Le competenze manageriali dei Dirigenti Scolastici italiani
No full textQuesto lavoro illustra i risultati di un’indagine sulle Capacità manageriali dei dirigenti scolastici (DS) italiani delle scuole secondarie superiori, confrontandoli con quelli di altri cinque paesi industrializzati (Canada, Gran Bretagna, Germania, Stati Uniti, Svezia). I dati sono stati raccolti attraverso dettagliate interviste sulle pratiche gestionali dei DS. I risultati indicano che le pratiche manageriali dei DS italiani sono sostanzialmente meno efficienti di quelle misurate negli altri paesi. La differenza non è attribuibile tanto ai maggiori vincoli istituzionali, che pur caratterizzano l’operato dei DS italiani, ma riflettono piuttosto una carenza intrinseca di competenze manageriali. Un ruolo importante sembra essere giocato dal processo di selezione dei DS, che non appare in grado imporre un livello minimo di capacità manageriali ai vincitori di concorso. Questi risultati implicano che qualunque riforma della scuola italiana non può prescindere dal miglioramento delle capacità manageriali dei DS, responsabili principali dell’implementazione delle politiche scolastiche
TOPICAL TESTOSTERONE IN THE TREATMENT OF VULVAR LICHEN-SCLEROSUS
No full textObjectives: Comparison between 2% testosterone propionate and petrolatum ointment in the treatment of vulvar lichen sclerosus in a randomized, double-blind, controlled clinical study. Methods: Fifty-eight consecutive patients with histologically confirmed vulvar lichen sclerosus were enrolled. They underwent a 1-year period of topical treatment with either medication, with clinical evaluations of symptoms and gross appearance at 2-month intervals, followed by histological evaluation at the end of the treatment period. Statistical analysis was performed according to the chi-squared test and the Student-Newman-Keuls test. Results: A substantial improvement in symptoms was achieved in 20 (66.6%) patients in the testosterone group and in 21 (75%) patients in the placebo group. No statistical differences were observed between the two groups. Gross changes were observed in a few cases and no case demonstrated histologic modifications. Conclusions: Petrolatum ointment is as effective as 2% testosterone in the treatment of vulvar lichen sclerosus

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
