The purpose of this study was to examine if the implementation of a technology-based music class in public high schools in the northeastern United States had any significant impact on the overall music department enrollment and on enrollment in traditional performance ensemble courses, such as band and chorus, as they are the courses most offered in high schools in the United States. The two phases of the study included identifying eligible schools and collecting data from schools. A six-year history of music department and school enrollment data was collected from participating schools (n = 12). Individual music classes in each school were categorized as Band, Chorus, Orchestra, Technology-based, or Other Music Classes. Results found a statistically significant increase in overall Music Department enrollment and no statistically significant change in enrollment in Band or Chorus after the implementation of a technology-based music class. Reductions in enrollment did occur in Other Music classes. No significant change to the number of teachers in music departments was found. This study suggests that implementing a technology-based music classes may help increase overall music department enrollment without negatively impacting enrollment in traditional performance ensembles and may not necessitate funding for additional faculty.

Understanding how migration, genetic drift, and natural selection interact to maintain the genetic and phenotypic variation we observe in natural populations is a central goal of population genetics. Amphibians provide excellent model organisms for investigating the interplay between these evolutionary forces because amphibians are generally characterized by limited dispersal abilities, high philopatry, and are obligately associated with the areas around suitable habitats (e.g. breeding ponds). Thus, on relatively small geographic scales, the relative effects of all of these evolutionary forces can be studied together. Here, we study the interaction of migration, genetic drift, natural selection, and historical process in the ornate chorus frog (Pseudacris ornata). We report the development and characterization of 10 polymorphic microsatellite genetic markers. Number of alleles per locus ranged from 2 to 21 averaging 9.2 and expected heterozygosities ranged from 0.10 to 0.97 averaging 0.52. However, in an analysis of two populations, three locus-by-population comparisons exhibited significant heterozygote deficiencies and indicated that null alleles may be present some loci. Furthermore, we characterized genetic structure and historical biogeographic patterns in P. ornata using these microsatellite markers along with mitochondrial DNA sequence data. Our data indicate that in these frogs, migration may play a large role in determining population structure as pairwise estimates of FST were relatively small ranging from 0.04 to 0.12 (global FST = 0.083). Additionally, we observed an overall pattern of isolation-by-distance in neutral genetic markers across the species range. Moreover, our data suggest that the Apalachicola River basin does not impede gene flow in P. ornata as it does in many vertebrate taxa. Interestingly, we identified significant genetic structure between populations separated by only 6 km. However, this fine scale genetic structure was only present in the more urbanized of two widespread sampling localities. Finally, in this study, we demonstrated that there was a significant correlation between the frequency of green frogs and latitude. There was a higher frequency of green frogs in southern samples and a lower frequency of green frogs in northern samples. However, when we interpreted this phenotypic cline in light of the overall pattern of isolation-by-distance, it was apparent that the neutral evolutionary forces of genetic drift and migration could explain the cline, and the invocation of natural selection was not necessary.

This dissertation examines the dynamics of the oral communication which takes place in the Easter Vigil at St. Augustine's Anglican Church, Thaba 'Nchu. The study uses an analytical framework drawn from Orality Theory and Speech Act Theory, to analyse oral communication in the preaching and singing of the Vigil. Through an approach of Participant Observation, details were obtained of the Easter Vigils of 1994, 1995 and 1996. The historical and cultural background of this All-Night Vigil is traced in European Church History and African Traditional Religion. The roles of the Mothers' Union, the St. Agnes Guild and the Guild of Bernard Mizeki are also highlighted. / Missiology / M.Th (Missiology)

Euripides’ Phoenissae is a challenging work that is often overlooked by scholars of Greek drama. This study analyzes how the concept of autochthony occupies a central thematic concern of the play. On the one hand, autochthony unites humans to soil, political claims to myths, and present to past. On the other hand, autochthony was often invoked to exclude foreigners, women and exiles from political life at Athens. We observe a similar dichotomy in the Phoenissae. Autochthony unites the episode action–the story of the fraternal conflict—with the very different subject matter of the choral odes, which treat the founding myths of Thebes. By focalizing the lyric material through the perspective of marginalized female voices (Antigone and the chorus), Euripides is able to problematize the myths and rhetoric associated with autochthony. At the same time, Antigone’s departure with her father at the play’s close offers a transformation of autochthonous power into a positive religious entity. I suggest that a careful examination of the many facets of autochthony can inform our understanding of the Phoenissae with respect to dramatic structure, apparent Euripidean innovations, character motivation, stage direction and audience reception. / text

