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
Sharing is caring: an analysis of #FOAMed Twitter posts during the COVID-19 pandemic
No full textPurpose: Free Open Access Medical Education (FOAMed) is a worldwide social media movement designed to accelerate and democratise the sharing of medical knowledge. This study sought to investigate the content shared through FOAMed during the emerging COVID-19 pandemic.Study design: tweets containing the #FOAMed hashtag posted during a 24-hour period in April 2020 were studied. Included tweets were analysed using the Wiig knowledge management cycle framework (building knowledge, holding knowledge, pooling knowledge and using knowledge).Results: 1379 tweets contained the #FOAMed hashtag, of which 265 met the inclusion criteria and were included in the analysis. Included tweets were posted from 208 distinct users, originated from each world continent and were in five different languages. Three overarching themes were identified: (1) signposting and appraising evidence and guidelines; (2) sharing specialist and technical advice; and (3) personal and social engagement. Among 12 subthemes within these groupings, 11 aligned to one of the four dimensions of the Wiig knowledge management cycle framework, and the other focused on building and managing social networks. Almost 40% of tweets related directly to COVID-19.Conclusion: #FOAMed tweets during the COVID-19 pandemic included a broad range of resources, advice and support. Despite the geographical, language and disciplinary variation of contributing users and the lack of organisational structure uniting them, this social media medical community has been able to construct, share and use emerging technical knowledge through a time of extraordinary challenge and uncertainty for the global medical community.</p
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
The self-presentation of Facebook users in Hong Kong
No full textM.Phil.Hong Kong’s social media penetration rate is one of the highest in Asia. Online social activities have taken up a large part of people’s lives (Census and Statistics Department 2018). However, efforts to study the social implications of the increasing popularity of these platforms are lacking in Hong Kong. Research done on social media in Hong Kong is usually conducted by new media scholars. Anthropological perspectives on the subject matter are almost non-existent in Hong Kong. By contributing to our understanding of social media, this research investigates specifically the self-presentation of young Facebook users in Hong Kong.This thesis draws upon Erving Goffman’s dramaturgical theory (1956). Goffman suggests that individuals are constantly working to build and maintain an appropriate impression on the audience. But appropriateness depends on the definition of the target audience. In order for this to succeed, individuals need to segregate the audience so that different impressions tailored to different audiences and situations can be maintained. Grounded in the dramaturgical theory, I examine in this research how Facebook users make sense of their self-presentation by exploring different contexts of posting despite the convergence of different groups of friends on Facebook.香港的社交媒体渗透率为亚洲地区中最高之一。网上社交成为大多数人日常生活不可或缺的一部分（政府统计处 2018）。然而，社会缺乏针对社交媒体对香港社交影响的研究。现存有关社交媒体在香港的情况主要是新媒体学者探讨社交媒体对香港政治的影响，人类学在香港社交媒体的研究寥寥可数。通过描述受访者对社交媒体的理解，本论文旨在研究香港青年人在脸书上的自我呈现。欧文·戈夫曼（Erving Goffman） 提出的戏剧理论（theory of dramaturgy），认为个体为了迎合不同的观众，需要不断的判断观众的喜好，并因其各自喜好建立并保持不同的形象。这个过程中，为了在观众前保持一致和妥当的形象，至为重要是把不同需要或喜好的观众分隔开。本论文借鉴戈夫曼的戏剧理论，研究在不同“观众”同时存在在脸书平台的背景下，香港脸书使用者在不同情况下的脸书发表中如何理解当下的自我呈现。Au, Wing Lam Vivian."December 2019."Thesis M.Phil.
