Abstract Any type of discourse consists of spans of utterances (segments) displaying a coherent relationship. Narratives are thought to be composed of clearly recognizable semantically independent segments (or sections). There exist several approaches attempting to describe this underlying grammar (or mode0 of narrative. However, no empirical evidence of such a grammar, using spontaneous, non-elicited data has been presented so far. The present study examines the role prosody plays in the assigning of boundaries in narrative discourse. It also investigates the recurrence of specific prosodic features in semantically individualized narrative sections. if prosody is found to reveal the segmentation of narrative and to characterize narrative sections by means of a recurrent pattern, this constitutes evidence that (oral) narrative presents a well-defined structure. The data consist of 17 spontaneous / non-elicited narrative texts, told in the course of conversations between the researcher and 8 subjects, under appropriate laboratory condition. lnspired by the literature, the following prosodic variables were selected for analysis: pause, speech rate, pitch range, pitch Eset and boundary tones. It was found that the boundaries occuning between narrative sections (narrative bounduies) are prosodically different from those tbat occur exclusively between clauses (clause boundaries). This was verified in temof (i) pause occurrence and duration (pauses occur more frequently and are generaiiy longer at narrative boundaries), (ii) pitch reset values (the difference in pitch range values between two adjacent clauses is higher at narrative boundaries) and (iii) boundary tones (low boundary tones usually occur at narrative boundaries). Further, it was observed that narrative sections are regularly characterized by the recurrence of specifk prosodic patterns. such as (i) variation in speech rate (slower speech rates characterize sections considered highly relevant, faster rates characterize sections of low relevance), and (ii) variation in pitch range (higher pitch ranges characterize sections considered highly relevant, lower pitch ranges characterize sections of low relevance). These findings lead to the conclusion that spontaneously produced narratives are frarned by an underlying stnicture, and that storytellers appear to be awace of such a structure. This awareness is evidenced through the systematic employment of prosodic devices. This thesis was only possible because of the help and support of a number of people. 1would tike to thank everybody who directiy or indirectly contributed to it. Some people deserve speciai mention.

  • A History of Morgan County, Utah Centennial County History Series
    610 square miles, more than 90 percent of which is privately owned. Situated within the Wasatch Mountains, its boundaries defined by mountain ridges, Morgan Countyhas been celebrated for its alpine setting. Weber Can- yon and the Weber River traverse the fertile Morgan Valley; and it was the lush vegetation of the pristine valley that prompted the first white settlers in 1855 to carve a road to it through Devils Gate in lower Weber Canyon. Morgan has a rich historical legacy. It has served as a corridor in the West, used by both Native Americans and early trappers. Indian tribes often camped in the valley, even long after it was settled by Mormon pioneers. The southern part of the county was part of the famed Hastings Cutoff, made notorious by the Donner party but also used by Mormon pioneers, Johnston's Army, California gold seekers, and other early travelers. Morgan is still part of main routes of traffic, including the railroad and utility lines that provide service throughout the West. Long known as an agricultural county, the area now also serves residents who commute to employment in Wasatch Front cities.

  • Toward a Poetics of Animality: Hofmannsthal, Rilke, Pirandello, Kafka
    Toward a Poetics of Animality: Hofmannsthal, Rilke, Pirandello, Kafka Kári Driscoll Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 © 2014 Kári Driscoll All rights reserved Abstract Toward a Poetics of Animality: Hofmannsthal, Rilke, Pirandello, Kafka Kári Driscoll Toward a Poetics of Animality is a study of the place and function of animals in the works of four major modernist authors: Hugo von Hofmannsthal, Rainer Maria Ril- ke, Luigi Pirandello, and Franz Kafka. Through a series of close readings of canonical as well as lesser-known texts, I show how the so-called “Sprachkrise”—the crisis of language and representation that dominated European literature around 1900—was inextricably bound up with an attendant crisis of anthropocentrism and of man’s rela- tionship to the animal. Since antiquity, man has been defined as the animal that has language; hence a crisis of language necessarily called into question the assumption of human superiority and the strict division between humans and animals on the ba- sis of language. Furthermore, in response to author and critic John Berger’s provoca- tive suggestion that “the first metaphor was animal,” I explore the essential and constantly reaffirmed link between animals and metaphorical language. The implica- tion is that the poetic imagination and the problem of representation have always on some level been bound up with the figure of the animal. Thus, the ‘poetics of animal- ity’ I identify in the authors under examination gestures toward the origin of poetry and figurative language as such.

Walsh November, 2018 ABSTRACT This is a collection of four stories, two of which are short and two of which (so far) fall into the nebulous category of the long short story. All are works in progress. The stories focus much on moments of small, fraught drama between characters who have strong, if ill-defined, feelings about each other. The protagonists are confused, obsessive types who attempt, with very limited success, to understand their own feelings and motivations—to distinguish between delusion and truthful perception. Prominent themes include romantic longing, jealousy, loneliness, self-awareness, egotism, and responsibility for others. On the sociopolitical level, the stories are concerned with issues of economics, social class, gender identity, and racism, as filtered through the perceptions, feelings, and thoughts of white, primarily heterosexual, working-class Americans.

  • Unconventional Wisdom
    UNCONVENTIONAL WISDOM University of Montevallo TRIO McNair Scholars Program 2014 Research Journal Welcome I am delighted to provide the welcome for the second issue of Unconventional Wisdom: University of Montevallo McNair Scholars Program Research Journal. The McNair Scholars Program combines two of my higher education passions: access for those who are underrepresented in U.S. higher education and undergraduate research. As this is a research journal it is only appropriate I cite research about the benefits of undergraduate research. The American Association of Colleges and Universities (AAC&U) identifies 10 high-impact practices, which benefit undergraduate students (Kuh, 2008). One of these is undergraduate research. Research by Dr. George Kuh (2008) suggests that while most students benefit from high-impact practices, these practices may be more beneficial for traditionally underrepresented students. This “compensatory effect” results in a larger accrual of benefits to those who are less prepared when they enter college (Finley & McNair, 2013). Undergraduate research can narrow the gap. It has been a true joy to see the McNair Scholars as they progress through the program. From their research proposals presented to the University of Montevallo community in the spring, through the workshops and working with faculty mentors in May and June, to the presentations of their results in June, to the publication of this journal, I have seen such growth in the McNair Scholars as students, researchers, and human beings. One of the greatest pleasures is to see them accepted into graduate programs as a result of their dedication and hard work and the support of the program director, Dr.
