Landscape and Human Settlements in Rural Areas, a Diachronic Analysis Using Landscape Metrics and Topographic Indices. The Municipalities of Vico Equense and Sorrento, Sorrento Peninsula, Italy
No full textAbstract
Besides their primary function linked to agricultural activities, rural buildings have been for centuries also a distinctive element of the Italian landscape. The present study explores the intrinsic correlation between rural buildings and landscape, highlighting how the first ones shaped and/or were affected by the rural landscape. The study focuses on traditional and cost-effective architectures in a typical context of southern Italy, the Sorrento’ Peninsula, historically marked by small land properties with direct soil management, and nowadays subjected to various pressures: from housing to infrastructure, to tourism.
The landscape analysis covers about 60 years, starting from the Italian Touring club Land Use map (1960), until to the 2018 Corine Land Cover map . For the building analysis, data were retrieved from the topographic map of the Italian Military Geographical Institute (1957) and from the Regional Technical map of the Campania Region (2004–2005). This research critically examined rural systems, mapping buildings and connecting them to the surrounding landscape, basing on Geographic Information Systems (GIS) support, landscape metrics assessment and topographic factors analysis. The results showed significant transformations in landscape and rural settlements (−20% of agricultural areas; +30% of forest and semi-natural areas; +67 urban areas), highlighting the strong pressure to which the territory is subjected today due to land consumption.
The aim of the work is to support the landscape management and the policy makers activities to foreseen specific interventions to landscape protection and valorisation, considering both the historical building heritage and the local community development issues
Multi-temporal Analysis of the Urban Heat Island (UHI) Effect Using Satellite Imagery in the Phlegrean Area
No full textAbstract
Urbanization and the concurrent loss of green areas determine changes in land surface temperature (LST) and worsen the phenomenon of urban heath islands (UHI). To understand these relationships, long-term studies have been carried out using remote sensing data, analyzing the trend over a large area. This study is aimed at multi-temporal analysis based on satellite data for calculating LST and land use indices to identify their interaction with UHIs during the period 2000–2023, in the region known as Phlegrean Area, in Campania (Italy). Results reveal that the reference period was characterized by increasing LST which affected UHI share and intensity. On the other hand, we observed a contraction of greenery in favor of urban areas. Furthermore, in the same period of observation, it is noteworthy the loss of more than 3 km2 of forests due to a severe wildfire. In conclusion, the model results show that there could be a correlation between the increase in artificial surfaces and the increase in temperatures and consequently the enlargement of UHI areas. A greater attention in the design of green areas in urban contexts, considering sustainability and ecology targets, could help mitigating UHI phenomenon
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
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
