A designed and tailored compost for different applications: innovative procedure applied to different compost property characterisation
No full textIn relation with specific application of compost, the utilization of dedicated compost can be considered using additives or enzyme for a tailored and a specific designed material. At the same way engineered system of laying biowaste or manure sanitation through the application of new biological technologies (bio-treatment) can be developed to obtain quality marketable fertilizer, that improves the soil structure, enhances its fertility and rehabilitates for predesertification. The specific properties have to be monitored by a quality control systems.
A specific and “ad hoc” applications on compost products characterization can be carried out by dedicated lab test and assessment methods. Main aim of the study was to investigate the possibility offered by new procedures, as Hyperspectral Imaging, to evaluate the compost quality in order to develop control strategies to be implemented at plant scale and to individuate its best utilization field
AN INNOVATIVE PROCEDURE TO CHARACTERIZE PROPERTIES FROM TAILORED COMPOSTS
No full textThe first objective in aerobic conversion and composting process is to recycle biowaste, food and agriculture products and animal breeding residue. Compost obtained from different organic waste sources (municipal solid waste, biomass, etc.) is increasingly used as a product suitable for agricultural purposes. It is possible to obtain a compost that can be used in different applications such as a marketable fertilizer, substrate and soil substitute for environmental restoration etc. Each of the compost properties can be used for specific application of stabilized organic material: designed compost for landfill cover, in biofilter preparation for land recovery or in specialized fertilizer for niche agricultural products (i.e. soilless agriculture). In relation with specific application of compost, the production of dedicated compost can be obtained using additives or enzyme for a tailored and a specific designed material. The specific properties have to be monitored by quality control systems. A specific and "ad hoc" applications on compost products characterization can be carried out by dedicated lab test and assessment methods. In this paper a characterization method of tailored compost (Compost PAV) is reported as methodological proposal for compost quality testing, using a hyperspectral imaging approach. This technique, which combines the advantage of spectroscopy and the classical imaging, could be particularly useful to assess compost maturity and to detect contaminants, in respect of a full quality control and certification of compost. Compost patterns showed similar behaviour, with higher reflectance level in correspondence with the increase of compost ageing
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
La sostenibilità come strategia di sviluppo degli Atenei: il caso dell'Università di Bologna
No full textLo sviluppo sostenibile rappresenta un traguardo fondamentale per il genere
umano, di prosperità ed equità intra e intergenerazionale che allarga l’orizzonte di
riferimento delle scelte e fornisce lungimiranza all’azione di governo di tutte le
istituzioni, incluse le università. In particolare, l’idea di sviluppo sostenibile sottesa
nell’Agenda 2030 delle Nazioni Unite rappresenta un piano d’azione per trasformare
il mondo, agendo a favore delle Persone, della Pace, del Pianeta, della Prosperità e
delle Partnership. Nelle istituzioni universitarie, ciò è realisticamente possibile
quanto più il valore, la forza comunicativa e ispiratrice dei Sustainable Development
Goals (SDGs) entra a far parte del quotidiano, incidendo concretamente sui
comportamenti di docenti, del personale amministrativo, degli organi di direzione e
controllo e, non ultimo per importanza, delle migliaia di studenti che animano la vita
degli atenei. L’Università di Bologna, con oltre 85 mila studenti, 5.853 dipendenti ‐ tra
personale accademico e tecnico amministrativo – più di un milione di metri quadrati
di patrimonio costruito, 1,7 milioni di risorse del patrimonio bibliotecario, un
budget annuale di circa 800 milioni di euro, un programma edilizio di 230 milioni di
euro nei prossimi 3 anni, ha un evidente impatto diretto e indiretto sull’economia
locale, sulla società e sull’ambiente circostante. Su tali basi l’Alma Mater ha fatto
propri i 17 Sustainable Development Goals delle Nazioni Unite (UN, 20151) quale
quadro di riferimento dell’azione di governo e strumento per misurare i progressi
compiuti verso una società sostenibile, operando nel rispetto delle risorse
disponibili e ponendo l’attenzione sulle esigenze delle future generazioni, motore e
al contempo ragion d’essere di un’istituzione universitaria.
L’articolo analizza anzitutto lo stato dell’arte nelle università italiane attraverso
le esperienze degli atenei che fanno parte della Rete delle Università per lo Sviluppo
Sostenibile (RUS), costituita in seno alla CRUI2 per indirizzare e condividere
strategie e pratiche in tema di sostenibilità. Nel successivo paragrafo viene
presentato il caso dell’Università di Bologna che fa parte della RUS e ne condivide gli
standard di misurazione e rendicontazione. All’interno della RUS, l’impegno verso la
società e l’ambiente dell’Università di Bologna ha assunto caratteri distintivi,
connotandosi per la pervasività degli obiettivi di sviluppo sostenibile sia dal punto
di vista degli strumenti di programmazione e controllo sia per la sua rilevanza
nell’indirizzare le decisioni istituzionali nella didattica, ricerca e terza missione.
L’articolo si chiude analizzando le “lezioni imparate” dal caso dell’Università di
Bologna e le implicazioni che ne discendono sul piano della governance istituzionale
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
