A pathway toward activating social equity in public administration education from the bottom up: The case of the energy and environmental justice educational and advocacy program
No full textThese are the slides from a presentation given at the 2025 NASPAA Global Conference held in Flagstaff, Arizona on 10/09/2025.Social equity is a core principle in public administration, yet its practical application has often lagged behind significant theoretical advancements. This article addresses that gap in doctoral education programs, exploring how bottom-up, student-led experiential learning (BUSLEL) can serve as a pathway to activate social equity (ASE) in public administration education. The Energy and Environmental Justice Educational and Advocacy Program (EEJEAP) exemplifies how such initiatives can complement traditional top-down methods and help bridge the gap between theory and practice. EEJEAP engages students in studying the administrative burdens faced by low-income households seeking energy assistance in Douglas County, Kansas. This program not only provides students with hands-on research opportunities and fosters personal and professional growth but also demonstrates the potential of BUSLEL models to enhance public administration curricula. EEJEAP makes a meaningful contribution to ASE efforts in public administration doctoral education by equipping students to navigate complex equity challenges
Compression Bond Lengths: Study of Test Data and Design Equations
No full textCompression development and lap-splice length provisions in ACI 318-19 §25.4.9 and §25.5.5 are reexamined after an example
was used to show that existing provisions can produce unexpected results in some design conditions, such as compression lap splices
longer than tension lap splices. A historical review of ACI Building Codes shows that existing compression bond length provisions are
largely based on provisions adopted before test data were available. The provisions in ACI 318-19 are compared with a database
of 89 test results and shown to poorly fit the data. Several compression and tension bond equations are also examined and found to
fit the data better. It is shown that compression development and lap-splice lengths can be based on several expressions available
in the literature for tension development length with minor modification, including the ACI 318-19 equation for tension development
length. Using this approach would simplify design by eliminating the use of different expressions to calculate tension and compression development lengths, prevent calculated lengths from being longer in compression than in tension, and provide a better fit to available data
The Sticky Side of Sugar, Spice, and Everything Nice: Quantifying the Binding of Li+ to Triphenylphosphine Oxide (TPPO) with 7Li and 31P NMR and Volatile and Particulate Emissions from Home 3D Printers
No full textThis undergraduate thesis was submitted to the Department of Chemistry in Partial Fulfillment of the Requirements for the Degree of
Bachelor of Science with Honors.The behavior of lithium cations in nonaqueous solvents influences the performance of lithium-ion batteries; however few measurements have systematically and quantitatively examined the properties of lithium salts in nonaqueous solvents. Results from nuclear magnetic resonance studies designed to interrogate the properties of lithium salt species in the nonaqueous solvents acetonitrile, propylene carbonate, and tetrahydrofuran are presented in the first chapter of this thesis. A suite of lithium-7 and phosphorus-31 spectral data have been collected to study the interactions of lithium cations with a model ligand, triphenylphosphine oxide (TPPO), by titration methods. Our results reveal that the Li-7 chemical shift is dependent on the concentration of added TPPO; however, the equilibria measured for binding of TPPO depend on the nucleus being interrogated, Li-7 or P-31 respectively, a phenomenon attributable to the titration conditions and ratio of reagents used in the titration studies interrogating each element. Ligand binding and solvent effects are discussed, including comparisons between the solution behaviors of various lithium salts. Taken together, current results suggest that both solvent and lithium counteranion identity impact the speciation in nonaqueous solvents. Additionally, the concentrations of lithium and TPPO (as well as the ratio of these concentrations) strongly influence the quantitative data resulting from individual titrations, underscoring the uniqueness of the individual measurements on closely related sets of solution conditions.
