Existence And Non-Existence Of Doubly Heavy Tetraquark Bound States, M. Pflaumer, Luka Leskovec, S. Meinel, M. Wagner

Physics Faculty Publications

In this work we investigate the existence of bound states for doubly heavy tetraquark systems Q¯Q¯′qq′ in a full lattice-QCD computation, where heavy bottom quarks are treated in the framework of non-relativistic QCD. We focus on three systems with quark content b¯b¯ud, b¯b¯us and b¯c¯ud. We show evidence for the existence of b¯b¯ud and b¯b¯us bound states, while no binding appears to be present for b¯c¯ud. For the bound four-quark states we also discuss the importance of various creation operators and give an estimate of the meson-meson and diquark-antidiquark percentages.

Updated Analysis Of An Unexpected Correlation Between Dark Matter And Galactic Ellipticity, D. M. Winters, Alexandre Deur, X. Zheng

Physics Faculty Publications

We investigate a correlation between the dark matter content of elliptical galaxies and their ellipticity ϵ that was initially reported in 2014. We use new determinations of dark matter and ellipticities that are posterior to that time. Our data set consists of 237 elliptical galaxies passing a strict set of criteria that selects a homogeneous sample of typical elliptical galaxies. We find a relation between the mass-to-light ratio and ellipticity ϵ that is well fitted by M/L = (14.1 ± 5.4)ϵ, which agrees with the result reported in 2014. Our analysis includes 135 galaxies that were not in …

Trajectories Of Relational Turbulence And Affectionate Communication Across The Post-Deployment Transition, Leanne K. Knobloch, Lynne M. Knobloch-Fedders, Jeremy B. Yorgason, Erin C. Wehrman, J. Kale Monk

Psychology Faculty Research and Publications

Affectionate communication may play a key role in how military couples navigate the transition from deployment to reintegration. Informed by relational turbulence theory, this study considered how the trajectory of relational turbulence experienced by military couples over time predicted their verbal and nonverbal expressions of affection. Online self-report data were gathered from 268 U.S. military couples across eight months beginning at homecoming. Relational turbulence increased over time and affectionate communication decreased over time. Also as predicted, the trajectory of increasing relational turbulence corresponded with greater declines in verbal and nonverbal expressions of affection. These results advance relational turbulence theory, illuminate …

Habit And Diabetes Self-Management In Adolescents With Type 1 Diabetes, C. Cummings, N. E. Benjamin, H. Y. Prabju, L. B. Cohen, B. J. Goddard, Astrida S. Kaugars, T. Humiston, A. H. Lansing

Psychology Faculty Research and Publications

Objective: The development of habit (i.e., behavioral automaticity, the extent to which a behavior is performed with decreased thresholds for time, attention [effort], conscious awareness, and goal dependence), for goal-directed health behaviors facilitates health behavior engagement in daily life. However, there is a paucity of research examining automaticity for Type 1 diabetes self-management in adolescence. This study examined if greater perceived automaticity for diabetes self-management was associated with increased daily self-management, decreased daily self-regulation failures in glucose checking, and more optimal daily glycemic levels in adolescents with Type 1 diabetes. Method: Adolescents aged 13–17 and diagnosed with Type 1 diabetes …

Interpersonal Violence And Mental Health Outcomes: Mediation By Self-Efficacy And Coping, Eunice Magalhaes, John H. Grych, Celia Ferreira, Carla Antunes, Ana Prioste, Ines Jongenelen

Psychology Faculty Research and Publications

There is a compelling need to explore the mechanisms linking violence to mental health. This study tested the mediating role of self-efficacy and coping in the association between victimization and mental health. Data were obtained from 422 adults (aged 18-77; M = 30.05; SD = 10.93). Self-efficacy and maladaptive coping strategies mediated the association between physical victimization and anxiety, and the association between psychological victimization and satisfaction with life anxiety and depression. Self-efficacy and adaptive coping also mediated the association between psychological victimization and satisfaction with life. This study provides important implications for research and practice.

