Field-Curing Methods for Evaluating the Strength of Concrete Test Specimens
Get PDFThe purpose of this combined laboratory and field study was to evaluate field-curing methods of concrete specimens for estimating the early opening strength of an in-place concrete item. One Illinois Department of Transportation (IDOT) class PV mix was used to cast cylinders, beams, and in-place concrete slabs in October 2021 and February 2022. Concrete cylinders were cured using three methods: ambient air (method #C1), an insulated box/cooler (method #C2), and a power-operated box (method #C3). Beams were cured using two methods: ambient air (method #B1) and an insulated plywood box (method #B2). The cast-in-place specimens from each slab and cylinder were tested for compressive strength, and beams were tested for flexural strength after 1, 3, and 7 days of curing. One cylinder and one beam in each curing method along with slabs were embedded with sensors to collect temperature variation with time. Only methods #C1, #C2, and #B1 were selected for evaluating further in the field, and data were collected from the IDOT District 5 box culvert demonstration project. Laboratory results showed that the insulated box (method #C2) estimated early (1–3 days) and ambient air (method #C1) estimated the 7-day compressive strength of an in-place concrete item within an acceptable range. Field results showed that method #C2 cylinders mimic the in-pour temperature better than method #C1 cylinders. Further statistical analyses supported the results observed in the laboratory and field
Perceived Ostracism and Fathers’ Experiences of Grief and Trauma After Miscarriage
Get PDFMiscarriage can be a traumatic experience with serious mental health implications for parents. However, fathers’ experiences and outcomes post-miscarriage are understudied compared to those of mothers. Previous research focused on mothers’ experiences found that perceived ostracism correlated with grief intensity and posttraumatic stress symptoms, predicting unique variance in symptoms beyond grief intensity factors. We replicate several of these research findings in a sample of fathers and demonstrate that their perceived ostracism correlated positively with posttraumatic stress symptoms and negatively with grief reality (i.e. the pregnancy did not feel real to them). Perceived ostracism also explained additional variance in posttraumatic stress symptoms when considered alongside grief intensity measures that typically predict traumatic symptoms

Using a Pharmacokinetic Model to Design and Evaluate an Early ctDNA Biomarker for Response to Targeted Therapy
Get PDFEarly prediction of response to therapy or lack thereof can help physicians plan treatment more efficiently. Biomarkers based on circulating tumor DNA (ctDNA) are promising. However, biomarkers beyond direct comparison to baseline have not been thoroughly explored. We develop a model for ctDNA shedding under targeted therapy that incorporates pharmacokinetics. Using a simulated cohort of virtual patients with varied parameters, we define and analyze a biomarker based on ctDNA samples at baseline, 12 hours, and 24 hours after initiation of treatment. The biomarker identified patients who would achieve partial or complete response with high sensitivity and specificity and was able to match the performance of a neural network classifier. Our result highlights the potential of ctDNA as a biomarker and underlines the importance of early ctDNA data collection
Redbird Buzz Episode 51: Associate Director of Bands Dr. Mack Wood, January 24, 2025
No full textDr. Mack Wood, Illinois State University\u27s associate director of bands and director of the Big Red Marching Machine, joins Redbird Buzz for a behind-the-scenes look at all things marching band. The Big Red Marching Machine is comprised of more than 400 students representing every college on campus and is set to perform in Dublin, Ireland, at the 2025 St. Patrick\u27s Day Parade.
From discovering his passion for music at a young age, to serving as the University of Texas at Austin\u27s Longhorn Band drum major, to his current role leading the Big Red Marching Machine, Wood\u27s career in bands spans almost every level. He shares stories from his high school and college band director days, his experience at the Rose Bowl with the Longhorns, and how the Big Red Marching Machine\u27s stellar reputation ultimately brought him to Illinois State.
