Evaluation Of A Scientifically Developed Anesthesiology Handoff Protocol, Kristen Lise Welsh Webster
Evaluation Of A Scientifically Developed Anesthesiology Handoff Protocol, Kristen Lise Welsh Webster
Doctoral Dissertations and Master's Theses
Communication failures have been cited as the leading cause of avoidable adverse events in healthcare. Specifically, within handoffs, these communication failures can cause error in the transfer of patient information. A multitude of factors can affect the transmission of patient information between providers including transactive memory, power distance, and conversational noise; however, literature suggests that the use of handoff protocols assist in improving communication and efficiency during handoffs. Studies regarding handoffs have typically centered on the content or delivery of the information during the handoff. To date, none have targeted the underlying mechanisms of the communication and their effects on …

Adaptive Learning Pedagogy In Udl And Multi-Modal Training, Ziho Kang, Mattlyn R. Dragoo, Randa L. Shehab, Han Yuan, Lei Ding, Stephen G. West
National Training Aircraft Symposium (NTAS)
Currently, most learning methods are based on classroom teaching through unidirectional communication using boards or slides. However, the Universal Design for Learning (UDL) asserts that the students can increase their performance if the instructors can provide the students with diversified information representation, expression, and engagement means. Although UDL minimizes the mismatch between the teaching and learning styles, we lack the detailed methods to implement the UDL and its associated multi-modal training methods in the context of air traffic control candidates and/or technical operators. We propose an approach that adapts the Index of Learning Styles (ILS) based on four categories: perception, …

Space Analysis And Research Centers (Sparcs) For Ssa Data And Analytics, Phillip Cunio, Brien Flewelling
Space Traffic Management Conference
Widespread use of massive data and increasing reliance on spaceborne infrastructure are two of the emerging megatrends of the early 21st century. However, both come with liabilities: movement and processing of large data volumes is very expensive, and reliance on spaceborne infrastructure adds risk that problems in the still incompletely-understood space domain might cause work disruptions.
ExoAnalytic proposes the use of Space Analysis and Research Centers (SpARCs) as a way to begin addressing both these issues. A SpARC is a facility which integrates volumes of data collected on satellites, centrally analyzes it, and makes available resulting useful information. The …

Examining Time To Evacuate Dynamically Activated Aircraft Hazard Areas, Zheng Tao, Granghuai Wang, Ashley G. Williams, Jon L. Semanek, Jonathan L. Schwartz
Space Traffic Management Conference
The growth in launch and reentry operations in the National Airspace System (NAS) presents the Federal Aviation Administration (FAA) with the challenge of integrating them more efficiently while also minimizing effects on other NAS users and maintaining safety. Currently, to maintain safety and account for unforeseen events such as vehicle breakup, the FAA segregates large amounts of airspace, called Aircraft Hazard Areas (AHAs), from traditional NAS users during launch and reentry operations. In order to minimize effects on NAS users, some AHAs during reentry are dynamically activated only if an unexpected event occurs. If a dynamic AHA is activated, then …

International Journal of Aviation, Aeronautics, and Aerospace
As is well known, the integration of small Unmanned Aircraft Systems (sUAS) or “drones” into the National Airspace System (NAS) has captured significant industry, academic, regulatory and media attention. For sUAS that typically fly low and slow, the possibility of a mid-air collision with a nearby general aviation aircraft needs to be studied from a system safety perspective to identify possible hazards and to assess mitigations. The Aviation System Risk Model (ASRM) is a first-generation socio-technical model that uses a Bayesian Belief Network (BBN) methodology to integrate possible hazards to assess a non-linear safety risk metric. Using inductive logic, the …

Sub-Orbital Spaceflight – An Addition To Our Multi-Modal Transportation System, Scott Haeffelin
Space Traffic Management Conference
The number of commercial spaceflights will be increasing by orders of magnitude over the next several decades. The current volume of space traffic can be managed on a case-by-case basis and there is little impact to the National Airspace System (NAS). This will change as more spaceports become operational, commercial sub-orbital flight companies begin serving their customers and as the cost of these flights begin to decrease. Current regulatory paths seek to allow the flexibility in the regulations for this industry to flourish while also maintaining a high standard of safety. There are, however, many nearsighted and old fashioned assumptions …

