Beyond the individual: Clinicians' perspectives on interventions for sexually based offenses through an ecological lens
No full textThesis (Ph.D.)-- Wichita State University, College of Liberal Arts and Sciences, Dept. of PsychologyThe current interventions used for the treatment of individuals convicted of sexual offenses focus primarily on individual risk and protective factors, with minimal incorporation of environmental and social factors. The purpose of the current study was to explore how, if at all, treatment providers incorporated non-individual level factors into the treatment of individuals convicted of a sexual offense, what benefits they perceived to this incorporation, and what barriers they perceived to further incorporation. Semi-structured interviews were conducted with fifteen (n = 15) providers across three midwestern states. Reflexive thematic analysis was used to analyze participant interviews for each research question, resulting in eight themes. Three themes were found related to how providers incorporate non-individual level risk and protective factors into treatment: (1) Addressing from the Inside-Out, (2) Preparing for Social Consequences, and (3) Supporting the Support Systems. Two themes were found related to the benefits providers perceived to the incorporation of non-individual level factors into treatment; (1) Treatment Buy-In, and (2) Pro-Social Growth. Finally, three themes were found related to the barriers providers perceived to further incorporation of non-individual level factors into treatment: (1) Enduring Social Contempt, (2) Institutional Apathy, and (3) What is Broken Cannot Expand. These findings suggest that despite ecological level barriers, providers are working to incorporate nonindividual level factors into their treatment approach, perceive a benefit to this incorporation, and are interested in the further incorporation of these factors into current treatment methods
Investigating the cryogenic gas storage capabilities of thermoplastic fiber reinforced composites incorporated with invar metal sheets
No full textThesis (M.S.)-- Wichita State University, College of Engineering, Dept. of Mechanical EngineeringThis research explores the development and characterization of a hybrid thermoplastic composite system composed of carbon fiber reinforced Polyaryletherketone (PAEK) prepreg with centrally embedded Invar 36 metal sheets. Designed for cryogenic fuel storage and aerospace applications, the hybrid aims to enhance dimensional stability, reduce thermal expansion, and improve impact resistance under extreme conditions. Fabrication was performed using a hot-press molding technique, supplemented by plasma surface treatment to improve interfacial adhesion between the carbon fibres and metal layers.
Mechanical and thermal characterization was conducted through three-point bending, cryogenic flatwise tensile testing, drop-weight impact, Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Thermomechanical Analysis (TMA), and surface analyses using SEM and Laser Confocal Microscopy (LCM). Water contact angle measurements were used to evaluate surface wettability improvements post plasma treatment.
Results showed that the hybrid composite withstood thermal degradation up to 853 K, with an earlier onset at 838 K surpassing the CFRP-only laminate. Flexural tests indicated improved peak load (1194.7 N) and energy absorption. Under cryogenic impact at −196 °C, the hybrid showed a faster, more ductile response, absorbing 2712 N at 1.60 ms. Critically, TMA data confirmed a measurable reduction in the coefficient of thermal expansion in the hybrid, validating its enhanced dimensional stability. SEM and LCM analysis revealed fewer microcracks and delamination in hybrid samples, supporting improved structural integrity.
