Concept-based Interactive Query Expansion Support Tool (CIQUEST)

This report describes a three-year project (2000-03) undertaken in the Information Studies Department at The University of Sheffield and funded by Resource, The Council for Museums, Archives and Libraries. The overall aim of the research was to provide user support for query formulation and reformulation in searching large-scale textual resources including those of the World Wide Web. More specifically the objectives were: to investigate and evaluate methods for the automatic generation and organisation of concepts derived from retrieved document sets, based on statistical methods for term weighting; and to conduct user-based evaluations on the understanding, presentation and retrieval effectiveness of concept structures in selecting candidate terms for interactive query expansion. The TREC test collection formed the basis for the seven evaluative experiments conducted in the course of the project. These formed four distinct phases in the project plan. In the first phase, a series of experiments was conducted to investigate further techniques for concept derivation and hierarchical organisation and structure. The second phase was concerned with user-based validation of the concept structures. Results of phases 1 and 2 informed on the design of the test system and the user interface was developed in phase 3. The final phase entailed a user-based summative evaluation of the CiQuest system. The main findings demonstrate that concept hierarchies can effectively be generated from sets of retrieved documents and displayed to searchers in a meaningful way. The approach provides the searcher with an overview of the contents of the retrieved documents, which in turn facilitates the viewing of documents and selection of the most relevant ones. Concept hierarchies are a good source of terms for query expansion and can improve precision. The extraction of descriptive phrases as an alternative source of terms was also effective. With respect to presentation, cascading menus were easy to browse for selecting terms and for viewing documents. In conclusion the project dissemination programme and future work are outlined

The REVERE project:Experiments with the application of probabilistic NLP to systems engineering

Despite natural language’s well-documented shortcomings as a medium for precise technical description, its use in software-intensive systems engineering remains inescapable. This poses many problems for engineers who must derive problem understanding and synthesise precise solution descriptions from free text. This is true both for the largely unstructured textual descriptions from which system requirements are derived, and for more formal documents, such as standards, which impose requirements on system development processes. This paper describes experiments that we have carried out in the REVERE1 project to investigate the use of probabilistic natural language processing techniques to provide systems engineering support

Adapting the Ward Method for Use in the Private Voice Studio

The Ward Method is a progressive approach to vocal music education designed for elementary and intermediate students in Catholic Schools. However, due to the solid foundation of vocal pedagogy inherent to the Method, as well as its philosophies of educational psychology that govern its structure and approach, the Ward Method has implications that go far beyond elementary parochial music education. The concepts of vocal and educational pedagogy that distinguish the Ward Method are presented and compared to historical and current sources. An description of the component elements of the method and how they are used in the context of a lesson is also included. Three case studies examine how the Method may be adapted for use outside of the classroom setting to address a broad spectrum of vocal applications, including: correcting non-amusic “tone-deafness” in an adult male; addressing specific deficiencies of musical and vocal understanding in an adolescent female; and preparing difficult literature with a chorus of amateur singers. In each case, lesson plans are included with notes explaining what modifications were made and, more importantly, which elements of the Method were followed

Doctor of Philosophy

dissertationThe purpose of this constructivist grounded theory study was to identify and examine challenges and strategies used by people with parkinsonism to maintain identity. These concerns were explored within the context of daily life, vital relationships, and familiar roles. The setting was three Midwestern states during historic winter weather conditions (2013-2014). Illness descriptions were obtained through medication logs and two scales: Hoehn and Yahr staging and activities of daily living. Qualitative data consisted of 62 in-depth interviews, photos, videos, fieldnotes, and memos. Twenty-five volunteers (10 female/15 male; ages 40-95) with self-reported Parkinson disease participated. Range of disease duration was 3 months to 30 years. Disease staging: I (n = 0), II (n = 0), III (n = 14), IV (n = 8), and V (n = 3). Stage III participants completed daily living activities at an independence level of 60 to 80%, while stage V participants ranged from 20 to 30%. Twenty-one participants used carbidopa-levodopa. Analytic coding procedures generated the theory of Preserving self. This clinically logical 5-staged theory represents social and psychological processes for maintaining identity while living with a life-limiting illness. The stages and transitions are: (1) Making sense of symptoms describes noticing and taking action prediagnosis. Transition: Finding out the diagnosis was shocking, but time-limited. (2) Turning points confronted abilities with demanding tasks and strong emotions. Transition: Unsettling reminders of losses were perpetual. (3) Dilemmas of identity are the difficulties relinquishing comfortable self-attributes. Transition: Sifting and sorting is a time of grieving, letting go, and considering new self-identities. (4) Reconnecting the self synthesizes former and current identities. Transition: Balancing risks and rewards compares a lost past with possible futures. (5) Envisioning a future demonstrates planning pragmatically with tunnel vision. iv Creative methods were developed for maintaining independence; abilities were frequently overestimated. An interesting finding was the use of self-adjusted carbidopa-levodopa beginning during Sifting and sorting continuing through Reconnecting the self. Medication was used as a social prosthesis to function normally, maintain valued relationships, and roles. People with parkinsonisim desperately seek normalcy. Recommendations include medication instruction to bridge wearing-off effects and sensory integrative activities as a self-reconnecting technique

