Show moreIn the health care industry, there are strategies to remove inefficiencies from the health delivery process called efficiency strategies. This dissertation proposed a simulation model to evaluate the impact of the efficiency strategies on a primary care clinic with unscheduled "walk-in" patient visits. The simulation model captures the complex characteristics of the Orlando Veteran's Affairs Medical Center (VAMC) primary care clinic. This clinic system includes different types of patients, patient paths, and multiple resources that serve them. Added to the problem complexity is the presence of patient no-shows characteristics and unscheduled patient arrivals, a problem which has been until recently, largely neglected. The main objectives of this research were to develop a model that captures the complexities of the Orlando VAMC, evaluate alternative scenarios to work in unscheduled patient visits, and examine the impact of patient flow, appointment scheduling, and capacity management decisions on the performance of the primary care clinic system. The main results show that only a joint policy of appointment scheduling rules and patient flow decisions has a significant impact on the wait time of scheduled patients. It is recommended that in the future the clinic addresses the problem of serving additional walk-in patients from an integrated scheduling and patient flow viewpoint.

Show moreDeath is something everyone will eventually encounter, yet American society has a tendency to avoid or deny death in everyday life and language. Death makes people uncomfortable, and many view it as a topic too complex for children to understand. Children, however, witness big and little deaths in their lives: of pets, relatives, plants, and favorite fairy tale characters. When a child experiences a death, he or she may have questions for parents or other trusted adults which our current avoidance-geared society does not prepare adults for.Children exist in a specific cultural context, and learn rules and expectations of society from an early age. How society views a subject like death will influence how it is talked about, experienced, and learned. Parents and families serve as the primary means of socialization for young children and hold a position of expertise within the parent-child dynamic. Both socio-cultural and personal beliefs about death will influence how a parent approaches death education with his or her child.Through examination of the sensemaking and sensegiving accounts of parent participants, this study sought to understand what the process is like for parents who are discussing the subject of death with their children, what goals and concerns parents have, what information a parent privileges as important within the social and historical context of the conversation, and what resources he or she accesses, if any, to assist with communication. By framing the participants' experiences as (")making sense(") of a social environment after an interruption, this study was able to investigate the processes of sensemaking and sensegiving in an interpersonal context between parent and child, the roles of Weick's (1995) characteristics of sensemaking, implicit and explicit messages relayed to children about death, and the influence of social scripts on both processes.Twelve semi-structured, in-depth interviews were conducted to gather accounts in context of parents who had previously discussed death with their children. Interviews were analyzed based on a modified constructivist grounded theory approach (Charmaz, 2006). The study was designed to remain as close to the relayed experience of the participants as possible with hope that information from the participants' experiences will be useful for both academics and parents as a future resource for preparing for parent-child communication about death.

Show moreThe lived experiences of previously infertile mothers in the early postpartum period have not been previously studied. The purpose of the research was to explore the experiences of previously infertile mothers during their early postpartum period.Colaizzi's (1978) approach to descriptive phenomenological inquiry was used to analyze the interview data obtained from twelve first-time, previously infertile mothers. These new mothers, aged 27 to 43 years, were interviewed twice. The first interview focused on eliciting descriptions of new motherhood in the early postpartum period after overcoming infertility. The second interview validated the interpretations from the first interview and provided additional information and reflection. Two main themes emerged that described the early postpartum experience of first-time, previously infertile mothers: 1) Lingering Identity as Infertile; and 2) Gratitude for the Gift of Motherhood. Participants reported that their lingering identity as infertile and immense gratitude for the gift of motherhood propelled them to establish unrealistic expectations to be the perfect mother. When they were unable to live up to being the perfect mother, they censored their feelings of inadequacy, guilt, and shame. Findings from this study sensitize healthcare providers to the difficulties faced by previously infertile women during their transition to motherhood.

The proposed instrument is SHORE (Station High-Sensitivity Ocean Research Experiment), a multi-band optical spectrometer with 15 m pixel resolution. The analysis investigates the contribution of the error effects to the quality of data collected by the instrument. The analysis begins with the discussion of the coordinate systems involved and then conversion from the target coordinate system to the instrument coordinate system. Next the geometry of remote observations from the Space Station is investigated including the effects of the instrument location in Space Station and the effects of the line of sight to the target. The disturbance and error environment on Space Station is discussed covering factors contributing to drift and jitter, accuracy of pointing data and target and instrument accuracies. Finally, there is a brief discussion of image processing to address any post error correction options.