In conclusion, the integration of Invar 36 sheets into a thermoplastic CFRP matrix demonstrably improves thermal endurance, dimensional precision, and damage tolerance, offering a robust material solution for next-generation cryogenic and aerospace applications
Development of analytical protocols for rapid and sensitive analysis of herbicide residues with flow-gated capillary electrophoresis
No full textThesis (Ph.D.)-- Wichita State University, College of Liberal Arts and Sciences, Dept. of of Chemistry and BiochemistryCapillary electrophoresis (CE) has become an important technique for the separation and detection of ionic species due to the advantages it carries, including high separation efficiency, reduced consumption of reagents and samples, and rapid analysis. However, preconcentration methods are often required in CE when it comes to detecting trace levels of analytes due to its low sample injection volume and short optical pathlength. The goal of my research projects was to develop efficient and robust preconcentration techniques for sensitive detection of herbicide residues in environmental and food samples via flow-gated CE. This dissertation first presents a simple and robust preconcentration technique: field-amplified sample injection (FASI) coupled with electrokinetic supercharging (EKS). It was successfully applied to the sensitive detection of herbicide residues in surface water systems with flow-gated CE, and it improved the detection sensitivity of glyphosate (GlyP) by 861 times with high accuracy and precision. Then, FASIEKS technique was studied comprehensively using various combinations of the electropherograms of FL and 5-FAM, fluorescence imaging, and computer simulations. As a result, two kinds of EKS processes were studied: two-step EKS and simultaneous EKS. The twostep EKS method was applied to the detection of GlyP residues in cereal samples. Lastly, the extraction efficiency of commercial molecularly imprinted polymer (MIP) cartridges for GlyP and aminomethylphosphonic acid (AMPA) was tested. GlyP and AMPA got 84% and 70% recovery, respectively. In addition, we found that the cartridge had excellent desalting ability: the conductivity of water samples from Arkansas river was reduced by 99.9% after the SPE via the MIP cartridge. The cartridge can be used for desalting where salts often generate adverse effects on the detection sensitivity and accuracy
Supernova pointing capabilities of DUNE
No full textThis is an open access article under the CC BY license.The determination of the direction of a stellar core collapse via its neutrino emission is crucial for the identification of the progenitor for a multimessenger follow-up. A highly effective method of reconstructing supernova directions within the Deep Underground Neutrino Experiment (DUNE) is introduced. The supernova neutrino pointing resolution is studied by simulating and reconstructing electron-neutrino charged-current absorption on (Formula presented) and elastic scattering of neutrinos on electrons. Procedures to reconstruct individual interactions, including a newly developed technique called “brems flipping,” as well as the burst direction from an ensemble of interactions are described. Performance of the burst direction reconstruction is evaluated for supernovae happening at a distance of 10 kpc for a specific supernova burst flux model. The pointing resolution is found to be 3.4 degrees at 68% coverage for a perfect interaction-channel classification and a fiducial mass of 40 kton, and 6.6 degrees for a 10 kton fiducial mass respectively. Assuming a 4% rate of charged-current interactions being misidentified as elastic scattering, DUNE’s burst pointing resolution is found to be 4.3 degrees (8.7 degrees) at 68% coverage. © 2025 Published by the American Physical Society.Fundação para a Ciência e a Tecnologia, FCT; National Science Foundation, NSF; Institut National de Physique Nucléaire et de Physique des Particules, IN2P3; Science and Technology Facilities Council, STFC; H2020 Marie Skłodowska-Curie Actions, MSCA; Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro, FAPERJ; Ministerio de Ciencia e Innovación, MICINN; South Korea; Spine Education and Research Institute, SERI; HORIZON EUROPE Framework Programme; Centre National de la Recherche Scientifique, CNRS; Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TUBITAK; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq; NRF; European Commission, EC; U.S. Department of Energy, ENERGYGOV; Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP; Fundação de Amparo à Pesquisa do Estado de Goiás, FAPEG; Natural Sciences and Engineering Research Council of Canada, NSERC; Fermilab, FNAL; Xunta de Galicia; CEA; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNSF; NextGenerationEU, NGEU; Royal Society; European Regional Development Fund, EFRE; Generalitat Valenciana, GVA; CERN, CERN; Ministerstvo Školství, Mládeže a Tělovýchovy, MEYS; Istituto Nazionale di Fisica Nucleare, INFN; UK Research and Innovation, UKRI; Fermi Forward Discovery Group, LLC, (89243024CSC000002); Office of Science, SC, (DE-AC02-05CH11231); Office of Science, SCThe ProtoDUNE-XX detector was constructed and operated on the CERN Neutrino Platform.

Temperature and dung availability drive intraspecific dung beetle body size across grassland grazing regimes
No full textClick on the DOI link to access this article at the publishers website (may not be free).Animal body size is an important trait with implications for an organism's ecological roles. Larger dung beetles can bury more dung, increasing soil nitrogen retention, reducing greenhouse gas emissions, and reducing livestock parasites. We studied two focal dung beetle species across shortgrass prairie sites to examine the influence of four key drivers (local temperature, plant nutrient availability, presence and density of large mammalian grazers and insecticide use) on intraspecific beetle body size and trap catch.
