Preparation and characterization of screening methods for classification and quality control of olive oils
Full text linkIn questo lavoro di ricerca di Dottorato sono state sviluppate piattaforme sensoristiche, basate su elettrodi SPE modificati con nanomateriali, per permetterere una rapida, facile ed economica individuazione delle frodi legate alla produzione e al commercio dell'olio extravergine di oliva. Il risultato della ricerca è stata la creaziobne di due piattaforme in grado rispettivamente di catalogare oli extravergine di oliva a seconda della cultivar della pianta di origine e di quantificare il contenuto di antiossidanti polari in campioni incogniti di olii vegetali, permettendo di discriminare oli di oliva da oli di altri semi.In this PhD research work, sensor platforms have been developed, based on SPE electrodes modified with nanomaterials, to allow rapid, easy and economic identification of frauds linked to the production and trade of extra virgin olive oil.

Oltre la pedagogia della neurodiversità: verso una pedagogia delle differenze
No full textIl contributo va oltre una visione centrata sulla neurodiversità per arrivare a una più ampia pedagogia delle differenze. Nel testo viene proposta una cornice teorica unitaria fondata su tre assi epistemologici: (1) intersezionalità, per rendere visibili le oppressioni che si sovrappongono e ridefinire curricoli, valutazioni e dispositivi educativi; (2) ecologia, che sposta l’attenzione dal deficit individuale ai sistemi relazionali, istituzionali e culturali che modellano le opportunità di apprendimento; (3) logica plurale, che riconosce l’identità come processo situato e relazionale e trasforma la relazione educativa in spazio di negoziazione e co-costruzione di significato. La prospettiva proposta permette di connettere le principali pedagogie della diversità – interculturale, di genere, speciale, dell’arco di vita e della neurodiversità – in una “costellazione” coerente, capace di guidare la progettazione inclusiva. Sul piano operativo, il capitolo evidenzia la necessità di adottare l’Universal Design for Learning, il modello bio-psico-sociale dell’OMS, metodologie di ricerca integrate, formazione docente unitaria e politiche educative che riconoscano la complessità delle differenze come risorsa trasformativa per l’intero sistema educativo
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
The Italian Archaeological Expedition in the Erbil Plain, Kurdistan Region of Iraq : Preliminary Report on the 2016-2018 Excavations at Helawa
No full textThe article is a preliminary report on the excavations conducted at Helawa by the Italian Archaeological Expedition in the Erbil Plain (MAIPE), Kurdistan Region of Iraq, during the 2016-2018 seasons. The site was surveyed in 2013 and 2015, revealing consistent occupation dating to the Late Chalcolithic period and briefer re-occupation in the mid-2nd millennium BC. Helawa is one of the largest 5th millennium sites in the Erbil Plain, probably reaching an area of 10 ha, and was abandoned at the beginning of the 4th millennium BC (early LC 3). The excavations (Step Trench B, Operations B1 and D, sounding G) established the chronological sequence, bringing to light a 5 m thick sequence of superimposed buildings and structures dating from the Ubaid to the early LC 3 period, located on the terraced southern slope of the higher mound, Middle/Late Bronze dwellings equipped with fire installations and storage facilities in Operation D, built directly over the last LC occupation at the site and an Islamic and LC 2 occupation in Operation G
