Advancing automation and robotics technology for the Space Station and for the US economy, volume 2

In response to Public Law 98-371, dated July 18, 1984, the NASA Advanced Technology Advisory Committee has studied automation and robotics for use in the Space Station. The Technical Report, Volume 2, provides background information on automation and robotics technologies and their potential and documents: the relevant aspects of Space Station design; representative examples of automation and robotics; applications; the state of the technology and advances needed; and considerations for technology transfer to U.S. industry and for space commercialization

Spoken conversational search: audio-only interactive information retrieval

Speech-based web search where no keyboard or screens are available to present search engine results is becoming ubiquitous, mainly through the use of mobile devices and intelligent assistants such as Apple's HomePod, Google Home, or Amazon Alexa. Currently, these intelligent assistants do not maintain a lengthy information exchange. They do not track context or present information suitable for an audio-only channel, and do not interact with the user in a multi-turn conversation. Understanding how users would interact with such an audio-only interaction system in multi-turn information seeking dialogues, and what users expect from these new systems, are unexplored in search settings. In particular, the knowledge on how to present search results over an audio-only channel and which interactions take place in this new search paradigm is crucial to incorporate while producing usable systems. Thus, constructing insight into the conversational structure of information seeking processes provides researchers and developers opportunities to build better systems while creating a research agenda and directions for future advancements in Spoken Conversational Search (SCS). Such insight has been identified as crucial in the growing SCS area. At the moment, limited understanding has been acquired for SCS, for example how the components interact, how information should be presented, or how task complexity impacts the interactivity or discourse behaviours. We aim to address these knowledge gaps. This thesis outlines the breadth of SCS and forms a manifesto advancing this highly interactive search paradigm with new research directions including prescriptive notions for implementing identified challenges. We investigate SCS through quantitative and qualitative designs: (i) log and crowdsourcing experiments investigating different interaction and results presentation styles, and (ii) the creation and analysis of the first SCS dataset and annotation schema through designing and conducting an observational study of information seeking dialogues. We propose new research directions and design recommendations based on the triangulation of three different datasets and methods: the log analysis to identify practical challenges and limitations of existing systems while informing our future observational study; the crowdsourcing experiment to validate a new experimental setup for future search engine results presentation investigations; and the observational study to establish the SCS dataset (SCSdata), form the first Spoken Conversational Search Annotation Schema (SCoSAS), and study interaction behaviours for different task complexities. Our principle contributions are based on our observational study for which we developed a novel methodology utilising a qualitative design. We show that existing information seeking models may be insufficient for the new SCS search paradigm because they inadequately capture meta-discourse functions and the system's role as an active agent. Thus, the results indicate that SCS systems have to support the user through discourse functions and be actively involved in the users' search process. This suggests that interactivity between the user and system is necessary to overcome the increased complexity which has been imposed upon the user and system by the constraints of the audio-only communication channel. We then present the first schematic model for SCS which is derived from the SCoSAS through the qualitative analysis of the SCSdata. In addition, we demonstrate the applicability of our dataset by investigating the effect of task complexity on interaction and discourse behaviour. Lastly, we present SCS design recommendations and outline new research directions for SCS. The implications of our work are practical, conceptual, and methodological. The practical implications include the development of the SCSdata, the SCoSAS, and SCS design recommendations. The conceptual implications include the development of a schematic SCS model which identifies the need for increased interactivity and pro-activity to overcome the audio-imposed complexity in SCS. The methodological implications include the development of the crowdsourcing framework, and techniques for developing and analysing SCS datasets. In summary, we believe that our findings can guide researchers and developers to help improve existing interactive systems which are less constrained, such as mobile search, as well as more constrained systems such as SCS systems

Hybrid discourse modeling and summarization for a speech-to-speech translation system

