Liquid Core Waveguide Sensors With Single And Multi-Spot Excitation, Lynnell Uilani Wai Yee Zempoaltecatl

Theses and Dissertations

Using silicon based microfabrication and materials, a photonic platform, capable of single bioparticle analysis, has been developed. This platform combines liquid and hollow core waveguides on the micron-scale (5 µm x 12 µm) to isolate femtoliter sized sample volumes. Fluorescence excitation and signals in the visible range are directed into and out of the sample volume at an orthogonal angle to maximize signal-to-noise. In order to guide light in a low-index material antiresonant reflecting optical waveguides (ARROWs) were incorporated into the platform. This thesis reveals the development path of these structures over several device generations including innovations in material, geometries, …

Grammar In The Composition Classroom: Rewriting The Tradition, Debra Lynn Reece

Theses and Dissertations

In the last 50 years, the trend in the field of composition pedagogy has turned away from traditional grammar instruction, condemning pedagogical practices that focus on preventing and remediating error. In the early 1960s, Richard Braddock, Richard Lloyd-Jones, and Lowell Schoer invoked the death sentence on traditional grammar instruction: "The teaching of formal grammar has a negligible or, because it usually displaces some instruction and practice in actual composition, even a harmful effect on the improvement of writing" (37-38). Having been enlightened by this scholarship, the field refocused instruction to emphasize elements like writing process, collaboration, modeling, and prewriting, pushing …

Physics: Faculty Publications

The 6He nucleus is an ideal candidate to study the weak interaction. To this end we have built a high-intensity source of 6He delivering ∼1010 atoms/s to experiments. Taking full advantage of that available intensity we have performed a high-precision measurement of the 6He half-life that directly probes the axial part of the nuclear Hamiltonian. Currently, we are preparing a measurement of the beta-neutrino angular correlation in 6He beta decay that will allow to search for new physics beyond the Standard Model in the form of tensor currents. © 2013 AIP Publishing LLC.

Contrast Negation Differentiates Visual Pathways Underlying Dynamic And Invariant Facial Processing, Pamela M. Pallett, Ming Meng

Dartmouth Scholarship

Abstract Bruce and Young (1986) proposed a model for face processing that begins with structural encoding, followed by a split into two processing streams: one for the dynamic aspects of the face (e.g., facial expressions of emotion) and the other for the invariant aspects of the face (e.g., gender, identity). Yet how this is accomplished remains unclear. Here, we took a psychophysical approach using contrast negation to test the Bruce and Young model. Previous research suggests that contrast negation impairs processing of invariant features (e.g., gender) but not dynamic features (e.g., expression). In our first experiment, participants discriminated differences in …

Improving An Outpatient Diabetes Program Telephone Follow-Up Process: Evaluating Its Impact On Glycosylated Hemoglobin Levels, Joan B. Niemczewski

Graduate Theses, Dissertations, and Capstones

Telephone follow-up for diabetes self-management is used to facilitate ongoing support for individuals striving to maintain a healthy lifestyle. With the use of telephone follow-up after Diabetes Self-Management Education (DSME), key concepts can be emphasized and goal reinforcement can occur. When successfully managed, improved glycemic control occurs, as evidenced by reductions in glycosylated hemoglobin (A1C) levels. A review of the literature surrounding this topic and description of a capstone scholarly project utilizing findings from the literature to create an evidence-based telephone follow-up pilot study are included. Findings from this study did not reveal statistically significant reductions in A1C levels with …

Plight Of Black Farmers In The Context Of Usda Farm Loan Programs: A Research Agenda For The Future, Shakara S. Tyler, Eddie A. Moore

Professional Agricultural Workers Journal

Black farmers remain an underdeveloped topic in academic literature. This historical study used a historical research methodology to assess the plight of Black farmers in the context of United States Department of Agriculture (USDA) farm loan programs and offered an array of future research recommendations. We investigated the severity of the plight of Black farmers in the context of USDA farm loan programs with an emphasis on effective and responsive leadership in relation to four elements: 1) legislative initiatives, 2) policy initiatives, 3) USDA structure and delivery systems, and the 4) Pigford v. Glickman class action and consent decree. We …

