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
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

In Doing less with less, CPD public service Research Director Christopher Stone contends that sometimes cutting can cost more than it saves. Shifting responsibility to the private sector is not a cost-effective strategy when the public sector is better placed to provide essential services. While efficiency is defined in terms of producing more with the same or lesser expenditure, and some politicians talk about doing ‘more with less’, arbitrary spending cuts can in reality simply mean doing less with less.
Recent budgetary imperatives to cut service provision underline the importance of careful and evidence-based decisions on where to cut and how. This second instalment of CPD’s three-part False economies report provides examples of where peremptory cuts would have led to increased costs as well as reduced performance:
In 2o11 Queensland spent 350 million, by using that capacity to keep public works costs low.
Doing less with less also highlights examples that cast doubt on the assumption that the private sector always does the best and most efficient job of delivering essential services, for example:
Detailed analysis by the Productivity Commission comparing public and private hospitals has shown that the efficiency of each is very similar, with both having areas of strength compared to the other.
The cases provide evidence that reducing government can be wasteful and inefficient. They are a warning that when cuts, privatisation, or outsourcing are considered, thorough and sophisticated analysis of the costs and benefits of such actions is necessary
False economies part 3: bang for our bucks

CPD’s public service research director Christopher Stone contends that despite rhetoric to the contrary, the Australian public sector is efficient.
Investigation of Australian public sector in terms of results against resources finds it to be more efficient than the public sectors of most similar nations. This means that our public sector does a good job of delivering essential community needs with minimal resource inputs, and is adaptable to changing circumstances.
This paper continues CPD’s False economies series by setting out evidence on the efficiency of our public sector. Internationally we stack up very well on efficiency:
Among OECD nations, Australia is the only one to be in the top ten most effective governments, but the bottom five lowest taxing governments. This is strong evidence that we have a far more efficient government than most of our peer nations.
The paper also points out that our public sector is as efficient as the private sector once the different responsibilities are taken into account. In general the harder jobs are left to public sector organisations, more is expected of them, and when this is factored in their performance is similar to that of private sector organisations.
This research builds on previous papers in the series: Decoding efficiency, which busts the myths surrounding the often-misconstrued term, and Doing less with less which gives detailed examples of how such misunderstandings can create waste.
The False economies series is pointing out that the way we discuss efficiency in public services is damaging the nation. The term’s misuse justifies poor and ill-considered policy approaches, which can actually drive inefficiency and waste, and distracts us from genuine efficiency improvements that can be made
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
