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
Sustainability assessment of the repurposing of wind turbine blades
No full textIreland is regarded as rich in wind resources, with Wind Energy Ireland suggesting that wind generation could make Ireland a renewable superpower. Ireland has chosen to capitalise on this resource by dramatically expanding wind energy generation capacity. However, with this development of wind capacity comes the need to deal with increasing amounts of waste from the wind sector when the turbines reach end-of-life. While much of the turbine is recyclable, the blades, which are made from composite glass fibre and polymer material, is not yet economically viable to recycle. Many blades are being landfilled or incinerated at the end of their working lives. An option that is gaining in popularity is the idea of repurposing blades into useful structures.
This thesis considered the question “Can repurposing of end-of-life wind turbine blades from Irish wind turbines offer overall gains in sustainability?” Overall sustainability was by developing a Life Cycle Sustainability Assessment framework, which includes environmental Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and the lesser established social life cycle assessment (s-LCA). LCA was used to first establish co-processing of the discarded blade material in Ireland as the most likely and best case scenario against which to compare repurposing solutions. Three overall scenarios were then developed based on maximizing blade consumption, the substitution of high embodied carbon materials, and serving customer segments who will benefit from circular material use such as the county councils who may be required to adhere to Green Public Procurement requirements. Based on these scenarios and customer segments, an estimated 20% of the blade material estimated to be decommissioned in Ireland could potentially be repurposed, offering reductions of 30,780 kg CO2 equivalents of emissions per year. The concept of using end-of-life blades to make bridges (termed ‘BladeBridge’) was selected from the scenarios for an in depth study. LCA and LCC comparisons against a conventional bridge and the baseline disposal method, showed BladeBridge to be environmentally less impactful than both of these scenarios. From a cost perspective, the first BladeBridge using a specific blade model will be slightly more expensive than a conventional bridge and subsequent blade bridges due to the reverse engineering required to assess the residual structural properties of the blade. However, second and subsequent bridges made from the same blade models would be less expensive. Indicators for s-LCA were developed by considering national shortfalls in Ireland’s performance against the Sustainable Development Goals (SDGs), which can be considered the world’s key performance indicators. In this way, these indicators capture a product’s ability to affect global social indicators in which Ireland most needs to improve upon. Using LCA, LCC and the SDG based s-LCA indicators, a stage/gate screening process was developed which follows the embedded systems model of sustainability. In this framework, early business ideas can be first screened for environmental and social value, and then for cost viability. This framework can help in the development of ‘purpose driven businesses.’ The research presented in this thesis combined life cycle thinking with policy considerations and business value creation, and offers contributions across all of these areas. Some examples of contributions are the positioning of LCA in the repurposing debate; the creation of a framework for life cycle assessments of products made from end-of-life material that can be used to contribute to improving globally defined social and environmental metrics; analytical tools for local authorities to implement green public procurement; and support for Ireland to decouple its renewable energy generation from the production of waste
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
