Show moreWith advancement in technology, building structures are becoming bigger and more complex. Incidences of horrifying fires that occur in such complex structures resulting in loss of property as well as lives are recorded worldwide. Emergency evacuation training can play a crucial role in mitigating damage not only in cases of fire, explosion or chemical spill but also in cases of natural calamities like floods and hurricanes. Conventional safety training provided in industries mostly comprises of unidirectional flow of information. Due to this passive learning style, response of employees in real life emergency situations is known to be ineffective. The proposed research focuses on the development of virtual emergency evacuation safety training for residents, workers and employees. This research developed a 3 dimensional (3D) virtual fire safety and emergency evacuation training for building occupants. A 3D model of a real engineering college building in the University of Central Florida (UCF) was developed in a virtual world and participants could interact with various objects and scenarios in this virtual building on a standard desktop computer using keyboard and mouse. Expert interviews and literature review were utilized to develop contents of fire safety and emergency evacuation training. Also, a slide based fire safety and emergency evacuation training was developed based on same contents and made available through a website. An effort was made to develop both trainings- virtual and slide based to be comparable in terms of contents. A case study with two sets of experiments comprising of 143 participants from UCF community was conducted to understand factors such as fidelity, simulation sickness, engagement and effectiveness of 3D virtual and slide based fire safety and emergency evacuation training. Results of fidelity and simulation sickness validated use of 3D virtual training for training building residents on fire safety and emergency evacuation. Data analysis of knowledge tests allowed to compare short terms and long term effectiveness of 3D virtual training and slide based training. To further understand engagement, physiological measure- electroencephalograph (EEG) of 40 healthy participants was recorded in second set of experiments. Ratio of Beta and Alpha frequency bands was studied to understand attention paid by trainees in 3D virtual and slide based training.

Meta-analyses and systematic reviews of literature comparing the use of virtual patients (VPs) to traditional educational methods support the efficacy of VPs (Cook, Erwin, (&) Triola, 2010; Cook (&) Triola, 2009; McGaghie, Issenberg, Cohen, Barsuk, (&) Wayne, 2011). However, VP design research has produced a variety of design features (Bateman, Allen, Samani, Kidd, (&) Davies, 2013; Botezatu, Hult, (&) Fors, 2010a; Huwendiek (&) De Leng, 2010), frameworks (Huwendiek et al., 2009b) and...
Show moreMeta-analyses and systematic reviews of literature comparing the use of virtual patients (VPs) to traditional educational methods support the efficacy of VPs (Cook, Erwin, (&) Triola, 2010; Cook (&) Triola, 2009; McGaghie, Issenberg, Cohen, Barsuk, (&) Wayne, 2011). However, VP design research has produced a variety of design features (Bateman, Allen, Samani, Kidd, (&) Davies, 2013; Botezatu, Hult, (&) Fors, 2010a; Huwendiek (&) De Leng, 2010), frameworks (Huwendiek et al., 2009b) and principles (Huwendiek et al., 2009a) that are similar in nature, but appear to lack consensus. Consequently, researchers are not sure which VP design principles to apply and few validated guidelines are available. To address this situation, Huwendiek et al. (2014) validated an instrument to evaluate the design of VP simulations that focuses on fostering clinical reasoning. This dissertation examines the predictive validity of one instrument proposed by Huwendiek et al. (2014) that examines VP design features. Empirical research provides evidence for the reliability and validity of the VP design effectiveness measure. However, the relationship between the design features evaluated by the instrument to criterion-referenced measures of student learning and performance remains to be examined. This study examines the predictive validity of Huwendiek et al.'s (2014) VP design effectiveness measurement instrument by determining if the design factors evaluated by the instrument are correlated to medical students' performance in: (a) quizzes and VP cases embedded in Neurological Examination Rehearsal Virtual Environment (NERVE), and (b) NERVE-assisted virtual patient/standardized patient (VP/SP) differential diagnosis and SP checklists. It was hypothesized that students' perceptions of effectiveness of NERVE VP design are significantly correlated to the achievement of higher student learning and transfer outcomes in NERVE.The confirmatory factor analyses revealed the effectiveness of NERVE VP design was significantly correlated to student learning and transfer. Significant correlations were found between key design features evaluated by the instrument and students' performance on quizzes and VP cases embedded in NERVE. In addition, significant correlations were found between the NERVE VP design factors evaluated by Huwendiek et al.'s (2014) instrument and students' performance in SP checklists. Findings provided empirical evidence supporting the reliability and predictive validity of Huwendiek et al.'s (2014) instrument.Future research should examine additional sources of validity for Huwendiek et al.'s (2014) VP design effectiveness instrument using larger samples and from other socio-cultural backgrounds and continue to examine the predictive validity of Huwendiek et al.'s (2014) instrument at Level 2 (Learning) and Level 3 (Application) of Kirkpatrick's (1975) four-level model of training evaluation.