Show moreThis study investigates whether the learning strategy of Peer Presentations may positively influence an English Language Learner's (ELL's) relationship with peers, and personal perspectives with pertinence to the sciences, public discourse, and their institution. Data collection in-struments included a developed pre- and post-sociometric survey to quantitate each classroom's social status, and a pre- and post-qualitative oral interview to acquire individual perceptions concerning enjoyment and contentment of academic topics. Three ELLs from two learning environments participated with the eight day intervention, comprising of 45 minute instructive sessions to become proficient with demonstrating an arrangement of invigorating yet harmless scientific experiments. After the Peer Presentation, analysis of pre- and post-sociometric results demonstrated an overall increase of more intimate friendships. Examination of the ELLs' oral interview responses indicated growth of enjoyment regarding their institution and public discourse. Overall recommendations and suggestions of utilizing Peer Presentations are discussed for those involved with educating students.

Show moreEvidence-based educational policymaking has become a global phenomenon (Wiseman, 2010). According to the Institute of Education Sciences, evidence-based education is "an integration of the professional wisdom and the best available empirical evidence on making decision about how to deliver instructions" (IES, US Department of Education, 2012). This suggests that best practice requires teachers to ensure that instructional strategies and programs implemented in their classroom have been studied in scientific experiments to determine their effectiveness. The general public, as well as practicing teachers, holds an assumption that educators have knowledge as to what is evidence-based education. However, this is not always the case. The objective of this these include: to document how pre-service teachers access research findings and what types of findings they use in their practice, to identify the purposes of its utilization, to identify the factors that influence research utilization, and to ensure the accessibility of the findings of this study. The population for this study will be pre-service teachers at a large public higher education institution and one state college. In order to meet these objectives I conducted a survey, a pre-service teacher focus group, and an interview with faculty. Research findings will impact pre-service teacher preparation programs and increase our understanding of the link between the researchers and educators

Show moreThe deficit narrative about marginalized students of color attributes their failure in school to some nature of innate cognitive deficiency, cultural, social, and familial dysfunctions among other schools of thoughts. The purpose of this grounded theory study is to provide a rich description about this phenomenon and to propose theoretical pedagogical adjustments in the classroom as it relates to educating students of color. The study applies Charmaz (2014) Constructivist approach to grounded theory methods to examine the following research questions: (RQ1) How do teachers' narratives about students of color depict their teaching experiences and (RQ2) How do teachers' narratives about students of color inform students learning? Two overarching themes emerged in this study: practicing color blindness impacts cultural responsiveness while perpetuate deficit thinking, and understanding cultural background stimulates sensitivity when designing curriculum for students of color. The findings of this research demonstrate teachers' deficit thinking depicts their pedagogical practices and informs students learning. The research has both practical and theoretical implications for dispelling the deficit thinking regarding students of color.

