No full textFour atypical cases of misdiagnosed facial cutaneous sinuses of dental origin
No full textBACKGROUND: Odontogenic cutaneous sinus tracts are frequently misdiagnosed as cutaneous non-dental related pathologies, due to their lack of a typical morphology, their extraoral location, and the frequent absence of concomitant dental symptoms. An erroneous diagnosis may lead to long-lasting, invasive, and not resolutive surgical and medical treatments. METHODS: Four patients referred to our department lamenting the presence of a recurrent facial cutaneous sinus tract. They all had already had different wrong diagnoses and were treated with not resolutive therapies or surgeries. After a clinical and radiographical oral examination, the cutaneous fistulas were found to have a dental etiology, and the extraction of the compromised tooth was performed. RESULTLTS: One week after the tooth extraction, all the patients presented good healing of the intraoral mucosa. At the long-term follow-up in all four cases, the definitive closure of the extraoral sinus tract and a reduction of the scar was found. CONCLUSIONS: If a facial sinus tract is present, the odontogenic etiology should always be considered, since it can easily bring to the correct diagnosis, leading to a rapid resolution of the fistula. Once the dental origin has been confirmed, the suggested treatment for a conclusive resolution of the cutaneous sinus tract is the endodontic treatment or the extraction of the affected tooth
Multiscale geophysical investigation on the Budoia-Aviano thrust system (NE Italy): first results
No full textThe work group is involved in the framework of the PRIN2020 research project (NASA4SHA), which aims to identify the complexity of faults in active thrust systems in Northern Apennines and Southern Alps in Italy. The paper describes the application of a multi-scale geophysical investigations applied on the Budoia-Aviano thrust system, that is part of the Polcenigo–Montereale fault system. The investigated area, which is part of the external Plio-Quaternary front of the Eastern Southalpine Chain, is characterized by the presence of distinct WSW-ENE trending and S-verging reverse fault planes arranged in thrust systems and affecting the Quaternary succession (Poli et al., 2014). The proposed methodology included deep and shallow geoelectrical and GPR techniques to upscale the buried geological structures and to identify the site for the excavation of paleoseismological trenches. The adopted multiscale geophysical approach was applied in the studied area perpendicularly to the morphotectonic evidence of the Budoia-Aviano fault. The first step of the multiscale approach defined a Deep Electrical Resistivity Tomography (DERT). The DERT was long around 6000m, and it was able to obtain an investigation depth of about 1000m. The used DERT apparatus is a multichannel system designed and implemented by the CNR-IMAA (Rizzo et al.2004; Rizzo and Giampaolo, 2019). The acquired DERT data set was processed and elaborated through a procedure built ad hoc for this type of geoelectric surveys. While the first step highlighted the deep geological structure, several shallow high resolution geophysical surveys were planned close the morphotectonic evidence along the Budoia-Aviano thrust fault. Several shallow Electrical Resistivity Tomographies (ERT) with different electrode spacing were carried out. Three ERTs were carried out with an electrode spacing of about 5m obtaining an investigation depth of about 60m. Consequently, in order to increase the shallow resolution, a high resolution ERT with an electrode spacing of about 1m was acquired. The results of the shallow ERTs highlighted the buried geological structures in terms of subsurface faults and geological formations. Moreover, taking in account the previous results, several GPR profiles were carried out on the investigated area and the obtained results permitted to identify the site for the excavation of two paleoseismological trenches (Poli et al., at this session 1.1). The GPR results well depicted the highresolution image of the buried geological deformation, that were highlighted during the excavation phase (Poli et al., 2024). Finally, the multiscale geophysical approach allowed to improve the interpretation of previous geological and morphotectonic studies of the investigated area
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
