Is Not Self-Regulating, Eric N. Powell, John M. Klinck, Leanne M. Poussard

CCPO Publications

The possibility that the economics of the oyster fishery impose a self-limitation on overharvesting has been proffered on occasion. The inefficiency of harvesting by the fishery has been evaluated and estimates of the exploitation rate permissible under conditions of maximum sustainable yield have been obtained in previous studies. The question becomes to what extent does the inefficiency of harvest interact with the economics of the fishery to compromise ready detection of overfishing? This study explores the possibility that the constraint of economics on the fishery occurs at oyster exploitation rates that are higher than maximum sustainable yield, leading ineluctably to …

Professional Growth: How Do Cooperating Teachers Grow Through The Experience Of Having A Student Teacher?, Ashton D. Coppley

Doctor of Education Dissertations

Cooperating teachers and student teachers share a unique internship that allows the development of skills for both individuals. The literature states that cooperating teachers can grow from student teachers; however, there are a few sources that state the areas in which this growth occurs. The purpose of this study was to determine if growth or impact happened in the areas of instructional practices, coaching skills, and self-efficacy during the student teaching process. This mixed methods study included a survey, focus group interview, and single interviews to determine whether any change was made. The survey created descriptive statistics, a Pearson correlation …

Mastery Learning: A Mixed-Methods Study Of Teacher Efforts Implementing Key Components Of The Mastery Learning Framework, Lashay Conley

Doctor of Education Dissertations

This study works to assess the degree to which the impact of implementation of Mastery Learning can be described through teacher perception, academic achievement, and student growth. Elementary school teachers in a suburb in North Carolina implemented the Mastery Learning framework. The school’s end-of-grade test scores were above state and district averages but did not meet expected academic growth as identified by the state. These results are an indicator that many of the students were proficient but were not growing at an acceptable rate. Beginning in the 2017 school year, teachers attended professional development training on the framework, processes, and …

A Qualitative Study Of The Impact Of Experiences Of Students With Parents As Their Principal, Teacher, Or Coach, Lori Lynn Brownlee-Brewton

Doctor of Education Dissertations

Many people assume that educators’ children have an easy life in school, since many people at the school level and in the community traditionally hold educators in high esteem. Rarely does anyone explore the added pressure put on this selected class of students to perform for teachers, classmates, and the parent-educator, especially when all are in the same school. Perceptions of belonging have been determined to have important effects on adolescent development, influencing both social and academic outcomes (Baumeister & Leary, 1995; Walton & Cohen, 2007). Educators’ children are often uncomfortable with everyone knowing who their parent is. Students whose …

Exploring The Effectiveness Of A Freshman/Success Academy Program Through The Perceptions Of Educators In An Urban High School, Michelle Pettiford

Doctor of Education Dissertations

The purpose of this qualitative study was to explore the perceptions of educators regarding the effectiveness of an academic success program for ninth- and 10^th-grade students who are at-risk males. The term at risk has often been utilized to describe students who have low academic performance as well as social and emotional concerns observed during the transitioning process from middle to high school. The foundation of this study centered on past and current educational initiatives, achievement gaps, and pedagogical and cultural awareness for at-risk minority students as they entered high school. I used a 2-phase process that included …

Teacher Reflective Practice And The Influence On Student Achievement, Laura Wyatt

Doctor of Education Dissertations

This research study explored in-service teacher reflective practices. Data were collected via survey and interview to answer questions about how teachers define and engage in reflective practice, how teachers develop as reflective practitioners, and how reflective practice influences student achievement. The survey population included 170 elementary and middle level teachers in a school district in the upstate of South Carolina. Student achievement was based upon English language arts and math standardized testing data. Likert items explored the frequency, social context, and modes of reflective practice in which teachers engage. Open-response items provided teachers the opportunity to further describe practices and …

Principal Perceptions: The Impact Of Positive Behavioral Interventions And Supports On Discipline Disproportionality, Courtney K. Johnson

Doctor of Education Dissertations

This study explored the impact of the Positive Behavioral Interventions and Supports (PBIS) framework on discipline disproportionality in an Eastern Virginia school division. Nationally, African American students are suspended and expelled at a much higher rate than their peers (Skiba et al., 2016). This study explored the impact PBIS had on this rate. The work is valuable to those interested in introducing the PBIS framework in their school division or school. A phenomenological, qualitative study was conducted with the first research question using discipline data from the division to track trends. The second research question was answered by interviewing principals …