Show moreBridge networks are expensive and complex infrastructures and are essential components of today's transportation systems. Despite the advancement in computer aided modeling and increasing the computational power which is increasing the accessibility for developing the fragility curves of bridges, the complexity of the problem and uncertainties involved in fragility analysis of the bridge structures in addition to difficulties in validating the results obtained from the analysis requires precaution in utilization of the results as a decision making tool. The main focus of this research is to address, study and treatment of uncertainties incorporated in various steps of performance based assessments (PBA) of the bridge structures. In this research the uncertainties is divided into three main categories. First, the uncertainties that come from ground motions time and frequency content alteration because of scarcity of the recorded ground motions in the database. Second, uncertainties associated in the modeling and simulation procedure of PBA, and third uncertainties originated from simplistic approach and methods utilized in the conventional procedure of PBA of the structures. Legitimacy of the scaling of ground motions is studied using the response of several simple nonlinear systems to amplitude scaled ground motions suites. Bias in the response obtained compared to unscaled records for both as recorded and synthetic ground motions.Results from this section of the research show the amount of the bias is considerable and can significantly affect the outcome of PBA. The origin of the bias is investigated and consequently a new metric is proposed to predict the bias induced by ground motion scaling without nonlinear analysis. Results demonstrate that utilizing the predictor as a scaling parameter can significantly reduce the bias for various nonlinear structures. Therefore utilizing the new metric as the intensity measuring parameter of the ground motions is recommended in PBA. To address the uncertainties associated in the modeling and simulation, MSSS concrete girder bridge class were selected due to the frequency of the construction in USCS region and lack of seismic detailing. A large scale parameters screening study is performed using Placket-Burman experimental design that considers a more complete group of parameters to decrease the computational expense of probabilistic study of the structure's seismic response. Fragility analysis for MSSS bridge is performed and the effect of removing the lesser important parameters the probabilistic demand model was investigated. This study reveals parameters reduction based on screening study techniques can be utilized to increase efficiency in fragility analysis procedure without compromising the accuracy of the outcome. The results from this study also provides more direct information on parameter reduction for PBA as well as provide insight into where future investments into higher fidelity finite element and constitutive models should be targeted. Conventional simplistic PBA approach does not account for the fundamental correlation between demand and capacity models. A more comprehensive PBA approach is presented and fragility analysis is performed with implementation of a new formulation in the component fragility analysis for MSSS bridge class and the outcome is compared with the one from conventional procedure. The results shows the correlation between demand and capacity affects the outcome of PBA and the fragility functions variation is not negligible. Therefore using the presented approach is necessary when accuracy is needed.

Show moreThe U.S. shortage of qualified nursing teachers and researchers is affecting national health care outcomes. Methods such as fast-tracking Baccalaureate nurses into graduate programs and embedding leadership development early into nursing curricula have been proposed to address faculty and research shortages. Early interest in nursing research careers increases likelihood of enrollment in graduate education. One way undergraduate nursing students may develop an interest in research careers is through a mentored apprenticeship with research-active faculty. In this thesis, the author uses an autoethnography methodology to examine the benefits that a mentored research apprenticeship model brought to her undergraduate experience. Her experience incorporated a variety of roles in an adolescent intervention program with Dr. Anne Norris (PI) at the University of Central Florida College of Nursing. Several themes about the experience were defined in the results. Early research exposure that socializes a student to the nursing research world may provide a means for addressing the nursing faculty shortage. This socialization can generate interest in a research career and promote undergraduate students with the essential tools and insights needed to pursue this career pathway. However, findings from this study suggest a student-mentor relationship early in the undergraduate education experience is essential.

Show moreThere is a large increase in the surge of data over Internet due to the increasing demand on multimedia content. It is estimated that 80% of Internet traffic will be video by 2022, according to a recent study. At the same time, IoT devices on Internet will double the human population. While infrastructure standards on IoT are still nonexistent, enterprise solutions tend to encourage cloud-based solutions, causing an additional surge of data over the Internet. This study proposes solutions to bring video traffic and IoT computation back to the edges of the network, so that costly Internet infrastructure upgrades are not necessary. An efficient way to prevent the Internet surge over the network for IoT is to push the application specific computation to the edge of the network, close to where the data is generated, so that large data can be eliminated before being delivered to the cloud. In this study, an event query language and processing environment is provided to process events from various devices. The query processing environment brings the application developers, sensor infrastructure providers and end users together. It uses boolean events as the streaming and processing units. This addresses the device heterogeneity and pushes the data-intense tasks to the edge of network.The second focus of the study is Video-on-Demand applications. A characteristic of VoD traffic is its high redundancy. Due to the demand on popular content, the same video traffic flows through Internet Service Provider's network as overlapping but separate streams. In previous studies on redundancy elimination, overlapping streams are merged into each other in link-level by receiving the packet only for the first stream, and re-using it for the subsequent duplicated streams. In this study, we significantly improve these techniques by introducing a merger-aware routing method.Our final focus is increasing utilization of Content Delivery Network (CDN) servers on the edge of network to reduce the long-distance traffic. The proposed system uses Software Defined Networks (SDN) to route adaptive video streaming clients to the best available CDN servers in terms of network availability. While performing the network assistance, the system does not reveal the video request information to the network provider, thus enabling privacy protection for encrypted streams. The request routing is performed in segment level for adaptive streaming. This enables to re-route the client to the best available CDN without an interruption if network conditions change during the stream.

