Show moreThis dissertation investigates two stellar systems known to contain extrasolar planets. It is comprised of five chapters that are readily divided into three independent but related analyses. Chapter 1 reports on the analysis of low signal-to-noise secondary-eclipse observations of the Neptune-sized exoplanet GJ 436b using the Spitzer Space Telescope in multiple infrared channels. The measured wavelength-dependent eclipse depths provide constraints on the planet's dayside atmospheric composition and thermal profile. The analysis indicates that GJ 436b's atmosphere is abundant in carbon monoxide and deficient in methane relative to thermochemical equilibrium models for the predicted hydrogen-dominated atmosphere.Chapter 2 discusses the techniques used to analyze GJ 436b, introduces the Least Asymmetry centering method and compares its effectiveness to two existing techniques, and describes the functions used to model Spitzer's position- and time-dependent systematics. Additionally, it includes best-fit parameters with uncertainties, histograms of the free parameters, and correlation plots between free parameters.Chapter 3 reports on the analysis of eleven HD 149026b secondary-eclipse observations at five Spitzer wavelengths plus three primary-transit observations at 8.0 microns. Chemical-equilibrium models find no indication of a temperature inversion in the dayside atmosphere of HD 149026b. The best-fit model favors large amounts of CO and CO2, moderate heat redistribution (f = 0.5), and a strongly enhanced metallicity. These analyses use BiLinearly-Interpolated Subpixel Sensitivity (BLISS) mapping and parameter orthogonalization. The former is a new technique to model two position-dependent systematics, intrapixel variability and pixelation. The latter is a technique that accelerates the convergence of Markov chains that employ the Metropolis random walk sampler.Chapter 4 reports on the detection of GJ 436c, a 0.65 +/- 0.04 Earth-radii exoplanet transiting a nearby M-dwarf star with a period of 1.365862 +/- 8x10^{-6} days. It also presents evidence for a similarly sized exoplanet candidate (currently labeled UCF-1.02) orbiting the same star with an undetermined period. Assuming an Earth-like density of 5.515 g/cm^{3}, GJ 436c has a predicted mass of 0.28 Earth-masses (2.6 Mars-masses) and a surface gravity of 0.65 g (where g is the gravity on Earth). Its weak gravitational field and close proximity to its host star imply that GJ 436c is unlikely to have retained its original atmosphere; however, a transient atmosphere is possible if recent impacts or tidal heating were to supply volatiles to the surface. Chapter 5 presents numerical simulations of the GJ 436 system using the Mercury N-body integrator and detailed calculations used to constrain the atmospheric composition of the sub-Earth-sized planet GJ 436c. The simulations find a ~35-year periodic trend in the osculating elements wherein GJ 436c's eccentricity varies between 0 and 0.21, its peak-to-trough inclination amplitude is 3.2 degrees, and transit-timing variations range from +/-200 to +/-3 minutes.

Show moreWomen with military experience are attending colleges and universities across the United States. It is important to understand how they describe their experiences as students and how their help-seeking behaviors impact their success (DiRamio (&) Jarvis, 2011; Baechtold (&) Da Sawal, 2009). Using Schlossberg's Adult Transition Theory (1981, 1984) as a framework, this qualitative phenomenological study explored the help-seeking behaviors of women student veterans. In addition, the events that caused them to seek help and the resources they utilized are described. The research questions were: (1) Does the prior military experience of women student veterans influence their willingness to seek help? (2) What are the events that cause women student veterans to seek help? And (3) What are the resources that women student veterans utilize? Using Smith, Flowers and Larkin's (2009) Interpretative Phenomenological Analysis (IPA), this two-phase mixed method design employed a sequential descriptive strategy employing a profile questionnaire and individual semi-structured interviews (N=9). The research identified six themes using Schlossberg's framework (1981, 1984). These six themes were: military influence, transitions, times of distress, tailored support, traditional support and support 'from my own'. The findings of this study provide researchers, student personnel professionals, and military educational constituencies with a foundation for policy and programming that account for the help seeking behaviors women student veterans' exhibit as they transition from the military to college.

