La Martella e Spine Bianche a Matera. L’architettura di una protratta ricostruzione
No full textWhy the Matera case? Within a decade, between 1950 and 1960, one of the noblest experiences of post-war Italian architecture took place in Matera, which immediately gave rise to a wide range of historical-critical literature that revealed the key role and premise for a new commitment to the reconstruction and development of civic life. From its inception,this episode had infact transformed the very concept of “reconstruction”, seen as post-war repair, and by extension, a more integral commitment, delivering the physical form and substance of the landscape to the city and the territory in Italy’s economic and social development
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
Big atrial natiuretic peptide: investigation on specific hormone-binding protein
No full textWe reported previously that the incubation of radioiodinated 1-28 human ANP ([I-125]alpha-hANP) for 24 h at 4 degrees C in plasma resulted in a partial conversion to large molecular weight forms of ANP (big ANP) To clarify whether binding of hANP to plasmaproteins is involved, the specificity, sensitivity and saturability of the binding were checked. The results obtained at 4 degrees C do not support the existence of ANP-binding proteins in plasma since none of the predicted requisites was fulfilled. Moreover we checked for temperature dependence of possible specific binding by repeating the same experimental steps at physiological temperature. Although at 37 degrees C there was enhanced binding with respect to that obtained at 4 degrees C, the results further demonstrate that human plasma does not contain specific ANP-binding protein. In conclusion the present data indicate that big ANP is not protein-bound but is an aggregated form. The question remains as to itspossible physiopathological role in vivo
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
