The role of dissolved organic matter in structuring microbial community composition:
No full textDissolved organic matter (DOM) is an important source of nutrients in aquatic systems contributing to the growth of phytoplankton and bacteria. The overall response appears to be driven by the phytoplankton and bacteria species present as well as the composition of DOM provided. This dissertation explores the bioavailability of allochthonous and autochthonous DOM sources to, and its affect on, the growth of marine phytoplankton and bacterial community abundance and composition.
This research utilizes advanced chemical (electrospray ionization mass spectrometry (ESI-MS)) and molecular (terminal restriction fragment length polymorphism (TRFLP)) techniques to characterize the DOM and microbial community. To investigate the role of allochthonous DOM in phytoplankton growth, DOM from two different riverine sources from watersheds with different land use practices, was supplied to a natural cyanobacteria population. The bioavailability of autochthonous DOM was investigated by supplying DOM produced by a single culture of cyanobacteria to a natural dinoflagellate bloom community. The potential negative effect of an individual autochthonous DOM compound was investigated through the addition of marine toxin, brevetoxin, to three different natural bacterial communities.
This dissertation resulted in the first ESI-MS characterization spectra of the DOM associated with three different natural phytoplankton blooms, a culture of cyanobacteria, and two different South Florida rivers. It was also the first study to identify previously uncharacterized allochthonous and autochthonous DOM masses bioavailable to natural marine phytoplankton communities. Bulk level analyses within these experiments quantified lower limits for the bioavailability of allochthonous and autochthonous DOM sources and the relative community response to each of these sources. This dissertation also represents the first molecular evaluation of the bacteria associated with a bloom and the first investigation of the allelopathic properties of brevetoxin. It has discussed and applied the use of ESI-MS to investigate the bioavailability of complex DOM, identified and quantified potential nutrient sources and linked marine toxin production to changes in bacterial community composition.Ph.D.Includes bibliographical referencesby Rachel Elizabeth Siple
Versed in war: the preservation and publication of Second World War poetry by the Salamander Oasis Trust
No full textThis dissertation describes the collection of poetry by men and women in the British and Commonwealth armed forces written during the Second World War. The project which ultimately became the Salamander Oasis Trust Archive began in Cairo, Egypt in 1942, when three low-ranking servicemen decided to gather poetry for an anthology Oasis: The Middle East Anthology of Poetry from the Forces. Following the war, the editors and contributors gathered to re-form their group, republish the anthology and, over the next twenty years, produce four more. Despite the efforts of the Trust and the vast store of poetry and letters amassed in its archive at the Imperial War Museum, Duxford, the Salamander Oasis poems are relatively unknown in literary scholarship. "Versed in War" explores the literary scene in Cairo, the importance of reading and writing among servicemen and women, the writing practices of novice poets as well as the reasons for the unfortunate obscurity of the SOTA poems, including publishing conditions in wartime London, competing beliefs about the place of culture in war, and fixed ideas about poetry which devalue novices' verse.
Drawing upon archival materials, published anthologies and contemporary journals and reviews, this dissertation is intended not only to broaden awareness of the collection and its value to scholars and readers of poetry, but also to frame the poems in ways which suggest their potential as historical and cultural artifacts for enriching our understanding of what poetry means to those who choose it as their mode of expression in the most desperate circumstances of their lives, and to develop as set of questions which make these poems meaningful and relevant to post-war generations of readers.Ph.D.Includes bibliographical references (p. 235-241

Gender Matters: Amante's Gender Construction in Elizabeth Gaskell's "The Grey Woman"
No full textElizabeth Gaskell’s reputation as an author and position within the canon has long been contested and debated forming a narrative of an almost “anti-feminist” or “minor” author in Victorian Literature. Shifting perceptions of her work have recently argued for a more progressive reading and understanding of her work, reimagining particularly her novels in a feminist framework. I propose that Elizabeth Gaskell’s works also deserve some consideration in the realm of queer theory, particularly her Gothic short story, The Grey Woman. Through an analysis of the gender construction and evolution of the cross-dressing, and arguably cross-gendering, character Amante, I argue the text not only presents Amante as a potentially male-identifying character but also validates her gender construction through the use of plot devices and narrative framework. I place Amante’s situation in conversation with another of Gaskell’s cross-dressing characters, Peter Jenkyns from Cranford, to show how the layout and plot elements of a story can play a large, if subtle, part in both validating and constructing a character’s gender identity

Change, loss, and grief in organizations
No full textThis symposium, titled “Change, Loss, and Grief in Organizations,” explores the multifaceted impact of change, loss, and grief on employees and organizations. Change, loss, and grief—whether personal or professional—are universal experiences that shape the work-life interface. However, organizational scholarship has only begun to unpack the complex ways these experiences influence individuals and workplaces. This symposium advances understanding by examining the varied and nuanced ways individuals process both personal and professional change, loss, and grief, including how these processes affect communication, sense-making, and recovery; and strategies organizations, leaders, and colleagues can adopt to effectively support those navigating these experiences and emotions. Bringing together diverse methodological approaches—mixed methods, qualitative, and quantitative—this symposium highlights innovative perspectives on how employees experience, cope with, and adapt to change, loss, and grief in the workplace. Research-based insights from these papers aim to inform organizational policies and practices that foster resilience, compassion, and well-being. The symposium seeks to engage scholars interested in change, loss, and grief, while offering actionable recommendations for future research and practice.

