David Keeling: Inside Out
No full textResearch Background Inside Out focused on the major conceptual themes of Australian artist David Keeling. The key subject matter included landscape, architecture and humankind’s territorial positioning within the environment. The exhibition included several of Keeling’s early landscapes that explore the nature/culture dichotomy, the politics of the contemporary environmental debate and its connection to history contrasted with and alongside several more recent works that deal with particular locations and the exploration of interior/exterior spaces. By including several older works alongside a series of his most recent paintings we were able to review and contrast Keeling’s creative output and relevance across three decades of artistic practice. Research Contribution David Keeling’s artworks are a powerful communicative voice in the development versus conservation debate, especially within the Tasmanian context. The Inside Out exhibition enabled us to critically analyse the gradual refinement of his thinking, the maturity of his philosophical narrative and the creative methodologies utilized by Keeling to argue his environmental positioning. For Keeling the location of built architecture within the natural environment is a prosaic drama that implicates human kind in the destruction, entanglement and subjection of the landscape. Research Significance The significance of this research highlights and articulates a contemporary political understanding and location of place and the built environment within Tasmanian and Australian society. Keeling in the exhibition Inside Out was not only questioning our ownership of the land, but significantly, our custodianship of the natural environment. The research offered a summary of Keeling’s environmental concerns, influences and the development of his personal oeuvre as specific to these conceptual themes
Charles David Keeling 1928-2005 - Pioneer in the modern science of climate change. Obituary
No full textNumerous records now show how we humans are altering the planet, with potentially global consequences for climate. But the first and now iconic examples of documenting global climate change were the precise measurements of the concentration of carbon dioxide in the atmosphere made at the mountain station on Mauna Loa, Hawaii, by Charles David Keeling. If the world today realizes that it has a problem and needs to curb emissions of greenhouse gases, it in large part owes this knowledge to Keeling's painstaking efforts
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
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
Slow reception and under-citedness in climate change research: A case study of Charles David Keeling, discoverer of the risk of global warming
No full textThe Keeling curve has become a chemical landmark, whereas the papers by Charles David Keeling about the underlying carbon dioxide measurements are not cited as often as can be expected against the backdrop of his final approval. In this bibliometric study, we analyze Keeling's papers as a case study for under-citedness of climate change publications. Three possible reasons for the under-citedness of Keeling's papers are discussed: (1) The discourse on global cooling at the starting time of Keeling's measurement program, (2) the underestimation of what is often seen as "routine science", and (3) the amount of implicit/informal citations at the expense of explicit/formal (reference-based) citations. Those reasons may have contributed more or less to the slow reception and the under-citedness of Keeling's seminal works

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
