No full textSpaces of transformation at the limits of a city: the case of Volterra
No full textA Volterra si associa la definizione di gioiello di arte etrusca, romana, rinascimentale, per la valenza storico artistica tramandata negli anni. Al patrimonio caratterizzante il piccolo centro storico, che attrae turisti a livello internazionale, si unisce un valore aggiunto dato dall’imponente segno della vegetazione e dal paesaggio che si apre, dominandolo, su tutta la Valle del Cecina.
La conoscenza del luogo è limitata all’interno delle mura, non guarda al suo esterno, al contatto con la natura e con le zone urbanizzate in epoche successive, che presentano altrettanti segni storici di ugual valore.
Le criticità ambientali rendono Volterra un luogo difficilmente accessibile e non facilitano la conoscenza del territorio circostante le mura. Se nelle grandi città il limite urbano è caratterizzato da edifici anonimi, spesso con quartieri dormitorio, o zone industriali, o zone degradate, in Volterra il limite sembra quasi essere delimitato da un confine labile immaginario delineato dalle mura.
Lo studio ha evidenziato come anche la Volterra oltre le mura richieda il necessario riconoscimento dei valori storico artistici e della cultura. Ma per far questo è indubbiamente necessario pensare ad una nuova idea della città, con un’ottica di una innovazione che valorizza la tradizione, senza deturpare.
Nella relazione del quadro conoscitivo del piano strutturale di Volterra si individuano valenze e criticità della cittadina, elaborate nel processo di governo del territorio, con indagini scrupolose che hanno visto coinvolti cittadini e turisti ad esprimere opinioni.Tra le principali criticità affini alla scelta della valorizzazione del limite urbano:
a) scarsi spazi-percorsi naturalistici dedicati ad attività ricreative-sportive e didattiche; da ciò la necessità di prevedere percorrenze oltre il limite urbano, verso il territorio aperto, attraversando luoghi di interesse architettonico, naturalistico e storico
b) ridefinire il ruolo delle mura urbane non più viste come un limite urbano ma un continuum tra gli spazi verdi e costruiti esterni ed interni al centro storico;
c) creazione di luoghi verdi utilizzabili da fruitori esterni ma legati agli spazi costruiti caratterizzanti il volterrano – architettonici, archeologici, della salute, con possibilità di passeggiate archeologiche e privilegiando il recupero dell’esistente.
d) miglioramento della viabilità, con salvaguardia e ripristino di testimonianze storiche quali la vecchia rete ferroviaria che conduceva a Cecina, connettendo il paesaggio collinare al mare. Il territorio Volterrano, caratterizzato da una fitta rete di collegamenti minori che si diramano verso strategici punti della Toscana, manca di una principale arteria di grande scorrimento che permetterebbe una maggior fruibilità della cittadina dal settore turistico.
Posta come finalità del workshop un’azione di valorizzazione delle aree limitrofe urbane, al di là dalle mura, le aree individuate per promuoverne una effettiva valorizzazione e sostenibilità economica sociale ed ambientale, sono state la Badia Camaldolese, San Girolamo, San Giusto, Poggio alle Croci. Ulteriore tema è quello dell’ideazione di un nuovo sistema di mobilità - people mover per un sistema efficiente di connessione della città.
Le aree individuate, pur presentando una possibilità per lo sviluppo turistico ricettivo e per gli spazi dedicati ad attività ricreative dei cittadini stessi, risultano scarsamente note, con spazi degradati e criticità, che non rendono giustizia al valore storico artistico e naturalistico
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Rethink the political regime. A proposal of conceptual redefinition and application for the "democratic transition" in Argentina (1983-1989)
No full textEl artículo hace una propuesta de redefinición del concepto de "régimen político" a fin de ser aplicado al estudio de la "transición democrática" en Argentina. En primer lugar se muestra la necesidad de desambiguar el término a partir de una revisión de su uso habitual y su confusión con otros conceptos de la sociología política y la politología. Luego el artículo propone una reelaboración del término articulándolo con los conceptos gramscianos de "hegemonía", "relaciones de fuerza" y "revolución pasiva". Este desarrollo permite una fundamental reelaboración del análisis de la llamada transición democrática, entendida en esta propuesta como una forma específica de revolución pasiva, es decir un intento de reforma del régimen político enmarcado en un contexto de crisis mundial y localThis article makes a proposal to redefine the concept of "political regime" in order to apply it to the study of the "democratic transition" in Argentina. In the first place, we show the need to disambiguate this term, based on a review of its regular use and its confusion with other concepts of political sociology and political science. Then the article proposes a reworking of the term, articulating it with three Gramscian concepts: "hegemony", "relations of force" and "passive revolution". This development allows a fundamental reelaboration of the analysis of the so-called democratic transition, understood in this proposal as a specific form of passive revolution, that is, an attempt to reform the political regime framed in a context of global and local crisisFil: Massano, Juan Pedro.

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

Deferiprone
No full textDeferiprone (DFP) has been evaluated in a wide range of disorders, but most data come from transfusion-dependent thalassemia. The safety and tolerability profile includes gastrointestinal complaints, liver enzymes elevation, weight gain, arthropathy, neutropenia, and agranulocytosis. The last requires close monitoring of blood count and precludes the use of DFP in conditions with bone marrow abnormalities. The efficacy profile is similar among the three available chelators. For DFP, the choice of dosage is crucial to optimize the effect on liver iron concentration, according to the iron load degree and transfusional iron input. Growing evidence indicates that DFP, alone or in combination with deferoxamine, is effective in removing cardiac iron and preventing cardiac iron load. The available data consolidate an important role of DFP in the management of iron overload. There is a need to compare directly the relative value of the available chelators in the long-term prevention of iron toxicity by well-designed randomized controlled trials
