Title: TOWARD A MODEL OF TEAM DECISION MAKING UNDER STRESS.
Creator: Marshall, Alyssa, Salas, Eduardo, University of Central Florida
Abstract / Description: Today's organizations are increasingly relying on teams, rather than individuals, to complete tasks in the workplace. For some teams, these tasks require them to make high stakes decisions under stressful conditions. In military, medical, and emergency response fields, for example, workers are regularly asked to make decisions under high time pressure, uncertainty, and risk. The purpose of this study is to summarize previous team decision-making perspectives and create a model for team...
Show moreToday's organizations are increasingly relying on teams, rather than individuals, to complete tasks in the workplace. For some teams, these tasks require them to make high stakes decisions under stressful conditions. In military, medical, and emergency response fields, for example, workers are regularly asked to make decisions under high time pressure, uncertainty, and risk. The purpose of this study is to summarize previous team decision-making perspectives and create a model for team decision-making under stress. A literature review was conducted to examine the current state of team decision-making research. Several existing models of the team decision-making process were identified, representing multiple decision-making perspectives. Using this information, four primary characteristics of the team decision making process were identified. Team decision making appears to be multi-level, multi-phasic, dynamic, and cyclical process. An additional search examined the effects of stress on performance. Using this information and the characteristics outlined from the team decision making literature, a model was designed to describe the effects of stress on team decision making. This model offers several propositions regarding the effects of stress on specific cognitive and team processes and their relationship team decision making. This study provides the theoretical basis for an empirical investigation of the relationship between stress and team decision making. This line of research has the potential to lead to practical solutions that may improve outcomes for workers in high stress occupations.

Title: TOWARD A THEORY OF PRACTICAL DRIFT IN TEAMS.
Creator: Bisbey, Tiffany, Salas, Eduardo, University of Central Florida
Abstract / Description: Practical drift is defined as the unintentional adaptation of routine behaviors from written procedure. The occurrence of practical drift can result in catastrophic disaster in high-reliability organizations (e.g. the military, emergency medicine, space exploration). Given the lack of empirical research on practical drift, this research sought to develop a better understanding by investigating ways to assess and stop the process in high-reliability organizations.

Show morePractical drift is defined as the unintentional adaptation of routine behaviors from written procedure. The occurrence of practical drift can result in catastrophic disaster in high-reliability organizations (e.g. the military, emergency medicine, space exploration). Given the lack of empirical research on practical drift, this research sought to develop a better understanding by investigating ways to assess and stop the process in high-reliability organizations. An introductory literature review was conducted to investigate the variables that play a role in the occurrence of practical drift in teams. Research was guided by the input-throughput-output model of team adaptation posed by Burke, Stagl, Salas, Pierce, and Kendall (2006). It demonstrates relationships supported by the results of the literature review and the Burke and colleagues (2006) model denoting potential indicators of practical drift in teams. Research centralized on the core processes and emergent states of the adaptive cycle; namely, shared mental models, team situation awareness, and coordination. The resulting model shows the relationship of procedure—practice coupling demands misfit and maladaptive violations of procedure being mediated by shared mental models, team situation awareness, and coordination. Shared mental models also lead to team situation awareness, and both depict a mutual, positive relationship with coordination. The cycle restarts when an error caused by maladaptive violations of procedure creates a greater misfit between procedural demands and practical demands. This movement toward a theory of practical drift in teams provides a conceptual framework and testable propositions for future research to build from, giving practical avenues to predict and prevent accidents resulting from drift in high-reliability organizations. Suggestions for future research are also discussed, including possible directions to explore. By examining the relationships reflected in the new model, steps can be taken to counteract organizational failures in the process of practical drift in teams.

