ICT in the data management. Analysis of the wooden roof of Santa Maria Assunta della Pieve (Novi Ligure)
No full textThe conspicuous number of data that you acquire and rework in the preservation process, sometimes risk being partly forgotten when the action ends, also because of the difficulties in reaching them (retrieval, filing, query and extraction of information, possibility of implementation during the various
stages of the work and by different operators). The paper wants to show a comparison between different processing technique of managing the data acquired analysing, through the case study of the wooden roof of Santa Maria Assunta dell Pieve (Novi Ligure); moreover we carried out the topographic survey, a diagnostic investigation about the condition of its trusses and their structural assessment.
After a first stage, common to all the analysed techniques, consisting of giving
back the topographic survey with software CAD, the same data, regarding
materials, decay and diagnostic results, have been manually edited in a database,
in GIS and BIM, paying special attention to the definition of the fields that characterize each element.
This exercise wants to support a consideration about the advisability of
employing the different techniques we analysed, particularly comparing their
advantages and disadvantages, time requirements, the degree of information
access and query chance, considering the theme of interoperability among the
systems we employed
Effetto del lisozima su ceppi diversi di Leuconostoc oenos: indagine preliminare
No full textLeuconostoc oenos is the main microorganism responsible for malolactic fermentation of wine; this is commonly controlled by means of sulphite. Trials were conducted to assess the possibility of use of lysozyme for control of L. oenos in wine. 3 strains of L. oenos (L230, L239 and L294) were exposed to lysozyme concn. up to 100 mug/ml, and growth was evaluated. The results showed considerable differences in lysozyme resistance; strain L230 showed high resistance, whereas strain L294 was inhibited by relatively low lysozyme concn. (10-25 mug/ml). Strain L239 showed intermediate resistance. The feasibility of use of lysozyme for control of malolactic fermentation of wines therefore depends on the lysozyme resistance of the L. oenos strains in individual wineries

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
