The purpose of this work is to investigate local field type corrections to electrical transport properties and in particular small polaron hopping conductivity. The question of local field corrections to transport properties has been considered for some time. Recently this question has become of particular interest for small polaron hopping conduction. Such corrections were considered as a possible explanation for the large jump parameters inferred in fitting the electric field dependence of the electrical conductivity of certain transition metal oxide glasses in which conduction is believed to occur via thermally activated small polaron hopping. Local field corrections are well established in determining the dielectric constant and optical properties at a single atomic site. Tessman et al have shown that the assumption of a normal Lorentz term gives excellent agreement between computed and measured polarizabilities in alkali halide crystals at optical frequencies. Adler has proved, using a self-consistent field theory that the standard Lorentz term arises in the tight binding limit. Also a full quantum mechanical treatment of the frequency and wave-number dependent dielectric constant including local field effect has been given by Wiser. It is shown that the dielectric constant splits into an atomic term that describes the motion of the electron around each atom and an acceleration term which describes the motion from atom to atom and that acceleration term contains no local field correction. Lidiard has discussed Lorentz type corrections to the diffusion coefficient in ionic conductivity. He argued that no Lorentz correction should be applied, since the Lorentz cavity must always be centred on the hopping carrier; thus, the Lorentz internal field can do no work as the carrier moves from one site to another. This view is strongly supported by the close agreement between ionic diffusion coefficients obtained from conductivity data and NMR relaxation and isotopic diffusion. It has been argued by Munn in several papers without detailed justification that the microscopic mobility does give the polaron velocity in terms of a local field. This argument is in conflict with that of Lidiard. However this question had not been considered explicitly for the case of electrical transport in the hopping limit. It is the intent of the present work to study the local field problem. In the first chapter we give a general description of the local electric field concept which is straight review. Chapters II and III are concerned with the question of local field corrections to the small polaron hopping conduction and the Hall mobility. In Chapter IV the results of Chapter II are applied to ac impurity hopping conduction. Finally in Chapter V we study the band motion of electrons using a theory of transport based on quantum mechanical principles.

Doctor of Philosophy / Curriculum and Instruction Programs / Frederick Burrack / This study examined the characteristics of the score study processes implemented by three collegiate wind band conductors. Participants engaged in anticipatory discussion, think-aloud score study session, and a follow up interview to verify researcher inference and observation. Using a multiple case study methodology, the research focused on identifying the individual score study process of each conductor and the impact held beliefs and educational influences had on these processes. The research then compared cases to identify common and unique interactions across participants.

Chapter one of this thesis presents the literature pertaining to biological invasions and the different stages of invasions in terms of plant pathogens. The review focuses on determining areas where studying the population genetics of a pathogen might complement the knowledge of the ecology of the pathogen in order to gain a better understanding of their evolutionary and invasive potential. Dothistroma septosporum, which causes Dothistroma needle blight (DNB), is one of the better known examples of an invasive plant pathogen and is the focus of this thesis. After presenting an overview of the pathogen, it is concluded that a thorough knowledge of the ecological aspects of the pathogen has been gained by many intensive studies but that there is a distinct, and perhaps dangerous, lack of knowledge pertaining to the global population genetics of this pathogen. Throughout the years of this study, DNB has become a global concern as more epidemics were being reported, not only in the Southern Hemisphere where the disease has been problematic for over 50 years, but also in the Northern Hemisphere in both native and nonnative forests. An “International Dothistroma Alliance Committee” was established in 2004 among researchers world-wide with the aim being to share and integrate knowledge about the pathogen and the disease it causes. The main focus of this group incorporates aspects such as diagnostics and monitoring, assessing pathogen risk (pest-risk), disease impact, management and pathogen variability as well as population diversity. The research in this thesis greatly assists in the latter two aims of the committee. In the second chapter, multigene phylogenies were constructed from Dothistroma septosporum isolates obtained worldwide. These studies revealed that the disease is not caused by one pathogen with varying morphotypes, but that two, very closely related sibling species are responsible. A thorough description of the two species, named Dothistroma septosporum and D. pini, is provided. It is also shown in Chapter six that both species are capable of infecting the same needle and can co-exist within the same conidioma. There is thus a distinct potential for hybridisation to occur between these two species. Coincident with the initiation of this research is an increase globally in the incidence of DNB. This increased the knowledge base about the pathogens around the world and also made it easier to obtain cultures and isolates for this study from different sources. As a consequence, an understanding of the distribution and occurrence of each species was possible and is documented in Chapters three and six. The molecular techniques developed in this work have enabled the development of a robust technique to distinguish between the two pathogens causing DNB. A combination of the species-specific mating type markers designed by Groenewald et al. (2007), the diagnostic Primer_A, and an effective species-specific RFLP test, provide a quick and effective means of identifying the DNB pathogens, directly or indirectly, from conidiomata on infected needles. In order to study the population diversity of the DNB fungi, twelve microsatellite markers were developed in Chapter three. In Chapter four, the preliminary applications of these markers provide a first glimpse of the global diversity of D. septosporum which has caused the most devastation world-wide. From this research it is also obvious that the pattern of diversity reflects the movement of its host (pine) from its native Northern Hemisphere to various countries within the Southern Hemisphere. Dothistroma septosporum is an important disease of both plantation grown pines and native forests. Climate change and the continual movement of infected plant material pose great threats to existing forests. The fact that a sibling species has been discovered shows the evolutionary potential of the species to adapt to changing environments. Successful quarantine and monitoring will aid in curbing the further spread of the disease into areas where it could, potentially, be more devastating. The chapters in this thesis correspond to different research projects and are represented in the text in the format of a publication. Due to the nature of this style, however, there is some unavoidable repetition in the text, especially within the introduction of each chapter. Three of the chapters within this thesis have been published in internationally recognised ISI rated journals. / Thesis (PhD)--University of Pretoria, 2009. / Genetics / Unrestricted

