Assessing geomorphosites used for rock climbing. The example of Monteleone Roccadoria (Sardinia, Italy)
No full textAbstract
Within the framework of assessing geomorphosites and their tourism potential, a new field of research has opened up, focusing on sites used for outdoor activities, like free climbing. This line of research in particular focuses on the suitability of geological and geomorphological characteristics of a specific site for a particular sport. Concentrating on geomorphological hazard, rock quality, tourism capacity and site vulnerability, a method of assessment was designed and tested on a number of important Italian climbing sites. Using the results of the Monteleone Rocca Doria (Sardinia, Italy), the article presents the proposed approach of assessment. Although the site in question is recognised for its scientific, aesthetic and cultural value, it has drawn attention for its attractiveness for rock climbers in particular. Thus, the aim of the assessment was to support management of the site by proposing options for utilisation that are sensitive to both the needs of the climbers and the environment in which the site is embedded. In particular, attention was given to potential geomorphologically-related risks for climbers, the impacts linked to human presence and the specific characteristics of the geomorphosite
Advanced imaging of gliomas
No full textGliomas are the most common in primary malignant Central Nervous System tumors arising from glial cells in a global scenario where breast cancer is the highest-incidence cancer. They represent a very heterogeneous group but astrocytomas have the biggest incidence among all. Taking in account the newest standards in treatment, determining molecular and histopathological patterns is actually considered imperative to get the best management for pathology and its best outcome. Imaging plays a key role in all the steps of the diagnostic pathway, from diagnosis to treatment and in follow-up, also being essential in defining prognosis. Conventional gadolinium-enhanced Magnetic Resonance and particularly its new Advanced techniques (diffusion, perfusion, spectroscopy), definitely have been recognized to represent leading. Imaging modalities in both of initial patients’ work-up and in follow-up, also if some limitation is present, such as a not completely and satisfying discrimination between high and low grade gliomas and/or between disease recurrences and physiological post-therapy changes and in fact MRI is today the most sensitive and accurate method of imaging in many fields of diagnostics. Other novel hybrid Imaging modalities (PET/MRI) were found to be very interesting during patients follow-up, thanks to their high sensitivity and specificity in detecting any kind of post-treatment tissue change and also in evaluating prognosis. Aim of this work is to highlight all the leading Imaging modalities that actually give the best chances in diagnostic pathways of gliomas, pointing out potentialities and limitations of any technique, also in the light of new frontiers that Artificial Intelligence offers

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
