Small Unmanned Aircraft Systems: Operator Workload And Situation Awareness Utilizing First Person View Techniques, Ross Lucas Stephenson Jr
Doctoral Dissertations and Master's Theses
The small, unmanned aircraft systems (sUAS) sector within the aviation industry is experiencing unprecedented growth. However, the regulatory guidance for the safe integration of sUAS into the National Airspace System (NAS) has not kept pace with this technological growth within the market. Current regulatory limitations of line-of-sight operations may have an impact on the establishment of an equivalent level of safety for sUAS operations as maintained by manned aircraft. The focal point of the discussion of line-of-sight operations has been the ability of the sUAS pilot to see and avoid all obstacles and other aircraft in a safe and timely …

The Right Sign For The Right Time: A Look At The Effectiveness Of Different Types Of Signage, Samantha Emily Feldstein
Senior Projects Fall 2023
Warning signs are present in the day to day lives of most individuals. While there has been past research into what makes a warning sign more or less effective, there is still no clear answer as to what the most effective warning sign looks like. This study looks at specifically the words being used on a sign and the sign's color to determine which has a larger impact on the hazard perception of the sign. An online study was conducted in which participants were shown different signs and asked to rate how hazardous of a situation they thought each sign …
Examining The Relationship Of Race On Students’ Perceptions Of Safety And Concealed Campus Carry On A University Campus, Whitney H. Mascaro
Examining The Relationship Of Race On Students’ Perceptions Of Safety And Concealed Campus Carry On A University Campus, Whitney H. Mascaro
Graduate Theses, Dissertations, and Problem Reports
Previous literature suggests that students who feel unsafe in their academic settings experience harmful academic, social, and psychological ramifications. With an alarming increase in school shootings, violence, and media coverage, the political discourse surrounding gun violence and strategies to ensure safety on college campuses has become increasingly polarized. States like Texas, Georgia, and Colorado have passed bills allowing students to carry concealed handguns on university campuses. At the time of this study, the state legislature in West Virginia passed a similar bill known as the Campus Self-Defense Act (Senate Bill 246, 2021). College students who identify as Black, Indigenous, People …
Effects Of Chronic Stress On Safety Processing And Physiology In The Medial Prefrontal-Amygdala-Basal Forebrain Circuit, Itamar S. Grunfeld
Effects Of Chronic Stress On Safety Processing And Physiology In The Medial Prefrontal-Amygdala-Basal Forebrain Circuit, Itamar S. Grunfeld
Dissertations, Theses, and Capstone Projects
Chronic stress increases generalization of fear to non-threatening cues, a key symptom in numerous psychiatric mood disorders. However, the mechanisms through which stress impacts safety learning remain poorly understood. To probe the relationship between stress and safety learning, this dissertation employed multiple behaviors, in conjunction with in-vivo multisite physiology during explicit safety and fear discrimination learning. In Chapter 1, I outline the role of chronic stress in driving neurological adaptations that result in generalized fear and highlight how this occurs because of impaired safety cue encoding. In Chapter 2, I show that chronic stress in the form of social defeat …
The Effects Of Cost, Level Of Safety, And Severity Of Injury On Manager Decisions To Implement A Safety Solution, Jonathan M. Hochmuth
The Effects Of Cost, Level Of Safety, And Severity Of Injury On Manager Decisions To Implement A Safety Solution, Jonathan M. Hochmuth
Dissertations
Workplace injuries continue to be a source of substantial human and financial costs each year. Behavioral safety processes have been effective in reducing workplace injuries by increasing safety-related behaviors. In recent years, the focus in behavioral safety has shifted towards the role of managers in establishing and maintaining safe behaviors and conditions in the workplace. Understanding how managers make decisions to allocate resources is critical to improving safety. The field of behavioral economics has developed methods for studying decision-making. While there have been calls to apply these methods to occupational safety, there are only two empirical studies which have done …

