Holding Space for Each Other’s Stories: A Phenomenological Study of an Adolescent Story Slam

abstract: This research features a phenomenological investigation of the interactions between adolescent storytellers and audience members during a live storytelling event. The researcher partnered with an English teacher in an urban Southwest high school and a spoken word poet from a youth nonprofit to produce a storytelling workshop and corresponding story slam event for high school students. Fourteen participants, including seven student storytellers and seven student audience members, participated in extensive follow-up interviews where they described the experience of their respective roles during the event. Utilizing a phenomenological design (Moustakas, 1994; Vagle, 2014) and drawing from reception theory (Bennett, 1997; Hall, 1980) as a framework, the researcher used participant descriptions to compose a textural-structural synthesis collectively describing the phenomenon of interaction, connection, and transaction between storytellers and audience members during the live event. The textural-structural synthesis of participants’ descriptions comprises four major essences of the transactional phenomenon. These include 1) the relational symbiosis of storytellers and audience members, 2) the nature of the story slam as a planned and produced event, 3) the storytellers’ inclusions of specific, personal details which resonated with specific, personal details in audience members’ lives, and 4) the storytellers’ intentional style and content choices which corresponded with reactions from audience members. These findings provide a platform for fostering conditions for interaction, connection, and transaction in curricular and extra-curricular secondary contexts. For a classroom teacher, they may be helpful in creating principles for optimizing interactions between teachers and students in instruction and between students in collaboration. In extra-curricular contexts, these findings provide a platform for consideration of how to hold space for creative performance once spaces for creative expression have been made for youth.Dissertation/ThesisDoctoral Dissertation English 201

The Year in C-SPAN Archives Research: Volume 4

C-SPAN is the network of record for US political affairs, broadcasting live gavel-to-gavel proceedings of the House of Representatives and the Senate, and to other forums where public policy is discussed, debated, and decided––without editing, commentary, or analysis and with a balanced presentation of points of view. The C-SPAN Archives, located adjacent to Purdue University, is the home of the online C-SPAN Video Library. The Archives has copied all of C-SPAN\u27s television content since 1987. Extensive indexing, captioning, and other enhanced online features provide researchers, policy analysts, students, teachers, and public officials with an unparalleled chronological and internally cross-referenced record for deeper study. The Year in C-SPAN Archives Research presents the finest interdisciplinary research utilizing tools of the C-SPAN Video Library. Each volume highlights recent scholarship and comprises leading experts and emerging voices in political science, journalism, psychology, computer science, communication, and a variety of other disciplines. Each section within each volume includes responses from expert discussants. Developed in partnership with the Brian Lamb School of Communication and with support from the C-SPAN Education Foundation, C-SPAN Insights is guided by the ideal that all experimental outcomes, including those from our American experiment, can be best improved by directed study driving richer engagement and better understanding. The Year in C-SPAN Archives Research—Volume 4, edited by Robert X. Browning, advances our understanding of the framing of mental health, HIV/AIDS, policing, and public health, and explores subjects such as audience reactions in C-SPAN covered debates, the Twitter presidency of Donald Trump, and collaborative learning using the C-SPAN Video Library

