"Per una politica delle città"
No full textIl volume esamina, attraverso una serie di contributi disciplinari diversi - di geografi, urbanisti, architetti, storici, sociologi, politologi - le trasformazioni del processo di urbanizzazione in Italia e in Europa e i fattori che incidono sulle nuove forme di urbanità.
Il contributo di C. Sebastiani in particolare esamina i fattori politici e istituzionali che oggi influenzano i processi di sviluppo delle città italiane a partire dalle riforme del governo locale e nel contesto di una marcata europeizzazione delle politiche urbane. E' volto altresì a dimostrare l'urgente necessità di un dialogo tra le discipline urbanistiche e l'analisi delle politiche pubblich
Pia Sebastiani, piano (Argentina)
No full textConcierto interpretado por Pia Sebastiani. Esta pianista y compositora nació en Buenos Aires, donde estudió con la orientación de los maestros Lalewicz, Gilardi y Baldi. Merced a los numerosos premios y becas nacionales y extranjeros obtenidos en el comienzo de su carrera, viajó más tarde a Europa y los Estados Unidos, donde se perfeccionó con los maestros Marquerite Long, Magda Tagliaferro, Olivier Messiaen, Darius Milhaud y Aaron Copland. Así, esta artista egresó del Conservatorio Nacional de París y del "Berhshire Music Center" (Tanglewood). Desde entonces realizó ininterrumpidamente giras por los más importantes centros musicales de Europa, Latinoamérica y los Estados Unidos.
En este concierto interpretó obras de D. Scarlatti, J. Brahms, C. Debussy, G. Faure y A. Ginastera

Cognitive technologies as boundary objects in digital place
No full textBoundary objects consist of devices, artifacts, and images that support the construction of meaning by different actors (Carlile, 2002, 2004). By acting and interacting, people even transform subjective meanings into artifacts, assigning meaning to reality, and thereby constructing it. Boundary objects translate, coordinate, and align the perspectives of different parties (Klimbe et al., 2010), but with their plasticity, they remain both adaptable to local needs and robust enough to maintain a common identity across different uses (Mele, Sebastiani and Corsaro, 2018). This paper explores the role of cognitive technologies as boundary objects in digital space. An interactive, qualitative, case-study approach is adopted to gain insights into the phenomena described. Starting from the idea that social construction and sensemaking process that transform spaces and create a “sense of place” (Parsons et al., 2017: 143), we show the way cognitive technologies perform inmost cases as boundary objects enacting actors’ interactions and sensemaking in digital space
Corsaro D., Sebastiani R., Mele C. (2016) “Practices of Service Innovation Diffusion”, in “Innovation in Practices” di Tiziana Russo-Spena, Cristina Mele e Maaria Nuutinen, Springer.
No full textService innovation has been often conceptualized as a linear multi-stage development process within a main innovator system. In this logic, innovation is communicated through certain channels over time and adopters play a key role in the process of innovation diffusion. This study moves away from this conceptualization and proposes service innovation diffusion as an emergent process of co-construction and sense-making by companies, customers and other partners. Such actors enact practices by interacting and integrating resources in a social, economic and cultural context. In particular, thanks to the analysis of 10 case studies we identify specific practices of service innovation diffusion in which actors make sense and share meanings about the newness, both individually and collec-tively. They are enabling confidence on service innovation, creating shared meanings among actors, and leveraging on actors’ competen-cies. The study also shows the dual role of users which can act both, and simultaneously, as adopters and rejectors
Cryoglobulins and Cryoglobulins Secondary to Hepatitis C Virus Infection
No full textThe term cryoglobulinemia refers to the presence in the serum of one (monoclonal cryoimmunoglobulinemia) or more immunoglobulins (mixed cryoglobulinemia, MC), which precipitate at temperatures below 37 °C and redissolve on rewarming; this is an in vitro phenomenon. © 2014 Elsevier B.V.

Hydroxychloroquine for treatment of rheumatoid arthritis: multifocal electroretinogram and laser flare-cell photometry study
No full textStefano Sebastiani, Michela Fresina, Mauro Cellini, Emilio C Campos Department of Experimental, Diagnostic, and Specialty Medicine, Ophthalmology Service, University of Bologna, Bologna, Italy Purpose: To evaluate early changes in multifocal electroretinogram (mfERG) and subclinical aqueous humor flare and cellularity in patients receiving hydroxychloroquine (HCQ) as treatment for rheumatoid arthritis.Methods: Ten patients receiving treatment with HCQ and no ophthalmic symptoms were enrolled. After complete ocular examination, mfERG and laser flare-cell photometry were performed. Patients were also divided into two subgroups with HCQ cumulative dose (CD) higher or lower than 500 g. Results obtained were compared with a control group of ten healthy subjects and statistical analysis was performed.Results: In patients receiving HCQ treatment, mfERG P1-wave in ring 2 showed a significant reduction in amplitude and a significant increase in latency compared to healthy control subjects, respectively resulting in 1.143 µV vs 1.316 µV (P=0.040) and 38.611 ms vs 36.334 ms (P=0.024). These changes are highly related to CD. Furthermore, when using the laser flare-cell photometry, a significant increase in aqueous humor flare and cellularity was shown in patients with CD higher than 500 g, resulting in a mean value of 14.4 ph/ms compared to 8.1 ph/ms in patients with CD lower than 500 g (P=0.0029). These reports appear highly related to CD (P=0.001). Receiver operating characteristic curve analysis showed mfERG P1-wave amplitude in ring 2 as the most sensitive value in detecting early HCQ-related retinopathy.Conclusion: MfERG was shown to be a very sensitive test in detecting early retinal toxicity and should be used for the screening of patients receiving HCQ treatment. Although less sensitive, laser flare-cell photometry can provide further information to evaluate early toxic retinal cell damage. Keywords: hydroxychloroquine, multifocal electroretinography, laser flare-cell photometry, rheumatoid arthriti
I primi lettori di Urania e la lingua dell’hybris di Arthur Clarke
No full textAnalisi linguistica e stilistica delle edizioni italiane di "Le sabbie di Marte" di Arthur C. Clarke, in particolare della prima edizione Urania (1952), con cui si apre la celebre collana di fantascienza italiana. Oggetto della ricerca è individuare le caratteristiche della lingua (e in particolare del lessico) tradotta dall'inglese con cui si sono confrontati i primi lettori di Urania, il che ha consentito retrodatazioni di parole quali "astronave" e "intercomunicazione"