Title: TOWARD INCREASING PERFORMANCE AND EFFICIENCY IN GAS TURBINES FOR POWER GENERATION AND AERO-PROPULSION: UNSTEADY SIMULATION OF ANGLED DISCRETE-INJECTION COOLANT IN A HOT GAS PATH CROSSFLOW.
Creator: Johnson, Perry, Kapat, Jayanta, University of Central Florida
Abstract / Description: This thesis describes the numerical predictions of turbine film cooling interactions using Large Eddy Simulations. In most engineering industrial applications, the Reynolds-Averaged Navier-Stokes equations, usually paired with two-equation models such as k-[epsilon] or k-[omega], are utilized as an inexpensive method for modeling complex turbulent flows.

Show moreThis thesis describes the numerical predictions of turbine film cooling interactions using Large Eddy Simulations. In most engineering industrial applications, the Reynolds-Averaged Navier-Stokes equations, usually paired with two-equation models such as k-[epsilon] or k-[omega], are utilized as an inexpensive method for modeling complex turbulent flows. By resolving the larger, more influential scale of turbulent eddies, the Large Eddy Simulation has been shown to yield a significant increase in accuracy over traditional two-equation RANS models for many engineering flows. In addition, Large Eddy Simulations provide insight into the unsteady characteristics and coherent vortex structures of turbulent flows. Discrete hole film cooling is a jet-in-cross-flow phenomenon, which is known to produce complex turbulent interactions and vortex structures. For this reason, the present study investigates the influence of these jet-crossflow interactions in a time-resolved unsteady simulation. Because of the broad spectrum of length scales present in moderate and high Reynolds number flows, such as the present topic, the high computational cost of Direct Numerical Simulation was excluded from possibility.

Title: TOWARDS THE FINITE: A CASE AGAINST INFINITY IN JORGE LUIS BORGES.
Creator: SANTIS, ESTEBAN, Rodríguez Milanés, Cecilia, University of Central Florida
Abstract / Description: The role of infinity as an antagonist in Jorge Luis Borges's oeuvre is undeniable. His stories in El jardín de senderos que se bifurcan (1941), Ficciones (1944), and El Aleph (1949) exhibit Borges's tendency to evoke dreams, labyrinths, mirrors, and libraries as both conduits for infinity and sources of conflict.

Show moreThe role of infinity as an antagonist in Jorge Luis Borges's oeuvre is undeniable. His stories in El jardín de senderos que se bifurcan (1941), Ficciones (1944), and El Aleph (1949) exhibit Borges's tendency to evoke dreams, labyrinths, mirrors, and libraries as both conduits for infinity and sources of conflict. Oftentimes, Borges's characters experience discomfort upon encountering the limitations of secular temporal succession. This discomfort is rooted in Borges's pessimism about the subject which is explored in Borges's most comprehensive essay on the issue of time: "A New Refutation of Time." Consequently, this thesis considers Borges's attitude towards the issue of time as postulated in "A New Refutation of Time" and exhibited in his early fiction, continues to acknowledge infinity as a fundamental conflict in Borges's work, and proceeds to search for a solution to this conflict.The analysis in this thesis relies heavily on a comparative study of the themes and symbols in Borges's fiction in order to establish a pattern wherein infinity is portrayed negatively. More importantly, the use of interviews, biographies, and Borges's own fiction, facilitates the construction of cohesive conception of time in his work. Subsequently, this study looks to establish a solution to the problem of infinity and establish a new pattern wherein there is a positive resolution to the narrative. Ultimately, the goal of this thesis is to acknowledge the problem of infinity in Borges's work and then propose a way to escape it.