Space Traffic Management Conference
Weather has a large affect on operations at Cape Canaveral Air Force Station (CCAFS) and NASA Kennedy Space Center (KSC). Weather is the leading source of scrubs and delays to space launch from CCAFS/KSC. Weather has an even larger impact on ground processing as space launch vehicles and payloads are prepared in the months before space launch. Many of those operations are very sensitive to weather. In addition, the weather in Florida is notoriously difficult to predict, especially during the summer when rapid deep convection can occur in minutes. Finally, the weather can be extremely subtle in this area during …

Evaluating Dynamic ‘Landing Gear Unsafe’ Auditory Alerts As A Defense Against Habituation, Vincenzo Fasano
Evaluating Dynamic ‘Landing Gear Unsafe’ Auditory Alerts As A Defense Against Habituation, Vincenzo Fasano
Doctoral Dissertations and Master's Theses
Auditory alerts are widely used in today's daily routine. Unlike their visual counterparts, auditory alerts can be used to capture someone's attention, even though the user is not within visual range. As beneficial as auditory alerts can be, it is possible to become habituated to alerts. Habituation is the elimination of a response as a result of continuous exposure to a stimulus. In this small-scale study, methods to reduce pilot habituation to the 'landing gear unsafe' auditory alert were investigated. Ten subjects executed eight non-precision instrument approaches that exposed the subjects to the 'landing gear unsafe' auditory alert for a …

Level Of Agreement In The Mental Models Of Human Factors Practitioners And Systems Engineers Working In Collaborative Teams, Jerry A. Gordon
Doctoral Dissertations and Master's Theses
Emerging research in complexity science recognizes traditional techniques for engineering systems do not always work for complex systems. Designing complex systems requires individuals to have knowledge of engineering as well as human performance. To this end, design efforts rely often on multi-disciplinary teams. While any two members of a design team may view the system design problem in vastly different manners, this study sought to identify a possible systemic effect on approach by the differing education and experience obtained by social practitioners, represented by human factors, and technical practitioners, represented by systems engineers. It further examined the impact of the …
Determining Kanban Size Using Mathematical Programming And Discrete Event Simulation For A Manufacturing System With Large Production Variability, Abigail Michele Gaston
Determining Kanban Size Using Mathematical Programming And Discrete Event Simulation For A Manufacturing System With Large Production Variability, Abigail Michele Gaston
Doctoral Dissertations and Master's Theses
In order to become more competitive and aggressive in the marketplace it is imperative for manufacturers to reduce cycle time, limit work-in-process, and improve productivity, responsiveness, capacities, and quality. One manner in which supply chains can be improved is via the use of kanbans in a pull production system. Kanbans refer to a card or signal for productions scheduling within just-in-time (JIT) production systems to signal where and what to produce, when to produce it, and how much. A Kanban based JIT production system has been shown to be beneficial to supply chains for they reduce work-in-process, provide real time …
Effects Of Visual Interaction Methods On Simulated Unmanned Aircraft Operator Situational Awareness, Brent A. Terwilliger
Effects Of Visual Interaction Methods On Simulated Unmanned Aircraft Operator Situational Awareness, Brent A. Terwilliger
Publications
The limited field of view of static egocentric visual displays employed in unmanned aircraft controls introduces the soda straw effect on operators, which significantly affects their ability to capture and maintain situational awareness by not depicting peripheral visual data. The problem with insufficient operator situational awareness is the resulting increased potential for error and oversight during operation of unmanned aircraft, leading to accidents and mishaps costing United States taxpayers between $4 million to $54 million per year. The purpose of this quantitative experimental completely randomized design study was to examine and compare use of dynamic eyepoint to static visual interaction …
Nurturing Systems Thinking: Developing A Framework Based On The Human Factors Analysis And Classification System (Hfacs) To Improve Systems Development Processes, Arjun Vijayanarayanan
Nurturing Systems Thinking: Developing A Framework Based On The Human Factors Analysis And Classification System (Hfacs) To Improve Systems Development Processes, Arjun Vijayanarayanan
Doctoral Dissertations and Master's Theses
Large systems engineering projects have an astonishingly high failure rate. The reasons hypothesized for such a high failure rate include the neglect of nonsalient system elements such as social and human or organizational aspects of systems. Social and human factors have long been known to be critical elements of systems that are frequently ignored (e.g., Goguen, 1994). Systems engineering processes can benefit and be improved by effective utilization of a framework that helps developers expand their attention and efforts beyond the salient aspects of the system and the development process. In the aviation field, the Human Factors Analysis and Classification …
