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
Parametric study of the seismic vulnerability of steel structures and their vulnerability curves
Get PDFThe use of metal structures is increasingly used. This is due to the fact that these structures are quick to erect (saving time and money) and make it possible to obtain interesting technical characteristics (spans and heights). These structures can be built in seismic zones and therefore despite their ductility can be damaged. This aspect has been very little addressed. Therefore, it is proposed within the framework of this study to investigate the seismic vulnerability of steel structures using the "vulnerability index" method. Parameters having an influence on the seismic behavior of steel frames were identified and then weighting coefficients for these parameters were calculated using the "Push-over" method. To do this, finite element models were developed and vulnerability classes were defined. Damage probability matrices and seismic vulnerability curves as well as a classification of metallic structures according to their vulnerability were developed. Validation and application cases have been processed and the obtained results are in adequacy what observations made in situ
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
Assessing fragility functions of unreinforced masonry buildings
No full textThe seismic vulnerability entrenched within the historical urban landscapes of
Algeria serves as a poignant reminder of the pressing need for comprehensive risk
management strategies, particularly concerning low and medium height
unreinforced masonry (URM) structures. These architectural gems, rich in cultural
significance, stand as tangible embodiments of Algeria's storied past. However,
their susceptibility to seismic disturbances presents an immediate threat,
demanding meticulous attention and innovative methodologies for effective risk
assessment and mitigation. In a pioneering scholarly pursuit, this research
embarks on an ambitious exploration, melding fragility functions and a
sophisticated vulnerability index method to unravel the intricate tapestry of seismic
risk assessment. Through the lens of fragility functions, the study delves into a
nuanced analysis, probabilistically delineating the vulnerabilities entrenched within
the complex framework of URM buildings. Furthermore, the meticulous derivation
of vulnerability functions via the vulnerability index method enhances the
granularity of risk assessment, providing a multifaceted perspective to discern
vulnerabilities accurately. Central to this investigation is the Belouizdad district, a
microcosm of historical significance nestled within the vibrant metropolis of Algiers.
By scrutinizing seismic scenarios spanning a spectrum of intensities (ranging from
VII to X), the study orchestrates a symphony of empirical data and analytical
prowess, unraveling the potential seismic reverberations poised to impact the
district's architectural heritage. In essence, this scholarly endeavor transcends the
confines of mere academic pursuit, serving as a guiding light illuminating the path
towards tailored seismic reduction policies. It stands as a clarion call to safeguard
Algeria's architectural patrimony, fostering resilience amidst the tremors of uncertainty and ensuring the preservation of its cultural legacy for generations to
come
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
