Gregory Phillips: should Australian cities bear Indigenous language names?
No full textOverview
How can we achieve a deeper understanding of Australia’s Indigenous history – not just in the abstract, but in the specific contexts of where we live, work and play? If all Australians had a relationship with Indigenous language, how would that affect race relations more broadly? Medical anthropologist and Aboriginal health advisor Gregory Phillips shares his view in a 30 minute snap lecture, plus questions.
 
Gregory Phillips on the Republic and Aboriginal peoples
No full textOverview: What should an inclusive, modern Australian nation-state look like? With Australians generally disengaged from the political system and Aboriginal peoples not properly included in the first place, the Republic movement is perhaps the perfect avenue to address some of these issues.
Anthropologist and lecturer in Aboriginal health Gregory Phillips argues that if we are to resolve the big picture concerns of sustainability (economic and environmental) and national identity (our place in the region and world), the viewpoints of Indigenous voters must be incorporated into the political conversation. In order to move forward and adopt a more inclusive and effective system of government that brings black and white voters into synchronicity, an Australian Republic must be considered as the most viable solution.
 
Scan4CFU: Low-cost, open-source bacterial colony tracking over large areas and extended incubation times
No full textA hallmark of bacterial populations cultured in vitro is their homogeneity of growth, where the majority of cells display identical growth rate, cell size and content. Recent insights, however, have revealed that even cells growing in exponential growth phase can be heterogeneous with respect to variables typically used to measure cell growth. Bacterial heterogeneity has important implications for how bacteria respond to environmental stresses, such as antibiotics. The phenomenon of antimicrobial persistence, for example, has been linked to a small subpopulation of cells that have entered into a state of dormancy where antibiotics are no longer effective. While methods have been developed for identifying individual non-growing cells in bacterial cultures, there has been less attention paid to how these cells may influence growth in colonies on a solid surface. In response, we have developed a low-cost, open-source platform to perform automated image capture and image analysis of bacterial colony growth on multiple nutrient agar plates simultaneously. The descriptions of the hardware and software are included, along with details about the temperature-controlled growth chamber, high-resolution scanner, and graphical interface to extract and plot the colony lag time and growth kinetics. Experiments were conducted using a wild type strain of Escherichia coli K12 to demonstrate the feasibility and operation of our setup. By automated tracking of bacterial growth kinetics in colonies, the system holds the potential to reveal new insights into understanding the impact of microbial heterogeneity on antibiotic resistance and persistence.This work was partially supported by the U.S. Defense Threat Reduction Agency (HDTRA1-15-1-0053) and U.S. National Science Foundation (NSF IDBR-1556370)
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
GALAs 2015: in five. A gala debate on 2020
No full textThis Wheeler centre talk discusses where will we be as a society in five years’ time.
Overview
As part of our fifth birthday celebrations, we presented a unique headline debate with two sides, just one team – and nothing less than our future at stake.
The central question: where will we be as a society in five years’ time? Should we feel hopeful, or should we feel despair?
In four minute bursts, our panel of five prominent thinkers each make an informed, impassioned case for optimism – and counter with an equally persuasive case against it.
It\u27s public debate of a kind that bucks binaries, marginalises myopia and penalises pigheadedness. And it’s a conversation with room for complexity, nuance and the grey areas in your grey matter.
Speakers include feminist author Eva Cox, Robogals founder and former Young Australian of the Year Marita Cheng, political journalist and author George Megalogenis, Tasmanian Department of Justice secretary Simon Overland and medical anthropologist Gregory Phillips. Our host is writer and broadcaster Annabel Crabb.
