This study draws from the social reproduction theory of Pierre Bourdieu, in particular Bourdieu's concept of habitus, in an attempt to uncover the means by which California community college students are channeled into particular transfer destinations, specifically, the California State University, the University of California, and four-year for-profit universities such as the University of Phoenix. Bourdieu's concept of habitus, operationalized in this study as ascribed characteristics of students, such as ethnicity, class, and gender, and organizational qualities of the community college, such as transfer rates, percentages of students receiving need-based aid and requiring remedial coursework, were examined in an effort to discern the effects of social background characteristics, academic experiences, and institutional effects in the transfer process. Multinomial logistic regression analysis was used to ascertain the predictive value and relative strength of each of the variables in the model. In addition, the relative risk ratios for three distinct contrasts were estimated. The risk ratios associated with the set of social, academic, and organizational qualities on transfer to the CSU were compared with those associated with transfer to the University of California and for-profit universities. Predicted probabilities, based upon ethnicity and financial need, of attending the most selective institution (i.e. the University of California) were also calculated. This procedure allowed for certain characteristics, such as full or part-time attendance or academic area of emphasis, to be held constant thus illuminating the effects of such variables as race, gender, and the transfer rate of the community college. For the total population of community college students, social background, academic experiences, and organizational characteristics had predictive effects on the transfer outcome. Specifically, the strongest predictors of transfer to the University of California were GPA, being Asian, and the transfer rate of the community college. Age exerted the strongest negative effect on transfer to the University of California. The strongest predictors of transfer to the for-profit segment were age, part-time attendance at the community college, being African American, and male. GPA exerted the strongest negative effect relative to the other predictors on transfer to the for-profit segment. For the total population of community college students, Asian males and females had the highest predicted probabilities of transfer to the UC while African American males and females had the highest predicted probabilities of transfer to the for-profit segment. For the traditional group of community college students, Asian males and females had the highest predicted probabilities of transfer to the University of California and Latino males and females had higher predicted probabilities of transfer to the University of California than white students. For the entire population of community college students, the transfer rate of the community college had no impact on the predicted probabilities of transfer to particular institutions; however, consistent with previous community college research, for the traditional subset of community college students, the transfer rate of the community college exerted a positive effect on transfer. Specifically, the predicted probability of transfer to the University of California was higher when students were enrolled at community colleges with higher transfer rates.

Focusing on the social network processes of social capital and social cohesion, this dissertation explores how a parent's social ties and beliefs influence parent involvement at home and at school. In addition, to network factors, this study examined individual influences on parent involvement including a parent's sense of efficacy to help his or her child with school and the degree to which he or she believes all parents should be involved in their own child's education. A theoretical framework was created arguing social networks affect parent involvement through the network processes of social cohesion and social capital. In the first case, social cohesion, parents are embedded in a subgroup of other parents where they share and compare their beliefs about parent involvement. Social capital involves a parent's investment of resources into another parent or the school, and was expected to affect parent involvement at home and at school. The investment of resources into one another enable parents to become more involved at home and at school. The investment of resources toward the school, on the other hand, affect parent involvement at school through the development of a sense of obligation. In order to study social network processes and parental beliefs as predictors of parent involvement, survey and interview data were collected at two elementary schools. Using this data, network maps of parent-parent relationships were created and used to identify subgroups. Parents' beliefs and network characteristics, as well as subgroup characteristics, were examined as predictors of parent involvement at home and at school. Finally, interviews were conducted to obtain qualitative data about how social capital and social cohesion function toward the creation of parent involvement. Data analyses showed evidence that social cohesion and social capital were influences on parent involvement. The data also indicate that parental beliefs were predictors of parent involvement. Further support for the theoretical framework guiding this dissertation was obtained from interviews with parents. The results of this study suggest that, in addition to parental beliefs, a parent's social network provide her or him with resources which facilitate parent involvement. In the end, this dissertation argues for researchers of parent involvement to look beyond the individual parent and to begin to consider social ties and social networks as important influences on parents' behaviors.

The main objective of this document is to investigate the suitability and aptness of performing the solo piano music of Franz Liszt (1811--1886) on the harp. This has been accomplished by dividing Liszt's career into four periods and examining the various connections he retained with harpists with during each of these periods. For each of these harpists the author shows how they became associated with Liszt, the scope of their work together, and demonstrates their influence on his life and compositional style, including musical examples where appropriate. As part of this research project the author also offers four of her own transcriptions of Liszt's solo piano compositions, corresponding from each of the four life stages, explaining why these are idiomatic for performance on the harp. This document also examines and explains any changes made from the original to the transcription with the inclusion of musical examples. These transcriptions, included in the document as appendices, are ready for publication and will hopefully become valuable additions to the harp repertoire.

