Fatigue And Recovery In Pilots And Air Traffic Controllers: A Military Case Study, Pedro Piedade

International Symposium on Aviation Psychology - 2023

Fatigue is a known threat to individuals, especially in high demanding and risky tasks, because of its physical, mental, and emotional consequences. In high reliability organizations (HRO), fatigue is a hazard to safety management systems and requires effective mitigation strategies. At the individual level, recovery experiences enable the ability to manage stressful situations at work but can also be effective in dealing with fatigue. In this research, 137 military pilots and air traffic controllers from the Portuguese Air Force (PoAF) responded to an online survey. The results showed that both samples were especially impacted by mental fatigue, but air traffic …


Can You Hear Me? Simultaneous Masking Between The Stars Air Traffic Control Alarms, Corey Hall, Elliot Biltekoff, Matthew L. Bolton May 2023

Can You Hear Me? Simultaneous Masking Between The Stars Air Traffic Control Alarms, Corey Hall, Elliot Biltekoff, Matthew L. Bolton

International Symposium on Aviation Psychology - 2023

The Standard Terminal Automation Replacement System (STARS) was introduced to eliminate unnecessary Air Traffic Control (ATC) alarms and reduce air traffic controller confusion about alarms. The six STARS alarms are tonal melodies. Because of this, they are susceptible to simultaneous masking: where a tone cannot be heard in the presence of other sounds due to limitations of the human sensory system. This work used a proof-based computational method to analyze the STARS alarms to determine if any masking is possible. Our results found three instances where alarms could be partially masked (have part of their signal made inaudible) by other …

Applying Human-Centered Design To Ai-Enabled Pilot Scheduling, Amy L. Alexander, Audrey Haque, Michael Snyder, Rachael Kusiak, Brice Okubo, Kathie Chung, Eric Robinson

International Symposium on Aviation Psychology - 2023

Air Force mission and training scheduling is an immensely complex, time-consuming, and significantly manual process. A scheduling tool known as Puckboard has been developed to help C-17 squadrons transition from moving pucks across large whiteboards to utilizing technology to dynamically plan and deconflict resources in the presence of complex constraints. The overarching goal of incorporating artificial intelligence (AI) into this tool is to empower schedulers to quickly produce more efficient schedules that promote unit readiness, with more pilots completing their training syllabi faster, and with fewer disruptions to missions, training, and aircrew personal life. Our AI efforts focused on refining …

Development And Validation Of A Virtual Uam, Stacey M. Ahuja, Thomas Z. Strybel, Kim-Phuong L. Vu, Panadda Marayong, Praveen Shankar, Vernol Battiste

International Symposium on Aviation Psychology - 2023

Urban Air Mobility (UAM) refers to a system of passenger and cargo air-transportation vehicles within an urban area that is currently being designed to reduce demands for surface transportation. Their success depends on whether many obstacles to UAM operations are overcome. An important challenge to UAM success is the inability of the current air traffic management system to manage urban airspace, and new procedures and operating concepts are needed for coordination of UAM vehicles with existing commercial airspace traffic. Moreover, all systems currently under development initially will require remote or onboard pilots, and these pilots will need significant training to …

International Symposium on Aviation Psychology - 2023

Weather continues to play a significant role in general aviation (GA) events. GA pilots use various technologies to access and view weather information in the cockpit. These technologies range from handheld devices to installed displays. A contributing factor in many weather-related events was the pilots' failure to correctly interpret the displayed weather information compared to what was observed out the window. This session will highlight ongoing Human Factors (HF) research aimed at understanding and addressing this problem. Topics include an overview of the FAA’s Weather Technology in the Cockpit (WTIC) program; barriers to automating and implementing a speech-to-coded Pilot Report …

Learning About Routine Successful Pilot Techniques Using A Cued Retrospective Think-Aloud Task, Jon Holbrook, Chad Stephens, Lawrence J. Prinzel Iii, Sepehr Bastami, Daniel Kiggins

