Effect Of Maternal Age On Recombination Rate In Drosophila Melanogaster, Christopher Schimmoeller

Honors Projects

Recombination is vital because it adds genetic diversity to a species and has the potential to influence fitness, the relative reproductive success of an organism in passing genes to the next generation (Roeder, 1997). Multiple aspects of recombination have been studied, including its mechanisms of production and the role of recombination events in evolution (Hudson & Kaplan, 1985). In this study we examined how maternal age affects the rate of recombination. Our hypothesis states that recombination rate is positively correlated with maternal age. If this is true we would expect to see recombination rate, in progeny, increase as the parental …

Biophysical And Functional Characterization Of Rhesus Macaque Igg Subclasses, Austin W. Boesch, Nana Yaw Osei-Owusu, Andrew R. Crowley, Thach H. Chu, Ying Chan, Joshua Weiner, Pranay Bharadwaj, Rufus Hards, Mark Adamo, Scott Gerber, Sarah Cocklin, Joern Schmitz, Adam Miles, Joshua Eckman, Aaron J. Belli, Keith Reimann, Margaret E. Ackerman

Dartmouth Scholarship

Antibodies raised in Indian rhesus macaques [Macaca mulatta (MM)] in many preclinical vaccine studies are often evaluated in vitro for titer, antigen-recognition breadth, neu- tralization potency, and/or effector function, and in vivo for potential associations with protection. However, despite reliance on this key animal model in translation of promising candidate vaccines for evaluation in first in man studies, little is known about the proper- ties of MM immunoglobulin G (IgG) subclasses and how they may compare to human IgG subclasses. Here, we evaluate the binding of MM IgG1, IgG2, IgG3, and IgG4 to human Fc gamma receptors (FcγR) and their …

Self Hypnosis For School Success: Empowering Adolescents With Anxiety And Stress, Nilani Shankar

Doctoral Dissertations

Self-hypnosis is a treatment that has been utilized to address the social-emotional concerns of adolescents with high levels of anxiety and stress. In this study, a multiple baseline design across three high school-aged participants was implemented to examine whether self-hypnosis could decrease symptoms of anxiety and stress and help to improve health-related quality of life (HRQoL). The results of the study indicated that the treatment resulted in decreases in trait and state anxiety for two out of three participants, improvements in stress levels for two out of three participants, and improvements in HRQoL for all three participants. Participants reported that …

Career Morph: Quantitizing Adversity In Academic Medicine, Carol Isaac, Rebecca Mcsorley, Alexandra Schultz

The Qualitative Report

Many qualitative researchers reject textual conversion based on philosophical grounds although others believe it facilitates pattern recognition and meaning extraction. This article examined interview data from 52 physicians from a large academic medical center regarding work–life balance. Analysis ranked men and women in four career tracks: Clinician-Educator, Clinician-Researcher, Clinician-Practitioner, and residents. The purpose of this paper is to illustrate how a qualitatively driven (QUAL→quan) mixed method design illustrated differences between stratified groups. Although many initial codes were similar for men and women, their language was gendered and generational in context of work-life balance. Results indicated that women (and low-status men) …

Objectives: This work was conducted to create a predictive mathematical model for Salmonella spread, distribution and outbreak in local wastewater resources with understanding the mechanisms and impacts of seasonal environmental drivers.

Methods: Empirical models were developed to solve several biologically distinct mechanisms of Salmonella sp by which seasonality can impact their interactions, including seasonal changes in replication, distribution and mortality rates.

Results: Mathematical models and field observations show that the strength and mechanisms of seasonality can alter the spread and …

Does Depth And Sanitation Type Affect The Quality Of Faecal Sludge In The Tropics? The Case Of Yaoundé, Cameroon, W.A. Letah Nzouebet, I. M. Kengne, A. Rechenburg

Open Water Journal

Background: Faecal sludge (FS) management is a challenging problem in low-income countries where large parts of the urban population rely on onsite sanitation systems (Koné, 2010; Strande et al., 2014). In these countries, the discharge of raw faecal sludge directly into the environment is a common practice that threatens environmental and public health, because pollution of water resource. To avoid this situation, characterization of faecal sludge for adequate treatment before discharge into the environment is needed. Many studies were carried out on the faecal sludge characterization and treatment (Kengne, 2008; Bassan et al., 2013). Cameroon like other sub-Saharan countries lack …

Establishing Sediment Concentration Rating Curves In The Upper Blue Nile Basin, Mamaru A. Moges, Fasikaw A. Zemale, Muluken L. Alemu, Getaneh K. Ayele, Dessalegn C. Dagnew, Seifu A. Tilahun, Tammo S. Steenhuis

