Terrae incognitae dell’arte. Narrazioni e mappe della vita quotidiana nelle pratiche artistiche
No full textLa tesi esplora le modalità di dichiarare l'identità tra arte e vita attraverso diversi assi temporali e diversi movimenti: il movimento Dada tedesco e quello francese, l'Internazionale Situazionista e il GRAV, il Laboratorio di Comunicazione Militante, la videoarte in Europa e negli Stati Uniti come strumento di contestazione, la net.art e i movimenti contro la globalizzazione dentro e fuori il web, fino ad alcuni esempi di arte pubblica e esperimenti di cartografica critica. Viene esplorato un secolo di movimenti artistici e politici collettivi che, di volta in volta, utilizzano i mezzi tecnologici a loro più vicini per affermare con convinzione che l'arte non è "altra" dalla vita quotidiana ma, piuttosto, la riflette e può essere strumento per il suo miglioramento
La vegetazione acquatica e palustre dell’Italia nord-orientale. 1 – La classe Lemnetea Tüxen ex O. Bolòs et Masclans 1955.
No full textLa vegetazione acquatica e palustre dell’Italia nord-orientale. 2 – La Classe Potametea Klika in Klika et V. Novák 1941
No full textViene descritta la vegetazione acquatica rizofitica riferibile alla classe Potametea nell'Italia nord-orientale. Complessivamente vengono riconosciute diciotto associazioni e dieci aggruppamenti, afferenti a quattro alleanze (Ranunculion fluitantis, Potamion, Ranunculion aquatilis, Nymphaeion albae) nell'ambito di un unico ordine (Potametalia). Due associazioni sono descritte come nuove: Potametum prolixi e Sparganio-Vallisnerietum spiralis. Per ciascuna comunità vengono riportate informazioni su composizione floristica, sintassonomia, sinfisionomia, sinecologia e sincorologia. L'analisi ha anche evidenziato la progressiva contrazione o scomparsa in molti dei tipi di maggior pregio a seguito dei porcessi di modificazione ambientale e di eutrofizzazione delle acque
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

No full textValue Analysis and Knowledge Transfer in Multi-Project Management
No full textThe identification of critical knowledge and the ability to utilize and transfer it is a challenge for any multi-project organization. This paper aims to propose a structured model, grounded on the Value Analysis (VA) methodology, to support knowledge transfer and decision making in multi-project environment. Since most of studies on VA deal with single, independent projects, they miss to explain how the base of knowledge acquired and created during the execution of one VA project can be transferred and used in following projects. Instead, it is plausible to presume that certain knowledge on materials, working methods and design solutions the VA team acquired and created during one project can be transferred and re-used when designing another system.
The model this research proposes has been developed and validated through an action research, with researchers working in close contact with managers involved in developing the pipeline systems for a large cruise ship. Ship building products is the ideal field for multi-project management, because several VA projects need to be launched during each ship construction. The implementation of VA to improve several subsystems in a cruise ship led to the creation of a software application that facilitates knowledge transfer among VA projects, through the formalization of a shared knowledge database
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
