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
Moving Forwards Sustainable Urban Resilience and Cultural Heritage Conservation Through Modelling Environments
No full textThis article provides an in-depth overview of 2D and 3D Computer Aided Design (CAD), with a focus on Autodesk’s AutoCAD. Covering both 2D structural design and the three-dimensional environment, it illustrates the importance of concepts such as layers, 2D element management and the use of blocks. The transition to AutoCAD 3D includes orthogonal views, visualisation styles and the creation of solids. Subsequently, the BIM (Building Information Modeling) methodology with Revit software is introduced, highlighting the creation of intelligent models for buildings. A specific case study illustrates the application of BIM to a washhouse in the municipality of Samo, with details on laser scanner and drone surveying, point cloud generation and 3D modelling in Revit. The article highlights the advantages of the BIM model in information management, structural and energy analysis, and project collaboration. It also links to the current focus on land management, emphasising the importance of advanced technologies, such as Geomatics, in environmental monitoring and heritage conservation, thus contributing to urban resilience
A Smart Green Strategy and Big Data Analytics for Mapping Land Use Changes
No full textIn the past few years, there has been a greater focus on monitoring, control, and prevention of land, especially in view of the clear territorial and environmental changes caused by climate change. Changing weather patterns pose significant threats to land, infrastructure, cultural assets, and urban resilience. Consequently, is heightened the comprehension of the importance of the significance of creating effective monitoring systems and preventive measures to protect and preserve the land, artefacts, and cultural heritage, in addition to technologies and tools for sharing the collected data. This includes utilising Big Data as source of information. Big Data is commonly understood to refer to large and complex datasets that are so massive or complicated that typical data processing programmes are incapable of processing them. The exspression “Big Data” frequently denotes the utilisation of predictive analytics, user behaviour analyses or other sophisticated data analytics methodologies approaches for extracting value from data, rather than a specific data set size. This is particularly accurate for the for the massive amounts of Earth Observation imagery transmitted daily by satellites in orbit around the Earth
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
