What kind of bird is this? She will stop a galloping horse: an autoethnographic exploration of transnationality, motherhood, work, and education
No full textDoctor of PhilosophyDepartment of Educational LeadershipSusan M. Yelich BinieckiAdult learners who are also parents are often faced with balancing several responsibilities. Many are juggling family, academics, and work. The purpose of this study is to describe my lived experiences while navigating and negotiating transnationality, motherhood, work, and education identities. By applying the social, intersectional, non-linear conceptual framework of identity development (Cerulo, 1997; Crenshaw, 1989; Hoare, 2006; Josselson; Keller & Werchan, 2006; Tajfel & Turner, 1986; Yelich Biniecki & Conceição, 2014) as a researcher, I explore my lived experiences of transnationality and becoming a mother while pursuing a doctoral degree and working full-time through the lens of feminist autoethnography (Ettorre, 2016). In addition, I also incorporate interactions with family, friends, coworkers, other students and faculty, and the world. My experience is a unique example. My aim is to share a slice of personal reality and contribute to the bigger understanding of cultural experience that may impact other students as well. The findings of this study have the potential to greatly benefit the field of adult education by providing valuable insights on how institutions can effectively attract, retain, and support students throughout their academic journeys
Supplementary videos associated with “An electropenetrography waveform library for the study of probing and ingestion behaviors in Culex tarsalis”
No full textElectropenetrography (EPG) is a technique used to indirectly visualize and quantify unseen mouthpart movements that occur inside opaque host tissues when an insect or arthropod bites (i.e., probes). To use this technique on a specific insect, the electrical signals (called waveforms) generated during probing must first be characterized and correlated with insect behaviors. To this end, we characterized the waveforms generated by Culex tarsalis mosquitoes feeding on human hands and made video recordings of the insects during EPG. The findings from this investigation are published as “An electropenetrograpy waveform library for the study of probing and ingestion behaviors in Culex tarsalis.” This manuscript references supplementary videos containing highlights from the video recordings to show specific behaviors that occur during each waveform, which are archived here
Goals of Project Shop Well
Full text linkHello! My name is Rhianna Thomas and I am the founder of Project Shop Well, which is aimed at helping Americans start regularly buying from sources that truly promote human dignity. Because our market is saturated with companies who outsource their employment to sweatshops across the globe, there is a long way to go before we will be able to freely buy goods without worrying about where they were made. But a good way to start encouraging businesses to employ more ethical practices is to quit buying from the ones that do not. One of the first things that we can do is stop buying goods made in China
PipeDoll: A Motion Capture Addon for the Godot Game Engine
Full text linkCharacter animation is a key challenge in game development and other fields and is often created using motion capture. However, traditional motion capture requires specialized hardware and can be inaccessible for small teams. For this project, I have developed a 2D motion capture addon for the Godot game engine. The addon uses a machine learning model to perform motion capture using a standard webcam, avoiding the need for hardware. It meets all the key functional requirements identified for the project and is published as open-source software at https://github.com/ectucker1/pipedoll
Iron Dynamics Shape Host-Pathogen Interactions
Full text linkHosts and their pathogens often compete for trace metal elements that are essential to each of their survival. Iron is one of these trace metal elements and consequently, iron dynamics are central in host-pathogen interactions. Here we review how competition for iron during infection influences host-pathogen interactions and shapes disease outcomes. Hosts have developed diverse mechanisms to limit nutrient availability to the pathogen, also known as nutritional immunity. In response to infection, vertebrate, invertebrate, and plant hosts generate a hypoferremic environment using a variety of iron-binding proteins and chelators, alongside iron transporters, to limit pathogen replication. To counter nutritional immunity responses, pathogens use TonB-dependent (e.g., siderophores) and TonB-independent mechanisms to scavenge ferric and ferrous iron. Pathogens also compete with the host-associated microbiota to access iron. Competition between microbes for iron can either hinder or facilitate pathogen establishment and proliferation within hosts. Iron dynamics are an exciting new avenue for therapeutic interventions that may be employed against a broad range of pathogens
Phosphorus Fluxes in a Restored Carolina Bay Wetland Following Eight Years of Restoration
No full textRestoring wetlands on agricultural land can release soil phosphorus (P) to surface waters. Phosphorus is a limiting nutrient in many freshwater systems, thus restricting its release will improve surface water quality by preventing algal blooms. A P balance was used to examine how P was cycling in a Carolina Bay wetland eight years after restoration from prior-drained agricultural land. The change in soil P was evaluated between archived samples taken at restoration (2005), and eight years after restoration (2013). Measured P fluxes included atmospheric deposition, plant uptake, and loss to surface water outflow. The soil total P pool at the time of restoration was 810 kg P ha-1. No significant (α=0.05) decrease in the soil P pool was observed over the eight years. Atmospheric deposition contributed 1.0 kg P ha-1 yr-1, plants incorporated 3.3 P ha-1 yr-1 into woody biomass and 0.4 kg P ha-1 yr-1 as forest floor litter, and 0.2 kg P ha-1 yr-1 was lost to surface waters draining the wetland. Because the loss of P to surface waters was small, and because runoff water concentrations of P declined through this period of study to concentrations below those likely to cause eutrophication (< 0.1 mg L-1), we concluded that the wetland was not contributing to the degradation of surface water quality of nearby streams following restoration. Further, isolated wetlands such as that studied may be promising sites for future wetland mitigation projects due to limited impacts on surface water quality
Effects of a Selective D⁴ Antagonist on Repetitive Behaviors in a Genetic Model of ADHD in Rats
Full text linkBethany Plakke AndersonThis study aimed to investigate the efficacy of the selective D4 antagonist, A-412997, on repetitive behaviors of a rodent model of ADHD. We hypothesized that the drug would have no significant effect on repetitive behavior compared to the control groups. This would indicate that the D4 antagonist is comparable to and more effective than other treatments of ADHD, such as methylphenidate. Our study found significant strain effects for all three behaviors (digging, inactivity, and marble interaction) between the Long Evens control group and the spontaneously hypertensive rat (SHR) experiment group. We found that there were no significant impacts of drug exposure on marble interaction time and bouts, time spent inactive, bouts inactive, or digging time. Overall, this indicated that A-412997 could be an effective treatment for ADHD when looking at the possible side effects. Future directions should investigate other possible repetitive behaviors, in order to be sure that there is no confounding behavior that is impacted by this drug
Network-Based Regularization for Generalized Linear Models
Full text linkNetwork-based regularization has achieved success in variable selection for high-dimensional biological data due to its ability to incorporate correlations among genomic features. This package provides procedures of network-based variable selection for generalized linear models (Ren et al. (2017) and Ren et al.(2019) ). Continuous, binary, and survival response are supported. Robust network-based methods are available for continuous and survival responses