Teaching Google search techniques in an L2 academic writing context

This mixed-method study examines the effectiveness of teaching Google search techniques (GSTs) to Korean EFL college students in an intermediate-level academic English writing course. 18 students participated in a 4-day GST workshop consisting of an overview session of the web as corpus and Google as a concordancer, and three training sessions targeting the use of quotation marks (“”) and a wildcard (*). Each session contained a pre-test, a 30-minute training, and a post-test, and each training session focused on one of the three key writing points: articles, collocations, and paraphrasing. Two questionnaires for demographic information and GST learning experiences were conducted. The results showed a statistically significant effect for the overall gain score. In particular, participants’ use of articles greatly improved after the training—in contrast to their use of collocations and paraphrasing. Lack of grammar and vocabulary knowledge seemed to hinder their data-driven learning, especially for collocation use and paraphrasing. The questionnaire data showed that all students found the GSTs beneficial, mostly because they were easy to use for confirmation and correction. Overall, both quantitative and qualitative data suggest that teachers’ meticulous guidance and vigilant individualized feedback are necessary to facilitate L2 self-directed Google-informed writing

Can Big Whales Inspire Big Behaviors? A Study of Environmental Communication, and Nature Immersion

Direct contact with wild nature is becoming harder for people to access in present times, yet research suggests that experiencing nature is important to the formation of environmental values, which may lead to conservation behaviors. My thesis experiment theorizes that direct contact with nature has the ability to impact people\u27s behavioral beliefs and intentions toward the environment, applying Icek Ajzen\u27s Theory of Planned Behavior (TPB) and the New Ecological Paradigm Scale as measures. A questionnaire was administered post-whale watching trips in Juneau, Alaska to determine whether whales, direct experience with charismatic megafauna, could stimulate positive attitudes and behaviors toward recycling. The proposed study fills in gaps of previous research by adding a communication variable, in addition to the whales experienced, and measuring its effect with the questionnaire. This communication message expressed the link between people\u27s recycling behaviors and whales well-being. The study utilized participants\u27 intensity of experience with a whale as a second independent variable, and this whale acts as a proposed symbol for the environment at large. Recycling was chosen as the targeted behavior for this study, but the behavior is meant to represent positive behaviors toward the environment on a grander scale. This thesis research is intended to be a case study of whether nature, and human-mediated communication about it, can stimulate positive behaviors toward the environment. The study\u27s results affirmed positive TPB correlations, providing further support for the TPB model when applied to environmentally friendly behavioral intentions. Overall participants reported high ecological values, but questionnaire responses indicated that level of intensity of nature experience, and a human- mediated communication message, had little to no significant effect on reported behavioral intentions toward recycling, negating what had been hypothesized. More research is needed to further comprehend the interactions between experience in nature, human-mediated communication, and TPB

Quiet Supersonic Flights 2018 (QSF18) Test: Galveston, Texas Risk Reduction for Future Community Testing with a Low-Boom Flight Demonstration Vehicle

The Quiet Supersonic Flights 2018 (QSF18) Program was designed to develop tools and methods for demonstration of overland supersonic flight with an acceptable sonic boom, and collect a large dataset of responses from a representative sample of the population. Phase 1 provided the basis for a low amplitude sonic boom testing in six different climate regions that will enable international regulatory agencies to draft a noise-based standard for certifying civilian supersonic overland flight. Phase 2 successfully executed a large scale test in Galveston, Texas, developed well documented data sets, calculated dose response relationships, yielded lessons, and identified future risk reduction activities
