Investigating the Trustworthiness of Research Evidence Used to Inform Public Health Policy: A Descriptive and Qualitative Study on the Use of Predatory Journal Citations in Public Health Policy Documents
No full textBackground: The evidence-based approach to policymaking has greatly facilitated policymakers' capacity to make scientifically informed policy decisions, especially in the medical and public health contexts. However, this approach is most beneficial for policy development when trustworthy research is used. Predatory journals and publishers pose a potential threat to evidence-based policy making, since they are more likely than traditional academic journals to publish unreliable evidence.
Research Objectives: The purpose of this thesis is to advance knowledge on what factors contribute to the citation of predatory journal articles in policy documents by answering the following research questions: 1) How do people preparing public health documents consider the trustworthiness of research evidence? 2) How do they source and evaluate the research evidence they cite?
Methods: I identified a cross-sectional sample of public health policy documents from Overton - the world's largest policy document database - that cited articles published by the OMICS group. OMICS is a well-established predatory publisher. I extracted meta-data (e.g., document source) and document characteristics such as whether they described their method of selection or quality assessment for cited sources. Authors of these documents with contact information listed, as well as a convenience sample of people who have prepared public health documents, were invited for a semi-structured interview. I thematically analyzed these interviews by organizing the codes (both deductive and inductive) into key overarching themes.
Results: Two hundred forty-two public health policy documents were included. The World Health Organization was the most common source accounting for 45 documents (19%). A total of 283 articles were cited from 126 OMICS journals. Only 54 (22%) of the policy documents described their source-selection methodology, and 22 (9%) assessed the quality of cited sources. Five key overarching themes were generated from the thematic analysis of the interview data, highlighting that information cited in policy documents is sourced and evaluated in several ways, many of which are related to a series of factors which could be contributing to the predatory journal citations.
Conclusion: Public health policy documents are prepared using a variety of methods for information selection and evaluation, but the exact approach for doing so is rarely reported within the document itself. This may contribute to the reliance on untrustworthy research to inform policy; and thus, may help amplify misinformation entering policy globally. Certain steps can be taken to help minimize any potential negative impact of relying on such sources, but a better understanding of policymakers' perspectives may be required to ensure successful implementation
Reactions to Governmental Public Health Organizations Post-COVID-19: A Social Media Analysis
No full textThe purpose of this thesis was to examine the reactions to Canadian public health organizations' messaging through a social media analysis by answering the following two research questions: 1) How did different levels of government use social media communication to inform the public of COVID-19 information during the reopening phase? 2) What was the public response to the lifting of COVID-19 measures? COVID-19-related Tweets posted by Ottawa Public Health (OPH), Public Health Ontario (PHO), and Health Canada and the Public Health Agency of Canada (HC & PHAC) and their replies were collected using the Twitter API through Python. Sentiment analysis of the data was conducted using the VADER tool. This was followed by a thematic analysis of Twitter threads to identify patterns in the Tweets posted by each organization and their respective replies. Results of the VADER sentiment analysis indicate OPH Tweets were mostly positive, whereas HC & PHAC Tweets were slightly more positive than neutral. PHO Tweets were mostly neutral. Public social media replies to the selected public health organizations were also measured; replies to both OPH and HC & PHAC were more negative than positive, although replies to OPH were slightly more positive compared to replies to HC & PHAC. Thematic analysis revealed five themes regarding public health organizations' use of social media communications and eight themes relating to the public response to information posted by the selected public health organizations. The results from both sentiment and thematic analysis can help inform recommendations to enhance communication by Canadian governmental organizations, especially in public health systems, and offer recommendations for public health social media communication to inform future disaster response policies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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 linkWe 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