Open Water Journal

Because of scarcity of continuous sediment data for rivers, methods have been developed to predict sediment loads based on few discontinues measurements. Traditionally, loads are predicted using rating curves that relate sediment load to discharge. The relationship assumes inherently a unique relationship between concentration and discharge and therefore although performing satisfactorily in predicting loads, it may be less suitable for predicting concentration. This is especially true in the Blue Nile basin of Ethiopia where concentrations decrease for a given discharge with the progression of the rainy monsoon phase. The objective of this paper is to improve the sediment concentration predictions …

Ecological Status Of Hot Springs In Eastern Amhara Region: Macroinvertebrates Diversity, Sisay Derso, Adebe Beyene, Melaku Getachew, Argaw Ambelu

Open Water Journal

Springs are the places where ground water is discharged at specific locations. They vary dramatically as to the type of water they discharge. Hot springs are having the temperature of the water lies significantly above the mean of annual air temperature of that region. Temperature is one of the most important factors that govern species abundance and distribution. The objective of this study is to examine the relationship between biological parameters (macroinvertebrate diversity) with physicochemical water and habitat quality of hot springs in Easter Amhara Region. A cross-sectional study of physical, chemical and biological components of the hot springs were …

Economic Valuation On Participatory Gully Rehabilitation In The Ethiopian Highlands, Getaneh K. Ayele, Azalu A. Gessess, Meseret B. Addisie, Seifu A. Tilahun, Tigist Y. Tebebu, Daregot B. Tenessa, Eddy J. Langendoen, Charles F. Nicholson, Tammo S. Steenhuis

Open Water Journal

The current severity of gully erosion is a major cause of increased sediment loads in rivers, but gully rehabilitation has proven to be challenging, with limited success. This paper describes gully rehabilitation efforts in the Ene-Chilala in the Blue Nile basin begun in early 2013, where low-cost gully rehabilitation has been effective with community participation. Initially farmers were reluctant to participate for religious reasons but with the aid of local priests and respected elders, community discussions and a visit to a rehabilitated gully, a consensus was reached to rehabilitate a 0.71-ha upland gully. The gully cut the foot path of …

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-Wildlife Conflict In Selela Village, Nicole Chlebek, Laura Stalter

CrissCross

The beastly journey of long-distance migration for the African Elephant (Lexodonta Africana) is important for upholding their connections between diminishing protected areas, especially in northeastern Tanzania. However, human development is encroaching into these corridors, creating a human-elephant conflict, which can ruin livelihoods of villagers, depending on the extent of conflict. This study focused on exploring the hypothesized human-elephant conflict on the Selela corridor, specifically in Selela village, as well as GPS (Global Positioning System) mapping evidence of elephant travel along the projected Selela elephant corridor connecting Ngorongoro Conservation Area (NCA), to Selela Forest Reserve (SFR), and finally to …

Cultural Intelligence Sounding The Death Knell For Stereotypes In Business Communication, Eugene A. Ohu

Global Advances in Business Communication

Globalization is creating culturally diverse teams. Managers are increasingly challenged to lead multicultural teams towards common organizational goals. It has therefore become imperative that team members be helped to quickly attain a shared understanding of messages. Much research has focused on generating awareness of different cultures and how this knowledge can be used to improve business communication.

Even with this awareness that different cultures exist, stereotypes (of race, gender, national culture) still influence how team members interpret the actions of their colleagues. Studies in social psychology have focused on how stereotypes influence perceptions about individuals or groups of people. Message …

Characterizing The Function Of Amino Acid Transporter Acypi008971 In The Pea Aphid/Buchnera Symbiosis, Yu-Ching Hsu

Open Access Theses

Sap-feeding insect have associated with bacterial symbionts for hundreds of millions years. These symbioses have increased insect fitness, facilitating their persistence through evolutionary time. The symbionts of sap-feeding insects provide their hosts with amino acids that are found at very low concentrations in their diets. Typically amino acid metabolism is partitioned between host and symbiont so that the host synthesizes non-essential amino acids while the symbiont contributes essential amino acids. The biosynthesis of some amino acids however, requires enzymes encoded by both the host and the symbiont. Understanding how amino acid metabolism is integrated between insect host and bacterial symbiont …

Anthropogenic Disturbance Modulates Mammal Community Diversity, Assembly, & Abundance: Emerging Infectious Disease Risk In The Greater Yellowstone Ecosystem, Leticia Andrea Gutiérrez Jiménez

Dissertations

This dissertation examines the role of mammalian biodiversity in maintaining overall ecosystem health in the Greater Yellowstone Ecosystem (GYE). The study explores the pathways by which anthropogenic disturbance prevents or promotes the emergence of human infectious diseases. I studied two paramount research questions: Question 1: What are the direct effects of anthropogenic disturbance on rodent community assemblages and the consequent indirect effects on public health? I first surveyed the GYE rodent community and their pathogens by using land use as a measure of anthropogenic disturbance (e.g., human settlements, horseback ranches, pastures, undisturbed). I identified pathogens in rodent blood samples by …

