Genital treatment of penile carcinoma.
No full textSquamous penile carcinoma is an uncommon neoplastic disease with an incidence of
one in 100 000 men per year in Western countries. The role of penile-sparing
treatment represents one of the three main issues in management of squamous
carcinoma of the penis. Most authors consider conservative therapy as an
indicated alternative treatment to partial or total penectomy in small size, low
stage and grade tumours. At present, external or interstitial beam radiotherapy
and lasertherapy represent the best available conservative therapeutic
approaches. Another issue is the role of prophylactic inguinal lymphadenectomy in
patients with negative palpable nodes. An early inguinal lymphadenectomy is
indicated especially in patients with a high occult nodal micrometastases risk
(G3 and pT2-4). The third point of discussion is represented by the use of
chemotherapy in patients with metastatic disease. In this stage of disease,
polychemotherapy with cisplatin, methotrexate and bleomycin seems to be more
effective. The small number of patients investigated and the rapid evolution of
the disease make it extremely difficult to carry out suitable perspective

Territorial government reforms at the time of financial crisis: the dawn of metropolitan cities in Italy
Full text linkOn 1 January 2015 a new institution, the metropolitan city, took its place among the Italian territorial authorities. Despite its incorporation in the Italian
Constitution since 2001, the metropolitan city become a reality only when the national government carried out a process of reform and transformation of Italian territorial government by transforming 10 large cities into metropolitan cities and depriving other intermediate governments (regions and provinces) of their fundamental competences. This article critically reviews the activation of metropolitan cities and the reshuffle of Italian territorial authorities. It stresses the way in which this reform marks the shift towards a new phase of Italian regionalism, which is dominated both by a dynamic of recentralizing intergovernmental relations and by the resulting loss for provincial and regional governments
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