Sirencide: The Impact Of Acute Stress On Emergency Vehicle Crashes, Dustin Lambert
Dissertations
Emergency services provide an invaluable service to communities and cities around the world. Research has shown these professionals encounter significant acute psychological stress throughout their work shifts. Acute stress has been shown to impact human performance in various realms, from increased risk-taking to cognitive decline. While the actual work varies between firefighters, law enforcement, and emergency medical services, a shared commonality is the operation of emergency vehicles. Emergency vehicle crashes are recognized as a serious issue by FEMA. The current work aimed to measure the impact of acute stress on emergency responders as measured by fatal emergency vehicle crashes in …
Dance/Movement Therapy In Response To Continuous Race-Based Trauma, Aliesha Bryan
Dance/Movement Therapy In Response To Continuous Race-Based Trauma, Aliesha Bryan
Dance/Movement Therapy Theses
Trauma is concomitant with a lack of safety; as such, where there is a threat to safety, there is likely to be trauma. Afrodescendants living in the United States, through an ongoing lack of human regard, are often powerless to ensure their safety, and are regularly subjected to continuous, race-based trauma. Racism is deeply embedded in the nation’s institutions as well as in every relationship, and this deeply pervasive and penetrating ideology influences strongly how individuals of any race interact with others. Race-based aggression, from micro- to macro-, has a profound and continuously traumatizing effect on Afrodescendants, with similarly profound …

Correlation Between Moral Foundations And Students’ Attitudes Toward Concealed Carry Guns On College Campuses, Hengameh Hashemi Toosi
Walden Dissertations and Doctoral Studies
Correlation between Moral Foundations and Students’ Attitudes Toward Concealed Carry Guns on College CampusesAbstract Attitudes towards concealed carry of guns (CCG) on campus are diverse across society and within college and university communities. The purpose of this quantitative study was to investigate possible predictors of college students’ attitudes toward CCG on college campuses. Using the moral foundations theory, it was hypothesized that students’ types of moral foundations, political affiliations, and demographics would predict four dimensions of attitudes toward CCG at their college campuses. The prediction model included gender, race, political affiliation (PA), as well as scores for harm (H), fairness …
A Comparison Of Traditional Aggregated Data To A Comprehensive Second-By-Second Data Depiction In Functional Analysis Graphs, Erin Mackelvie
A Comparison Of Traditional Aggregated Data To A Comprehensive Second-By-Second Data Depiction In Functional Analysis Graphs, Erin Mackelvie
University of the Pacific Theses and Dissertations
Functional analyses (FAs) are an important component of treatment and the data gathered from FAs are often graphed in an aggregate or summary format, such as mean rate per session. Given the prevalence of undifferentiated analyses, it may be that this common method of data depiction is incomplete. In this paper, we compare the traditional aggregate method to a comprehensive second-by-second demonstration of the data including all appropriate and inappropriate responses emitted, as well as programmed and accidental antecedent and consequent variables, which may help further clarify the results of a functional analysis. We compared the functional analysis results of …
Effect Of Short-Storage Hrgcs On Driver Decision Behavior And Safety Concerns: Real-World Analysis And Experimental Evidence, Anne Linja
Dissertations, Master's Theses and Master's Reports
Vehicle-train collisions at highway-rail grade crossings (HRGCs) continue to be a safety concern, and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as HRGCs with limited space between the railroad tracks and the highway intersection, may create additional cognitive burdens for drivers. We investigated the effect of HRGC type (short-storage vs. non-short storage) on driver attention and decision-making in two studies. In Study 1, we systematically analyzed 996 incidents from 2017-2019 from the Federal Railroad Administration’s Safety database. Driver decision making and outcomes were different depending …
A Comparison Of The Efficacy Of Gutter Pan And Curb Top Placement With A Full Gateway Configuration Of The In-Street Sign On Driver Yielding To Pedestrians, Erik Newton
Masters Theses
Driver yielding behavior at crosswalks directly affects pedestrian safety. In this study we examined whether the placement of the signs in the gutter pan or on top of the curb, while using a full gateway configuration of the in-street sign, influenced the efficacy of the treatment. Data were collected at sites using both in gutter and on top of curb full gateway configurations. The gutter pan configuration resulted in a higher percentage of driver yielding behavior to pedestrians in the crosswalk. The gateway treatment was shown to be more effective in the gutter pan configuration than the curb top configuration …
The Effects Of Performance Feedback On Behavioral Self-Monitoring, Noell Jankowski
The Effects Of Performance Feedback On Behavioral Self-Monitoring, Noell Jankowski
Theses and Dissertations
Self-monitoring is a process in which an individual observes and records their own behavior. In the field of behavior analysis, there is limited research on behavioral self-monitoring (BSM) and the components that are necessary to maintain its effects. Therefore, the purpose of the current study was to identify effects of implementing a feedback intervention with BSM on participants’ compliance in completing BSM tasks. Participants were three undergraduate students at a southeastern university who self-monitored their own safe driving behaviors in their personal vehicles. The independent variable was the implementation of a feedback intervention and the dependent variable was compliance with …
Behavioral Skills Training For Active Shooter Scenarios: Human Service Staff, Jacqueline Marie Noto
Behavioral Skills Training For Active Shooter Scenarios: Human Service Staff, Jacqueline Marie Noto
Theses and Dissertations
Active shooter scenarios have become increasingly prevalent in school and healthcare settings. Unfortunately, little information is available on training for active shooter scenarios when a staff member is also responsible for a client. Behavioral skills training has been shown to be an effective way to train safety skills in prior research. We found that behavioral skills training was more effective than an informational video at increasing correct responses to three different active shooter scenarios among three behavioral clinicians. These findings may impact how active shooter training is conducted.
High School Students' Perceptions Of Safety Concerns Predicts School Avoidance, Ann Marie Howard
High School Students' Perceptions Of Safety Concerns Predicts School Avoidance, Ann Marie Howard
Walden Dissertations and Doctoral Studies
School violence is a growing concern and an impending danger for American youth. Students' perceptions of violent school incidents may lead to fear and this fear may lead to school avoidance. Although researchers have found that teenage pregnancy and working to support family are two of the main reasons that students stay home from school, there has been no research conducted on whether students' perceptions of safety concerns, solely focusing on the presence of guns, gangs, student bullying, and fear of victimization, predict their decision to stay home from school. Therefore, based on social disorganization and resilience theories, the purpose …
Recognizing And Anticipating Stress Related Complacent Behavior In Manufacturing Industries, Ricardo Alberto Pineda
Recognizing And Anticipating Stress Related Complacent Behavior In Manufacturing Industries, Ricardo Alberto Pineda
Walden Dissertations and Doctoral Studies
Numerous safety studies suggest that stress complacency related accidents in manufacturing industries continue to cause injuries or fatalities because of the absence of emotional resources for leaders, who are unable to prevent accidents when these conditions exist. Leaders of the manufactory industries may not have the appropriate emotional measures which are significant to recognize employees' underlying complacent behavior. The purpose of this quantitative correlational study was to evaluate the relationship between leaders' emotional intelligence resources and their ability to manage to prevent injuries and fatalities in the workplace. The research questions address key traits of emotional intelligence regarding emotional perceptions …

