Valutazione dei costi nella chirurgia dell’ernia inguinale. Day surgery e one day surgery versus ricovero ordinario
No full textThe authors have completed an analytic research about costs of hospitalization and treatment for inguinal hernioplasty and costs of anesthesiologic and surgical techniques and hospitalization regimen. The authors consider possible in about 50% of cases the tension-free hernioplasty carried out with local anesthesia and day or one day surgery regimen and they have estimated that it is very less costly then traditional herniorraphy carried out with general anesthesia and hospitalization: L. 1.056.075 versus L. 2.252.650. In Emilia-Romagna we could have a considerable cost-saving, even if only the 50% of patients treated for uncomplicated inguinal hernia every year (7.133 patients with mean hospital stay = 5,8 days and total hospitalization = 41.731 days during 1993) could benefit by treatment in one day surgery regimen. In fact, leaving out of account the advantage of the rapid return the patient to work, the costs of hospital stay, esteemed in L. 25.038.600.000, would be L. 8.558.700.000. A considerable increase of one day surgery hernioplasties should be expected by the hospital administration in budget planning

Costi della colecistectomia dopo l’avvento della chirurgia video-laparoscopica
No full textThe authors proceeded to point out the hospital stay costs and the operating-room costs of the cholecystectomy after the introduction of the laparoscopic technique, underlining the higher economic advantages. The total unit cost for laparoscopic cholecystectomy, even if there are higher costs due to the surgical equipment, thanks to the mini-invasive approach and to the reduced hospital stay, results lower (17%) then the total unit cost for laparotomic cholecystectomy (L. 3.982.489 vs. L. 4.825.300). Let us suppose that in the Emilia Romagna Region an 80% of patients underwent to laparoscopic cholecystectomy and only a 20% underwent to laparotomic cholecystectomy: in this case there could be the economic savings of L. 3.777.478.902 and concerning the hospital stay there could be the savings of 17.928 days too. This cost estimation is important if we consider that the rate of cholecystectomy procedures, in our local area, per 1000 inhabitants, increased from 2.29 in 1990 to 3.99 in 1992 (rate of increase: 74%)

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
Appropriate 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
