Tecniche di Visualizzazione a supporto dell'analisi dei dati in FAIRWIS
No full textIl lavoro descritto in questo articolo è relativo al progetto FAIRWIS (Trade FAIR Web-based Information Services) il cui scopo è quello di costruire un sistema che offra servizi innovativi on-line per supportare l’organizzazione e la gestione di fiere reali e virtuali. Il sistema che si sta sviluppando è per molti aspetti diverso dai vari siti Web disponibili attualmente per varie fiere; in particolare, i dati forniti da questi siti non sono organizzati in un modo integrato e omogeneo e vengono di solito presentati in uno stile rigido e non facilmente modificabile. Inoltre, questi siti generalmente utilizzano dati statici che sono difficili da aggiornare e da mostrare in un formato appropriato. FAIRWIS è connesso a un database per garantire la coerenza dei dati e il continuo aggiornamento. Questo articolo descrive uno specifico modulo di FAIRWIS che utilizza tecniche di visualizzazione di dati allo scopo di agevolare l’interazione utente-calcolatore, permettere un facile accesso ai dati memorizzati e mostrare in un modo appropriato le informazioni ritrovate, in modo da supportare l’utente nell’analisi di tali informazioni
A quantitative and non-invasive vibrational method to assess bone fracture healing: a clinical case study
No full textOrthopaedics needs a robust diagnostic tool that can help or even replace traditional radiography in bone healing assessment, thus reducing patient exposure to ionizing radiation. We used a vibrational method to assess the healing of a complex fracture treated with external fixation, exploiting a quantitative and non-invasive procedure. Callus stiffening was monitored from the time of surgery until the fixator was removed. Our approach overcomes previous limitations and involves a longer period of healing monitoring (about 9 months), very frequent tests (bi-weekly), and the analysis of a single test configuration. The healing process was monitored by analysing the percentage increments of the squared resonant frequencies (SFIs), related to the stiffness variation and the changes in the frequency response functions. The results were validated by X-rays images, and revealed that the most sensitive parameter to quantify the healing was the SFI of the first resonant frequency which increased by about 20% per month during the formation of the woven callus and up to about 50% at the end of healing completion. This study confirms the potential of the vibrational method as an alternative to radiography in fracture healing assessment
The Quantitative and Monetary Impacts of Forest Fire Crimes - EFFACE REPORT
No full textWildfires have been recognized as one of the most significant environmental threats in Europe and particularly in the Mediterranean regions, giving rise to a multitude of environmental, social and economic impacts. However, forest fires are often not the result of a natural disaster or causes of fatality, but rather an anthropogenic phenomenon with direct dependence on social behavior, both voluntary and involuntary. Therefore the willful and malicious burning of forests represents a fire crime. This report focuses on the current status of wildfire impacts at the European and Italian regional levels, looking mainly at fire crimes in both quantitative and monetary terms and, to the same extent, at the relation between geographical distribution of such crimes and organized crime
On the Use of Sentinel-2 NDVI Time Series and Google Earth Engine to Detect Land-Use/Land-Cover Changes in Fire-Affected Areas
Full text linkThis study aims to assess the potential of Sentinel-2 NDVI time series and Google Earth Engine to detect small land-use/land-cover changes (at the pixel level) in fire-disturbed environs. To capture both slow and fast changes, the investigations focused on the analysis of trends in NDVI time series, selected because they are extensively used for the assessment of post-fire dynamics mainly linked to the monitoring of vegetation recovery and fire resilience. The area considered for this study is the central–southern part of the Italian peninsula, in particular the regions of (i) Campania, (ii) Basilicata, (iii) Calabria, (iv) Toscana, (v) Umbria, and (vi) Lazio. For each fire considered, the study covered the period from the year after the event to the present. The multi-temporal analysis was performed using two main data processing steps (i) linear regression to extract NDVI trends and enhance changes over time and (ii) random forest classification to capture and categorize the various changes. The analysis allowed us to identify changes occurred in the selected case study areas and to understand and evaluate the trend indicators that mark a change in land use/land cover. In particular, different types of changes were identified: (i) woodland felling, (ii) remaking of paths and roads, and (ii) transition from wooded area to cultivated field. The reliability of the changes identified was assessed and confirmed by the high multi-temporal resolution offered by Google Earth. Results of this comparison highlighted that the overall accuracy of the classification was higher than 0.86
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
