Title: MODELING OF ATMOSPHERIC REFRACTION EFFECTS ON TRAFFIC NOISE PROPAGATION.
Creator: El-Aassar, Ahmed, Wayson, Roger, University of Central Florida
Abstract / Description: Traffic noise has been shown to have negative effects on exposed persons in the communities along highways. Noise from transportation systems is considered a nuisance in the U.S. and the government agencies require a determination of noise impacts for federally funded projects. There are several models available for assessing noise levels impacts. These models vary from simple charts to computer design models.

Show moreTraffic noise has been shown to have negative effects on exposed persons in the communities along highways. Noise from transportation systems is considered a nuisance in the U.S. and the government agencies require a determination of noise impacts for federally funded projects. There are several models available for assessing noise levels impacts. These models vary from simple charts to computer design models. Some computer models, i.e. Standard Method In Noise Analysis (STAMINA), the Traffic Noise Model (TNM) and the UCF Community Noise Model (CNM), have been used to predict geometric spreading, atmospheric absorption, diffraction, and ground impedance. However, they have largely neglected the atmospheric effects on noise propagation in their algorithms. The purpose of this research was to better understand and predict the meteorological effects on traffic noise propagation though measurements and comparison to acoustic theory. It should be noted that this represents an approach to incorporate refraction algorithms affecting outdoor noise propagation that must also work with algorithms for geometric spreading, ground effects, diffraction, and turbulence. The new empirical model for predicting atmospheric refraction shows that wind direction is a significant parameter and should be included in future modeling for atmospheric refraction. To accomplish this, the model includes a "wind shear" and "lapse rate" terms instead of wind speed and temperature as previously needed for input of the most used models. The model is an attempt to explain atmospheric refraction by including the parameters of wind direction, wind shear, and lapse rate that directly affect atmospheric refraction.

Show moreThis study examined the practices of Title I elementary school principals in the state of Florida for the school year 2009 - 2010. Elementary school principals in six Florida school districts responded to a survey to determine the extent of implementation of instructional and organizational practices identified by research to improve instruction and learning. The practices (sub-constructs) examined were identified as curriculum, instruction, assessment, educational agenda (vision, mission, beliefs, goals), leadership for school improvement, community building, and culture of continuous improvement. The results of this study indicated that participating Florida Title I principals believed that they were implementing effective instructional and organizational practices in their schools. Despite this belief, all but two of the schools represented in the results, failed to make adequate yearly progress (AYP) for school year 2009 - 2010. The analysis of the responses indicated a negative, but not statistically significant, correlation between self-reported scores and AYP percentage points earned. These results warrant further study to determine if the reported indicators can be verified by observation or other personnel. Within the limits of this study, the negative correlation suggested that school principals should examine their practices related to instructional and organizational effectiveness for fidelity and stakeholder buy-in. Principals must not only believe that these practices are evident, they must verify them through constant monitoring and quantitative measures.

Show morePrior research has established trickle-down effects (including trickle-out effects) in organizations, that is, perceptions, attitudes, and behavior may flow downward from an individual at a higher level of the organizational hierarchy (e.g., a supervisor) to another individual at a lower hierarchical level (e.g., a frontline employee), or from a frontline employee to an external member (e.g., a customer). Complementing the extant literature, this dissertation examines trickle-in effects, specifically, I examine whether customers' interpersonal and organizational deviance behavior will trickle-in through organizational boundary to influence a frontline employee's interpersonal and organizational deviance behavior.Specifically, I propose customers' interpersonal and organizational deviance behavior will trickle-in through organizational boundaries to affect employees' interpersonal and organizational deviance behavior. In addition, I develop a multiple-mediator model to test the different possible mechanisms underlying trickle-in effects: social exchange, social learning, displaced aggression, self-regulation, and social interactionist model. Two studies were conducted to test my propositions. In retail settings, Study 1 finds customers' interpersonal deviance behavior trickled-in through organizational walls to influence employees' interpersonal and organizational deviance behavior through displaced aggression mechanism. Study 2, collecting data from call centers, demonstrates customers' organizational deviance behavior trickled-in to influence employees' organizational deviance behavior through social learning processes.