Dung beetles were collected using pitfall traps for one growing season. We collected over 17,000 dung beetles and measured body size parameters on over 4600 individuals of two common species in northeastern Montana, USA: Canthon pilularius, a large native species, and Onthophagus nuchicornis, a smaller non-native species, across 24 field sites. Bayesian linear models were used to estimate body sizes and trap catches, and to assess responses to grazing regimes and habitat characteristics.
The lowest trap catches for both species were in sites treated with insecticides and ungrazed sites. Compared with other treatments, C. pilularius was most numerous in sites grazed by cattle, and O. nuchicornis was most numerous in untreated prairie dog sites. C. pilularius tended to have smaller body sizes in sites with insecticide use and bison and cattle units, but was larger in areas with more browser dung (deer [Odocoileus spp.] and pronghorn antelope [Antilocapra americana]). O. nuchicornis had smaller body sizes in prairie dog sites. Hotter temperatures within the 20?days prior to capture resulted in smaller individuals, especially of the native species C. pilularius, while increased browser dung 20?days prior to capture was associated with larger body sizes in both beetle species.
Dung beetle species varied in their responses to large herbivores and dung availability, with browser dung being a potentially overlooked key resource for the most common, native dung roller in our system. Lag effects had measurable impacts on dung beetle body size, suggesting environmental conditions during dung beetle development can affect the ecosystem services dung beetles provide. Warming temperatures due to climate change may reduce body sizes of dung beetles, negatively affecting their ability to provide ecosystem services related to animal waste removal and nutrient cycling
Why people who believe in God fear death
No full textPeople who report believing in God fear death. They also experience grief when someone they love dies. Philosophers and social scientists sometimes claim that this can only be plausibly explained by the hypothesis that people who claim to believe in God do not really believe in God. I show that this is mistaken. I identify three independently plausible explanations of why people who genuinely believe in God would have these behaviors and attitudes. First, there is an evolutionary explanation of why the fear of death would be resilient even if one genuinely believes God has good things in store for us after death. Second, people often fear low probability outcomes. It may be that religious people are afraid of hell or the cessation of existence even if they judge those outcomes to have a low probability. Third, belief in God is typically combined with views according to which death is accompanied by the permanent loss and radical transformation of important relationships
Demographic change in high-income East Asian economies—Implications for human resource management
No full textThis is an open access article under the CC BY license.The industrialized high-income economies of East Asia—Japan, South Korea, and Taiwan—are some of the most rapidly aging in the world. We examine the changing demographics of these economies and analyze how organizations can best manage the transition to a workforce that is rapidly aging and beginning to shrink. We synthesize from different sources an overview of the aging situation, explain how it affects businesses, and provide cases of organizations that have implemented human resource policies to make their workplaces more inclusive and supportive of older employees. Government efforts to promote active aging, family-friendly regulations, higher birth rates, and create more open immigration policies to attract talent are also briefly discussed. We point out some steps that organizations can take to better integrate older workers and provide insights for managers and policy makers to deal with emerging issues. © 2025 Wiley Periodicals LLC
Electric aircraft: Infrastructure challenges for airports
No full textPublished in SOAR: Shocker Open Access Repository by the Wichita State University Libraries Technical Services, October 2025.Aviation as an industry has committed to 2050 as the target date for carbon neutrality. This requires a shift to alternative fuels, with electric aircraft being one of the options, with several examples in the certification pipeline. As technology has trended towards energy efficiency, airports have not had an impetus to focus on increasing energy distribution capacity, and therefore, they will not have the infrastructure to support electric aircraft. This will be particularly true for smaller, general aviation airports. This paper draws on experiences with an electric aircraft to provide a snapshot of what it takes to interface with the airport grid, electrical infrastructure requirements for charging, charging inefficiencies, and other limitations. The findings can be scaled up to suggest broader requirements to meet the needs of widespread deployment of electric aircraft. Airport master plans should include provisions for expanding the electrical grid capacity and ideally implementing solar projects as a sustainable solution
