Curio-Stereo: A VR Application for the Viewing of Stereograph Cards

This project discusses the historical significance of stereograph cards as a tool for constructing a shared visual culture in the late 19th and early 20th centuries in the United States and the United Kingdom. Stereographs were widely popularized as an entertainment and educational tool, offering an immersive experience for the viewers. The stereoscopic nature of the images allowed the viewers to immerse themselves in a non-physical reality through visual stimulation, creating a haptic involvement that was unique to the medium. The project of creating a VR application to view stereographs is presented as a potential solution to the problem of the paper media\u27s deterioration and current presentation. The VR application would offer a way for viewers to experience stereographic cards in an immersive, illusionary manner, providing an opportunity to connect early stereoscopic and immersive technologies with modern VR environments. This project provides a significant opportunity to advance digital collection access and create virtual galleries, studios, and art pieces, enabling users to appreciate the artistic and historical value of stereograph cards

Implementation of National Pediatric Guidelines to Prevent Chemotherapy Induced Nausea and Vomiting in Children with Cancer

Purpose: The purpose of this study was to assess the use of supplemental, as needed (prn) pharmacologic interventions for uncontrolled acute chemotherapy induced nausea and vomiting (CINV) in children with cancer after implementation of new pediatric CINV prophylaxis guidelines. Description of Project: A retrospective chart review was completed on forty-three children admitted to the hospital for chemotherapy during a 3 month period in 2017 to document the use of medications given for acute breakthrough CINV. The pre-implementation group received anti-emetics based on the institutional standard of care. A second retrospective chart review was completed on thirty-three children admitted to the hospital for chemotherapy during a 3 month period in 2018 to evaluate use of medications for acute breakthrough CINV. The post-implementation group received anti-emetics based on the new published pediatric guidelines. Patient characteristics, treatment information, and provider compliance with guidelines were collected. Results/Conclusions: Implementation of the guideline by the institution was successful with 91% of patients in the post-intervention group receiving the new anti-emetic regimen to prevent nausea and vomiting. The mean anti-emetic dose in all patients for breakthrough CINV pre-implementation was 4.837±10.4857. Post-implementation, the mean anti-emetic dose for all patients was 3.394±6.432. This was not statistically significant (p =0.462). For patients under 12, the mean anti-emetic dose pre-implementation was 5.8±12.5333 and post-implementation was 3.882±8.1. This was also not statistically significant (p =0.55). Data collected from this project did demonstrate a decrease in the number of breakthrough anti-emetics used in children under 12 years of age likely related to the addition of the drug aprepitant. Although clinical guidelines provide excellence guidance to clinicians, they must always be evaluated for risk versus benefit; adapted to individual patient circumstances as appropriate; and used within the context of expert clinician judgement

Sublethal toxicant effects on fish foraging behavior: A mechanistic approach

Previous studies of toxicant effects on fish foraging behavior have taken a strictly empirical approach which had little basis in ecological theory and did not allow development of a testable hypothesis a priori to field verification of laboratory results. A mechanistic approach was taken in this study to examine the sublethal effects of four copper concentrations (0, 25, 150, 1800 ug/l) on the foraging behavior of bluegill Lepomis macrochirus. Twelve separate laboratory experiments were conducted. Two experiments assessed copper effects on the reaction distance of bluegill to untreated zooplankton. Ten experiments were done to assess copper effects on the functional response of bluegill to untreated (5 tests) and treated (5 tests) invertebrate prey of different types. Copper had no effect on the reaction distance of fish to zooplankton. Copper reduced bluegill consumption rates of all untreated prey but not treated prey groups. Prey handling time for bluegill capturing treated and untreated prey increased significantly with copper concentration and was the most consistently sensitive parameter measured. Capture efficiency by bluegill was not as consistent a measure of toxicant stress. These experiments suggest that mechanistic measures are consistent indicators of toxicant effects on fish feeding behavior and that copper concentrations as low as the USEPA water quality criteria may alter food consumption and reduce growth of fish in the wild;Laboratory results were incorporated into an optimal foraging model to predict the diet breadth of treated and untreated fish in a lake. Bluegill in replicated, littoral-zone mesocosms were exposed to 1 of 3 copper concentrations (0, 36, 130 ug/l) for four days. The stomach contents of the fish were compared with ambient prey availability and the diet predicted by the optimal foraging model. The model did not provide a good estimate of diet breadth for fish in the mesocosms. Small differences in the energetic return rate between optimal and suboptimal diets, and errors in determining estimates of model parameters may account for discrepancies between the observed and predicted diet

Haptic Preservation of Cultural Ephemera: an Extended Reality Solution Using Stereoscopic Experience Replication for Victorian Parlor Culture

This study presents a solution to the problem of interacting with, while simultaneously preserving, fragile cultural heritage, such as Victorian parlor culture artifacts, which are essential cultural heritage items but at risk of damage and deterioration. The proposed multi-sensory experience uses extended reality (XR) technology, head-mounted displays (HMD) and haptic feedback via haptic gloves, providing an immersive experience that allows people to interact with these artifacts in a virtual environment. By replicating the experience of a Victorian parlor, this study provides a glimpse into the past and provides valuable resources for researchers. The proposed solution not only provides access to the public and researchers of a collection, but also addresses the conflicting demands of curators and conservators by preserving these artifacts while still engaging a modern audience. The approach mitigates incidents of further deterioration or vandalism, ensuring the long-term preservation of cultural heritage resources. Through XR technology, viewers can handle fragile examples of technology, such as stereoscopic images, stereocards, and stereographs, without risking damage to the original materials. Haptic feedback can simulate the texture of the objects, providing a more realistic and immersive experience. Moreover, this study highlights the importance of preserving cultural heritage leveraging emerging technologies and emphasizes the historical and cultural significance of these objects

