Neural And Behavioral Evolution In An Eavesdropper With A Rapidly Evolving Host, Aaron W. Wikle

Electronic Theses and Dissertations

The diversification of animal communication systems is driven by many interacting factors. Unintended receivers play an important part in this process, yet little is known about their role in signal evolution. Flies of the genus Ormia are parasitoids of crickets and rely on acoustic cues to locate hosts. In Hawaii, selection imposed by Ormia ochracea has led to recent and rapid diversification in the songs of their host. Here, we compare neural and behavioral responses of Hawaiian flies to those of an ancestral population to understand the role of parasitoid sensory and behavioral variation in the evolution of host songs. …

Surviving The Serenade: How Conflicting Natural And Sexual Selection Drove Rapid Diversification Of Mating Signals In An Insect, James H. Gallagher

Electronic Theses and Dissertations

Understanding how the early stages of sexual signal diversification proceed is of critical importance because the nature of these microevolutionary dynamics can directly shape species trajectories and macroevolutionary patterns. Unfortunately, studying signal diversification is challenging because signals involve complex interactions between behavioral, morphological, and physiological components, many of which can only be measured in real time. Here we had the opportunity to directly study this process with the recent increase in sexual signal variation in Hawaiian populations of the Pacific field cricket (Teleogryllus oceanicus). In Hawaii, male song attracts both female crickets and a deadly acoustically orienting parasitoid …

Quantification Of Nuclear Dynamics During Epithelial Remodeling, Noah De Leeuw

Electronic Theses and Dissertations

The morphogenesis of developing tissues is contingent on an extensive array of rearrangements in cellular shape, position and identity at large and small scales. One commonly used process to reshape tissues is the cell intercalation-driven elongation of a tissue in a common axis, in which rows of epithelial cells undergo oriented intercalation in a directional fashion. In most models of intercalation, cells are treated as homogeneous objects directed in their shape changes by cortical forces localized along cell-cell interfaces or tricellular junctions. However, less attention has been paid to how inhomogeneities in mechanical resistance of their own internal structures affects …

A Phenomenological Study Of Science Teachers’ Lived Experience: Pedagogical Judgment During The Covid-19 Pandemic, Amy Vo

Electronic Theses and Dissertations

At the beginning of the COVID-19 pandemic, in March of 2020, education in the United States changed dramatically. Science teachers began to look at the implementation of ambitious and equitable science teaching practices differently. Employing the hermeneutic phenomenological framework, the purpose of this study was to investigate the lived experience of science teachers, specifically looking at their pedagogical judgment related to ambitious and equitable science teaching. Semi-structured interviews, artifacts and surveys were used to develop a rich description of the phenomenon. Data analysis of the science teachers’ narratives, Qualtrics surveys, and lesson plans illuminated six essential themes common to all …

Mechanistic Insights Into Mftr-Dependent Regulation Of The Redox Cofactor Mycofactocin, Aigera Mendauletova

Electronic Theses and Dissertations

Organic redox cofactors are essential for life. While classic flavins and nicotinamides are widely distributed across all domains of life, nature has also evolved niche cofactors in subsets of life domains. For example, in Actinobacteria, coenzyme F420 is commonly used in place of flavin mononucleotide in enzymes associated with carbon fixation and oxidation of secondary alcohols. The importance of niche cofactors has long been recognized however, detailed understanding about their biosynthesis and physiological uses has been lagging. One class of niche cofactors is derived from ribosomally synthesized and posttranslationally modified peptides (RiPPs). To achieve their mature form, the genetically …

Artificial Emotional Intelligence In Socially Assistive Robots, Hojjat Abdollahi

Electronic Theses and Dissertations

Artificial Emotional Intelligence (AEI) bridges the gap between humans and machines by demonstrating empathy and affection towards each other. This is achieved by evaluating the emotional state of human users, adapting the machine’s behavior to them, and hence giving an appropriate response to those emotions. AEI is part of a larger field of studies called Affective Computing. Affective computing is the integration of artificial intelligence, psychology, robotics, biometrics, and many more fields of study. The main component in AEI and affective computing is emotion, and how we can utilize emotion to create a more natural and productive relationship between humans …

A Study Of The Cultural And Geological Environment Of The Magic Mountain Site In Golden, Colorado, Brianna K. Dalessandro

Electronic Theses and Dissertations

The Magic Mountain site, located in Golden, Colorado, has been the subject of intensive academic studies since the 1950s because of its extensive artifact assemblage and long habitation periods. The aim of this thesis was to use ground-penetrating radar, magnetometry, GIS models, and lithic analysis to further study when and how the Magic Mountain site was used during prehistoric times and contextualize a variety of hypotheses about site habitation and migratory patterns of prehistoric people in Colorado.

The results of these analyses indicate the habitation and migratory pattern of the Magic Mountain site was a periodic, but consistent, proximal visitation …

Chastity And Celibacy: A Rhetorical History Of A Rhetoric Of Sex And The Priest In The Catholic Church, Teresa Morales

Iowa Journal of Communication

The seemingly never-ending instances of reported sex abuse by Roman Catholic priests is commonly thought to be a matter of deviancy and crime. This is true; but there is more to the story. The RC Church has, for two thousand years, known of the sexual behaviors and deviancies of its priests, yet has accomplished little in controlling the situation. The rise of the lawsuit against the Church has led, finally, to the need to examine more deeply the reasons for this ongoing criminal behavior. This paper uses a method of rhetorical history to uncover and understand how and why this …

The Varieties Of Afterlife Experience: Epistemological And Cultural Implications, Everton De Oliveira Maraldi

International Journal of Transpersonal Studies

When parapsychologists talk about survival, they are usually implying personal survival, that is, a process in which memories, motivations, and personality characteristics of a given person somehow persist after bodily death. Are there other conceptions of survival (and of personal identity) that deserve further scientific examination? My purpose with this brief commentary is to expand on Rock et al’s approach by urging survivalists to discuss and investigate further the many different conceptions of (and explanations for) survival. I propose we critically reflect on our theoretical assumptions and their epistemological and cultural consequences.

