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
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
Geomorphic rehabilitation in Europe: recognition as best available technology and its role in LIFE projects
No full textGeomorphic rehabilitation ([GR], also known as geomorphic reclamation or geomorphic restoration) is a general term to describe alternative methods and procedures to conventional mine rehabilitation. The main aim of GR is to replicate ‘natural’ landforms for the new conditions after mining and to restore functionality and diversity of ecosystems at degraded sites. The correct application of the GR technique ensures visual integration with surrounding landscapes. Although GR is a broad term, referring to any geomorphic restoration of land, GR is often synonymous with fluvial GR, mostly following the GeoFluvTM-Natural Regrade method. This paper describes how and why the application of GR through GeoFluv-Natural Regrade in Spain since 2009 has attracted formal recognition by the European Commission (EC) of the European Union (EU) as one, among others, of a catalogue of best available techniques (BATs) for the management of waste from extractive industries, in accordance with the European Directive 2006/21/EC. GR has been recognised as BAT at the EU for multiple reasons, including mine site monitoring results that demonstrate increased physical stability with minimised erosion from stormwater and snowmelt runoff; natural hydrological function being established; the variability within the formed landform promotes ecological diversity for vegetation and wildlife communities; construction and short and long-term maintenance and repair costs are minimised; and visual impact of the mined landscape is reduced. This paper describes also the role of GeoFluv-Natural Regrade GR in the L’Instrument Financier pour l’Environnement (LIFE) program, which is the EU’s most important funding instrument addressing environment and climate action. A focus is provided on the LIFE TECMINE project, described in detail, since it is the most recent and complete GeoFluv-Natural Regrade example in Europe. The TECMINE project is a geomorphic-based ecological restoration project in the Valencia province, within the Iberian Mountain Range and where conventional mine rehabilitation practice, based on gradient terraces, shows general and widespread failure. The demonstration project is fostered by the Administration of the Valencia Region, which seeks to test innovative techniques (GR, micro-catchments, soil amendments and new protocols of revegetation) for mine rehabilitation, promote improved practices and disseminate the best practice output through their development and analysis. Testing GR is the main focus of the project. The application of GR at the TECMINE project included (a) finding ‘natural’ and ‘stable’ landforms and landscapes to be used as reference or analogues for replication in GR, although difficult, was possible due to ancestral land transformation; (b) the steep terrain, characteristic of the Iberian Range, challenged the formation of GR GeoFluv-Natural Regrade designs, but the project demonstrated that they can be implemented in that mountain setting; (b) the mining company reported similar cost estimations for this alternative GR rehabilitation (as-built) as that for a conventional restoration design (projected); (c) a holistic approach to GR, not dealing only with topography, allowed the identification and use of limestone colluvium as an adequate growth media for initiating soil development; this solution not used before for rehabilitation in this region provided a clear and advanced contribution from the project.European CommissionDepto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEpu

Mine Closure 2019 Volume II. Proceedings of the 13th International Conference on Mine Closure
No full textThe Thirteenth International Conference on Mine Closure returns to Perth, Australia where it was first held in 2006. Since then Mine Closure has become a necessary focus of mining and, with a global revival in the mining industry, the topic of Mine Closure is now more relevant than ever. Minimising financial costs while satisfying stakeholder expectations and achieving sustainable closure are now considered essential in planning the mining process. The material to be presented at this year’s Mine Closure conference, and the information contained in the conference Proceedings will provide assistance to owners, operators and consultants who are currently facing the challenges of managing, or planning for, closure of mines. The themes covered in this year’s conference once again deal with key, perennial issues such as planning and financing mine closure with consideration of issues such as community engagement, rehabilitation and remediation providing key topics. Fundamental matters such as how to achieve much sought after relinquishment, and the vexing issue of how to deal with and manage legacy sites along with concerns of ongoing liabilities are all considered in the conference and these proceedings. The section on stakeholders and community engagement emphasises the priority that ever more companies are giving to considerations of social performance. Finally, a number of well documented Case Studies provide information on how specific and sometimes unique challenges have been addressed. The information contained in the Proceedings contains information and ideas that will be of continuing interest and use by planners, designers, contractors, operators, owners and regulators alike. In a rapidly evolving field such as Mine Closure, the benefits of having a truly international representation of delegates, such as at Mine Closure 2019, is evident from the quality and variety of topics covered in these Proceedings