Toxicity of dietary methylmercury to fish: Derivation of ecologically meaningful threshold concentrations

Threshold concentrations associated with adverse effects of dietary exposure to methylmercury (MeHg) were derived from published results of laboratory studies on a variety of fish species. Adverse effects related to mortality were uncommon, whereas adverse effects related to growth occurred only at dietary MeHg concentrations exceeding 2.5 µg g −1 wet weight. Adverse effects on behavior of fish had a wide range of effective dietary concentrations, but generally occurred above 0.5 µg g −1 wet weight. In contrast, effects on reproduction and other subclinical endpoints occurred at dietary concentrations that were much lower (<0.2 µg g −1 wet wt). Field studies generally lack information on dietary MeHg exposure, yet available data indicate that comparable adverse effects have been observed in wild fish in environments corresponding to high and low MeHg contamination of food webs and are in agreement with the threshold concentrations derived here from laboratory studies. These thresholds indicate that while differences in species sensitivity to MeHg exposure appear considerable, chronic dietary exposure to low concentrations of MeHg may have significant adverse effects on wild fish populations but remain little studied compared to concentrations in mammals or birds.

Development of a Nurse Anesthesia Program Point-of-Care Ultrasound Airway Examination Curriculum

Airway management is a critical and fundamental skill for anesthesia providers. Point-of-care ultrasound (POCUS) is an up-and-coming assessment technique that can provide critical information about a patient’s airway anatomy and may increase patient safety during anesthesia care. As a result, understanding the appropriate POCUS equipment, techniques, findings, and clinical implications for airway examination can become essential for safe and effective anesthesia practice. This project aimed to develop a clinical airway POCUS examination curriculum with detailed instructions on all aspects of appropriate examination equipment, set-up, technique, and implications for findings. The team designed the curriculum to incorporate it into the host Nurse Anesthesia program and to utilize it in future anesthesia coursework. It included an educational PowerPoint presentation with a voiceover lecture and a hands-on skills development lab conducted for third-year Nurse Anesthesia students at Southern Illinois University Edwardsville (SIUE). Pre-lab and post-lab surveys were collected to enable a comparative analysis of the curriculum\u27s effectiveness. The post-lab data showed that most students began with limited knowledge of the necessary elements of airway POCUS examination but ended the lab session with significantly increased confidence in their ability to perform an airway POCUS examination

Perspectives of College Students with Disabilities Regarding Their High School Transition Experience: Notes for High School Transition Planning

Students with disabilities face many challenges as they transition to postsecondary education. These students are often unprepared for the rigor of postsecondary academics; they often lack self-efficacy skills and have limited awareness of postsecondary supports or cannot successfully access them. This study aims to give voice to college students with disabilities to inform practices of high school personnel involved with transition and higher education professionals supporting them. Using Kohler’s Transition Taxonomy 2.0 (2016), researchers sought to study the perspectives of eleven college students on their high school transition experiences in the areas of academic preparedness, self-advocacy skills, and experiences with college counseling. Each of the eleven participants took part in individual interviews designed to inquire about each of the above areas of focus. This paper confirms the study participants felt they were primarily passive participants in their Individualized Education Plan and their postsecondary transition planning process during high school. They also relied heavily on family support during the transition to postsecondary education. Participants also felt unprepared for the academic rigor of college due to the heavy modifications and support given in high school classes and their inexperience with time management. Students also desired more information from their high school transition team, IEP team, and counselors about support available for students with disabilities in college. Recommendations for high school transition practices and future opportunities for research are discussed

Fish Associated with Dikes, Revetments, and Abandoned Channels in the Middle Missouri River

Fish associated with dikes, revetments, and abandoned channels along the Iowa-Nebraska portion of the Missouri River were collected by seining, electrofishing, and hoop netting in June, August, and October 1983. Samples collected by seining dike fields and abandoned channels were\u27 dominated by Cyprinidae and Centrarchidae. Electrofishing samples were dominated by flathead catfish (Pylodictus olivaris), gold eye (Hiodon alosoides), common carp (Cyprinus carpio), river carpsucker, (Carpiodes carpio), gizzard shad (Dorosoma cepedianum), and blue sucker (Cycleptus elongatus) in dike fields and revetted banks and by gizzard shad, river carpsucker, and bigmouth buffalo (lctiobus cyprinellus) in the abandoned channels. Among fish collected in unbaited hoop nets, blue suckers and channel catfish (lctalurus punctatus) were prevalent in dike fields; blue suckers, flathead catfish, and shortnose gar (Lepisosteus platostomus) along revetted banks; and white crappie (Pomoxis annualaris), black crappie (P. nigromaculatus), river carpsucker, black bullhead (lctalurus melas), bigmouth buffalo, and gizzard shad in abandoned channels. Gear selectivity and differences in sampling efficiency in the diverse riverine habitats precluded statistical comparisons of most samples and stressed the need for development of improved sampling techniques and designs for large river fishery research
