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
Expeditionary warfare in the age of global terrorism: a critical assessment of Britain's war against Al Qaeda
Full text linkThe war against Al Qaeda and its allies may well become the defining conflict of our age. Certainly it is cited as evidence of a transformation of war that is sweeping away older modes of warfare. This paper seeks to explain the reasons for the failure of the military campaign so far, but looks at this debate from the perspective of the British rather than the American experience of the war on terror.
This paper was presented as part of Rethinking the Postcolonial in the Age of the War on Terror joint symposium, by the MnM Centre in conjunction with the UNESCO Chair in Transnational Diasporas and Reconciliation Studies, at the University of South Australia, on 16 and 17 September 2010. The aim of the symposium was to explore the postcolonial condition in the era of the \u27war on terror\u27 and to rethink postcolonialism in order to reformulate or reinforce its critical insights.

Opening the floor for discussion: A perspective on how scholars perceive attitudes to science in policymaking in South Africa
Full text linkCITATION: Czachur, M. V. et al. 2021. Opening the floor for discussion : a perspective on how scholars perceive attitudes to science in policymaking in South Africa. South African Journal of Science, 117(1/2):7948, doi:10.17159/sajs.2021/7948.The original publication is available at https://sajs.co.zaPolicymakers are a vital group with whom scientific research should be communicated, especially when
the reason for many research projects is linked to relevance for socio-political and economic management.
Science communication has a vital role in transforming research into policy, and a core element of this process
is understanding the target group, namely policymakers. Science and policy influence each other deeply, so
researchers and policymakers should improve their understanding of each other and of the processes involved
in both fields in order to better collaborate. Accordingly, an in-depth understanding of how scholars perceive
policymakers is a precondition for scientists to achieve any desired management and policy impacts.
In December 2019, six researchers and one research manager from Stellenbosch University, South Africa, gathered
to discuss their understanding of policymakers. The discussion was part of a Science Communication Masterclass
hosted by the South African Research Chair in Science Communication and Econnect Communication, Australia.
The purpose of the group discussion was to develop a science communication strategy that would enhance the
sharing of scientific research outputs with policymakers in South Africa. We explored five questions to help us
record our perception of policymakers: (1) Who do we think the policymakers are? (2) How do we think that
policymakers perceive research? (3) What concerns do we believe that policymakers have about research? (4)
What information do we think policymakers are interested in? (5) What forms of communication do we think
policymakers prefer?
This Commentary presents our view on how we think researchers perceive policymakers, as discussed in the
Science Communication Masterclass. We hope to initiate a discussion around science communication with
policymakers, and improve current practices.https://sajs.co.za/article/view/7948Publisher's versio
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
Multiple lithic clasts in lunar breccia Northwest Africa 7948 and implication for the lithologic components of lunar crust
No full textThis study presents the petrography, mineralogy, and bulk composition of lunar regolith breccia meteorite Northwest Africa (NWA) 7948. We identify a range of lunar lithologies including basaltic clasts (very low-titanium and low-titanium basalts), feldspathic lithologies (ferroan anorthosite, magnesian-suite rock, and alkali suite), granulites, impact melt breccias (including crystalline impact melt breccias, clast-bearing impact melt breccias, and glassy melt breccias), as well as regolith components (volcanic glass and impact glass). A compositionally unusual metal-rich clast was also identified, which may represent an impact melt lithology sourced from a unique Mg-suite parent rock. NWA 7948 has a mingled bulk rock composition (Al2O3 = 21.6 wt% and FeO = 9.4 wt%) and relatively low concentrations of incompatible trace elements (e.g., Th = 1.07 ppm and Sm = 2.99 ppm) compared with Apollo regolith breccias. Comparing the bulk composition of the meteorite with remotely sensed geochemical data sets suggests that the sample was derived from a region of the lunar surface distal from the nearside Th-rich Procellarum KREEP Terrane. Our investigations suggest that it may have been ejected from a nearside highlands-mare boundary (e.g., around Mare Crisium or Orientale) or a cryptomare region (e.g., Schickard-Schiller or Mare smythii) or a farside highlands-mare boundary (e.g., Mare Australe, Apollo basin in the South Pole–Aitken basin). The distinctive mineralogical and geochemical features of NWA 7948 suggest that the meteorite may represent lunar material that has not been reported before, and indicate that the lunar highlands exhibit wide geological diversity
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
