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
Climate change and emerging risks. Innovative urban climate services as a strategy to improve resilience of human systems.
Get PDFClimate change and extreme natural events are increasingly threatening human systems. Even if greenhouse gases emission were reduced to zero today, global warming and the consequent climate change would continue to affect future generations: as climate is changing, human systems must learn to adapt. This study focuses on the role, the use and the management of climate information to overcome the barriers to climate change adaptation action. The article first addresses the relationship between sustainable development and climate change, regarded as “two mutually reinforcing sides of the same coin”. After a short section on the complementarity of mitigation and adaptation strategies, it analyses the barriers to investments in climate adaptation action by public authorities: the uncertainty about the magnitude and the frequency of climate change-connected events, the common wrong perception of unlikelihood of global warming consequences and the intrinsic complexity characterizing human systems are identified as major constraints. These considerations lead to introduce the concepts of soft- resilience and low-regret adaptation strategies. The discipline of climate change adaptation based on soft-approach climate resilience strategies is closely linked to information management, information technologies, communications, logistics, geographic information services and good governance. Indeed, information management is here seen as the pillar of soft-approach strategies. Low-regret strategies are defined as measures that would generate net social and/or economic benefits both under current climate and a range of future climate change scenarios. Section 5 explores potential synergies between Climate Services (understood as any service, equipment, techniques, practical knowledge and skills that can be used to increase climate resilience of human system) and Urban Facility Management services. This study identifies Innovative Urban Climate Services, an integrated system of services addressing both climate and urban issues simultaneously, as an effective, soft-approach and low-regret strategy to overcome the barriers to adaptation action. These solutions provide a general framework allowing a flexible and customized support for human systems in adapting to unavoidable impacts of climate change
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
Istituzioni monetarie nelle politeiai di Sicilia e Magna Grecia
No full textSeveral fragments from the aristotelian politeiai of Magna Graecia and Sicily regard metrological aspects connected with constitutional matters of some greek poleis (Syrakousai, Tarentum, Akragas, and Himera). Two passages from Pollux Onomasticon (IV 173-175, IX 79-82), a scholium on Iliad V 576, and the pseudo-aristotelian Oeconomicus 20c, and 20h, suggest that these references to money in the aristotelian politeiai could be connected with monetary reforms – a key element in the life of a polis, as Athenaion politeia 10 shows, and that in such contexts money should have had a sharp political value
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