The thesis starts with a brief general introduction to the physics of quantum transport through single electron transistors. Afterwards, the main body of the thesis is divided into three studies: (i) In chapter (2) we describe the properties of single molecule magnets and the Berry phase interference present in this nanomagnets. We then propose a way to detect quantum interference experimentally in the current of a single molecule magnet transistor using polarized leads. We apply our theoretical results to the newly synthesized nanomagnet Ni4. (ii) In chapter (3) we review the Kondo effect and present a microscopic derivation of the Kondo Hamiltonian suitable for full and half integer spin nanomagnets. We then calculate the conductance of the single molecule magnet transistor in the presence of the Kondo effect for Ni4 and show how the Berry phase interference becomes temperature dependent. (iii) We conclude in chapter (4) with a theoretical study of the single Nitrogen vacancy defect center in diamond. We show that it is possible to have spin non-conserving transitions via the hyperfine interaction and propose a way to write and read quantum information using circularly polarized light by means of optical Lambda transitions in this solid state system.

Title: A New Methodology for Evaluating the Effectiveness of Bus Rapid Transit Strategies.
Creator: Alomari, Ahmad, Al-Deek, Haitham, Eluru, Naveen, Tatari, Omer, Maboudou, Edgard, University of Central Florida
Abstract / Description: Over the last few years, public transportation has become more desirable as capacity of existing roadways failed to keep up with rapidly increasing traffic demand.

Show moreOver the last few years, public transportation has become more desirable as capacity of existing roadways failed to keep up with rapidly increasing traffic demand. Buses are one of the most common modes of public transportation with low impact on network capacity, especially in small and congested urban areas. However, the use of regularly scheduled buses as the main public transport mode can become useless with the presence of traffic congestion and dense construction areas. In cases like these, innovative solutions, such as bus rapid transit (BRT), can provide an increased level of service without having to resort to other, more expensive modes, such as light rail transit (LRT) and metro systems (subways). Transit signal priority (TSP), which provides priority to approaching buses at signalized intersections by extending the green or truncating the red, can also increase the performance of the bus service.Understanding the combined impact of TSP and BRT on network traffic operations can be complex. Although TSP has been implemented worldwide, none of the previous studies have examined in depth the effects of using conditional and unconditional TSP strategies with a BRT system. The objective of this research is to evaluate the effectiveness of BRT without TSP, then with conditional or unconditional TSP strategies. The micro-simulation software VISSIM was used to compare different TSP and BRT scenarios. These simulation scenarios include the base scenario (before implementation of the TSP and BRT systems), Unconditional TSP (TSP activates for all buses), Conditional TSP 3 minutes behind (TSP only activates for buses that are 3 minutes or more behind schedule), Conditional TSP 5 minutes behind (only activates for buses 5 minutes or more behind schedule), BRT with no TSP, BRT with Unconditional TSP, BRT with Conditional TSP 3 minutes behind, and BRT with Conditional TSP 5 minutes behind.The VISSIM simulation model was developed, calibrated and validated using a variety of data that was collected in the field. These data included geometric data, (number of lanes, intersection geometries, etc.); traffic data (average daily traffic volumes at major intersections, turning movement percentages at intersections, heavy vehicle percentages, bus passenger data, etc.); and traffic control data (signal types, timings and phasings, split history, etc.). Using this field data ensured the simulation model was sufficient for modeling the test corridor. From this model, the main performance parameters (for all vehicles and for buses only) for through movements in both directions (eastbound and westbound) along the corridor were analyzed for the various BRT/TSP scenarios. These parameters included average travel times, average speed profiles, average delays, and average number of stops. As part of a holistic approach, the effects of BRT and TSP on crossing street delay were also evaluated. Simulation results showed that TSP and BRT scenarios were effective in reducing travel times (up to 26 %) and delays (up to 64%), as well as increasing the speed (up to 47%), compared to the base scenario. The most effective scenarios were achieved by combining BRT and TSP. Results also showed that BRT with Conditional TSP 3 minutes behind significantly improved travel times (17 (-) 26%), average speed (30 (-) 39%), and average total delay per vehicle (11 (-) 32%) for the main corridor through movements compared with the base scenario, with only minor effects on crossing street delays. BRT with Unconditional TSP resulted in significant crossing street delays, especially at major intersections with high traffic demand, which indicates that this scenario is impractical for implementation in the corridor. Additionally, BRT with Conditional TSP 3 minutes behind had better travel time savings than BRT with Conditional TSP 5 minutes behind for both travel directions, making this the most beneficial scenario.This research provided an innovative approach by using nested sets (hierarchical design) of TSP and BRT combination scenarios. Coupled with microscopic simulation, nested sets in the hierarchical design are used to evaluate the effectiveness of BRT without TSP, then with conditional or unconditional TSP strategies. The robust methodology developed in this research can be applied to any corridor to understand the combined TSP and BRT effects on traffic performance. Presenting the results in an organized fashion like this can be helpful in decision making. This research investigated the effects of BRT along I-Drive corridor (before and after conditions) at the intersection level. Intersection analysis demonstrated based on real life data for the before and after the construction of BRT using the Highway Capacity SoftwareTM (HCS2010) that was built based on the Highway Capacity Manual (HCM 2010) procedures for urban streets and signalized intersections. The performance measure used in this analysis is the level of service (LOS) criteria which depends on the control delay (seconds per vehicle) for each approach and for the entire intersection. The results show that implementing BRT did not change the LOS. However, the control delay has improved at most of the intersections' approaches. The majority of intersections operated with an overall LOS "C" or better except for Kirkman Road intersection (T2) with LOS "E" because it has the highest traffic volumes before and after BRT construction.This research also used regression analysis to observe the effect of the tested scenarios analyzed in VISSIM software compared to the No TSP (-) No BRT base model for all vehicles and for buses only. The developed regression model can predict the effect of each scenario on each studied Measures of Performance (MOE). Minitab statistical software was used to conduct this multiple regression analysis. The developed models with real life data input are able to predict how proposed enhancements change the studied MOEs. The BRT models presented in this research can be used for further sensitivity analysis on a larger regional network in the upcoming regional expansion of the transit system in Central Florida. Since this research demonstrated the operational functionality and effectiveness of BRT and TSP systems in this critical corridor in Central Florida, these systems' accomplishments can be expanded throughout the state of Florida to provide greater benefits to transit passengers. Furthermore, to demonstrate the methodology developed in this research, it is applied to a test corridor along International Drive (I-Drive) in Orlando, Florida. This corridor is key for regional economic prosperity of Central Florida and the novel approach developed in this dissertation can be expanded to other transit systems.