Show moreTracking ability of leveraged and inverse exchange traded funds can be very important to investors looking for a dependable return. If the investor wants to put their money on a certain index they feel strongly about, they expect their investment vehicle to track that return appropriately. Over the years, we have seen tremendous growth in the exchange traded fund industry. In 2006, leveraged and inverse funds were introduced to the market, allowing investors to take leveraged and directional trades on indices. These investment vehicles can be traded as easily as any stock, and therefore need some attention. Since any novice investor can access and trade these funds, they need to be aware of the risks they are taking. In this study, I test whether the ProShares S&P tracking leveraged and inverse exchange traded funds track their appropriate index multiple as promised. I did this by running regressions on each fund against the appropriate multiple of their underlying indices. I did this for funds of different market capitalization, for different holding periods, and with different amounts of leverage, to compare how these funds track in different conditions. I found that the large cap funds tend to track the best, with the small cap funds tracking the worst. I also find that tracking error tends to increase with longer holding periods. I find that the distribution of excess returns becomes less normal over longer holding periods, and begins to flatten out and widen. There does not seem to be a concrete conclusion as to whether or not the amount of leverage affects the tracking ability of the funds. I end up with mixed results when comparing amounts of leverage by model fit and by tracking error. Direction also does not seem to play any role in the tracking ability of these funds.

The purpose of this study is to critically review the empirical research of trauma-focused and trauma-informed trainings and treatment models for children who have suffered some form of trauma and whose caregiver is included in the treatment. The outcomes of trauma-focused models will be examined in terms of its purpose, intervention, facilitation, adaptability and modification. Implications for further research and application are drawn.

Show moreGrave markers represent a significant amount of highly important information related to the cultural patterns of a society, as well as how these patterns have changed over time. Although, cemetery studies are popular in other regions of the United States, few studies regarding grave marker attributes have been conducted in Florida. The purpose of this research was to analyze and interpret temporal and demographic changes in grave marker attributes in Greenwood Cemetery in Orlando, Florida. Another aspect of this research focused on the possible correlation between the age and inferred sex of the deceased individual in relation to the type of epitaph and iconography chosen to represent them in their mortuary context. Data was collected from 925 headstones within Greenwood Cemetery; these headstones further represent 1,102 individuals. Attributes analyzed include marker material, marker type, iconographic images, epitaph, memorial photographs, footstones and curbs. These attributes will be analyzed and compared to trends noted within a similar study conducted by Meyers and Schultz (2016), to allow for better interpretation of trends in grave marker attributes across a range of Florida cemeteries. Results indicate multiple trends. The popularity of marble headstones decreased greatly from 51% in Pre-1900 to only 8% from 2000 to 2017. Furthermore, the prevalence of epitaph and iconography categories vary greatly on both a temporal and demographic basis. Male infants are more likely than any other demographic group to be represented by a genealogical epitaph, at 41% representation. Ultimately, these trends illustrate important aspects of cultural changes related to mortuary practice and individual mortuary contexts within Orlando, Florida.

Show moreThe purpose of this study was to examine the motivation of individuals to use Truly Accomplished (TA) as a fitness intervention, with or without a social support component. All participants utilized the TA Software as a fitness intervention and received weekly feedback on their progress. Thirty participants were randomly assigned to either participate in the regular TA process or a modified TA process with the addition of a social support component in the form of a social media group. Participants in the modified condition posted weekly to a Facebook group page about successes and obstacles they faced and gave feedback to their peers. It was hypothesized that participants, regardless of condition, would show fitness gains in the 6-week study. Also, with the added social support component to TA, participants were expected to have higher levels of self-determination in relation to the three psychological needs (i.e. autonomy, relatedness, and competence) and higher levels of perceived social support. A between-subjects deign was used to measure overall effectiveness, changes in fitness performance (plank, push-ups, wall-sit, step-test) and body composition (BMI, percent body fat), perceived social support, levels of psychological needs satisfaction as it relates to the three basic needs (autonomy, competence, and relatedness), and satisfaction with TA. No significant differences were found between conditions for satisfaction with TA, levels of perceived social support, or levels of psychological needs satisfaction post-intervention. However, a significant increase was found regardless of condition in terms of autonomy and guidance. A significant increase was shown in both the plank and modified push-up post-intervention measure, regardless of condition. Finally, the condition with the added social support had a significantly higher overall effectiveness gain than the condition with no added social support. The practical and theoretical implications of the results are discussed.

