Un capitalismo per tutti : la Montedison di Mario Schimberni
No full textL'ascesa e il declino della Montedison di Mario Schimberni. Enorme conglomerato di oltre 100.000 dipendenti da sempre al centro di brame politiche e finanziarie nazionali e internazionali, negli anni Ottanta l'impresa andò incontro a una pesantissima ristrutturazione che la riportò all'utile. Dopo uno storico accordo con l'ENI per la divisione fra chimica pubblica e privata, si svilupparono costruttive relazioni con i sindacati, si rilanciò la ricerca scientifica, si riprogettarono le attività industriali (Himont) e terziarie: supermercati, banca e finanza. Le quotazioni a Wall Street e le clamorose acquisizioni di Bi-Invest e la Fondiaria minacciarono di sconvolgere il panorama del capitalismo italiano, da sempre improntato alle logiche del «salotto buono» di Mediobanca. Fino alla scalala di Raul Gardini, che pose fine al sogno di Schimberni e del suo top management di fare della Montedison la prima public company italiana. Utilizzando ampia documentazione inedita (verbali del Consiglio di amministrazione e degli organi direttivi, lettere, testimonianze dirette dei tanti protagonisti aziendali dell'epoca e un memoriale segreto di Schimberni stesso, che in prima persona commenta - non senza colpi di scena - il suo rapporto con Enrico Cuccia), il volume ripropone all'attualità un progetto imprenditoriale di respiro mondiale
Complication and recurrence rate in laser CO2 versus traditional surgery in the treatment of Bartholin’s gland cyst
No full textPURPOSE:
The treatment of Bartholin's gland cysts by traditional surgery is characterized by some disadvantages and complications such as hemorrhage, postoperative dyspareunia, infections, necessity for a general anesthesia. Contrarily, CO2 laser surgery might be less invasive and more effective as it solves many problems of traditional surgery. The aim of our study is to describe CO2 laser technique evaluating its feasibility, complication rate and results vs traditional surgery.
METHODS:
Among patients treated for Bartholin's gland cyst, we enrolled 62 patients comparing traditional surgical excision vs CO2 laser surgery of whom 27 patients underwent traditional surgery, whereas 35 patients underwent CO2 laser surgery. Mean operative time, complication rate, recurrence rate and short- and long-term outcomes were assessed.
RESULTS:
The procedures required a mean operative time of 9 ± 5.3 min for CO2 laser surgery and 42.2 ± 13.8 for traditional surgery. Two patients (5.7 %) needed an hemostatic suture for intraoperative bleeding in the laser CO2 laser technique against 14.8 % for traditional surgery. Carbon dioxide allows a complete healing in a mean time of 22 days without scarring, hematomas or wound infections and a return to daily living in a mean time of 2 days. Instead, patients undergone traditional surgery required a mean time of 14 days to return to daily life with a healing mean time completed in 28 days.
CONCLUSIONS:
The minimum rate of intra- and post-operative complications, the ability to perform it under local anesthesia in an outpatient setting make CO2 laser surgery more cost-effective than traditional surgery
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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

No full textAppropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