Show moreThis thesis explores the reasons behind the stagnation in the transition to democracy in Kazakhstan and Uzbekistan. According to their constitutions, Kazakhstan and Uzbekistan are democracies. In actuality, however, there is little evidence to support that these are democratic systems. These states' post-Soviet constitutions outline them as democracies – yet they lack a free press; freedom of association is suppressed; religious freedom is limited; and free speech is constrained as well. While these two countries hold popular elections, much of their electoral processes are under the control of the executive branch of government - calling into question whether or not Kazakhstan and Uzbekistan really hold "fair and competitive" elections. In sum, in both of these states, democracy is de jure rather than de facto. Why is this so? Why are Kazakhstan and Uzbekistan not the democracies in practice that they are on paper?Many scholars and policy-makers blame the stagnation in these states' democratic transitions on the firm hands used by the countries' presidents to maintain their current power and even to increase it. Other scholars point out that Central Asia has never been democratic and thus does not know how to be so. These scholars refer, in particular, to the region's history as part of the Russian Empire and later, as part of the Union of Soviet Socialist Republics (USSR). Using frameworks drawn from Dahl's Polyarchy (1971) and Huntington's The Third Wave (1991), this thesis finds that not only are Kazakhstan and Uzbekistan straying from their constitutional democratic starting points, no single factor is to blame for the stagnation in the transitions to democracy in Kazakhstan and Uzbekistan. Rather, it is the combination of multiple factors – both internal and external – that provides the most comprehensive explanation of these states' failure to become full-fledged democracies. Combining the elements of strong dictator-like presidents with a lack of democratic history is but the tip of the iceberg. Internal factors such as "political culture" and external factors such as the influence of the international community also play major roles in the current state of affairs in these Central Asian states.

