Il telerilevamento per l'osservazione del territorio dalllo spazio - La Provincia di Salerno dal satellite.
No full textIl contributo analizza le caratteristiche geomorfologiche e i livelli di antropizzazione della provincia di Salerno attraverso le immagini satellitari. Alcuni ingrandimenti riguardano la Costiera Amalfitana, il porto di Salerno, un tratto di costa del Cilento. L'evoluzione del territorio emerge attraverso l'analisi comparata e diacronica di tali immagini da remote sensing con uno stralcio della carta del Rizzi Zannoni (1812) e delle carte topografiche IGM (1908, 1998)
Remote sensing and interdisciplinary approach for studying volcano environment and activity
No full textRemote sensing (RS), also known as “Earth Observation (EO)”, is a well-established methodology for multidisciplinary applications and represents a neuralgic tool both for research and didactics, since it makes it possible not only to obtain very useful and interesting data and information but also to implement and make use of an integrated approach for collecting inputs from different sources, processing and interpreting them and presenting the results through a variety of multimedia outputs. That is obviously true also in the case of volcanic environments and activities, in the quiescence, activity and post-event phases. During the last years, the applications of satellite and aerial images, generated from data acquired in different spectral bands, namely in the visible, infrared and microwave parts of the electromagnetic spectrum, have enormously increased. Thus, in this paper, after a brief framework about some basic elements of remote sensing, we above all provide a literary review, underlying some important examples which permit us to develop interdisciplinary approaches and to highlight different fields of application. Then, after having provided some input in a didactic perspective, we synthetically describe the main peculiarities and kind of activities that characterise some volcanoes, for which the European Space Agency (ESA-ESRIN) has provided relevant images. Then, for each volcano, we propose an interpretive analysis of these images, supported by the previous explanations, in order to propose a possible scheme of referral and some guidelines to define a geographical and interdisciplinary framework aimed at showing new didactic and research horizons, where theoretical, methodological and applicative knowledge and skills converge, collaborating in a socially useful operative field
Remote sensing and interdisciplinary approach for studying glaciers
No full textRemote sensing, which provides interesting input and approaches for multidisciplinary research and wide inventories, and which represents a very important tool in the strictly related fields of research and didactics, shows great potentialities in the specific area of the studies of glaciers (extension, balance and variations),
glacier morphology and climate changes. In time, remote sensing applications for the analysis of glaciers and climate change have considerably increased, using different methodologies and obtaining significant results. In this paper, after a synthesis of some basic elements, we provide a detailed literary review, which sets out to underline the steps and results achieved and also to stimulate didactical considerations and hypothesis of work.
Successively, we resume the main characteristics of specific glaciers, for which the European Space Agency (ESA-ESRIN) has provided images ad hoc and for each glacier we propose an interpretative analysis of these images. According to the scheme proposed by Fea et al. (2013), the principal aim is to define research of referral and some interpretative guidelines useful for interdisciplinary frameworks focussed on glaciers, where
geography can play the role of collector between different sciences with the support of various geotechnologies
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
