A survey on the cutting and packing problems
No full textThis paper presents a unified approach, based on a geometrical method (see Faina in Eur J Oper Res 114:542–556, 1999; Eur J Oper Res 126:340–354, 2000), which reduces the general two and three dimensional cutting and packing type problems to a finite enumeration scheme

No full textGli autori presentano un’indagine circa la morbidità-mortalità post-operatoria effettuata su 40 pazienti ultranovantenni operati in anestesia generale per frattura dell’estremo prossimale del femore. I pazienti, otto maschi e 32 femmine, ricoverati presso la Clinica Ortopedica dell?università di Genova nel periodo compreso tra il 1982 e il 1989, appartenevano per le condizioni fisiche alla classe ASA II in 4 casi e alle classi III e IV in tutti gli altri.
Per ciascuno di essi sono stati presi in considerazione:patologia pre-esistente alla frattura, tipo e durata dell’intervento, agente anestetico impiegato, complicazioni intraoperatorie e decorso postoperatorio. La patologia associata alla frattura era cardiovascolare nell’82% dei casi, respiratoria nel 12%, diabetica nel 5% e renale nel 2%.
Un solo paziente ha presentato complicazioni intraoperatorie e 13 pazienti hanno avuto complicazioni postoperatorie. La mortalità postoperatoria è stata del 32%, dovuta in tutti i casi a incidenti cardiovascolari; non è stata dimostrata alcuna relazione con l’eventuale patologia associata alla frattura

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
