Tipologia, caratteri costruttivi e committenza dei castelli siciliani tra musulmani, Normanni e Svevi. Il caso di Segesta-Calatabarbaro nella Sicilia occidentale (secc. XII-XIII)

Sono presentati in forma molto sintetica i risultati, relativi al periodo medievale, di dieci anni di ricerche a Segesta (Trapani-Sicilia) e nel suo territorio. Le ricerche hanno previsto, oltre allò scavo stratigrafico in diverse zone del Monte Barbaro (Segesta), le ricognizioni sistematiche del territorio circostante, l'analisi delle stratigrafie murarie e delle tecniche costruttive. Questo modo di procedere ha consentito, a fronte di una presenza molto esigua di fonti scritte, di intendere le dinamiche del popolamento rurale tra VIII e XIII secolo, nonché le strutture del «potere» nell'ambito di due formazioni sociali profondamente diverse : quella islamica e quella normanno-sveva. Particolarmente illuminante è poi stato il confronto tra le strutture sommitali di Calathamet (a meno di dieci chilometri da Sege-sta) e quelle di Segesta/Calatabarbaro. In entrambi i siti è infatti leggibile il passaggio da un sistema «non compatto» e di scarso impegno costruttivo (fase islamica) al dongione, seppure in versione ridotta (fasi normanna e sveva), il passaggio quindi dalla dimora di un «capo» a quella di un «signore».Molinari Alessandra.

Design Thinking, Student Skills, and Educational Interventions
No full textOn September 10, 2019, Alessandra Molinari and Andrea Alessandro Gasparini have published an article entitled “When Students Design University: a Case Study of Creative Interdisciplinarity between Design Thinking and Humanities” in Open Education Studies. A Blog Post by Pablo Markin. In their article, Alessandra Molinari and Andrea Alessandro Gasparini have argued that “design thinking and the humanities share a common epistemological core that enables them, if applied in educational setting..
Sostanze Grasse Animali e Vegetali: Aspetti Qualitativi dei Prodotti Biologici
No full textThe aim of this study was to compare the effects of traditional and organic agricultural, feeding and breeding systems on the quality of lipids from animal and vegetable origin. The study was divided into three main sections: 1) evaluation of extra virgin olive oils obtained from olives produced by conventional and organic agricultural systems; 2) evaluation of liposoluble minor components obtained from soybeans and barley seeds produced by conventional and organic agricultural systems; 3) effects of different breeding and feeding systems on cholesterol oxidation and sterol content of freeze-dried egg yolks.
In general, slight, no significant differences were found between lipids from animal and vegetable products obtained by conventional and organic systems. Nevertheless, these results correspond to only one set of experiments, which could have been influenced by the particular weather conditions of the 2003 harvest. Therefore, this set of data should be considered as preliminary, but they represent a good starting basis for further studies in this field. More research is required in this area and it would be advisable to evaluate vegetable products from different harvest years, in order to draw valid conclusions
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