Show moreThe current study examined Truly Accomplished (TA), an intervention designed to help individuals develop personalized systems to measure and improve behavior by utilizing well-established principles and research on motivation, participation and feedback. This study focused on participation during Success Map development (an integral step in the TA process) and the impact of using experts to develop Success Maps in the TA system. Using the context of fitness, 40 female participants were randomly assigned to either complete the regular TA process, developing their own Success Maps, or the modified TA process, using expert-developed Success Maps. A repeated-measures design with one between-subjects independent variable was used to measure overall effectiveness scores, changes in fitness performance (plank, wall-sit, push-ups, curl-ups) and body composition (BMI, percent body fat), attitudes of system development, satisfaction with TA and satisfaction with life. Additionally, the similarities between expert and self-developed Success Maps were compared. Across all participants, large gains in effectiveness were found, including significant increases in all measurers of fitness performance; however, attitudes were poorer when Success Maps were developed by experts. Moreover, there were differences between expert and self-developed Success Maps. Results support TA as an effective intervention for positive behavior change. The practical and theoretical implications of the differences found between conditions are discussed.

Show moreSince the cognitive revolution during the last century the mind has been conceived of as being computer-like. Like a computer, the brain was assumed to be a physical structure (hardware) upon which a computational mind (software) was built. The mind was seen as a collection of independent programs which each have their own specific tasks, or modules. These modules took sensory input "data" and transduced it into language-like representations which were used in mental computations. Recently, a new conception of the mind has developed, grounded cognition. According to this model, sensory stimulus is saved in the original format in which it was received and recalled using association mechanisms. Rather than representations being language-like they are instead multimodal. The manipulation of these multimodal representations requires processing distributed throughout the brain. A new holistic model for mental architecture has developed in which the concerted activity of the brain's modal systems produces functional systems which are intimately codependent with one another. The purpose of this thesis is to explore both the modular and multimodal theories of mental architecture. Each will be described in detail along with their supporting paradigms, cognitivism and grounded cognition. After my expositions I will offer support for my own position regarding these two theories before suggesting avenues for future research.

Show moreThe history of Latin America and the Caribbean was irreversibly altered by the arrival of the conquistadors, destruction of native civilizations and implementation of colonialism for hundreds of years. However, Spain also introduced the high culture of the baroque to Latin America and the Caribbean, which mixed with the cultures of native and African peoples, creating new, distinct forms of literary expression. Subsequent post-colonial cultural movements attempted to explore and reaffirm the variety of cultures that shaped both regions, including the movement of Afrocubanismo in Cuba, which occurred from 1910-1940. Afrocubanismo was a movement intended to incorporate African folklore and music into traditional modes of art. While many authors and artists were instrumental to Afrocubanismo, Nicol�s Guill�n is considered to be the most influential author of the movement, due to his new and inventive style of poetry that incorporated both Spanish and African influences. This study will demonstrate how Guill�n�s use of traditional poetic forms, the son and portrayal of everyday Afro-Cuban life reveal his vision for a post-colonial, transcultured Cuban society, rather than a Cuba subject to colonialism and acculturation.