Widening The Pipeline: Identifying Practices And Structures That Effectively Recruit And Retain African-American Females In Undergraduate Computer Science Programs At Historically Black Colleges And Universities, Martha Haigler

Doctor of Education Dissertations

The underrepresentation of women and women of color in the disciplines of science, technology, engineering, and mathematics (STEM) is of little surprise to those of us who have kept abreast of the statistical data supporting this phenomenon. In order for the United States (U.S.) to remain “economically and globally competitive” (Ong, 2011, p. 32), it needs to increase its “advanced domestic science and technology workforce” (Ong, 2011, p.32). Perhaps, it is not a coincidence that the majority of students attending U.S. colleges are female, and the number of minority students entering college is on the rise. However, when one looks …

Vertical Processes And Resolution Impact Ice Shelf Basal Melting: A Multi-Model Study, David E. Gwyther, Kazuya Kusahara, Xylar S. Asay-Davis, Michael S. Dinniman, Benjamin K. Galton-Fenzi

CCPO Publications

Understanding ice shelf–ocean interaction is fundamental to projecting the Antarctic ice sheet response to a warming climate. Numerical ice shelf–ocean models are a powerful tool for simulating this interaction, yet are limited by inherent model weaknesses and scarce observations, leading to parameterisations that are unverified and unvalidated below ice shelves. We explore how different models simulate ice shelf–ocean interaction using the 2nd Ice Shelf–Ocean Model Intercomparison Project (ISOMIP+) framework. Vertical discretisation and resolution of the ocean model are shown to have a significant effect on ice shelf basal melt rate, through differences in the distribution of meltwater fluxes and the …

Electrotransfer Of Il-15/Il-15rα Complex For The Treatment Of Established Melanoma, Shawna A. Shirley, Cathryn G. Lundberg, Richard Heller

Bioelectrics Publications

Gene electrotransfer (GET) is a safe, reliable, and effective method of delivering plasmid DNA (pDNA) to solid tumors. GET has been previously used to deliver interleukin-15 (IL-15) to mouse melanoma, resulting in long-term tumor regression and the survival of a percentage of treated animals after challenge. To enhance this effect, we evaluated modulating the expression levels of IL-15 and co-expressing its receptor, IL-15Rα. GET was used to deliver plasmids encoding IL-15 and IL-15Rα to established B16.F10 tumors on days 0, 4, and 7. Two delivery protocols that yielded different expression profiles were utilized. Mice that were tumor-free for 50 days …

A License To Kill: The Institutional Failure Of The Legal System To Hold Police Accountable, Eliana R. Fleischer

Honors Theses

In recent years, police shootings of unarmed African American men have become nationally visible. With few exceptions, the police officers involved in those shootings have escaped any criminal penalties. This paper addresses why so few police officers are convicted after shooting unarmed African Americans. Using an interdisciplinary approach, it addresses three aspects of the criminal justice system: prosecutorial power, Supreme Court case law, and jury bias. This paper argues that the legal system is structured to protect police officers from liability, making it unable to deliver justice after on-duty police shootings of unarmed African American men.

Gratitude, Resilience And Post-Traumatic Growth Among Kidney Transplant Recipients, Lillie Credle

Honors Theses

Chronic health conditions, such as end-stage renal disease (ESRD), can produce detrimental physical, psychological, and emotional effects (Schulz & Kroencke, 2015). While transplantation helps to alleviate the physical symptoms, other psychosocial problems can remain. The present study sought to investigate whether organ transplant recipients utilize certain strength-based attributes—gratitude, resilience, and post-traumatic growth—when coping with life post-transplant. This mixed-methods study recruited eight (N=8) kidney transplant recipients, who took part in semi-structured interviews followed by a survey. Though quantitative data was limited due to COVID-19 interruptions, the qualitative data revealed evidence of gratitude, resilience, and post-traumatic growth being used by the participants …

Learning To Check Yourself: Improving Civic Engagement Through Duties, Better Voting Practices, And Combatting Group Loyalty, Katherine Brumund

Honors Theses

This project examines civic engagement. It is divided into three chapters: apathy, voting, and group loyalties. I derive two duties, a duty to care and a duty to reason well, that serve as a framework for community engagement aimed at facilitating moral progress. In the second section the main topic is voting. I argue for strategies to vote well. The third section of this project then focuses on group loyalties. This project uses two duties to frame how to engage with others, proposes a better way to participate civically, and ways to avoid pitfalls associated with group membership.