The thesis discusses two parts of the speech-to-speech translation system VerbMobil: the dialogue model and one of its applications, multilingual summary generation. In connection with the dialogue model, two topics are of special interest: (a) the use of a default unification operation called overlay as the fundamental operation for dialogue management; and (b) an intentional model that is able to describe intentions in dialogue on five levels in a language-independent way. Besides the actual generation algorithm developed, we present a comprehensive evaluation of the summarization functionality. In addition to precision and recall, a new characterization - confabulation - is defined that provides a more precise understanding of the performance of complex natural language processing systems.Die vorliegende Arbeit behandelt hauptsächlich zwei Themen, die für das VerbMobil-System, ein Übersetzungssystem gesprochener Spontansprache, entwickelt wurden: das Dialogmodell und als Applikation die multilinguale Generierung von Ergebnissprotokollen. Für die Dialogmodellierung sind zwei Themen von besonderem Interesse. Das erste behandelt eine in der vorliegenden Arbeit formalisierte Default-Unifikations-Operation namens Overlay, die als fundamentale Operation für Diskursverarbeitung dient. Das zweite besteht aus einem intentionalen Modell, das Intentionen eines Dialogs auf fünf Ebenen in einer sprachunabhängigen Repräsentation darstellt. Neben dem für die Protokollgenerierung entwickelten Generierungsalgorithmus wird eine umfassende Evaluation zur Protokollgenerierungsfunktionalität vorgestellt. Zusätzlich zu "precision" und "recall" wird ein neues Maß - Konfabulation (Engl.: "confabulation") - vorgestellt, das eine präzisere Charakterisierung der Qualität eines komplexen Sprachverarbeitungssystems ermöglicht

Conceptions of effective information use and learning in a tele-health organization: a phenomenographic study of information literacy and knowledge management at work.

This research study investigates the concept of workplace information literacy (IL) theoretically and empirically, focusing on the connections between information literacy and knowledge management (KM). This dissertation examines the relevance and applicability of current IL frameworks in a workplace environment by means of a review of the literature, a review of NHS Scotland documentation on its KM initiatives, and a phenomenographic study undertaken with frontline staff at NHS24, a nurse-led, 24/7 service of NHS Scotland that provides over-the-phone consultation and health information. For that study, a working definition of IL as effective information use was employed. The concept of information literacy has been developed mainly within librarianship, researched mainly within educational contexts and focused on individual competence in information use. While its application to workplace environments has been assumed, comparatively little research has been done into workplace situations. On the other hand, the concept of knowledge management is directed at a wider organizational level. However, while there is a clear focus in the KM literature on the value of information and its importance for organizations, little attention has been paid to the theoretical and empirical developments of Library and Information Science (LIS) relative to information behaviour and effective information use. The findings of this research identified limitations in the current IL frameworks, notably the lack of consideration for peoples exchanges of knowledge and information and of the social sense making that influences information interpretation and application. The findings endorse views of learning and information use grounded in socio-constructive perspectives and a consideration of context as situated practice. The conclusions suggest the need for more collaboration between studies of IL and information behaviour, and for LIS research to focus more on workplace studies and knowledge management

Lived Experience of Military Mental Health Clinicians: Provided Care to OIF and OEF Active Duty Service Members Experiencing War Stress Injury

Military mental health clinicians (MMHCs) have been essential to Operations Enduring Freedom and Iraqi Freedom. They served in extreme stress conditions, including on the front lines. As co-combatant/clinician, the MMHC bridged unique perspectives on the effects of war stress experienced by Active-Duty Service Members (ADSMs). To date, no study has focuses uniquely on MMHCs narratives as they provided care from this multiple perspective. This investigation was carried out from a phenomenological perspective. A single, open-ended question was asked of seven MMHCs about lived experiences while serving, resulting in in-depth interviews. These were textually coded. Though clinician positive and negative experiences were consistent with previous research, significant differences bear discussion. Following data analysis, participants identified duty as the superordinate theme that led to the question, Duty to military mission or service member? This dilemma could not be reconciled that resulted in unrealized fulfillment of duty. MMHCs responses to unrealized duty defined an overarching polarity of Integrity-Corruption A hermeneutic approach was used to identify the author\u27s relevant understandings before, during, and after the interview process. In reconstructing and contextualizing interview material, one finding was that MMHCs were required to operate in a place of turbulence between contradictory military and psychological traditions. Another finding concerned a growing divisive fissure between military and the public at-large, impacting reintegration efforts for those who serve. Public and governmental silence about traumas of ADSMs and MMHCs suggests a parallel, cultural dissociation occurring about war trauma. A question is posed if diagnosing trauma as pathology is a further way that external, contextual forces are consistently kept unformulated, distanced or denied. Rather than locating the etiology and treatment entirely within the individual - resulting in blaming and isolating of those who serve - the suggestion is made for widespread discussion of socioeconomic and political factors that are behind psychological war injury.