The rapid expansion of 3D printing technologies has led to increased utilization in various industries and has also become pervasive in the home environment. Although the benefits are well acknowledged, concerns have arisen regarding potential health and safety hazards associated with emissions of volatile organic compounds (VOCs) and particulates during the 3D printing process. The home environment is particularly hazardous given the lack of health and safety awareness of the typical home user. The study presented in the second chapter of this thesis aims to assess the safety aspects of 3D printing of PLA and ABS filaments by investigating emissions of VOCs and particulates, characterizing their chemical and physical profiles, and evaluating potential health risks. Gas chromatography–mass spectrometry (GC–MS) was employed to profile VOC emissions, while a particle analyzer (WIBS) was used to quantify and characterize particulate emissions. Our research highlights that 3D printing processes release a wide range of VOCs, including straight and branched alkanes, benzenes, and aldehydes. Emission profiles depend on filament type but also, importantly, the brand of filament. The size, shape, and fluorescent characteristics of particle emissions were characterized for PLA-based printing emissions and found to vary depending on the filament employed. This is the first 3D printing study employing WIBS for particulate characterization, and distinct sizes and shape profiles that differ from other ambient WIBS studies were observed. The findings emphasize the importance of implementing safety measures in all 3D printing environments, including the home, such as improved ventilation, thermoplastic material, and brand selection. Additionally, our research highlights the need for further regulatory guidelines to ensure the safe use of 3D printing technologies, particularly in the home setting
Hidden Hands: US Dependence on Indigenous Power in the Nineteenth-Century American Southwest
No full textThis is the paper from a presentation given at the Nordic Association of American Studies held in University of Turku, Finland on 06/04/2025.In the 1860s, the US Army relied heavily on its alliance with the Akimel O’odham in Arizona to realize its aspirations of defeating slavery in the South and wresting control of the West from Indigenous peoples. During this critical time, O’odham partnership aided the meager army force in establishing a Southwest military network while advancing the Tribe’s efforts to protect its homeland, people, resources, and autonomy from non-Native and Intertribal threats. Union-O’odham cooperation crushed Confederate dreams of a coast-to-coast empire, weakened the alliance’s Indigenous enemies, such as the Apache, and ultimately shaped the Southwest for conquest
A Feasibility Study for a Critter Crossing Under the South Lawrence Trafficway
No full textThis capstone was submitted in partial fulfillment of the requirements for EVRN 615, taught by Dr. Kelly Kindscher and Dr. Ali Brox.The construction of the South Lawrence Trafficway disturbed and divided the Haskell Wetlands, one of the most diverse habitats in Kansas, necessitating remediation efforts from Louisiana Street to O’Connell Road. This construction disrupted the movement of wetland species including small-mouthed salamanders and otters, leading to significant wildlife-vehicle collisions in the area. Interruptions of this scale have negative effects on populations and damage the integrity of the wetlands, leading to large-scale degradation. Wildlife corridors have been constructed across the United States to facilitate the movement of organisms above and below roads, and the construction of a semi-aquatic underpass below the trafficway has the potential to greatly decrease above ground crossings and collisions. Our feasibility study combines animal migration studies, geographical analysis, and engineering concepts to propose an ideal location for a semi-aquatic underpass along the trafficway. This passageway will be placed in an area that maximizes animal traffic while minimizing disruption to the trafficway in order to make construction more appealing to government stakeholders. The construction of these underpasses would reduce animal mortality rates and restore ecological connections between the divided halves of the Haskell Wetlands. Relevant stakeholders and possible sources of funding are included in the study since community mobilization and grants will be critical to the completion of this project. Thus, this feasibility study aims to provide a foundational plan for the approval and construction of an underpass for Baker University, Haskell Indian Nations University, and other interested groups
The political is the personal: political conflict within families in Brazil, 2018-2024
No full textThese are the slides from a presentation given at the 88th MSS Annual Meeting held in Chicago on 03/14/2025.The rise of contemporary right-wing movements has been followed by dramatic political conflicts in Brazil. Clashes within families are among the most severe. They display a surprisingly varied morphology, ranging from avoidance and rupture of social relations, well into open threats and violence. Their underlying motivations are not any less diverse, including economic interest, political loyalty, and libidinal aspects. This presentation elaborates on results from preliminary interviews on this subject, carried mostly in São Paulo, in preparation for my current research. Three conjectures are advanced and illustrated: (1) political strife within families can be understood in analogy to corresponding forms of intervention in the public arena; (2) conflict among kin is better understood as posing a new form of relatedness, not as dissolving existing social relations; (3) variations in the development of such conflicts (according to class, race, gender) are summarized in the functions kinship systems and household relations assume within different communities