Show moreThe structure of regional correlation graphs built from fMRI-derived data is frequently used in algorithms to automatically classify brain data. Transformation on the data is performed during pre-processing to remove irrelevant or inaccurate information to ensure that an accurate representation of the subject's resting-state connectivity is attained. Our research suggests and confirms that such pre-processed data still exhibits inherent transitivity, which is expected to obscure the true relationships between regions. This obfuscation prevents known solutions from developing an accurate understanding of a subject's functional connectivity. By removing correlative transitivity, connectivity between regions is made more specific and automated classification is expected to improve. The task of utilizing fMRI to automatically diagnose Attention Deficit/Hyperactivity Disorder was posed by the ADHD-200 Consortium in a competition to draw in researchers and new ideas from outside of the neuroimaging discipline. Researchers have since worked with the competition dataset to produce ever-increasing detection rates. Our approach was empirically tested with a known solution to this problem to compare processing of treated and untreated data, and the detection rates were shown to improve in all cases with a weighted average increase of 5.88%.

Show moreThe Arab Spring that began in Tunisia and spread throughout the Middle East shook the region. These populous movements unseated authoritarian rulers whose power and position were well entrenched, potentially setting numerous countries on a path towards democratization. This project seeks to explain why the democratic transitions within the countries of Egypt, Tunisia, and Yemen have been largely unsuccessful. The large amounts of literature that flooded the academic forums through articles and books are analyzed, providing numerous explanations as to why these transitions have been unsuccessful such as polarization, deadlock, sectarianism, violence, and institutional conflict. This literature focuses on either one or several of the above-mentioned explanations while not pinning down a central cause for these phenomena, since they are all present in all three cases. This paper asserts that the cause of this hindered transition is the emphasis that these States placed upon electoral democracy. An emphasis placed on elections during transition highlighted and exacerbated factors (polarization, deadlock, sectarianism, violence, and institutional conflict) already present in these societies but kept dormant under authoritarian rule. To illustrate this the initial transitional government, representative body elected, and executive is analyzed to show how each governing unit stressed elections before a constitution. The identification of an overarching cause for the lack of fruitful transition like this project seeks to accomplish is of great importance, filling a much needed gap in the literature of comparative Middle Eastern revolutionary studies; along with providing foreign policy makers a tool to craft more impactful policy.

Show moreExamining diversity over multiple spatial and temporal scales affords the opportunity to develop a mechanistic understanding of the factors influencing community diversity dynamics, and how these may shift in a changing world. This thesis first examines multi-decadal fish community diversity metrics across a coastal biogeographic transition zone to quantify changes in species assemblages, assess relationships between fish community diversity and the abiotic environment, and capture potential shifts in the location of a putative biogeographic break. Results of this chapter indicate not only a change in fish community composition, but also a shift in the location of the biogeographic transition zone. If these trends continue, a potential 16-62km shift northward by the year 2100 could occur. Understanding the novel species assemblages these shifts could result in is necessary for the future management of this area. Next this thesis examines diversity on a local scale, assessing the response of the fish community to restoration of oyster reefs and coastal wetlands which act as essential fish habitat. Results support the idea that fish community composition at restored oyster reefs is more similar to those of live reefs than dead reefs, however, results of abundance and diversity analyses were equivocal. Living shoreline analyses produced no differences between control and restored sites before or after restoration. Possible explanations for lack of clear trends in the fish community could be explained by the presence of other essential fish habitats in the area, scale of restoration, and length of monitoring. This thesis explores diversity on a multitude of spatial and temporal scales to better understand how fish communities respond to change and generates fundamental knowledge that can improve our ability to conserve and manage coastal communities and better inform the development of ecosystem-based management strategies.

