There and Back Again: From Conducting User Survey Research to Creating and Evaluating a Platform for Creating Data-Driven Surveys
No full textHumanity's scientific and technological progress is marked by leaps in advancement, especially in the field of computing. The advent of the Internet enabled an unprecedented acceleration in technological progress. It has led to increased digitization of peoples' lives. Quantified selfers (Q-selfers) are people who try to digitize their lives as much as possible [ 338 ]. They were the first group to adopt wearable activity trackers (WATs) that are devices worn on the body to collect physiological, environmental, and/or contextual information. Since then, WATs have become increasingly popular. WATs offer a variety of benefits to end-users, however, they also come with downsides, such as privacy and security risks. Hence, studying them is important to better understand users' perceptions of WATs. One of the most common ways of studying WATs is using online surveys (henceforth, surveys) that are questionnaires administered via online web forms. The last major technological leap with surveys was when online surveys started to become popular, as online surveys offer many advantages over their predecessor paper- and phone-based counterparts [358].
This thesis is a composition of several articles that are adapted into chapters. This thesis makes the following contributions: First, we present the utility-related sections from a systematic literature review on the utility, privacy, and security aspects of WATs; the author of this thesis was a coauthor of the systematic literature review. This bridges a research gap of there being no systematic literature reviews that cover those three aspects of WAT literature. Second, we conduct a mixed-methods study to investigate WATs users' perceptions of utility and privacy, understanding of WATs and the WAT ecosystem, and potential Privacy Enhancing Technologies (PETs). From this work, we conclude that WAT users tend to not understand how their WAT data is processed and stored. We suggest ways to address this, such as improving privacy education and improvements to WAT companion app user interfaces (UIs). We identify opportunities for PETs, such as storing data only on WAT users' smartphones. During the course of this study, we noticed that having access to participants' WAT data could benefit surveys. Third, we investigate improving surveys by integrating participants' online account data to create data-driven surveys. We conduct a systematic literature review to identify opportunities for integrating participants' online account data to improve the survey and/or data collection. Based on our findings, we envision three features for a platform that can enable creating data-driven surveys, by using data collected from online accounts to: create templated questions and answers, customize survey flow and display/skip logic, and enabling the creation of “custom variables” based on rules determined by researchers. To evaluate the interest in, and utility of, our envisioned features, we conduct a survey with researchers from various fields that use surveys in their research. We found that researchers were generally interested and found our proposed features useful. Hence, we designed and implemented an open-source data-driven survey system called Data-Driven Surveys (DDS). DDS integrates with the Qualtrics and SurveyMonkey survey platforms (SPs), and with Fitbit, GitHub, and Google Contacts as data providers (DPs) that are platforms from which participants' online account data can be integrated in surveys. Fourth, we investigate the potential of using data-driven surveys in fitness tracking. We conduct a data-driven survey with three participant groups, two of which were required to grant us access to their Fitbit data, to evaluate participants' perceptions of privacy and utility of data-driven surveys, the discrepancies that exist between self-reported data and their online account data, and the value of additional monetary compensation that could encourage participation in data-driven surveys. To gain more accurate estimates of the additional monetary compensation, we conduct an additional experiment where participants are given a choice between granting access to their data (in exchange for varying amounts of extra monetary compensation) or completing a survey manually. We find that while participants generally found data-driven surveys useful, many of them had privacy concerns regarding granting us access to their Fitbit data. There are notable discrepancies between participants' self-reported answers and their Fitbit data. Finally, an extra monetary incentive of USD 1 was sufficient to maximize the proportion of participants (16-18%) that have Fitbit data in their Fitbit account, granting us access to their Fitbit data. We discuss the reasons reported by participants for the choices that they made. Using our findings, we offer suggestions to researchers conducting surveys and data-driven surveys.
Finally, this thesis discusses the ethical implications of paying participants to share data in data-driven surveys, provides an overall discussion of the findings and contributions, and proposes avenues for future work to explore. Then, this thesis concludes with a summary of its contributions
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