Show moreThis study examined the relationship between the professional practices components of the School Board of Brevard County Instructional Personnel Performance Appraisal System Instrument and student achievement as measured by a teacher's value-added measurement score. A Pearson Product-Moment Correlation was the statistical test used to analyze the data. The population included Brevard Public School instructional personnel assigned to Grades 4-10 who taught reading and/or mathematics measured by the Florida Comprehensive Assessment Test during the 2011-2012 school year and who received teacher aggregated value-added measurement scores.Findings indicated that there was a small to moderate statistically significant, positive relationship between all eight professional practices component variables and value-added measurement scores. Correlation coefficients ranged from .089 for collaborative inquiry to .218 for quality of instruction. All of the components combined had a correlation of .231, confirming the strength of multiple evaluation measures.Recommendations were provided for future research aimed at further data analysis in Brevard Public Schools as well as other school districts in order to identify the combination of evaluation components that most accurately reflect teaching effectiveness resulting in student learning as well as to pinpoint weaknesses upon which additional training could be based and the fidelity of implementation improved.

Show moreMolecular magnets with different dimensionality, whether they are zero-dimensional single-molecule magnets (SMM) or one-dimensional single-chain magnets (SCM) are very interesting, since they allow probing the fundamental aspects bordering quantum and classical physics at the nanoscale level. This dissertation covers experimental studies of two Mn-based exchange-coupled molecule-based magnets and two Co-based single-chain magnets, using both dc Hall-effect magnetometry and electron paramagnet resonance (EPR) techniques. In these multi-dimensional systems, the spin of the molecule exhibits quantum mechanical behavior at low temperature. It is quite interesting to observe the effect of magnetic exchange interactions on the magnetic properties of various complexes; hence they strongly affect the magnetic behavior.In this dissertation, the research is initiated with the study of low-magnetic-nuclearity molecules, starting with a spectroscopic study of a significantly anisotropic Mn(IV) monomer. At low temperature the molecule possesses easy-plane type anisotropy of a remarkable magnitude. Although the molecule is not a single-molecule magnet, the remarkable anisotropy can initiate synthesis of newer and better molecular magnets with Mn(IV) as the main building block. Furthermore, the interplay between the magnetic anisotropy and the inter-ion exchange interactions (J) within the molecule are probed for a dimer and a trimer where the magnetic core is comprised of two and three ions respectively. In the Mn-based case of the dimer, the low coupling between the atoms leads to significant state mixing, thus making it impossible to assign the individual spin states to the dimer or to the respective individual Mn(II) ions. In the case of the trimer, lowering of the symmetry achieved by fine tuning of the inter-ion exchange interactions leads to relieving of frustration in the antiferromagnetic (AF) triangular Mn(III) system, resulting in a well defined ground state and significant zero field splitting. Also a clear hysteretic behavior observed in this system demonstrates its SMM nature at low temperature. Finally, high-field high-frequency magnetic and spectroscopic studies performed on two cobalt-based SCMs reveal that formation of magnetic domains by exchange interactions within the chain are strongly influenced by thermal fluctuations. The chain possesses a uniaxial anisotropy with the quantization axis lying along the length of the chain. Moreover it is shown that modulation of the magnitude of inter- and intra-chain interactions results in a three-dimensional dynamics in one of the samples. Interestingly, detailed dc magnetic studies show a tunable crossover between one- and three-dimensional magnetic dynamics as a function of temperature and/or magnetic field sweep rate. Our voyage through several molecular systems of different dimensionality have allowed us to expand our understanding of the role of exchange interactions on the magnetic behavior in molecular magnetism.

