This high risk is often exacerbated by the burden of carrying a heavy self-contained breathing apparatus (SCBA). This study aims to explore the impact of SCBA weight on firefighters' musculoskeletal joint movements. Six firefighters participated in this study, performing four simulated firefighting tasks under three different SCBA weight conditions. A hybrid inverse kinematics approach was employed to analyze the kinematic data from two participants. The results revealed a notable decrease in lumbar range of motion (ROM) as the weight increased, particularly noticeable during hose advancement and stair climbing tasks. Conversely, an increase in hip ROM during stair climbing was observed, suggesting a compensatory response to reduced spinal flexibility. These findings underscore the critical need to understand the implications of turnout gear and SCBA weight to enhance firefighter performance and reduce the risk of injury.","PeriodicalId":520077,"journal":{"name":"Applied Human Factors and Ergonomics Conference","volume":"131 ","pages":"142-149"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11451450/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For diversifying faculty, Bennet et al. identified a barrier to be the lack of programs to support underrepresented groups at the postdoctoral and early career stages. The Pre-Professor Program (PREPP) was designed to support advanced doctoral students' and postdoctoral scholars' transition to faculty positions by engaging them in a semester-long virtual program within the California State University (CSU) system, which consists of 23 campuses across the state of California. PREPP Fellows receive individual mentorship from an experienced PREPP Mentor who engages them during weekly meetings to explore 15 topics and a few dozen activities related to teaching, service, and research at comprehensive and ethnically diverse institutions, as well as the process for applying for tenure track positions at such institutions. PREPP Mentors also discuss tenure and promotion processes and coordinate various campus and departmental activities to introduce PREPP Fellows to campus resources and learn perspectives of faculty life within their discipline. Initially designed as a local, in-person program, PREPP morphed into an online, virtual training program that allowed the program to grow and be implemented throughout the entire CSU system. The flexibility provided by the virtual platform enabled PREPP participants to be effectively immersed in learning about faculty life at a CSU campus without requiring them to be in the local area. This paper describes PREPP and how it can be used as a model to provide a pathway for highly competitive and diverse applicants to faculty positions.","PeriodicalId":520077,"journal":{"name":"Applied Human Factors and Ergonomics Conference","volume":"159 ","pages":"1871-1881"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11840917/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work established a 3D human thermal simulation to explore the thermal protection improvements of firefighters' turnout gear by using PCM segments under flashover and hazardous conditions. This simulation study will guide future experimental design and testing effectively and save time and effort. The study found that the 3.0-mm-thick PCM segments with a melting temperature of 60°C could extend the thermal protection time for skin surface to reach second-degree burn injury (60°C) by one to three times under flashover conditions compared to the turnout gear without PCM. Moreover, thinner PCM segments, i.e., 1.0-3.0 mm thickness, could also significantly mitigate the skin surface temperature increase while avoiding the added weight on the turnout gear. The 3D modelling results can be used to develop a next-generation firefighter turnout gear technology.","PeriodicalId":520077,"journal":{"name":"Applied Human Factors and Ergonomics Conference","volume":"131 ","pages":"133-141"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11451440/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142383360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For broad impact, research infusion can be implemented through careful redesign of courses or through the adoption of research modules to supplement class instruction and existing student training programs. In this paper, we present data on a program for the design and implementation of research-infused curricula in major courses across a variety of STEM and related disciplines. Specifically, the Research Across the Curriculum program's goal was to have faculty engage in a redesign of a class to exemplify how specific disciplines engage in research. Fourteen courses were included in the present analysis, and the redesigned components were implemented in the form of interactive activities for in-person or online learning. Overall, the redesigned courses had a large impact on student's perceptions of gains in research skills. Students reported moderate to good gains in understanding the relevance of research in their discipline and skills important to research like problem solving, understanding research papers, and interpreting research results. The modality of the course (online vs. face-to-face) had little impact. Thus, research-focused activities intentionally embedded in courses strengthen the research foundation of students and should be encouraged as a high-impact practice.","PeriodicalId":520077,"journal":{"name":"Applied Human Factors and Ergonomics Conference","volume":"159 ","pages":"1860-1870"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11845255/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate the perceived prevalence and impact of cognitive biases among cardiac surgery teams, and how these biases may affect intraoperative decisions and patient safety and outcomes. A mixed-methods approach was utilized, combining quantitative ratings across 32 different cognitive biases (0 to 100 visual analogue scale), regarding their \"likelihood of occurring\" and \"potential for patient harm\" during the intraoperative phase of cardiac surgery. Based on these ratings, we collected qualitative insights on the most-rated cognitive biases from semi-structured interviews with surgeons, anaesthesiologists, and perfusionists who work in a cardiac operating room. A total of 16 participants, including cardiac surgery researchers and clinicians, took part in the study. We found a significant presence of cognitive biases, particularly confirmation bias and overconfidence, which influenced decision-making processes and had the potential for patient harm. Of 32 cognitive biases, 6 were rated above the 75th percentile for both criteria (potential for patient harm, likelihood of occurring). Our preliminary findings provide a first step toward a deeper understanding of the complex cognitive mechanisms that underlie clinical reasoning and decision-making in the operating room. Future studies should further explore this topic, especially the relationship between the occurrence of intraoperative cognitive biases and postoperative surgical outcomes. Additionally, the impact of metacognition strategies (e.g. debiasing training) on reducing the impact of cognitive bias and improving intraoperative performance should also be investigated.","PeriodicalId":520077,"journal":{"name":"Applied Human Factors and Ergonomics Conference","volume":"130 ","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11342855/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142057941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