International Symposium on Aviation Psychology - 2023

Self-report can be a valuable method for collecting data about people’s goals and perceived motivations – data about aspects of crew thinking that are not otherwise readily observable. One of the challenges associated with collecting self-report data on routine successful performance, however, is that details may go unreported, be deemed unimportant, or may not be recalled. We report a study in which commercial airline flight crews participated in a video-cued retrospective think aloud after flying a high-fidelity simulated arrival into Charlotte airport. One day after flying the simulated arrival, crews were shown a video recording of their flight. The video …

On The Appropriate Participant Expertise For Display Evaluation Studies, M. M. Van Paassen, Clark Borst, Max Mulder, Gijs De Rooij, Ferdinand Dijkstra, Adam Balint Tisza

International Symposium on Aviation Psychology - 2023

Expert participants may not always be available for evaluation of new displays or support systems, and in some cases, it might be better to use novice participants, particularly when the display or support significantly changes existing work practices. To provide tools and arguments for selecting the expertise level of participants, we propose the use of Rasmussen’s decision ladder to analyze where and how a new visualization or a support tool changes the task, and identify steps where a novice participant may learn to perform the task to an acceptable level. A comparison to the support with the current operational interfaces …

A Competency Framework For Aviation Psychologists And Human Factors Specialists In Aviation, Sonja Biede, Federic Detaille, Optihum, Tina Narotra, Katarina Petrovic, Hermann Rathje, Alessandra Rea, Michaela Schwarz, Anna Vereker

International Symposium on Aviation Psychology - 2023

The new Commission Regulation (EU) 2018/1042 on technical requirements and administrative procedures includes psychological assessment of flight crew which refers to accredited Aviation Psychologists (AVPSY). However, the associated acceptable meansof compliance and guidance material does not provide a specific definition or requirements of such psychologists. Likewise, the term Aviation Human Factors Specialist (AVHFS) has not yet been legally recognised in Europe. AVHFS lacks a European definition and no pan-European competency-based endorsement exists. This paper reports the development of a competency framework by members of the European Association for Aviation Psychology (EAAP) and intendeduse in accreditation for AVPSY and AVHFS. It …


Effects Of Pubertal Growth Variation On Knee Mechanics During Walking In Female And Male Adolescents, Andrew W. Froehle, Brian A. Edwards, Matthew Peterson, Brian Meyerson, Dana Duren May 2023

Effects Of Pubertal Growth Variation On Knee Mechanics During Walking In Female And Male Adolescents, Andrew W. Froehle, Brian A. Edwards, Matthew Peterson, Brian Meyerson, Dana Duren

School of Health and Exercise Sciences Faculty Publications

Introduction: Puberty substantially alters the body's mechanical properties, neuromuscular control, and sex differences therein, likely contributing to increased, sex-biased knee injury risk during adolescence. Female adolescents have higher risk for knee injuries than male adolescents of similar age engaging in similar physical activities, and much research has investigated sex differences in mechanical risk factors. However, few studies address the considerable variation in pubertal growth (timing, pace), knee mechanics, and injury susceptibility within sexes, or the impact of such growth variation on mechanical injury risk.

Objectives: The present study tested for effects of variation in pubertal growth on established mechanical …

While corn is considered to be a healthy food option, common agricultural practices, such as the application of soil amendments, might be introducing contaminants of concern (COC) into corn plants. The use of dredged material, which contain contaminants such as heavy metals, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), as a soil amendment is increasing. Contaminants from these amendments can accumulate in corn kernels harvested from plants grown on these sediments and potentially biomagnify in organisms that consume them. The extent to which secondary exposure to such contaminants in corn affect the mammalian central nervous system has been virtually …

Measuring Claim-Evidence-Reasoning Using Scenario-Based Assessments Grounded In Real-World Issues, William L. Romine, Amy Lannin, Ankita Agarwal, Maha Kareem, Emily Burwell