Seventeen audio-taped in-depth interviews were conducted with college women who read beauty, fashion, and grooming magazines frequently. These interviews were transcribed, coded, and analyzed and the data developed into topics of importance. The findings indicated that informants perceived other women were influenced more by images of women in the media than they themselves were influenced. However, informants did not advocate behavior changes for others or hold pro-censorship attitudes. Other findings include favorable perceptions of magazines utilizing larger sized fashion models, negative attitudes towards advertising, and a reverse third-person effect when the 'other' is male. These findings are consistent with existing research on the third-person effect.

Effect, but very little pertains to the influence it has on individuals' perception of crime and their ability to get away with it. The study explores whether heavy viewers of crime show dramas such as Law & Order and C.S.I. display increased confidence in their ability to commit and get away with a crime. Essentially, this study explores whether these crime television shows are not only entertainment, but also may serve as guides on how to commit crimes. Participants in the study were University of Central Florida students. Participants read a description of a crime scene, and provided judgments from the criminal's point of view. They also completed the Crime Drama Viewing Questionnaire and the Levenson Psychopathy Scale in order to explore the possible correlation between reported confidence in "getting away" with criminal activity, type of television viewing, and psychopathy in participants. Using a correlational design, the relation between heavy and light crime drama viewing and criminal activity decision making was examined.The results of this study add to knowledge about how television crime drama potentially increases criminal confidence and competency in criminal behavior.

Show moreIt has been shown that popular crime television series can have an impact in the behavior and perception of viewers. Forensic evidence, or evidence that is gathered through scientific methods, is often central to the plot of these shows. Exposure to forensic evidence in these shows has impacted the legal system by changing perceptions and opinions towards evidence presented in courtrooms, a consequence termed the CSI effect. A subset of the CSI effect named the Police Chief's Effect refers to the ability of criminals to learn about forensic evidence from these shows. Although understudied, the Police Chief's effect has the potential to increase the difficulty of criminal investigations if criminals are better able to plan their actions and conceal evidence. The intent of this thesis is to explore a relationship between forensic techniques portrayed in television and the forensic knowledge an individual obtains from it. Previous studies have looked at the Police Chief's effect in the context of a non-violent crime, even though most of the television shows highlight crime of a violent nature. The present study evaluates the ability of participants to consider forensic evidence when planning a murder, taking into account their crime show viewing history. The results revealed that the overall number of crime shows, percentage of those episodes and involvement in the shows was not associated with forensic evidence. However, a moderate correlation was found between the number of crime shows watched and forensic evidence in female participants.

