Fragile Territories Around Cities: Analysis on Small Municipalities Within Functional Urban Areas
No full textAlthough many disadvantaged areas are remote and isolated, the others are close to dense urban areas. Then, these peri-urban areas are both peripheral and fragile and, often, they are fringes from urban areas, where the well-known urban-rural mix occur.
In recent years, the most fragile urban areas have experienced growing attention. Through the years policymakers have tried to face territorial disadvantages with the help of funds.
Law 158/2017 is one example. The Law proposes twelve criteria to identify and then select small municipalities to support. In 2020 a research proposed to convert Law’s criteria into indicators. Combinations of indicators can identify different conditions of fragility. These combinations are useful starting point for further studies on small municipalities.
The present work uses data from the mentioned research for focusing on peri-urban areas. The case study is composed of small municipalities within three Functional Urban Areas (FUA) in Central Italy: L’Aquila, Perugia and Terni. Then, the paper points out the relationship between indicators of fragility and peculiar features of these areas
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

Full text linkOn the ecological network functional structure, the National Parks undoubtedly
represent core areas that play a key role on the biodiversity conservation strategies. The Italian National Parks system is characterized by the historic settlements presence, which represents a territorial peculiarity. On the one hand, this
characteristic contributed to maintaining an enormous wealth of biodiversity
and landscapes while, on the other hand, it strongly quickened the anthropic disturbance with certainly not negligible effects on the ecological connectivity. The
years of intensive urban growth coincide in Italy with a period of almost stasis
environmental legislation condition. Furthermore, the land planning penalized
both by a lack of strategic vision and by the absence of a clear planning and programming framework. The main aim of this work is to highlight the conditions
of presence of high pressures (derived to urban and infrastructural systems) and
high environmental values by directional proximity analysis. It will be implemented a new effective indicator to highlight conflicts between the phenomena
of urbanization and ecological values still present. This approach could permit
to address the land planning future choices both at territorial and local scale in
a perspective biodiversity conservation and mitigation of the anthropogenic impact on the National protected areas system
Marginality Assessment: Computational Applications on Italian Municipalities
Full text linkInner areas are the most peripheral Italian municipalities and they are characterized by clear loss of both public and private services. They represent one of the relevant elements in national and regional planning policy and the Italian government has made available a fund (€ 100 million) for small municipalities up to 5000 inhabitants (Law n. 158/2017). These areas have gradually seen an evident process of marginalisation, which is difficult to evaluate because it is the result of several factors. This work describes an applied methodology for this marginality assessment on the Italian inner areas, which was developed through the quantification of eight criteria selected from Law n. 158/2017. The analysis carried out two different simulations for elaborating and mapping territorial disadvantages, with the use of GIS software and MATLAB. The analysis highlights an evident clustering in specific geographic areas. Moreover, this result confirms that there is a significant chaining of some typical issues of the small municipalities. This research represents a first analytical approach to evaluating the intervention priorities of regulatory instruments and national strategies and it is proposed as an innovative approach that introduces a profound change of attitude moving from an equality-based model to an equity-based model

No full textVariations 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