Show moreThe foreign policy of the United States of America toward the Democratic People's Republic of Korea (DPRK), commonly known as North Korea, has an important role in maintaining the peace, stability, and security of Eastern Asia. From the partition of the Korean peninsula following World War II to the country's development of nuclear weapons, the foreign policy of the U.S. had to evolve based on the circumstances in North Korea. The United States, along with China, Japan, Russia, and South Korea, have key roles surrounding the discussions with North Korea. The thesis focuses solely on the presidential administrations of Harry S. Truman, Dwight D. Eisenhower, Lyndon B. Johnson, Richard Nixon, Bill Clinton, George W. Bush, and Barack Obama; these men had the greatest impact on U.S. foreign policy with North Korea. The thesis takes a qualitative approach of research by using primarily government documents, historical records from presidential administrations, articles from foreign policy journals, and books by foreign policy experts. Throughout the research, two common themes of U.S. relations toward North Korea emerge, uncertainty and defiance. North Korea's secretive regime makes it difficult for U.S. presidential administrations to determine the intentions of North Korea's actions. Furthermore, the uncertainty often leads to defiant and aggressive actions by North Korea. From the USS Pueblo crisis to the bombing of Yeonpyeong Island, presidential administrations had to walk a fine line of responding with aggression, negotiations, or appeasement. The thesis examines not only the options and implementations of each presidential administration, but also looks toward possible solutions for maintaining peace and stability in Eastern Asia by improving relations with North Korea.

Also, smoking harms not only those whom choose to smoke but non-smokers in the area are affected by even low levels of cigarette smoke. Thus, cigarette smoking has become a public health concern. Around the globe, countries are passing smoke-free laws in public areas such as businesses, restaurants, and bars. In the United States, many universities have enacted smoke-free campus policies to ensure the health of all their students in all places on campus. The purpose of this research is to identify the support or opposition for a smoke-free campus policy at the University of Central Florida by UCF students. A survey was distributed to undergraduate students at UCF which asks whether they would support such a policy along with characterizing questions about their smoking habits, lifestyle, history, and opinion. The analysis of the data shows that the majority of UCF student would support a smoke-free campus policy.

Show moreStatistics is a course that is required for a majority of undergraduate college students in a wide variety of majors. It is not just required for Statistics or Mathematics majors, but also for those undergraduate college students majoring in Biology, Engineering, Sociology, and countless other majors. It can often be seen as a daunting course, especially for those who feel that mathematics is not their strongest subject. Students begin to dislike the course before even starting and this can carry on throughout the entirety of the course. This thesis will focus primarily on students' perceptions and attitudes toward their statistics courses rather than their performance. Many courses are taught a specific way that is conducive to all learning styles, which may lead to the students not enjoying or understanding their statistics course. The students' learning style may also be correlated to their attitude and perception of statistics. The goal of this thesis is to better understand the college students in order to adapt the current methods so that student can enjoy the course, appreciate the knowledge they learn and its impact on their future career paths.

Show moreIntra-vessel thrombosis leads to serious problems in patient health. Coagulation can constrict blood flow and induce myocardial infarction or stroke. Hemodynamic factors in blood flow promote and inhibit the coagulation cascade. Mechanically, high shear stress has been shown to promote platelet activation while laminar flow maintains plasma layer separation of platelets and endothelial cells, preventing coagulation. These relationships are studied experimentally, however, physical properties of thrombi, such as density and viscosity, are lacking in data, preventing a comprehensive simulation of thrombus interaction. This study incorporates experimental findings from literature to compile a characteristic mechanical property data set for use in thrombosis simulation. The focus of this study's simulation explored how thrombi interact between other thrombi and vessel walls via Volume of Fluid method. The ability to predict thrombosis under specific hemodynamic conditions was also a feature of the data collection. Using patient specific vessel geometry, the findings in this study can be applied to simulate thrombosis scenarios. The possible applications of such a simulation include a more precise method for estimation of patient myocardial infarction or stroke risk and a possible analysis of vessel geometry modification under surgery.

