No full textMeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Facies and early dolomitization in Upper Albian shallow-water carbonates of the southern Apennines (Italy): paleotectonic and paleoclimatic implications
No full textThick successions of Cretaceous carbonates in the southern Apennines of Italy are of great economic interest since they host important aquifers and huge hydrocarbon accumulations. The reservoir of the Val d???Agri and Tempa Rossa oilfields (in the subsurface of Basilicata) consists of Upper Cretaceous rudist-rich lime- stones passing downward into mid-Cretaceous dolomitized limestones of restricted platform facies. Upper Albian- Lower Cenomanian dolomitized carbonates exposed in the Sorrento Peninsula and in the Cilento Promontory, part of the Apennine Carbonate Platform, represent a good surface analogue for the lower part of the reservoir. They are composed of meter-thick beds of stratabound dolomite and shallowing-upward cycles of restricted platform limestones capped by silicified evaporites and marly levels. Field relations, petrography, and geochemistry implicate the reflux of penesaline waters as the most probable dolomi- tization process. High-frequency climatic variability between dry and wet phases can explain the formation of evaporites, which are coeval with karstic bauxites in other sectors of the southern Apennines. The dolomitized car- bonates of the Sorrento Peninsula pass laterally into do- lomitized breccias, which were the result of local tectonic collapse of the platform. This is further evidence of mid- Cretaceous syn-sedimentary tectonics that in other areas of the Adria passive margin contributed to the formation of intraplatform basins where source rocks accumulated
Impact of the sars-cov2 pandemic on orthodontic therapies: An italian experience of teleorthodontics
No full textObjective: To assess the possibility of controlling patients at a distance according to principles of teleorthodontics to understand its possible usefulness in the future routine activity and the impact pandemic may have had on different types of orthodontic treatments. Material and Methods: One hundred orthodontic patients (57 F, 43 M, age 7-46) during quarantine were checked through videocalls and photos sent by patients following proper instructions. Three groups have been distinguished based on the type of therapy: A-fixed appliances; B-removable appliances; C-clear aligners. Relevant events about dental and gingival health, integrity of appliances, orthodontic therapies related symptoms and overall progress of treatments were recorded. Results: A and B groups reported higher percentages of gingival inflammation (27 and 22%), dental plaque (16 and 13%), deciduous tooth loss (8 and 16%). Bracket and attachment detachment were the most frequent events in A and C groups (22 and 23%). Pain and discomfort were reported in A and B groups (35 and 32%). Therapies continued to progress better in C (51% improved dental alignment) and B (31% improved malocclusions) groups. Conclusion: Orthodontics is safe and allows during emergencies to postpone checks. Everyday mobile-technology is useful in managing orthodontic patients unable to carry out in-person control. When their effectiveness equals other systems, treatments with clear aligners without attachments should be preferred in patients unavailable for regular checks
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
The role of MRI and CT in diagnosis and treatment planning of cherubism: a 13-year follow-up case report
No full textAim Cherubism is characterised by mesenchymal alterations during the development of the jaws secondary to perivascular fibrosis. According to the ALARA (As Low As Reasonably Achievable) principle, it is important to avoid conditions where the amount of radiation used is more than that needed for the procedure, because there is no benefit from unnecessary radiation. However, the use of MRI has been poorly studied in cherubism. Materials and methods The patient underwent head and neck MRI and 3D CT for imaging assessment. Results MRI is necessary to evaluate the extension of dysplastic tissue and the cystic part of the lesions. Bone window CT only allows evaluation of strong densitometric alterations of cherubism lesions. Moreover, on radiographic film it is not always possible to distinguish fibrous tissue from mucous pseudocystic tissue. By contrast these differences are readily evident on MRI. Conclusion MRI, in addition to other traditional radiographs and CT, could be useful in helping the clinician in the diagnosis and treatment of cherubism

Classification of Statistics learners using multi-dimensional latent class IRT model and archetypal analysis: The ALEAS app
No full textIn recent years the need for assistive technologies for teaching and assessing Statistics is steadily rising. The ALEAS app aims to provide an intelligent adaptive assessment proposing a learning analytics approach that combines a psychometric model (multidimensional IRT) with Archetypal analysis to estimate the learners' ability in comparison with their peers
Valutazione BIM-based ex ante dei rifiuti da C&D per la demolizione selettiva
No full textThe paper outlines a methodology for the preliminary assessment of construction and demolition (C&D) waste. In particular, the work focuses on the possibility of implementing selective demolition procedures, aimed at the punctual “deconstruction” of the building in order to streamline the materials and components reclamation operations, maximizing their reusability and/or recyclability potential. In this sense, the aim of the study is the elaboration of a BIM-based protocol for the pre-determination of material flows from demolition, through the standardization of the C&D waste production process. The protocol is in line with the Italian legislation and designed in the framework of the selective demolition site in compliance with the guiding criteria of the European legislation. The information derived from the application of the methodology fuels the knowledge system needed to frame the labelling of C&D products towards their possible reuse or recycling. Starting from the analysis of a case study, identified in the former Corradini industrial complex, located in the eastern area of Naples, the research experimentally developed the methodological articulation of the protocol, aiming at the quantification and management of waste flows, their pre-characterization according to
the CER code, and the planning of material flows towards reuse, recycling or landfill chains.
The research is the result of the PROSIT project - “Designing in Sustainability”, carried out by the Department of Architecture and the Department of Structures for Engineering and Architecture of the University of Naples “Federico II” with the public-private consortium STRESS scarl and in collaboration with the Municipality of Naples