Party Frequency, Party-Safety Strategies, And Sexual Victimization Among First-Year Female College Students, Ernest N. Jouriles, Alison Krauss, Kelli S. Sargent, Jamie Nguyen, Michele Cascardi, John H. Grych, Renee Mcdonald

Psychology Faculty Research and Publications

Objective: This study examined whether the use of party-safety strategies weakens the association between frequency of party attendance and sexual victimization among first-year female college students.

Participants: First-year female college students (n = 450) from three universities in the United States participated in this study.

Methods: Participants completed questionnaires on frequency of party attendance, use of party-safety strategies, and sexual victimization.

Results: Frequency of party attendance was positively associated with sexual victimization. This association was moderated by use of party-safety strategies: frequency of party attendance was unrelated to sexual victimization when students reported greater use of party-safety strategies. However, …

Covid-19 Stressors, Ethnic Discrimination, Covid-19 Fears, And Mental Health Among Latinx College Students, Lucas Torres

Psychology Faculty Research and Publications

This study examined the links between COVID-19 psychosocial stressors, ethnic discrimination, COVID-19 fears, and their combined effects on mental health outcomes among U.S.-based Latinx college students (N = 148; M_age = 20.68, SD = 2.53). Findings showed that sleep and eating disturbances, emotional distress, and work disruptions were linked with fear of contamination, fear of social distancing, and fear of pandemic impact. Further, ethnic discrimination was found to uniquely contribute to COVID-19 fears above and beyond COVID-19 psychosocial stressors. Finally, COVID-19 emotional distress and COVID fear of pandemic impact were significantly linked to anxiety and depression symptomatology. Recommendations …

Applying Lessons From Safety-Ii Proof Of Concept In Line Operational Safety Audit To Aviation Maintenance, David R. Zubowski

Journal of Aviation/Aerospace Education & Research

Maintenance safety culture is a topic that continues to arise. There is much information in many different literature sources that discusses measuring, analyzing, and scrutinizing data to determine if a safety culture exists in an organization and how to improve it. Currently, aviation maintenance personnel are surveyed for their opinions on how safe their culture is. However, this may not be an adequate reflection of the safety culture or help maintenance personnel conduct their jobs. Typically, they are operating in an environment that has a central determination of what safety culture is. Other programs in other fields have attempted a …

Plain Language Or Anything But?, Jennifer F. Drayton, Averil Coxhead

Journal of Aviation/Aerospace Education & Research

This paper focuses on what language needs to be used in emergencies by air traffic controllers based on an investigation of plain language definitions and descriptions in International Civil Aviation Organization (ICAO) publications and in the beliefs of nine air traffic controllers in the United Arab Emirates. The aim of the study is pedagogical, in that it is important to establish what language trainee air traffic controllers need to use during emergencies, but there is little in the way of course books or materials that can inform course development. Findings suggest there are contradictions in the ICAO documentation, and differences …

Journal of Aviation/Aerospace Education & Research

This study investigates eight viable United States major passenger airlines' outsourced maintenance impact on profitability between 1995 and 2019 by using panel data analysis. The results demonstrate that the percentage of airline outsourced maintenance and inhouse maintenance labor pay have no statistically significant impact on profitability. The researchers call for the further research with a larger sample, and more time periods to explore airlines' outsourced maintenance impact on profitability.

Investigation Of Pilots' Visual Entropy And Eye Fixations For Simulated Flights Consisted Of Multiple Take-Offs And Landings, Salem M. Naeeri, Ziho Kang, Ricardo Palma Fraga

Journal of Aviation/Aerospace Education & Research

Eye movement characteristics might provide insights on pilots' mental fatigue during prolonged flight. The visual entropy, eye fixation numbers, and eye fixation durations of ten novice pilots and ten expert pilots were analyzed for a four-hour simulated flight task consisting of four consecutive flight legs. Each flight leg lasted approximately one hour and contained five flight phases: takeoff, climb, cruise, descend, and landing. The pilots maneuvered the simulated B-52 aircraft following instrument flight rules (IFR) in a moderate-fidelity Microsoft Flight Simulator environment. Our results indicate that experts’ eye movement characteristics were significantly different from those of novices. In detail, novices' …

