No full textStenopsoides newi Semeraro sp. nov. (Figs 1A,E,I, 3A–E, 6) Description. Body length ♀ 6.5–7.4 mm (n=3). General colour yellow, unicolorous. Face generally yellow except for reddish brown fine pitting particularly around vertex, anteclypeus and lorum orange or vermilion. Pronotal tubular extension yellow with brown coarse pitting amalgamated dorsomedially so tubular projection may appear to have a diffuse brownish stripe dorsally; calli smooth yellow (distinct), mesonotum and scutellum smooth, yellow. Tegmen mostly transparent with a hint of yellow; base of tegmen along costal margin vermillion; veins yellow. Fore and midfemur mostly orange or brown and hindfemur brown at apex, basal 1/4 of tibia brown. Head. (Figs 1A,E, 3A,C,D) Distance between coronal pits slightly greater than inter-ocellar distance; distance between ocelli around 1.8–1.9 times distance of ocellus to eye (or subequal to slightly closer to midline of face than to eye); frontoclypeus either slightly wider than or equal/ subequal to length, width around 0.5–0.7 times width of face between eyes; lorum either equal in width to length or slightly narrower than long; maxillary plate narrowly visible posterior to lorum; anteclypeus strongly flexed mesad, slightly constricted preapically and expanded at apex, apical margin truncate but slightly sinuate medially. Thorax. (Figs 1A,I, 3A,B,C) Pronotal extension conical and directed dorso-anteriad, tapered gradually towards apex and rounded; pronotum rugose with some brown pitting, striae not distinctly visible; raised median ridge along apical 1/8 of pronotum dorsally and full-length ventrally. Mesonotum + scutellum without distinct pitting or if present only very fine and concolorous; width across base 1.2–1.3 times mesonotum + scutellum length. Tegmen length 3.2 times its width. Legs metafemur with apical setal formula 2+1+1 or 2+1+0 with preapical setae fine; metatibia with 7–8 macrosetae on anterodorsal margin; 3–4 fine setae on anterior face of metatibia. Abdomen. (Fig. 3E) Female seventh sternite (7S) shape as in generic description, width around 2.7 times maximum height. Ovipositor apex not protruding, level with apex of pygofer in ventral view (n=1). Etymology. This species is named as tribute to Emeritus Professor Tim New who was Linda Semeraro's principal supervisor on her thesis project on macropsine leafhoppers. Type material.

Distribution. Western Australia (Fig. 6). Host. Unknown. Differential diagnosis. Stenopsoides newi Semeraro sp. nov. may be recognised from other species in this genus by a combination of characters. It has a larger body size than either S. punctatus Semeraro sp. nov. and S. truncatus Semeraro sp. nov. but overlaps in size with S. turneri. It is mostly yellow with some orange on the face, legs and base of tegmen; the scutellum is bright yellow, contrasting with the pronotum and tegmen. The extended pronotum bears a single diffuse brown stripe dorsally, (S. turneri has lateral stripes on either side of the pronotal extension and S. punctatus Semeraro sp. nov. and S. truncatus Semeraro sp. nov., have no brown stripes). Similar to S. punctatus Semeraro sp. nov., the extended pronotum in lateral view is directed dorsoanteriad and is conical, tapering to a rounded apex (differs to S. turneri which is slightly flattened and broadened at apex and from S. truncatus Semeraro sp. nov. which is truncate at apex when viewed dorsally). There is some brown banding on apex of hind femur and base of hind tibia which is contrasted against the rest of the yellow leg (other species have entirely yellow legs, or only some orange markings). The coronal pits are slightly further apart than the inter-ocellar distance (in other species they are about the same distance from each other). Similar to S. truncatus Semeraro sp. nov., there are no brown spots on the tegmen (S. punctatus Semeraro sp. nov. has spots evenly over the tegmen and S. turneri has spots in costal cell only).Published as part of Semeraro, Linda, Fletcher, Murray J., Malipatil, Mallik B., Constant, Jerome & New, Timothy R., 2021, Revision of a unique Australian leafhopper genus Stenopsoides Evans (Hemiptera: Cicadellidae: Idiocerinae: Macropsini), pp. 117-131 in Zootaxa 4999 (2) on pages 122-124, DOI: 10.11646/zootaxa.4999.2.2, http://zenodo.org/record/508941

Anti-TNF therapy for juvenile idiopathic arthritis-related uveitis
No full textFrancesco Semeraro,1 Barbara Arcidiacono,2 Giuseppe Nascimbeni,1 Martina Angi,1 Barbara Parolini,2 Ciro Costagliola31Eye Clinic, Department of Neurological Sciences and Vision, University of Brescia, Brescia, Italy; 2Department of Ophthalmology, S. Anna Hospital, Brescia, Italy; 3Eye Clinic, Department of Health Sciences, University of Molise, Campobasso, ItalyAbstract: Juvenile idiopathic arthritis-related uveitis is the most common type of uveitis in childhood and one of the main causes of visual impairment in children. The introduction of biological treatment has widened the range of therapeutic options for children with uveitis refractory to standard nonbiologic immunosuppressants. Data from clinical trials suggest that both adalimumab and infliximab have demonstrated effectiveness and safety in open-label studies, although no large, randomized, controlled trials have been reported so far. The role of etanercept in treating juvenile idiopathic arthritis-related uveitis is not yet well defined. In our experience, anti-tumor necrosis factor therapy has been shown to be more effective than steroids and/or methotrexate in treating uveitis. Up to now, tumor necrosis factor blocking compounds have been reserved for the treatment of the most severe cases of refractory uveitis, and larger prospective clinical trials are required in order to better assess the safety of these new compounds.Keywords: adalimumab, etanercept, inflixima
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

Gestione informatizzata dei dati archeologici e dei sistemi GIS. Applicazione al sito di Hierapolis di Frigia
No full textThe system used for organizing the data from the excavation at Hierapolis, a sample site for this research project, represents an example of the application of the methodology of GIS to a stratigraphically excavated site. The use of this methodology, based on the logical structuring of data in independent layers, makes it possible to reconstruct the micro-dynamics typical of a stratigraphic excavation. Once the archaeological layers are separated, divided and organized according to their geographic position, they are treated as a series of divisible and superimposable layers which can be used in order to create the floor plans of single monuments and, more in general, maps showing the different phases of the city. This type of data management makes it easier to understand the spatial organization and transformation of a city over time
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Modelling of back tempering in laser hardening
No full textBack tempering is one of the most critical problems in laser hardening of extended surfaces. In this type of treatment, several laser tracks are slightly overlapped to obtain a uniform hardened surface. Due to the overlapping, tempered zones are generated on the treated surface with the consequent lack of uniformity in the surface hardness. In this work, a regression model was developed to estimate the loss of hardness due to the tempering effect as a function of the thermal cycle. A specific test, named laser surface treatment test, was designed and executed to reproduce the hardness reduction due to the tempering effect. An analytical thermal model was developed to evaluate the thermal cycle undergone by the material during this test. By the results of the laser surface treatment test combined with the analytical model, a prediction model was estimated. Good agreement was found between predicted and measured hardness decrease, and the identified model could be integrated in a numerical code to evaluate the optimal process parameters