My objective in this project is to draw attention to the frequency with which the figure of the child appears in representations of catastrophe and to map out the causes and consequences of that association. The Rhetoric of Future Harm is thus a rhetorical and tropological study of the child as a figure in contemporary discourse. In what follows, I will propose that the child-figure condenses fears about the human future. A longstanding figure in American culture, the child in contemporary representations of catastrophe, I contend, captures and contains the energies of change, transforming them into anxious fantasies of harm. In particular, I look at representations and rhetorics that bring the child's economy of meanings to bear on the threatened human future. I argue that the deep and pervasive anxiety about the future of the human discloses the apprehension of complexity. I find in this apprehension the nascent recognition of further futures and new forms for a (post)-humanity and a post-humanism. The child-figure is thus a deeply ambivalent attempt to harness, capture and control, the movements of the future and the meanings of life-itself. The Rhetoric of Future Harm investigates four intensively invested sites where life-itself takes the face of the child: the rhetoric of urgency employed by popular environmentalism; the individuation of life characteristic of rescue narratives and reproductive futurism; the sacralization of the human world in post-apocalypses and the cultivation of regimes of meaning in literary theory. The middle two chapters, "Rescue and Reproductive Futurism" and "Redemptive Catastrophes and Metaphysical Materialisms" conduct close studies of single novels, Joanna Russ's feminist SF novel We Who Are About To... (1973) in the second chapter and Cormac McCarthy's postapocalyptic The Road (2006) in the third. Taken together these chapters represent a sustained investigation of the metaphysics of the child under conditions of ecological threat. The first and last chapters, "Eco-Catastrophe and the Queer Matter of the Future" and "Life Matters Beyond the Child," look at the distributions of the rhetoric of the child in non-fictional discursive domains.

Low-conductivity media are found in a vast number of applications, for example as electrical insulation or as the matrix polymer in high strength-to-weight ratio structural composites. In some applications, these materials are subjected to extreme environmental, thermal, and mechanical conditions that can affect the material's desired performance. In a more general sense, a medium may be comprised of one or more layers with unknown material properties that may affect the desired performance of the entire structure. It is often, therefore, of great import to be able to characterize the material properties of these media for the purpose of estimating their future performance in a certain application. Low-conductivity media, or dielectrics, are poor electrical conductors and permit electromagnetic waves and static electric fields to pass through with minimal attenuation. The amount of electrical energy that may be stored (and lost) in these fields depends directly upon the material property, permittivity, which is generally complex, frequency-dependent and has a measurable effect on sensors designed to characterize dielectric media. In this work, two different types of dielectric sensors: radio frequency resonant antennas and lower-frequency (<1 MHz) capacitive sensors, are designed for permittivity characterization in their respective frequency regimes. In the first part of this work, the capability of characterizing multilayer dielectric structures is studied using a patch antenna, a type of antenna that is primarily designed for data communications in the microwave bands but has application in the field of nondestructive evaluation as well. Each configuration of a patch antenna has a single lowest resonant (dominant mode) frequency that is dependent upon the antenna's substrate material and geometry as well as the permittivity and geometry of exterior materials. Here, an extant forward model is validated using well-characterized microwave samples and a new method of resonant frequency and quality factor determination from measured data is presented. Excellent agreement between calculated and measured values of sensor resonant frequency was obtained for the samples studied. Agreement between calculated and measured quality factor was good in some cases but incurred the particular challenge of accurately quantifying multiple contributions to loss from the sensor structure itself, which at times dominates the contribution due to the sample material. Two later chapters describe the development of capacitive sensors to quantify the low-frequency changes in material permittivity due to environmental aging mechanisms. One embodiment involves the application of coplanar concentric interdigital electrode sensors for the purpose of investigating polymer-matrix degradation in glass-fiber composites due to isothermal aging. Samples of bismaleimide-matrix glass-fiber composites were aged at several high temperatures to induce thermal degradation and capacitive sensors were used to measure the sensor capacitance and dissipation factor, parameters that are directly proportional to the real and imaginary components of complex permittivity, respectively. It was shown that real permittivity and dissipation factor decreased with increasing aging temperature, a trend that was common to both interdigital sensor measurements and standard parallel plate electrode measurements. The second piece of work involves the development of cylindrical interdigital electrode sensors to characterize complex permittivity changes in wire insulation due to aging-related degradation. The sensor was proven effective in detecting changes in irradiated nuclear power plant wiring insulation and in aircraft wiring insulation due to liquid chemical immersion. In all three cases, the results indicate a clear correlation of measured capacitance and dissipation factor with increased degradation.

