Area metropolitana e citta' diffusa: potenzialita' e limiti di un modello urbano
Full text linkRecenti proposte parlamentari porpongono di mettere fine ad una discussione sulla città e/o area metropolitana di Roma, confermandone:
• una dimensione d’area vasta coincidente con quella della provincia;
• la sussidiarietà e la sostenibilità come principi ispiratori ed ordinatori dell’azione di governo del territorio;
• le funzioni unitarie e complementari di livello territoriale (programmazione degli interventi per Roma Capitale, le opere di interesse statale, il patrimonio pubblico e privato nazionale ed internazionale, la valorizzazione e la gestione del sistema culturale, ambientale e del turismo, la ricerca e la formazione universitaria, le attività fieristico-congressuali-espositive, l’industria innovativa legata all’ICS);
collocando la questione della scelta metropolitana per Roma ad un livello europeo, eppure intermedio tra la scala politica propria della città-capitale e i compiti di programmazione e gestione che il nostro ordinamento costituzionale attribuisce alle province (per l’Europa, le NUT 3).
Rispetto a questo obiettivo, Roma non appare in posizione soddisfacente nella mappatura europea delle aree/città capitali metropolitane. Anche se, la spinta al policentrismo impressa dall’Unione potrebbe trovare già una base di corrispondenze nell’organizzazione – soprattutto spontanea - del territorio e dell’economia romana (non solo della Città).
Se per un verso, dunque, c’è da augurarsi che attraverso un più stretto recepimento delle indicazioni europee (Cfr. strutture già cooperative su base policentrica), l’area vasta romana, cioè la provincia, diventi nel prossimo periodo 2007-2013 molto più visibile; la mancanza di strumenti appropriati al raggiungimento di questo obiettivo rappresenta un freno alla piena realizzazione di una metropoli diversa dalla semplice somma di progetti ed impostazioni negoziati “dall’alto”, di portata nazionale e regionale, che escludono, ad una lettura “fisica e formale” del territorio, la domanda di integrazione “dal basso”, cioè il riconoscimento, anche economico, delle forme insediative coese riconoscibili romane.
In tal senso Roma e la sua provincia rappresentano il livello ideale per una lettura della programmazione territoriale europea, ma anche il livello sussidiario della mediazione tra una visione metropoitana globale e una locale, somma di insediamenti continui, diffusi o nucleari isolati (perirubanizzazione mista ad insediamento puntuale), attualmente privi di orientamento alla governance; lontani cioè da quell’insieme di regole con cui si attua la programmazione spaziale e fisica richiesta dall’Unione, entro cui ogni NUT offre il proprio contributo alla creazione di uno spazio integrato, anche attraverso scelte sussidiarie di metropolitanizzazione (cfr. Territorial Agenda 2007)
Intravenous Tranexamic Acid in Implant-Based Breast Reconstruction Safely Reduces Hematoma without Thromboembolic Events
No full textPatients’ Question-Asking About Breast Implant-Associated Anaplastic Large Cell Lymphoma (BI-ALCL) and Breast Implant Illness (BII): Implementing Questions in BREAST-Q
No full textAbstract: There has been recently heightened media-driven attention to BII and BI-ALCL. Nowadays the importance of receiving correct and complete evidence-based information about these diseases and the potential impact of these emerging issues on disposition to receive breast implants are not investigated on BREAST-Q. The BREAST-Q survey has the potential to create an evidence-based approach to aesthetic surgical practice. We suggest implementing the BREAST-Q subthemes domain in order to investigate the degree of satisfaction about the education received concerning BII and BI-ALCL and to investigate the possible change of patient perception towards breast implants.

The Evolution of Current Concept of the Reconstructive Ladder in Plastic Surgery: The Emerging Role of Translational Medicine
Full text linkPlastic surgeons have used the reconstructive ladder for many decades as a standard directory for complex trauma reconstruction with the goal of repairing body structures and restoring functionality. This consists of different surgical maneuvers, such as secondary intention and direct tissue closure, as well as more complex methods such as local tissue transfer and free flap. The reconstructive ladder represents widely known options achievable for tissue reconstruction and wound closure that puts at the bottom rung the simplest methods of reconstruction and strengthens the complexity by moving upward. Regenerative medicine and surgery constitute a quickly spreading area of translational research that can be employed by minimally invasive surgical strategies, with the aim of regenerating cells and tissues in vivo in order to reestablish normal function through the intrinsic potential of cells, in combination with biomaterials and appropriate biochemical stimuli. These translational procedures have the aim of creating an appropriate microenvironment capable of supporting the physiological cellular function to generate the desired cells or tissues and to generate parenchymal, stromal, and vascular components on demand, and above all to produce intelligent materials capable of determining the fate of cells. Smart technologies have been grown that give extra “rungs” on the classic reconstructive ladder to integrate a more holistic, patient-based approach with improved outcomes. This commentary presents the evolution of the traditional concept of the reconstructive ladder in the field of plastic surgery into a new course with the aim of achieving excellent results for soft tissue reconstruction by applying innovative technologies and biologically active molecules for a wide range of surgical diseases
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
Variations 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
Can the Elastic of Surgical Face Masks Stimulate Ear Protrusion in Children?
Full text linkIn this period of the Covid-19 pandemic, a protective mask has become a common object of use to contain virus transmission. The imminent need for masks has led many governments to produce them, including surgical masks with elastic loops or masks with side cuts at the ears. Among those on the market, surgical masks with elastic loops are the ones most chosen by parents for their children. These elastics cause constant compression on the skin and, consequently, on the cartilage of the auricle, leading to erythematous and painful lesions of the retroauricular skin when the masks are used for many hours a day. Pre-adolescent children have undeveloped auricular cartilage with less resistance to deformation; prolonged pressure from the elastic loops of the mask at the hollow or, even worse, at the anthelix level can influence the correct growth and angulation of the outer ear. In fact, unlike when using conservative methods for the treatment of protruding ears, this prolonged pressure can increase the cephaloauricular angle of the outer auricle. It is important for the authorities supplying the masks to be aware of this potential risk and for alternative solutions to be found while maintaining the possibility of legitimate prevention of the potential spread of the virus.

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