This mixed methods study examines the lived experiences of six female high school band directors in the state of Florida as they related to the perceptions of the professional band association membership. This research focuses on how women and men perceive their experiences in relation to gender roles and gender-stereotyping in the traditionally masculine field of secondary instrumental music. A quantitative survey was distributed to the professional band association membership and 99 responses were recorded. Participants answered questions regarding years of teaching experience, grade levels taught, primary instrument, and their thoughts on the impact of gender on several aspects of instrumental music education. The survey results revealed that women feel strongly about the impact that gender has on instrument selection, performance opportunities, and job opportunities while men remain largely neutral. Out of the 99 responses, 6 participants that met the criteria for the qualitative interview portion of the study were contacted to arrange interviews / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

As the world continues to adopt the next generation of mobile technology, dual-band 5G wireless communications are becoming increasingly significant. 5G technology operates on two different frequency bands, the sub-6 GHz Frequency Range (FR1) and the millimeter wave (MMW) Frequency Range (FR2). The special features in each band enable 5G dual-band communication to provide better coverage and capacity than previous generations of wireless networks. This is especially essential for applications that need high-bandwidth and low-latency connections, such as virtual and augmented reality, autonomous vehicles, and industrial automation. Furthermore, dual-band 5G can help alleviate network congestion in urban areas by redirecting traffic to the MMW band, which has considerably greater capacity. As a result, dual-band 5G is expected to play a critical role in facilitating the next wave of technological innovation and revolutionizing the way we live and work. A dual-band antenna with a large frequency ratio (FR) is required due to the significant difference between each frequency band in 5G. Research on dual-band antennas is facing challenges such as low FR and a lack of a specific design methodology. Despite attempts to develop dual-band antennas with large FRs, there are still issues with low performance and limited bandwidth. This study introduces a novel approach for designing a dual-band antenna with a large FR. The proposed solution draws inspiration from a hybrid design of a dual-band antenna to achieve a large FR, and from the parabolic reflector antenna design to significantly enhance gain in the upper band. The lower band antenna in this design serves as both a radiator for the lower band and a reflector to align the beam in the upper band. This approach can be used to design dual-band antennas for various frequencies. In this thesis, we present a comprehensive model and framework for designing an antenna integrated reflector that offers a large FR. The proposed model is capable of producing an antenna that meets the requirements of the targeted application, namely 5G. This antenna exhibits wideband characteristics and high gain. Two different antenna integrated reflectors, named AIR-I and AIR-II, were designed based on the proposed model. AIR-I has a FR of 10.1. As for AIR-II, due to the presence of dual-band upper antennas, it has a lower band at 1.35 GHz and two upper bands at 13 GHz and 24 GHz thus, a FR of 9.5 and 18, respectively. The above design followed a specific purpose. It uses a 24 GHz/1.35 GHz frequency ratio of 18 to showcase the antenna performance in the context of dual-band 5G. However, the measurement facilities being limited to 20 GHz, a frequency ratio of 9.5 at 13 GHz/1.35 GHz was measured for the AIR-II, as proof of concept. Then, two prototypes were fabricated from AIR-II namely, Prototype-I and Prototype-II. While it would have been possible to demonstrate a proof of concept from a single prototype, it has been decided to produce and test two samples to enable a more exhaustive examination of the subject and obtain additional data that would lend greater support to the model outlined in this thesis. Prototype-I had the same structure as AIR-II and had an operational bandwidth of 0.69 GHz-1.74 GHz / 6 GHz-18 GHz and a FR of 9.9. On the other hand, Prototype-II had an operational bandwidth of 0.69 GHz-1.74 GHz / 13 GHz-18 GHz and a FR of 12.8. These prototypes exhibited maximum bandwidths of 100% and 86%, respectively. Furthermore, at the upper band, Prototype-I achieved a peak gain improvement of 12.6 dB, while Prototype-II achieved an improvement of 8.7 dB. These results demonstrated the significant advantages of our proposed methodology in dual-band antenna design.

The problem of this study was to make a transcription of the third movement of Dvorak's Symphony Number Five in E Minor from the "New World" for a class A symphonic band. A critical discussion of the musical and technical problems involved was included as a supplement or complement, as was a brief history of the composers life and works. In the arrangement of the data, the discussions were presented before the transcription might be readily understood.
