1. López de Victoria Rodríguez, Patria Celeste. NARRATIVES OF SELF IN OLDER BILINGUAL ADULTS DIAGNOSED WITH ALZHEIMER'S DISEASE.

Degree: PhD, Applied Linguistics, 2016, Penn State University

As the boom in the older adult population continues to grow, so too grows the number of persons suffering from cognitive diseases, such as dementia of the Alzheimer’s type (DAT). Older Latinos diagnosed with the disease make up 4 percent (200,000) of the current population; however, little research on bilinguals with DAT has been carried out (Gollan, et al. 2010, 2011; Bialystok, 2007), and even less on the presentation of self as mediated through narrative production. Current literature in the area has found that even though there is an internal (neuropathological and neuropsychological) decline that affects those diagnosed with DAT, individuals with DAT continue to display an external or social self. That is, individuals with DAT demonstrate a sense of personhood, or the “standing or status that is bestowed upon one human being by others, in the context of relationship and social being” (Kitwood, 1997, p. 7). As my work is situated in the discursive perspective of selfhood, the current study sought to answer questions regarding the presentation of self as mediated through narrative production in three cognitively healthy and three cognitively impaired older bilingual Latinos. While using a tri-partite framework from which to analyze bilingual data in studies of linguistic nature—including repeated tellings, reported speech, and speaker roles—I analyzed in both of the speakers’ languages (1) the content of the participants’ twice-told narratives, (2) the enactment of self and others, and (3) the shifts in speaker roles. The findings demonstrated that participants with DAT continued to display their sense of self in first and second tellings, making a variety of lexical choices to index the self and their subjectivity. Retellings, however, were more favorable for the participants with DAT as twice-told stories seemed to enhance these speakers’ overall access to memory, language, and narrative ability. The findings present evidence that the notion of the sense of self is grounded in discursive and interactional contexts, can be publicly manifested via narratives of personal experience, and is enhanced through the act of narrative retellings.

2. Sapru, Ashtosh. Automatic social role recognition and its application in structuring multiparty interactions.

Degree: 2015, EPFL

Automatic processing of multiparty interactions is a research domain with important applications in content browsing, summarization and information retrieval. In recent years, several works have been devoted to find regular patterns which speakers exhibit in a multiparty interaction also known as social roles. Most of the research in literature has generally focused on recognition of scenario specific formal roles. More recently, role coding schemes based on informal social roles have been proposed in literature, defining roles based on the behavior speakers have in the functioning of a small group interaction. Informal social roles represent a flexible classification scheme that can generalize across different scenarios of multiparty interaction. In this thesis, we focus on automatic recognition of informal social roles and exploit the influence of informal social roles on speaker behavior for structuring multiparty interactions. To model speaker behavior, we systematically explore various verbal and non verbal cues extracted from turn taking patterns, vocal expression and linguistic style. The influence of social roles on the behavior cues exhibited by a speaker is modeled using a discriminative approach based on conditional random fields. Experiments performed on several hours of meeting data reveal that classification using conditional random fields improves the role recognition performance. We demonstrate the effectiveness of our approach by evaluating it on previously unseen scenarios of multiparty interaction. Furthermore, we also consider whether formal roles and informal roles can be automatically predicted by the same verbal and nonverbal features. We exploit the influence of social roles on turn taking patterns to improve speaker diarization under distant microphone condition. Our work extends the Hidden Markov model (HMM)- Gaussian mixture model (GMM) speaker diarization system, and is based on jointly estimating both the speaker segmentation and social roles in an audio recording. We modify the minimum duration constraint in HMM-GMM diarization system by using role information to model the expected duration of speaker's turn. We also use social role n-grams as prior information to model speaker interaction patterns. Finally, we demonstrate the application of social roles for the problem of topic segmentation in meetings. We exploit our findings that social roles can dynamically change in conversations and use this information to predict topic changes in meetings. We also present an unsupervised method for topic segmentation which combines social roles and lexical cohesion. Experimental results show that social roles improve performance of both speaker diarization and topic segmentation. Advisors/Committee Members: Bourlard, Hervé.

3. Grafinger, Stephanie Helena. An analysis of radio phone-ins.

Degree: 2010, University of Vienna

Diese Arbeit beschäftigt sich mit der Analyse von Phone-In Sendungen am Beispiel der „FM4 Morning Show“. Als Grundlage dieser Arbeit dient ein Korpus von 11 Gesprächen, zwischen Stuart Freeman (SF), dem Moderator der „FM4 Morning Show“ und dem jeweiligen Kandidaten. Diese Interaktionen, welche täglich live ausgestrahlt werden, wurden sorgfältig transkribiert und anschließend analysiert. Es wird besonders auf die Verlaufsform sowie die strukturelle Organisation des Gesprächs eingegangen und typische Phasen des Gesprächs werden analysiert. Dabei wird ein Augenmerk auf die Gesprächseröffnung und –beendigung gelegt. Aus den Rahmenbedingungen und der Struktur der Phone-in Sendung ergibt sich ein spezifisches Machtverhältnis zwischen den Sprechern, welches die Rollenverteilung im Gespräch beeinflusst. Daher werden in dieser Arbeit verschiedene Typen von Sprechern und Hörern unterschieden und ihre Aufgaben und Aktivitäten, wie zum Beispiel die Übernahme und Aufrechterhaltung des Gesprächs, untersucht. Als letzter Punkt wird wegen dem mehrsprachigen Format des Senders auf spezielle Aspekte der „native - non-native communication“ (NS-NNS) eingegangen.

The present paper seeks to contribute to the linguistic description of mediated native-non-native conversation. This study examines talk on an Austrian multilingual radio station and explores radio talk as a form of institutional or rather semi-institutional discourse. The sequential organization of phone-ins is explored using the methodology of Conversation Analysis. Furthermore the management of participation in calls to a FM4 radio phone-in program is analyzed and participatory roles of the host, the audience and the caller are examined. In this context the role of the speaker and the listener as well as a variety of activities which are performed by them, such as turn taking, backchanneling or politeness phenomena are outlined. The paper concludes with a chapter in which aspects about the multilingual setting in which the phone-ins are conducted are discussed. It includes the use of more than one linguistic variety within the same conversation, miscommunication and strategies to overcome potential problems.