How To Be A Good Believer: A Multifaceted Defense Of Christian Belief, Cameron Bonsell

Honors Theses

In this paper I will argue that holding Christian beliefs is consistent with intellectual virtues. I must first clarify that holding Christian beliefs does not consist only in the affirmation of certain propositions like “God exists”. This is not to say that affirming certain doctrine is not essential to Christian belief, but this is only part of what it encompasses. When I refer to Christianity and Christian beliefs in this paper, I mean affirming basic religious propositions like “Jesus was the son of God”, but I also take certain practices to be part of Christian belief. For example, spiritual disciplines …

The Effect Of President Trump’S Company-Specific Tweets On Company’S Stocks, Justin Kleczka

Honors Theses

Implementing event-study analysis, I find that President Trump’s tweets about publicly traded companies cause daily abnormal returns of 0.25% in a company’s stock in the same direction as the sentiment of the tweet: positive tweets increase abnormal returns by 0.25% on the day’s end, while negative tweets will cause -0.25% abnormal returns.

Additionally, I find that President Trump’s company-specific tweets increase the daily abnormal trading volume and volatility of a company’s stock by 19%, regardless of tweet sentiment. For abnormal returns and abnormal trading volume, the effects of President Trump’s tweets do not last multiple days after a tweet. However, …

The Electoral College: Size Really Does Matter, Alexander Kirk

Honors Theses

The goal of this paper is to explore and ultimately convince the reader of the merits of the Wyoming Rule method of congressional apportionment as a method for altering the functioning of the Electoral College in United States presidential elections. This is conducted through an analysis of the role that the Electoral College has played throughout the history of American elections, in depth looks at four common proposals for changing or replacing the Electoral College, and finally discussion of the intricacies of the Wyoming Rule and the effects that it would have on American politics.

Troping For Justice And Joy: A Feminist Rhetorical Study Of Women’S Reproductive Health, Claire E. Noppenberger

Honors Theses

Taking my cues from feminist rhetorical studies, and the enactment of the personal as political, my thick description of women’s reproductive healthcare is focused on my own encounters with these rhetorics through a collection of my experiences through various media. This description adopts an autoethnographic attitude to approach these rhetorics “as pluralistic, subjective, personal, and potentially inclusive,” by using my own position and narrative to frame this rhetorical study. Just as feminist rhetorical studies require meta-reflexive awareness, autoethnography requires the acceptance of “responsibility for our subjective lenses through reflexivity.” My thick description uses the metadata of these media, including the …

Estimating Value-At-Risk Of An Unconventional Portfolio, Elizabeth N. Mejía-Ricart

Honors Theses

Since the 2008 financial crisis, interest rates and bond yields have been low all through the recovery and expansion that followed, and they are still low. As a result, more investors have been attracted to US equities, a space of possibly higher returns. However, these returns come with a potential downside: risk of loss. One of the methods to assess this potential downside is value-at-risk (VaR), which gained momentum in the late 1990s. At the time, the market risk amendment to the 1988 Basle Capital Accord required commercial banks with significant trading activities to put aside capital to cover market …

Storytelling For Fundraising: Assessing The Impact Of Personal Stories On Donation Behavior, Kate A. Mccarthy

Honors Theses

In fundraising, some nonprofits have sought to channel the power of personal stories by including them in appeal letters. Are stories an effective tool in soliciting donations? In this study, participants read one of three appeals from an unnamed abortion fund. Two conditions contained a personal story, either an “unapologetic” or a “uncontroversial” narrative, about a woman who underwent an abortion; one condition did not include a story. Participants were then asked questions regarding the appeal and the organization before being given a “bonus” dollar, and offered the option of donating a portion of that to an abortion fund. Results …

Synthesis, Characterization, And Reactivity Of Palladium Proazaphosphatrane Complexes, Adrian D. Matthews

Honors Theses

Palladium-catalyzed cross-coupling reactions provide an efficient pathway to a wide variety of otherwise inaccessible compounds. In this study, the synthesis and reactivity of novel palladium proazaphosphatrane complexes that are believed to be intermediates in C–N cross-coupling reactions are described. Both the fundamental reactivity of these complexes and elementary steps involved in a catalytic process are demonstrated. The catalytic viability of palladium proazaphosphatrane complexes is shown through stoichiometric and catalytic cross-coupling reactions. Our findings support the long-standing hypothesis that proazaphosphatranes are conformationally flexible ligands that stabilize a number of catalytic intermediates.
