Using a mobile application to reduce anxiety levels, stress levels, and panic severity in a sample of the general population
No full textDuring the COVID-19 pandemic, people are feeling more anxious and stressed than ever. As such, mobile solutions that minimize face-to-face contact and can reduce anxiety and stress in the public are needed. The mobile application “Rootd” could be one such solution and we sought to investigate this mobile health application further. In the present work, we recruited 41 participants from the community and had them use the Rootd app on a regular basis. To assess whether Rootd decreased anxiety levels, stress levels, and panic incidence and severity, we had participants complete assessments before using the application (the pre-application period) and after four to six weeks of using the application (the post-application period). All participants were collected during the COVID-19 pandemic. We found that the use of the application led to a decrease in both anxiety and stress levels on two well-validated questionnaires and per the participants’ self-report. As well, we found that Rootd did not decrease panic attack incidence but did decrease panic attack severity. These findings build upon previous investigations that have adopted mobile-health approaches and mindfulness to help treat anxiety, stress, and panic. Moreover, given our generalized sample and the short intervention timeframe, these findings provide evidence that mobile health solutions are invaluable to help people manage anxiety, stress, and panic, during times when face-to-face interaction is reduced – such as during the COVID-19 pandemic
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