Real-time generation and adaptation of social companion robot behaviors

Social robots will be part of our future homes. They will assist us in everyday tasks, entertain us, and provide helpful advice. However, the technology still faces challenges that must be overcome to equip the machine with social competencies and make it a socially intelligent and accepted housemate. An essential skill of every social robot is verbal and non-verbal communication. In contrast to voice assistants, smartphones, and smart home technology, which are already part of many people's lives today, social robots have an embodiment that raises expectations towards the machine. Their anthropomorphic or zoomorphic appearance suggests they can communicate naturally with speech, gestures, or facial expressions and understand corresponding human behaviors. In addition, robots also need to consider individual users' preferences: everybody is shaped by their culture, social norms, and life experiences, resulting in different expectations towards communication with a robot. However, robots do not have human intuition - they must be equipped with the corresponding algorithmic solutions to these problems. This thesis investigates the use of reinforcement learning to adapt the robot's verbal and non-verbal communication to the user's needs and preferences. Such non-functional adaptation of the robot's behaviors primarily aims to improve the user experience and the robot's perceived social intelligence. The literature has not yet provided a holistic view of the overall challenge: real-time adaptation requires control over the robot's multimodal behavior generation, an understanding of human feedback, and an algorithmic basis for machine learning. Thus, this thesis develops a conceptual framework for designing real-time non-functional social robot behavior adaptation with reinforcement learning. It provides a higher-level view from the system designer's perspective and guidance from the start to the end. It illustrates the process of modeling, simulating, and evaluating such adaptation processes. Specifically, it guides the integration of human feedback and social signals to equip the machine with social awareness. The conceptual framework is put into practice for several use cases, resulting in technical proofs of concept and research prototypes. They are evaluated in the lab and in in-situ studies. These approaches address typical activities in domestic environments, focussing on the robot's expression of personality, persona, politeness, and humor. Within this scope, the robot adapts its spoken utterances, prosody, and animations based on human explicit or implicit feedback.Soziale Roboter werden Teil unseres zukünftigen Zuhauses sein. Sie werden uns bei alltäglichen Aufgaben unterstützen, uns unterhalten und uns mit hilfreichen Ratschlägen versorgen. Noch gibt es allerdings technische Herausforderungen, die zunächst überwunden werden müssen, um die Maschine mit sozialen Kompetenzen auszustatten und zu einem sozial intelligenten und akzeptierten Mitbewohner zu machen. Eine wesentliche Fähigkeit eines jeden sozialen Roboters ist die verbale und nonverbale Kommunikation. Im Gegensatz zu Sprachassistenten, Smartphones und Smart-Home-Technologien, die bereits heute Teil des Lebens vieler Menschen sind, haben soziale Roboter eine Verkörperung, die Erwartungen an die Maschine weckt. Ihr anthropomorphes oder zoomorphes Aussehen legt nahe, dass sie in der Lage sind, auf natürliche Weise mit Sprache, Gestik oder Mimik zu kommunizieren, aber auch entsprechende menschliche Kommunikation zu verstehen. Darüber hinaus müssen Roboter auch die individuellen Vorlieben der Benutzer berücksichtigen. So ist jeder Mensch von seiner Kultur, sozialen Normen und eigenen Lebenserfahrungen geprägt, was zu unterschiedlichen Erwartungen an die Kommunikation mit einem Roboter führt. Roboter haben jedoch keine menschliche Intuition - sie müssen mit entsprechenden Algorithmen für diese Probleme ausgestattet werden. In dieser Arbeit wird der Einsatz von bestärkendem Lernen untersucht, um die verbale und nonverbale Kommunikation des Roboters an die Bedürfnisse und Vorlieben des Benutzers anzupassen. Eine solche nicht-funktionale Anpassung des Roboterverhaltens zielt in erster Linie darauf ab, das Benutzererlebnis und die wahrgenommene soziale Intelligenz des Roboters zu verbessern. Die Literatur bietet bisher keine ganzheitliche Sicht auf diese Herausforderung: Echtzeitanpassung erfordert die Kontrolle über die multimodale Verhaltenserzeugung des Roboters, ein Verständnis des menschlichen Feedbacks und eine algorithmische Basis für maschinelles Lernen. Daher wird in dieser Arbeit ein konzeptioneller Rahmen für die Gestaltung von nicht-funktionaler Anpassung der Kommunikation sozialer Roboter mit bestärkendem Lernen entwickelt. Er bietet eine übergeordnete Sichtweise aus der Perspektive des Systemdesigners und eine Anleitung vom Anfang bis zum Ende. Er veranschaulicht den Prozess der Modellierung, Simulation und Evaluierung solcher Anpassungsprozesse. Insbesondere wird auf die Integration von menschlichem Feedback und sozialen Signalen eingegangen, um die Maschine mit sozialem Bewusstsein auszustatten. Der konzeptionelle Rahmen wird für mehrere Anwendungsfälle in die Praxis umgesetzt, was zu technischen Konzeptnachweisen und Forschungsprototypen führt, die in Labor- und In-situ-Studien evaluiert werden. Diese Ansätze befassen sich mit typischen Aktivitäten in häuslichen Umgebungen, wobei der Schwerpunkt auf dem Ausdruck der Persönlichkeit, dem Persona, der Höflichkeit und dem Humor des Roboters liegt. In diesem Rahmen passt der Roboter seine Sprache, Prosodie, und Animationen auf Basis expliziten oder impliziten menschlichen Feedbacks an

