Gas Chromatographic/Mass Spectrometric Analysis of Azines
No full textWe have studied the gas chromatographic behaviour of several 3-methyl-2-benzothiazolone-azines. In HPLC analysis all the unsymmetrical azines show double peaks, whereas in HRGC analysis only some of these compounds show the two peaks corresponding to the Z (syn) and E (anti) isomers. By means GC/MS analysis the mass spectrum of each azine was recorded. We have assigned the E and Z configurations to the first and second gas chromtographic peaks on the basis of the ratio between the relative abundances of the two most significant framment ions at m/z 163 and 164

Il Social Impact Investing e le sue "ambiguità strategiche"; l'emergere, lo sviluppo e l'istituzionalizzazione di un nuovo "campo" sociale
No full textIl saggio introduce l'esperienza internazionale del Social Impact Investing, da un punto di vista sociologico, sottolineando l'ambiguità strategica del concetto, i motivi della sua crescente diffusione nel dibattito scientifico e l'istituzionalizzazione di quel tipo di finanza in diversi contesti nazionali, in particolare in Gran Bretagna e in Italia
Sociologia del SII: codice, programmi, accoppiamenti strutturali, organizzazioni e dispositivi sociotecnici
No full textIl saggio presenta tra i primi il campo del Social Impact Investment, dal punto di vista sociologica. Lo analizza attraverso alcuni approcci, quali quello della ibridazione, dell'allineamento di interessi, dell'accoppiamento strutturale e degli oggetti di confine, mostrandone limiti e potenzialità. Il "campo" viene poi analizzato attraverso la teoria dei sistemi sociali
Costruire e governare le partnership del SII. Una riflessione sui Social Outcome Contract
No full textIl saggio propone una riflessione sulla governance delle partnership che solitamente costituiscono il soggetto dei cosiddetti Social Outcome Contract. Ne risulta una messa a fuoco dei pericoli e dei paradossi che un loro governo gerarchico o mercantile potrebbe generare e una proposta per una governance multilivello, sperimentale e innovativa
APPLICATION OF NUMERICAL METHODS FOR THE STUDY OF THE 2014 CHALLENGES AND LESSONS LEARNED
No full textThe 2014 San Leo landslide is a very peculiar landslide, being controlled by a large number of factors that interacted with each other; each one was in turn critical in driving, promoting, or allowing the slope failure. In the ten years after the landslide event, numerous studies were presented in the form of national and international journal articles, conference proceedings, as well as unpublished technical reports. These projects allowed different aspects and mechanisms to be investigated, progressively enhancing our understanding of the landslide. In this paper, we summarize, review, and discuss the various numerical modelling analyses that have been conducted, in order to outline the foundations on which future investigations may be designed. Considering the in depth understanding that has been gained on the geological, lithological, environmental, and engineering aspects of this site, we suggest that the San Leo plateau may be an ideal engineering geological field laboratory useful in investigating the evolution and instability phenomena that affect sites with similar characteristics within the Marecchia Valley region and beyond
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
