Interactions Of International Pilots' Stress, Fatigue, Symptoms Of Depression, Anxiety, Common Mental Disorders And Wellbeing, Marion Venus, Martin Grosse Holtforth

International Journal of Aviation, Aeronautics, and Aerospace

Objective

This study Investigates more dimensions than previous studies simultaneously: pilots’ duty rosters, stress, sleep difficulties, fatigue levels, wellbeing, symptoms of depression, anxiety, and common mental disorders (CMD), and how they are interrelated.

Background

Several scientific studies have confirmed that fatigue can pose a significant risk to flight safety. Other studies reported positive depression screening results for more pilots, compared with the general population.

Method

A cross-sectional online survey was completed by 406 international pilots, who reported their duty rosters of the last two months. Pilots also self-assessed their stress-levels, sleep problems, fatigue, wellbeing, and mental health.

Results

Although pilots …

Comparison Of Schedules, Stress, Sleep Problems, Fatigue, Mental Health And Well-Being Of Low Cost And Network Carrier Pilots, Marion Venus

International Journal of Aviation, Aeronautics, and Aerospace

Objective

This research investigates and compares working-conditions, duty rosters, stress, sleep problems, fatigue levels, mental health, and well-being of pilots working for network (NWCs), and low-cost carriers (LCCs). This study extends previous research by investigating working conditions, pilots’ actual rosters, fatigue and mental health of two groups of pilots flying for LCC or NWC.

Method

A comprehensive cross-sectional online survey was completed by N=338 pilots (185 NWC, 153 LCC pilots). All pilots reported their roster data of the last 2 months during peak flight season, psychosocial and work-related stress (e.g., high job insecurity, less total flight-experience, lower income, more time …

Data Quality And Study Compliance Among College Students Across 2 Recruitment Sources: Two Study Investigation, Abby L. Braitman, Megan Strowger, Jennifer L. Shipley, Jordan Ortman, Rachel I. Macintyre, Elizabeth A. Bauer

Psychology Faculty Publications

Background: Models of satisficing suggest that study participants may not fully process survey items and provide accurate responses when survey burden is higher and when participant motivation is lower. Participants who do not fully process survey instructions can reduce a study’s power and hinder generalizability. Common concerns among researchers using self-report measures are data quality and participant compliance. Similarly, attrition can hurt the power and generalizability of a study.

Objective: Given that college students comprise most samples in psychological studies, especially examinations of student issues and psychological health, it is critical to understand how college student recruitment sources impact data …

A Meta-Analysis Of Associations Between Weight Bias Internalization And Conceptually-Related Correlates: A Step Towards Improving Construct Validity, Kelly A. Romano, Kristin E. Heron, Cassidy M. Sandoval, Lindsay M. Howard, Rachel I. Macintyre

Psychology Faculty Publications

Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and …

Organizational Commitment As A Mediator Between Organizational Climate And Employee Silence, Jennifer Sherer

Walden Dissertations and Doctoral Studies

Unethical organizational behavior negatively impacts organizations, and despite the benefits of whistleblowing, some employees are hesitant to report employee misconduct. The specific research problem examined factors that influence employee silence when confronted with employee misconduct. Prior researchers have explored how organizational climate and organizational commitment can contribute to or inhibit the decision to report misconduct. What remained unclear is how these factors may interact on their influence on employee silence. The purpose of this study was to examine whether organizational commitment mediated the relationship between organizational climate and employee silence. The theoretical foundations for this study were the social information …

Factors That Affect Anxiety And Acculturation In Syrian Emigrants, Thomas H. Anderson

Walden Dissertations and Doctoral Studies

Since the Syrian civil war began in 2011, more than 6 million Syrians have registered as refugees. Many displaced Syrians suffer myriad mental health disorders, including anxiety, which become a burden as they attempt to acculturate into a foreign culture. Research to understand the Syrian refugees has been conducted since the conflict began; however, the findings are inconsistent. Existing academic research does not adequately capture the depth of anxiety of Syrian emigrants, nor does it present an accurate picture of the challenges of acculturation. The purpose of this quantitative study was to examine the differences in anxiety and acculturation based …

