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
The Prosopography of Anglo-Saxon England
No full textThe Prosopography of Anglo-Saxon England is a relational database accessible on line and free of charge at www. pase.ac.uk. It contains information on all the people who are known to have lived in or have been in contact with England between 597 and 1042. It is based on information contained in all the surviving written sources dealing with the same period. F. Tinti was the only member of the PASE team who worked full time for the Project, which she joined as Postdoctoral Research Officer in July 2000. Together with David Pelteret she collaborated with the technical officers on the construction of the data-collection database. She examined and entered prosopographical data from several Anglo-Latin works, including Bede’s Ecclesiastical History, the Lives of Cuthbert, the Lives and correspondence of the English missionaries to the Continent and the tenth-century saints’ Lives. She analysed the papal correspondence with England and a number of other continental sources, including the Liber Pontificalis. Throughout the duration of the Project she maintained the guidelines for the PASE data entry. She also trained a number of graduate students at Cambridge and London to take part in the data collection and the editing process. In the final stages she edited and supervised the editing of several aspects of the database, including the factoids called Education, Personal Information and Event. She also collaborated with the graphic designer for the construction of the PASE website

No full textAssessment of the drill-and-blast related overbreak in the BBT system
No full textDrill-and-blast is the common conventional tunnelling method in hard rock conditions. This paper analyses the characteristics of the blasting-induced overbreak in some of the tunnels of the Brenner Base Tunnel (BBT) system, in order to evaluate its correlation with the main geometrical and technical parameters of the excavation as well as the geomechanical properties of the rock mass. In particular, starting from Terrestrial Laser Scanning measurements and direct overbreak observations, it was possible to distinguish so-called geological overbreaks (due to the pre-existing discontinuities in the rock mass) from technical ones (related to the appropriate performance of the excavation technique) on the basis of the after-blasting presence of half-casts. Data were used to develop a multiparametric regression model based on the RMR index and length of the blast holes, recognized respectively as the main factors influencing the two mentioned overbreak types. Model parameters were initially calibrated over a portion of the Mules access tunnel excavated in micaschists and subsequently validated against experimental evidence collected along tunnels of different geometries driven through granite and paragneiss rock-masses. The overbreak model proved to successfully predict the correlation between overbreaks (especially that fraction related to the geomechanical characteristics of the rock-mass), RMR and length of the blast holes. As such, its preliminary application can provide a reliable first-assessment of extra costs and time during the design stage
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
Key Features of the Novel Geothermal Heat Exchanger Prototype Installed at the Brenner Base Tunnel
No full textThe design, installation, and testing of an innovative geothermal heat exchanger, tailored for tunnels
excavated by Tunnel Boring Machines, will be presented. The prototype was developed by the joint
efforts of BBT SE, involved in the construction of a new railway base tunnel system connecting Italy and
Austria, and the University of Bologna, engaged in applied research over various aspects of the BBT
system. The geothermal heat exchanger consists in a modular horizontal closed-loop system located in the
exploratory tunnel of the BBT system, specifically in the space dedicated to collect the drained water at the
lining invert. Due to the type of the heat exchange process, working with the drainage water, and for its
compact design and simple installation procedure, the prototype was called “Smart Flowing”. Modules were
built outside and later moved inside the tunnel, and eventually placed and assembled concurrently to the
advancement of the Tunnel Boring Machine. Specific tests were performed to prove the reliability and the
efficiency of the system, by simulating the work of a heat pump conditioning system in both heating and
cooling modes. Finally, a preliminary assessment of the economic and environmental potential of this
innovative prototype was carried out. First results showed the performance of the system for both heat
dissipation and extraction. The drainage water flow guarantees a continuous recovery to the natural state,
thus improving efficiency compared to classic geothermal heat exchangers. Economic savings and
reduction of pollutants and greenhouse gases, as compared to burning fossil fuels, can reach up to 70%
