Densità, qualità, energia. Il quartiere Casanova a Bolzano
No full textDensificare la città elevando gli standard di qualità
della vita e riducendo i consumi energetici, sarà la
sfida del prossimo futuro. Il consumo di territorio
è a livelli ormai insostenibili per la nostra società,
il disegno urbano mostra città sempre più diffuse
dai limiti incontrollati e voraci di nuovo territorio.
La densità può invece generare efficienza, qualità,
piacere. Lavorare con la densità, infatti, vuol dire
non consumare altro territorio, utilizzare al meglio le
risorse esistenti, pensare lo spazio che viviamo come
frammento di un insieme più grande
Tecniche di Visualizzazione a supporto dell'analisi dei dati in FAIRWIS
No full textIl lavoro descritto in questo articolo è relativo al progetto FAIRWIS (Trade FAIR Web-based Information Services) il cui scopo è quello di costruire un sistema che offra servizi innovativi on-line per supportare l’organizzazione e la gestione di fiere reali e virtuali. Il sistema che si sta sviluppando è per molti aspetti diverso dai vari siti Web disponibili attualmente per varie fiere; in particolare, i dati forniti da questi siti non sono organizzati in un modo integrato e omogeneo e vengono di solito presentati in uno stile rigido e non facilmente modificabile. Inoltre, questi siti generalmente utilizzano dati statici che sono difficili da aggiornare e da mostrare in un formato appropriato. FAIRWIS è connesso a un database per garantire la coerenza dei dati e il continuo aggiornamento. Questo articolo descrive uno specifico modulo di FAIRWIS che utilizza tecniche di visualizzazione di dati allo scopo di agevolare l’interazione utente-calcolatore, permettere un facile accesso ai dati memorizzati e mostrare in un modo appropriato le informazioni ritrovate, in modo da supportare l’utente nell’analisi di tali informazioni
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
La ricostruzione del probabile aspetto fisionomico attraverso rilievi teleradiografici: determinazione del profilo
No full textVariations 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
Aetiology of influenza-like illnesses in the pre-COVID-19 season 2019-2020: role of coronaviruses: Irene Amoruso
Full text linkBACKGROUND: Only a proportion of seasonal influenza-like illnesses (ILIs) can de facto be attributed to influenza viruses. This study investigated the aetiology of ILIs to estimate the prevalence of human coronaviruses (CoVs) and to analyse their clinical-epidemiological traits. METHODS: A sample of 613 outpatients (253 adults, 360 children) with ILI in Veneto Region, Italy, was included. ILI was defined according with the EU Decision 2018/945. Sigma-Virocult nasopharyngeal swab were used. Nucleic acids were extracted with the QiaAmp Viral RNA Mini Kit (Qiagen). Molecular detection of respiratory viruses was performed with commercial One-step RT qPCR reagents (Allplex® Respiratory Panels, Seegene). Information on age, sex, symptoms, co-infections and comorbidities was collected. RESULTS: CoVs were the 3rd most frequent pathogen in adults (7.5%, after influenza and rhinovirus) and the 4th in children (4.7%, after influenza, rhino- and adenovirus). Subtype distribution was similar, with OC43 the most frequent. Probability of CoV involvement was twice in males (AOR=2.16; 95%CI: 1.05-4.39), whereas no association with age was noted. Co-infection with other viruses was frequent in children (65% of cases). CoV symptoms were not peculiar, although respiratory tract involvement was less likely than influenza (AOR=0.13; 95%CI: 0.04-0.41). Among CoV outpatients, 36% had one or more chronic diseases, compared with 5.6% among influenza (p = 0.001). CONCLUSIONS: Even before the COVID-19 pandemic, CoVs had a substantial role in ILI aetiology: 1 case of CoV every 3 influenza infections in adults. The higher prevalence of comorbidities among CoV positives compared to influenza indirectly shows the benefits of flu vaccines in individuals at higher risk. Careful surveillance of the viruses responsible for ILI continues to be desirable, including, but not limited to, detecting a possible change in the aetiology of ILI after the administration of SARS-CoV-2 vaccines in the population. KEY MESSAGES: • Pre-pandemic virological surveillance of influenza-like illnesses (ILIs) reveals how seasonal coronaviruses were the third most frequent respiratory pathogen in adults. • Prevalence of comorbidities was significantly higher in patients with a coronavirus-related ILI compared to influenza, supporting the benefits of flu vaccination for high risk groups
A quantitative and non-invasive vibrational method to assess bone fracture healing: a clinical case study
No full textOrthopaedics needs a robust diagnostic tool that can help or even replace traditional radiography in bone healing assessment, thus reducing patient exposure to ionizing radiation. We used a vibrational method to assess the healing of a complex fracture treated with external fixation, exploiting a quantitative and non-invasive procedure. Callus stiffening was monitored from the time of surgery until the fixator was removed. Our approach overcomes previous limitations and involves a longer period of healing monitoring (about 9 months), very frequent tests (bi-weekly), and the analysis of a single test configuration. The healing process was monitored by analysing the percentage increments of the squared resonant frequencies (SFIs), related to the stiffness variation and the changes in the frequency response functions. The results were validated by X-rays images, and revealed that the most sensitive parameter to quantify the healing was the SFI of the first resonant frequency which increased by about 20% per month during the formation of the woven callus and up to about 50% at the end of healing completion. This study confirms the potential of the vibrational method as an alternative to radiography in fracture healing assessment
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