Strategies for the device integration and electrical characterization of individual colloidal semiconductor nanocrystals are presented. Results emphasize the insight gained by studying the electronic structure of individual nanocrystals as opposed to measurements of ensembles of particles. An analysis of a variety device geometries, material systems, and nanocrystal morphology and functionality shows that the method of electrical contact has a dominating role in the electrical behavior of the samples. Further, interactions with the electrode contact reflect the unique electronic and surface structure of the individual nanocrystals. In studies utilizing nanoscale lithography to directly deposit metal electrodes onto nanocrystals under vacuum, samples behave as single electron transistors (SET). Devices made from CdTe nanorods contacted by Pd display strong electron-electron correlations, which limit the flow of current to one electron at a time across the nanocrystal. Measurements also indicate that chemical reactions induced by the electrode metal cause diffusion of interface species and compositional modification of the nanoparticle. Interface chemical reactions may completely transform the nanocrystal under study, also altering the nanocrystal electronic structure. To avoid these complications, alternative strategies for device fabrication take advantage of the self-assembly of heterostructure nanoparticles. Synthetic methods for the direct solution-phase growth of Au electrodes on CdSe nanorod tips provide a 100,000-fold increase in the conductivity of single particles. Device response indicates ensemble electron physics and a Schottky barrier at the electrode contact, allowing quantitative determination of interface electronic structure. The methods of self-assembly are extended to a variety of heterostructure nanoparticles optimized for electronic and optoelectronic functionality. This work demonstrates the increasing sophistication of high-quality electrical devices achievable via self-assembly and verifies the process as an excellent route to the next generation of electronic and optoelectronic devices utilizing colloidal semiconductor nanocrystals.

The role of secondary special education teachers in assisting youth with disabilities access Supplemental Security Income (SSI) benefits was addressed in this study. Familiarity with the SSI program, involvement with the SSI program, and training preferences related to the SSI program were examined with a survey completed by 447 teachers. Four research questions were examined. First, to what extent are secondary special education teachers familiar and involved with the SSI program? Second, do their levels of familiarity and involvement differ based on demographic characteristics? Third, what reasons do they state for having no involvement with SSI? Finally, what training needs and preferences related to SSI do they have?. Results indicated that secondary special education teachers report little familiarity and little involvement with the SSI program. In particular, respondents reported little involvement in incorporating SSI issues into transition planning. Factor analyses resulted in retaining three factors: (a) Familiarity, (b) Involvement with Students, and (c) Reporting to Disability Determination Services. Teachers whose students' most common primary disability is mental retardation had higher familiarity scores than did other respondents. Teachers with 10 or more years of experience had higher Involvement with Students scores than did teachers with less than 10 years of experience. Teachers who have students who receive SSI benefits had higher Familiarity and Reporting to DDS scores than did teachers who did not know of any of their students receiving benefits. There were significant correlations between each pair of factors. Respondents reported a willingness to participate in training related to SSI and indicated that both parents and students need additional training on SSI issues. Respondents also provided suggestions the appropriate role of teachers and schools in assisting with SSI issues and expressed concerns about fraud and abuse, the complexities of the system, and the detrimental effects of SSI participation. Implications for future research, policy, and practice are discussed.

Spatial multiplexing for wireless communication systems is typically used at low GHz carrier frequencies in non Line-of-Sight environments. This dissertation considers adaptive spatial multiplexing for Line-of-Sight wireless links at millimeter-wave carrier frequencies. This architecture provides increased data capacity without increasing the channel bandwidth. The aggregate system data rate scales linearly with the number of transmitter and receiver antenna pairs. System theory and link sensitivity to non ideal installations, multipath signal propagation, and atmospheric refraction are considered. Channel separation hardware implementation considerations are analyzed. Initial work with a two-element prototype using IF channel separation is presented. This prototype achieved 1.2 Gb/s operation over a 6 m indoor link and similar performance for an outdoor link with a 41 m link range. A scalable baseband system architecture is proposed and demonstrated for an indoor link operating over a 5 m link range. The spatially multiplexed channels were separated at the receiver using broadband adaptive analog I/Q vector signal processing. A control loop continuously tuned the channel separation electronics to correct for changes with time in either the propagation environment or the system components. The four-channel 60 GHz hardware prototype achieved an aggregate system data rate of 2.4 Gb/s.