The Effect Of Parental Socialization On The Postsecondary Plans Of Latino/Hispanic Students, Nilda Ivette Rosario

Walden Dissertations and Doctoral Studies

Latino/Hispanics are one of the largest ethnic minority groups in the United States, yet they are underrepresented in higher education. Grounded on the social cognitive theory and the Hoover-Dempsey and Sandler model, the purpose of this study was to examine the relationship between parental expectations, parental involvement, parental self-efficacy, and postsecondary planning of Latino/Hispanic students. The research questions were formulated to determine whether parental factors among Latino/Hispanic parents can predict postsecondary educational outcomes among Latino/Hispanic students. A quantitative correlational research study design was used. The target population was Latino/Hispanic parents residing in the United States with at least one child …

Relationships Among Burden, Quality Of Life, And Self-Efficcy In Careegivers Of An Older Family Member, Dr. Marietta Margaret Miller

Walden Dissertations and Doctoral Studies

AbstractInformal caregivers of a family member who has been dementia diagnosed play a substantial personal, social, and economic role in the care of their family member. However, this type of caregiving can have detrimental effects on a caregiver’s psychological, financial, physical, social, and emotional well-being. This quantitative study addressed possible relationships between caregiver burden and quality of life, and caregiver burden and self-efficacy as measured by the Zarit Burden Interview, the World Health Organization Quality of Life-BREF, and the Caregiver Self-Efficacy Scale. The theory of transactional stress and the stress process model provided the theoretical foundation. The participants of this …

Impact Of Trauma On Job Satisfaction And Turnover Intention Among Emergency Dispatchers, Sherrie Johnston

Walden Dissertations and Doctoral Studies

Emergency dispatchers in the United States are exposed to traumatic events, which may lead to a staffing shortage. Though it is well-established that decreased job satisfaction increases turnover intentions, little research investigates whether trauma impacts these constructs. Therefore, this quantitative non-experimental study was focused on whether education was a protective factor against posttraumatic stress disorder (PTSD) and whether trauma moderated the relationship between job satisfaction and turnover intention among emergency dispatchers. The relationship between vicarious trauma (VT) and PTSD among dispatchers was examined, and whether it is possible to predict PTSD among dispatchers based on VT, education level, and job …

Emotion And Judgment In Young Women Of A Society In Transition, Maura A. E. Pilotti, Khadija El Alaoui

International Journal of Transpersonal Studies

The present study asked whether emotional responses to narratives of moral transgressions are shaped by the reader’s assumed relationship with the injured party (i.e., oneself, familiar other, and unfamiliar other). Its goal was to test a cultural, religious, and individualistic account of such responses in young females of a traditional society in transition towards a sustainable integration into the global economy. To this end, female college students from the Kingdom of Saudi Arabia were asked to identify their emotional reaction to each of several moral transgressions, report its intensity and then judge the severity of the transgression. In agreement with …

Development Of An Explainability Scale To Evaluate Explainable Artificial Intelligence (Xai) Methods, Stephen Mccarthy

Dissertations

Explainable Artificial Intelligence (XAI) is an area of research that develops methods and techniques to make the results of artificial intelligence understood by humans. In recent years, there has been an increased demand for XAI methods to be developed due to model architectures getting more complicated and government regulations requiring transparency in machine learning models. With this increased demand has come an increased need for instruments to evaluate XAI methods. However, there are few, if none, valid and reliable instruments that take into account human opinion and cover all aspects of explainability. Therefore, this study developed an objective, human-centred questionnaire …

A Monte Carlo Simulation Of Rat Choice Behavior With Interdependent Outcomes, Michelle A. Frankot

Graduate Theses, Dissertations, and Problem Reports

Preclinical behavioral neuroscience often uses choice paradigms to capture psychiatric symptoms. In particular, the subfield of operant research produces nested datasets with many discrete choices in a session. The standard analytic practice is to aggregate choice into a continuous variable and analyze using ANOVA or linear regression. However, choice data often have multiple interdependent outcomes of interest, violating an assumption of general linear models. The aim of the current study was to quantify the accuracy of linear mixed-effects regression (LMER) for analyzing data from a 4-choice operant task called the Rodent Gambling Task (RGT), which measures decision-making in the context …

