Frederick Douglass and Ireland, 1845: The "Vertiginous Twist[s]" of an Irish Encounter

Frederick Douglas was a reader of and writer on the nineteenth-century political and social texts and contexts of oppression, which he experienced at home and witnesed while in Ireland and Britain, 1845-47. This thesis is unique in its identification of several surprising lacunae in the research and critical evaluation of Frederick Douglass’ activities of reading and writing and the texts and contexts that supported these activities. This thesis takes Douglass’ relationship with Ireland and the Irish as its starting point, and offers several moments in the transnational space engendered by Douglass’ readerly and writerly experience of the transatlantic axes of Ireland, Britain and America. This thesis draws upon archival research to recover information regarding Douglass’ trip and subjects his reading and writing on Ireland and the Irish to the critical rigours of narratolgical, cultural and discourse analysis. One lacuna is Douglass’ favourite and neglected school primer, the Columbian Orator, which Douglass signified upon across his autobiographical project. The speech by the Irish patriot and exile, Arthur O’Connor, included in the Orator, is crucial to Douglass’ understanding and expression of justice and equality. Genette’s narratological analysis gives theoretical traction to the ways in which, in his autobiographical representations of his British trip, Douglass recalibrates his autobiographies to reflect his changing perspectives on his life and work. Contrary to popular assumptions, Douglass did, in two letters to Garrison address and comment on Irish poverty. This thesis interrogates the strategic anglophilia of these letters. While the World’s Temperance Convention (WTC) refused to discuss African- American slavery, analysis of Douglass’ speech in Covent Garden and of the paratextual apparatus of the published proceedings of the WTC demonstrates the impossibility of separating these closely interrelated reform causes. When a newly discovered poem from Waterford that admonished the city for its disregard for Douglass’ message is juxtaposed with an uncomfortable moment in Cork, we understand that Douglass became a pawn to bolster sectarian rivalries between nationalist and establishment factions. Though Douglass believed imperial politics was the best vehicle for modernity, he recognised that it had failed Ireland: consequently, in Thoughts and Recollections of a Trip to Ireland (1886), he advocates for Home Rule for Ireland.

Elicitation techniques for the evaluation of speech under stress: Towards a framework for use in a controlled environment

Existing work in Computer Science and Electronic Engineering demonstrates that Digital Signal Processing techniques can effectively identify the presence of stress in the speech signal. These techniques use datasets containing real or actual stress samples i.e. real-life stress such as 911 calls and so on. Studies that use simulated or laboratory-induced stress have been less successful and inconsistent. Pervasive, ubiquitous computing is increasingly moving towards voice-activated and voice-controlled systems and devices. Speech recognition and speaker identification algorithms will have to improve and take emotional speech into account. Modelling the influence of stress on speech and voice is of interest to researchers from many different disciplines including security, telecommunications, psychology, speech science, forensics and Human Computer Interaction (HCI). The aim of this work is to assess the impact of moderate stress on the speech signal. In order to do this, a dataset of laboratory-induced stress is required. While attempting to build this dataset it became apparent that reliably inducing measurable stress in a controlled environment, when speech is a requirement, is a challenging task. This work focuses on the use of a variety of stressors to elicit a stress response during tasks that involve speech content. Biosignal analysis (commercial Brain Computer Interfaces, eye tracking and skin resistance) is used to verify and quantify the stress response, if any. This thesis explains the basis of the author’s hypotheses on the elicitation of affectively-toned speech and presents the results of several studies carried out throughout the PhD research period. These results show that the elicitation of stress, particularly the induction of affectively-toned speech, is not a simple matter and that many modulating factors influence the stress response process. A model is proposed to reflect the author’s hypothesis on the emotional response pathways relating to the elicitation of stress with a required speech content. Finally the author provides guidelines and recommendations for future research on speech under stress. Further research paths are identified and a roadmap for future research in this area is defined.