School Choice Factors Influencing U.S. Domestic And International Student Pilots’ Selections Of Vocational Flight Schools, Jingmin Jin

Journal of Aviation/Aerospace Education & Research

As international civil aviation activities resume from the COVID-19 pandemic, along with fleet growth and high retirement rates for senior pilots, there is a concern about the industry’s capability in supplying sufficient numbers of competent professional pilots. In order to advance the industry’s recruitment, it is necessary to determine effective approaches that may attract prospective student pilots to flight schools. This study investigated how school choice factors influenced U.S. domestic student pilots’ selections of vocational, non-collegiate flight schools in comparison to international student pilots. The study data were adopted from a 2019 survey research, which included 157 domestic and 44 …

An Analysis Of The Effect Of Self-Efficacy Of Female Students In Collegiate Flight Programs, Stefanie Horton, Mallory K. Casebolt

Journal of Aviation/Aerospace Education & Research

The purpose of this research was to examine the effect of self-efficacy of male and female students in collegiate flight programs to identify if a relationship exists between self-efficacy responses and gender representation in aviation. Self-efficacy, an element of social cognitive career theory’s (SCCT) behavioral factors, deals with an individual’s belief in his/her capacity to address a certain set of circumstances. No studies have been found addressing self-efficacy of students enrolled in collegiate aviation programs, specifically addressing differences between male and female students. The population for this study consisted of students enrolled in four-year collegiate aviation programs, as found through …

“You’Ll Never Really Be One Of Us”: Women’S Underrepresentation In The Aviation Workforce, Rebecca K. Lutte, Shannon M. Morrison

Journal of Aviation/Aerospace Education & Research

Women are underrepresented in many aviation occupations despite outreach and recruitment efforts from multiple organizations. Attracting women into aviation is a necessity not only to address workforce demand but also to achieve the benefits of a more diverse workforce to include enhanced profitability, safety, and innovation. To address the gender gap, the research presented here attempts to inform recruitment/retention strategies by identifying both the positive and negative factors that influence a woman’s decision to pursue a career in aviation and the decision to persist. Additionally, factors such as participation in youth outreach programs, role of mentors, influencers who support or …

Mandhar Smart Application For The Visual Pollution In Muhaisnah-2 Area – Dubai Uae, Hamda Mohamed Alharmoudi

Theses

People naturally love beauty, beautiful views, and a beautiful environment. Beauty is the human eye that makes him happy and brings pleasure to his heart. If sport feeds the body and science feeds the mind, then beauty feeds the soul and the mind, all the beauty around us feeds the brain that has a positive impact on human life, and the distortion that we encounter in our life has a negative impact on us. Therefore, visual pollution is defined as, everything that is inconsistent with the beauty of the environment that surrounds us which create a harmful change for the …

Intelligent Navigation Service Robot Working In A Flexible And Dynamic Environment, Said Abdallah

Theses

Numerous sensor fusion techniques have been reported in the literature for a number of robotics applications. These techniques involved the use of different sensors in different configurations. However, in the case of food driving, the possibility of the implementation has been overlooked. In restaurants and food delivery spots, enhancing the food transfer to the correct table is neatly required, without running into other robots or diners or toppling over. In this project, a particular algorithm module has been proposed and implemented to enhance the robot driving methodology and maximize robot functionality, accuracy, and the food transfer experience. The emphasis has …

Dynamic Modeling Of Inland Flooding And Storm Surge On Coastal Cities Under Climate Change Scenarios: Transportation Infrastructure Impacts In Norfolk, Virginia Usa As A Case Study, Yawen Shen, Navid Tahvildari, Mohamed M. Morsy, Chris Huxley, T. Donna Chen, Jonathan Lee Goodall

