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
High-performance materials and technological solutions to improve the thermal performance of historic buildings
Full text linkThe aim of the paper is to outline the state-of-the-art in the field of historic buildings' energy retrofit through high-performance materials or innovative solutions. The research question is to understand if the latter can be positively applied to historic building in terms of compatibility and can contribute to create tailor-made solutions, avoiding or mitigating critical issues from the preservation point of view. This required the evaluation of many publications including papers, handbooks, booklets, and guidance as well as research reports. The literature review was then summarized in two research fields for each building element: retrofit solutions and high-performance materials and solutions applied to historic buildings. The technical properties of these highly efficient materials and their possible uses in heritage buildings are shown through the comparison and the data analysis of some case studies. Starting from a general reasoning on retrofit solutions and the interactions between the various building components within a whole building energy retrofit project, the paper assesses how high-performance materials are or are not widespread, which kind of data is available and what is still missing
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
The Impact of the Loop Electrosurgical Excisional Procedure for Cervical Intraepithelial Lesions on Female Sexual Function
No full textIntroduction. Very limited knowledge exists concerning the impact of Loop Electrosurgical Excisional Procedure (LEEP) on female sexual function in women with cervical intraepithelial neoplasia Aim. To investigate sexual function in women who underwent LEEP for the treatment of cervical intraepithelial lesions, using a validated questionnaire (Female Sexual Function Index [FSFI]). Main Outcome Measures. FSFI questionnaire on six domains of female sexuality (desire, arousal, lubrication, orgasm, satisfaction, and pain). Methods. Consecutive sexually active women, who underwent LEEP for the treatment of cervical intraepithelial neoplasia were enrolled in this study. All women were asked to complete a copy of FSFI questionnaire, at the time of LEEP and after 6 months. We finally compared the results of the pre-LEEP questionnaire and the post-LEEP questionnaire for each patient. Results. A total of 67 sexually active women undergoing LEEP for the treatment of cervical intraepithelial lesions were enrolled. Nine of these patients (13.4%) completed only the questionnaire regarding their sexual function before LEEP; thus we did not include them for final analysis. In our study population, data showed a sexual function overall unchanged after LEEP; only the variable "desire" (sexual interest) became significantly worse (P = 0.02). Conclusions. LEEP for the treatment of cervical intraepithelial lesions doesn't affect women's sexuality, when compared with sexual function before surgery. In our study, all FSFI sexual function domains but desire, did not show significant change after LEEP. Serati M, Salvatore S, Cattoni E, Zanirato M, Mauri S, Siesto G, Cromi A, Ghezzi F, and Bolis P.

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
Garibaldi condottiero
No full textGiuseppe Garibaldi viene studiato nella sua lunga carriera militare, e valutato come comandante di grandi unità e non semplicemente come un capo guerrigliero in grado di condurre solo una guerra per bande. Si dimostra il peso decisivo che questo fattore ebbe nel processo risorgimentale e di unificazione nazionale