Show moreEndwall film cooling is a necessity in modern gas turbines for safe and reliable operation. Performance of endwall film cooling is strongly influenced by the hot gas flow field, among other factors. For example, aerodynamic design determines secondary flow vortices such as passage vortices and corner vortices in the endwall region. Moreover blockage presented by the leading edge of the airfoil subjects the incoming flow to a stagnating pressure gradient leading to roll-up of the approaching boundary layer and horseshoe vortices. In addition, for a number of heavy frame power generation gas turbines that use cannular combustors, the hot and turbulent gases exiting from the combustor are delivered to the first stage vane through transition ducts. Wakes induced by walls separating adjacent transition ducts located upstream of first row vanes also influence the entering main gas flow field. Furthermore, as hot gas enters vane passages, it accelerates around the vane airfoils. This flow acceleration causes significant streamline curvature and impacts lateral spreading endwall coolant films. Thus endwall flow field, especially those in utility gas turbines with cannular combustors, is quite complicated in the presence of vortices, wakes and strong favorable pressure gradient with resulting flow acceleration. These flow features can seriously impact film cooling performance and make difficult the prediction of film cooling in endwall. This study investigates endwall film cooling under the influence of pressure gradient effects due to stagnation region of an axisymmetric airfoil and in mainstream favorable pressure gradient. It also investigates the impact of wake on endwall film cooling near the stagnation region of an airfoil. The investigation consists of experimental testing and numerical simulation. Endwall film cooling effectiveness is investigated near the stagnation region on an airfoil by placing an axisymmetric airfoil downstream of a single row of inclined cylindrical holes. The holes are inclined at 35° with a length-to-diameter ratio of 7.5 and pitch-to-diameter ratio of 3. The ratio of leading edge radius to hole diameter and the ratio of maximum airfoil thickness to hole diameter are 6 and 20 respectively. The distance of the leading edge of the airfoil is varied along the streamwise direction to simulate the different film cooling rows preceding the leading edge of the airfoil. Wake effects are induced by placing a rectangular plate upstream of the injection point where the ratio of plate thickness to hole diameter is 6.4, and its distance is also varied to investigate the impact of strong and mild wake on endwall film cooling effectiveness. Blowing ratio ranged from 0.5 to 1.5. Film cooling effectiveness is also investigated under the presence of mainstream pressure gradient with converging main flow streamlines. The streamwise pressure distribution is attained by placing side inserts into the mainstream. The results are presented for five holes of staggered inclined cylindrical holes. The inclination angle is 30° and the tests were conducted at two Reynolds number, 5000 and 8000. Numerical analysis is employed to aid the understanding of the mainstream and coolant flow interaction. The solution of the computational domain is performed using FLUENT software package from Fluent, Inc. The use of second order schemes were used in this study to provide the highest accuracy available. This study employed the Realizable κ-ε model with enhance wall treatment for all its cases. Endwall temperature distribution is measured using Temperature Sensitive Paint (TSP) technique and film cooling effectiveness is calculated from the measurements and compared against numerical predictions. Results show that the characteristics of average film effectiveness near the stagnation region do not change drastically. However, as the blowing ratio is increased jet to jet interaction is enhanced due to higher jet spreading resulting in higher jet coverage. In the presence of wake, mixing of the jet with the mainstream is enhanced particularly for low M. The velocity deficit created by the wake forms a pair of vortices offset from the wake centerline. These vortices lift the jet off the wall promoting the interaction of the jet with the mainstream resulting in a lower effectiveness. The jet interaction with the mainstream causes the jet to lose its cooling capabilities more rapidly which leads to a more sudden decay in film effectiveness. When film is discharged into accelerating main flow with converging streamlines, row-to-row coolant flow rate is not uniform leading to varying blowing ratios and cooling performance. Jet to jet interaction is reduced and jet lift off is observed for rows with high blowing ratio resulting in lower effectiveness.

Show moreThe U.S. Army Training and Doctrine Command's Army Learning Concept 2015 and Army Training Concept 2025 are documents that discuss the need for an adaptive soldier learning model with a flexible training delivery methodology. The U.S. Army has been investing in serious gaming technology for the past two decades as a cost effective means to teach tactics and strategy. Today, the U.S. Army is seeking to expand its application of virtual environment training to areas such as cultural awareness and human network analysis for the infantry soldier. These new expanded applications will require a higher level of non-determinant behavior inside the virtual environment. To meet more of the training needs of the war fighter, the U.S. Army is looking beyond first person perspective games to the cooperative and social gaming experience offered by the MMOG (Massively Multiplayer Online Game) and the VWT (Virtual World Technology). Altogether, these classes of games have the potential to teach leadership skills, social acclimation skills, cultural awareness and practice skills, and critical thinking skills for problem solving in a cost effective manner. Unfortunately, even today there is a paucity of scientific research to support whether this potential may be realized or not. A literature review was performed which covers current concepts in the usage of virtual environments for military individual and team training in the U.S. Army infantry soldier domains. There are many variables involved with the lifecycle of the virtual training activity including the acquisition, information assurance and cyber security, deployment, proper employment, content development and maintenance, and retirement. This discussion goes beyond the traditional topics of graphics and game engine technology and delves deeper into concepts of the importance of proper usage of the environments by the trainees. This dissertation is composed of three studies with two subject pools: experienced soldiers and novice soldiers. The participants in the studies were randomly assigned to one of two training conditions. The training conditions were either a traditional slide-show in a classroom or a virtual environment based training system. The participants were then provided with training for a room clearing tasks in each of the conditions. The independent variables are training condition and soldier condition. The dependent variables are individual performance, team performance, stress questionnaire scores, and workload questionnaire scores. A number of relationships are explored in this dissertation. The first objective of these studies is to attempt to identify any effect the training conditions have on either individual performance or team performance. Lastly, these studies attempt to identify if there is any difference the training conditions have on novice versus experienced subjects' performance during a live assessment.

