Designing HMI and SCADA Laboratory Work for Engineering Students
Get PDFHuman-machine interfaces are, essentially, the user interfaces used to monitor industrial facility machines and systems, which makes them a common industry tool in engineering. At East Tennessee State University, while human-machine interfaces are briefly covered in lecture and graduate students have set up some basic hands-on work, there exist no formal lab work for students on the topic. This thesis explores the literature surrounding the design of labs for a STEM or engineering-specific university class, and applies the recommendations and methods within that literature to design two laboratory guides on human-machine interfaces. These labs are intended to be implemented in either (or both) the ENTC 3350 Industrial Electronics class or the ENTC 4517/5517 Automation & Robotics class at East Tennessee State University. This work also details the collection of student feedback and the refinement of the labs according to those results. It also notes roadblocks to the creation of a lab on the topic of supervisory control and data acquisition systems. Finally, this thesis provides several future recommendations for adjustments to the class materials, future labs, and education on supervisory control and data acquistion systems
Investigating the Lived Experiences of Graduate Students at the University of New Mexico
Get PDFResearchers at the University of New Mexico used a modified critical incident technique study to explore the lived experiences of graduate students in their roles as students, researchers, and teachers. The authors interviewed 20 graduate students in 2022 and then evaluated transcribed responses through two stages of qualitative coding. The students described their multiple roles during their graduate programs and the support they seek for their academic success and overall lives, along with common themes of struggling to secure adequate resources, both financial and social. Analysis of their responses will help align practitioner strategies and library service offerings with their needs, focusing on three major efforts: shaping a newly opened Graduate Commons into a nexus on campus; using existing library services, such as communications, marketing, outreach, and information literacy instruction, to improve the relationship between graduate students and the library; and creating more opportunities for graduate students to work within campus libraries. This study adds to the literature by representing a diverse urban student population in the southwestern United States, along with providing a snapshot of the short-term impact of the Covid-19 pandemic on graduate education
Learning To Be Trauma-Informed: An Examination of Individual-Level Factors Predicting Perceptions of and Response to Trauma-Informed Practice Trainings
Get PDFTrauma is a substantial threat to public health. As such, significant effort has been exerted into developing interventions which mitigate the consequences of trauma. Trauma-informed practice (TIP) aims to alleviate the effects of trauma by building policies and practices focused on safety, trust, transparency, support, collaboration, and empowerment. This study investigated how individual-level factors, including readiness for organizational change, perceived benefit of TIP training, and personal trauma history affect one’s ability to apply a TIP lens in a sample (n =100) of members of a graduate-level college. Further, it explored if one’s perceptions of and response to trauma-informed practice training predict changes in well-being, stress, and burnout. Results indicated that perceived benefit and readiness for organizational change are important predictors of post-training outcomes. Participants with a history of trauma performed more poorly on post-training trauma-informed knowledge questions. Results provided initial utility for use of objective measurement of trauma-informed application abilities
2025 April - Tennessee Monthly Climate Report
No full textHi All,
April was a very active weather month across Tennessee! Consequently, this is one of our longer monthly reports. The main weather and climate stories for April 2025 were the deadly severe weather, extreme rainfall and associated flooding, and record-setting heat that all occurred in the first week of the month. A series of weather systems set up across the central U.S. in the first week of April, with warm, moist air funneled into Tennessee from the Gulf. This pattern produced severe thunderstorms, heavy rainfall, and high temperatures from April 2nd to 6th. The series of storms began on April 2 with the NOAA Storm Prediction Center issuing a rare High-Risk alert (Risk level 5 of 5) that covered parts of West Tennessee. Rounds of severe storms began to impact the state in the afternoon and through the overnight hours into the morning of April 3. A total of 8 tornadoes impacted Tennessee from the afternoon of April 2 to the morning of April 3, with 2 EF-3 tornados, 2 EF-2 tornadoes, 3 EF-1 tornadoes, and 1 EF-0 tornado, and numerous reports of severe thunderstorm wind damage and severe hail (with a diameter or 1-inch or larger). Unfortunately, the storms on April 2-3 proved deadly with 9 reported fatalities and 20 injuries connected to the storms. Fayette, Hardeman, and McNairy counties were the hardest hit, with the EF-3 tornadoes both occurring after midnight in the early morning hours of April 3. Over the course of April 2-6 almost all of West Tennessee and northwestern portions of Middle Tennessee had rainfall that exceeded a 50-year storm (1/50 chance of exceedance in any given year). Some areas along I-40 from Memphis to Jackson, around Waverly in Humphreys County, and counties along the northwestern border with Kentucky exceeded rainfall totals for a 200-1,000-year storm, meaning there is a 1/200 to 1/1,000 chance of this much rain falling over a 4-day period in any given year. From April 2 to 7 the National Weather Service Office in Memphis issued a total of 223 warnings (96 tornado warnings, 82 severe thunderstorm warnings, and 45 flash flood warnings), which was only 29 fewer than the total number of warnings the office issued in all of 2024! As the storm systems shifted eastward on April 7, some heavy rainfall occurred in the mountains of East Tennessee. The strong southerly winds brought high temperatures to these parts of the state. Temperatures from April 1 to 7 ranged from 9°F to 17°F above normal for the week in southern Middle Tennessee and East Tennessee. Across the state from April 1-7 there were 37 daily record high temperatures set and another 23 tied daily high temperature records. There were also 70 broken and 9 tied daily records for warmest low temperatures set in the first week of April, all of these records were in Middle or East Tennessee. Check out the attached report for additional info, including maps and photos.

The Intersection of Appalachian Identity and Gambling Behavior
No full textThis study examined the relation between Appalachian identity and gambling behavior among students in central Appalachia (n = 395). One-way ANOVAs revealed no significant differences in engagement, F(2, 392) = 0.65, p = .523, or severity, F(2, 392) = 0.33, p = .718, across identification groups. Moderated regression showed that identity did not significantly moderate the engagement–severity relation (B = 0.073, p = .099), though engagement itself was a strong predictor of harm (B = 0.696, p \u3c .001, R² = .521). Negative affect predicted both engagement (B = 0.074, p = .001) and severity (B = 0.069, p = .001), while identity remained non-significant. Logistic regression found that identity predicted gambling engagement (Exp(B) = 1.18, p = .034) only when controlling for severity. These findings relay the importance of empirical efforts in Appalachia and suggest that Appalachian identity may not be an independent risk factor in gambling behavior
Strategic Enhancement of Biofuel Production Using Bacillus subtilis as a Model Organism: A Dual Approach of Gene Essentiality Mapping and Optimization
No full textWith rising global demand for renewable energy, enhancing microbial platforms for biofuel production is vital. This study engineered Bacillus subtilis to improve resilience to solvent stress by targeting membrane lipid biosynthesis pathways essential for integrity. Growth curve analysis (OD₆₀₀) showed that phosphatidylserine (PS) and phosphatidylethanolamine (PE) knockout strains grew significantly slower than wild type (168), indicating the importance of these lipids under stress. Laurdan fluorescence spectroscopy was used to assess membrane properties. Generalized polarization (GP) analysis revealed a concentration-dependent reduction in membrane order upon 1%–2% 1-butanol exposure. GP values declined progressively from control to 2% treatment, reflecting increased membrane fluidity and disruption. These results highlight membrane destabilization by biofuels and the protective role of specific lipids. Findings inform rational design of stress-tolerant microbial chassis. Future work will refine genetic constructs to restore lipid homeostasis and expand GP analyses to additional knockouts, supporting industrial-scale B. subtilis biofuel production
