What's new? Democracy, politics and the role of the media
No full textCitizens need to be informed to participate in democracy -- and they rely on the media for information.
Three recent books catalogue the problems with the contemporary media, and show just how much needs to change for the democratic role of the news to be fulfilled.
In Australia, would-be reformers confront a dangerous level of media ownership concentration, declining investment in costly citizenship-focused information gathering practices, and audiences whose tastes have been cultivated in soft entertainment.

Sharing News Online: Commendary Cultures and Social Media News Ecologies, Fiona Martin and Tim Dwyer (2019)
No full textPublishing a book that tackles the sharing of news content through social media channels is brave. As most media researchers acknowledge, change in the media industry is not so much constant as there is a constant iteration of compositions of relations that may exist for weeks or years and then are displaced again with yet other relations and practices. Yet, running through these emergent practices and complicating it further are remediated media forms and consumer habits developed in earlier eras. Sharing News Online: Commendary Cultures and Social Media News Ecologies by Fiona Martin and Tim Dwyer, and individual chapters co-authored with an assortment of their research partners, valiantly grapples with the series of challenges this presents. Their stated goal is to better understand the how and why of what we share as a part of everyday media practices. Across the ten chapters, they stake out some of the key challenges for media researchers and professionals alike, with some key contributions relevant for journalism studies
Content, consolidation and clout: how will regional Australia be affected by media ownership changes?
No full textThe government has released its proposed media law reforms, and its regional Australia that stands to lose the most. Tim Dwyer, Derek Wilding, Helen Wilson and Simon Curtis examine four regional locations – Wollongong, Townsville, Launceston and Toowoomba – and find that residents have few sources of local news, and many are angry at the poor quality and lack of coverage of major events. Yet the government’s proposed media diversity test would allow further and significant consolidation in all four locations. This report also reviews media ownership and local content in Australia, New Zealand, Canada, the US and the UK. A detailed summary is available online
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