Show moreThe purpose of this study was to determine the immediate and long term impact of participation in the 2009 Third Grade Summer Reading Camp, as well as determine the cost-effectiveness of providing this program in comparison to the cost-effectiveness of other reading interventions as identified by Yeh (2010). All students in this study scored an achievement level one on the 2009 FCAT Reading assessment and either attended the summer reading camp or received a good cause exemption for promotion to the next grade level. Data was not available to determine immediate impact of summer school. To determine long term impact of summer school participation, 130 students who attended the program and passed were compared to a random sample of 130 students who received another good cause exemption. Results of an independent t-test indicated students who passed summer school by performing at or above the 50th percentile on the alternative assessment outperformed students who received another good cause exemption on the 2010 FCAT Reading assessment, t(258) = -9.50, p = .000, effect size r = 0.51,and 2011 FCAT Reading assessment, t(258) = -7.43, p = .000, effect size r = 0.42. Ninety percent of students who attended summer school and passed the alternative assessment for promotion made learning gains on the following year's FCAT Reading assessment; however, the majority of students performed below grade level on the 2010 and 2011 FCAT Reading assessment. Based on school district records for the cost of salaries, benefits, transportation, materials, and supplies, the total cost of summer school was calculated and adjusted for inflation to 2006 dollars so a comparison could be made to Yeh's (2010) cost-effectiveness analysis of summer school and other reading interventions that annualized the cost to 2006 dollars. The adjusted cost for the 2009 summer reading program was calculated at $872,681.23. Using this number and dividing by the total number of summer school student, which were 3,012 students, the cost per student annualized to 2006 was $289.74. Data to determine the immediate impact of summer school were not available, therefore, student performance on the 2009 FCAT Reading assessment was compared to their performance on the 2010 FCAT Reading assessment by calculating a paired samples t-test, t(1225) = 40.82, p = .000, d = 1.23, effect size r = 0.52. The effect size d was divided by the cost per student which calculated an effectiveness-cost ratio of 0.004245 compared to that derived by Yeh (2010) of 0.000125. Caution should be taken when interpreting these results as methodology was not in alignment to Yeh (2010) due to the lack of an immediate post-test measure after participation in summer school and an additional year of interventions and education is reflected in the test scores. The cost per student was calculated to be $1,225.26 less than the amount of money reported in Yeh's (2010) calculations. Based on this information, the diminishing effect of the summer school program on student reading performance in subsequent years, and the majority of students performing below grade level one and two years after summer school participation, it cannot be determined that this program is cost-effective in raising student reading achievement.It is recommended that this study be replicated with adjustments made to address the limitations identified. Further investigation should be made at the state level to determine if the current practice of good cause exemptions and summer school offerings perpetuates the achievement gap in reading.?

Show moreThis thesis examines the effects of war on a state's economy. The Liberal Theory of international relations maintains that there are costs to war in terms of trade; in line with this argument, many researchers have suggested that trading partners are less likely to war with each other out of a fear of disrupting their trade, which would in turn disrupt their economies. Due to issues of elasticity and substitution, however, overall trade may not significantly decline during war. Additionally, there are known economic costs of war, such as debt. If war truly does have costs, then, it must be more in terms of costs to the national economy, rather than trade. This work examines the theory that war has costs to the economies of war initiators, and samples the economies of war initiators from the mid-nineteenth century to the late twentieth century. This paper uses a time series analysis and tests for anterior, concurrent, and posterior effects of war initiation on national economies, and uses a time period of up to twenty years before and after each war event. The results indicate that there are, in general, no negative effects of war on a state's economy: only one case had a significant negative result, while two had significant positive results; these two positive cases, however, also had strong evidence of autocorrelation. These results pose a challenge to the Liberal Theories of International Relations.

Show moreThe primary aim of this study is to discover how leadership competencies affect the perceived effectiveness of crisis management. Leadership skills exhibited by public managers in crisis times may help eliminate panic and help victims recover from the difficult situation as soon as possible. The existence of effective leadership in a crisis is one of the most important inputs in order to diminish the harmful effects of crises and disasters. The absence of effective leadership in times of crisis may be one of the most significant problems in the public administration because it may result in loss of human life and property. By answering the following research questions this study provides useable knowledge for public managers and leaders during crises: Are there any different leadership features or characteristics for effective leadership at time of crises than the leadership in normal time? What is the role of effective leadership in managing crises and disasters (natural or man-made)? How do a public administrator's leadership traits and skills impact the effectiveness of crisis leadership? How do a public administrator's leadership behaviors (task-, people-, and organization-oriented behaviors) influence the effectiveness of a crisis leadership? With the aim of revealing these relations, a self-reported survey was sent to 2,095 current and former Turkish public security network managers. The study found that the core leadership competencies (decisiveness, flexibility, communication, problem solving, managing innovation and creativity, team building, managing and organizing personnel, motivating, networking and partnering, decision making, scanning the environment, and strategic planning) have a positive relationship with the effectiveness of crisis leadership. Among three categories of leadership behaviors, task-oriented leadership behaviors were found with the highest level of impact on the effectiveness of crisis leadership. The study indicated the importance of the core leadership competencies in the effectiveness of crisis leadership. According to the results, the hypothesis testing with the covariance structure model supported the positive impact of the core leadership competencies on the effectiveness of crisis leadership. This study contributes to the literature on leadership during crisis situations, and also provides proposals for public managers and practitioners in order to increase their effectiveness in leading their organizations during a crisis situation.