Show moreProstate cancer is the most common cancer in men in the western world. Although early stage prostate cancer is treatable late stage, more specifically, metastatic and drug resistant prostate cancers are mostly incurable. The failure of current treatments obligates the research community to explore novel areas in prostate cancer biology and find better therapeutic targets. Emerging evidences show that non-coding RNAs specifically long non-coding RNAs (lncRNAs) play regulatory roles in various cellular processes and are frequently dysregulated in cancer including prostate cancer. These aberrantly expressed lncRNAs mostly with unexplored genetic information may drive cancer progression. Previous studies done in our laboratory showed a tumor suppressor role of a cluster of small non-coding RNAs or microRNA (miRNA) miR-17-92a in PC-3 prostate cancer cells. To learn the underlying mechanism, transcriptome analysis with or without expression of miR-17-92a was conducted in our laboratory. RNA-sequencing data analysis identified reduced expression of a set of lncRNAs and oncogenes, and up regulation of several tumor suppressor genes upon expression of miR-17-92a cluster miRNAs. One of the down regulated intergenic lncRNAs, PAINT (Prostate Cancer Associated Intergenic Non-coding Transcript) (LINC00888), was selected for determining its functional role in prostate cancer. TCGA and GEO profiles analyses revealed up regulation of PAINT in prostate tumors with higher Gleason Scores, in highly aggressive metastatic prostate cancer cell lines, and upon androgen deprivation therapy of prostate cancer cells. This observation was supported by our studies on expression analysis of PAINT in prostate tumor tissues using RNA in-situ hybridization in tissue microarrays (TMA) containing tissues from different stages of prostate cancer and normal prostate tissues, which showed higher expression of PAINT in prostate cancer tissues compared to normal tissues. Furthermore, late stage (stage III and stage IV) prostate tumors showed significant overexpression of PAINT compared to early stage (stage II) prostate cancer tissues. We examined the functional relevance of PAINT in promoting tumor progression next using different prostate cancer cell lines. Silencing of PAINT using siRNAs showed decreased cell proliferation, reduced S-phase progression and activation of pro-apoptotic proteins PARP and Caspase-3. Silencing of PAINT also showed decreased cell migration and increased expression of the epithelial marker, E-cadherin while reduced expression of mesenchymal markers Slug and Vimentin. Ectopic expression of PAINT reversed the effects observed upon silencing of PAINT. Increased cell proliferation, cell cycle progression and cell migration were noted in prostate cancer cells overexpressing PAINT. Additionally, cancer promoting phenotype such as larger colony formation and higher expression of mesenchymal marker Slug, was detected upon overexpression of PAINT. Our study also determined the therapeutic benefit of inhibition of expression showing an increased sensitivity of metastatic prostate cancer cells to the chemotherapeutic agent docetaxel (DTX) and selective Aurora kinase inhibitor VX-680. Taken together, our study establishes an oncogenic function of PAINT, its clinical relevance as a marker for advanced stage prostate cancer and its potential as a therapeutic target for metastatic prostate cancer.

Show moreWith the ever growing number of proposed desnity functional theory (DFT) functionals it becomes necessary to thoroughly screen any new method to determine its merit. Especially relevant methods include a proper description of the van der Waals (vdW) interaction, which can prove vital to a correct description of a myriad of systems of technological importance. The first part of this dissertation explores the utility of several vdW-inclusive DFT functionals including optB86b-vdW, optB88-vdW, optPBE-vdW, revPBE-vdW, rPW86-vdW2, and SCAN+rVV10 by applying them to model systems of small organic molecules, pyridine and thiophene, on transition metal surfaces. Overall, we find the optB88-vdW functional gives the best, most balanced description of both thiophene and pyridine on transition metal surfaces while revPBE-vdW, rPW86-vdW2, and SCAN+rVV10 functionals perform especially poorly for these systems. In the second part of this dissertation we change our focus to potential applications of DFT. Specifically, we study the hydrodesulfurization (HDS) process and molecules that could be used in molecular electronics. The removal of sulfur containing molecules from petrochemicals through HDS is an exceptionally important process economically, and the field of molecular electronics is rapidly developing with hopes of competing with and replacing their silicon analogues. First we investigate the hydrodesulfurization of thiophene. In this dissertation we manage to map the HDS rate of thiophene in realistic reaction conditions to the charge transfer and adsorption energy of thiophene on bare transition metal surfaces in hopes of predicting ever more active HDS catalysis. Finally we look at the adsorption of polythiophenes and 5,14-dihydro-5,7,12,14-tetraazapentacene (DHTAP) on Au(111) and Cu(110). We find that polythiophenes may dissociate of Au(111), presenting an issue for their use in molecular electronics. DHTAP, in contrast, proves to a suitable candidate for use practical devices.

