Older Adults' Experiences with Misinformation on Social Media
Get PDFOlder adults habitually encounter misinformation on social media, but there
is little knowledge about their experiences with it. In this study, we combined
a qualitative survey (n=119) with in-depth interviews (n=21) to investigate how
older adults in America conceptualize, discern, and contextualize social media
misinformation. As misinformation on social media in the past was driven
towards influencing voting outcomes, we were particularly interested to
approach our study from a voting intention perspective. We found that 62% of
the participants intending to vote Democrat saw a manipulative political
purpose behind the spread of misinformation while only 5% of those intending to
vote Republican believed misinformation has a political dissent purpose.
Regardless of the voting intentions, most participants relied on source
heuristics combined with fact-checking to discern truth from misinformation on
social media. The biggest concern about the misinformation, among all the
participants, was that it increasingly leads to biased reasoning influenced by
personal values and feelings instead of reasoning based on objective evidence.
The participants intending to vote Democrat were in 74% of the cases concerned
that misinformation will cause escalation of extremism in the future, while
those intending to vote Republican, were undecided, or planned to abstain were
concerned that misinformation will further erode the trust in democratic
institutions, specifically in the context of public health and free and fair
elections. During our interviews, we found that 63% of the participants who
intended to vote Republican, were fully aware and acknowledged that Republican
or conservative voices often time speak misinformation, even though they are
closely aligned to their political ideology
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
Children, Parents, and Misinformation on Social Media
Get PDFChildren encounter misinformation on social media in a similar capacity as
their parents. Unlike their parents, children are an exceptionally vulnerable
population because their cognitive abilities and emotional regulation are still
maturing, rendering them more susceptible to misinformation and falsehoods
online. Yet, little is known about children's experience with misinformation as
well as what their parents think of the misinformation's effect on child
development. To answer these questions, we combined a qualitative survey of
parents (n=87) with semi-structured interviews of both parents and children
(n=12). We found that children usually encounter deep fakes, memes with
political context, or celebrity/influencer rumors on social media. Children
revealed they "ask Siri" whether a social media video or post is true or not
before they search on Google or ask their parents about it. Parents expressed
discontent that their children are impressionable to misinformation, stating
that the burden falls on them to help their children develop critical thinking
skills for navigating falsehoods on social media. Here, the majority of parents
felt that schools should also teach these skills as well as media literacy to
their children. Misinformation, according to both parents and children affects
the family relationships especially with grandparents with different political
views than theirs
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