Show moreDiseases vectored by mosquitoes cause millions of deaths each year. In modern times Florida's disease risk has been reduced due to efforts to lessen the prevalence of mosquitoes through habitat modification of non-adults. With emerging diseases (i.e. Dengue and Chikunguya) encroaching into Florida from the Caribbean, this traditional approach may not be enough. Alternatively, we can better understand the ecology of how disease works in an ecosystem. One possible way is through the Dilution Effect, which states that the more species that are in a system the lower the chance for zoonosis. This project models mosquito diversity across regions, land use, and vegetation height in South-Central Florida, for the purpose of identifying predictors that indicate a higher disease risk using information theory (AICc). The plains and coastal regions as well as the developed areas have a relatively higher risk of disease. Florida is a fire maintained habitat, but has been fire suppressed for the last century. Archbold Biological Station (ABS) has used prescribed fires since the early 1980s to try and restore a more natural system. This has created a mosaic of different fire histories. Fire affects the structures that mosquitoes rest under during the day (they are vulnerable to desiccation during the day and hide in darker/shady places), therefore there is a high likelihood that fire will have some effect on mosquito assemblages. This project used model selection to determine the most plausible set of predictors that describe the effect of fire on mosquito assemblages at ABS, using information theory (AICc). In general, time of season accounted for the largest proportion of the variation in the data and TSF had negligible effect on adult mosquito assemblages measured as abundance, speices richness, and Jost D.

Records were selected so as to include an equal number of disease catagories dispersed equally over the two years. One hundred records were dated 1973 and 102 were dated 1976. Emphysema, chronic bronchitis, and asthma had been diagnosed in 67, 67, and 68 of the cases respectively. The age, sex, race, smoking habits, and occupations of the patients were recorded and crosstabulated with the diagnostic tests and subsequent treatment ordered by the various physicians. Most of the emphysematous patients were males over 50, the asthmatics were females under 30, and the bronchitics were older than 50 with an even sex distribution. Most of the emphysematous and bronchitic patients had smoked over 25 years, while only 13% of the asthmatics smoked. A majority of the chronic obstructive pulmonary disease patients complained of shortness of breath, were hospitalized ten days or less, treated four times a day with intermittent positive pressure breathing had little or no pulmonary rehabilitation, and survived. Respiratory care appeared to improve over the three-year period as judged by an increase in the frequency of blood gas monitoring and a reduction in the required ventilator times with improved techniques.

A great deal of research is going on for measuring the weight of moving vehicles. Weigh-in-motion of commercial vehicles is essential for management of freight traffic, highway infrastructure design and maintenance, and monitoring of heavy weight vehicles. The research work presents a methodology for correlating the weight of a moving vehicle with acoustic emission parameters (such as counts and energy). Furthermore, the correlation between the speed of vehicle with the acoustic emission parameters is developed. Preliminary analysis and experimentations were conducted for the study of propagation of acoustic signals in plate like structure and effect of dynamic loadings on Kaiser Effect. Initial testing revealed that there is a linear correlation between the impact force and the acoustic emission parameters. Also a polynomial regression of second order was found between the speed of vehicle and acoustic emission parameters. Road testing was conducted to investigate the correlation between weight of the vehicle and acoustic emission parameters. A linear relation was found between the weight of vehicle and acoustic emission parameters represented by counts, signal energy and absolute energy.