Show moreThis study explores the lived experiences of older students who work and have family responsibilities while attending an undergraduate program full-time. Research indicates that this segment of the student population is the only one that is growing today and is projected to grow in the future; this also is the largest the group of students thatdoes not finish their studies in spite of the many services aimed at supporting students' academic success.This study critically investigated the category of the nontraditional student and reviewed the literature about students' college experiences, including the limitations of its theoretical assumptions to describe and explain the nature of the college journey of olderstudents with substantive life experiences. From the notion that learning is lifelong and holistic (Jarvis, 2006), this study combined a student-centered approach with a hermeneutic phenomenological methodology to respond to the following research questions: What is the lifeworld of undergraduate nontraditional students with significantlife experience as they encounter college life? What resources sustain the college experience of undergraduate nontraditional students of and allow navigating the space of college life? What are the changes undergraduate nontraditional students live, the meaning they construct while encountering, and navigating college life?Themes that resulted from the analysis included the participants' experiences as essentially different from that of traditional students. These nontraditional college students bring skills and knowledge that they deploy on behalf of their specific academic goals. The pace of their lives is fundamentally different from the traditional universitystudent's sense of time; they are self-sufficient, making decisions and navigate obstacles.Their new identity as students is re-negotiated with the identities they live outside of campus and they establish ad hoc relationships with members of the universitycommunity.

Show moreFilm cooling is investigated on a flat plate both numerically and experimentally. Conical shaped film hole are investigated extensively and contribute to the current literature data, which is extremely rare in the open public domain. Both configuration of the cylindrical film holes, with and without a trench, are investigated in detail. Design of experiment technique was performed to find an optimum combination of both geometrical and fluid parameters to achieve the best film cooling performance. From this part of the study, it shows that film cooling performance can be enhanced up to 250% with the trenched film cooling versus non-trenched case provided the same amount of coolant. Since most of the relevant open literature is about film cooling on flat plate endwall cascade with linear extrusion airfoil, the purpose of the second part of this study is to examine the interaction of the secondary flow inside a 3D cascade and the injected film cooling jets. This is employed on the first stage of the aircraft gas turbine engine to protect the curvilinear (annular) endwall platform. The current study investigates the interaction between injected film jets and the secondary flow both experimentally and numerically at high Mach number (M=0.7). Validation shows good agreement between obtained data with the open literature. In general, it can be concluded that with an appropriate film coolant to mainstream blowing ratio, one can not only achieve the best film cooling effectiveness (FCE or η) on the downstream endwall but also maintain almost the same aerodynamic loss as in the un-cooled baseline case. Film performance acts nonlinearly with respect to blowing ratios as with film cooling on flat plate, in the other hand, with a right blowing ratio, film cooling performance is not affect much by secondary flow. In turn, film cooling jets do not increase pressure loss at the downstream wake area of the blades.

