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
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
Monitoring forests in remote areas by IoT measuring systems: the RemoTrees project.
No full textForests ecosystems play a fundamental role in mitigating global warming and associated increasing climatic variability through the feedback of their carbon and water cycles on the global climate system, while being increasingly exposed to dieback and natural disturbances triggered by extreme climate events. The absence of a comprehensive in situ forest monitoring network, particularly in remote regions characterized by strong logistic limitations, poses challenges in tracking forest responses to climate change. Recent strides in IoT technology, satellite IoT connectivity and energy harvesting systems present promising opportunities for the development of novel devices and set-ups for field observations in forest environments. On that note, the EU-funded RemoTrees project (Horizon Europe Research and Innovation Programme under Grant Agreement No. 101086287) aims to design and build an innovative, autonomous in-situ monitoring system suitable for remote forest areas also under extreme physical conditions and able to provide data via satellite communication to a dedicated platform. In this framework, RemoTrees will provide observations of Essential Climate Variables (ECVs) and other key variables including fraction of absorbed photosynthetically active radiation (fAPAR), multispectral measurements of incident, canopy reflected and transmitted solar radiation, tree stem radial growth and motions, sap flow, soil temperature and moisture, besides air temperature and humidity below and above the forest canopy. The resulting data set will be integrated with Earth Observations for the development of use cases on the impact of climate change on forests, demonstrating its usability as a reference for remote sensing products calibration and validation as well as the interoperability and synchronization between in-situ and remote sensing systems according to GEOSS requirements
Clonidine treatment for agitation in children after sevoflurane anesthesia.
No full textClonidine is effective in treating sevoflurane-induced postanesthesia agitation in children. We conducted a study on 169 children to quantify the risk reduction of clonidine agitation in patients admitted to our day-surgery pediatric clinic. Children were randomly allocated to receive clonidine 2 mug/kg or placebo before general anesthesia with sevoflurane that was also supplemented with a regional or central block. An observer blinded to the anesthetic technique assessed recovery variables and the presence of agitation. Pain and discomfort scores were significantly decreased in the clonidine group; the incidence of agitation was reduced by 57% (P = 0.029) and the incidence of severe agitation by 67% (P = 0.064). Relative risks for developing agitation and severe agitation were 0.43 (95% confidence interval, 0.24-0.78) and 0.32 (0.09-1.17), respectively. Clonidine produces a substantial reduction in the risk of postsevoflurane agitation in children