A multimodal approach to persuasion in oral presentations : the case of conference presentations, research dissemination talks and product pitches

Esta tesis presenta un estudio multimodal y etnográfico del uso de estrategias persuasivas en tres géneros orales: presentaciones en conferencias, charlas de divulgación científica, y presentaciones de productos. Estos géneros comparten un importante componente persuasivo: los tres se dirigen a una audiencia tratando de convencerles del valor de un producto, servicio, o investigación. Sin embargo, se usan en dos contextos profesionales diferentes: el académico y el económico, por lo que cabe esperar que consigan su propósito comunicativo de forma diferente. Por otra parte, recientes estudios muestran como distintos discursos, tienden a adoptar cada vez más rasgos promocionales (promocionalización del discurso). En vista de ello, es factible establecer como hipótesis que los tres géneros están relacionados interdiscursivamente, y un estudio multimodal y etnográfico del uso de la persuasión en dichos géneros puede ayudar a clarificar las relaciones existentes entre ellos, así como sus diferencias.This thesis is a multimodal and ethnographic study of the use of persuasive strategies in three oral genres conference presentations, research dissemination talks and product pitches. These presentations share a strong persuasive component in their communicative purpose: the three of them address an audience to convince them of the value of a product, a service or a piece of research. However, they are used in business and academia by different discourse communities in different contexts, and therefore they can be expected to achieve their communicative goals in different ways. In addition, research suggests that there is a trend towards promotionalization of different discourses, among which academic discourse is included. In view of this, I hypothesize that these three genres are intertextually and interdiscursively related, and that a multimodal and ethnographic study of the use of persuasion in them can help to shed some light on these relationships and differences

Exposing the hidden vocal channel: Analysis of vocal expression

This dissertation explored perception and modeling of human vocal expression, and began by asking what people heard in expressive speech. To address this fundamental question, clips from Shakespearian soliloquy and from the Library of Congress Veterans Oral History Collection were presented to Mechanical Turk workers (10 per clip); and the workers were asked to provide 1-3 keywords describing the vocal expression in the voice. The resulting keywords described prosody, voice quality, nonverbal quality, and emotion in the voice, along with the conversational style, and personal qualities attributed to the speaker. More than half of the keywords described emotion, and were wide-ranging and nuanced. In contrast, keywords describing prosody and voice quality reduced to a short list of frequently-repeating vocal elements. Given this description of perceived vocal expression, a 3-step process was used to model vocal qualities which listeners most frequently perceived. This process included 1) an interactive analysis across each condition to discover its distinguishing characteristics, 2) feature selection and evaluation via unequal variance sensitivity measurements and examination of means and 2-sigma variances across conditions, and 3) iterative, incremental classifier training and validation. The resulting models performed at 2-3.5 times chance. More importantly, the analysis revealed a continuum relationship across whispering, breathiness, modal speech, and resonance, and revealed multiple spectral sub-types of breathiness, modal speech, resonance, and creaky voice. Finally, latent semantic analysis (LSA) applied to the crowdsourced keyword descriptors enabled organic discovery of expressive dimensions present in each corpus, and revealed relationships among perceived voice qualities and emotions within each dimension and across the corpora. The resulting dimensional classifiers performed at up to 3 times chance, and a second study presented a dimensional analysis of laughter. This research produced a new way of exploring emotion in the voice, and of examining relationships among emotion, prosody, voice quality, conversation quality, personal quality, and other expressive vocal elements. For future work, this perception-grounded fusion of crowdsourcing and LSA technique can be applied to anything humans can describe, in any research domain