Biological Sciences Faculty Publications

Improving students’ use of argumentation is front and center in the increasing emphasis on scientific practice in K-12 Science and STEM programs. We explore the construct validity of scenario-based assessments of claim-evidence-reasoning (CER) and the structure of the CER construct with respect to a learning progression framework. We also seek to understand how middle school students progress. Establishing the purpose of an argument is a competency that a majority of middle school students meet, whereas quantitative reasoning is the most difficult, and the Rasch model indicates that the competencies form a unidimensional hierarchy of skills. We also find no evidence …

Dredged Sediments Contain Potentially Beneficial Microorganisms For Agriculture And Little Harmful Cyanobacteria, Megan A. Rúa, Ashley N. Julian, Louise Stevenson

Biological Sciences Faculty Publications

Abstract Introduction Soils worldwide are degrading, raising concerns about our ability to feed the growing global population. Soil amendments that can alleviate degradation are gaining attention. The application of sediments dredged from waterways to agricultural fields has increasing promise as a means for improving degraded soils. However, herbaceous plant species may have difficulty establishing on dredged material because of low nutrient availability, inhibitory levels of toxins, unsuitable moisture conditions and lack of microorganisms capable of ameliorating these characteristics. To counteract these issues, we sought to understand if the use of a cover crop would increase the abundance, diversity and function …

Getting To The Root Of Tree Soil Microbiome Sampling, Sarah Addison, Megan A. Rua, Simeon Smaill, Kaitlyn Daley, Brajesh Singh, Steve Wakelin

Biological Sciences Faculty Publications

Microbiomes play critical roles in host functioning and therefore there is increasing interest in the microbiome assembly of plants. However, sampling strategies for long-lived perennial trees need to be standardised to produce robust data that accurately represents the microbiome over time. This issue is currently unresolved because there is little evidence indicating which portion of perennial tree species (e.g., root region or surrounding soil) is the best to sample to produce the most accurate measure of microbiome communities. Our aim was to sample different compartments of a plant’s belowground microbiome to identify the optimal sampling strategy to account for the …

Massive Loss Of Proprioceptive Ia Synapses In Rat Spinal Motoneurons After Nerve Crush Injuries In The Postnatal Period, Ariadna Arbat-Plana, Sara Bolívar, Xavier Navarro, Esther Udina, Francisco J. Alvarez Feb 2023

Massive Loss Of Proprioceptive Ia Synapses In Rat Spinal Motoneurons After Nerve Crush Injuries In The Postnatal Period, Ariadna Arbat-Plana, Sara Bolívar, Xavier Navarro, Esther Udina, Francisco J. Alvarez

Neuroscience, Cell Biology & Physiology Faculty Publications

Peripheral nerve injuries (PNIs) induce the retraction from the ventral horn of the synaptic collaterals of Ia afferents injured in the nerve, effectively removing Ia synapses from α-motoneurons. The loss of Ia input impairs functional recovery and could explain, in part, better recovery after PNIs with better Ia synaptic preservation. Synaptic losses correlate with injury severity, speed, and efficiency of muscle reinnervation and requires ventral microglia activation. It is unknown whether this plasticity is age dependent. In neonates, axotomized motoneurons and sensory neurons undergo apoptosis, but after postnatal day 10 most survive. The goal of this study was to analyze …

Long-Term Exposure To An Invasive Fungal Pathogen Decreases Eptesicus Fuscus Body Mass With Increasing Latitude, Molly C. Simonis, Lynn K. Hartzler, Gregory G. Turner, Michael R. Scafini, Joseph S. Johnson, Megan A. Rúa

Biological Sciences Faculty Publications

Abstract Invasive pathogens threaten wildlife health and biodiversity. Physiological responses of species highly susceptible to pathogen infections following invasion are well described. However, the responses of less susceptible species (relative to highly susceptible species) are not well known. Latitudinal gradients, which can influence body condition via Bergmann's rule and/or reflect the time it takes for an introduced pathogen to spread geographically, add an additional layer for how mammalian species respond to pathogen exposure. Our goal was to understand how hosts less susceptible to pathogen infections respond to long‐term pathogen exposure across a broad latitudinal gradient. We examined changes in body …
