    This paper reconstructs the history of the journal Sociology of Communica-tion and the development of Communication Studies in Urbino through a dialogue with sociologist Lella Mazzoli, who served as editor-in-chief during the formative years of Communication Sciences in Italy. It traces the journal’s origins, the key figures involved, and the broader context that shaped its creation two decades be-fore the establishment of Communication Studies programs in the country. By ex-ploring the intricate connections between the journal’s trajectory and the evolution of Communication Studies, the analysis highlights its foundational positioning within the sociology of communication and culture, offering insights into its role in shaping the multidisciplinary field

    Purpose - The purpose of this paper is to investigate a method for comparing the scanning and reproducing accuracy of highly shaped objects like plaster casts used in dentistry. Design/methodology/approach - Theoretical considerations on errors introduced by the scanning systems and subsequent point clouds data elaboration have led to a method to estimate the accuracy of the whole process. Suitable indices have been chosen and computed at each stage. As a final result, the overall chain, scanning and reproducing systems can be assessed. In order to validate the proposed method casts have been scanned by means of commercial systems and then reproduced by using different rapid prototyping technologies, materials and parameters. Error indices have been computed and reported. Findings - Since it is not possible to define reliable and meaningful reference models for non-standard shapes, an absolute accuracy value for the scanning process cannot be stated. Anyway the proposed method, thanks to relative performance indices, allows the comparison of different acquisition systems and the evaluation of the most performing manufacturing chain. Practical implications - The study provides a method to assess the relative performance between commercial systems both in scanning and reproducing stage. Originality/value - In literature, some studies on the accuracy of scanning devices have been found but they are based on standard geometrical features. In this paper, the problem of complex shapes in absence of reference model is addressed instead

    Progettazione di Placche Craniche Personalizzate usando Tecnologie SFF e Sistemi di Modellazione Haptic

    Repairing severe human skull injuries requires customized cranial implants. Trauma and cranial tumors are the main causes for large cranial defects. The success of the reconstructive cranial surgery depends on diverse aspects regarding the preoperative evaluation of the defect, the design and manufacturing of the implant and the execution of the operation. Currently, the design of membranes is mainly a manual work, even with the use of CAD facilities, and results in a time-consuming and user-dependent skull reconstruction. This paper presents a critical review of a design methodology for custom-made cranioplasty plates in a PHANToM®-based haptic environment and the possibility to manufacture the same using Solid Freeform Fabrication technologies

    Iltirocinio sonoro - Gres: un'espereinza formativa condivisa tra studenti ed educatori di nido d'infanzia

    Dal settembre 2004, un accordo tra il Settore Istruzione del Comune di Bologna e la Facoltà di Scienze della Formazione dell’Università ha dato vita a un gruppo di lavoro che intendeva sperimentare un nuovo modello di formazione congiunta per educatori di nido: il GRES, Gruppo di Ricerca sull'Educazione al SOnoro. L’accordo prevedeva infatti l'attivazione di un gruppo di studio e formazione eterogeneo, composto da esperti di educazione musicale, educatrici di nido e studentesse universitarie, coordinato da Anna Rita Addessi, docente di Educazione al sonoro nel Corso di Laurea in Educatori di Nido e di Comunità Infantile e da Franca Mazzoli, docente e consulente per la formazione dei nidi per il Comune di Bologna. L'articolo illustra i presupposti teorici di tale collaborazione, le attività svolte e i risultati ottenuti

    Evaluation of the erosion rate in the Southern Apennines (Italy) based on geological-geomorphological data / Valutazione del tasso di erosione in Appennino Meridionale da dati geologico-geomorfologici

    The object of this study is the estimation of the long-term erosion rate in the southern portion of the Apennines chain (southern Italy). This was done with the aim of validating the hypothesis, proposed by MAZZOLI et al.. (2008), that thin-skinned extensional tectonics played a major role in the exhumation of formerly deeply buried tectonic units. More in detail, the study aimed at providing data on the erosional component of the rock exhumation which, based on Apatite Fission Tracks data reported in MAZZOLI et al. (2008), has affec- ted in the last 10 Ma the deepest units in the southern Apennines fold–and-thrust belt. The erosion rate was estimated based on the evaluation of the volume of deposits delivered by a large hydrographic basin to a conti- nental environment sedimentary basin. The accumulation basin is the Sant’Arcangelo basin (hereinafter BSA), which developed as a marine environment wedge-top basin (originally connected to the Apennines foreland basin) during the Middle Pliocene and evolved as an alluvial-lacustrine basin in the late part of the Early Pleistocene in response to the thrusting related uplift of a ridge located to the E of it (VEZZANI, 1966, 1967; CARBONE, 1991; PIERI, 1994; ZAVALA, 2000; PATACCA & SCANDONE, 2001; GIANNANDREA & LOIACONO, 2003; BENVENUTI et al., 2006). The drainage basin correlated to the BSA covers a large portion of the eastern slope of the Southern Apennines, and includes elevations formed of formerly deep-seated structural units (namely, Lagonegro units and Apulian platform unit) exhumed during Pliocene-Quaternary times. Literature data and field surveys allowed the identification of the sedimentary unit (Castronuovo-San Lorenzo unit, CSL, composed of lacustrine deposits passing laterally and upwards into alluvial plain sediments) which was deposited within the BSA when the basin was isolated from the neighboring foreland basin. The CSL ranges in age from around 1 to 0,7 Ma (PATACCA & SCANDONE, 2001; MAT- TEI et al., 2004; SABATO et al., 2005). G.I.S. elaborations allowed the reconstruction of the top and bottom surfaces and volume of the CSL. The calculated volume value was corrected accounting for the erosion which affected the CSL top surface, for the original width of the deposition area, for the suspended load loss, and for the sediment porosity. The paleo-hydrographic basin coeval to the CSL was reconstructed based on geomorphological/geological evidences, which include the compositional analysis of pebbles of different units of the BSA succession. The obtained 0,25 ± 0,07 mm/a erosion rate value is comparable to the values, averaged over the last 0,7 Ma and spanning from 0,2 to 0.3 mm/a, estimated for the eastern chain margin-foreland basin area in both the southern and northern Apennines (AMATO et al., 2003; CYR & GRANGER, 2008). These values, which can be considered as representative of erosion which has affected the Apennines over the Quaternary, are much lower than the Pliocene-Quaternary rock exhumation of formerly buried units estimated by AFT data, and this points to the important contribution of the extensional tectonics in the exhumation processes in the Southern Apennines
