Il supporto della Fondazione IFEL ai comuni in criticità finanziaria
No full textIl decreto legge n. 124 del 26 ottobre 2019, convertito, con modificazioni,
dalla legge 19 dicembre 2019, n. 157, ha previsto il finanziamento di interventi
della Fondazione IFEL in materia, tra le altre1, di prevenzione delle crisi finanziarie
(Linea 3).
Il 23 settembre 2020 IFEL ha, pertanto, sottoscritto con il Ministero dell’Economia
e delle Finanze (Dipartimento delle Finanze e Ragioneria Generale
dello Stato) e il Ministero dell’Interno (Direzione Centrale per la Finanza Locale
– Dipartimento per gli Affari interni e Territoriali) una convenzione per la
realizzazione degli interventi previsti
Proteolytic Fragmentation for Epitope Mapping
No full textThe use of antigen fragments generated by specific proteolytic cleavage is a relatively simple "library" approach for epitope mapping in which possible overlapping fragments are screened with the antibody on Western blots. Proteolytic fragmentation with numerous proteases having different cleavage specificites can be carried out on native and denaturated proteins, generating a small and large number of fragments, respectively. To determine the antigenic site of a monoclonal antibody, we have examined the limited proteolytic digestion of the transducin alpha-subunit with four different proteases and detected antibody binding to fragments by Western blot. Using this approach, the epitope for this antibody was localized within the amino-terminal 17 residues of transducin alpha-subunit
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
Allosteric inhibition of (125I) ET-1 binding to ET(A) receptors by aldoxime and hydroxamic acid derivatives
No full textEndothelin-1 (ET-1), a potent vasoconstrictor peptide, exerts its physiological effects by binding and activating specific G protein-coupled receptors, named ET(A) and ET(B). An unique property of ET-1 is its ability to bind almost irreversibly to its receptors. Aspirin and salicylic acid (SA) are allosteric inhibitors of ET-1 binding to ET(A) receptors. Dihalogenated derivatives of SA have been identified as more potent allosteric inhibitors than aspirin. In this study, disubstituted benzohydroxamic acid, benzaldoximes and dihalosalicylic acid dimers were synthesized and tested as inhibitors of [(125)I] ET-1 binding to ET(A) receptors in rat embryonic cardiomyocyte (H9c2 cell) membranes. Some dihalosalicylic acid dimers 2h showed good inhibitory activity, the most active compounds are the hydroxamic acids derived from anthranilic acid. Among these compounds, the 3,5-diiodo-2-aminobenzohydroxamic acid e compound 2a is three-folds more potent as inhibitor of [(125)I] ET-1 binding to ET(A) receptors than the 3; 5-diiodosalicylic acid reported in literature. Most aryl aldoximes in this study were biologically inactive as inhibitors of [(125)I] ET-1 binding to ET(A) receptors
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
