We the People. Who? The face of future American politics is shaped by perceived foreignness of candidates of color
Get PDFPursuing a more equitable political representation of a country\u27s demographics is essential both as a matter of principle and pragmatism (i.e., realpolitik). As such, the goal of the present study was to replicate and expand on research on the impact of voter race/ethnicity and ideology on voting behaviors and interpersonal judgments of political candidates of color from different racial and ethnic groups. After participants (N = 282) saw the same political candidate of color (randomly assigned to identify as Mexican American vs. African American), we assessed interpersonal judgments and behaviors (e.g., expertise, voting intentions), perceived Americanness, and memory for skin tone of the candidate. In support of hypotheses and previous research/theory, white voters expressed more positive interpersonal judgments toward the African American political candidate and rated him to be more American than the Mexican American political candidate. We expanded upon previous research by directly testing the role of perceived Americanness in the differential judgments of political candidates’ race/ethnicity by white voters, with evidence supporting partial mediation. Our findings further showed that judgments toward a political candidate of color were also predicted by voters’ political affiliation. Specifically, conservative (vs. liberal) voters generally expressed less positive interpersonal judgments toward the candidates of color and perceived them to be less American and patriotic. Ramifications related to these findings are discussed
The Impact of After-School Math Club on Elementary Student Math Anxiety
Get PDFMany students experience math anxiety, which can harm mathematics achievement. Taking part in fun, hands-on, inquiry-based math activities has been shown to decrease student anxiety. For four semesters, we ran an after-school mathematics club at Presbyterian Day School in Cleveland, MS for students in grades 3-5. The activities and materials were supplied by Crazy 8s Math Club (a Bedtime Math company). In this manuscript, we share three specific activities that encouraged both student engagement and problem-solving skills. Then we discuss survey results from the Crazy 8s Math Club as they relate to lower student math anxiety
RC Baja Project: Suspension and Steering
Get PDFStudents designed and manufactured an RC Baja car to compete in the ASME RC Baja competition. The goal of this section of the project was to create a steering system and suspension system that work together properly with a partner’s chassis/drive train systems during tests and competitions. The car needed to be able to complete in the three events, which are a drag race, a solemn course, and the Baja event. The RC will also be evaluated on the ability to climb inclines, top speed, and withstand the drop test. This proposal will explain all the details and effort that went into the design and manufacture process that made the steering and Suspension section of this project. Requirements were decided for both portions of this device to help determine what the RC car should look like and how it should operate to be successful in competition. Design used of statics, mechanical design, and dynamics. The design of these systems was accomplished using the 3D modeling program SolidWorks and calculations on green sheets. These two systems were manufactured by methods including machining, 3D printing, and buying parts. Machined parts were made using the Bridgeport but also the lathe and CNC mill. These processes have resulted in an RC car that is able to withstand and not bottom out from drop of 3’, the battery was able to operate for 30 minutes at a time without being charged, and was able to operate from a distance of 10ft away
NASA Student Launch - Payload
Get PDFA team of mechanical engineering, physics, and computer science students from Central Washington University have constructed a fully functional subscale model rocket to be flown at the NASA Student Launch competition. The rocket’s payload was designed to open the nose cone and take a photo of the rocket’s surroundings after descending from the launch. Smaller parts were constructed through machining and 3D printing that will be added to the purchased major component, the linear actuator, in order to perform the required tasks. These tasks are signaled by an attached electronics board, which will receive an RF command remotely, execute code, and commence the deployment sequence. The payload’s testing primarily concerns the 3D printed or constructed components’ strength, as well as the functionality of the electronic components within the payload. The electronic components must remain in place during the ascent/descent sequence, and the constructed parts must keep them secure. The payload’s final weight was approximately 4.0 pounds. The target altitude was 5,000 feet, and the test flight altitude was roughly 4,700 feet. During the test deployment, camera’s opening was 3 inches wide, and the camera rotated 360 degrees for the photo. Three structural plates held the payload together during the launch sequence, the descent/landing, and the deployment. The wiring stayed put, enabling the electronics to perform their tasks, with the linear actuator opening the nose cone 6.2 seconds after landing, and the camera taking a photo of the rocket’s surroundings. Final launch results are expected to effectively mirror those of testing
JCATI Carbon Fiber Recycler: Oven Heating System
Get PDFCentral Washington University Mechanical Engineering Technology students are working with the Joint Center for Aerospace Technology Innovation (JCATI) to create a device that recycles carbon fiber wing trimmings produced by the wing manufacturing process for the Boeing 777 airplanes. The solution to this problem was to utilize crushing, shredding, and pyrolysis to remove the resin from the composite material and provide carbon fiber that can be repurposed. This project focuses on both the Oven Enclosure which will house the Oven Heating System as well as the heating elements and control circuit that are responsible for allowing the material to reach pyrolyzation temperatures. Several engineering methods were utilized in order to achieve the desired outcomes. Firstly, an oven enclosure was constructed. This composed of sheet metal and mineral wool insulation which was able to keep the heat maintained within its environment. Next, the heating elements and purge gas components were assembled in the oven. Lastly, these sub-assemblies were incorporated into an electrical circuit that was easily accessible and able to initiate, control, and power down the system. After thorough design evaluation, construction, and proper testing, the shredded material was successful in reaching target temperatures for pyrolyzation and producing an output of 77% fully recycled carbon fiber within the 30-minute time limit