The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth
The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth
Masters Theses
The gateway in-street sign treatment has been demonstrated to be a cost-effective method for increasing driver yielding behavior at crosswalks. In the present study, wide and narrow gateway widths were compared at two sites to determine if there was a differential effect on driver yielding behavior. Then, the relationship between width and yielding was refined with a parametric analysis at one of these sites. Gateway width was varied in two-foot intervals from 12ft to 18ft. The results indicated an inverse relationship between gateway width and driver yielding behavior. There are likely two variables related to this effect. First, because drivers …
How Can The Attunement Needs Of Children With Disorganized Attachment Styles Be Supported Through Expressive Arts Therapy?, Jayne Paley
Expressive Therapies Capstone Theses
Treatment strategies for school age children with disorganized attachment are not well established. This population exhibits a range of difficulties in social relationships and self-regulation. Additionally, children with disorganized attachment generally rely on defense mechanisms and present with other comorbid conditions, adding to the complexity of treatment. This paper explores current research and theories about disorganized attachment and then, on the basis of evidence provided throughout this paper, proposes the concept of attunement needs in relation to working with children with disorganized attachment. The attunement needs described in this paper, derived from the literature, include safety/security, control/power, consistency, affective release, …
Mindfulness As A Vigilance Intervention: Examining Its Impact On Stress And Mental Demand, Kelli Huber
Mindfulness As A Vigilance Intervention: Examining Its Impact On Stress And Mental Demand, Kelli Huber
Dissertations
Occupations involving vigilance performance (i.e., sustained attention in monitoring for rare environmental threats) are known to experience vigilance decrement, a decline in performance over time. These occupations are known to be cognitively and emotionally challenging, giving rise to harmful effects for employees in them and presenting safety implications for the welfare of others. The current study investigated mindfulness as a potentially viable intervention to alleviate outcomes of vigilance demands: stress and mental demand. A mindfulness induction was compared to an unfocused control condition in which both were administered during a break from a vigilance task, specifically, a baggage screening task. …

