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
Assessment of an indicator of community appreciation of biodiversity. Data package for the Biodiversity Indicator Program: First assessment
No full textThis data collection contains the data, processes and descriptions of workflows required to produce the community appreciation of biodiversity indicator, as used in the NSW Biodiversity Indicator Program Report card: Community appreciation of biodiversity, Supplement to the NSW Biodiversity Outlook Report, first assessment. The data set and analysis draws on the 2015 iteration of the ‘Who cares about the environment’ survey conducted by the Social Research Centre (a subsidiary of the Australian National University) on behalf of the then NSW Office of Environment and Heritage (OEH). Although not developed to measure Community appreciation of biodiversity, the survey included questions that were related to biodiversity that could be used to measure the indicator dimensions, that is, cognitive, affective, and behavioural appreciation of biodiversity. Details of the development of the Community appreciation of biodiversity indicator and the baseline test of it are available in ‘Assessment of an indicator of community appreciation of biodiversity’ technical report. See related links to these publications. \nLineage: The data set and analysis draws on the 2015 iteration of the ‘Who cares about the environment’ survey conducted by the Social Research Centre (a subsidiary of the Australian National University) on behalf of the then NSW Office of Environment and Heritage (OEH). Further information about the 2015 iteration of the ‘Who cares about the environment’ survey is available in a technical report 'Surveying the environmental knowledge, attitudes, and behaviours of people in New South Wales in 2015' (DPIE 2021). The data was delivered to the research team as an SPSS file. The file is saved with the following name: 2015 Who cares data CAB indicator.sav. Analyses were conducted using SPSS software. Details about how the data was processed are given in the data lineage document that forms part of this data collection.

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
Is tree planting enough? Investigation of soil condition and composition of vegetation and invertebrate assemblages after ecological restoration in agricultural landscapes
Full text linkGlobally, vegetation clearing for agriculture continues to cause biodiversity loss and land degradation. Restoration efforts to increase biodiversity and remediate land degradation are often constrained by legacies of agricultural land-use. Active restoration is often needed to overcome abiotic and biotic thresholds to assist re-assembly towards a reference ecosystem.
My thesis explores the effects of active restoration on soil condition and re-assembly of plant and invertebrate communities. I coupled a global meta-analysis with a field survey and experimentation in the Western Australian wheatbelt to examine effects of active woody plantings on various ecosystem components.
In a field survey of 30 plots, I characterised soil chemical properties, vegetation and ant assemblages in three vegetation states: fallow croplands, 10-year-old planted old fields and reference woodlands. In addition, I experimentally tested whether the addition of woody debris to planted old fields can accelerate restoration outcomes, using a multi-site Before-After Control-Impact design.
Results show that at a global scale, restoration has positive effects on soil condition, but inconsistent trends for invertebrate species. Overall, recovery remains incomplete. These results were mirrored at a local scale. Whilst concentrations of some soil nutrients in planted old fields were more similar to woodland reference system than fallow croplands, key abiotic thresholds, in particular elevated phosphorus concentrations, persisted. Woody species richness and cover on planted old fields were also similar to reference woodlands, but herbaceous species richness and cover, and large woody debris amounts, remained similar to the fallow cropland. Ant assemblages responded positively to changes in habitat, with increases of species richness and abundance of key functional groups, however full convergence to reference conditions was not observed. Addition of woody debris to planted old fields had few significant effects on soil chemical and biophysical properties and community re-assembly.
Overall, results show that soil condition, vegetation and invertebrate assemblages on planted old fields responded positively to restoration efforts, however, recovery remains incomplete. Future research should test the efficacy of additional restoration practices beyond tree planting and focus on identifying suitable functional groups of invertebrates to assess restoration outcomes
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