Show moreThe purpose of this phenomenological inquiry was to explore how international undergraduate students enrolled in a first-year seminar (FYS) course perceived and described their academic experiences in a large, public university in the southeastern region of the United States. Guided by Schlossberg's (1984) 4 S Transition Model, this qualitative investigation was conducted through in-depth interviews with 10 international undergraduate students representing different countries and academic majors. The participants' narratives revealed that the academic experiences of international first-year students enrolled in the FYS course can be described as challenging, especially in terms of a) understanding U.S. higher education, b) establishing relationships with American peers, c) navigating academic differences, and d) perceiving the lack of institutional understanding. At the same time, the stories of these 10 students demonstrated that participation in the FYS course had an overall positive impact on students' academic experiences during the first year, especially in terms of a) developing academic skills and competencies, b) developing transferable skills and competencies, c) increased use of campus resources, and d) overall adjustment within the first year. The findings are discussed in relation to the relevant literature and recommendations for practice and future research are provided.

Show moreThe purpose of the current study was to examine whether older job applicants are discriminated against relative to younger job applicants when changing careers, and to investigate whether an intervention designed to reduce stereotyping and prejudice could alleviate such unfair discrimination, if it was found. A between-subjects laboratory experiment with three factors was conducted, including age (young vs. old job applicant), career-transition type (within- vs. between-career transition), and a dual-identity based recategorization intervention (control vs. intervention), totaling 8 experimental conditions. Data were collected and analyzed from 157 undergraduate student participants. Participants were informed that they would be evaluating the viability of using video-resumes as a potential organizational selection tool, and were randomly assigned to watch a video-resume depicting a White male job applicant applying for the job of mechanical engineer. The job applicant was either younger or older and was either making a career change that was more similar to his previous career (i.e., naval architect) or less similar to his previous career (i.e., chiropractor). In the intervention conditions, the job applicant emphasized his age and the fact that he graduated from UCF; in the control conditions, he only emphasized his age and his educational background from a generic university. An actor in his early twenties played the role of the job applicant. Make-up was applied to age his face, and computer software was used to age his voice. After viewing the video-resumes, participants judged his suitability for hire, competence, warmth, loyalty, and suitability for training. A Multivariate Analysis of Covariance (MANCOVA) was conducted and a significant 3-way interaction was found between age, career-transition type, and intervention on both ratings of suitability for hire and on competence ratings. Counter to theory, the older job applicant was negatively impacted relative to the younger applicant when attempting to build a common ingroup identity with the younger decision-maker. These findings were discussed within the context of theories on attribution and impression management, and discussed relative to prior research utilizing the dual-identity based recategorization intervention method. Implications for older workers making career transitions are discussed.

Show morePolicy makers are considering several alternatives to counter the negative externalities of personal vehicle dependence. Towards this end, public transit investments are critical in growing urban regions such as Orlando, Florida. Transit system managers and planners mostly rely on statistical models to identify the factors that affect ridership as well as quantifying the magnitude of the impact on the society. These models provide vital feedback to agencies on the benefits of public transit investments which in turn act as lessons to improve the investment process. We contribute to public transit literature by addressing several methodological challenges for transit ridership modeling. Frist, we examine the impact of new transit investments (such as an addition of commuter rail to an urban region) on existing transit infrastructure (such as the traditional bus service already present in the urban region). The process of evaluating the impact of new investments on existing public transit requires a comprehensive analysis of the before and after measures of public transit usage in the region. Second, we accommodate for the presence of common unobserved factors associated with spatial factors by developing a spatial panel model using stop level public transit boarding and alighting data. Third, we contribute to literature on transit ridership by considering daily boarding and alighting data from a recently launched commuter rail system (SunRail). The model system developed will allow us to predict ridership for existing stations in the future as well as potential ridership for future expansion sites. Fourth, we accommodate for potential endogeneity between bus headway and ridership by proposing a simultaneous model system of headway and ridership. Finally, a cost benefit analysis exercise is conducted for examining the impact of Sunrail on the region.