Show moreThere is an increasing interest in using video games as a means to deliver training to individuals learning new skills or tasks. However, current research lacks a clear method of developing effective instructional material when these games are used as training tools and explaining how gameplay may affect learning. The literature contains multiple approaches to training and GBT but generally lacks a foundational-level and theoretically relevant approach to how people learn specifically from video games and how to design instructional guidance within these gaming environments. This study investigated instructional delivery within GBT. Video games are a form of multimedia, consisting of both imagery and sounds. The Cognitive Theory of Multimedia Learning (CTML; Mayer 2005) explicitly describes how people learn from multimedia information, consisting of a combination of narration (words) and animation (pictures). This study empirically examined the effects of the modality and temporal contiguity principles on learning in a game-based virtual environment. Based on these principles, it was hypothesized that receiving either voice or embedded training would result in better performance on learning measures. Additionally, receiving a combination of voice and embedded training would lead to better performance on learning measures than all other instructional conditions.A total of 128 participants received training on the role and procedures related to the combat lifesaver (-) a non-medical soldier who receives additional training on combat-relevant lifesaving medical procedures. Training sessions involved an instructional presentation manipulated along the modality (voice or text) and temporal contiguity (embedded in the game or presented before gameplay) principles. Instructional delivery was manipulated in a 2x2 between-subjects design with four instructional conditions: Upfront-Voice, Upfront-Text, Embedded-Voice, and Embedded-Text. Results indicated that: (1) upfront instruction led to significantly better retention performance than embedded instructional regardless of delivery modality; (2) receiving voice-based instruction led to better transfer performance than text-based instruction regardless of presentation timing; (3) no differences in performance were observed on the simple application test between any instructional conditions; and (4) a significant interaction of modality-by-temporal contiguity was obtained. Simple effects analysis indicated differing effects along modality within the embedded instruction group, with voice recipients performing better than text (p = .012). Individual group comparisons revealed that the upfront-voice group performed better on retention than both embedded groups (p = .006), the embedded-voice group performed better on transfer than the upfront text group (p = .002), and the embedded-voice group performed better on the complex application test than the embedded-text group (p =.012). Findings indicated partial support for the application of the modality and temporal contiguity principles of CTML in interactive GBT. Combining gameplay (i.e., practice) with instructional presentation both helps and hinders working memory's ability to process information. Findings also explain how expanding CTML into game-based training may fundamentally change how a person processes information as a function of the specific type of knowledge being taught. Results will drive future systematic research to test and determine the most effective means of designing instruction for interactive GBT. Further theoretical and practical implications will be discussed.

The differences between instrumental music participation groups were not found to be statistically significant for both the reading and mathematics FCAT 2.0 growth by high-SES status students, and for reading FCAT 2.0 growth by low-SES status students. The differences between groups were found to be significant for mathematics FCAT 2.0 growth by low-SES students, but a Tukey HSD post-hoc test found no significant differences between the individual groups. The study also found that high-SES students had a higher rate of instrumental music participation in sixth grade, and a lower attrition rate between sixth and seventh grade than the low-SES students.