Community Capital And Local Economic Development Efforts, Andrew A. Zekeri

Professional Agricultural Workers Journal

Actions by local groups and leaders constitute an essential but poorly understood element of many rural economic development efforts. Previous studies suggest that local development efforts can influence community changes, but questions remain about why localities differ in economic development efforts. Drawing upon community capital framework and human ecological theory, the purpose of this research was to examine the effects of community capital on economic development efforts in rural communities. Hierarchical regression results indicate that social capital, cultural capital, built capital significantly predict economic development effort to develop recreation and tourism and human services. Despite that, only built capital and …

The Fate Of Local Food Systems In The Global Industrialization Market: Food And Social Justice In The Rural South, Wylin D. Wilson, Reuben C. Warren, Stephen O. Sodeke, Norbert Wilson

Professional Agricultural Workers Journal

This paper investigates the connection between local food systems, health disparities, and social justice in the rural South. It begins with the relationship between food insecurity and health disparities that disproportionately affect racial and ethnic minority populations, and non-minority women and children. First, we discuss the concept of health disparities within the context of bioethics and public health ethics in order to explore the link between the food system and health as a social justice issue. Second, we define health disparities and discuss how they have historically plagued and disadvantaged racial minority populations. Third, we examine these disparities within the …

The Impact Of Selected Socioeconomic Factors On Asset Building In Rural Communities, Nii O. Tackie, Judith N. Aboagye, Gwendolyn J. Johnson, Millicent Braxton, Latanya Hunt-Haralson, Gertrude D. Wall

Professional Agricultural Workers Journal

The study examined the impact of selected socioeconomic factors on asset building. Using a questionnaire, data were obtained from a convenience sample of 204 participants from several Alabama Black Belt Counties, and analyzed using descriptive statistics and logit analysis. The results showed that a majority (64%) was willing to participate in an asset building program. Of this, an overwhelming majority (at most 70%) wanted to set up a small business; further their education, or purchase a home. In addition, one socioeconomic factor, age, had a statistically significant (p = 0.016) effect on willingness to participate in an asset building …

Collaboration Vs. Individualism: What Is Better For The Rising Academic?, Andrew T. Kemp

The Qualitative Report

In academia, scholarship and research productivity is the lifeblood of success. The question is, “What is the best way to be productive and more forward in an academic career — collaboration or individualism?” Obviously, the final choice is personal. However, for the purpose of this paper, the two sides will be discussed regarding the strengths and weaknesses of each avenue. Recommendations regarding the viability of collaboration and competition will be discussed in relation to personal attributes, career goals, and rank. In addition, a new methodology, tentatively called Layered Narrative, will be piloted with this project

Three Ethical Issues In Narrative Research Of Women Coaches’ Lifelong Learning, Bettina Callary

The Qualitative Report

It is important to reflect upon ethical issues in conducting narrative research beyond what may be considered in Research Ethics Board applications. Ethical issues were identified in a dissertation study that utilized a narrative research approach to explore the process of lifelong learning for five women coaches. Using journal reflections and participant and researcher conversations, three ethical issues are discussed. These issues arose during the process of collecting narratives from participants and in creating narrative analyses of the data. While there exists a broad range of views on narratives, all narrative researchers can benefit from reflecting on ethical issues within …

3d Finite Element Modeling Of Sliding Wear, Rodolfo G. Buentello Hernandez

Theses and Dissertations

This research focuses on the mechanical wear due to the sliding between two surfaces. Currently there is a need to identify and compare materials that would endure sliding wear under these severe conditions. The high costs of the high-speed sliding experiments has prevented the collection of the necessary data required to characterize wear. Simulating wear through Finite Elements (FE) would enable its prediction. This 3D wear model allows one to reasonably predict high-speed sliding mechanical wear. In the aerospace, automotive and weapon industries this model can aid in material selection, design and/or testing of systems subjected to high-speed sliding wear.

Civitas: A Game-Based Approach To Ap Art History, Anna Davis

Theses and Dissertations

To increase student engagement as well as cover the content of Ancient Rome, the author developed a game named Civitas for an AP Art History course. The question driving this research project was, "Will incorporating a game into this Ancient Rome unit increase engagement without sacrificing the academic integrity of the class?" Research about engagement as well as others' success incorporating games into the classroom was examined to determine the benefits and difficulties. Much of the work for this unit came before any teaching occurred: designing all aspects of the game as well as carefully determining how it would contribute …