Title: UNDERSTANDING GENDER IDENTITY AMONG WOMEN COSPLAYERS OF THE GOTHAM CITY SIRENS.
Creator: Morrison, Amber, Mishtal, Joanna, University of Central Florida
Abstract / Description: As popular culture has an increasing presence in America, so do its various sub-cultures. One of such sub-cultures is the world of comic book fans known as cosplayers. Cosplayers dress-up and emulate characters at comic book conventions throughout the United States and the worldï¿½a practice known as cosplay, also described as costume-play. Despite the growing popularity of cosplay, little is known about this population. In this research, I set out to answer the following research question:...
Show moreAs popular culture has an increasing presence in America, so do its various sub-cultures. One of such sub-cultures is the world of comic book fans known as cosplayers. Cosplayers dress-up and emulate characters at comic book conventions throughout the United States and the worldï¿½a practice known as cosplay, also described as costume-play. Despite the growing popularity of cosplay, little is known about this population. In this research, I set out to answer the following research question: why are women choosing to dress-up and embody these characters (the Gotham City Sirens) when they are often viewed as oversexualized. In order to answer my research question, I focused on women who chose to cosplay characters from the Gotham City Sirens - Catwoman, Harley Quinn, and Poison Ivy - who are frequently depicted in "glamorized" or hypersexualized illustrations. My data collection included participant observation, literature review, and semi-structured interviews. Recruiting participants from local Central Florida comic book conventions, I conducted 19 in-depth semi-structured interviews with the women cosplayers about their perspectives on the characters and their cosplays. My findings derived from the analysis of the interview narratives identified three emerging dominant themes - sexuality, body image, and personal identity. Based on this research, there is a concluding realization that empowerment and self-reflection are prevalent in women cosplayers. These are important findings because they are essential to the understanding of how gender identity is perceived in cosplay. When cosplayers connect with their characters on a personal level, often empowerment and self-reflection are the outcomes; due to the connection they foster with the character for the sake of performance.

Title: UNDERSTANDING NEWS MEDIA VIEWING AND SELECTION PATTERNS: FOMO AND USER CONSUMPTION OF NEWS CONTENT ON SOCIAL MEDIA INTERFACES.
Creator: Christopher, Nicolette D, Bagley, George, Armato, Michael, University of Central Florida
Abstract / Description: The current study employs a regional sample in order to investigate the phenomenon of fear-of-missing-out (FoMO), the awareness associated with the fear that other individuals are having a more pleasurable experience that one is not a part of. The current study uniquely examines the role that FoMO plays in viewing patterns associated with news content on social media interfaces. The 10-item scale created by Przybylski, Myrayama, DeHaan, and Gladwell in 2013 was used as a basis to discover the...

The current study uniquely examines the role that FoMO plays in viewing patterns associated with news content on social media interfaces. The 10-item scale created by Przybylski, Myrayama, DeHaan, and Gladwell in 2013 was used as a basis to discover the degree of FoMO participants experience while online, while other questions of the survey serve to collect data about participants sociodemographic's, engagement with soft and hard news content, and overall social media usage. (Przybylski, Myrayama, DeHaan, Gladwell 2013). The objective is to demonstrate the influential effects that FoMO poses on media consumer viewing patterns and behaviors.

Show moreBackground: There is limited research on the healthcare experience of Deferred Action for Childhood Arrivals (DACA) recipients both before and after enrollment in the program. DACA is a program designed to defer deportation to children and young adults in the United States for up to 2 years. The goal of this qualitative study is to explore the lived experiences of DACA students with regards to access to healthcare and perceptions of treatment. Method: This study is qualitative and uses a phenomenological approach. DACA Recipients (N = 5) were recruited from the UCF student population and 1:1 interviews were conducted. Interviews were transcribed and manually coded. Results: Thematic analysis revealed the following three themes (1) Meeting Needs (2) It Takes a Village and (3) Documentation�� Over Insurance Conclusion: The fundamental structure of the findings shows the struggles of receiving healthcare as an undocumented immigrant, and the limitations of DACA as a solution. Health insurance is a more prominent and impactful factor than documentation status in the quality and quantity of healthcare access. The healthcare experience ranges from volunteer clinics to local pharmacies. Although, if DACA recipients have insurance, their healthcare experience is more consistent, regardless of documentation. Their day to day lives is composed of meeting basic needs, receiving only necessary doctor's visits as a child, and being prepared for all circumstances in terms of future citizenship.