Show moreCMOS RF circuit design has been an ever-lasting research field. It gained so much attention since RF circuits have high mobility and wide band efficiency, while CMOS technology has the advantage of low cost and better capability of integration. At the same time, IC circuits never stopped scaling down for the recent many decades. Reliability issues with RF circuits have become more and more severe with device scaling down: reliability effects such as gate oxide break down, hot carrier injection, negative bias temperature instability, have been amplified as the device size shrinks. Process variability issues also become more predominant as the feature size decreases. With these insights provided, reliability and variability evaluations on typical RF circuits and possible compensation techniques are highly desirable.In this work, a class E power amplifier is designed and laid out using TSMC 0.18 (&)#181;m RF technology and the chip was fabricated. Oxide stress and hot electron tests were carried out at elevated supply voltage, fresh measurement results were compared with different stress conditions after 10 hours. Test results matched very well with mixed mode circuit simulations, proved that hot carrier effects degrades PA performances like output power, power efficiency, etc. Self- heating effects were examined on a class AB power amplifier since PA has high power operations. Device temperature simulation was done both in DC and mixed mode level. Different gate biasing techniques were analyzed and their abilities to compensate output power were compared. A simple gate biasing circuit turned out to be efficient to compensate self-heating effects under different localized heating situations. Process variation was studied on a classic Colpitts oscillator using Monte-Carlo simulation. Phase noise was examined since it is a key parameter in oscillator. Phase noise was modeled using analytical equations and supported by good match between MATLAB results and ADS simulation. An adaptive body biasing circuit was proposed to eliminate process variation. Results from probability density function simulation demonstrated its capability to relieve process variation on phase noise. Standard deviation of phase noise with adaptive body bias is much less than the one without compensation. Finally, a robust, adaptive design technique using PLL as on-chip sensor to reduce Process, Voltage, Temperature (P.V.T.) variations and other aging effects on RF PA was evaluated. The frequency and phase of ring oscillator need to be adjusted to follow the frequency and phase of input in PLL no matter how the working condition varies. As a result, the control signal of ring oscillator has to fluctuate according to the working condition, reflecting the P.V.T changes. RF circuits suffer from similar P.V.T. variations. The control signal of PLL is introduced to RF circuits and converted to the adaptive tuning voltage for substrate bias. Simulation results illustrate that the PA output power under different variations is more flat than the one with no compensation. Analytical equations show good support to what has been observed.

Show moreWithin the exciting current trend to explore novel low-dimensional systems, the possibility to injectpure spin currents in graphene and other two-dimensional crystals has attracted considerableattention in the past few years. The theoretical prediction of large spin relaxation times and experimentally observed mesoscopic-scale spin diffusion lengths places graphene as a promising base system for future spintronics devices. This is due to the unique characteristics intrinsic to the two-dimensional lattice of carbon atoms forming graphene, such as the lack of nuclear spins and weak spin-orbit coupling of the charge carriers. Interestingly for some spintronic applications, the latter can be chemically and physically engineered, with large induced spin-orbit couplings found in functionalized graphene sheets. Understanding spin injection, spin current and spin dynamics in graphene is of a great interest, both from the fundamental and applied points of view.This thesis presents an experimental study of dynamical generation of spin currents in macroscopic graphene sheets by means of spin pumping from the precessing magnetization of an adjacent ferromagnet. The spin pumping characteristics are studied by means of ferromagnetic resonance (FMR) measurements in Permalloy/graphene (Py/Gr) bilayers. Changes in the FMR linewidth induced by the presence of graphene (when compared to studies with only Py films) correspond to an increase in the Gilbert damping in the ferromagnetic layer (proportional to the FMR linewidth) and interpreted as a consequence of spin pumping at the Py/Gr interface driven by the Py magnetization dynamics (i.e., magnetic induced by the microwave stimulus). FMR experiments are performed on different FM/Gr interfaces, completing a set of studies designed to systematically identify and eliminate damping enhancement arising from processes other than spin pumping. Remarkably, a substantial enhancement of the Gilbert damping observed in Py/Gr strips with graphene protruding a few micrometers from the strip sides is univocally associated to spin pumping at the quasi-onedimensional interface between the Py strip edges and graphene. This increase in the FMR linewidth compares with observations in other bilayer systems, in where thick (thicker than the spin diffusionlength) layers of heavy metals with strong spin-orbit coupling are employed as the non-magneticlayer, indicating that spin relaxation in chemically grown graphene must be greatly enhanced in order to account for the losses of angular momentum lost by the ferromagnet. The fundamentalimplications of the results presented in this thesis point to a non-trivial nature of the spin pumping mechanism owing to the two-dimensionality of the non-magnetic layer (i.e., graphene).In addition, a spintronics device designed to interconvert charge and spin currents has been designed. A high-frequency microwave irradiation lock-in modulation technique is employed todetect the small electrical voltages generated by the inverse spin Hall effect (ISHE). As a proofof principle, a successful spin-charge interconversion in Py/Pt-based devices is experimentally demonstrated in this thesis. The challenges associated with the spin-charge interconversion in twodimensional devices are discussed and systematically addressed, and a potential device geometry for measuring the ISHE in Py/Gr-based systems is provided.

