Description
Women's contributions to the history of Canadian music can be traced back to the late nineteenth century. However, women's achievements then, and still somewhat now, are often overlooked and as a result, piano solo works by Canadian women composers are largely unknown. The purpose of this study is to promote the wealth of solo piano repertoire composed by Canadian women, and to report the results in an accessible and comprehensible format for students, teachers, and performers at all levels. The research focuses on the most recent piano music by female composers born in or after 1950 whose compositions are available through the Canadian Music Centre (CMC) library. Brief biographies of included composers note their accomplishments, compositional output, and style characteristics. Annotations for the 103 works studied, written by twenty-six composers, include information about harmonic schemes, meters, tempos, durations, dates of the composition, CMC call number, level of difficulty, commissions, musical excerpts, premieres, and style characteristics. The style characteristics section includes composer's notes, technical challenges, musical characteristics, pedagogical values, and other pertinent information about a given piece. Since the goal of this project is to stimulate the awareness of music composed by Canadian women in a truly global sense, the research paper is supplemented by a website--www.canadianwomencomposers.com--that contains all the information found in the written portion of the annotations. This website also offers short audio samples of the compositions. The writer wishes to encourage all students, performers, and teachers to explore this resource, which reveals the richness of solo piano repertoire written by Canadian women composers.

Children with epilepsy represent a unique group of students who may require accommodations in school to be optimally successful. Therefore, it is important for teachers to understand the possible academic consequences epilepsy can have on a child. An important step in providing this information about epilepsy to teachers is understanding where they would prefer to acquire this information. The current study examined differences between teachers of differing ages, school levels and special education teaching status in their preferences for gaining information from parents and the internet. Contrary to expectations, older teachers (those 56 years of age and older) were no less likely that younger teachers to prefer information from the internet. As predicted, elementary school teachers were more likely than high school teachers to prefer information from parents. However, interestingly middle school teachers were also more likely to prefer information from parents than high school teachers. Lastly, contrary to hypothesized results, special education teachers were no more likely to prefer information from parents than non-special education colleagues. Limitations of this study, implications for practice and directions for future research are discussed.

Description
The purpose of my creative research was to analyze my choreographic process and answer the research question: how will implementing somatic principles impact my choreographic process? In determining the impact I analyzed the use of choreographic approaches that bring proprioceptive awareness to interdisciplinary somatic themes of bodily systems, sensing, connectivity, initiation and sequencing. These somatic themes were utilized in movement invention and exploration as well as the structuring and performance of my choreography. Additionally, the research involved clarifying my role as a choreographer and my relationship to the dancers in my work. My creative research occurred in three choreographic phases and resulted in the production of B.O.D.I.E.S performed in three consecutive sections titled Discovery, Exploration, and Identity November 5-7, 2010. B.O.D.I.E.S demonstrates how somatics will lead to greater movement possibilities and dynamic range to explore in the craft of dance making.

Description
It is estimated that wind induced soil transports more than 500 x 106 metric tons of fugitive dust annually. Soil erosion has negative effects on human health, the productivity of farms, and the quality of surface waters. A variety of different polymer stabilizers are available on the market for fugitive dust control. Most of these polymer stabilizers are expensive synthetic polymer products. Their adverse effects and expense usually limits their use. Biopolymers provide a potential alternative to synthetic polymers. They can provide dust abatement by encapsulating soil particles and creating a binding network throughout the treated area. This research into the effectiveness of biopolymers for fugitive dust control involved three phases. Phase I included proof of concept tests. Phase II included carrying out the tests in a wind tunnel. Phase III consisted of conducting the experiments in the field. Proof of concept tests showed that biopolymers have the potential to reduce soil erosion and fugitive dust transport. Wind tunnel tests on two candidate biopolymers, xanthan and chitosan, showed that there is a proportional relationship between biopolymer application rates and threshold wind velocities. The wind tunnel tests also showed that xanthan gum is more successful in the field than chitosan. The field tests showed that xanthan gum was effective at controlling soil erosion. However, the chitosan field data was inconsistent with the xanthan data and field data on bare soil.