In Search of an Author: From Participatory Culture to Participatory Authorship
No full textThe question of fidelity, which has long been at the center of adaptation studies, pertains to the problem of authorship. Who can be an author and adapt a text and who cannot? In order to understand the problem of fidelity, this thesis asks larger questions about the problems of authorship, examining how authorship is changing in new media. Audiences are taking an ever-increasing role in the creation and interpretation of the texts they receive: a phenomenon this thesis refers to as participatory authorship, or the active participation of audience members in the creation, expansion, and adaptation of another\u27s creative work. In order to understand how audiences are creating texts, first the place of the player within video games is addressed. Due to the nature of the medium, players must become active co-creators of a video game. Drawing a parallel between video game players and performance, it is argued that players must simultaneously perform and author a text, illustrating the complex and multilayered nature of authorship in video games. In the second chapter the role of the fan is examined within the context of the My Little Pony fandom, Bronies. Like players, fans take an active role in the creation of the text and destabilize the traditional notion of authorship by partially controlling of a text from the original author. By examining the place of the player and the fan the traditional notion of authorship is destabilized, and the more open and collaborative model of participatory authorship is proposed
High-throughput screening for ADP-ribosyl hydrolase 3 inhibitors
No full textPoly(ADP-ribose) (PAR) signaling is an important component of DNA damage repair, DNA replication, and initiation of parthanatos, a method of controlled cell death. While PAR has been well studied for decades, much is still unknown about PAR’s initiation of parthanatos and the importance of mono(ADP-ribose) (MAR) in cellular regulation. The lack of knowledge in this field can be attributed in part to the lack of a cell-permeable tool compound to study the activity of ARH3, a key degrader of PAR and MAR. Toward filling this need, a high-throughput screen was conducted using a fluorogenic substrate to discover an inhibitor of ARH3. A total of 496 primary hits have been identified and will be further studied to validate their ability to inhibit ARH3.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-12-01The student, Rachel Farmer, accepted the attached license on 2020-12-07 at 16:50.The student, Rachel Farmer, submitted this Thesis for approval on 2020-12-07 at 16:50.This Thesis was approved for publication on 2020-12-08 at 11:23.DSpace SAF Submission Ingestion Package generated from Vireo submission #16085 on 2021-03-04 at 16:33:51Made available in DSpace on 2021-03-05T21:47:34Z (GMT).

Music and elite identity in the English country house, c.1790-1840
No full textIn this thesis I investigate two untapped music book collections that belonged to two women. Elizabeth Sykes Egerton (1777-1853) and Lydia Hoare Acland (1786-1856) lived at Tatton Park, Cheshire, and Killerton House, Devon, respectively. Upon their marriage in the early nineteenth century, they brought with them the music books they had compiled so far to their new homes, and they continued to collect and play music after marriage. I examine the vocal music in Elizabeth’s and Lydia’s collections, and I aim to show how selected vocal music repertoires contributed toward the construction of landed elite identity in these women and their husbands, concentrating on gender, class, national identity and religion.In chapter one, I concentrate on songs that depict destitute and suffering individuals to move both listeners and performers to compassion. The songs are topical and provide insights into contemporary understandings of sympathy and landed elite responsibility for the distressed. In chapter two, I focus on the ingoing and outgoing movements of music in the country house, and the consumption of foreign music in the home. I divide the chapter into two sections, first examining Elizabeth’s Italian vocal music that she collected during her girlhood years in London and York in the 1790s. The Italian music that Elizabeth brought to Tatton complemented other Italian objects and items in the home. Italian culture appealed to the Egerton family both before and after Elizabeth and Wilbraham married. In the second section, I investigate Lydia and her family’s journey to Vienna for the Congress in 1814-1815. Lydia took away with her a book of vocal music to remind her of home in a foreign environment. While away in Vienna, the Aclands attended concerts and music salons, and they purchased music books to bring back home to add to their collection. In the final chapter, I concentrate on the man of the house at music and I consider the social expectations, duties and responsibilities that had befallen our landed elite men, Thomas Dyke Acland and Wilbraham Egerton. I discuss Thomas’s and Wilbraham’s musical engagements and occasions for performing music, and how men’s music-making contributed to a masculine identity.By placing the vocal music in broader social and cultural contexts, reading personal correspondence, newspaper articles, account books and diaries, we can begin to understand what our families thought about music, and how they used and experienced music in and around their homes, forming an important part of their lifestyle
Open destinies : modern American women and the short story cycle
No full textThis thesis examines the juncture between the short story cycle form and gender politics. It explores how twentieth-century women from the United States have been using the form to represent and question gender identity. The introduction outlines commentaries on the story cycle and considers definitions of the form. It includes case studies of earlier twentieth-century cycles by American women: cycles such as Mary McCarthy's The Company She Keeps that have been passed over by critics of the form.
Chapter One presents Eudora Welty's The Golden Apples as a cycle paradigm, examining conventions such as the form's metafictional dimension and its preoccupation with communal identity. Chapter Two argues that Grace Paley's scattered Faith narratives set a standard for more dispersed versions of the form. Chapter Three considers how Joyce Carol Oates uses the sequential cycle to represent gender identity as a social construct. Chapters Four and Five examine the macrocosmic cycles of Gloria Naylor and Louise Erdrich and consider changes in their form and gender politics. The final 'composite' chapters explore postmodern versions of the form such as Susan Minot's Monkeys. The prose works of Sandra Cisneros stretch across the story cycle continuum, whilst Toni Morrison's Paradise is universally regarded as a novel. Readings of contemporary cycles by Melissa Bank, Elissa Schappell and Emily Carter demonstrate that American women are re-invigorating the form to facilitate the plural identity of the postmodern heroine