How Graduate Experience Changes Beliefs In Working With Culturally And Linguistically Diverse Populations: A Survey Study, Stephanie Bove
All Graduate Theses, Dissertations, and Other Capstone Projects
Speech-language pathologists work in a variety of settings that require savvy transitions between patients from many cultures and backgrounds. Graduate students may get little practice working with culturally and linguistically diverse populations depending upon where they perform their practicum and internships. Researchers at a mid-western university developed a survey to collect student perspectives regarding cultural competence. A single cohort received the survey at three intervals to track a change in responses from the beginning of their first year of graduate school through their clinical fellowship. Students took a Multicultural Issues class between their first and second survey responses. Data collected …
Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng
Open Access Theses
Post traumatic stress disorder (PTSD) patients frequently show impairment in safety learning (Jovanovic, Kazama, Bachevalier, & Davis, 2012). Since the amygdala is known to be critical for emotional processing(Wassum & Izquierdo, 2015) and dopamine signaling in the amygdala is important for mediating both fear and reward learning, current experiments examined the role of dopamine signaling in the BLA in mediating both safety learning and reward seeking. We manipulated dopamine D1 receptor activity with a D1 receptor agonist (SKF 38393) or D1 receptor antagonist (SCH23390) either systemically or infused directly into the BLA 20 minutes prior to training rats in a …
Housing Choices Among Homeless Families In Child Welfare: A Mixed Methods Study, Anne Rufa
Housing Choices Among Homeless Families In Child Welfare: A Mixed Methods Study, Anne Rufa
College of Science and Health Theses and Dissertations
A growing body of research has identified a link between housing instability and involvement with child welfare services for families. For some, inadequate housing situations lead to parent-child separations or delayed reunification. Housing assistance may be one option for these families to avoid these outcomes; however, little research examines existing housing services for inadequately housed families in contact with the child welfare system. Public housing assistance represents the primary source to connect low-income families with affordable housing; however, a number of barriers challenge navigation of this system, including long waitlists, stigmatization of voucher use, and stringent eligibility requirements for all …

Increasing Caregiver Supervision Of Young Children: Teaching Scanning, Predicting Behavior, And Modifying For Safety, Natalie Truba
Dissertations
Unintentional injuries account for a significant number of child deaths and visits to the emergency department. Although increased supervision is routinely shown to be an effective method of preventing unintentional childhood injuries, few interventions systemically teach caregivers behavioral skills to supervise their children appropriately. The present study utilized a multiple baseline design to pilot test an intervention designed to increase caregiver supervision and decrease unintentional childhood injuries by training caregivers how to provide appropriate levels of supervision for their young children (ages 6 to 36 months). Specifically, caregivers were taught in the present study include: (1) scanning the environment (for …

Workplace Aggression, Safety Performance, And Safety Outcomes, Mediated By Burnout And Moderated By Psychological Capital (Psycap), Daniel Wiegert
Workplace Aggression, Safety Performance, And Safety Outcomes, Mediated By Burnout And Moderated By Psychological Capital (Psycap), Daniel Wiegert
Wayne State University Theses
The Bureau of Labor Statistics reports that in 2013, there were over four thousand work-related fatalities and over 1.1 million workplace accidents, with a cost to organizations due to these losses estimated to be over 2 billion dollars. The purpose of the current study is to identify workplace aggression as an antecedent of safety behaviors (i.e., safety performance and workplace accidents and injuries (i.e., safety outcomes), along with burnout as a mediator. Additionally, Psychological Capital (PsyCap) was proposed as a moderator (buffer) of the hypothesized mediational relationships. The Job Demands-Resources Model Conservation of Resources, and Lazarus and Folkman’s (1987) Transactional …
Leaving Home: Investigating Transitioning Challenges Faced By Boarding Students And Their Families, Kate Margaret Hadwen
Leaving Home: Investigating Transitioning Challenges Faced By Boarding Students And Their Families, Kate Margaret Hadwen
Theses: Doctorates and Masters
Transitioning to boarding school during the middle years of childhood impacts upon the social, emotional and academic wellbeing of young people (Bramston & Patrick, 2007; Connell & Wellborn, 1991; Deci, Vallerand, Pelletier, & Ryan, 1991; Earls & Carlson, 2001). Students who live at school as boarders, may experience greater transitional changes in all three components of wellbeing due to the extent of change experienced during this transition. While research addressing transitioning to school has indicated the importance of connectedness to school, bonding, friendships and a sense of autonomy (Eccles et al., 1993), there is limited research addressing the transitioning experiences …
Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang
Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang
Masters Theses
Motor vehicle crashes are a leading cause of death during adolescence, with the fatal crash rate per mile-driven for 16-19 years old drivers being nearly 3 times larger than the rate for drivers age 20 and older. High gravitational events among teenage drivers, such as quick starts, and hard stops, have been shown to be highly correlated with crash rates. The current younger driver training programs developed in the late 1990s, however, do not appear to be especially effective in regard to many skills which are critical to avoiding crashes. With this in mind, a simulator-based training program aimed at …