Show moreDavid Cash was a college student who found himself in the women's restroom of the Primadonna in Nevada. He witnessed his friend, Jeremy Strohmeyer raping and killing a 7-year-old girl. Cash did not take any action in trying to prevent this heinous crime. There are many elements to consider when bystanders neglect to take action. Research examining bystander apathy in critical situations is lacking, yet the number of violent crimes witnessed by others where intervention is not offered continues to escalate. Bullying often occurs in the presence of others. Bystander apathy is believed to play a passive role in most cases of bullying. This study investigated the psychological symptom patterns of intervening and non-intervening bystanders in bullying events. It was hypothesized that there would be a significant difference in the SLC-90-R profiles between intervening and non-intervening bystanders. It was further hypothesized that gender would significantly interact with the bystander response to witnessing bullying. Data were collected from undergraduate participants at the University of Central Florida through The Psychology Department's Psychological Research Participant System (aka, SONA). Psychological Symptoms were evaluated using the Symptom-Checklist-90-Revised (SCL-90-R). Data was obtained from 135 undergraduate participants. The sample consisted of 42 males and 93 females between 18 to 58 years of age. The participants were categorized by intervening and non-intervening bystanders. A two-way between subjects MANOVA was used to assess the influence of gender and intervening and non-intervening bystanders on the nine SLC-90-R symptom domains. No significant main effects or interaction was observed. However, a review of the univariate analyses revealed a significant gender x intervening interaction on the paranoid ideation subscale, F(1, 131) = 4.823, p = .03. Implications and directions for future research are discussed.

Show moreOver half (57%) of the women diagnosed with breast cancer are age 65 and older. Treatment for breast cancer may exacerbate current chronic illnesses and/or cause multiple treatment related side effects such as insomnia, fatigue, decreased physical functioning, alterations in body image, poorer quality of life, and changes in psychosocial health. While many women with breast cancer experience these changes, research suggests that older women have different needs than younger women and may not always benefit from interventions. The purpose of this integrative review of literature was to evaluate interventions designed to improve treatment related side effects in female breast cancer survivors age 65 years and older. This review of literature was conducted using CINAHL, PsycINFO, and MEDLINE databases using various key terms. Inclusion criteria consisted of peer reviewed research articles, women who have experience breast cancer, interventions directed at decreasing side effects, and research articles written in the English language.While using these search criteria, no interventions were found therefore, the age group was lowered to include women 50 and older. Eleven studies met the inclusion criteria. Interventions addressed a variety of treatment related side effects and were delivered in multiple formats. The findings indicate that interventions resulted in a significant improvement in sleep and fatigue, physical function, perception of body image, psychosocial health, and quality of life for older women with breast cancer. While these findings are positive, the literature did not break down results based on developmental stage or "older" age groups. Currently, there is limited literature that examines interventions in women age 65 and older, this may limit nurses' ability to suggest successful interventions to some of our oldest cancer survivors.

Show moreNonprofit capacity building programs and program activities positively influence perceived organizational effectiveness. Being able to link nonprofit capacity building to organizational effectiveness is a paramount concern for both nonprofits seeking capacity building programming and those entities, be it foundations or government that fund capacity building initiatives and programs. Therefore being able to link nonprofit capacity building to organizational effectiveness and higher performance is crucial to ensure that both nonprofit organizations and funders continue to pursue and support capacity building programming. Through an examination of the developing hollow state and the resulting nonprofit capacity disparity this study demonstrates the purposeful need for the continuation of nonprofit capacity building programming and the support of such programming through outside private foundation and government funding. Using a conceptual model developed from the literature on organizational learning and change this study examines the impact of capacity building programming, programming activities, organizational learning theory and perceived organizational effectiveness. The influence of the type of capacity building programming, i.e. traditional workshop and traditional workshop plus technical and financial assistance is investigated through the use of quantitative and qualitative methods. Specifically the quantitative methods utilized were descriptive including bi-variate correlation analysis, paired and independent T-tests, ANOVA and multiple regression. The qualitative analysis including examining open-ended survey question responses from two pre-post capacity building intervention surveys and one post program survey and the analysis of comments made in 10 focus groups. The influence of capacity building programming activities, i.e. organizational development, organizational program development, organizational collaboration and organizational leadership is investigated through the use of multiple regression and qualitative analysis. This study uses pre-, post-test survey data from a total of 43 nonprofit organizations that participated in the Strengthening Communities Fund in Central Florida Program, managed by the Center for Public and Nonprofit Management at the University of Central Florida. The two year program was offered in two identical 10 month cycles. Pre- and post-test data were collected from 23 participant organizations in Cycle 1 and 20 in Cycle 2. This study sought to identify the nonprofit capacity building programming modality and programming activities that contributed most to perceived organizational effectiveness. According to the findings, nonprofit organizations seeking capacity building and funders looking to support capacity building programs should look to programs that offer activities that increase organizational leadership capacity and organizational program development. Increasing organizational leadership capacity and organizational program development contributes most to perceived organizational effectiveness. This study did not find support to recommend one particular capacity building training modality over another. Regardless of the method of capacity building program delivery, i.e. workshop and/or technical and financial assistance, programs which build organizational leadership capacity and organizational program development will greatly influence the perceived organizational effectiveness of the capacity building participant organizations.