Show moreMigration is a widespread and complex phenomenon in nature that has fascinated humans for centuries. Connectivity among populations influences their demographics, genetic structure and response to environmental change. Here, I used the loggerhead turtle (Caretta caretta, L.) as a study organism to address questions related to migratory connectivity and carry-over effects using satellite telemetry, stable isotope analysis and GIS interpolation methods. Telemetry identified foraging areas previously overlooked for loggerheads nesting in Florida. Next, I validated and evaluated the efficacy of intrinsic markers as a complementary and low cost tool to assign loggerhead foraging regions in the Northwest Atlantic Ocean (NWA), using both a spatially implicit and spatially explicit (isoscapes) approach. I then focused on the nesting beaches and developed a common currency for isotopic studies based on unhatched eggs, which provide a non-invasive and non-destructive method for more extensive sampling to elucidate isotopic patterns across broader spatiotemporal scales. Lastly, I found that intra-population variations in foraging strategies affect annual and long-term reproductive output of loggerheads nesting in Florida. Understanding geospatial linkages is critical to the fostering of appropriate management and conservation strategies for migratory species. My multi-faceted approach contributes to the growing body of literature exploring migratory connectivity and carry-over effects.

Show moreThe aim of this study is to examine the predictors of effective performance measurement in the context of Turkish municipalities. In the study, mainly the theoretical guidance of context-design-performance model has been utilized to examine the contextual and design factors which have influenced the effective use of performance measurement systems in Turkish municipalities. The following research questions were examined in this study: To what extent do Turkish municipalities implement performance measurement systems effectively?, What are the predictors of effective performance measurement in Turkish municipalities?, and whether or to what extent do quality of performance measures, technical capacity of the municipality for performance measurement, organizational support, and external support for the use of performance measurement have influence on the effectiveness level of performance measurement systems in Turkish municipalities? In the study, the data were collected from Turkish municipalities by a self-administered online survey and were analyzed by using the structural equation modeling (SEM). It is hypothesized in the study that external support and organizational support for the use performance measurement, and technical capacity for the performance measurement are associated with quality of performance measures and effectiveness of performance measurement systems in general. The results of the study supported the hypotheses of the study regarding the relationships among organizational support, technical capacity, quality of performance measures, and effectiveness of performance measurement. Although the results confirmed that external support has an indirect effect on effectiveness of performance measurement via technical capacity and quality of performance measures, the hypothesis regarding the direct effect of it on effectiveness of performance measurement was not supported. Moreover, the study found that support of employees and citizens for the use of performance measurement in Turkish municipalities are relatively low, the municipalities have deficiencies both in the quantity and the quality of staff that are responsible for performance measurement activities, and the level of employee involvement in the development of performance measures is low.

Show moreOrthodox optical devices, such as lenses, mirrors, and prisms, are composed of solid-state materials, which although well studied and implemented ubiquitously are severely limited in their adaptable properties. An arguably new field of adaptive optics has emerged to further expand photonic manipulation competences of optical components. Fluid-based adaptive optical components were introduced as early as 1968; such components have the ability to change the shape of their interface surface, thus allowing for a variable curvature profile. The method of manipulation varies greatly, as does the range of surface deformations. A solid-state optical component is affected by system vibration variation only (difference in vibration from one component to the other due to damping effect). By comparison, two large limiting factors of a fluid-based adaptive optical component are the effect of local vibrations on the surface of the device and gravitational effect (when the optical axis of a lens is positioned parallel to gravitational pull). Such a gravitational effect has been mitigated by the invention of the mechanical electrowetting lens, which uses density matching of two liquids that make up an adaptive lens. However, this configuration creates an extra limiting factor of density matching two optically clear fluids with a desirable transmission spectrum. This method can also become bulky when a large aperture is needed. In this thesis, two adaptive lens systems are explored. Principles of operation, performance, limitations, as well as future improvements are studied and theorized. The first lens uses an optically clear elastomer as the substrate of an adaptive lens and a primitive mechanical manipulation to turn a plano(-)plano lens into a plano(-)convex lens. The second lens is composed of an optically clear gel rather than a fluid. Both methods exhibit excellent optical properties regardless of the orientation about the gravitational pull and significantly limit local vibration affects simply by the physical nature of the chosen materials.