Show moreWith the increased prevalence of students qualifying for services within Autism Spectrum Disorder (ASD) programs (Odom, Cox and Brock, 2013), it is imperative that the field comes to better understand how successful programs can be replicated at scale. The implementation of effective instructional programs for students with ASD across school systems on a large scale is a difficult task. School systems have tried to replicate successful programs for diverse learners but have been largely unable to do so. For students with disabilities, who perform poorly compared to their peers without disabilities (Odom et al., 2013), the need to replicate successful programs is even more pressing. This need is most pressing for students in programs for ASD whose educational outcomes lag behind those of students in programs designed for all other exceptionality categories (Cook (&) Cook, 2013). The quality with which a program is designed matters little if the fidelity with which that program is implemented is lacking. For students with disabilities who perform poorly compared to their peers without disabilities (Odom et al., 2013), the need to replicate successful programs is even more pressing. The school leader plays an important role in the development, implementation, and maintenance of effective programs for students with ASD.The purpose of this study was to document the lived experiences of school leaders who have developed and/or managed successful programs for students with ASD within their school sites. It is clear that leadership matters in school and, therefore, influences program quality (Darling-Hammond, 2010; Reeves, 2006; Waters, Marzano, (&) McNulty, 2003). School and system change is difficult work, prone to being unsuccessful(-)but improvement is possible and sustainable (Fullan, 2007).The research questions for this study were:1.What are the characteristics of a school administrator who oversees effective self-contained classroom(s) for students with ASD?2.What are the lived experiences of principals who have led teachers to implement effective classrooms for students with ASD across their school setting?3.What rewards and challenges are associated with being a school administrator with an effective exceptional education program for students with ASD?In sum, these principal participants showed an intense interest in improving support services for students with ASD. They emphasized their vision that, if given the proper support and environment, all students can succeed. The principals were diligent in supporting that vision themselves and in making connections that could help reinforce that vision. A tremendous part of supporting that vision was ensuring that staff has the appropriate skills to work effectively with students with ASD. Once success was realized in these programs, it was reinforced by the success of the students and the emotional compensation received from parents. However, leading such programs is not without its challenges. Overall, though, all of these principals were clear about setting forth a path where the schools they were leading would do what is necessary to help their students with ASD be successful.

Show moreIn exploration of Millennial anxieties and the power of dreaming, The Gasoline Tree imagines a soundtrack for the revelations, defeats, and curiosities of leaving childhood behind. This is a collection of 40 poems that examines eating disorders, gender roles, physical abuse, sex, infidelity, loneliness, and the fear of losing one's parents. This collection also contemplates the brutalities and muted delights of what drives us all: love, in all of its forms. (")The Gasoline Tree,(") (")Wolf of Chocorua,(") and many other poems construct New England landscapes that pay homage to the pastoral uniqueness of Maxine Kumin and Galway Kinnell, while poems in the latter half of the collection, such as (")Home Alone(") and (")Little Big Econ,(") rouse depictions of southern environments and intensify the narrator's budding sense of displacement. There are many voices within, but there are three particular voices that can be heard above the rest: the child struggles with the complexities of divorce and identity; the young woman struggles with the complexities of remorse and relationships; the woman struggles with reminiscence and loss. Yet, each voice works toward expressions of awareness and acceptance of the enduring captivation with impermanence and consequence in a disposition influenced by W.S. Merwin, Anne Sexton, Kay Ryan, and Louise Gl(&)#252;ck. Whether driving by a homeless man, staring at the ceiling fan, or lying awake late into the night, this collection examines the transient nature of everyday occurrences and the buried meanings that might govern them all.

Research points to Latino/a parents as an important source of motivation and support for high achieving Latino/a students who are the first in their families to go to college (Arellano (&) Padilla, 2006; G(&)#225;ndara, 1982; 1994; Hurtado (&) Sinha, 2006; Zalaquett, 2005); however, very little is known about their experience as they parent children whose educational paths are so different from their own.

Show moreResearch points to Latino/a parents as an important source of motivation and support for high achieving Latino/a students who are the first in their families to go to college (Arellano (&) Padilla, 2006; G(&)#225;ndara, 1982; 1994; Hurtado (&) Sinha, 2006; Zalaquett, 2005); however, very little is known about their experience as they parent children whose educational paths are so different from their own. Cultural values such as collectivism and familism play a unique role in the level of connection between these parents and their children (Su(&)#225;rez-Orozco (&) Su(&)#225;rez-Orozco, 1995), creating dynamics that merit exploration. This dissertation qualitatively examines how seven Latino/a parents of first-generation college students pursuing a PhD expressed the parenting characteristics outlined in Parent Development Theory (Mowder, 2005). Furthermore, this study explores how these parents experienced their daughters' higher education journey. Moustakas' (1994) transcendental phenomenology was utilized in analyzing parents' voices. The textural and structural descriptions of major and minor themes provided the essence of the parents' experience. Example of themes are: (")Pero la Apoyo - Uncertainty and Support for the PhD("), (")Siempre Juntos - High Levels of Interaction("), and (")Amor Compasivo - Distance, Pain and Sacrifice("). Recommendations include support for pre-doctoral preparation initiatives, co-curricular innovations, and the exploration of the impact of modern technologies on the communication between parents and their children while in college.