Title: THE EFFECTIVENESS OF STATE CERTIFIED, GRADUATE DEGREED, AND NATIONAL BOARD CERTIFIED TEACHERS AS DETERMINED BY STUDENT GROWTH IN READING.
Creator: Gardner, David, Murray, Kenneth, University of Central Florida
Abstract / Description: Federal, state, and local government agencies are promoting merit pay systems that are tied to student achievement. The main problem facing governments, school districts, and educators is that money is hard to come by in the current market and choosing where to spend merit pay monies to receive a maximum rate of return on the investment realized in increased student achievement is difficult to determine. This study did explore the student achievement results of third, fourth, and fifth grade...
Show moreFederal, state, and local government agencies are promoting merit pay systems that are tied to student achievement. The main problem facing governments, school districts, and educators is that money is hard to come by in the current market and choosing where to spend merit pay monies to receive a maximum rate of return on the investment realized in increased student achievement is difficult to determine. This study did explore the student achievement results of third, fourth, and fifth grade state certified, graduate degreed, and National Board Certified teachers in Brevard and Seminole County Public Schools as compared to those of other teachers within and across these schools. The goal of this study was to determine the effectiveness of state certified, graduate degreed, and National Board Certified teachers. For this study teacher effectiveness was defined by their studentsÃ‚Â' Lexile Framework for Reading scores from the 2008-2009 school year. The hypothesis is that the Lexile Framework for Reading data demonstrated that there was a statistically significant difference between the learning gains of the students between groups. Overall, the findings indicate that there was a statistically significant difference between the learning gains of the students between groups; however, that change could not be attributed to the factor of teacher category. Specific teacher education levels or certifications did not make any difference in the learning gains as measured by the Scholastic Reading Inventory (SRI), among 3rd, 4th, or 5th grade students in Brevard or Seminole County Public Schools.

Title: INFLUENCE OF THE CSI EFFECT ON EDUCATION AND MASS MEDIA.

Show moreForensic science television shows, especially CSI: Crime Scene Investigation, have been said to influence the public's perception of how forensic science is used and create interest in studying forensic science and pursuing jobs in the field. This study investigates this claim through a variety of methods. First, definitions of the CSI effect are discussed, including how it was first used and mentioned in the media. Second, survey data from students in a forensic anthropology course regarding interest in forensic science media and educational and career choices are analyzed. Third, the number and debut dates of forensic science non-fiction books, novels, non-fiction television shows, and television dramas are investigated. Finally, a content analysis of the television show Bones is undertaken in order to understand how the forensic anthropology presented in this show differs from the actual practice of forensic anthropology. Results of this study indicate that, overall, students who wanted to pursue forensic science careers and graduate study did not watch more forensic science television shows and read more forensic science novels than those who did not want to pursue forensic science careers and graduate study. Also, based on the decreased interest in a number of forensic careers, it appears that respondents may have started the course with false perceptions regarding the actual job descriptions of these careers. Regarding the number and debut dates of forensic science media, this study found that the majority of non-fiction forensic anthropology books, non-fiction television shows, television dramas debuted after CSI appeared, corroborating the claim that CSI led to an increase in interest in forensic anthropology. In addition, this study found that while much of Bones is fictionalized for entertainment purposes, many of the techniques and analyses presented on the show have a peripheral basis in scientific methods.