Tune into this episode to get a peek behind the curtain at the preparation and effort the directors and students in the Big Red Marching Machine put into a full season of football performances, how Wood has transitioned marching band processes to digital formats, and to hear about the importance of the band\u27s strong alumni base
Of Mice and Mutations
No full textMice have been a model organism in biological studies for hundreds of years from behavioral studies to vaccine research. My research uses North American deer mice (Peromyscus maniculatus) in their natural environment to investigate how genetic mutation frequencies change in populations of varying sizes. To analyze mutation frequencies, we capture deer mice on different islands in British Columbia’s Gulf Islands. The islands we sample from are of different sizes, which serves as a proxy for population size. We trap the mice at night using Sherman live-traps. Once a mouse is found in a trap, we scruff it and then take a small tissue sample from its ear before letting it go back into the night. This image shows how the mouse is scruffed before an ear tissue sample is taken.https://ir.library.illinoisstate.edu/ior2025/1008/thumbnail.jp
Reproductive futurity: Policy, Pop-Culture, and Praxis
Get PDFLike the depiction of plagues in apocalyptic science fiction, neoliberalism continues to infect education at all levels. This infection causes educators to care not for the children, but to embrace the figure of the Child. Reproductive futurism, in the imagined redemptive figure of the Child has been regulating the structure of education not for children, but for the exclusionary and decontextualized Child. This takes the shape of draconian accountability measures present in recent educational policies that do not have the best interests of children in mind, but rather the perceived redemption of society and culture, taking agency away from all within the field of education, to give it to educational policymakers
Addressing the Theory-Practice Gap Using Case-Based Learning and Imagined Roles in the Graduate Communication Disorders Classroom
Get PDFThe American Speech-Language-Hearing Association (ASHA) Code of Ethics (2023) requires all practitioners to uphold the welfare of others without discrimination. Graduate programs in communication sciences and disorders, therefore, must guide future clinicians to apply theoretical knowledge to clinical practice equitably and inclusively. This grounded theory study investigated how an instructor in a graduate communication sciences and disorders (CSD) class used case-based learning (CBL) to fill the theory-practice gap and guide students to think equitably and inclusively for future complex cases. Audio recordings from 12 hours of instructor-student discourse during one semester were transcribed and analyzed verbatim. Three interrelated, interactional themes emerged: the class structure, use of imagined roles (imagining how a clinician or parent/caregiver may respond), and use of equitable and inclusive language. Results highlighted how the instructor’s use of CBL was one effective method to scaffold learning and help fill the theory-practice gap and promote students\u27 co-construction of new knowledge. We propose that utilizing this three-fold approach was an effective way to help fill the theory-practice gap in an equitable and inclusive manner to further student learning without the need to overhaul the curriculum
Collaborative Counseling: Using Course-Embedded Experiences to Train Skills and Foster Confidence
Get PDFPracticing speech-language pathologists and graduate students identify a need for counseling training but feel unprepared to implement counseling in everyday practice. Within speech-language pathology, there is a dearth of evidence about best teaching practices for counseling. The current investigation examines the collaborative counseling program, which involves hands-on training with authentic clients with communication disorders. Thirty-six students across two cohorts participated in this study. Students composed individual reflections after each collaborative counseling session. Each cohort also participated in oral debriefings after each session. Reflections and debriefing transcripts were analyzed qualitatively through open and axial coding via micro and macro analyses. Micro analysis of individual reflections resulted in six overarching domains, 12 themes and numerous subthemes. Macro analysis of group and individual reflections resulted in three overarching themes: the learner’s state of being, client’s state of being, and skill development. Students gained confidence and efficacy in the ability to implement counseling and motivational interviewing techniques in authentic counseling interactions. They learned the value of exploring client values, perspectives, and how to capture this through notes that scaffold their ability to implement person-centered techniques. They also learned numerous counseling techniques and skills that they strengthened through repeated practice opportunities and feedback
Phonological Awareness Abilities of Undergraduate College Students: A Comparison of Students in Related and Unrelated Majors
Get PDFAn observational study was conducted to evaluate the differences in the phonological awareness (PA) abilities of undergraduate college students in majors related versus unrelated to PA. In order to participate, students must not have had any formal PA or phonetics instruction at the college level. A total of 116 undergraduate students voluntarily participated in an PA assessment, with results analyzed based upon the following three categories: Communication Sciences and Disorders (CSD) major, education major, and other major. Using non-parametric statistical analysis, there were statistically significant differences in CSD majors, in multiple categories of PA skills, compared to both education majors and other majors prior to any instruction in PA or phonetics.