Description
In this dissertation I present data gathered from an eleven-month qualitative research study with adolescents living and working on the streets of Lima, Peru. Through the pairing of photovoice with participant observations, this work incorporates distinctive methodological and theoretical viewpoints in order to complicate prevailing understandings of street life. In this dissertation, I examine the identities that children and adolescents on the street develop in context, and the ways in which photography can be a useful tool in understanding identity development among this population. Through a framework integrating theories of identity and identity performance with spatial theories, I outline how identity development among children and adolescents living on the street is directly connected to their relationships with the urban landscape and the outreach organizations that serve them. The organizations and institutions that surround children on the street shape who they are, how they are perceived by society, and how they view and understand themselves in context. It is through the interaction with aid organizations and the urban landscape that a street identity is learned and developed. Furthermore, as organizations, children and adolescents come together within the context of the city, a unique street space is created. I argue that identity and agency are directly tied to this space. I also present the street as a thirdspace of possibility, where children and adolescents are able to act out various aspects of the self that they would be unable to pursue otherwise. Weaved throughout this dissertation are non-traditional writing forms including narrative and critical personal narrative addressing my own experiences conducting this research, my impact on the research context, and how I understand the data gathered.

Description
The Civil Rights Project estimates that Black girls are among the least likely to graduate from high school. More specifically, only about half, or 56%, of freshman Black girls graduate with their class four years later. Beyond the statistics little is known about Black girls who drop out, why they leave school and what happens to them once they are gone. This study is a grounded theory analysis of the stories eight adult Black women told about dropping out of high school with a particular focus on how dropping out affected their lives as workers, mothers and returners to education. There is one conclusion about dropping out and another about Black female identity. First, the women in my study were adolescents during the 1980s, experienced life at the intersection of Blackness, womaness, and poverty and lived in the harsh conditions of a Black American hyperghetto. Using a synthesis between intersectionality and hyperghettoization I found that the women were so determined to improve their economic and personal conditions that they took on occupations that seemed to promise freedom, wealth and safety. Because they were so focused on their new lives, their school attendance suffered as a consequence. In the second conclusion I argued that Black women draw their insights about Black female identity from two competing sources. The two sources are their lived experience and popular controlling images of Black female identity.

Description
This thesis seeks to build upon the empirical use of the Copenhagen School of security studies by evaluating and investigating speech-acts in recent Guatemalan newspaper media as they relate to drug trafficking within the geopolitical borders of Guatemala, particularly induced by Los Zetas, a Mexican drug cartel. The study attempts to engage a critical theoretical framework to study securitization within the country and thereby build upon the theory by conducting real-life analysis. Using a research program that is made up of content and text analysis of national press and presidential speeches, I test several hypotheses that pertain to the processes of Guatemala's current drug trade and drug trafficking securitization. By coding securitizing speech-acts and discursive frames in the national print media, I identify the national elite, the power relations between the national elite and citizenship, and attempts to dramatize the issue of drug trade. Upon analyzing the findings of such securitization, I propose several hypotheses as to why the national elite seeks high politicization of drug trade and the implications that rest on such drastic measures. This thesis itself, then, has important implications: it uses empirical tools to help further the theoretical foundations of the Copenhagen School, it examines the process of securitization study from a real world context outside the developed world, and it presents important information on the possible consequences of securitizing drug trade.

Description
The name of Geechie Wiley has surfaced only rarely since 1931, when she recorded her second session with the Paramount Company in Grafton, WI. A few scholars including Paul Oliver and Greil Marcus unearthed and promoted her music and called for further research on this enigmatic figure. In other publications, Wiley is frequently given only passing mention in long lists of talented female blues singer-guitarists, or briefly discussed in descriptions of songsters. Her music is lauded in the liner notes of the myriad compilation albums that have re-released her recordings. However, prior to this study, Marcus's three-page profile is the longest work written about Wiley; other contributions range between one sentence and two paragraphs in length. None really answers the question: who was Geechie Wiley? This thesis begins by documenting my attempt to piece together all information presently available on Geechie Wiley. A biographical chapter, supplemented with a discussion of the blues songster, follows. I then discuss my methodology and philosophy for transcription. This is followed by a critical and comparative analysis of the recordings, using the transcriptions as supplements. Finally, my fifth chapter presents conclusions about Wiley's life, career, and disappearance. My transcriptions of Wiley's six songs are found in the first appendix. Reproductions of Paramount Records advertisements are located in the final appendix. In these ways, this thesis argues that Wiley's work traces the transformation of African-American music from the general secular music of the songsters to the iconic blues genre.

