Full text linkOvarian tissue cryobanking is considered an available method for preserving female fertility and represents the best option in young pre-pubertal cancer patients. Cryopreservation can be performed on ovarian cortical fragments or on the entire organ. To move forward, the cryopreservation of both avascular ovarian fragments and of whole ovaries must be improved. To this purpose, we performed a detailed comparison between conventional slow freezing and directional freezing on both cortical fragments and whole ovary.
We provide that directional freezing improves the viability of cryopreserved ovarian tissue both in whole ovaries and cortical fragments, but we observed a better preservation of follicles when the samples were frozen as entire organ.
We also developed a perfusion system for ex vivo culture of whole ovary demonstrating that it is possible to maintain alive sheep ovary outside the body for up 4 days. This perfusion culture system could provide a future alternative for women at risk of ovarian involvement due to the threat of reintroducing malignant cells
Crime and criminal policy in Italy : tradition and modernity in a troubled Country
No full textThis paper investigates the development of criminology research in Italy and places it in the context of broader considerations of the country's policies on crime and criminal justice. An overview of Italian research on crime and criminology reveals the versatility of Italian literature and jurisprudence; it also indicates that `new' forms of criminality (such as white-collar crimes, sexual offences and the crimes of immigrants) are being discussed alongside the more traditional topics of murder, crimes against property and organized crime. Furthermore, this survey attempts to clarify why, in Italy, the level of public confidence in the criminal justice system is so low, despite the numerous recent reforms and the official crime rates, according to which Italy is within the European norm for most categories of offences

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