The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor

Capstone Showcase

Natural brain processes make all individuals susceptible to unconscious bias; however, stressful, fearful, or anger-evoking situations as well as the negative influence of media and social surroundings increase the risk of holding obstructive bias, and there is a greater risk of being negatively impacted by this phenomenon when belonging to a minority population (Rose & Flores, 2020). As a result, high rates of infant mortality (10.2 deaths per 1,000 live births for the Non-Hispanic Black population compared to 4.1 in the White population) and cardiovascular related diseases (190.0 cases per 1,000 in the Non-Hispanic Black population compared to 161.3 in …

The Effect Of Magnitude And Probability On Plea Bargain Decision-Making, Megan L. Small

Electronic Theses and Dissertations

Decision-making is studied in various aspects of life and can be especially vital in the context of the criminal justice system, such as plea bargains. Previous research in this area used a less commonly used task (fill-in-the-blank) in addition to a student sample (Falligant & Pence, 2019). The current study uses probability discounting to study the choice between accepting a plea bargain for a shorter incarceration sentence or risking a trial with a longer sentence on a sample of adults with experience in the criminal justice system. Three sentence durations, or magnitudes, were used (1 year, 5 years, and 25 …

Infant Motor Development Predicts The Dynamics Of Movement During Sleep, Aaron Demasi, Melissa N. Horger, Anat Scher, Sarah E. Berger

Publications and Research

The characteristics of infant sleep change over the first year. Generally, infants wake and move less at night as they grow older. However, acquisition of new motor skills leads to temporary increases in night waking and movement at night. Indeed, sleep-dependent movement at night is important for sensorimotor development. Nevertheless, little is known about how movement during sleep changes as infants accrue locomotor experience. The current study investigated whether infant sleep and movement during sleep were predicted by infants' walking experience. Seventy-eight infants wore an actigraph to measure physical activity during sleep. Parents reported when their infants first walked across …

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …

Student Attitudes Toward Science: Growth Trajectories And Thematic Analysis Of A Project-Based Internship, Robert Donavin Mccreary

Open Access Theses & Dissertations

In order to increase the number of students pursuing science-related careers, science educators and policymakers have advocated for improving student attitudes toward science (SAS) through inquiry-based instruction, such as project-based learning (PBL). While challenges exist in PBL, research suggests cogenerative dialogue (cogen) can ease the transition for students from traditional learning to PBL. In the present study, a secondary analysis was conducted to examine SAS growth trajectories from participants of the Work With A Scientist Program (WWASP) – a student-scientist internship which integrated cogen with PBL. Additionally, a thematic analysis was conducted to explore student attitudes toward cogen. The growth …

The Development Of The Adaptable Self-Disclosure Scale (Asds): A Multidimensional Approach To Disclosure Assessment, Brandon Mcintyre

All Dissertations

Understanding how individuals share or conceal parts of their identity has long been a topic of research with little consistency of measurement validation. The present study had three main goals: (1) define and conceptualize a multidimensional model of identity disclosure that can apply to any concealable identity, (2) generate a validated and adaptable scale for assessing any concealable identity, and (3) demonstrate the adaptability of this scale for a specific concealable identity. In Study 1, the proposed disclosure model was used to generate 72 items which were narrowed down using factor analysis to form the Adaptable Self-Disclosure Scale (ASDS). The …

Characterizing Human Random-Sequence Generation In Competitive And Non-Competitive Environments Using Lempel-Ziv Complexity, Alice Wong, Garance Merholz, Uri Maoz

Psychology Faculty Articles and Research

The human ability for random-sequence generation (RSG) is limited but improves in a competitive game environment with feedback. However, it remains unclear how random people can be during games and whether RSG during games can improve when explicitly informing people that they must be as random as possible to win the game. Nor is it known whether any such improvement in RSG transfers outside the game environment. To investigate this, we designed a pre/post intervention paradigm around a Rock-Paper-Scissors game followed by a questionnaire. During the game, we manipulated participants’ level of awareness of the computer’s strategy; they were either …