Show moreThe collaborative efforts of families, educators, and policy makers have mergedvocational training with special education services for students with disabilities. The Individuals with Disabilities Education Act of 2004 introduced mandates for schools to provide transition services for students with disabilities based on three areas of need: a) education, b) employment,and independent living. This legislation has led to more work-based learning programs that meet the postsecondary needs for students with disabilities. Despite this increase in work-based learning programs many students with disabilities are still unable to make successful transitions into postsecondary outcomes. Using a mixed method design, this study examined the impact of a Job Experience Training (JET) program on the executive functioning skills of seven young men (15 to 18 years of age) over the course of seven weeks at an assisted living facility. Resultsof the teacher evaluations showed the students were capable of completing tasks, making individual goals, and increasing executive functioning skills while participating in the JET program. Conversely, the results from the parent and student assessments showed little to no change in executive functioning skills once the participants were outside the context of theassisted living facility. Future research is encouraged to examine a longitudinal study across multiple job sites that evaluates and measures the students' ability to transfer executive functioning skills to other contexts and further investigate mentoring as the core teaching strategy of a JET program.

Show moreFor all business organizations, there comes a time when a change must take place within their eco-system. It consumes a great deal of thought and planning to ensure that the right decision is made as it could alter the entire course of their business for a number of years to come. This change may appear in the form of a brilliant CEO reaching the age of retirement, or an unsuccessful Managing Director being asked to leave before fulfilling the term of her contract. Regardless of the cause, a transition must occur in which a suitable successor is chosen and put into place while minimizing costs, satisfying stakeholders, ensuring that the successor has been adequately prepared for their new position, and minimizing work place gossip, among other things. It is also important to understand how the nature of the business, as well as its financial standing, effects such a transition.Engineering and management principles come together in this study to ensure that organizations going through such a change are on the right course. As the problem of transitional management is not one of concrete values and contains many ambiguous concepts, one way to tackle the problem is by utilizing various industrial engineering methodologies that allow these companies to systematically begin preparing for such a change. By default, organizational strategy has to change, technology is continually being renewed and it becomes very hard for the same leader to constantly implement new and innovative developments.Organizations today have a very poor understanding of where they currently stand and as a result the cause for a company's lack of profitability is often overlooked with time and money being wasted in an attempt to fix something that is not broken. To be able to look at the bigger picture of an organization and from there begin to close in on the main problems causing a negative impact, the Matrix of Change is used and takes in many factors to layout an accurate representation of the direction in which an organization should be headed and how it can continue to grow and remain successful. The Theory of Constraints on the other hand is used here as a step-by-step guide allowing companies to be better organized during times of change. And System Dynamics modeling is where these companies can begin to simulate and solve the dilemma of transitional management using causal loop diagrams and stock and flow diagrams.Through such tools a framework can begin to be developed, one that is valued by corporations and continually reviewed. Several case studies, simulation modeling, and a panel of experts were used in order to demonstrate and validate this framework.