Floodplain Aquifer Storage Capacity in Upper Yakima River Tributaries, Kittitas County, WA
Get PDFLarge wood (LW) restoration projects were recently implemented in the Upper Yakima Basin following the destructive logging practices of the early 20th Century, which stripped Upper Yakima River tributaries of LW. The removal of natural LW increased incision, isolating channels from floodplain aquifers, and degrading resident and anadromous fish habitat. Returning streams to their natural state through instream LW installations is believed to increase floodplain groundwater storage by decreasing channel incision, increasing floodplain-channel connectivity, and raising the water table elevation. Additional storage in floodplain aquifers can help combat the adverse effects of climate change, namely decreasing snowpack and earlier melting. Storing infiltrating snowmelt and river water during peak flow in shallow floodplain aquifers could allow the natural release of groundwater as baseflow through the dry summer. Taneum Creek, Indian Creek, and Teanaway River have established LW projects and are candidates for floodplain aquifer storage. However, a regionally wide spread gray silt layer could affect potential aquifer transmissivity and storage capacity. Through fieldwork, mapping, and grain-size analysis, the groundwater storage volume was quantified taking into consideration the effects of the stratigraphy on groundwater storage, recharge, and flow. Volume estimates indicate a potential floodplain aquifer capacity of 1,040-1,990 acre-feet in the North Fork Teanaway watershed and 352-1,320 acre-feet in Taneum Creek
Impact of the Washington State COVID-19 Lockdown on 5-10-Year-Ol School-Aged Children Residing in Kitties County
Get PDFBackground: The Washington State COVID-19 lockdown and subsequent school closures brought increased dependency on parents to provide nutritious meals and opportunities for physical activity for their children.
Purpose: The aim of this study was to describe the impacts of the Washington State COVID-19 lockdown on the dietary, physical activity, and screen time habits of children ages 5-10-years-old residing in Kittitas County.
Methods: A researcher-developed Qualtrics survey was created and validated via the Index of Item Objective Congruence. The survey was administered to parents via Facebook, using local Kittitas County Facebook groups.
Results: Most parents identified that the Washington lockdown negatively impacted their children, with parents identifying that at least 73% (n = 57) of children consumed a SSB on any given day, 59% (n = 46) consumed breakfast once per week, 4% (3) met PA recommendations, and 30% (n = 24) exceeded screen time recommendations.
Conclusions: The impact of the Washington State COVID-19 lockdown on children is multifactorial and includes factors such as family income and the severity of COVID-19 lockdown policies. Kittitas County parents viewed the Washington State lockdown as having an overall negative impact on their children
Characterizing cellular injury and inflammation with ALDOB-/-Mouse model of MAFLD
No full textMetabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. Previous studies demonstrate that mice lacking the enzyme ketohexokinase, responsible for phosphorylating fructose to F1P, do not accumulate F1P and are resistant to developing MAFLD. However, common MAFLD animal models fed a fructose-rich diet take months to develop pathology. Alternatively, mice deficient in aldolase B, which cleaves F1P, will readily accumulate excess intracellular F1P and show exaggerated hepatic ballooning, macrovesicular lipid droplets, and immune cell infiltration. In this study, aldoB-/- mice, and their WT counterparts, were fed diets ranging from 0% to 0.71% fructose (w/w), for 1, 3, or 7 days, or until mice lost 20% of their initial bodyweight before fructose exposure. Histological analysis of liver tissue, quantification of total lipids, and evaluation of clinical markers of liver disease was used to characterize the development of steatosis, inflammation, and collagen deposition. We find that the aldoB-/- model develops symptoms of MAFLD without dietary fructose exposure, making it an appropriate MAFLD model. With introduction of dietary fructose, aldoB-/- mice develop more severe symptoms similar to non-alcoholic steatohepatitis (NASH), providing an inducible model for NASH. Because of this, the aldoB-/- model can aid in research about the transition between MAFLD and NASH, as well as help to identify biomarkers associated with both
Strength Under Pressure: Superwoman Schema (SWS) and Intimate Partner Violence (IPV) among Black Women
Get PDFIntimate Partner Violence (IPV) is a prominent public health issue in the U.S., and evidence suggests that IPV disproportionately affects Black women. Additionally, Black women who are victimized may be reluctant to report and/or seek supportive services. Given these disparities, it is important to understand the context of IPV in the Black community. Although the Superwoman Schema (SWS) conceptual framework’s utility for explaining other health-related outcomes, such as mental health issues, among Black women is emerging, its use to understand the experiences of Black women and IPV in the Black community is limited. In this paper, we provide an overview of the SWS and IPV to find intersectionality between the two among Black women, including risk factors for victimization, barriers to the usage of mental health services, strength used as a coping mechanism, religious and spiritual concerns and interventions needed for Black survivors. We argue that there is great need for more research using the SWS to understand IPV among Black women, how SWS must be integrated into cultural competency training for counselors, and policies that keep Black women who report IPV safe from incarceration