Description
This work investigates in-situ stress evolution of interfacial and bulk processes in electrochemical systems, and is divided into two projects. The first project examines the electrocapillarity of clean and CO-covered electrodes. It also investigates surface stress evolution during electro-oxidation of CO at Pt{111}, Ru/Pt{111} and Ru{0001} electrodes. The second project explores the evolution of bulk stress that occurs during intercalation (extraction) of lithium (Li) and formation of a solid electrolyte interphase during electrochemical reduction (oxidation) of Li at graphitic electrodes. Electrocapillarity measurements have shown that hydrogen and hydroxide adsorption are compressive on Pt{111}, Ru/Pt{111}, and Ru{0001}. The adsorption-induced surface stresses correlate strongly with adsorption charge. Electrocatalytic oxidation of CO on Pt{111} and Ru/Pt{111} gives a tensile surface stress. A numerical method was developed to separate both current and stress into background and active components. Applying this model to the CO oxidation signal on Ru{0001} gives a tensile surface stress and elucidates the rate limiting steps on all three electrodes. The enhanced catalysis of Ru/Pt{111} is confirmed to be bi-functional in nature: Ru provides adsorbed hydroxide to Pt allowing for rapid CO oxidation. The majority of Li-ion batteries have anodes consisting of graphite particles with polyvinylidene fluoride (PVDF) as binder. Intercalation of Li into graphite occurs in stages and produces anisotropic strains. As batteries have a fixed size and shape these strains are converted into mechanical stresses. Conventionally staging phenomena has been observed with X-ray diffraction and collaborated electrochemically with the potential. Work herein shows that staging is also clearly observed in stress. The Li staging potentials as measured by differential chronopotentiometry and stress are nearly identical. Relative peak heights of Li staging, as measured by these two techniques, are similar during reduction, but differ during oxidation due to non-linear stress relaxation phenomena. This stress relaxation appears to be due to homogenization of Li within graphite particles rather than viscous flow of the binder. The first Li reduction wave occurs simultaneously with formation of a passivating layer known as the solid electrolyte interphase (SEI). Preliminary experiments have shown the stress of SEI formation to be tensile (~+1.5 MPa).

Description
This study investigates the impact of portfolio disclosure on hedge fund performance. Using a regression discontinuity design, I investigate the effect of the disclosure requirements that take effect when an investment company's assets exceed $100 million; when that occurs, a fund is required by the SEC to submit form 13F disclosing its portfolio holdings. Consistent with the argument that portfolio disclosure reveals "trade secrets" and also raises front running costs thus harms the funds that disclose, I find that there is a drop in fund performance (about 4% annually) after a fund begins filing form 13F, as well as an increase in return correlations with other hedge funds in the same investment style. The drop in performance cannot be explained by a change in the assets under management or a mean reversion in returns. Consistent with the idea that funds with illiquid holdings tend to employ sequential trading strategies, which increase the likelihood of being taken advantage of by free riders and front runners, the drop in performance is more dramatic for funds that have more illiquid holdings. In addition, I find that the incentive fees paid to fund managers are 1% higher when portfolio disclosure is required, which supports the hypothesis that investors' monitoring of portfolio holdings disciplines adverse risk-taking by fund managers and allows for higher convexity in the optimal compensation structure. Finally, there is a drop in flows into funds that file 13F, which suggests that hedge fund investors negatively value 13F disclosure. Overall, this study suggests that the cost of portfolio disclosure is economically large. It contributes to the policy debate over what constitutes optimal disclosure.