This dissertation examines selected literary works by Anita Rau Badami, Denise Chong, Hiromi Goto, Larissa Lai, and Kerri Sakamoto, exploring how their stories respond both to the absence of representations of Asian Canadian women in literary discourses of the early twentieth century and to homogenizing assumptions in official histories. My formulation of (re)presentation in the title recognizes the multiplicity and constructedness of these denoted identities and experiences and the self-representations of these writers as a response to this elision and misrepresentation. The term repair borrows from philosopher Hilde Lindemann Nelson’s theorizing of “narrative repair,” which involves telling counterstories, but also is used in psychological contexts as a healing mechanism. An elaboration of both models, as applied in this study, is optimally useful in diasporic contexts as resistance to the elision and/or racist and gendered discursive constructions of Asian Canadian women and as restoration of damaged identities. The texts under study—Tamarind Mem, The Concubine’s Children, Chorus of Mushrooms, When Fox Is a Thousand, and The Electrical Field—were all published in the mid-1990s, after the initial forays into the writing of novels by Asian Canadian authors such as Joy Kogawa (1981) and SKY Lee (1990). My choice of these sister narratives recognizes the family as central to identity construction and intergenerational (mis)understanding and emphasizes the importance of this period’s second-generation explosion of writings by Japanese, Chinese, and Indo Canadian women that paved the way for the current plethora of writings by authors from these cultural groups that contribute significantly to Canadian representations of diasporic identity. This study explores the nuances and pluralisms of the representations of Asian Canadian women. The texts under consideration are cultural autobiographies and matrilineal or sexually transgressive narratives that reinvent the cultural memory of Canadian women of Asian ancestry; produce cultural fusions through the transcreation of oral traditions and simulations of the oral, transcoding of ancestral tongues, and discursive strategies of silence; and address connections between self and place in examinations of Canada, the adopted country, as (un)homely territory. Presenting unhyphenated diasporic female subjects who exceed socially scripted boundaries of gender, sexuality, race, and nationality, in terms of both Canada and the writers’ and protagonists’ ancestral Asian nations, these “acts of narrative insubordination” (Nelson 8) exemplify emancipatory politics and recuperative and revisionary projects. Interrogating questions of (re)presentation and repair from positions of liminality and across gendered, racial, linguistic, and geographical divides, this research contributes to current urgent discussions of identity, transculturation, multiculturalism, and globalization in literary and cultural studies.

Acoustic communication in orthopterans and anurans provides a suitable model system for studying the evolutionary mechanisms of sexual selection mainly because males use acoustic signals to attract females over long distances for pair formation. Females use these signals not only to localize conspecific males but also to discriminate between potential mates. Investigations on the effect of sexual selection on acoustic signals requires an understanding of how female preferences for different features of the acoustic signal affect male mating success under ecological constraints in wild populations. The effect of female preferences on male mating success depends on the mate sampling strategy that females employ to search for potential mates. Despite its relevance, female mate sampling strategies based on male acoustic signals have rarely investigated in orthopterans and anurans, especially in the field. Considering the elaborate knowledge of the role of sensory physiology in female phonotaxis behaviour and characterization of the male acoustic signal, I used the field cricket species Plebeiogryllus guttiventris as a model system in this study. In this thesis, I first investigated the ecology of callers in wild populations. I then investigated female mate sampling strategies by incorporating relevant information on the ecology of signalers and the sensory physiology of receivers. Amount of calling activity is a strong determinant of male mating success in acoustically communicating species such as orthopterans and anurans. While many studies in crickets have investigated the determinants of calling effort, patterns of variability in male calling effort in natural choruses remain largely unexplored. I therefore investigated the spatio-temporal dynamics of acoustic chorusing behaviour in a wild population. I first studied the consistency of calling activity by quantifying variation in male calling effort across multiple nights of calling using repeatability analysis. Callers were inconsistent in their calling effort across nights and did not optimize nightly calling effort to increase their total number of nights spent calling. Next, I investigated calling site fidelity of males across multiple nights by quantifying movement of callers. Callers frequently changed their calling site across calling nights with substantial displacement but without any significant directionality. Finally, I investigated trade-offs between within-night calling effort and energetically expensive calling song features such as call intensity and chirp rate. Calling effort was not correlated with any of the calling song features, suggesting that energetically expensive song features do not constrain male calling effort. The two key features of signaling behaviour, calling effort and call intensity, which determine the duration and spatial coverage of the sexual signal, are uncorrelated and function independently Acoustic signal variation and female preference for different signal components constitute the prerequisite framework to study the mechanisms of sexual selection that shape acoustic communication. Despite several studies of acoustic communication in crickets, information on both male calling song variation in the field and female preference in the same system is lacking for most species. First, I quantified variation in the spectral, temporal and amplitudinal characteristics of the male calling song in a wild population, at two temporal scales, within and across nights, using repeatability analysis. Carrier frequency (CF) was the most repeatable call trait across nights, whereas chirp period (CP) had low repeatability. I further investigated female preferences based on song features with high and low repeatability (CF and CP respectively). Females showed no consistent preferences for CF but were more attracted towards calls with higher rates (shorter CP). I also examined the effect of signal intensity, which is known to play a critical role in female phonotaxis behaviour, on female preferences for faster calls. Females preferred louder calls over faster ones, implying a dominant role for signal intensity in female evaluation of potential mates based on acoustic signals. Call intensity was also the only signal feature that was positively correlated with male size. In the final chapter, I investigated female mate sampling strategies based on acoustic signals using both theoretical and empirical approaches. Analytical models of mate sampling have demonstrated significant differences in individual fitness returns for different sampling strategies. However these models have rarely incorporated relevant information on the ecology of signalers and the sensory physiology of receivers. I used simulation models to compare the costs and benefits of different mate sampling strategies by incorporating information on relative spacing of callers in natural choruses and the effect of signal intensity on female phonotaxis behaviour. The strategy of mating with males that were louder at the female position emerged as the optimal sampling rule in the simulations. When tested empirically in the field using callers in natural choruses, females seemed to follow the optimal strategy of mating with males that were perceived as louder at their position.
