Physiological Approach To Characterize Drowsiness In Simulated Flight Operations During Window Of Circadian Low, Bijay Guragain

Theses and Dissertations

Drowsiness is a psycho-physiological transition from awake towards falling sleep and its detection is crucial in aviation industries. It is a common cause for pilot’s error due to unpredictable work hours, longer flight periods, circadian disruption, and insufficient sleep. The pilots’ are prone towards higher level of drowsiness during window of circadian low (2:00 am- 6:00 am). Airplanes require complex operations and lack of alertness increases accidents. Aviation accidents are much disastrous and early drowsiness detection helps to reduce such accidents. This thesis studied physiological signals during drowsiness from 18 commercially-rated pilots in flight simulator. The major aim of the …

The Impact Of Historical Trauma On Alcohol Use And Academic Outcomes In American Indian College Students, Elizabeth Luger

Theses and Dissertations

Issues regarding substance use, particularly alcohol use, and academic outcomes are two factors that are vital to examine when researching the quality of life and academic success of American Indian (AI) college students. Because AI college students comprise a relatively small percentage of the general college population, the majority of research conducted using college student samples tends to focus on Caucasian (CA) subjects or all ethnicities combined – neither of which directly pertain to furthering understanding surrounding issues specific to AI college students. One factor that has been shown to predict alcohol use among AIs is historical trauma, which is …

Potentials Of Physiological Signals To Implement A Wearable Drowsiness Detection And Warning System For Pilots, Shubha Majumder

Theses and Dissertations

Drowsiness is a transitional psychophysiological state from alertness towards sleep, which decreases concentration and increases response time. Drowsiness during duty hours is common for in-flight pilots due to frequent travel across different time zones, extended duty hours as well as circadian rhythm disruption. Hence, drowsy flying is one of the leading reasons for increased risk of accidents, especially in commercial aviation. Mainly three approaches (i.e., vehicle-based, behavioral, and physiological signal based) are used for onboard drowsiness detection. Among them, physiological signal-based approach is advantageous for early detection of drowsiness with reasonable accuracy due to the strong relationship among some of …

Risk-Taking Behaviors As Predicted By (Mal)Adaptive Functioning In College Students: A Look Into Emotional Adjustment, Hillary Smith

Theses and Dissertations

Risk-taking behaviors emerge, increase, and peak during adolescence and have shown to continue into late adolescence. Research has begun to explore how some forms of risk-taking may be normative and adaptive. The aim of this study is to look at how social, academic, and occupational functioning are related to risk-behaviors, as measured by risk-favorability and reported risk-taking history, and emotional adjustment in a college sample (N=314). Risk was assessed using self-report and an implicit task, both of which were moderately correlated. Both risk measures were negatively correlated with self-report measures of adaptive functioning and emotional adjustment.A series of mediation analyses …

These professionals create policy, write laws, and advocate on behalf of others. They are leaders and experts who possess enormous power, and we rely on them to make decisions that will allow our society to thrive. In recent decades, however, our …

Temporal Trends In The Grip Strength Of Children And Adolescents, Faith Lavoy Dooley

Theses and Dissertations

Objective: To estimate national and international temporal trends in the handgrip strength of children and adolescents, and to examine relationships between trends in handgrip strength and trends in health-related and sociodemographic indicators.

Methods: Data were obtained in two ways: (a) through a systematic electronic database search for studies reporting on temporal trends in the handgrip strength of apparently healthy 9–17-year-olds, (b) pearling reference lists, topical systematic reviews and personal libraries, and (c) by examining large national fitness datasets suitable to temporal trends analysis. Sample-weighted temporal trends were estimated using best-fitting regression models relating the year of testing to mean handgrip …

Photography Methods To Understand Rural Resilience And Environmental Literacy: The Example Of Fracking In The Bakken, Bruce Evan Farnsworth

Theses and Dissertations

This dissertation examines the social and environmental impacts of fracking through deep ethnographic interviews and observations with farmers and ranchers living and leasing on the Bakken and Three Forks shale oil formations of western North Dakota, currently the second largest oil-producing region in the United States. This study investigates how photographic methods such as photo elicitation, repeat photography, and aerial photographs/maps elicit local knowledge and testify to the resilience of ranchers and farmers challenged by oil development and the alteration of their environment. Motivated by heritage, political marginalization and the pervasive loss of ruralness, the participants express several roles, among …

United States Coast Guard Aviation Safety: Relationship Between The Safety Survey And The Extent Of Hazard Reporting, James Cooley

Theses and Dissertations

Aviation safety outcomes, such as mishaps, are a product of an aviation organization’s safety culture (Reason, 2008; Reiman & Pietikäinen, 2012). Safety cultures should be assessed in order to improve an organization’s state of safety (Adjekum et al., 2015; Cooper, Collins, Bernard, Schwann, & Knox, 2019; Wiegmann, Zhang, von Thaden, Sharma, & Gibbons, 2004). Questionnaires are one of the best ways of obtaining information about an organization’s safety culture (Wiegmann et al., 2004; Wald, Gray, & Eatough, 2018). Additionally, the extent to which aviation hazards are reported (hazreps) serve as an indicator of the health of an aviation Safety Management …

Examining Self-Regulation Of Learning Among Community College Students In Developmental Mathematics Courses, Katrina M. Eberhart

Theses and Dissertations

The ability to self-regulate one’s learning is crucial to the success of all college students, but is particularly important to those who are considered to be underprepared; it puts students on a path towards successful course completion, subsequent course enrollment, and eventual graduation from a postsecondary institution. Those enrolled in remedial coursework are a large portion of students labeled as underprepared. Remedial education is a contentious topic in higher education. Thus, it is critical to investigate the use of classroom strategies to foster a self-regulated environment to support student success in these early classes and move onto the classes needed …

Thermal Performance Analysis Of The Liquid Cooling And Ventilation Garment (Lcvg) With Respect To Tubing Geometry, Kayla Marie Daniels

Theses and Dissertations

The technology of a liquid-cooled garment allows astronauts to complete extravehicular activities while maintaining a degree of thermal comfort. The garment has gone largely unchanged despite advancements in technology, materials, and knowledge. This research examines possible advancements in thermal efficiency with an alternate tubing geometry through heat transfer rate calculations. A semi-circle cross-section was selected and compared against the current circular cross-section tubing. Each tubing cross-section was 3-D printed and integrated into forearm sleeves. For comparison, the assembly of each sleeve resembled the current Liquid Cooling and Ventilation Garment used with the Extravehicular Mobility Unit. Subjects wore the forearm sleeves …

Measuring Friendship Maintenance In Gay Men, Eliah Reding

Theses and Dissertations

This dissertation examines the existing friendship maintenance literature to develop a psychometrically sound scale for the measurement of friendship maintenance among gay men. Existing friendship maintenance research does not adequately capture the uniqueness of gay male friendship. Utilizing DeVellis’s (2016) steps of scale development, this dissertation constructs a new scale, the GayFABS, to assess the unique aspects of friendship maintenance in gay men. Unique in this dissertation is the use of a focus group to establish content validity rather than the traditional approach of expert review. An exploratory factor analysis is conducted to structure the scale and its component subscales. …
