Cyclical inversion of limits and centres : the formation process of the Regio quartadecima, Constantinople
Full text linkThe paper reconstructs the topography of Constantinople’s fourteenth region (regio XIV) applying the urban morphology analysis methods (Caniggia and Maffei, 1979) and the attractors’ theory (Camiz, 2018) to the fragmentary documental sources and scarce archaeological data. The pontem sublicium sive ligneum’s location was determined as part of a street network, in analogy with the pons sublicius in Rome, according to the formation process of the territorial organism. This was the starting point for the reconstruction of the topographic mosaic. By redefining the path of the Constantinian walls upon quantitative sources it was possible to localise the monumental buildings of the XIV region, as listed in the Notitia Urbis Constantinopolitanae, with reference to the morphology of the territory described by Dionysius of Byzantium and the Patria Konstantinopoleos. The form of the territory is a permanent element within urban contexts of continuous changes, demolitions and reconstructions. The analysis of the urban tissues, the road network’s diachronic attraction and the reconstruction of the territorial organism provided the general methodological framework for the placement of the topographical urban fragments mentioned by historical sources upon a GIS
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
Past and future hydrogeological risk assessment under climate change conditions over urban settlements and infrastructure systems: the case of a sub-regional area of Piedmont, Italy
No full textHydrogeological impacts due to flood and landslides are among the most significant disasters in the world. In the last decades, these events result in forthcoming losses of life and damages to private and public properties and criticalities increase due to very often increasing losses as consequence of changes in the rainfall regimes as well as the increase in average temperatures. This paper describes an applied hydrogeological risk assessment methodology carried out as part of an interdisciplinary European project between France and Italy (Interreg Alcotra ARTACLIM). We developed a practical framework to assess the risk of urban settlements and infrastructural assets within a sub-regional area of Piedmont (north-west of Italy). Past and future climate drivers are here analyzed using high-resolution data to highlight the temporal and spatial distribution of elements under threat. Using geographic information systems, we elaborate climate and socioeconomic data to develop an effective procedure for a sub-regional integrated research on the intrinsic and external conditions of potential instability. The results of the analyses produce a geo-localized risk score that can be used to rank assets in a screening process that aims to assist urban planner and local policymaker to prioritize the adaptation measures required for taking action to reduce hydrogeological damages to their assets
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
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
