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

No full textTouch-ups, Rejuvenation, Re-dos and Revisions: Remote Communication and Cosmetic Surgery on the Rise
No full textThe way in which communication takes place has undergone significant change over the last year leading to alterations regarding the way we perceive our own personal image. Indeed, the increase in remote video interaction seems to have led to an increase in the number of requests for teleconsultations with plastic surgeons in private practice (70% in the UK and 64% in the USA), the so-called Zoom Boom. The reasons connected to this increase are still under investigation, but it is likely that patients’ greater exposure to seeing their own image in online video communication for prolonged periods has highlighted what patients perceive as flaws and/or their self-image does not correspond to the same image that they see in the mirror. However, the motivations for seeking cosmetic surgery cannot be solely attributed to seeing ourselves online more frequently; the psychological impact of the pandemic (lower moods, isolation and greater concerns) may also be to blame. Therefore, the reasons patients hope to touch-up, rejuvenate, re-do or revise their “lockdown faces” need careful attention with a view to understand the extent of which the online distortion of one’s own body image may be the underlying cause.

The Psychological Impact of Remote Communication on Body-Image Perception: Cosmetic Surgery on the Rise.
Full text linkIn recent times the number of requests for teleconsultations with plastic surgeons in private practice (70% in the UK and 64% in the USA) has increased. The correlation between this increase and the concept of "Zoom Boom" changing how we perceive our image is under speculation. However, this could also be linked to the psychological impact of the pandemic on patients' moods. This study investigated the correlation between the pandemic era and seeking cosmetic surgery while focusing on the psychological impact of the pandemic on body-image perception. An anonymous web-based poll was distributed through social networks in Italy and the UK to patients seeking cosmetic surgery. The questions gathered responses on: 1. patient demographics; 2. cosmetic procedures requested; 3. motivations; 4. delays to cosmetic surgery caused by the pandemic; 5. pandemic effects on mood; 6. influence of video conferencing on body-image perception. A total of 159 respondents completed the online poll. Patients were more inclined to undergo cosmetic surgery during the pandemic citing the wish to improve their "lockdown face" (61%) and also the benefits of home recovery during smart working (36%). Eighty-one percent of respondents stated that video conferencing had impacted on their body-image perception, 95% indicated lower mood due to backlogs and surgery delays, while 72% of participants noted declined body-image perception during the pandemic. Data suggest that although video conferencing appears to play a key role in rising requests for cosmetic surgery consultations, a patient's negative self-perception is also likely linked to the psychological impact of the pandemic on mood levels.

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