Show more3D user interface technologies have the potential to make games more immersive (&) engaging and thus potentially provide a better user experience to gamers. Although 3D user interface technologies are available for games, it is still unclear how their usage affects game play and if there are any user performance benefits. A systematic study of these technologies in game environments is required to understand how game play is affected and how we can optimize the usage in order to achieve better game play experience.This dissertation seeks to improve the gaming experience by exploring several 3DUI technologies. In this work, we focused on stereoscopic 3D viewing (to improve viewing experience) coupled with motion based control, head tracking (to make games more engaging), and faster gesture based menu selection (to reduce cognitive burden associated with menu interaction while playing). We first studied each of these technologies in isolation to understand their benefits for games. We present the results of our experiments to evaluate benefits of stereoscopic 3D (when coupled with motion based control) and head tracking in games. We discuss the reasons behind these findings and provide recommendations for game designers who want to make use of these technologies to enhance gaming experiences. We also present the results of our experiments with finger-based menu selection techniques with an aim to find out the fastest technique. Based on these findings, we custom designed an air-combat game prototype which simultaneously uses stereoscopic 3D, head tracking, and finger-count shortcuts to prove that these technologies could be useful for games if the game is designed with these technologies in mind. Additionally, to enhance depth discrimination and minimize visual discomfort, the game dynamically optimizes stereoscopic 3D parameters (convergence and separation) based on the user's look direction. We conducted a within subjects experiment where we examined performance data and self-reported data on users perception of the game. Our results indicate that participants performed significantly better when all the 3DUI technologies (stereoscopic 3D, head-tracking and finger-count gestures) were available simultaneously with head tracking as a dominant factor. We explore the individual contribution of each of these technologies to the overall gaming experience and discuss the reasons behind our findings.Our experiments indicate that 3D user interface technologies could make gaming experience better if used effectively. The games must be designed to make use of the 3D user interface technologies available in order to provide a better gaming experience to the user. We explored a few technologies as part of this work and obtained some design guidelines for future game designers. We hope that our work will serve as the framework for the future explorations of making games better using 3D user interface technologies.

Show moreThe purpose of this research was to identify the extent to which a high school freshman transition program aligned with research based recommendations and to determine the extent to which the intervention impacted persistence to the tenth grade, on-track-to-graduation status, and academic success. Documents relevant to the program were collected and analyzed for research based themes. Students in the program at the target school were compared to students in a similar high school and a historical cohort of students who attended the target school. The impact of the course was statistically significant for persistence to the tenth grade, on-track to graduation status, and academic success; however ANOVA found statistical significance favored Algebra 1 EOC and not FCAT Reading. Effect size statistics revealed little to no effect among Freshman Experience and the dependent variables. These findings will help school-level and district administrators design research-based transition interventions which encourage academic success and graduation.

Show moreFactors affecting English learners' (ELs) motivation and identity have been explored in second language (L2) learning contexts; however, research examining L2 motivation and identity under the effect of bullying victimization is rare although ELs are one of the populations that are physically and psychologically affected from bullying. Using a unique perspective by merging L2 motivation, L2 identity, and bullying concepts under social ecological framework, this dissertation study is the first study investigating the relationship between bullying victimization, L2 Motivational Self System, and L2 identity.The data were derived from 1022 ELs through a self-report survey that was adapted and tested for measurement model validity and reliability. Partial least square structural equation modeling (PLS-SEM) results indicated that there was a strong relationship between bullying victimization, including traditional bullying and cyberbullying, L2 Motivational Self System, and L2 identity. Traditional bullying victimization and cyberbullying victimization affect ELs' feared L2 selves. This suggests that the feared L2 self may be added as a component to D(&)#246;rnyei's L2 Motivational Self System, especially when bullying victimization becomes a factor in language learning process. In addition, cyberbullying victimization positively correlated with ELs' oriented identity, which may indicate that ELs as agents were more motivated to learn English to overcome the negative effects of bullying victimization and to orient to the target culture. Based on the results, potential implications were provided for teachers and curriculum developers to help ELs cope with bullying in class and outside the classroom environment.
