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
Unlocking the Universe's Secrets with James Webb Space Telescope (Free Astronomy Public Lectures)
No full textThis is a special State of the Universe lecture for National Science Week in August 2022. Presented by the Centre for Astrophysics and Supercomputing (CAS) at Swinburne University of Technology.
Successfully launched on 25 December 2021, NASA’s successor to the Hubble Space Telescope, the James Webb Space Telescope (JWST) has taken its first images and will be released to the public 12 July. Join Professor Karl Glazebrook, Dr Themiya Nanayakkara and Dr Colin Jacobs, as they discuss these images and the potential secrets of the universe they reveal. Dr Nicha Leethochawalit from University of Melbourne will share her work on redshifted galaxies (z=10). Presented 19 August 2022
How you shaped the election
No full textThis election, online issues finally got the attention they deserve. And the situation is here to stay, writes Colin Jacobs of Electoric Frontiers Australia.

I\u27M NOT TALKING about which party had the most Facebook followers or made the most gaffes on Twitter (Julia Gillard and Family First, respectively). Serious issues around internet governance and our internet future came into play, and by all accounts will continue to be significant as the situation plays out this week.
The first issue that affected the election was Labor\u27s mandatory internet censorship policy, 3 years old and counting. Throughout that time, I believe the accepted wisdom amongst the scheme\u27s proponents - the most notable being of course Senator Conroy - was that it would be unpopular with a handful of geeks but would appeal to the wider audience of mums and dads in the electorate.
If this was indeed the strategy, I think it backfired. Although it\u27s based on mainly anecdotal evidence, I believe many internet users had their political consciousness awoken by this attempt to slap censorship on the country\u27s net connections. When this issue was important to people, it didn\u27t just put them slightly off-side, but made them hopping mad, if not lifelong skeptics of the ALP. Over time I have spoken to MPs and parliamentary staffers of all stripes, and I\u27m pleased to report that many people did indeed contact their elected representatives and let the opinions be known. For some MPs, this amounted to a veritable flood, and the issue was absolutely on their radar.
Unfortunately, we\u27ll never be able to quantify what this did to Labor\u27s vote. The fact is that Labor suffered a big swing against them, and it\u27s worth noting that most of this swing went to the Greens, the most vocal opponents of the filter in Parliament. At the ballot box, we can\u27t disentangle the filter from other issues such as climate change and refugees that the Greens campaigned on, but I believe the filter played a big role.
The Coalition, of course, decided to oppose the filter themselves, and this didn\u27t happen until the election campaign was already underway. Once again, from reading the feedback online, there\u27s some evidence that this gave their campaign a boost amongst Australia\u27s netizens. The fact that they decided to make an announcement then, rather than wait for the legislation as they had previously indicated, shows that they thought this was the case as well.
So while I wouldn\u27t want to oversell it, internet users are hardly a minority in Australia, and issues close to their hearts are at getting more attention than ever before.

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