Psi-Entific Approach To Post-Mortem Survival: Employing The Multiple Sources Of Psi (Msop) And Discarnate Psi Hypotheses In The Calculation Of A Drake-S Equation, Serge Merlin

International Journal of Transpersonal Studies

The continued investigations of the paranormal facilitated the development of novel theories and methodologies. Psi functioning of the living and the deceased in survival phenomena suggested the living agent psi (LAP) and discarnate psi hypotheses, but neither has demonstrated sufficient explanatory power to claim superiority in explaining survival data. Mediumship studies cannot determine whether paranormal information is sourced by means of discarnate psi or LAP, presenting the source-of-psi problem. Anomalous information can be obtained from joint sources (LAP, survival, or some other source), which supports the multiple sources of psi (MSoP) hypothesis. The maximized explanatory potential of the MSoP hypothesis …

Family Communication Patterns And Educational Orientations, Nathan Miczo, Lisa A. Miczo

Iowa Journal of Communication

This research investigates the impact of family communication patterns on educational orientations. Two hundred and nine students completed an online survey assessing family communication patterns (conversation and conformity orientation) and educational orientations (learning orientation and grade orientation). Regression analyses revealed that both conversation and conformity orientation were positive predictors of learning orientation, while only conformity orientation was a positive predictor of grade orientation. The discussion highlights the need for continued research into the role of the family as an influence on college student motivations.

Temperature Dependency Of Ion Channel Opennings, Loren Haarsma, Sebastian Grabill, Dylan Mount

Summer Research

Alamethicin is a 20 amino-acid peptide produced by fungus. When added to a lipid bilayer they self-assemble into voltage-dependent ion channels which open for brief periods called dwell times, usually on order of a few milliseconds. See poster by Dylan Mount regarding electrical properties of lipid bilayers without Ion channels. Our goal is to measure the electrical current through a single Alamethicin ion channel as it opens and closes and see how its gating behavior is affected by lipid temperature and lipid composition. Since lipid bilayers and ion channels are critical for almost all living cells, studying them can prove …

What About Tornadoes Makes Cars Fly?, Fred Haan, Minji Lee

Summer Research

Tornadoes move and evolve throughout their lifetime, causing several types of forces against objects. Although vehicles are observed to fly in real tornadoes, simulating this experimentally and numerically has been very difficult – the vehicles do not seem to want to fly. We studied the effect of pressure gradient forces. These have typically been ignored in past simulations, so we estimated them to see if they add the missing force to get things to fly. Some researchers have made mathematical models of tornado wind fields, so we used those models to estimate pressure gradient forces. We also used some full-scale …

A Critical Role For Staphylococcal Nitric Oxide Synthase In Controlling Flavohemoglobin Toxicity, Ryan M. Singh, Sujata S. Chaudhari, Sasmita Panda, Elizabeth H. Hutfless, Cortney E. Heim, Dhananjay Shinde, Abdulelah A. Alqarzaee, Margaret F. Sladek, Vineet Kumar, Matthew C. Zimmerman, Paul D. Fey, Tammy Kielian, Vinai Chittezham Thomas

Journal Articles: Cellular & Integrative Physiology

Most coagulase-negative staphylococcal species, including the opportunistic pathogen Staphylococcus epidermidis, struggle to maintain redox homeostasis and grow under nitrosative stress. Under these conditions, growth can only resume once nitric oxide (NO) is detoxified by the flavohemoglobin Hmp. Paradoxically, S. epidermidis produces endogenous NO through its genetically encoded nitric oxide synthase (seNOS) and heavily relies on its activity for growth. In this study, we investigate the basis of the growth advantage attributed to seNOS activity. Our findings reveal that seNOS supports growth by countering Hmp toxicity. S. epidermidis relies on Hmp activity for its survival in the host under NO stress. …

Small-Scale Sustainable Agriculture As A Platform For Experiential Learning, Devin Berg

ASEE North Midwest Section Annual Conference 2023 Publications

Background: Market pressures and the impacts of climate change are threatening the livelihoods of small-holding farmers around the world. As farmers themselves face shortages of workers and the pressures of climate change, adaptation is often required for sustainability. Solutions must be developed in collaboration with local communities to be sustainable, accessible, and equitable.
Method: These challenges provide opportunities for experiential learning within the engineering classroom. In this paper, I describe a diverse set of projects with a sustainable agriculture theme that I have used to enhance student learning through projects implemented in courses, capstone experiences, summer research programs, and independent …

Introduction To The Special Issue On Immunology, Colby Tofel-Grehl, Brooke A. Whitworth

Publications

The COVID-19 pandemic laid bare the absence of needed resources for teachers to engage students in learning about infectious disease as both a socioscientific issue and a scientific phenomenon (Kafai et al. 2022). With infectious disease largely absent from the NGSS, teachers had to creatively link lessons that contextualized and examined key aspects of infectious disease education during the COVID-19 pandemic. We saw in real time the impacts of popular news, social media, and public mood on broader socioscientific behaviors such as vaccination, masking, and social distancing. We watched as people’s understanding of the nature of science (Lederman 2013) …
