    Thesis (Ph.D.)--University of Washington, 2019Surgery patients engage in health information-seeking activities to better understand their health conditions. An example of this activity is patients collecting data outside of the hospital to track their surgery recovery. Patients can also seek health information from resources such as clinicians, patient education materials, multimedia, friends or family members, and websites to answer their questions. However, surgery patients could encounter barriers when trying to make sense of their collected data or engaging in health information-seeking. For example, clinicians have limited availability to help make sense of the collected data or answer patient questions. Additionally, surgery patients may have low health literacy levels or have difficulties recalling their discharge teaching. In this dissertation, I will first describe how patients collecting data outside of the hospital has an impact on patient-clinician relationships and patient efforts to make sense of the data through information-seeking. Second, I will detail an innovative approach to aid inguinal hernia surgery patient information-seeking activities - a prototype health dialog system, called “Hernia Coach,” built as a Google Assistant “Action.” To develop Hernia Coach, I investigated the information needs of inguinal hernia surgery patients by engaging patients and clinicians in participatory design sessions. Then I designed and developed Hernia Coach. Finally, I evaluated Hernia Coach to identify the system's ability to aid patient health information-seeking by recruiting design experts to perform a heuristic evaluation, engaging patients in user testing sessions, and evaluating the Hernia Coach’s ability to provide relevant health information to participant queries. This research contributes to an improved understanding of how patients collecting data to address health concerns affect patient-clinician relationships, expands on inguinal hernia surgery patient informational needs research, and demonstrates how health dialog systems can act as a tool to aid patients with their health information-seeking activities. My work also has implications beyond inguinal hernia surgery. When patients engage in health information-seeking online, the onus is on them to identify material relevant to their health condition that also contains accurate information. Health dialog systems have the potential to act as patient-centered health information repositories and allow patients to easily ask questions and quickly receive reliable answers from a reputable resource. Additionally, my work provides design recommendations for researchers creating these systems and identifies opportunities to improve the evaluation of patient-centered health dialog systems

    While chronic diseases remain a global problem, visualizations of data and information are a potential solution to assist patients with chronic disease in communication, self-management, and decision making. The purpose of this systematic review is to synthesize evidence regarding data and information visualizations integrated into consumer health informatics solutions for chronic disease management in the community. A search was conducted in CINAHL, EMBASE, Engineering Village, PsycINFO, PubMed, and Web of Science between January 1, 2007, and May 1, 2019. Studies were evaluated using the Mixed Methods Appraisal Tool. Of the 2549 published studies, six studies met inclusion criteria. Of these six studies, two used information visualizations, two used data visualizations, and two used both information and data visualizations. Graphs were the main type of visualization used. Visualizations were mainly delivered in mobile applications and were interactive. The goals of the visualizations varied across studies including to (1) improve understanding of health data, (2) improve patient-provider communication, (3) monitor chronic disease, and/or (4) improve chronic disease management. Five studies reported subjective outcomes of the visualizations (eg, perceived usability, acceptability). One study reported both subjective and objective outcomes (eg, recall) of the visualizations. Findings highlight the need for more research on data and information visualizations integrated into consumer health technologies that support chronic disease management in daily life

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
