Data fusion using weakly aligned sources

We introduce a new data fusion method that utilizes multiple data sources to estimate a smooth, finite-dimensional parameter. Most existing methods only make use of fully aligned data sources that share common conditional distributions of one or more variables of interest. However, in many settings, the scarcity of fully aligned sources can make existing methods require unduly large sample sizes to be useful. Our approach enables the incorporation of weakly aligned data sources that are not perfectly aligned, provided their degree of misalignment can be characterized by a prespecified density ratio model. We describe gains in efficiency and provide a general means to construct estimators achieving these gains. We illustrate our results by fusing data from two harmonized HIV monoclonal antibody prevention efficacy trials to study how a neutralizing antibody biomarker associates with HIV genotype.Comment: 33 pages including appendices, 3 figure

The Vulnerabilities of Hypoxic Events Within General Aviation

The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, their symptoms of hypoxia, as well as whether or not that pilot deemed the event to put them in an unsafe flight condition. The results of this study showed not only those that were impacted the greatest by hypoxia, but also a caring concern for reporting these events to better flight physiology training. The key elements for this research were: Level of pilot experience who have experienced hypoxia Reporting statistics Symptoms experienced Suggestions for bettering flight physiology trainin

General Aviation Hypoxia and Reporting Statistics

“All too often, pilots tell me they don\u27t need physiological training because they don\u27t fly that high. The statement points out the general feelings of a large majority of the aviation population. I suppose then the burning question is ‘why do we still have aircraft accidents?’” (Boshers, 2015). To this day there are no statistics on how often general aviation pilots experience hypoxia during everyday operations. General aviation pilots (i.e. non-commercial operations) were chosen for this study because: Little regulation regarding flight physiology training General attitude of invulnerability towards hypoxia No requirement to report hypoxia or similar event

Modelling Fatigue for Management Decision Making: A Case Study

Fatigue is one major contributing factor that reduces the human ability and leads to accidents, and threatens the safety of aircraft and human lives. Though fatigue is seen in all the disciplines associated with the aviation industry, this paper will discuss only pilot fatigue. Based on the literature examined, this study first examines the significance of the problem. Investigation of the inflight, pre/post flight countermeasures (both pharmacological and non - pharmacological methods) practiced at present, discusses the Fatigue Risk Management System (FRMS) – in this first, it defines the FRMS, briefly discusses its history, describes the organizational structure of FRMS

The Utilization of Peer Mentorship and its Positive Impact on Student Retention

In recognition of increasing rates of repeated ground schools and flight lessons, in combination with decreasing retention rates in the flight programs at Embry-Riddle Aeronautical University, the Department of Aeronautical Science in the College of Aviation took initiative to create a program that identified struggle students before they reached excessive failure or financial distress. The students identified in the Student Success Initiative (SSI) after being assessed would be required to attend a mediation session with their academic and flight training staff in order to create a specialized training program. Student Success Initiative (SSI) Identifies at risk students Implemented training plan tailored to student One-on-one instructio

Undergraduate Research on General Aviation Hypoxia: A Student\u27s Perspective

The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, as well as whether or not that pilot reported the occurrence to the proper establishments. The results of this study showed not only those that were impacted the greatest by hypoxia, but also a caring concern for reporting these events. The key elements for this research were: • Level of flying experience that encountered hypoxia • Reporting statistics • Reasons for not reporting the event • Suggestions for bettering flight physiology trainin

Building Student Success and Retention through an Enhanced Peer Counseling Program

Fatigue and Its Management in the Aviation Industry, with Special Reference to Pilots

Abstract Fatigue is a significant contributing factor that reduces human ability and leads to accidents and threatens the safety of aircraft and human lives. Approximately 70% of fatal accidents that occur in commercial aviation operations are due to human factors. More specifically, crew fatigue contributes to nearly 15 to 20% of the accidents (Akerstedt, 2000). These accidents and incidents are associated with pilot fatigue because of the long duty periods, disruption of circadian rhythms, and inadequate sleep that are common among both commercial and military pilots. Though fatigue is seen in all the disciplines associated with the aviation industry, this paper will discuss only pilot fatigue. Based on the literature examined, this paper first defines fatigue, examines the significance of the problem, discusses what is fatigue, its types and causes, discusses fatigue-related accidents and incidents, examines fatigue in different flight operations and its impact on the wellbeing of pilots, investigates the in-flight and pre-/post-flight countermeasures (both pharmacological and non-pharmacological methods) practiced at present, and discusses the fatigue risk management system (FRMS)—in this it defines FRMS, briefly discusses its history, describes the organizational structure of FRMS, its process, and its operation in the aviation industry, merits and demerits of FRMS, and its future applications. The paper finally concludes with some recommendations for future research/study in this discipline

Peer Counseling for Student Success in University Flight Education: A Case Example

In response to attrition rates, the Department of Aeronautical Science in the College of Aviation at Embry-Riddle Aeronautical University in Prescott, AZ, analyzed how best to identify and assist students who were struggling with their flight training. In order to maximize student retention, students at risk must be identified early, prior to training failure or financial distress. The assessment of these findings of the flight program and the attrition rates resulted in a “Student Success Initiative” (SSI) being established that would identify students approaching ‘at-risk’ points in flight training, both fixed-wing and helicopter. These students would be assessed and ultimately required to attend an intervention session with support staff in coordination with his/her academic faculty advisor and/or flight staff. This meeting concludes with a contract of expectations signed by the student that includes a plan of action and specific timelines. One critical challenge in the implementation of the SSI program was to find an effective way to provide support for students in the program. The answer was to develop a program manned by “peer counselors” to provide tutoring and other support resources for students in need of help

Maximizing Student Achievements: Mastering Aviation English

Flight training delays and corresponding increased costs appear to be widespread among universities with aviation programs. Students in these programs have to juggle demanding academics and flight training. Additionally, international students, for whom English is not their primary language, have the added disadvantage of learning complex aviation concepts in English. In order to maximize retention in collegiate flight programs, an experimental aviation English course has been designed to help frontload aviation vocabulary and take a proactive approach to teaching language skills that are essential in flight training