Show moreBorides are implemented in a range of industrial applications due to their unique mechanical, electrical, thermal and catalytic properties. In particular, transition metal diborides are of special interest. In the recent years, borides of rhenium (Re), osmium (Os) and iridium (Ir) have been studied as for their ultra-hardness and superior stiffness. In this dissertation, a mechanochemical method is introduced to produce rhenium diboride (ReB2) powder, a novel hexagonal osmium diboride (h-OsB2), and iridium boride powders. Densification by Spark Plasma Sintering (SPS), thermal stability and mechanical properties of h-OsB2 were also studied. ReB2 was recently reported to exhibit high hardness and low compressibility, which both are strong functions of its stoichiometry, namely Re to B ratio. Most of the techniques used for ReB2 synthesis reported 1:2.5 Re to B ratio because of the loss of the B during high temperature synthesis. However, as a result of B excess, the amorphous boron, located along the grain boundaries of polycrystalline ReB2, would degrade the ReB2 properties. Therefore, techniques which could allow synthesizing the stoichiometric ReB2 preferably at room temperature are in high demand. ReB2 powder was synthesized at low temperature using mechanochemical route by milling elemental crystalline Re and amorphous B powders in the SPEX 8000 high energy ball mill for 80 hours. The formation of boron and perrhenic acids are also reported after ReB2 powder was exposed to the moist air environment for a twelve month period of time.Hexagonal osmium diboride (h-OsB2), a theoretically predicted high-pressure phase, has been synthesized for the first time by a mechanochemical method, i.e., high energy ball milling. X-ray diffraction (XRD) indicated the formation of h-OsB2 after 2.5 hours of milling, and the reaction reaches equilibrium after 18 hours of milling. The lattice parameters of the h-OsB2 are a=2.916(&)#197; and c=7.376 (&)#197;, with a P63/mmc space group. Transmission electron microscopy confirmed the appearance of the h-OsB2 phase. The thermal stability of h-OsB2 powder was studied by heating under argon up to 876 (&)deg;C and cooling in vacuo down to -225 (&)deg;C. The oxidation mechanism of h-OsB2 has also been proposed. The hexagonal phase partially converted to the orthorhombic phase (20 wt.%) after spark plasma sintering of h-OsB2 at 1500(&)deg;C and 50MPa for 5 minutes. Hardness and Young's modulus of the h-OsB2 were measured to be 31 (&)#177; 9 GPa and 574 (&)#177; 112 GPa, respectively by nanoindentation method.Prior to this research a number of compounds have been prepared in Ir-B system with lower than 2 boron stoichiometry, and no IrB2 phases have been synthesized experimentally. In this dissertation, three new iridium boride phases, ReB2-type IrB2, AlB2-type IrB2 and IrB have been synthesized with a similar mechanochemical method. The formation of these three phases has been confirmed by both X-ray diffraction (XRD) and transmission electron microscope (TEM) after 30 hours of ball milling and 48 hours of annealing. The IrB2 phases have hexagonal crystal structures and the new IrB phase has an orthorhombic crystal structure. The segregation of iridium from iridium borides' lattices has also been studied by high resolution TEM.

Show moreThis phenomenological study addressed the transitions of biology and chemistry adjunct faculty, with full or part-time positions outside of academia, as they navigate the transition between their workplaces and the academic environment and also transition toward becoming confident and competent educators. Using the final two stages of Schoening's (2013) Nurse Educator Transition (NET) Model as a framework, this qualitative study examines the transitions of nine biology and chemistry adjuncts at College Alpha, which is a community college located in a southern state. Study findings indicated both degrees of transition, the day-to-day and the overall transition into teaching, impact the overall adjunct experience. The College's involvement with the adjunct and the generational differences between the adjuncts and their students also play a role in the transitions. The literature review addressed the use of the NET Model as a means of examining transitions toward teaching, the roles of adjunct faculty on college campuses, the workplace transition, and the particular needs of Millennial students are also addressed. The study culminated with conclusions about the experiences of the participants, recommendations for future research, and calls for action by community colleges to improve the adjunct experience. A chapter is also included that reflects upon the dissertation writing experience and the challenges of qualitative research not addressed in graduate programs.

Show moreResearch in writing studies has focused on students who make the traditional transition from high school to first year composition, to the entry level discipline specific courses in their chosen majors (Wardle, 2007, 2009; Sommers and Saltz, 2004; Beaufort, 2007; Carroll, 2002). Very little scholarship addresses those students who (")skip(") first year composition and find themselves in entry level discipline specific courses classrooms. With three former students, I conduct a case study over the course of eight months via a series of face to face, facetime, skype and email interviews. Each of these students, through earning high test scores in high school, forego first year composition and move directly to entry level discipline specific courses. Using third generation activity theory as a lens (Engestr(&)#246;m, 1996, 1999, 2001; Roth and Lee, 2007; Russell, 1995, 1997; Kain and Wardle, 2002), I examine these students' understanding of what they have experienced in high school writing(-)specifically high school English class(-)what they think college writing will demand, and finally what, in fact, they find the college writing demands to be. Not only do I find that each of the students felt very prepared for the demands they will encounter, but they remained confident. The study does, however, illuminate unforeseen challenges for both students and those who teach them: student literate lives are incredibly complex, and there is a real potential for a writing gap between formal writing instruction and when students will engage in intensive discipline writing tasks.