Show moreThe purpose of this study was two-fold: (a) to determine the relationship between the number of classroom observations and teacher VAM scores and (b) to identify the relationship between the types of feedback provided to teachers and student achievement outcomes as measured by VAM scores. De-identified data for the sample set of teachers in a large urban school district was gathered for the 2013-2014 year from iObservation by administrators observing teachers using the domains of the Marzano instructional model. The number of observations were compared to VAM scores to determine if teachers with a greater number of observations received higher VAM ratings. The comments recorded and submitted as feedback were also reviewed. Data were analyzed to identify relationships between the types of feedback provided to teachers and student achievement outcomes as measured by VAM scores. No significant relationship existed between VAM scores and number of observations or percentage of comments for teachers at any grade level. In addition, no significant relationship existed between predominant feedback for teachers and VAM scores.The information in this study was valuable for understanding the relationships that exist among instructional practice scores, value-added measures, and learning gains to drive conversations with teachers regarding rigorous instruction. Observations and feedback should be a tool for improvement of instruction, but the data confirmed this process continues to be compliance based with inflated scores that do not match the level of performance of students. Changing this is strongly linked to the provision of feedback associated with improving instruction and holding teachers accountable in meeting the standards outlined in the feedback. Observers are in need of professional development on how to provide effective feedback in the areas of instruction that will make the biggest impact on student achievement. Continuing to put time and effort into implementing and monitoring evaluation systems without further training and emphasis on feedback will result in the same lack of impact on student achievement outcomes and may even undermine the role of observers in providing support to teachers.

Show moreThe Weapon Combat Effectiveness (WCE) analytics is very expensive, time-consuming, and dangerous in the real world because we have to create data from the real operations with a lot of people and weapons in the actual environment. The Modeling and Simulation (M(&)S) of many techniques is used for overcoming these limitations. Although the era of big data has emerged and achieved a great deal of success in a variety of fields, most WCE research using the Defense Modeling and Simulation (DM(&)S) techniques were studied without the help of big data technologies and techniques. The existing research has not considered various factors affecting WCE. This is because current research has been restricted by only using constructive simulation, a single weapon system, and limited scenarios. Therefore, the WCE analytics using existing methodologies have also incorporated the same limitations, and therefore, cannot help but get biased results.To solve the above problem, this dissertation is to initially review and compose the basic knowledge for the new WCE analytics methodology using big data and DM(&)S to further serve as the stepping-stone of the future research for the interested researchers. Also, this dissertation presents the new methodology on WCE analytics using big data generated by Live, Virtual, or/and Constructive (LVC) simulations. This methodology can increase the fidelity of WCE analytics results by considering various factors. It can give opportunities for application of weapon acquisition, operations analytics and plan, and objective level development on each training factor for the weapon operators according to the selection of Measures of Effectiveness (MOEs) and Measures of Performance (MOPs), or impact factors, based on the analytics goal.

Show moreThis phenomenological study examined the lived experiences of special education teachers who worked with students with emotional behavioral disabilities (EBD) across various urban settings and educative environments. Given that the overall percentage of students receiving special education services has increased, the overall percentage of students with EBD served among all school-aged children and youth has remained below 1% (U.S. Department of Education, National Center for Education Statistics, 2018). The current failings of reform efforts to improve the academic achievement of students with EBD brings the roles, responsibilities and practices of teachers and their preparation into view. This study examined the impact of culture on the attitudes, beliefs, and practices of special education teachers. Semi-structured interviews were conducted with eight participants (N = 8). A thematic analysis resulted in three overarching themes. The three themes included: (a) the essentials: keys to student engagement, (b) the frustrations regarding effective program implementation, and (c) elements of an effective program. This study exposed multiple factors affecting the effectiveness of special educators' practices as well as offered recommendations for teachers, schools, districts, policies, and future research.