Civil & Environmental Engineering Faculty Publications

Low-lying coastal cities across the world are vulnerable to the combined impact of rainfall and storm tide. However, existing approaches lack the ability to model the combined effect of these flood mechanisms, especially under climate change and sea level rise (SLR). Thus, to increase flood resilience of coastal cities, modeling techniques to improve the understanding and prediction of the combined effect of these flood hazards are critical. To address this need, this study presents a modeling system for assessing the combined flood impact on coastal cities under selected future climate scenarios that leverages ocean modeling with land surface modeling capable …

Editorial: Coastal Flooding: Modeling, Monitoring, And Protection Systems, Valentina Prigiobbe, Clint Dawson, Yao Hu, Hatim O. Sharif, Navid Tahvildari

Civil & Environmental Engineering Faculty Publications

Coastal flooding has received significant attention in recent years due to future sea-level rise (SLR) projections and intensification of precipitation, which will exacerbate frequent flooding, coastal erosion, and eventually create permanently inundated low-elevation land. Coastal governments will be forced to implement measures to manage risk on the population and infrastructure and build protection systems to mitigate or adapt to the negative impacts of flooding. Research in this area is required to establish holistic frameworks for timely and accurate flooding forecast and design of protection systems.

The Effectiveness Of Teaching Life Skills Through Sport-Based Interventions For Youth At Risk, Mindy K. Mccarthy, Brandonn S. Harris, Katy Gregg

National Youth Advocacy & Resilience Journal

One resource for these youth involve sport-based interventions designed to enhance psychosocial wellbeing. Using a single-subject design, the current study examined the effectiveness of a life skills program through sport in a sample of strategically identified youth (Danish, 2002); two additional mental skill modules were also implemented. Participants included three male adolescents. Using basketball to implement the program, life skills included managing emotions, goal setting, relaxation, confidence, mental preparation, and seeking help from others. Participants …

The Relationship Between Principal Attrition And Academic Factors In Georgia’S High-Needs Rural Schools, Summer Pannell, Juliann Sergi Mcbrayer

National Youth Advocacy & Resilience Journal

The purpose of this study was to explore the relationship between principal attrition and academic factors in Georgia’s high-needs rural schools. The research shows that principals have a significant impact on student outcomes, and principal attrition is a disruptive factor in schools. The findings from this study indicate a negative correlation between principal turnover and every academic component of Georgia’s College and Career Readiness Index (CCRPI) at elementary, middle, and high schools in high-needs rural schools in Georgia. Implications for practice are the need to recruit and retain high-quality principals in Georgia’s high-needs rural schools and the development of purposeful, …

Changing My Language And Understanding: An Autoethnography Of My Dumb-Upness, Eric Hogan

National Youth Advocacy & Resilience Journal

Education, in its many forms, is an institution that mirrors the society around it, including its patterns of privilege and marginalization (Marx, et al., 2017). The purpose of this article is to provide a reflection of my experiences while working alongside four interns from an alternative school hired to work for an agricultural internship. I highlight my shifting perspectives through an autoethnography. Autoethnographic projects use selfhood, subjectivity, and personal experience (“auto”) to describe, interpret, and represent (“graphy”) beliefs, practices, and identities of a group or culture (“ethno”). (Adams and Herrmann 2020). After working with four interns, I was confronted with …

Bullying Prevention Essay And Art Competitions: Honoring School District Champions, Chasity D. Tompkins

National Youth Advocacy & Resilience Journal

Bullying is not a new concept. In fact, most of us can recall a time when we were bullied, someone else was bullied, or we bullied someone. While bullying can happen anywhere (including online through cyber-bullying), schools are often the center of research. Evaluations on school climate use bullying to help understand relationships. Prevention methods put the teacher or school staff in the driver seat, but these adults may not feel a connection to the work. Our school district created the Bullying Prevention Essay Contest to honor school district champions through literacy. Middle and high school students wrote about adults …