Synthetic Ion Channels: A New Class Of Membrane Disruptor And Efflux Pump Inhibitor For The Recovery Of Antibiotic Potency, Mohit Bharatkumar Patel

Dissertations

Antibiotic resistance has become a world-wide health care crisis. In 2013 there were 50,000 deaths in U.S. and EU, associated with hospital acquired bacterial infections. This problem is exacerbated by the lack of new antibiotics in development. Here, we report that synthetic amphiphiles represent a new class of adjuvants that rescue antibiotic potency against multidrug resistant bacteria. Hydraphiles are amphiphiles, designed and synthesized in Gokel lab, that show many of the same properties as protein ion channels. Hydraphiles were previously shown to have antimicrobial activity against Escherichia coli, Bacillus subtilis and Saccharomyces cerevisiae. Here, we report that hydraphiles recover the …

Endogenous Small Interfering Rna: Insights Into Esirna Biogenesis And Their Precursors, Andrew White Harrington

Dissertations

Rarely in research is the path to an answer straightforward. Initial questions lead to more questions, many times doubling back to allow for greater insight into the original question. For example, discovery of interactions between previously unrelated pathways can lead to breakthroughs with regard to understanding of gene regulation. One such novel interaction and the subsequent discoveries this interaction spurred are discussed herein. Transposons, or “Jumping Genes” are mobile genetic elements found throughout all three major domains of life. Transposons comprise 44% of the human genome and possess the ability to move within the genome. This ability makes them an …

Color-Mediated Foraging By Pollinators: A Comparative Study Of Two Passionflower Butterflies At Lantana Camara, Gyanpriya Maharaj

Dissertations

Colorful floral signaling and resulting insect foraging behaviors have only been extensively examined in hymenopteran pollinators, especially bees, in comparison to flies, beetles, and butterflies regardless of their ecological importance. Therefore, my study provides novel information by focusing on foraging behaviors of adult passionflower butterflies, Heliconius melpomene and Dryas iulia, to the color changing flowers of Lantana camara. My dissertation which is divided into four chapters, aims to explore various aspects of color mediate foraging in passionflower butterflies by combining observations in the wild with controlled field and laboratory experiments. In the first chapter I reviewed flower color development and …

Sexual Orientation Microaggressions In High Schools, Marti Lee Baricevic

Dissertations

Sexual orientation-based discrimination in schools has evolved from primarily blatant, overt forms to include subtler and ambiguous forms. Recent research has found that same-gender-attracted youth are more resilient in managing school-based discrimination than previously reported. Within the framework of Symbolic Interactionism, this dissertation used a basic qualitative approach, influenced by Grounded Theory methods, to investigate sexual orientation microaggressions in high schools, strategies employed by same-gender-attracted students in managing sexual orientation microaggressions, and the relationship between microaggressive experiences and sexual identity. Fourteen adolescents, ranging from ages 16 to 19, from seven separate schools, who self-identified as lesbian, gay, bisexual, and queer, …

An Algorithm For Calculating The Inverse Jacobian Of Multirobot Systems In A Cluster Space Formulation, Christopher Jude Waight

Mechanical Engineering Master's Theses

Multirobot systems have characteristics such as high formation re-configurability that allow them to perform dynamic tasks that require real time formation control. These tasks include gradient sensing, object manipulation, and advanced field exploration. In such instances, the Cluster Space Control approach is attractive as it is both intuitive and allows for full degree of freedom control. Cluster Space Control achieves this by redefining a collection of robots as a single geometric entity called a cluster. To implement, it requires knowing the inverse Jacobian of the robotic system for use in the main control loop. Historically, the inverse Jacobian has been …

The NAABB consortium test beds produced over 1500 kg of biomass for downstream processing. The biomass production included a number of model production strains, but also took into production some of the more promising strains found through the prospecting efforts of the consortium. Cultivation efforts at large scale are intensive and …

Active Learning Tour Route: Engagement In An Unconventional Environment, Hattie Molina

Honors Projects

When guest attend Bowling Green State University for a campus visit, a majority of their experience is comprised of tour guides talking “at” them. The campus tour is made up of a lot of facts and stories provided by the tour guide, but few questions by guests or based on comments from guests. One way to solve this is to create an Active Learning Tour route where guest are the center of their own campus learning experience. According to the research, the components of Active Learning have many facets that branch into other aspects including technology and humor. The aim …

Building Better Water In Lake Erie, Morgan Potts