Show morePlacement into educable mentally handicapped (EMH) programs is necessary for some students in order to allow them the opportunity to receive an education appropriate for their special needs. Nonetheless, identification as EMH is often perceived as negative and demeaning. Decades of research have substantiated the over-representation of black students into certain categories of special education, including EMH, in comparison to white and Hispanic students. This disparity has raised questions within schools, academe and research communities, and legislative and governing bodies as to the causes, compelling factors, and related variables impacting the phenomenon. This study investigated the apparent over-representation of blacks identified as EMH in the 67 public school districts in Florida in 2001-2002. It also analyzed the effects certain school district characteristics had on the identification of white, black, and Hispanic students as EMH. Analysis of data derived from the Florida Department of Education database for school year 2001-2002 led to the following findings: (1) there was over-representation of blacks in EMH within the 67 public school districts in Florida, since results showed that blacks were identified as EMH 2.5 times more often than whites and Hispanics; (2) socioeconomic status of school districts had a significant effect on the identification of black students as EMH,for example, when the school district was identified as a high socioeconomic status district, there was a greater likelihood that a larger proportion of black students would be identified as EMH; (3) as the wealth of school districts rose, there was a significant likelihood that the proportion of black students identified as EMH would also rise; (4) black students had a greater likelihood of being identified as EMH in suburban school districts; (5) blacks were over-identified in school districts that had 60,000 to 89,000 students; (6) when there was a high percentage of white, full-time, non-instructional staff (80% or more) in school districts, blacks had a greater likelihood of being over-identified as EMH; (7) blacks were three times more likely to be identified as EMH regardless of the type of degrees teachers had; and, (8) as district expenditure per student (FTE) increased, the tendency for over-identification of blacks as EMH decreased. For every variable analyzed, the proportion of black students identified as EMH was significant when compared to the proportions of white and Hispanic students also identified as EMH.

Show moreThe present study identifies the dimensions and variables using prior research within each of the constructs under the management systems, fit and, organizational strategy, structure, lifecycle and performance. The constructs from the research model were defined with a combination of direct, calculated and coded measures. Context analysis for each case categorized management systems design into either prescriptive or descriptive. The selected performance measures have been extensively investigated in the research fields associated with organizational management. The study uses the multiple case study design with cross-sectional data spanning from 1991 to 2005 and involving 19 aerospace companies in the United States. A priori hypothesized relationships between the constructs were tested with Mann-Whitney procedures for differences between mean ranks associated with organizational performance measures. The results from Mann-Whitney tests suggest that there exist significant differences in organizational performance from fit factors between a management system design and the organization. Present study defined organizational performance measures for analysis in terms of Return on Assets, Return on Equity and Return on Investment. When compared to a prescriptive management system design, a descriptive management system design was associated with higher levels of organizational performance. Cases with a fit state were found to score significantly higher than cases with unfit state suggesting that a correct fit state is associated with higher levels of organizational performance. A fit state was associated with higher levels of performance when each of the organizational factors for strategy, structure and lifecycle were aligned to management system design. Study results suggest equifinality as cases reached a particular fit state with differing combinations of fit factors. The study contributes to the field with interpretation of a fit model and key relationship between management systems and performance providing the base for future research efforts associated with management systems, organizational factors and the fit between them.

Show moreA framework was developed called the Extended Hedonomic Hierarchy (EHH) that provides a basis for evaluating pleasurable human-system experience. Results from a number of experiments within this framework that evaluated specific dimensions of the framework are reported. The 'Exposure' component of the EHH framework and hedonics of the system were investigated to see how changes would affect other dimensions, such as the occurrence of flow, the mode of interaction, and the needs of the user. Simulations and video games were used to investigate how repeated exposure affects flow, interaction mode, and the user needs. The Kansei Engineering method was used to measure user needs and investigate the effect of different hedonic properties of the system on user needs and flow. Findings reveal that: (a) pleasurable human-system experience increases linearly with repeated exposure to the technology of interest; (b) an habituation effect of flow mediated by day; (c) motivation to satisfy human need for technology is hierarchically structured and contributes to pleasurable human-system experience; (d) interactivity is hierarchically structured and seamless mode of interaction is a behavioral outcome of pleasurable human-system experience; (e) there are individual differences among users that affect the likelihood of experiencing pleasurable human-system interaction; (f) performance is positively correlated to flow and (g) the method of kansei engineering provides data from which informed decisions about design can be made and empirical research can be conducted. Suggestions for (a) making Hedonomics a reality in industry, the workplace, and in the field of Human Factors, (b) future research directions for Hedonomics, and (c) principles and guidelines for the practice of Hedonomics are discussed.
